Description

Technical Field

[0001] The invention belongs to the technical field of control valves, and in particular relates to an industrial water-saving control valve. Background Art

[0002] Control valves are control components in a type of fluid delivery system, which mainly play the role of diversion, interception, regulation, interception, diversion or pressure relief in the fluid delivery system. Among them, industrial water control valves are a type of control valve installed in industrial water delivery systems. With the continuous development of automation technology, some industrial water control valves are gradually controlled by automation technology. Industrial water control valves using automated control can accurately and automatically control the opening and closing status of the control valves.

[0003] However, no matter it is a manually controlled industrial water control valve or an industrial water control valve controlled by automation technology, in the actual assembly process, it is mainly assembled in the fluid delivery pipeline by combining a flange and a sealing ring. Although this method can seal and limit the industrial water control valve, as the use time increases and the sealing ring ages, the sealing effect of the industrial water control valve connection position is poor and water leakage occurs, resulting in a waste of water resources after long-term use of the industrial water control valve, making the water-saving effect of the industrial water control valve poor.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The object of the present invention is to provide an industrial water-saving control valve, which can reduce the waste of water resources caused by long-term use of the industrial water control valve and improve the water-saving effect of the industrial water control valve.

[0006] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

[0007] An industrial water-saving control valve comprises a valve pipe, a connecting flange, a self-expanding sealing mechanism and an early warning auxiliary sealing mechanism.

[0008] Connecting flanges are integrally formed on both sides of the valve pipe.

[0009] A pair of the self-inflating sealing mechanisms are symmetrically assembled at both ends of the valve tube, and the self-inflating sealing mechanism includes an assembled inner tube, the outer side wall of the assembled inner tube is fixedly connected to the inner wall of the valve tube, and an annular air expansion chamber is provided on one side of the assembled inner tube outside the valve tube, a self-inflating sealing ring is fixedly assembled in the annular air expansion chamber, and a return air duct is provided in the assembled inner tube, and the return air duct is communicated with the self-inflating sealing ring.

[0010] The early warning auxiliary sealing mechanism is assembled on the outside of the assembly inner tube, and the early warning auxiliary sealing mechanism includes an auxiliary sealing ring, and the auxiliary sealing ring is snap-fitted and assembled on the side of the connecting flange away from the valve tube, and a plurality of evenly distributed early warning strips are fixedly assembled in the auxiliary sealing ring, and a plurality of groups of evenly distributed moisture-deflecting strips are assembled on the side of the auxiliary sealing ring away from the connecting flange, and the plurality of groups of moisture-deflecting strips are staggeredly distributed with the early warning strips.

[0011] In one or more embodiments of the present invention, the connecting flange is provided with a plurality of evenly distributed assembly through holes. The assembly through holes are provided to facilitate assembly and connection between the connecting flange and the external pipe. The connecting flange is provided with an annular compression gas cavity on the side close to and away from the valve pipe. The annular compression gas cavity supports and limits the compression ring plate, and the gas in the annular compression gas cavity can be transported to the annular gas expansion cavity along the gas transport channel by compressing the compression ring plate.

[0012] In one or more embodiments of the present invention, a plurality of evenly distributed delivery air channels are provided on one side of the connecting flange close to the assembly inner tube, and the two ends of the delivery air channel are respectively connected to the annular compression air cavity and the return air channel, and the delivery air channel and the return air channel cooperate to form a gas delivery channel. The gas delivery channel serves to connect the annular compression air cavity and the annular gas expansion cavity, and the self-expanding sealing ring is ejected under the action of the gas by delivering the gas in the annular compression air cavity to the annular gas expansion cavity, thereby improving the sealing effect of the self-expanding sealing ring on the external pipe by the self-expanding sealing ring contacting with the inner wall of the external pipe.

[0013] In one or more embodiments of the present invention, a compression ring plate is slidably mounted in the annular compression gas cavity, and the compression ring plate is slidably and sealably mounted in the annular compression gas cavity. The annular compression gas cavity is spatially compressed by controlling the movement of the compression ring plate, so that the gas in the annular compression gas cavity is transported to the annular gas expansion cavity along the gas delivery channel. A return spring is fixedly connected to one side of the compression ring plate located in the annular compression gas cavity. The return spring supports and limits the compression ring plate, and the compression ring plate is supported and reset by the contraction and reset of the return spring.

