Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a mounting structure for solenoid valves. Background Art

[0002] A solenoid valve is a valve controlled by an electromagnetic force. It is a component used to control the flow of fluids and is used in industrial control systems to adjust the direction, flow rate and other parameters of the medium. The most commonly used ones are check valves, safety valves, directional control valves, etc.

[0003] As shown in the application number 202222566136.1, the utility model discloses a connection structure for installing a solenoid valve, including a valve sleeve, both ends of the valve sleeve are fixedly connected with connecting pipes, the inner wall of the connecting pipe is fixedly connected with a heating ring at one end close to the valve sleeve, and the two ends of the valve sleeve are movably connected with sealing plugs relative to the connecting pipe, and the sealing plugs are plugged into the connecting pipe. The utility model has the following advantages: when the solenoid valve is connected to a PVC pipe, the sealing plugs are first controlled to be inserted into the connecting pipes at both ends. After the pipe is inserted, the heating ring heats the pipe and melts it, so that the pipe is hot-melted and filled into the slot, so that the pipe cooperates with the slot on the inner wall of the heating ring. After the heating ring is turned off and cooled, there is no gap between the outer wall of the pipe and the valve, which increases the sealing effect and is extremely convenient for installation and disassembly. However, the heating ring of the installation structure of the solenoid valve is integrated with the installation structure, so the device is large in size, which makes it inconvenient to heat the PVC pipe and connect the installation structure to it after heating. In addition, a water hammer effect will occur when the solenoid valve is working. The device does not have the function of eliminating the water hammer effect, which makes it inconvenient to extend the service life of the water pipe and is inconvenient for workers to operate during connection.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and an installation structure for a solenoid valve is proposed. Utility Model Content
