Description

Technical Field

[0001] The invention relates to a valve, in particular to a push-pull switching valve. Background Art

[0002] There are two main valve core structures used in existing angle valves, one is a ceramic valve core structure and the other is a ball core structure. However, these two valve cores have their own advantages and disadvantages. The structure adopted by the ceramic valve core is that two ceramic plates fit each other and control the water flow area by the relative rotation angle. Its advantage is small switching force, and its disadvantages are small flow, many parts, complex structure, and cumbersome installation. The structure adopted by the ball core is a ball core and two sealing pieces. Its advantage is large flow, and its disadvantage is that in order to ensure the sealing degree, the ball core and the sealing pieces are installed very tightly, resulting in large switching force and effort.

[0003] Most of the existing angle valves are switched by rotation, that is, a handle is designed for the angle valve, and the water channel is opened and closed by rotating the handle. The control method is single and there are more control components, which increases the cost. In addition, users cannot figure out which is left-handed and which is right-handed to open the water channel and which is right-handed to close the water channel, and the control instructions are vague.

[0004] The water outlet of the existing angle valve is fixed to the body, but the direction in which the angle valve is installed in the water pipe is uncertain, which will cause the direction of the final water outlet to be not the desired angle, and then cause the hose connected thereto to be entangled.
