Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure regulating valves, and more particularly to intelligent pressure regulating valves. Background Technology
[0002] A pressure regulating valve is a device used to regulate fluid pressure. It can adjust the fluid pressure from a higher value to a stable lower value that meets the usage requirements, so as to ensure the safe and stable operation of the fluid system. In the production processes of chemical, petroleum, metallurgical and other industries, many process steps require precise control of fluid pressure to ensure the stability of product quality and the safety of the production process.
[0003] When fluid enters the pressure regulating valve, the inlet pressure acts on the valve core or diaphragm. If the inlet pressure is higher than the set outlet pressure, the spring force will push the valve core to move, reducing the valve opening and thus limiting the fluid flow rate, causing the outlet pressure to drop to the set value. If the inlet pressure is lower than the set value, the spring force will increase the valve core opening, increasing the fluid flow rate and thus increasing the outlet pressure. The pressure regulating valve can maintain the outlet pressure stable within the set range.
[0004] When installing the pressure regulating valve and the return water pilot valve, the operator needs to spend a lot of time installing them, which increases the installation time. When the pressure regulating valve or the return water pilot valve malfunctions and needs to be repaired or replaced, the operator cannot quickly separate the pressure regulating valve and the return water pilot valve, which increases the difficulty of the work. Utility Model Content

A locking assembly is provided on one side of the connecting pipe, and locking grooves are provided on both sides of the connecting pipe. A locking groove is provided on one side of the locking groove. A locking block is provided inside the locking groove. The locking block slides inside the locking groove. A sliding rod is fixedly connected to the outside of the locking block and passes through the connecting pipe. The sliding rod slides inside the locking groove. A limit plate is fixedly connected to the other side of the sliding rod. A spring is fixedly connected to one side of the locking groove. The other side of the spring is fixedly connected to the locking block. A return water pilot valve is provided on one side of the connecting pipe. An annular buckle is fixedly connected to the outside of the return water pilot valve. An annular buckle is provided above the annular buckle. The annular buckle slides on the outside of the return water pilot valve.
[0007] Preferably, a fixed arc plate is provided inside the connecting pipe, and a spring three is fixedly connected above the fixed arc plate. A sealing ring is provided on the other side of the spring three, and one side of the annular buckle abuts against the sealing ring.
[0008] Preferably, the pressure regulating valve body has an adjustment knob on the top and a diaphragm chamber inside the valve body on the side of the connecting pipe. A threaded rod is provided below the adjustment knob and passes through the pressure regulating valve body into the diaphragm chamber.
[0009] Preferably, a push plate is provided below the threaded rod, a support seat is provided inside the diaphragm air chamber, a pressure regulating spring is fixedly connected to one side of the push plate, the other side of the pressure regulating spring is fixedly connected to the bottom of the support seat, and an exhaust hole is provided on one side of the diaphragm air chamber.

[0011] Preferably, the diaphragm body has an overflow valve seat inside, an overflow hole is provided above the overflow valve seat, and a valve core is provided below the overflow valve seat, with the valve core passing through the connecting pipe.
[0012] Preferably, an air inlet valve is provided below the connecting pipe, and a return spring is fixedly connected above the air inlet valve, with the return spring sleeved on the valve core.
