Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1-5, in the embodiment of the utility model, a water valve with a pneumatic control system comprises a water valve shell 1, a water valve needle valve 3 is installed in the water valve shell 1, and the connection part of the tip of the water valve needle valve 3 and the water valve shell 1 is in sealing connection through a first teflon gasket 8; an elastic gasket 11 is arranged in the middle annular groove of the water valve needle valve 3, a second star-shaped ring 10 is arranged on the outer side of the elastic gasket 11, and a first star-shaped ring 9 is arranged in the tail annular groove of the water valve needle valve 3; the tail end threaded connection of water valve casing 1 has water valve nut 4, sealing connection is carried out through first O type sealing washer 2 in the junction outer end between water valve nut 4 and the water valve casing 1, the one end threaded connection of water valve nut 4 has trachea elbow 6.
