Description

Technical Field

[0001] This utility model relates to the field of pressure regulating valves, and in particular to a pressure regulating valve structure. Background Technology

[0002] In existing industrial technology systems and various fluid transmission systems, stable control of pipeline pressure is a key link to ensure the safe and efficient operation of the entire system. In order to avoid excessive pipeline pressure and affect the normal operation of pipeline control valves, it is necessary to install corresponding valve bodies to control pipeline pressure.

[0003] In existing technologies, when the pressure in a single pipeline is too high in various fluid transmission systems, the valves in the system often fail to open properly. To avoid this, the common method used in existing technologies is to equip the pipeline with a pressure reducing valve and a solenoid valve. The pressure reducing valve and the solenoid valve work together to reduce the pressure of the high-pressure fluid. However, in actual use, the pressure reducing valve and the solenoid valve consume a certain amount of energy during operation. With the increase in usage time, the long-term energy consumption will lead to a significant increase in the operating cost of the entire system. Moreover, as precision mechanical devices, the pressure reducing valve and the solenoid valve require regular maintenance and upkeep. The valve core, valve seat and other components inside the pressure reducing valve will wear down during long-term use, resulting in a decrease in pressure reducing effect. The coil, contacts and other components of the solenoid valve are also prone to failure, affecting its normal operation. Therefore, it is necessary to improve the structure of the pressure regulating valve to solve the above problems. Utility Model Content

[0004] To overcome the problem that the energy consumption generated by using pressure reducing valves and solenoid valves to reduce pressure in pipelines increases the overall operating cost of the transmission system.

[0005] The technical solution of this utility model is as follows: a pressure regulating valve structure, including a regulating valve body, a connecting pipe disposed on the regulating valve body, a fastening bolt threaded to the connecting pipe, a diaphragm body disposed between the connecting pipe and the regulating valve body, a first through hole opened on the diaphragm body, a first spring disposed between the diaphragm body and the regulating valve body, an inlet component disposed inside the regulating valve body, and a drain component disposed on the regulating valve body. The water flow pushes the inlet component to move into the regulating valve body, and the drain component controls the water flow to be discharged.

[0006] Preferably, the regulating valve body has a through groove, and the fastening bolt passes through the through groove and is threaded to the connecting pipeline.

[0007] Preferably, the inlet assembly includes an inlet pipe on the regulating valve body, a first sealing ring on the inlet pipe, a pressure gauge body on the regulating valve body, a fixed seat threaded onto the regulating valve body, a first connecting rod on the fixed seat, a fixed plate fixedly connected to the first connecting rod, a valve core body inside the regulating valve body, a second spring between the valve core body and the fixed plate, a second sealing ring on the valve core body, a connecting sleeve fixedly connected to the valve core body, a valve cover on the connecting sleeve, and a third spring between the valve cover and the regulating valve body. Water flows through the inlet pipe into the regulating valve body, where the second sealing ring seals the regulating valve body, the first sealing ring seals the gaps in the inlet pipe, and the second spring provides thrust to the valve core body. When water flows through the inlet pipe, it pushes the valve cover into the regulating valve body, further buffering the water flow and thus reducing pressure.

[0008] Preferably, the inlet pipe has a groove at the relative position of the first sealing ring, and the first sealing ring is disposed inside the groove.

[0009] Preferably, the valve core body has a recess for receiving the second sealing ring at the position opposite to the second sealing ring, and the second sealing ring is disposed inside the recess.

[0010] Preferably, the drainage assembly includes an electromagnet body fixedly connected to the regulating valve body, a magnetic suction plate body, a third sealing ring on the magnetic suction plate body, a fourth spring between the magnetic suction plate body and the electromagnet body, a drainage pipe opened on the regulating valve body, and a fourth sealing ring on the drainage pipe. When the electromagnet body is energized, it generates a suction force, which drives the magnetic suction plate body to move and open the drainage pipe. The fourth sealing ring seals the gaps in the drainage pipe.

