Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, specifically to a electromagnetic valve pressure regulating structure. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices used as basic components for fluid control in automation systems. They are generally used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. By adjusting the solenoid valve, different circuits can be used to achieve the desired control. Pressure regulating solenoid valves are a type of solenoid valve.

[0003] Application number "CN202322451210.X" discloses a solenoid valve with a pressure-blocking adjustment structure, comprising: a hollow housing with a connecting pipe on one side inside the housing, and transmission plates equidistantly arranged inside the connecting pipe; memory metal springs symmetrically arranged on one side of the transmission plates, with one end of the memory metal springs abutting against the surface of a silicone gasket; and a telescopic rod, which is annularly and equidistantly installed inside the connecting pipe, the telescopic rod communicating with the inside of the silicone gasket through an L-shaped pipe, and the output end of the telescopic rod contacting the outer wall of the contraction tube. This solenoid valve with a pressure-blocking adjustment structure further depressurizes the liquid to the outside by connecting a ramp pipe inside the locking tube and engaging a drain pipe with an internal groove in the locking tube. It also allows the fluid inside the housing to be discharged to the outside through the locking tube, preventing overload of the internal pressure of the solenoid valve, which could damage the internal seals and cause leakage, thus regulating the internal pressure.

[0004] The aforementioned solenoid valves perform frequent start-up and shut-down actions during operation. Each start-up generates a significant impact force, which puts considerable tension on the connection between the connecting pipe and the pipeline. Over time, this can damage the hydraulic pipe connection or the solenoid valve joint, leading to hydraulic oil leakage. Furthermore, due to the lack of sealing components, the connection between the pipeline and the connecting pipe is not very secure, making leakage a likely possibility. Summary of the Invention

[0005] To address the issues raised by the aforementioned solenoid valves, which frequently start and stop during operation, generating significant impact force with each start-up and resulting in substantial tensile stress at the connection between the connecting pipe and the pipeline, potentially damaging the hydraulic pipe connection or solenoid valve joint after prolonged use and causing hydraulic oil leakage, and furthermore, the lack of sealing components after the pipeline and connecting pipe are connected leads to poor sealing and potential leakage, this invention aims to provide a solenoid valve pressure regulating structure.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a solenoid valve pressure regulating structure, including a solenoid valve body, a connecting pipe connected to the outer surface of the solenoid valve body, a sealing assembly connected to the connecting pipe, and an auxiliary stabilizing connection assembly connected to the solenoid valve body.

[0007] The auxiliary stabilizing connection assembly includes a first arc-shaped plate and a second arc-shaped plate. Two limiting holes are provided on the outer surface of the connecting pipe, symmetrically arranged on the outer surface of the connecting pipe. A first limiting block is fixedly provided on the inner surface of the first and second arc-shaped plates, and the first limiting block is movably inserted into the limiting hole. A connecting plate is fixedly provided on one side of both the first and second arc-shaped plates, and an arc-shaped positioning plate is fixedly provided at the other end of the connecting plate. A movable rod is fixedly provided on the arc-shaped limiting block, and the movable rod movably passes through the arc-shaped positioning plate. A screw is threadedly inserted into the arc-shaped positioning plate, and an arc-shaped limiting block is rotatably provided at the end of the screw. A rubber block is fixedly provided on the inner surface of the arc-shaped limiting block, and several rubber blocks are arranged in a circular array on the inner surface of the arc-shaped limiting block. Through holes are provided on both the first and second arc-shaped plates, and a second bolt is movably inserted into the through hole. A nut is threaded onto the outer surface of the second bolt.

[0008] Preferably, the sealing assembly includes an annular groove formed on one side of the connecting pipe. An annular airbag is fixedly disposed inside the annular groove. An air inlet pipe is provided on the outer surface of the annular airbag and passes through the connecting pipe. A screw cap is threadedly connected to the outer surface of the air inlet pipe. An external thread is provided on the outer surface of the air inlet pipe, and an internal thread is provided on the inner surface of the screw cap. The external thread and the internal thread cooperate with each other. A protective shell is connected to the outer surface of the connecting pipe. The air inlet pipe is disposed inside the connecting pipe. A baffle is rotatably disposed on the protective shell. A first bolt is threadedly inserted into the baffle, and the end of the first bolt is threadedly inserted into the protective shell.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model involves inserting the first limiting block set inside the first arc plate and the second arc plate into the limiting hole, then inserting the second bolt into the through hole, and then putting the nut on the second bolt. After that, the screw can be rotated to drive the arc limiting block to move towards the outer wall of the pipe. The rubber block contacts the outer wall of the pipe, thereby increasing the friction and improving the stability of the connection between the connecting pipe and the pipe.

[0011] 2. After connecting the external pipe to the connecting pipe, the cap can be rotated to detach it from the air inlet pipe. Then, air can be pumped into the air inlet pipe using an air pump to make the annular airbag rotate. The expanded annular airbag can block the gap after the pipe and the connecting pipe are connected, thereby improving the sealing performance. Attached Figure Description

An arc-shaped positioning plate 36 is fixedly provided at the other end of the connecting plate 35. A screw 37 is threaded onto the arc-shaped positioning plate 36. An arc-shaped limiting block 38 is rotatably provided at the end of the screw 37. A rubber block 381 is fixedly provided on the inner surface of the arc-shaped limiting block 38.

A nut 41 is threaded onto the outer surface of the second bolt 42. By inserting the first limiting block 34 provided in the first arc plate 32 and the second arc plate 33 into the limiting hole 31, the second bolt 42 can be inserted into the through hole 4 on the first arc plate 32 and the second arc plate 33. After the nut 41 is fitted onto the second bolt 42, the screw 37 can be rotated to drive the arc limiting block 38 to move towards the outer wall of the pipe. The rubber block 381 contacts the outer wall of the pipe, thereby increasing the friction and improving the stability of the connection between the connecting pipe 11 and the pipe.

[0022] A movable rod 39 is fixedly provided on the arc-shaped limiting block 38. The movable rod 39 movably passes through the arc-shaped positioning plate 36 to assist the arc-shaped limiting block 38 in moving up and down. Several rubber blocks 381 are provided, and the rubber blocks 381 are distributed in a ring array on the inner surface of the arc-shaped limiting block 38, which can improve the stability after connection and increase friction.

Then, air can be pumped into the air inlet pipe 23 using an air pump to rotate the annular airbag 22.

Then, the baffle 26 can be rotated to cover the swivel cap 24 and the air inlet pipe 23.

[0025] The first limiting block 34, which is provided in the first arc plate 32 and the second arc plate 33, can be inserted into the limiting hole 31. Then, the second bolt 42 can be inserted into the through hole 4 opened on the first arc plate 32 and the second arc plate 33. After the nut 41 is put on the second bolt 42, the screw 37 can be rotated to drive the arc limiting block 38 to move towards the outer wall of the pipe.
