Description

Diaphragm type barrier

Technical Field

The invention relates to the technical field of drainage, in particular to a diaphragm type separator.

Background

The pipeline separator is a general name of a device for preventing polluted air and odor from flowing reversely in a drainage pipeline, and adopts various modes such as a deodorization sealing part, a deodorization floor drain, a one-way valve and the like.

The existing pipeline blocking device adopts the principle of a floating ball and a water seal to block. The drain received by the first connecting pipe of the pipeline blocking device flows to the second connecting pipe through the blocking ball moving channel, and the blocking ball moving channel is closed by the water sealing function of the drain stored in the storage space in the blocking device main body and the blocking ball, so that the backflow of polluted air, odor and the like is prevented. Specifically, there is disclosed a drain trap described in chinese patent publication No. CN101155964A, comprising a bottomed cylindrical main body having an internal space communicating with a first connection pipe and a second connection pipe, a lid body, and a partition body dividing the internal space of the main body into a storage space and a discharge space, wherein the partition body is insertable into the internal space, the partition body and a side wall portion of the main body have a sealing portion which receives a pressing force in a vertical direction and which is in close contact with the side wall portion while a force acting on a part of the partition body in the vertical direction is applied to a part of the side wall portion, the partition body is provided with a valve body which floats up to allow a liquid to flow from the storage space to the discharge space when a predetermined amount or more of the liquid is stored in the storage space, and a valve seat which receives and supports the valve body. The drain trap can easily clean the inside of the main body and can precisely seal the storage space and the discharge space which are separated by the partition body. Based on the technical defects in the patent publication of the chinese invention with the publication number "CN 101155964A", the inventor of the present application filed a new application of "a kind of pipeline isolator" in the future to overcome the above-mentioned defects in the prior art and to realize optimization.

However, no matter the scheme described in the chinese patent publication with publication number "CN 101155964A" or the technical scheme applied by the inventor in the past, because the principles are consistent, there is still a systematic defect that is difficult to overcome, and the systematic defect is essentially caused by the floating ball principle, so the above scheme cannot be improved in any way; the method specifically comprises the following steps:

the scheme adopts a floating ball principle, so that control needs to be carried out based on the gravity of a floating ball and the buoyancy of fluid; therefore, the floating ball is limited to move up and down, and the drainage trap can only be transversely arranged but cannot be longitudinally arranged; therefore, the structure is not suitable for blocking a sewer; or at least the above-mentioned structure can be installed only at the lateral pipe position of the sewage, which is very troublesome.

Based on the floating ball principle, the arrangement direction of the drainage trap is limited, and the weight of the floating ball is difficult to grasp. When the floating ball is too heavy, the floating ball is difficult to jack by the buoyancy of the fluid, so that the drainage is not smooth; and when the floater is too light, can't guarantee fine sealed effect between floater and the separation ware main part.

For this reason, it is necessary to make a principle improvement in the above structure of the line block.

The improved principle of the scheme also comes from a Chinese utility model patent document with the publication number of CN210482529U to record a deodorant floor drain made of elastic material, and the deodorant floor drain comprises an integrally formed base and a leakage pipe, the lower end of the leakage pipe forms a V-shaped tangent plane, the V-shaped tangent plane is annularly provided with a protrusion, the leakage pipe is also provided with a valve cover which is integrally formed with the leakage pipe and seals the lower end of the leakage pipe, the inner side of the valve cover is annularly provided with a groove corresponding to the protrusion structure, and the protrusion and the groove are correspondingly provided and seal the V-shaped tangent plane. Compared with the prior art, this utility model a deodorant floor drain of elastic material preparation uses elastic material (silica gel, rubber etc.) preparation simple to operate, integrated into one piece technology, simple structure, and the low price, simple to operate moreover, direct insertion can in the downcomer.

