Problems solved by technology

The first connection method requires conversion joints, high cost, many connections, and cumbersome assembly. In addition, the more connection conversions, the more prone to water leakage.
If the second connection method is used, the welding ring needs to be ultrasonically welded on the solenoid valve body when fixing the 1 / 4 buckle. Since ultrasonic welding is affected by many factors such as air pressure, time, temperature, and vibration frequency, it is prone to uneven welding , instability and other problems; under high water pressure, water seepage will occur, or even fall off and fail; in addition, ultrasonic welding may produce overflow residue, once it falls into the cavity of the solenoid valve, it will cause the entire solenoid valve to leak; finally , Ultrasonic welding is not easy to inspect, reliability cannot be verified

Embodiment

[0020] Such as figure 1 As shown, a solenoid valve with fast plug-in buckle connection includes a valve body 4 and a buckle 1, the valve body 4 is an axisymmetric structure, and the buckle 1 is connected to both ends of the valve body 4, so The valve body 4 described above is connected to the PE pipe through a buckle 1. The valve body 4 is provided with a diaphragm 6, a moving iron core 8, a spring 9, a coil part 11 and a valve cover 10, and one end of the moving iron core 8 is provided with a seal 7 , The diaphragm 6 is set on the diaphragm support 5 . The solenoid valve also includes an O-ring 3 and a compression cover 2, the compression cover 2 is arranged on the buckle 1, and is snap-connected with the valve body 4, and the O-ring 3 is arranged on the buckle 1 and valve body 4. The solenoid valve uses the elasticity of the compression cover 3 to permanently press the compression cover into the valve body 4, fix the buckle 1, use the buckle 1 to grasp the PE pipe, and use...

Abstract

The invention relates to a fast plug-type buckle connected solenoid valve. The fast plug-type buckle connected solenoid valve comprises a valve body and a buckle; the valve body is of an axisymmetric structure; the buckle is connected at two ends of the valve body; the valve body is connected with a PE (polyethylene) pipe through the buckle. The fast plug-type buckle connected solenoid valve also comprises an O ring and a clamping cap; the clamping cap is arranged on the buckle and is connected with the valve body in a buckle manner; the O ring is arranged between the buckle and the valve body. Compared with the prior art, the fast plug-type buckle connected solenoid valve has the advantages of low cost, high reliability, high assembly efficiency and the like.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a solenoid valve with quick-insert buckle connection. Background technique [0002] At present, the connection between the solenoid valve and the pipeline PE pipe on the market: one is through a conversion joint; the other is a snap-on solenoid valve using ultrasonic welding. The first connection method requires conversion joints, which is costly, has many connections, and cumbersome assembly. In addition, the more connection conversions, the more prone to water leakage. If the second connection method is used, the welding ring needs to be ultrasonically welded on the solenoid valve body when fixing the 1 / 4 buckle. Since ultrasonic welding is affected by many factors such as air pressure, time, temperature, and vibration frequency, it is prone to uneven welding , instability and other problems; under high water pressure, water seepage will occur, or even fall off and fail; in addition, ultras...