[0014] In one or more embodiments of the present invention, the self-expanding sealing ring is filled with an expansion filler. The expansion filler expands when it encounters water, so that the self-expanding sealing ring expands, thereby further improving the sealing and limiting effect of the self-expanding sealing ring. A conductive pad is fixedly connected to the side of the self-expanding sealing ring away from the connecting flange, and the conductive pad is connected to the expansion filler. By providing the conductive pad, the water leaking from the outside can contact the expansion filler under the action of the conductive pad.

[0015] In one or more embodiments of the present invention, a plurality of evenly distributed assembly avoidance holes are provided on the outer side of the auxiliary sealing ring, and the plurality of assembly avoidance holes are arranged one by one in correspondence with the assembly through holes. This reduces the interference of the connecting flange with the assembly through holes. At the same time, the assembly bolts can be passed through the assembly avoidance holes so that the assembly bolts can assist in positioning the auxiliary sealing ring, thereby ensuring the assembly stability of the auxiliary sealing ring.

[0016] In one or more embodiments of the present invention, a limiting ring is integrally formed on the side of the auxiliary sealing ring facing away from the connecting flange. It is convenient to allow the compression ring to control the compression of the compression ring plate through the mutual extrusion of the external pipeline and the limiting ring, thereby playing a role in compression control of the annular compression air cavity. A compression ring is integrally formed on the side of the auxiliary sealing ring close to the connecting flange, and the compression ring is snap-fitted and assembled in the annular compression air cavity. The snap-fitting of the compression ring and the annular compression air cavity ensures the stability of the assembly of the auxiliary sealing ring. At the same time, the annular compression air cavity can be compressed by the interaction between the compression ring and the compression ring plate.

[0017] In one or more embodiments of the present invention, a plurality of evenly distributed transparent waterproof pads are fixedly mounted on the outer side of the auxiliary sealing ring, and the plurality of transparent waterproof pads are arranged corresponding to the warning strip. The plurality of transparent waterproof pads provide waterproof protection for the warning strip, thereby reducing the interference of external water vapor on the warning strip, and ensuring the reliability of the warning strip in detecting and judging the leakage state of the auxiliary sealing ring.

[0018] In one or more embodiments of the present invention, a plurality of the warning strips are filled with color-changing fillers, and the color-changing fillers are in contact with the moisture-conducting strips. The color-changing fillers change color when in contact with water to provide a warning to determine whether there is a leak in the pipeline, which provides convenience for the subsequent inspection and maintenance of the water-saving control valve.

[0019] In one or more embodiments of the present invention, one end of the moisture conducting strip located in the limiting ring is fixedly connected to a ventilated moisture conducting pad, and the side of the ventilated moisture conducting pad away from the moisture conducting strip is located outside the limiting ring. The moisture conducting strip is in contact with the external pipe through the ventilated moisture conducting pad, so that the water leaked from the outside is easily transported to the warning strip along the ventilated moisture conducting pad and the moisture conducting strip.

[0020] Compared with the prior art, the industrial water-saving control valve disclosed in the present invention significantly improves the efficiency of connecting and sealing the industrial water control valve by providing a self-expanding sealing mechanism and a warning auxiliary sealing mechanism, greatly reduces the risk of leakage of the industrial water control valve during use, and improves the water-saving effect of the industrial water control valve.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, an industrial water-saving control valve in one embodiment of the present invention includes: a valve pipe 1, a connecting flange 101, a self-expanding sealing mechanism 2, and an early warning auxiliary sealing mechanism 3.

[0034] like Figure 1 As shown, both sides of the valve pipe 1 are integrally formed with connecting flanges 101. The valve pipe 1 is assembled and connected with an external pipeline by assembling and fixing the connecting flanges 101.

[0035] Specifically, a plurality of evenly distributed assembly through holes are provided on the connection flange 101. The assembly through holes facilitate the assembly connection between the connection flange 101 and the external pipe.

[0036] like Figures 2 to 3 As shown, a pair of self-expanding sealing mechanisms 2 are symmetrically assembled at both ends of the valve tube 1, and the self-expanding sealing mechanism 2 includes an assembled inner tube 201, and the outer wall of the assembled inner tube 201 is fixedly connected to the inner wall of the valve tube 1. The assembled inner tube 201 is used to limit the connection between the valve tube 1 and the external pipeline.

[0037] like Figures 2 to 3 As shown, an annular air expansion chamber 202 is provided on one side of the assembly inner tube 201 outside the valve tube 1. The annular air expansion chamber 202 serves to store and limit the self-expanding sealing ring 203, and the self-expanding sealing ring 203 is ejected by supplying gas to the annular air expansion chamber 202.