Through analysis, the deodorant floor drain with the results has at least the following two defects:

1, as mentioned above, the odour floor drain is one of the pipe obstructers defined herein. However, through search, the structure is only used in a floor drain at present, but cannot be applied to sewers of kitchen and toilet articles such as counter basins, bathtubs, toilets and the like, and application scenes are few. The main reason is that the deodorization floor drain is not embedded in the pipeline structure as a part of the pipeline, but the structure is simplified.

2, the deodorant floor drain is made of elastic materials (silica gel, rubber and the like), and an iron sheet needs to be inserted into a mold to form an opening between the V-shaped section and the protrusion in the process of forming the product by injection molding of the silica gel and the rubber. However, the opening exists in the forming process, so that the matching of the protrusion and the V-shaped section in the manufactured product is not tight; the effect of preventing air pollution and odor from flowing back is not good.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide a diaphragm type barrier, which prevents the reverse flow of polluted air and odor by means of film type barrier; and the diaphragm type barrier can be arranged in a pipeline structure and used as a part of a pipeline, so that the applicable environment is expanded.

In order to achieve the purpose, the invention adopts the following technical scheme:

the diaphragm type barrier comprises a water inlet pipe, a water outlet pipe and a barrier core body for communicating the water inlet pipe and the water outlet pipe; the method is characterized in that: the barrier device core comprises a core tube, a barrier film and an outer tube, wherein the side wall of the core tube is provided with a U-shaped cut, the edge of the barrier film is connected to the side wall of the U-shaped cut of the core tube, and the outer tube is sleeved on the outer side of the core tube and the barrier film; when the barrier film is impacted by fluid from the inlet direction, the barrier film deforms, and an opening is formed between the bottom of the barrier film and the inner wall of the cut end of the core tube; when the barrier film is in a natural state or is impacted by fluid from the outlet direction, the bottom of the barrier film is attached to the inner wall of the cut end of the core tube to close the opening.

The diaphragm type barrier comprises a water inlet pipe, a water outlet pipe and a barrier core body used for communicating the water inlet pipe and the water outlet pipe. The core body of the barrier device comprises a core body pipe and a barrier film, wherein the barrier film and the core body pipe adopt a film barrier principle, and fluid can pass through only when the barrier film and the core body pipe are impacted by fluid from an inlet direction; and the reverse flow of polluted air and odor is prevented by the blocking function in a natural state or when the fluid impact force from the outlet direction is received.

Further, the diaphragm type separator aims to solve the problem 1 pointed out in the background art, namely, a diaphragm type separator is provided, the diaphragm type separator can be installed in a pipeline structure, specifically, a water inlet pipe is connected to the upstream position of a sewer pipe/air conditioner drain pipe, a water outlet pipe is connected to the downstream position of the sewer pipe/air conditioner drain pipe, and the whole diaphragm type separator is used as a part of a pipeline. Compared with the deodorant floor drain recorded in the Chinese utility model patent with the publication number of CN210482529U, the thin film type blocking anti-odor floor drain expands the applicable environment of the thin film type blocking anti-odor floor drain and is suitable for sewers of kitchen and toilet articles such as counter basins, bathtubs, toilets and the like.

Preferably, the barrier film and the core tube are integrally made of elastic colloid material, and the edge of the barrier film is integrally connected with the side wall of the U-shaped cut of the core tube. In the technical scheme, the blocking rubber sheet and the core body pipe are made of elastic colloid materials integrally, and refer to a deodorant floor drain recorded in a Chinese utility model patent document with the publication number of CN 210482529U; although the problem that the sealing effect of the opening formed by the bottom of the blocking film and the inner wall of the cut end of the core tube is poor exists in the objective integral manufacturing of the elastic colloid material, the requirement of the blocking effect on preventing the polluted air and the odor from flowing back can be met to the greatest extent. And the elastic colloid material is integrally made, so that the structure and the process are simplified, and the cost is reduced. Moreover, the blocking rubber sheet and the core tube are made of elastic colloid materials in an integrated mode, and the blocking rubber sheet and the core tube are elastic in materials and deformation of the blocking rubber sheet and the core tube is correlated with each other, so that a limiting component required to be arranged in the following split arrangement scheme is not needed.

