In the following, a water treatment facility with a shut-off mechanism provided by the present application will be described in detail.
Example one
Referring to fig. 1-13, a water treatment facility with a shut-off mechanism according to an embodiment of the present application includes a facility body 2 and at least one flexible shut-off mechanism 1.
Wherein the installation body 2 is provided with a water inlet pipe 21 and at least one water outlet pipe 22. It is understood that the number of the flexible cut-off mechanism 1 in the embodiment of the present application may be 1 or more, and the number of the water outlet pipe 22 in the installation body 2 may also be 1 or more.
For example:
as an implementation manner of the embodiment of the present application, please refer to fig. 9-10, the number of the flexible intercepting mechanism 1 is one, the number of the water outlet pipe 22 is one, at this time, the water outlet pipe 22 is connected to the natural water body through a downstream pipeline, and the flexible intercepting mechanism 1 is fixed at a pipe orifice portion of the water outlet pipe 22 to intercept or release the water entering the water outlet pipe 22.
As another implementation manner of the embodiment of the present application, please refer to fig. 11-12, where the number of the flexible intercepting mechanism 1 is one, and the number of the water outlet pipes 22 is two, in this case, one of the water outlet pipes 22 may be connected to a natural water body through a downstream pipeline, the other water outlet pipe 22 may be connected to a sewage treatment plant or a sewage storage tank through a downstream pipeline, and the flexible intercepting mechanism 1 is fixed at a pipe orifice portion of any one of the water outlet pipes 22 to intercept or release water entering the water outlet pipe 22.
As another implementation manner of the embodiment of the present application, please refer to fig. 13, the number of the flexible intercepting mechanisms 1 may be two, the number of the water outlet pipes 22 is two, at this time, one of the water outlet pipes 22 may be connected to a natural water body through a downstream pipeline, the other water outlet pipe 22 may be connected to a sewage treatment plant or a sewage storage tank through a downstream pipeline, and each flexible intercepting mechanism 1 is fixed at a pipe orifice portion of the corresponding one of the water outlet pipes 22.
Of course, it will be understood by those skilled in the art that the above matching numbers for the flexible shut-off mechanism 1 and the outlet pipe 22 are merely three examples, and are not limiting. In other words, the present invention is applicable to a plurality of (greater than or equal to 1) water outlet pipes 22 provided in the facility body 2, and to a plurality of (greater than or equal to 1) embodiments of the flexible cut-off mechanism 1.
As an embodiment of the flexible cut-off mechanism 1, please refer to fig. 1 to 4, which may include: a flexible sleeve 12 and a valve body 15. Wherein the flexible sleeve 12 has a chamber 11 which can be filled with a filling material; the valve body 15 has a flow passage 151 for externally connecting a pipe (such as a pipe inlet or a pipe outlet of a flow distribution well), and a slide groove 152 for allowing the flexible sleeve 12 to slide up and down in the valve body 15; the flexible sleeve 12 is disposed within the chute 152 and sealingly connected to the valve body 15. The slide groove 152 communicates with the flow passage 151.
In the embodiment of the flexible shut-off mechanism 1, the flow channel 151 can be understood as a channel for water or other flowing liquid to flow through after communicating with the pipe inlet or the pipe outlet of the diversion well, and the flexible sleeve 12 can be a flexible air bag with contraction and expansion functions, and the expansion of the air bag can be realized by filling the chamber 11 inside the flexible sleeve 12 with filler, or the contraction of the air bag can be realized by discharging the filler from the chamber 11 inside the flexible sleeve 12. Meanwhile, the flexible sleeve 12 during expansion or contraction can slide up and down in the sliding groove 152 shown in fig. 1, that is, when the flexible sleeve 12 is expanded, the flexible sleeve slides down from the sliding groove 152 to the flow channel 151 and fits with the bottom of the flow channel 151, and then the flow is stopped; the flexible sleeve 12 slides upwards from the flow channel 151 to the sliding groove 152 when being contracted, and when the flexible sleeve 12 slides upwards to be separated from the bottom of the flow channel 151, the gradual conduction of the flow channel 151 is realized; those skilled in the art will appreciate that such a structure is designed such that the flexible sleeve 12 does not need to be sleeved outside the steel housing as in the prior art, and the flexible sleeve 12 does not need to envelop the whole steel housing, but only the flexible sleeve 12 needs to slide in the sliding groove 152 of the valve body 15 by expansion or contraction, so that the fitting area between the flexible sleeve 12 and the flow passage 151 is greatly reduced, and since the moving area of the expansion or contraction of the flexible sleeve 12 is longitudinally moved relative to the flow passage 151 and does not occupy a transverse space, the flexible sleeve 12 does not need to be transversely installed in the well when being applied to a shunt well, and the flexible sleeve has the characteristic of occupying a very small space.
