Detailed Description

Various embodiments of the present application will be described in more detail below with reference to the accompanying drawings. The same reference numbers will be used throughout the drawings to refer to the same or like parts. For clarity, the various features of the drawings are not drawn to scale.

As shown in fig. 1, in a preferred embodiment of the check valve in the present application, the check valve includes a housing 1, a first fluid pipe 5, a first check valve body 31, a second check valve body 32, and a second fluid pipe 2, one ends of the first fluid pipe 5 and the second fluid pipe 2 are inserted into the housing 1, respectively, the first check valve body 31 is disposed in the housing 1 at a position corresponding to a nozzle of the first fluid pipe 5; the second check valve body 32 is disposed at a position corresponding to the orifice of the insertion end of the second fluid pipe 2. Preferably, the first fluid pipe 5 and the second fluid pipe 2 are inserted into the housing 1 from both sides of the partition plate 4, respectively. Because the first fluid pipe 5 and one end of the second fluid pipe 2 are respectively inserted into the housing 1, the fluid flows into the housing 1 from the first fluid pipe 5 and then flows out from the second fluid pipe 2, and the fluid can be silenced in the cavity in the housing 1, so that the one-way valve has the one-way conduction function and the silencing function. In other preferred embodiments, the valve further comprises a plurality of fluid pipes and a plurality of check valve bodies, wherein each fluid pipe is provided with one check valve body at a pipe orifice in the shell 1, or only two fluid pipes are provided with one check valve body at a pipe orifice in the shell 1, but at least one check valve body is provided at a pipe orifice of two fluid pipes in the shell 1, so that, in operation, one part of the check valve bodies is in a normally open state, and the other part of the check valve bodies is used for realizing a one-way conduction function (which will be described in detail later).

In order to further enhance the sound deadening function, a partition plate 4 is provided in the housing 1, and the inner cavity of the housing 1 is partitioned into different chambers by the partition plate 4. The partition board 4 is provided with a through hole 6, and different chambers are communicated through the through hole 6. The first fluid pipe 5 and the second fluid pipe 2 are in different chambers at the mouth of the casing.

The number of the spacers 4 may be one or plural (in the case of having one spacer 4 shown in fig. 1), and when the number of the spacers 4 is plural, the spacers 4 may be disposed parallel to each other or may be disposed non-parallel to each other. Inside the housing 1, a plurality of chambers are formed in such a manner that 1 or more through holes 6 are opened in each partition plate 4, so that adjacent chambers are communicated by the through holes 6, and fluid can be allowed to flow from one chamber to the adjacent other chamber. The more the partition plate 4 is provided, the more remarkable the sound deadening effect.

In a preferred embodiment, the first fluid tube 5 and the second fluid tube 2 are inserted into the housing 1 from two opposite directions, respectively, each tube passing through the last partition 4 in its own direction to the chamber furthest from its insertion point. This avoids having to be in the same chamber as the other tube, and also allows the fluid in the one-way valve to go through a relatively long flow path to eliminate noise as much as possible. In addition, the first fluid pipe 5 and the second fluid pipe 2 are arranged on opposite sides of the shell 1, so that fluid impact force can be balanced, and the service life of the one-way valve can be prolonged.

The first check valve body 31 and the second check valve body 32 have the same structure. The first check valve body 31 includes a first spool 311 and a first spool guide 312; the second check valve body 32 includes a second spool 321 and a second spool guide 322. As shown in fig. 1, the first valve element 311 and the second valve element 321 may be spherical valve elements, conical valve elements, or dome valve elements. Different valve core structures can be adopted according to different working occasions. The first valve core 311 is disposed at a nozzle of the first fluid pipe 5 located in the housing 1, and the first valve core 311 has two positions: a first position to seal off the orifice of the first fluid tube 5 and a second position to open the first fluid tube 5. The first spool guide 312 is used to guide the first spool 311 when the first spool 311 moves, and in a preferred embodiment, one end of the first spool guide 312 is fixed to the inner wall of the housing 1, and the other end is located near the orifice of the first fluid pipe 5 located in the housing 1 or connected to the end of the first fluid pipe 5 located in the housing 1.

The second valve core 321 is disposed at a nozzle of the second fluid pipe 2 located in the housing 1, and the second valve core 321 has two positions: a first position to block the orifice of the second fluid tube 2 and a second position to open the second fluid tube 2. The second spool guide 322 is used to guide the second spool 321 when the second spool 321 moves, and in a preferred embodiment, has one end fixed to the inner wall of the housing 1 and the other end located near the orifice of the second fluid pipe 2 located in the housing 1 or connected to the end of the second fluid pipe 2 located in the housing 1.

The first spool guide 312 and the second spool guide 322 may be frames or perforated tubes so that they can guide the first spool 311 and the second spool 321 without blocking the flow of fluid.