Preferably, the core tube and the blocking film are arranged in a split manner, and the edge of the blocking film and the side wall of the U-shaped cut of the core tube are fixedly connected in a sticking manner or detachably fixed in a clamping manner. In the technical scheme, the core body of the barrier device comprises a core pipe and a barrier film which are arranged in a split mode. The invention aims to solve the problem of the point 2 in the background technology, the core tube and the separation film which are separately arranged are mutually independent in the forming process, and the bonding amount of the separation film and the core tube is redundant through reasonable matching size design; when the bottom of separation film and the incision end inner wall laminating of core body pipe, through the face laminating of longer section, be difficult for producing the clearance to the above-mentioned opening of fine sealed guarantees anti-pollution air and the effect that the foul smell flows against the current.

In the above-mentioned solution, the edge of the barrier film is connected to the side wall of the U-shaped cut of the core tube, and the specific connection manner can be the connection manner of the conventional film, such as adhesion. But relatively speaking, paste to connect fixedly can lead to separation film and core pipe even as an organic whole, install inconvenient and also difficult change under the later stage separation film damage condition, can also can't guarantee in addition that each position of pasting all reaches airtight effect, especially will guarantee not loosen under the fluid erodees the condition yet. In this case, the scheme adopts the following installation mode, specifically, a positioning step surface matched with the U-shaped notch of the core tube is arranged in the tube body of the outer tube; the edge of the blocking rubber sheet is clamped and fixed between the side wall of the U-shaped cut of the core tube and the positioning step surface of the outer tube. In the scheme, the side wall of the U-shaped notch of the core tube and the positioning step surface of the outer tube are adopted to integrally clamp the edge of the barrier film, so that the assembly structure is simplified, and the installation and the replacement are convenient. In addition, the outer pipe is introduced in the scheme, so that the core body of the separator can be arranged in the pipeline to be used as a part of the pipeline, and meanwhile, the outer pipe and the core body pipe are required to be used as a part of the pipeline and are made of hard materials and have certain strength. Therefore, the blocking rubber sheet is pressed and installed on the outer pipe and the core pipe in the scheme, the sealing strength is guaranteed, and looseness caused by fluid impact is avoided.

Preferably, the edge of the barrier film is provided with a flanging, and a flanging groove is formed between the flanging and the barrier film; the side wall of the U-shaped cut of the core tube is embedded in the flanging groove, and the flanging of the blocking film extends to the outer wall of the U-shaped cut. In the technical scheme, the edge of the blocking rubber sheet is provided with a flanging, and the flanging extends to the outer wall of the U-shaped notch. Therefore, the blocking film is connected with the core tube in a wrapping mode, and dislocation is not prone to occurring when the blocking film is pressed on the outer tube and the core tube.

Preferably, a retaining wall is arranged at the notch at the bottom of the flanging groove, and the edge of the end face of the notch end of the core tube is abutted against the retaining wall. In the above solutions, it has been described that the blocking film is press-fitted on the outer tube and the core tube, and the blocking film is first fitted on the side wall of the U-shaped cut of the core tube, and then the core tube and the blocking film thereon are pushed into the outer tube. During the pushing process, the core tube and the outer tube can generate axial displacement; when the blocking film is in contact with the positioning step surface in the outer tube, the blocking film can be subjected to resistance from relative axial movement of the positioning step surface, and if the resistance is not overcome, the blocking film can be axially dislocated relative to the core tube. Therefore, in the scheme, the notch at the bottom of the flanging groove for blocking the film is provided with the blocking wall which is abutted against the edge of the end face of the cut end of the core pipe. Therefore, the resistance of the positioning step surface to the blocking film can be overcome, and the axial dislocation of the blocking film relative to the core tube is avoided. Furthermore, in this case, in combination with the above resistance, the barrier film can be stretched flat in the axial direction, so that the barrier film can be mounted without wrinkles or gaps.