In addition, in the process of realizing interception, as the flexible sleeve 12 slides downwards to the flow channel 151 through the sliding groove 152 and is attached to the bottom of the flow channel 151 when expanding, the contact sealing between the flexible sleeve 12 and the bottom of the flow channel 151 is surface contact, compared with the point contact in the prior art, the flexible sleeve 12 can achieve a better sealing effect, namely, a better interception effect is achieved, and in order to keep good sealing of the flexible sleeve 12 in the expansion process, the flexible sleeve 12 can be expanded in the expansion state permanently, and the flexible sleeve 12 arranged in the sliding groove 152 is in sealing connection with the valve body 15 in the embodiment.
For the flexible sleeve 12, the flexible sleeve 12 may be a balloon with flexible contraction or expansion function, the inside of the balloon is hollow to form a chamber 11, and of course, the flexible sleeve 12 is further optimized as the balloon; the flexible sleeve 12 may also have an open port 121 and a chamber 11 extending inwardly from the open port 121 to form a sealed structure, the open port 121 being adapted to fit into the slot of the sliding chute 152 and being sealingly connected to the slot of the sliding chute 152 through the open port 121. In particular, the open port 121 of the flexible sleeve 12 can be understood as an inlet for filling the chamber 11 with the filler, which enters the chamber 11 of the closed structure through the open port 121 and forms an expansion inside the chamber, and when the filler needs to be discharged, it is also discharged from the open port 121. It will be appreciated by those skilled in the art that the open port 121 is adapted to, i.e., sized and shaped to correspond to, the slot of the chute 152 such that the open port 121 sealingly engages the slot of the chute 152.
It should be noted that, in the embodiment of the present application, the flexible sleeve 12 is adapted to the shape of the sliding groove 152 and is attached to the inner side wall of the sliding groove 152, the inner side wall of the sliding groove 152 is inclined inward in the direction from one end of the slot to the other end of the sliding groove 152, that is, inclined inward in the vertical direction, and the port diameter of the slot is greater than the port diameter of the other end, it can be understood that the flexible sleeve 12 is the flexible sleeve 12 in the prefabricated shape, the prefabricated shape is adapted to the shape of the sliding groove 152, and the interface of the sliding groove 152 has a certain taper by the inner side wall of the sliding groove 152 being inclined inward in the direction from one end of the slot to the other end of the sliding groove 152, so that the flexible sleeve 12 in the prefabricated shape can be rapidly expanded to the bottom of the flow passage and attached to the bottom of the flow passage during the process of filling the filler, thereby improving the efficiency.
Further, in an embodiment of the flexible shut-off mechanism 1, the flexible shut-off mechanism 1 further includes: a gland 13, the gland 13 being fixed to the slot to seal the open port 121 and the slot; the cover 13 is formed with a through hole 131, and the chamber 11 can be filled or discharged with the filler through the through hole 131. In order to achieve a better sealing effect between the open port 121 and the sliding groove 152, the notch is bent outward in a direction perpendicular to the sliding direction of the flexible sleeve 12, so that two opposite side boundaries of the notch are L-shaped, and the open port 121 of the flexible sleeve 12 fits the bent portion of the notch and extends outward, so that the pressing cover 13 fits the open port 121 extending outward and is bolted (e.g., screwed, bolted, etc.) with the bent portion of the sliding groove 152. This achieves that the open port 121 of the flexible sleeve 12 is completely sealed from the slot by the gland 13 when the slot of the chute 152 is in position. Meanwhile, a reinforcing rib plate 153 is further provided at the bent portion in order to reinforce fastening.
Of course, the notch can also be provided with a flange; the open port 121 is provided with a flange connecting part matched with the flange plate; the gland 13 is attached to the flange connecting part and connected with a flange plate flange, and a reinforcing rib plate 153 is arranged between the flange plate and the notch.
