Problems solved by technology

[0003] The sealing performance of traditional water valves is no leakage under the water pressure of 0.02~0.8MPa. This kind of water valve cannot achieve the sealing effect under lower water pressure. In practical applications, the working water pressure is often lower than 0.02MPa. , which caused a slight leakage of the water valve, which affected the actual use effect of the product; in addition, the traditional connection structure of the water valve inlet and outlet is a welding structure, the welding assembly process is complicated and difficult, the assembly cost is high, and the welding process is easy. Generate welding waste, affect the performance of the connection structure of the water inlet and outlet, and even cause problems such as water leakage

Abstract

The invention relates to a solenoid valve, in particular to a high-sealability fast connection water valve which comprises a valve body, a sealing ring, a sealing ring frame, a booster spring, a coilguide rod component and fast connection mechanisms, wherein the sealing ring is nested on the sealing ring frame. A central boss of the sealing ring frame is matched with the valve body, a spring positioning boss is arranged on the bottom surface of the top of the sealing ring frame and matched with the top end of the booster spring, the bottom end of the booster spring is matched with a spring base of the coil guide rod component, the booster spring jacks the sealing ring frame, the fast connection mechanisms are arranged at a water inlet and a water outlet on two sides of the valve body, a connecting terminal and the valve body are structurally integrated, and a sealing O-shaped ring is arranged in the connecting terminal and connected together with the connecting terminal in a fastenedmanner through a fastening structure and a fast connection cap. According to the high-sealability fast connection water valve, the valve body is excellent in sealing performance at ultra-low water pressure, leakage is avoided, the fast connection mechanisms at the water inlet and the water outlet are of fastening structures, convenient to assemble and good in sealability.

Description

technical field [0001] The invention relates to an electromagnetic valve, in particular to a fast-connecting water valve with high sealing performance, which belongs to the technical field of electromagnetic control valves. Background technique [0002] With the promotion of smart homes, the water appliance industry has developed rapidly, and various water valves applied to smart home water equipment have developed rapidly. The water valves used in the existing water home appliance industry mainly use pilot solenoid valves, pilot solenoid valves, and At this time, the valve stem is lifted by the electromagnetic force, and the pilot valve port is opened. At this time, the upper cavity of the solenoid valve is relieved through the pilot hole, and a pressure difference is formed around the main valve core. Under the action of the pressure difference, the fluid pressure pushes the main valve. The spool moves upward to open the main valve port; when the power is off, under the ac...