[0038] like Figures 2 to 3As shown, a self-expanding sealing ring 203 is fixedly installed in the annular air expansion chamber 202. The self-expanding sealing ring 203 is pressed and matched with the assembled inner tube 201 and the external pipeline to perform auxiliary sealing on the assembled inner tube 201 and the external pipeline.

[0039] like Figures 2 to 3 As shown, a return air passage 204 is provided in the assembly inner tube 201, and the return air passage 204 is connected to the self-expanding sealing ring 203. Gas is delivered to the annular gas expansion chamber 202 through the return air passage 204, so as to facilitate the ejection control of the self-expanding sealing ring 203.

[0040] like Figures 2 to 3 As shown, a plurality of evenly distributed delivery air passages 206 are provided on one side of the connecting flange 101 close to the assembly inner tube 201, and the two ends of the delivery air passage 206 are respectively connected to the annular compressed air cavity 205 and the return air passage 204, and the delivery air passage 206 cooperates with the return air passage 204 to form a gas delivery channel. The gas delivery channel serves to connect the annular compressed air cavity 205 with the annular gas expansion cavity 202, and the self-expanding sealing ring 203 is ejected under the action of the gas by delivering the gas in the annular compressed air cavity 205 to the annular gas expansion cavity 202, thereby improving the sealing effect of the self-expanding sealing ring 203 on the external pipe by the way that the self-expanding sealing ring 203 conflicts with the inner wall of the external pipe.

[0041] like Figures 2 to 3 As shown, a compression ring plate 207 is slidably mounted in the annular compression gas cavity 205, and the compression ring plate 207 is slidably and sealingly mounted in the annular compression gas cavity 205. The annular compression gas cavity 205 is spatially compressed by controlling the movement of the compression ring plate 207, so that the gas in the annular compression gas cavity 205 is transported to the annular gas expansion cavity 202 along the gas transport flow channel.

[0042] like Figures 2 to 3 As shown, the connecting flange 101 is provided with an annular compressed air cavity 205 on the side close to and away from the valve pipe 1. The annular compressed air cavity 205 supports and limits the compression ring plate 207, and the gas in the annular compressed air cavity 205 can be transported to the annular gas expansion cavity 202 along the gas transport channel by compressing the compression ring plate 207.

[0043] like Figures 2 to 3 As shown, a return spring 208 is fixedly connected to one side of the compression ring plate 207 located in the annular compression air cavity 205. The return spring 208 supports and limits the compression ring plate 207, and the compression ring plate 207 is supported and reset by the contraction and reset of the return spring 208.

[0044] like Figures 2 to 3As shown, the self-expanding sealing ring 203 is filled with an expansion filler 209. The expansion filler 209 expands when it encounters water, so that the self-expanding sealing ring 203 expands, thereby further improving the sealing and limiting effect of the self-expanding sealing ring 203.

[0045] Specifically, the expansion filler 209 is a mixture of an inorganic water-absorbing material and a high-viscosity resin. The expansion filler 209 absorbs water and expands, thereby causing the self-expanding sealing ring 203 to expand, thereby adjusting the sealing effect of the self-expanding sealing ring 203 .

[0046] like Figures 2 to 3 As shown, a conductive pad 210 is fixedly connected to the side of the self-expanding sealing ring 203 away from the connecting flange 101, and the conductive pad 210 is connected to the expansion filler 209. By providing the conductive pad 210, the water leaking from the outside can contact the expansion filler 209 under the action of the conductive pad 210.

[0047] like Figures 4 to 8 As shown, the early warning auxiliary sealing mechanism 3 is assembled on the outside of the assembly inner tube 201, and the early warning auxiliary sealing mechanism 3 includes an auxiliary sealing ring 301, which is engaged and assembled on the side of the connecting flange 101 away from the valve tube 1. The connecting flange 101 is connected and sealed with the external pipeline through the auxiliary sealing ring 301.

[0048] like Figures 7 and 8 As shown, multiple evenly distributed warning strips 302 are fixedly installed in the auxiliary sealing ring 301. The multiple warning strips 302 absorb water and change color to observe whether there is water leakage at the connection position of the auxiliary sealing ring 301, which provides convenience for the subsequent maintenance and replacement of the auxiliary sealing ring 301.

[0049] like Figures 7 and 8 As shown, multiple warning strips 302 are filled with color-changing fillers 307, and the color-changing fillers 307 are in contact with the moisture-conducting strips 303. The color-changing fillers 307 change color when in contact with water to provide early warning judgment on whether there is a leakage in the pipeline, which provides convenience for the subsequent inspection and maintenance of the water-saving control valve.

