Abstract

The invention discloses a valve. The valve comprises a valve shell body, an upper valve clack, a lower valve clack, a first elastic part and a second elastic part, wherein the valve shell body is internally provided with a hole passage, the upper valve clack comprises a downward spherical surface, the lower valve clack comprises a spherical groove adapted to the spherical surface, the spherical surface directly faces the spherical groove, the first elastic part is connected between the upper valve clack and the hole passage in a sealed manner, and the second elastic part is connected between the lower valve clack and the hole passage in a sealed manner. The valve can be controlled according to the flow quantity.

Description

technical field [0001] The invention relates to the fields of construction pipelines, valves and the like, in particular to a valve. Background technique [0002] The basic structure of the valve is composed of valve disc, valve disc, valve cover and handle. The valve disc is installed in the cavity of the valve disc. Install the handle on one end of the disc, and use the rotation angle of the control handle to move within the range of 0 to 90 degrees to realize the opening and closing of the valve. This structure in the prior art usually realizes the opening and closing of the valve clack manually, and the valve clack cannot be opened or closed according to actual needs, and the valve cannot be controlled by the flow rate of the fluid flowing through the valve. Contents of the invention [0003] The object of the present invention is to provide a valve to solve at least one technical problem in the prior art. [0004] The technical solution to achieve the above purpose ...