Preferably, a limiting component for limiting the deformation of the barrier film is further arranged inside the tube body of the outer tube.

Preferably, the limiting component is a limiting rib connected to the inner wall of the tube body of the outer tube; the radial height of the limiting ribs is at least not lower than the positioning step surface at the position of the cut end of the core tube, so that the maximum position of the bottom deformation of the blocking film is not higher than the positioning step surface. In the scheme, if the impact force of the fluid from the inlet direction is large, the barrier film cannot recover even under the action of the external force after exceeding a certain deformation amount; the limiting member is required to limit the maximum amount of deformation of the barrier film. Furthermore, the position of the positioning step surface is generally used as the maximum deformation position of the blocking film, so that the radial height of the limiting rib is at least not lower than (generally selected to slightly exceed) the positioning step surface at the position of the cut end of the core tube, and the maximum deformation position of the blocking film does not exceed the positioning step surface, so that the blocking film can be ensured to be successfully reset.

Preferably, the inner wall of the pipe body of the outer pipe is also provided with a pressing edge, and the pressing edge is positioned on the inner wall of the pipe body on the side opposite to the positioning step surface in the radial direction; when the core tube is arranged in the outer tube, the pressing edge acts on the core tube to enable the core tube to generate radial displacement, the side wall of the U-shaped notch of the core tube presses against the positioning step surface of the outer tube, and the edge of the blocking film is clamped; thereby ensuring that the edge of the blocking film is firmly fixed and does not loosen.

Preferably, the water outlet pipe is connected to the outlet end of the outer pipe, and the caliber of the water outlet pipe is matched with the maximum opening caliber formed by the bottom of the blocking film and the inner wall of the cut end of the core pipe. As described above, the barrier film has the maximum deformation position; in this case, the opening formed by the bottom of the barrier film and the inner wall of the slit end of the core tube has the largest caliber. The maximum aperture of the opening limits the flow of the whole blocker, and the flow of the whole blocker cannot be increased even if the aperture of the water outlet pipe is increased. Therefore, only the maximum caliber of the water outlet pipe and the opening needs to be matched, and the matching can be understood as that the caliber of the water outlet pipe is equal to or slightly larger than the maximum caliber of the opening.

Preferably, a mixed flow cavity is arranged in the outer tube between the outlet end of the outer tube and the cut end of the core tube, the maximum opening aperture formed by the bottom of the blocking film and the inner wall of the cut end of the core tube is smaller than the aperture of the mixed flow cavity, and the water outlet tube is communicated with the mixed flow cavity. The above solution has explained that the caliber of the water outlet pipe is equal to or slightly larger than the maximum caliber of the opening, but because the water outlet pipe is a circular pipe, the opening formed by the bottom of the blocking film and the inner wall of the cut end of the core pipe is oval. Even if the flow is almost, due to the difference of the shapes, the direct butt joint of the opening and the water outlet pipe can cause the outlet water at the edge position of the opening to be blocked, so that the outlet water is not smooth and the flow is influenced. In this scheme, with the axial length increase of outer tube, the outer tube inside between outer tube exit end and core tube incision end is equipped with the muddy flow chamber. The water flowing out of the opening firstly passes through the mixed flow cavity and then enters the water outlet pipe; the opening and the water outlet pipe can be integrated through the mixing cavity, and the flow is not influenced.

Preferably, the water inlet pipe is a straight pipe, and the water inlet pipe and the outer pipe are axially arranged in parallel; or the water inlet pipe is a bent pipe, and the axial direction of the inlet end of the water inlet pipe is parallel to the radial direction of the core body pipe facing the U-shaped notch.

In the technical scheme, the diaphragm type barrier has two setting schemes;

the first scheme is that the diaphragm type barrier is longitudinally arranged, the water inlet pipe is a straight pipe at the moment, and the water inlet direction is from top to bottom.