[0013] The beneficial effects of this utility model are as follows: Through ingenious structural design, a pair of locking blocks are pressed together by a ring buckle, causing the locking blocks to push the sliding rod to slide inside the second locking groove, compressing the fourth spring. When the first ring buckle reaches the appropriate position, the fourth spring pushes the locking block to reset, thus fixing the first ring buckle. When the first ring buckle reaches the locked position, the locking blocks with the same tilt angle are tightly fitted with the first ring buckle. Through the action of the fourth spring, the locking blocks and the first ring buckle are tightly abutted, thereby connecting the return water pilot valve to the connecting pipe. By pushing the return water pilot valve again, the second ring buckle slides. When the second ring buckle slides to the position abutting the first ring buckle, it presses the locking block into the first locking groove, thereby pulling the return water pilot valve out of the connecting pipe, facilitating the disassembly and installation of the return water pilot valve and the connecting pipe.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-5This utility model provides an embodiment of an intelligent pressure regulating valve, including a connecting pipe 101, a locking block 105, and a locking assembly. A locking assembly is provided on one side of the connecting pipe 101, and locking grooves 103 are formed on both sides of the connecting pipe 101. A second locking groove 104 is formed on one side of the first locking groove 103. A locking block 105 is provided inside the first locking groove 103 and slides within it. A sliding rod 106 is fixedly connected to the outside of the locking block 105 and passes through the connecting pipe 101. The sliding rod 106... The inner sliding part of slot 2 104 is fixedly connected to a limit plate 107 on the other side of sliding rod 106. A spring 4 108 is fixedly connected to one side of slot 2 104, and the other side of spring 4 108 is fixedly connected to a locking block 105. A return water pilot valve 109 is provided on one side of connecting pipe 101. An annular buckle 1 110 is fixedly connected to the outside of return water pilot valve 109. An annular buckle 2 111 is provided above annular buckle 110. Annular buckle 2 111 slides on the outside of return water pilot valve 109. By connecting one end of return water pilot valve 109 to the connecting pipe... Align pipe 101, push the return water pilot valve 109 into the interior of the connecting pipe 101, and the annular latch 110 compresses the locking block 105, causing the locking block 105 to push the sliding rod 106 to slide inside the locking groove 104, compressing the spring 108. When the annular latch 110 reaches the appropriate position, the spring 108 pushes the locking block 105 to reset, and the resetting of the locking block 105 fixes the annular latch 110. When the annular latch 110 reaches the locked position, the locking block 105 and the annular latch 110 are at the same tilt angle. 10. The spring 108 causes the locking block 105 to abut tightly against the annular buckle 110, thereby connecting the return water pilot valve 109 to the connecting pipe 101. By pushing the return water pilot valve 109 again, the annular buckle 111 slides. When the annular buckle 111 slides to the position where it abuts against the annular buckle 110, it presses the locking block 105 into the groove 103, thereby pulling the return water pilot valve 109 out of the connecting pipe 101, which facilitates the disassembly and installation of the return water pilot valve 109 and the connecting pipe 101.
[0022] Please see Figures 1-3In this embodiment, a fixed arc plate 201 is provided inside the connecting pipe 101. A spring 202 is fixedly connected above the fixed arc plate 201. A sealing ring 203 is provided on the other side of the spring 202, and one side of the annular buckle 110 abuts against the sealing ring 203. When the return water pilot valve 109 is connected to the connecting pipe 101, the sealing ring 203 is squeezed. When the return water pilot valve 109 is installed in the appropriate position, the spring 202 tightly abuts the sealing ring 203 against the annular buckle 110, which can enhance the connection. The pressure regulating valve body 302 has an adjustment knob 301 on its top and is located on one side of the connecting pipe 101. The pressure regulating valve body 302 has a diaphragm chamber 303 inside. A threaded rod 304 is located below the adjustment knob 301 and passes through the pressure regulating valve body 302 to the inside of the diaphragm chamber 303. The output pressure of the pressure regulating valve body 302 can be easily changed by manually rotating the adjustment knob 301. Rotating the adjustment knob 301 clockwise increases the output pressure, while rotating it counterclockwise decreases the output pressure.
