Description

Technical Field

[0001] The present invention relates to the technical field of anti-seepage pressure reducing valves, in particular to a high-temperature and high-pressure resistant pressure reducing valve. Background Art

[0002] With the gradual improvement of modern water conservancy systems, the anti-seepage performance of pressure reducing valves has gradually improved. A water conservancy pressure reducing valve is a specialized device that automatically reduces the working pressure of a pipeline. It can reduce the higher water pressure in the pipeline upstream of the valve to the required level in the pipeline downstream of the valve. Pressure reducing valves are widely used in hydropower stations, high-rise buildings, areas with excessively high water pressure in urban water supply networks, mines, and other applications to ensure that each water point in the water supply system receives appropriate service water pressure and flow.

[0003] However, the pressure reducing valves currently used in water conservancy projects still have certain drawbacks. The existing pressure reducing valves are directly installed with the input and output pipes, and are therefore affected by garbage and waste entrained in the water flow. When factors such as the external ambient temperature of the pressure reducing valve suddenly change, the interior of the valve body is disturbed by the garbage and waste, which will cause a sudden drop in water pressure. In severe cases, it will cause blockage and rust inside the valve body. The damaged pressure reducing valve will increase the difficulty and risk of replacement due to the interference of local water pressure, and will also be detrimental to the service life of the pressure reducing valve.

[0004] In view of this, a high temperature and high pressure resistant pressure reducing valve is designed to solve the above problems. Summary of the Invention

[0009] In a preferred embodiment, the present invention can be further configured as follows: the material changing mechanism further includes a shaft disposed inside the two anti-overflow rotary discs, and the outer ends of the anti-overflow rotary discs are provided with ring gears; Second bearings are installed at both ends of the shaft; Two symmetrically distributed clamps are provided on the outside of the second bearing, and gaskets are provided in the notches at the top ends of the clamps; The two clamps are adapted to be installed in the pre-installed groove.

[0010] In a preferred example, the present invention can be further configured as follows: the valve main body mechanism also includes a valve body installed in the middle of the two output ends and a valve core arranged in the valve body.

[0011] In a preferred example, the present invention can be further configured as follows: the driving mechanism includes a chassis arranged at the bottom of the valve body, and a motor arranged inside the chassis; Two symmetrically distributed outer frames are installed at the bottom of the valve body; A first bearing is installed at the outer end of the outer frame, and a linkage shaft is arranged in the first bearing; There are two linkage shafts, and the two linkage shafts are connected with transmission lines.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0022] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] A high temperature and high pressure resistant pressure reducing valve provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1:

[0024] Combine Figures 1-13 As shown, the present invention provides a high-temperature and high-pressure resistant pressure reducing valve, including a valve main body mechanism 100, a driving mechanism 200 arranged on the valve main body mechanism 100, two sets of material changing mechanisms 300 arranged on the valve main body mechanism 100, multiple sets of transfer and miscellaneous collection mechanisms 400 arranged in the two sets of material changing mechanisms 300, and two sets of self-blocking mechanisms 500 arranged in the transfer and miscellaneous collection mechanisms 400. The valve main body mechanism 100 is used to control the flow of the water conservancy pipeline, the driving mechanism 200 is used to provide self-replacement kinetic energy for the two sets of material changing mechanisms 300, the material changing mechanism 300 is used to provide a platform for rapid replacement for the multiple sets of transfer and miscellaneous collection mechanisms 400, the multiple sets of transfer and miscellaneous collection mechanisms 400 are used to quickly replace and remove impurities from the valve main body mechanism 100, and the self-blocking mechanism 500 is used to collect garbage and waste accumulated in the transfer and miscellaneous collection mechanism 400 and to dredge the water flow.

[0025] The valve body 100 includes an output end 130 and an input end 140 , each of which is provided with a pre-installed groove 150 , a valve body 110 installed in the middle of the two output ends 130 , and a valve core 120 disposed in the valve body 110 ; The material changing mechanism 300 includes two anti-overflow turntables 310 provided on the outer port of the output end 130 and the inner port of the input end 140, and a plurality of evenly distributed assembly holes 370 are opened inside the anti-overflow turntables 310; The transfer and collection mechanism 400 includes a transfer tube 410 disposed between the two anti-overflow turntables 310, two stabilization tubes 460 disposed within the transfer tube 410, an inner tube 450 disposed in the middle of the inner cavity of the transfer tube 410, and a pressure detector 440 disposed on the transfer tube 410. The detection terminal of the pressure detector 440 is adapted to penetrate the interior of the inner tube 450. A filter element 480 is installed in the middle of the inner tube 450; A pressure relief cover 470 is provided in a stabilization duct 460 near the output end 130; A plug 420 is installed in the hole at the top of the transfer tube 410, and a pitch-adjusting wheel 430 is provided inside the plug 420; The stabilization duct 460 is composed of a sleeve, a rack plate and a gasket. Two sets of self-blocking mechanisms 500 are arranged in the transfer pipe 410 to capture garbage and waste in the water flow at the same time.