The second solution is that the diaphragm type barrier is arranged transversely. At this moment, the inlet pipe is a bent pipe, and the inlet end of the inlet pipe faces upwards because the barrier is suitable for a sewer and drains water through the gravity of water. In this case, the bottom of the barrier film is required to be located below the opening formed by the inner wall of the slit end of the core tube, and the radial direction of the core tube toward the U-shaped slit is required to be located above the opening.

Example 1:

as shown in fig. 1 to 6, the present embodiment relates to a diaphragm type barrier, which includes a water inlet pipe 1, a water outlet pipe 2, and a barrier core body 3 for communicating the water inlet pipe 1 and the water outlet pipe 2. The barrier device core body 3 comprises a core body tube 31 with a U-shaped cut 311 on the side wall, a barrier film 32 with the edge connected to the side wall of the U-shaped cut 311 of the core body tube 31, and an outer tube 33 sleeved outside the core body tube 31 and the barrier film 32. When the barrier film 32 is subjected to a fluid impact force from the inlet direction, the barrier film 32 deforms and an opening 34 is formed between the bottom of the barrier film 32 and the inner wall of the slit end of the core tube 31. When the barrier film 32 is in a natural state or is subjected to a fluid impact force from the outlet direction, the bottom of the barrier film 32 fits against the inner wall of the cut end of the core tube 31 to close the opening 34. This technical scheme relates to a diaphragm formula separation ware, this diaphragm formula separation ware, including inlet tube 1, outlet pipe 2 to and be used for the intercommunication the separation ware core 3 of inlet tube 1 and outlet pipe 2. The baffle core 3 comprises a core tube 31 and a baffle film 32, wherein the baffle film 32 and the core tube 31 adopt a film type baffle principle, and the fluid can only pass through when the fluid impact force from the inlet direction is received. And the reverse flow of polluted air and odor is prevented by the blocking function in a natural state or when the fluid impact force from the outlet direction is received.

In a further preferred scheme, the water outlet pipe 2 is connected to the outlet end of the outer pipe 33, and the caliber of the water outlet pipe 2 is matched with the caliber of the maximum opening 34 formed by the bottom of the barrier film 32 and the inner wall of the cut end of the core pipe 31. As described above, the barrier film 32 has the maximum deformation position. In this case, the opening 34 formed by the bottom of the barrier film 32 and the slit end inner wall of the core tube 31 has the largest diameter. The maximum diameter of the opening 34 limits the flow rate of the entire baffle, and even if the diameter of the outlet pipe 2 is increased, the flow rate of the entire baffle cannot be increased. Therefore, only the maximum caliber of the outlet pipe 2 and the opening 34 needs to be adapted, and the adaptation here can be understood as that the caliber of the outlet pipe 2 is equal to or slightly larger than the maximum caliber of the opening 34. In addition, a mixed flow cavity 35 is arranged in the outer tube 33 between the outlet end of the outer tube 33 and the cut end of the core tube 31, the caliber of a maximum opening 34 formed by the bottom of the barrier film 32 and the inner wall of the cut end of the core tube 31 is smaller than that of the mixed flow cavity 35, and the water outlet tube 2 is communicated with the mixed flow cavity 35. The above solution has explained that the caliber of the water outlet pipe 2 is equal to or slightly larger than the maximum caliber of the opening 34, but because the water outlet pipe 2 is a circular pipe, the opening 34 formed by the bottom of the barrier film 32 and the inner wall of the cut end of the core pipe 31 is oval. Even if the flow rate is almost the same, due to the difference in shape, the direct butt joint of the opening 34 and the water outlet pipe 2 can cause the outlet water at the edge position of the opening 34 to be blocked, so that the outlet water is not smooth, and the flow rate is affected. In this embodiment, the axial length of the outer tube 33 is increased, and a mixing chamber 35 is provided inside the outer tube 33 between the outlet end of the outer tube 33 and the cut end of the core tube 31. The water flowing out of the opening 34 firstly passes through the mixing cavity 35 and then enters the water outlet pipe 2. The above-mentioned opening 34 and the outlet pipe 2 can be integrated by the mixing chamber 35 without affecting the flow.