[0011] Preferably, the magnetic plate body has a groove for storage at the position opposite to the third sealing ring, and the third sealing ring is set on the groove.

[0012] Preferably, the drain pipe has a groove at the relative position of the fourth sealing ring, and the fourth sealing ring is disposed on the groove.

[0013] The beneficial effects of this utility model are: By cooperating with the diaphragm body and the first spring, the water flow is initially depressurized. Then, the second spring provides thrust to the valve core body to further depressurize the water flow. Compared with the common method of using a pressure reducing valve and a solenoid valve to reduce pressure, there is no need to consume a lot of extra electrical energy to drive complex components such as the solenoid valve, which greatly reduces the overall energy consumption of the conveying system. At the same time, it also reduces the costs incurred in equipment maintenance and replacement, effectively reducing operating costs.

[0014] In terms of response speed, the electromagnet body can instantly generate magnetic force after being energized, enabling the magnetic chuck body and the third sealing ring to move quickly, greatly shortening the adjustment time and improving the system's response efficiency. In terms of control precision, the magnetic force intensity is adjusted by controlling the magnitude of the energizing current of the electromagnet body, thereby controlling the moving distance of the magnetic chuck body and the third sealing ring, thus achieving control of water discharge to meet the strict requirements for water flow control under different working conditions.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 - Figure 5This utility model provides an embodiment of a pressure regulating valve structure, including a regulating valve body 1, a connecting pipe 21 disposed on the regulating valve body 1, a fastening bolt 22 threadedly connected to the connecting pipe 21, a diaphragm body 23 disposed between the connecting pipe 21 and the regulating valve body 1, a first through hole 24 opened on the diaphragm body 23, a first spring 25 disposed between the diaphragm body 23 and the regulating valve body 1, an inlet assembly disposed inside the regulating valve body 1, and a drain assembly disposed on the regulating valve body 1, wherein the water flow drives the inlet assembly. The component moves into the body of the regulating valve 1, and the water flow is controlled by the drainage component to discharge. Before the water flow enters the body of the regulating valve 1 through the connecting pipe 21, the first spring 25 provides a thrust to the diaphragm body 23, and the diaphragm body 23 provides initial buffering for the water flow. The water flow then enters the body of the regulating valve 1 through the first through hole 24. Inside the regulating valve 1, the inlet component further buffers the water flow, thus fully buffering the water flow. After buffering, the drainage component works to make the water flow return to the connecting pipe 21 and then discharge.

[0019] Please see Figure 1 - Figure 4In this embodiment, a through groove is provided on the regulating valve body 1, and a fastening bolt 22 passes through the through groove and is threadedly connected to the connecting pipe 21. By connecting the regulating valve body 1 and its connected components to the connecting pipe 21 with the fastening bolt 22, the pressure of the pipe is reduced. The inlet assembly includes an inlet pipe 27 provided on the regulating valve body 1, a first sealing ring 28 provided on the inlet pipe 27, a pressure gauge body 29 provided on the regulating valve body 1, a fixing seat 210 threadedly connected to the regulating valve body 1, and a fixing seat 210 provided on the fixing seat 29. The following components are present: a first connecting rod 211 on the fixed seat 210; a fixing plate 212 fixedly connected to the first connecting rod 211; a valve core body 213 disposed inside the regulating valve body 1; a second spring 214 disposed between the valve core body 213 and the fixing plate 212; a second sealing ring 215 disposed on the valve core body 213; a connecting sleeve 216 fixedly connected to the valve core body 213; a valve cover 217 disposed on the connecting sleeve 216; a third spring 218 disposed between the valve cover 217 and the regulating valve body 1; and water flows through the inlet pipe 27. The water is delivered to the inside of the regulating valve body 1, where it is sealed by the second sealing ring 215 and the gap in the inlet pipe 27 is sealed by the first sealing ring 28. The second spring 214 provides thrust to the valve core body 213. When water flows through the inlet pipe 27, it pushes the valve cover 217 into the regulating valve body 1, further buffering the water flow and reducing pressure. The inlet pipe 27 has a groove at a position opposite to the first sealing ring 28, and the first sealing ring 28 is located inside the groove. The first sealing ring 28 then provides thrust to the valve core body 213. The flow pipe 27 is protected at the sealing point to prevent water flow from gradually corroding the connection gap of the regulating valve body 1, thereby increasing the overall service life of the regulating valve. The valve core body 213 has a groove for receiving the second sealing ring 215 at the relative position. The second sealing ring 215 is set inside the groove. After the water flow pushes the valve cover 217 and moves the valve core body 213 into the fixed seat 210, the second sealing ring 215 protects the gap, preventing water flow from entering between the valve core body 213 and the valve core body 214, which would corrode the second spring 214 and affect its service life.