Those skilled in the art can understand that, for the sealing connection between the notch of the chute and the flexible sleeve, the connection may be a bolt connection of the L-shaped bending structure or a flange connection of the flange structure, and the embodiment of the present invention is not limited thereto, and any connection method that can achieve relative sealing between the notch of the chute and the flexible sleeve is suitable for the present invention.
Among them, regarding the distribution manner of the flow passage 151 and the slide groove 152, the flow passage 151 is distributed laterally in the valve body 15, and the slide groove 152 is distributed longitudinally in the valve body 15, that is, the flow passage 151 and the slide groove 152 are perpendicular to each other, and also in order to enhance the fastening, a reinforcing rib plate 153 is provided at a perpendicular intersection portion of the flow passage 151 and the slide groove 152. Of course, it will be understood by those skilled in the art that the vertical distribution of the through-flow channel 151 and the chute 152 relative to each other is not absolute, and in alternative embodiments, when there is a deviation in the vertical direction of the chute 152 relative to the through-flow channel 151, or a distribution that is directly inclined, it is possible to achieve a minimum space occupation without installing it entirely transversely in the well when it is used in a flow splitting well, since its movement zone, which also corresponds to the expansion or contraction of the flexible sheath 12, is moved longitudinally or close to longitudinally relative to the through-flow channel 151, and does not occupy transverse space. Therefore, the distribution of the positions of the flow channels 151 and the chutes 152 is applicable to the embodiments of the present invention and is within the scope of the present invention.
As another embodiment of the flexible cut-off mechanism 1, please refer to fig. 5 to 8, which may include: a flexible sleeve 12, a shutter 14 and a valve body 15. Wherein the flexible sleeve 12 has a chamber 11 which can be filled with a filling material; the valve body 15 has a flow passage 151 for externally connecting a pipe (such as a pipe inlet or a pipe outlet of a flow distribution well), and a slide groove 152 for allowing the flexible sleeve 12 to slide up and down in the valve body 15; the shutter 14 and the flexible sleeve 12 are both disposed within the chute 152; the flashboard 14 is fixedly connected with the flexible sleeve 12, and the flexible sleeve 12 is hermetically connected with the valve body 15; the slide groove 152 communicates with the flow passage 151.
Further, in order to facilitate quick installation between the circulation channel 151 and the pipeline, in the embodiment of the present application, two ports for externally connecting the pipeline are correspondingly disposed at two ends of the circulation channel 151, and the two ports extend outwards in a circulation direction (i.e., a transverse direction shown in the drawing) of the circulation channel 151 and are correspondingly distributed at two sides of the sliding groove 152. Therefore, the two corresponding interfaces can be connected with an external pipeline through bolts or directly and correspondingly inserted into the external pipeline to be clamped with the external pipeline.
Similarly, the flow channel 151 can be understood as a channel for flowing water or other fluid after communicating with a pipe inlet or a pipe outlet of a diversion well, and the flexible sleeve 12 can be a flexible air bag with contraction and expansion functions, and the expansion of the air bag can be realized by filling the chamber 11 inside the flexible sleeve 12 with filler or the contraction of the air bag can be realized by discharging the filler from the chamber 11 inside the flexible sleeve 12. Meanwhile, the flexible sleeve 12 during expansion or contraction can slide up and down in the chute 152 as shown in fig. 1, and since the shutter plate 14 is fixedly connected with the flexible sleeve 12, that is, the flexible sleeve 12 drives the shutter plate 14 to slide down from the chute 152 to the flow channel 151 during expansion, and when the shutter plate 14 is attached to the bottom of the flow channel 151, the flow is stopped; the flexible sleeve 12 drives the shutter plate 14 to slide upwards from the flow channel 151 to the chute 152 when being contracted, and realizes gradual conduction of the flow channel 151 when the shutter plate 14 slides upwards to be separated from the bottom of the flow channel 151; those skilled in the art will appreciate that such a structure is designed such that the flexible sleeve 12 does not need to be sleeved outside the steel housing as in the prior art, and the flexible sleeve 12 does not need to envelop the whole steel housing, but only the flexible sleeve 12 needs to slide in the sliding groove 152 of the valve body 15 by expansion or contraction, so that the fitting area between the flexible sleeve 12 and the flow passage 151 is greatly reduced, and since the moving area of the expansion or contraction of the flexible sleeve 12 is longitudinally moved relative to the flow passage 151 and does not occupy a transverse space, the flexible sleeve 12 does not need to be transversely installed in the well when being applied to a shunt well, and the flexible sleeve has the characteristic of occupying a very small space.