Based on the technical scheme, the diaphragm type barrier has two setting schemes.

The first scheme is that as shown in fig. 6, the diaphragm type barrier is longitudinally arranged, at the moment, the water inlet pipe 1 is a straight pipe, the water inlet direction is from top to bottom, and the water inlet pipe 1 and the outer pipe 33 are axially arranged in parallel.

A second alternative is that the membrane barrier is laterally disposed as shown in figures 3 or 4 or 5. At this time, the inlet pipe 1 is a bent pipe, and the inlet end of the inlet pipe 1 faces upward because the barrier is suitable for a sewer and drains water by the gravity of water. In this embodiment, the bottom of the barrier film 32 is required to be located below the opening 34 formed by the inner wall of the slit end of the core tube 31, and the radial direction of the core tube 31 toward the U-shaped slit 311 is required to be located above; the inlet end axial direction of the inlet tube 1 is parallel to the radial direction of the core tube 31 towards the U-shaped cutout 311.

As shown in the figure, the inlet tube 1 is connected on the outer tube 33, specifically, the inlet tube 1 is provided with the threaded seat 11, the water inlet end cover of the outer tube 33 is arranged inside the threaded seat 11, and is connected on the threaded seat 11 through the threaded sleeve 4, so that the outer tube 33 and the threaded seat 11 are pressed and fixed, and the connection of the inlet tube 1 and the outer tube 33 is realized. In the second embodiment, because the inlet end of the water inlet pipe 1 needs to be oriented, the guide grooves 12 and the guide ribs 13 need to be respectively arranged on the inner wall of the threaded seat 11 and the outer wall of the outer pipe 33, so as to ensure the accuracy of the installation orientation of the water inlet pipe 1.

The embodiment provides a diaphragm type separator, and the diaphragm type separator can be installed in a pipeline structure, specifically, an upstream position of a water inlet pipe 1 connected to a sewer pipe/air conditioner drain pipe, a downstream position of a water outlet pipe 2 connected to the sewer pipe/air conditioner drain pipe, and the whole diaphragm type separator is used as a part of a pipeline. Compared with the deodorant floor drain recorded in the Chinese utility model patent with the publication number of CN210482529U, the thin film type blocking anti-odor floor drain expands the applicable environment of the thin film type blocking anti-odor floor drain and is suitable for sewers of kitchen and toilet articles such as counter basins, bathtubs, toilets and the like. In addition, this solution has an advantage over the drainage trap using the floating ball principle described in the chinese patent publication No. CN101155964A in that it can use the horizontally disposed or vertically disposed solution as shown in fig. 3 to 6, whereas the drainage trap using the floating ball principle can use only the horizontally disposed solution. And the most important is that when the drainage trap based on the floating ball principle drains water, the drainage is performed in a mode that liquid floats upwards and overflows, the water flow speed is relatively slow, and magazines and sediments in the pipeline cannot be washed away. The blocking film in the scheme has certain elastic support, so that water in the tube can be accumulated under the elasticity of the blocking film to obtain certain potential energy; when the opening can not be opened by the elasticity of the blocking film, more water is accumulated to form larger impact force, so that the diaphragm type blocking device and the pipeline at the downstream of the diaphragm type blocking device can be flushed, and the aim of cleaning is fulfilled.

The present embodiment is characterized in that the barrier film 32 and the core tube 31 are integrally made of elastic gel material, and the edge of the barrier film 32 is integrally connected with the side wall of the U-shaped notch 311 of the core tube 31. In the technical scheme, the separation film 32 and the core body pipe 31 are made of elastic colloid materials integrally, and refer to the deodorant floor drain recorded in the Chinese utility model patent document with the publication number of CN 210482529U. Although the problem that the sealing effect of the opening 34 formed by the bottom of the barrier film 32 and the inner wall of the cut end of the core tube 31 is not good exists in the objective integral manufacturing of the elastic colloid material, the requirement of the barrier function for preventing the polluted air and the odor from flowing backwards can be met to a great extent. And the elastic colloid material is integrally made, so that the structure and the process are simplified, and the cost is reduced. In addition, it should be noted that the barrier film 32 and the core tube 31 are made of elastic colloid material, and both have material elasticity, and the deformation of the two is correlated with each other, so that a limit component required to be arranged in the split arrangement scheme in embodiment 2 is not required.