[0020] Please see Figure 1 , Figure 5In this embodiment, the drainage assembly includes an electromagnet body 31 fixedly connected to the regulating valve body 1, a magnetic suction plate body 36, a third sealing ring 32 disposed on the magnetic suction plate body 36, a fourth spring 33 disposed between the magnetic suction plate body 36 and the electromagnet body 31, a drainage pipe 34 opened on the regulating valve body 1, and a fourth sealing ring 35 disposed on the drainage pipe 34. When the electromagnet body 31 is energized, it generates a suction force, which drives the magnetic suction plate body 36 to move, opening the drainage pipe 34. The fourth sealing ring 35 seals the gaps in the drainage pipe 34, and the fourth spring 33 provides a thrust to the magnetic suction plate body 36. When water is not needed to be discharged, the magnetic suction plate body 36 and the third sealing ring 32 are closed. 2. To seal the drain pipe 34 and prevent water from flowing out, the magnetic plate body 36 has a groove for receiving the third sealing ring 32 at the opposite position. The third sealing ring 32 is placed in the groove and is received by the groove. When the magnetic plate body 36 is closed, the third sealing ring 32 seals it and prevents water from entering the inside of the electromagnet body 31 and affecting it. The drain pipe 34 has a groove at the opposite position of the fourth sealing ring 35. The fourth sealing ring 35 is placed in the groove and protects the gaps in the drain pipe 34 from the gradual corrosion of the connection gaps of the regulating valve body 1 when water flows out, thereby increasing the overall service life of the regulating valve.

[0021] During operation, before the water flows into the regulating valve body 1 through the connecting pipe 21, the first spring 25 provides a thrust to the diaphragm body 23, which initially buffers the water flow. The water then flows into the regulating valve body 1 through the first through hole 24. Inside the regulating valve body 1, it is guided by the inlet pipe 27. When the water flows through the inlet pipe 27, the first sealing ring 28 protects the gaps in the regulating valve body 1, preventing water from flowing out from the connecting gaps. After passing through the inlet pipe 27, the water pushes the third spring 218, causing the valve cover 217 and the valve core body 213 to move downwards. After the valve core body 213 is housed inside the fixed seat 210, it is further protected by the second sealing ring 215. To prevent water from entering the inner side of the fixed seat 210, the water flow provides a thrust to the valve core body 213 and other components through the second spring 214, thereby further buffering the water flow. The water flow that enters the inside of the regulating valve body 1 is detected and displayed by the pressure gauge body 29. When discharged, the electromagnet body 31 is powered to generate an attraction force, which drives the magnetic suction plate body 36 to move outward, thereby opening the drain pipe 34. After the drain pipe 34 is opened, the water flow is guided through the drain pipe 34. When passing through the drain pipe 34, the fourth sealing ring 35 protects the connection gap of the regulating valve body 1, and the water flows back into the inside of the connecting pipe 21 before being discharged.

[0022] Through the above steps, the water flow is initially reduced by the cooperation between the diaphragm body 23 and the first spring 25. Then, the second spring 214 provides thrust to the valve core body 213 to further reduce the water flow. This solves the problem that the energy consumption generated by the pressure reducing valve and the solenoid valve working together to reduce the pressure in the pipeline will increase the overall operating cost of the transmission system.