[0023] Please see Figures 1-3 In this embodiment, a push plate 305 is provided below the threaded rod 304, and a support base 306 is provided inside the diaphragm air chamber 303. A pressure regulating spring 307 is fixedly connected to one side of the push plate 305, and the other side of the pressure regulating spring 307 is fixedly connected to the bottom of the support base 306. An exhaust hole 308 is provided on one side of the diaphragm air chamber 303, and a diaphragm body 309 is provided at the bottom of the diaphragm air chamber 303. A pressure regulating spring 401 is fixedly connected to one side of the support base 306, and one side of the pressure regulating spring 401 is fixedly connected to the diaphragm body 309. An overflow valve seat 402 is provided inside the diaphragm body 309. An overflow hole is opened above the overflow valve seat 402, and a valve core 403 is provided below the overflow valve seat 402. The valve core 403 passes through the connecting pipe 101. An air inlet valve 404 is located below the valve 101. A return spring 405 is fixedly connected above the air inlet valve 404 and is sleeved on the valve core 403. By pushing the plate 305 downward, pressure is generated on the first pressure regulating spring 307 and the second pressure regulating spring 401, thereby applying downward pressure to the diaphragm body 309. When the pressure below the diaphragm body 309 is greater than the set pressure of the first pressure regulating spring 307 and the second pressure regulating spring 401, the diaphragm body 309 moves upward, and the valve core 403 moves upward under the action of the return spring 405, reducing the opening of the air inlet valve 404 and lowering the output pressure. When the pressure below the diaphragm body 309 is less than the set pressure, the body moves downward, and the valve core 403 moves downward, increasing the opening of the air inlet valve 404 and increasing the output pressure. When the output pressure is too high, some fluid can be discharged through the overflow hole and the exhaust hole 308.
[0024] During operation, the annular latch 110 presses against the locking block 105, causing the locking block 105 to push the sliding rod 106 to slide inside the locking groove 104, compressing the spring 108. When the annular latch 110 reaches the appropriate position, the spring 108 pushes the locking block 105 back to its original position, thus fixing the annular latch 110 in place. When the annular latch 110 reaches the locked position, the locking block 105, with the same tilt angle, is tightly fitted to the annular latch 110, and the spring 108... The locking block 105 abuts tightly against the annular buckle 110, thereby connecting the return water pilot valve 109 to the connecting pipe 101. By pushing the return water pilot valve 109 again, the annular buckle 111 slides. When the annular buckle 111 slides to the position abutting against the annular buckle 110, it presses the locking block 105 into the groove 103, thereby pulling the return water pilot valve 109 out of the connecting pipe 101. This facilitates the disassembly and installation of the return water pilot valve 109 and the connecting pipe 101. When pipe 101 is connected, it compresses the sealing ring 203. After the return water pilot valve 109 is installed in the appropriate position, the sealing ring 203 and the annular buckle 110 are tightly pressed together by the action of spring 3 202, which can enhance the sealing performance of the connection. The output pressure of the pressure regulating valve body 302 can be easily changed by manually rotating the adjusting knob 301. Rotating the adjusting knob 301 clockwise increases the output pressure, and rotating it counterclockwise decreases the output pressure. The downward movement of the push plate 305 adjusts the pressure regulating spring 1 307 and pressure regulating spring 2 4. Pressure is generated, which applies downward pressure to the diaphragm body 309. When the pressure below the diaphragm body 309 is greater than the set pressure of the first adjusting spring 307 and the second adjusting spring 401, the diaphragm body 309 moves upward, and the valve core 403 moves upward under the action of the return spring 405, reducing the opening of the inlet valve port 404 and lowering the output pressure. When the pressure below the diaphragm body 309 is less than the set pressure, the diaphragm body 309 moves downward, and the valve core 403 moves downward, increasing the opening of the inlet valve port 404 and increasing the output pressure. When the output pressure is too high, some fluid can be discharged through the overflow port and the exhaust port 308.
[0025] Through the above steps, the annular latch 110 compresses the locking block 105, causing the locking block 105 to push the sliding rod 106 to slide inside the locking groove 104, compressing the spring 108. When the annular latch 110 reaches the appropriate position, the spring 108 pushes the locking block 105 to reset, thus fixing the annular latch 110. When the annular latch 110 reaches the locked position, the locking block 105 with the same tilt angle is tightly fitted with the annular latch 110, and the spring... The function of the fourth 108 is that the locking block 105 and the annular buckle 110 abut tightly, thereby connecting the return water pilot valve 109 to the connecting pipe 101. By pushing the return water pilot valve 109 again, the annular buckle 2 111 slides. When the annular buckle 2 111 slides to the position where it abuts the annular buckle 110, it squeezes the locking block 105 into the groove 103, thereby pulling the return water pilot valve 109 out of the connecting pipe 101, which facilitates the disassembly and installation of the return water pilot valve 109 and the connecting pipe 101.