Example 2:

as shown in fig. 1 to 12, the present embodiment also relates to a diaphragm type barrier, which has the same principle as the technical solution described in embodiment 1, and each barrier includes a water inlet pipe 1, a water outlet pipe 2, and a barrier core body 3 for communicating the water inlet pipe 1 and the water outlet pipe 2; the barrier core body 3 also comprises a core body tube 31 with a U-shaped notch 311 on the side wall, a barrier film 32 with the edge connected to the side wall of the U-shaped notch 311 of the core body tube 31, and an outer tube 33 sleeved outside the core body tube 31 and the barrier film 32. In addition, the water inlet pipe 1, the water outlet pipe 2 and the mixed flow cavity 35 in the outer pipe 33 are all consistent; reference is made to example 1 without being repeated here.

This example differs from example 1 in that: the core tube 31 and the blocking film 32 are arranged separately, and the edge of the blocking film 32 is fixedly connected with the side wall of the U-shaped notch 311 of the core tube 31 in a sticking manner or detachably fixed in a clamping manner. In this technical solution, the barrier core body 3 includes a core tube 31 and a barrier film 32 which are separately arranged. This embodiment aims at solving the 2 nd problem of pointing out among the above-mentioned background art, and the core pipe 31 and the separation film 32 that the components of a whole that can function independently set up are independent each other in the forming process, through reasonable cooperation size design, can make separation film 32 and core pipe 31 laminating volume redundant. When the bottom of the barrier film 32 is attached to the inner wall of the cut end of the core tube 31, a gap is not easily generated by the attachment of a long section of surface, so that the opening 34 is well sealed, and the effect of anti-pollution air and odor backflow is ensured.

In the above-mentioned solution, the edge of the barrier film 32 is connected to the side wall of the U-shaped notch 311 of the core tube 31, and the specific connection method can be a conventional film connection method, such as gluing. But relatively speaking, paste to connect fixedly can lead to separation film 32 and core pipe 31 to be even as an organic whole, and the installation is inconvenient and also difficult the change under the later stage separation film 32 damaged condition, also can't guarantee in addition that each position of pasting all reaches airtight effect, especially will guarantee not loosen under the fluid erodees the condition. In this case, the present embodiment adopts the following installation manner, specifically, a positioning step surface 331 adapted to the U-shaped notch 311 of the core tube 31 is provided inside the tube body of the outer tube 33. The edge of the barrier film 32 is clamped and fixed between the side wall of the U-shaped notch 311 of the core tube 31 and the positioning step surface 331 of the outer tube 33. In the scheme, the side wall of the U-shaped notch 311 of the core tube 31 and the positioning step surface 331 of the outer tube 33 are adopted to integrally clamp the edge of the barrier film 32, so that the assembly structure is simplified, and the installation and the replacement are convenient. In addition, the outer pipe 33 is introduced in the scheme, so that the core body 3 of the barrier device can be arranged in the pipeline as a part of the pipeline, and meanwhile, the outer pipe 33 and the core body pipe 31 are required to be used as a part of the pipeline, so that the core body pipe is made of hard materials and has certain strength. Therefore, the outer tube 33 and the core tube 31 press-fit the barrier film 32 in the scheme, so that the sealing strength is ensured, and the looseness caused by fluid impact is avoided.