As shown in fig. 1, when no fluid in the first fluid pipe 5 flows in the direction indicated by the arrow in fig. 1, the first valve core 311 is abutted against the pipe orifice of the first fluid pipe 5 under the action of self gravity, and is in the first position of the first valve core 311, so that the flow passage of the fluid is blocked; the second valve core 321 is located at a position far from the orifice of the second fluid pipe 2 under the action of self gravity, and is located at a second position of the second valve core 321. When the flow direction of the fluid in the first fluid pipe 5 is the same as the direction indicated by the arrow in fig. 1, the first valve core 311 moves to the second position against the action of gravity under the pressure of the fluid, and opens the orifice of the first fluid pipe 5, so that the flow path of the fluid is conducted, and a unidirectional conduction function is achieved, and at this time, the second valve core 321 is still in the second position that is opened, and the unidirectional valve in the present application achieves the unidirectional flow function.

In a preferred embodiment, the check valve of the present application is capable of overlapping the original configuration (the configuration shown in fig. 1) after 180 degrees of rotation in the direction shown in fig. 1 (the configuration shown in fig. 2). That is, the first check valve body 31 and the second check valve body 32 are arranged in the housing 1 in a central symmetry manner, and when rotated 180 degrees in the azimuth state shown in fig. 1, the first check valve body 31 and the second check valve body 32 exchange positions, and the structure of the entire check valve is not changed (see fig. 2, the second check valve body 32 is in the open position in fig. 2).

Preferably, the first valve core 311 and the second valve core 321 are configured as a spheroid body comprising a steel inner core and an elastic outer shell, and the valve cores have enough weight, and the outer surfaces have elasticity, so that the pipe orifice to be plugged can be well sealed.

When the check valve is installed in the vertical direction shown in fig. 1, when fluid flows in the direction opposite to the direction shown by the arrow in fig. 1, the first valve core 311 is blocked on the orifice of the first fluid pipe 5 under the action of self gravity and fluid pressure, and the second valve core 321 opens the orifice of the second fluid pipe 2 under the action of self gravity and fluid pressure, so that fluid cannot circulate due to the blocking action of the first valve core 311; when the fluid flows in the direction indicated by the arrow in fig. 1, the fluid pressure in the first fluid pipe 5 is large enough to push the first valve element 311 away to move a certain distance along the first guiding means 312, the fluid enters the chamber located at the upper side in fig. 1, then enters the chamber located at the lower side through the through hole 6 in the partition plate 4, and then the fluid exits the check valve in the present application through the second fluid pipe 2.

When the check valve of the present application is installed in the vertical direction shown in fig. 2 (the installation direction is opposite to that of fig. 1), the first valve element 311 opens the orifice of the first fluid pipe 5 under the action of gravity, and the second valve element 321 seals the orifice of the second fluid pipe 2 under the action of gravity and fluid pressure, so that the fluid cannot circulate due to the sealing action of the second valve element 321; when the fluid flows in the direction indicated by the arrow in fig. 2, the fluid pressure in the second fluid pipe 2 is large enough to push the second valve element 321 away to move a certain distance along the second guiding means 322 (as shown in fig. 2), the fluid enters the chamber located at the upper side in fig. 2, then enters the chamber located at the lower side through the through hole 6 in the partition plate 4, and then the fluid exits the check valve in the present application through the second fluid pipe 2. Therefore, the check valve in the present application has no limitation on the installation direction, and one of the first check valve body 31 and the second check valve body 32 can be in an open state, and the other one can realize a unidirectional conduction function, so that the check valve in the present application can be installed in different directions, and after installation, the unidirectional conduction function of the check valve is not affected, the assembly procedure is simplified, and the installation maintenance cost is reduced.

Fig. 3 shows another embodiment of the check valve in the present application, as shown in fig. 3, a fluid communication pipe 61 is provided on the through hole 6, and the fluid communication pipe 61 communicates chambers on both sides of the partition board 4. The first check valve body 31 and the second check valve body 32 are provided at positions corresponding to both ends of the fluid communication tube 61, respectively. When a plurality of the separators 4 are provided, the fluid communication pipes may be provided in the through holes of the plurality of separators 4, or the fluid communication pipes may be provided in the through holes of only one separator 4. When a plurality of fluid communication tubes are provided, the first check valve body 31 and the second check valve body 32 are provided at positions corresponding to both ends of one of the fluid communication tubes, respectively; when one fluid communication tube is provided, the first check valve body 31 and the second check valve body 32 are provided at positions corresponding to both ends of the fluid communication tube, respectively. Preferably, the plurality of fluid communication tubes and the plurality of check valve bodies are capable of overlapping the original structure after the check valves are rotated 180 degrees in the state shown in fig. 3. This structure can realize the same function.

In the application, since one ends of the first fluid pipe 5 and the second fluid pipe 2 are respectively inserted into the housing 1, fluid can flow into the housing 1 from the first fluid pipe 5 and then flow out from the second fluid pipe 2, and part of noise can be eliminated in the cavity in the housing 1, so that the one-way valve has a silencing function while realizing one-way conduction. Especially after the baffle plate 4 is arranged, the pipe orifices of the first fluid pipe 5 and the second fluid pipe 2 in the shell are positioned in different chambers, so that the flow path of fluid in the one-way valve can be lengthened, and the noise elimination effect is more obvious. In addition, when the check valve is in the working state, one of the first check valve body 31 and the second check valve body 32 is in the open state, and the other one realizes the one-way conduction function, so that the check valve can be installed in different directions, the one-way conduction function of the check valve is not influenced after the installation, the assembly procedure is simplified, and the installation and maintenance cost is reduced.