[0026] After the pressure reducing valve for water conservancy projects is directly fixed to the pipeline, after long-term use, the sealing gasket between the end pipe of the valve body and the external pipeline will accelerate aging and corrosion due to the interference of garbage, waste and impurities. At the same time, the external environmental factors and temperature of the valve body will cause additional corrosion to the valve body. As the use time increases, the output pressure of this pressure reducing valve will become unstable, and the abnormal pressure will further cause blockage by foreign matter.

[0027] Before using the new pressure reducing valve, the external pipeline needs to be closed, and then the two input ends 140 are connected to the two external pipelines using bolts. After the two sets of anti-overflow rotary discs 310 control the two sets of transfer and collection mechanisms 400 to effectively connect the two sets of output ends 130 and input ends 140, the valve body can provide an effective passage for the external pipeline, and then the valve core 120 is opened. Then, the two adjustable distance wheels 430 in the two transfer and collection mechanisms 400 are adjusted. As the two symmetrically distributed stabilizing tubes 460 are forced to extend outward, the two stabilizing tubes 460 are precisely inserted into the output end 130 and the input end 140. At this time, the passage can provide a sealed cavity for the transfer of water flow. As the two stabilizing tubes 460 extend outward, the two pulled cables 540 pull the first leaf gate 560 and the second leaf gate 570 in the opposite direction to contract. At this time, the sealed cavity can convey the water flow, and the garbage entrained in the water flow can be collected by the filter element 480. After a certain period of use, the two stabilizing ducts 460 that have been reset by the pitch-adjusting rotor 430 will shrink toward the inside of the transfer tube 410. At this time, the two sets of first leaf doors 560 and second leaf doors 570 can block the two stabilizing ducts 460, thereby preventing the backflow and overflow of garbage and waste due to residual pressure. Example 2:

[0028] Combine Figure 3 and Figure 8 As shown, based on embodiment 1, the driving mechanism 200 includes a chassis 210 disposed at the bottom of the valve body 110 and a motor 220 disposed inside the chassis 210; Two symmetrically distributed outer frames 230 are installed at the bottom of the valve body 110; A first bearing 240 is mounted on the outer end of the outer frame 230 , and a linkage shaft 250 is disposed in the first bearing 240 .

[0029] Preferably, the chassis 210 provides effective energy for the motor 220 and controls the start and stop of the chassis 210 through the system. When the motor 220 is started, the system will also measure the real-time water pressure in the inner tube 450 through the pressure detector 440, and at the same time pre-tighten the system to quickly prompt the staff.

[0030] There are two linkage shafts 250 , and the two linkage shafts 250 are connected to each other with a line 260 ; The outer frame 230 is an L-shaped structure as a whole, and is made of stainless steel, and the surface of the outer frame 230 is coated with an anti-rust paint layer; A gear is provided at the bottom of the transmission shaft in the motor 220, and the gear is connected to the middle of the line 260; The linkage shaft 250 is composed of several vertical shafts, a top gear plate and a bottom gear plate, and the bottom gear plate is adapted to be engaged with the tooth opening of the ring gear 320 .

[0031] Preferably, the two outer frames 230 are fixedly installed on the bottom of the valve body 110 by bolts, and the first bearing 240 arranged in the two outer frames 230 can provide sufficient compressive auxiliary bearing pressure for the linkage shaft 250. At this time, the two linkage shafts 250 in the linkage state can drive the combined anti-overflow turntable 310 and the ring gear 320 in an orderly and stable manner. Example 3:

[0032] Combine Figure 3-Figure 7 As shown, based on Example 1, the material changing mechanism 300 further includes a shaft 330 disposed inside the two overflow prevention rotary disks 310, and the outer ends of the overflow prevention rotary disks 310 are provided with ring gears 320; Second bearings 340 are installed at both ends of the shaft 330; Two symmetrically distributed clamps 350 are provided on the outside of the second bearing 340 , and a gasket 360 is provided in the notch at the top of the clamp 350 .

[0033] Preferably, two second bearings 340 are provided at both ends of the shaft 330. When the external pipeline wall is installed, the two anti-overflow turntables 310 without the transfer and collection mechanism 400 can rotate freely along the ports of the output end 130 and the input end 140. At this time, the two idle anti-overflow turntables 310 can be inspected and maintained for the inner walls of the output end 130 and the input end 140 through multiple evenly distributed assembly holes 370.

[0034] The two clamps 350 are adapted to be installed in the pre-installed groove 150; An anti-overflow rubber layer is provided on the end surface of the anti-overflow turntable 310 where the ring gear 320 is provided, and an anti-rust paint layer is coated on the other end surface of the anti-overflow turntable 310.

[0035] Preferably, the anti-overflow turntable 310 is provided with a rubber layer on the end face of the ring tooth 320 adapted to fit the outer end of the output end 130 or the inner end of the input end 140. As the anti-overflow turntable 310 rotates, the rubber layer can prevent the overflow of water in the pipeline under pressure. Example 4:

[0036] Combine Figures 8-13 As shown, in the above embodiment, the self-blocking mechanism 500 includes a truss 510 fixedly installed in the inner tube 450, two insertion rods 520 are provided inside the truss 510, and a horizontal cross bar 550 is installed at the outer end of the truss 510.