On the basis of the technical scheme, the edge of the barrier film 32 is provided with a flange 321, and a flange groove 322 is formed between the flange 321 and the barrier film 32. The side wall of the U-shaped cut 311 of the core tube 31 is embedded in the flanging groove 322, and the flanging 321 of the blocking film 32 extends to the outer wall of the U-shaped cut 311. In the technical scheme, the edge of the barrier film 32 is provided with a flange 321, and the flange 321 extends to the outer wall of the U-shaped notch 311. Therefore, the barrier film 32 and the core tube 31 are connected in a wrapping manner, and the outer tube 33 and the core tube 31 are not easy to generate dislocation when the barrier film 32 is pressed and installed. A blocking wall 323 is arranged at the notch at the bottom of the flanging groove 322, and the edge of the end face of the notch end of the core body pipe 31 is abutted against the blocking wall 323. In the above-mentioned solution, it has been described that the outer tube 33 and the core tube 31 are used to press-fit the barrier film 32, and the barrier film 32 is first mounted on the side wall of the U-shaped notch 311 of the core tube 31, and then the core tube 31 and the barrier film 32 thereon are pushed into the outer tube 33. During this pushing, the core tube 31 and the outer tube 33 are displaced in the axial direction. When the barrier film 32 comes into contact with the positioning step surface 331 in the outer tube 33, the resistance from the relative axial movement of the positioning step surface 331 is received, which may cause the barrier film 32 to be axially misaligned with respect to the core tube 31. In the above-described aspect, therefore, the notch at the bottom of the turned-over groove 322 of the barrier film 32 is provided with a blocking wall 323, and the blocking wall 323 abuts against the edge of the notched end face of the core tube 31. Therefore, the resistance of the positioning step surface 331 to the barrier film 32 can be overcome, and the axial dislocation of the barrier film 32 relative to the core tube 31 is avoided. Further, this arrangement, in combination with the resistance, also allows the barrier film 32 to stretch flat in the axial direction, so that the barrier film 32 is mounted without wrinkles and gaps. It should be noted that, because the core tube 31, the baffle film 32, and the outer tube 33 are required to be mounted, the core tube 31 is required to be pushed into the outer tube 33 at a specific angle, and the guide grooves 12 and the guide ribs 13 are provided on the outer wall of the core tube 31 and the inner wall of the outer tube 33, respectively. Meanwhile, in order to take out the core tube, a handle 312 is arranged on the inner wall of the core tube.

In addition, a limiting component for limiting the deformation of the barrier film 32 is further arranged inside the tube body of the outer tube 33. The stopper may be a curved surface formed by the inner wall of the outer tube 33 and completely overlapped with the positioning step surface 331, or may be a stopper rib 332 attached to the inner wall of the outer tube 33 as shown in the figure. The radial height of the limiting rib 332 is at least not lower than the positioning step surface 331 at the position of the cut end of the core tube 31, so that the maximum deformation position of the bottom of the barrier film 32 is not higher than the positioning step surface 331. In the above-described embodiment, if the barrier film 32 is deformed more than a certain amount due to a large fluid impact force from the inlet direction, the barrier film 32 cannot be restored even when the external force is removed. The positioning of the stop member is required to limit the maximum amount of deformation of the barrier film 32. Further, the position of the positioning step surface 331 is generally used as the maximum deformation position of the barrier film 32, so the radial height of the limiting rib 332 is not lower than (generally selected to slightly exceed) the positioning step surface 331 at least at the position of the cut end of the core tube 31, and thus the maximum deformation position of the barrier film 32 does not exceed the positioning step surface 331, and the barrier film 32 can be ensured to be successfully reset.

In addition, a pressing rib 333 is further provided on the inner wall of the outer tube 33, and the pressing rib 333 is located on the inner wall of the tube on the side opposite to the positioning step surface 331 in the radial direction. When the core tube 31 is fitted into the outer tube 33, the pressing rib 333 acts on the core tube 31 to displace it radially, and the side wall of the U-shaped slit 311 of the core tube 31 presses against the positioning step surface 331 of the outer tube 33 and clamps the edge of the barrier film 32. Thereby ensuring that the edges of the barrier film 32 are securely held against loosening.