[0050] Preferably, the color-changing filler 307 is anhydrous cobalt chloride.

[0051] like Figures 2 to 8 As shown, the auxiliary sealing ring 301 is equipped with multiple groups of evenly distributed moisture guide strips 303 on the side away from the connecting flange 101, and the multiple groups of moisture guide strips 303 are staggered with the warning strips 302. The moisture guide strips 303 conduct water vapor to the warning strips 302 and the ventilation moisture guide pad 308.

[0052] Specifically, a plurality of evenly distributed assembly avoidance holes are provided on the outer side of the auxiliary sealing ring 301, and the plurality of assembly avoidance holes are arranged one by one in correspondence with the assembly through holes. This reduces the interference of the connecting flange 101 with the assembly through holes. At the same time, the assembly bolts can be passed through the assembly avoidance holes so that the assembly bolts can assist in positioning the auxiliary sealing ring 301, thereby ensuring the assembly stability of the auxiliary sealing ring 301.

[0053] like Figures 4 to 6 As shown, the auxiliary sealing ring 301 is integrally formed with a limiting ring 304 on one side away from the connecting flange 101. The compression ring 305 can compress the compression ring plate 207 through the mutual extrusion of the external pipe and the limiting ring 304, thereby playing a role in compressing the annular compression air cavity 205.

[0054] like Figures 4 to 6 As shown, a compression ring 305 is integrally formed on one side of the auxiliary sealing ring 301 close to the connecting flange 101, and the compression ring 305 is engaged and assembled in the annular compression air cavity 205. The engagement of the compression ring 305 with the annular compression air cavity 205 ensures the stability of the assembly of the auxiliary sealing ring 301. At the same time, the annular compression air cavity 205 can be compressed by the interaction between the compression ring 305 and the compression ring plate 207.

[0055] like Figures 7 and 8 As shown, a plurality of evenly distributed transparent waterproof pads 306 are fixedly mounted on the outside of the auxiliary sealing ring 301, and the plurality of transparent waterproof pads 306 are arranged corresponding to the warning strip 302. The plurality of transparent waterproof pads 306 provide waterproof protection for the warning strip 302, reduce the interference of external water vapor on the warning strip 302, and ensure the reliability of the warning strip 302 in detecting and judging the water leakage state of the auxiliary sealing ring 301.

[0056] like Figures 2 to 5 As shown, one end of the moisture conducting strip 303 located in the limiting ring 304 is fixedly connected to a ventilated moisture conducting pad 308, and the side of the ventilated moisture conducting pad 308 away from the moisture conducting strip 303 is located outside the limiting ring 304. The ventilated moisture conducting pad 308 makes contact with the external pipe, so that the water leaked from the outside is easily transported to the warning strip 302 along the ventilated moisture conducting pad 308 and the moisture conducting strip 303.

[0057] During specific use, when the valve tube 1 needs to be assembled, the external pipe is put on the outside of the assembly inner pipe 201, and a plurality of assembly bolts are passed through the assembly through holes and the assembly avoidance holes to connect the connecting flange 101 and the external pipe. During the connection process, the external pipe squeezes the limit ring 304.

[0058] When the external pipe squeezes the limit ring 304, the compression ring 305 squeezes the compression ring plate 207 under the action of external force. At this time, the air in the annular compression air chamber 205 can be transported to the annular air expansion chamber 202 along the delivery air channel 206 and the return air channel 204, so that the self-expanding sealing ring 203 is squeezed out under the action of the gas, thereby auxiliary sealing the assembly inner tube 201 and the external pipe by squeezing the self-expanding sealing ring 203.

[0059] When water leaks at the connection between the external pipe and the assembled inner pipe 201 during use, the leaked water can contact the expansion filler 209 along the conductive pad 210, and the expansion filler 209 absorbs water and expands to improve the auxiliary sealing effect of the self-expanding sealing ring 203.

[0060] In addition, when water leakage still exists, the leaked water flow can be transported to the early warning strip 302 along the ventilation and moisture-conducting pad 308 and the moisture-conducting strip 303, and the auxiliary sealing ring 301 can be observed and judged whether there is a water leakage state by the way that the early warning strip 302 absorbs water and changes color, thereby simplifying the subsequent inspection and replacement process of the auxiliary sealing ring 301, avoiding the valve tube 1 from leaking due to the wear of the auxiliary sealing ring 301 during use, and improving the conduction stability and water-saving effect of the valve tube 1.

[0061] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0062] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