In addition, in the process of realizing closure, because the flexible sleeve 12 drives the gate plate 14 to slide downwards to the circulation channel 151 from the sliding groove 152 and to be attached to the bottom of the circulation channel 151 when expanding, the contact sealing between the gate plate 14 and the bottom of the circulation channel 151 is surface contact, which can achieve better sealing effect compared with the point contact in the prior art, that is, achieve better closure effect, and in order to keep good sealing of the flexible sleeve 12 in the expansion process, the flexible sleeve 12 arranged in the sliding groove 152 can be expanded durably in the expansion state, and in the embodiment, the flexible sleeve 12 is connected with the valve body 15 in a sealing manner.
Similarly, the flexible sleeve 12 has an open port 121, and a chamber 11 of a closed structure is formed by extending the open port 121 inwards, and the open port 121 is matched with the slot of the sliding chute 152 and is connected with the slot of the sliding chute 152 in a sealing way through the open port 121. And the top of the shutter 14 is fixed to the other end of the flexible sleeve 12 opposite the open port 121. In particular, the open port 121 of the flexible sleeve 12 can be understood as an inlet for filling the chamber 11 with the filler, which enters the chamber 11 of the closed structure through the open port 121 and forms an expansion inside the chamber, and when the filler needs to be discharged, it is also discharged from the open port 121. It will be appreciated by those skilled in the art that the open port 121 is adapted to, i.e., sized and shaped to correspond to, the slot of the chute 152 such that the open port 121 sealingly engages the slot of the chute 152.
Further, in an embodiment of the flexible shut-off mechanism, it further comprises: a gland 13, the gland 13 being fixed to the slot to seal the open port 121 and the slot; the cover 13 is formed with a through hole 131, and the chamber 11 can be filled or discharged with the filler through the through hole 131. In order to achieve a better sealing effect between the open port 121 and the sliding groove 152, the notch is bent outward in a direction perpendicular to the sliding direction of the flexible sleeve 12, so that two opposite side boundaries of the notch are L-shaped, and the open port 121 of the flexible sleeve 12 fits the bent portion of the notch and extends outward, so that the pressing cover 13 fits the open port 121 extending outward and is bolted (e.g., screwed, bolted, etc.) with the bent portion of the sliding groove 152. This achieves that the open port 121 of the flexible sleeve 12 is completely sealed from the slot by the gland 13 when the slot of the chute 152 is in position. Meanwhile, a reinforcing rib plate 153 is further provided at the bent portion in order to reinforce fastening.
In this embodiment of the flexible shut-off mechanism, the flow passage 151 is distributed laterally in the valve body 15, the slide groove 152 is distributed longitudinally in the valve body 15, that is, the flow passage 151 and the slide groove 152 are perpendicular to each other, and also in order to enhance the fastening, a reinforcing rib plate 153 is provided at a perpendicular intersection of the flow passage 151 and the slide groove 152. Of course, it will be understood by those skilled in the art that the vertical distribution of the through-flow channel 151 and the chute 152 relative to each other is not absolute, and in alternative embodiments, when there is a deviation in the vertical direction of the chute 152 relative to the through-flow channel 151, or a distribution that is directly inclined, it is possible to achieve a minimum space occupation without installing it entirely transversely in the well when it is used in a flow splitting well, since its movement zone, which also corresponds to the expansion or contraction of the flexible sheath 12, is moved longitudinally or close to longitudinally relative to the through-flow channel 151, and does not occupy transverse space. Therefore, the distribution of the positions of the flow channels 151 and the chutes 152 is applicable to the embodiments of the present invention and is within the scope of the present invention.
Further, in the embodiment of the flexible shutoff mechanism 1, in order to enable the flexible sleeve 12 to better carry the shutter 14 to move during the expansion or contraction process, the flexible shutoff mechanism further includes a pressure plate 16, and the pressure plate 16 is fixed in the chamber 11 and located at the bottom of the chamber 11 to fit the top of the shutter 14 and is fixedly connected with the top of the shutter 14, such as bolted connection or screwed connection.
