[0026] Reference Figure 1-Figure 3 , which is an embodiment of the present utility model, provides an anti-seepage pressure reducing valve for a water conservancy project channel, including a main unit 100, a filter unit 200 and a regulating unit 300.

[0027] The main unit 100 includes a pressure reducing valve body 101 and a water inlet pipe 102 matched with the pressure reducing valve body 101. A water outlet pipe 103 is fixedly installed on one side of the pressure reducing valve body 101 away from the water inlet pipe 102 for conveying water.

[0028] The filter unit 200 includes a mounting groove 201 provided at the top of the water inlet pipe 102, the inner cavity of the mounting groove 201 is vertically slidably connected to the mounting frame 202, the inner cavity of the mounting frame 202 is fixedly installed with a filter screen 203, the top of the water inlet pipe 102 is fixedly installed with a support frame 204, plug blocks 205 are symmetrically installed on both sides of the support frame 204, and two groups of plug blocks 205 are provided with a threaded groove 208 on the side away from the mounting frame 202, sockets 206 are symmetrically installed on both sides of the water inlet pipe 102, and the sockets 206 and the plug blocks 205 are snap-fitted, the outer walls of the two groups of sockets 206 are provided with bolts 207, and the bolts 207 are threadedly connected to the threaded grooves 208, the water first flows smoothly into the interior of the pressure reducing valve body 101 through the water inlet pipe 102, and in this process, the water will encounter the fine filtration of the filter screen 203. It is used to effectively remove all kinds of impurities and particulate matter carried in the water flow. Subsequently, the purified water continues to flow and is finally discharged from the outlet pipe 103 of the pressure reducing valve body 101, ensuring the cleanliness and smoothness of the output water quality. If the filter 203 needs to be maintained and cleaned, just gently rotate the bolt 207 to disengage it from the threaded groove 208 that fits tightly with the plug 205. This step unlocks the fixed state of the mounting frame 202. Subsequently, using the support frame 204 as an aid, the mounting frame 202 together with the filter 203 can be easily and smoothly pulled out from the mounting groove 201 on the pressure reducing valve body 101. In this way, the filter can be conveniently and thoroughly cleaned and maintained, effectively avoiding the problem of valve body blockage caused by impurity accumulation, thereby ensuring the continuous and efficient operation of the pressure reducing valve body 101.

[0029] The two sets of sockets 206 are symmetrically provided with through grooves on one side away from the water inlet pipe 102 , and the through grooves are slidably connected to the bolts 207 . The bolts 207 pass through the through grooves provided in the sockets 206 and are threadedly connected to the thread grooves 208 of the insert block 205 .

[0030] The regulating unit 300 includes an exhaust pipe 301 fixedly mounted on one side of the top end of the pressure reducing valve body 101, and the exhaust pipe 301 is communicated with the pressure reducing valve body 101, a limit ring 302 is fixedly mounted on the inner cavity of the exhaust pipe 301, and a through hole 303 is opened on one side of the limit ring 302, a sealing plug 304 is provided on one side of the limit ring 302, a telescopic spring 305 is fixedly mounted on one side of the sealing plug 304, and the other end of the telescopic spring 305 is fixedly connected to the inner wall of the exhaust pipe 301, and the exhaust pipe An air outlet 306 is provided on one side of 301, through which the high-pressure gas in the pressure reducing valve body 101 can be discharged. When the high-pressure gas enters the exhaust pipe 301, when the pressure of the high-pressure gas is greater than the elastic force of the telescopic spring 305, the high-pressure gas will push the sealing plug 304, so that the sealing plug 304 is separated from the limiting ring 302, so that the high-pressure gas is discharged from the air outlet 306 of the limiting ring 302 through the through hole 303 of the limiting ring 302, thereby avoiding excessive pressure inside the pressure reducing valve body 101.

[0031] The inner wall of the exhaust pipe 301 is symmetrically provided with sliding grooves 308, and the inner cavities of the two sets of sliding grooves 308 are slidably connected with sliders 307, and the opposite surfaces of the two sets of sliders 307 are fixedly connected to the outer wall of the sealing plug 304. The sliders 307 and the sliding grooves 308 cooperate to ensure that the sealing plug 304 is in a stable state when moving.

[0032] A sealing block 104 is fixedly installed on one end of the water inlet pipe 102 and the water outlet pipe 103 away from the pressure reducing valve body 101, and an elastic water blocking ring 105 is fixedly installed on the inner wall of the sealing block 104. The elastic water blocking ring 105 prevents water leakage at the connection between the sealing block 104 and the external pipeline.

[0033] The bottom end of the pressure reducing valve body 101 is threadedly connected to a sealing cover 106 . The sealing cover 106 is made of stainless steel. The threaded connection design allows the sealing cover 106 to be easily disassembled when needed, making it easy to maintain and inspect the interior of the pressure reducing valve body 101 .

[0034] During use, the external pipe is placed inside the sealing block 104, and the elastic water-blocking ring 105 prevents water from leaking at the connection between the sealing block 104 and the external pipe. The water first flows smoothly into the interior of the pressure reducing valve body 101 through the water inlet pipe 102. During this process, the water will encounter the fine filtering effect of the filter 203, which effectively removes various impurities and particulate matter carried in the water flow. Subsequently, the purified water continues to flow and is finally discharged from the water outlet pipe 103 of the pressure reducing valve body 101, ensuring the cleanliness and smoothness of the output water quality. If the filter 203 needs to be adjusted, For maintenance and cleaning, it is only necessary to gently rotate the bolt 207 to disengage it from the threaded groove 208 that is tightly fitted with the insert 205. This step unlocks the fixed state of the mounting frame 202. Subsequently, using the support frame 204 as an aid, the mounting frame 202 together with the filter screen 203 can be easily and smoothly pulled out from the mounting groove 201 on the pressure reducing valve body 101. In this way, the filter screen can be conveniently and thoroughly cleaned and maintained, effectively avoiding the problem of valve body blockage caused by impurity accumulation, thereby ensuring the continuous and efficient operation of the pressure reducing valve body 101.