[0037] Preferably, the two trusses 510 are fixedly mounted on the inner walls at both ends of the inner tube 450. At this time, the outer ends of the trusses 510 can provide a pressure-bearing support platform for the cross bar 550. At this time, the first leaf door 560 and the second leaf door 570 movably mounted on the cross bar 550 can be controlled by the stabilization catheter 460 through two cables 540, and ultimately the garbage and waste entrained in the water flow can be effectively collected.

[0038] A first leaf door 560 and a second leaf door 570 are movably mounted on the crossbar 550; A cable 540 is installed on each of the first leaf door 560 and the second leaf door 570 . The cable 540 is adapted to pass through the slot inside the truss 510 and bears pressure on the insertion rod 520 . A reinforcing spring 530 is provided between the cable 540 and the raised end plate of the truss 510; The outer end of the cable 540 is mounted on the wall of the stabilization conduit 460 .

[0039] Preferably, the two reinforcing springs 530 are under pressure on the end plates of the truss 510, and a gasket is provided at the end of the cable 540 close to the first leaf door 560 or the second leaf door 570, and the gasket is pressed against the other end of the reinforcing spring 530. As the cable 540 is pulled, the gasket can compress the reinforcing spring 530. After a certain period of use, the two reinforcing springs 530 can prompt the first leaf door 560 and the second leaf door 570 to seal the inner cavity of the stabilization catheter 460, and finally press against the gasket ring. At this time, the stored garbage and waste can be prevented from overflowing.

[0040] The working principle and use process of the present invention: The hydraulic pressure reducing valve is one of the indispensable and important components in the hydraulic pipeline. It is a throttling element with variable local resistance. By changing the throttling area, the flow velocity and kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction; However, the current application of pressure reducing valves has many drawbacks. When the pressure reducing valve is connected to the input and output pipelines, it will be affected by the waste carried by the water flow in the pipeline, and the pressure inside the pressure reducing valve will become abnormal. As the pressure decreases, the valve body will be blocked by foreign matter, causing it to rust and corrode, which will in turn cause problems such as corrosion of the seals, and ultimately cause the pressure reducing valve to leak. After the two input ends 140 of the device are connected to the input and output pipes, the two transfer and collection mechanisms 400 disposed in the two sets of overflow prevention turntables 310 will precisely dock the two output ends 130 and the input end 140. The pitch-adjusting wheel 430 is then adjusted until the gear at its bottom drives the two stabilizing conduits 460 to extend in opposite directions at the same speed. Finally, the two stabilizing conduits 460 can respectively penetrate the inner cavities of the output end 130 and the input end 140. At this point, the new valve can provide an effective transfer path for the water conservancy pipeline. When the valve core 120 rotates to open the valve body 110, the two transfer and collection mechanisms 400 in the passage can effectively collect garbage and waste in the water flow of the pipeline. As the two transfer and collection mechanisms 400 capture and collect garbage and waste in the water flow within a certain period of time, when the water pressure in the inner cavity of the inner tube 450 is disturbed by the garbage and waste and causes the pressure to drop, the pressure detector 440 extends into the inner cavity of the inner tube 450 to measure the pressure in real time. The sudden pressure drop data is uploaded to the system to obtain an effective pre-tightening prompt. Then, the worker controls the pitch wheel 430 to rotate in the opposite direction until the two stabilization tubes 460 retract inward and return to the inner cavity of the transfer tube 410. As the two stabilizing tubes 460 are retracted toward the inner cavity of the transfer tube 410, the two pull cables 540 provided on the wall of the stabilizing tube 460 are relaxed. At this time, the first leaf door 560 and the second leaf door 570, pushed by the strong pressure of the two reinforcing springs 530, are closed toward the wall of the stabilizing tube 460 until a circular structure is formed. Finally, the first leaf door 560 and the second leaf door 570 in the circular structure can effectively fit the gasket pre-pressed on the wall of the stabilizing tube 460. At this time, the waste collected during the timed infusion can be uniformly retracted by the sealing structure formed by the two sets of first leaf doors 560, the second leaf door 570 and the transfer tube 410. By controlling the motor 220 through the system, the transmission shaft in the motor 220 will drive the line 260, and the two ends of the line 260 can jointly drive the two linkage shafts 250. As the two linkage shafts 250 rotate at the same speed and cooperate with the pressure of the transfer and collection mechanism 400, the two anti-overflow turntables 310 can be driven to rotate, and a group of transfer and collection mechanisms 400 storing garbage and waste can be transferred out. The two anti-overflow turntables 310 fit the external port of the output end 130 and the internal port of the input end 140, thereby effectively reducing the overflow of water, and the remaining transfer and collection mechanisms 400 can be selectively installed at the assembly positions of the output end 130 and the input end 140. Then, the distance adjustment wheel 430 in the newly installed group of transfer and collection mechanisms 400 can be adjusted again until the two stabilization tubes 460 are reinserted into the output end 130 and the input end 140. At this point, the device can be highly adaptable to different water pipelines.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