As an operation state of the embodiment of the present application, referring to fig. 3-4 or 7-8, when the chamber 11 is filled with the filler, the flexible sleeve 12 starts to expand until the bottom of the flexible sleeve 12 abuts against the bottom of the flow channel 151 and seamlessly engages with the bottom of the flow channel 151, thereby achieving the shut-off of the flow channel 151.
As a further operating condition of the embodiment of the present application, with reference to fig. 1-2 or 5-6, when the chamber 11 is emptied of the filling material, the flexible sleeve 12 starts to contract until the bottom of the flexible sleeve 12 is located at the top portion of the through-flow channel 151, thereby achieving complete communication of the through-flow channel 151.
That is, in the embodiment of the present application, the expansion of the airbag is achieved by filling the chamber 11 inside the flexible sheath 12 with the filler, or the contraction of the airbag is achieved by discharging the filler from the chamber 11 inside the flexible sheath 12. Meanwhile, the flexible sleeve 12 during the expansion or contraction process can slide up and down in the sliding groove 152, that is, the flexible sleeve 12 slides down to the circulation channel 151 from the sliding groove 152 during the expansion, or drives the gate plate 14 to slide down to the circulation channel 151 from the sliding groove 152 and to be attached to the bottom of the circulation channel 151, so that the closure is realized; when the flexible sleeve 12 is contracted, the flexible sleeve slides upwards from the flow channel 151 to the sliding groove 152, and when the flexible sleeve 12 slides upwards to be separated from the bottom of the flow channel 151, or drives the flashboard 14 to slide upwards to be separated from the bottom of the flow channel 151, the gradual conduction of the flow channel 151 is realized; the structure design enables the flexible sleeve not to be sleeved outside the steel outer cover as in the prior art, and the flexible sleeve is not required to envelop the whole steel outer cover, but only needs to be expanded or contracted to slide in the chute of the valve body, so that the joint area of the flexible sleeve and the circulation channel is greatly reduced, when the flexible sleeve is installed in a water treatment facility such as a diversion well, the flexible sleeve only needs to be connected with any pipe orifice (a water inlet pipe or a water outlet pipe), and the whole flexible sleeve does not need to be transversely installed in the well, so that the occupied space is extremely small.
In addition, in the embodiment of the present application, as shown in fig. 10 or 12, the flexible shut-off mechanism 1 may be fixed to the nozzle portion of the water outlet pipe 22 by flange-mounting the valve body 15. Or as shown in fig. 9 or 11, the flexible cut-off mechanism 1 may be fixed at the pipe orifice of the water outlet pipe 22 by the valve body 15 in a wall-attachment mounting manner, and for a flange-type or wall-attachment specific mounting manner, an installation manner in the prior art may be adopted, which is not described in detail in this embodiment.
Finally, it is necessary to supplement that the filling material in the embodiment of the present application may be a gas (such as air, nitrogen, inert gas, etc.) or a liquid (such as hydraulic oil, water), etc. Preferably, the filling material is selected from gases, which can be rapidly filled or discharged, so that the flexible sleeve 12 can be rapidly expanded or contracted, and then the technical effect of rapid closure or passing can be achieved.
Example two
Corresponding to the first embodiment of the present application, a second embodiment of the present application provides a drainage system, which includes the water treatment facility provided in the first embodiment of the present application, and it is understood that the drainage system may be any drainage system in a pipe network system, and when the drainage system includes the water treatment facility provided in the first embodiment of the present application, and when the diversion well, the intercepting well, the installation well, the storage tank, or other tank structures need to be intercepted, a flexible intercepting mechanism in the water treatment facility may be used to intercept, so as to replace a pipe-shaped rubber sleeve used in the prior art, a sealed chamber is formed between the rubber sleeve and the steel housing, when the chamber is inflated, the rubber sleeve is deformed to form 3 points or 4 points and is closed, and when the chamber is deflated, the rubber sleeve returns to the shape of the pipe under its own elasticity, so as to greatly reduce the fitting area between the flexible sleeve and the flow channel, when the water treatment device is installed in a water treatment facility such as a diversion well, the water treatment device only needs to be connected with any one pipe orifice (a water inlet pipe or a water outlet pipe) and does not need to be installed in the well in the whole transverse direction, and the occupied space is extremely small.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
