Embodiment Construction

[0017] Such as figure 1 As shown, the four-sided valve of the present invention includes a valve body 100 , an inner ring 200 , an upper rubber tympanic membrane 300 , a lower rubber tympanic membrane 400 , and a piston 500 .

[0018] The valve body 100 is composed of an upper cover 101 and a lower cover 102, and the valve body 100 formed by combining the upper cover 101 and the lower cover 102 has a valve chamber 103, and the upper cover 101 has a separated water inlet channel 104 and a water outlet channel. 105 , the water inlet passage 104 and the water outlet passage 105 have two through holes 106 , 107 communicating with the valve chamber 103 at positions close to the center of the valve chamber 103 . The lower cover 102 has a pressure applying channel 108 inside, and above the pressure applying channel 108 there is a water chamber 109 communicating with the pressure applying channel 108 and also communicating with the valve cavity 103 .

[0019] The inner ring 200 , the...

Abstract

The invention relates to a four-sided valve. In the technical scheme, a valve chamber, a water inlet channel, a water outlet channel and a pressure channel are arranged in a valve body, wherein the water inlet channel, the water outlet channel and the pressure channel are communicated with the valve chamber, an upper rubber tympanic membrane, a lower rubber tympanic membrane and a piston arranged between the upper rubber tympanic membrane and the lower rubber tympanic membrane are arranged in the valve chamber, the lower rubber tympanic membrane is used for blocking the pressure channel and the valve chamber, the piston can move up and down under the action of water pressure in the pressure channel so as to selectively block the upper rubber tympanic membrane or communicate the water inlet channel and the water outlet channel and is formed by connecting an upper part and a lower part, the upper part of the piston is made of elastic material, and the lower part of the piston is made of hard material. The four-sided valve has the advantages of long service life, rapid cutting-off of water and good sealing performance.

Description

technical field [0001] The invention relates to a valve, in particular to a four-sided valve specially applied to a water purifier. Background technique [0002] The four-way valve is a special valve that controls the on-off of the other waterway through the water pressure of one waterway. Due to this characteristic, it is now widely used in water purifiers. It can control the water purification according to the water pressure of the pure water outlet of the water purifier. The on-off of the waterway at the raw water inlet end of the device. [0003] At present, it is found in the actual use of the existing four-sided valve that the rubber tympanic membrane in the valve is easily damaged, resulting in water leakage from the valve, and the service life of the four-sided valve is relatively short. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a four-sided valve with no damage to the rubber tympanic membrane. The...
