Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0021] Such as figure 1 , figure 2 As shown, the present invention includes a valve body 1, a flow channel arranged in the valve body 1 and a valve cover 2 arranged on the valve body 1, the valve body 1 and the valve cover 2 at the upper end of the valve body 1 close to the water inlet There is a groove between the valve body 1 and the valve cover 2. The groove between the valve body 1 and the valve cover 2 is composed of the first groove on the upper end surface of the valve body 1 and the second groove on the lower end surface of the valve cover 2. Together, the groove is provided with a support shaft 3.1, and the support shaft 3.1 is fixedly connected with a flexible rubber flap 3 for sealing the valve body 1; there are two c...

Abstract

The invention relates to a rotary intercept rubber-flap check valve and belongs to the technical field of control devices on medium pipelines. The rotary intercept rubber-flap check valve comprises a valve body, a flowing channel arranged in the valve body and a valve cover arranged on the valve body, a groove is arranged between one end close to a water inlet of the valve body and the valve cover, a supporting shaft is arranged in the groove, and a flexible rubber flap for sealing the valve body is fixedly connected onto the supporting shaft. Two sides of the valve body are provided with two coaxial installing holes, rotary shafts are arranged in the installing holes, one end of a limiting rod is connected onto the corresponding rotary shaft, the other end of the limiting rod abut against the flexible rubber flap, and rotary shafts are electrically connected with an electric driving device. The rotary intercept rubber-flap check valve has an intercepting (adjusting) function, the electric driving device is installed on one side of the valve body and drives the rotary shafts to rotate, the rotary shafts drive the limiting rods to rotate, and accordingly opening-angle adjustment of the valve is achieved.

Description

technical field [0001] The invention belongs to the technical field of control equipment on medium pipelines, and in particular relates to a rotary type shut-off rubber disc check valve. Background technique [0002] In the existing check valve, the valve disc is a rigid structure of metal material. Due to the reason of the metal material, its own gravity is relatively large. In the water system with low pressure (or no pressure), the valve disc of the check valve cannot be The water flushes away, and then plays the role of check, and in the existing check valve, the free adjustment of the opening of the disc cannot be realized, so as to control the size of the water flow, so according to the lower pressure (or no pressure) Designing a non-return device for the water supply system has become a technical problem. Contents of the invention [0003] The object of the present invention is to provide a rotary shut-off rubber disc check valve aiming at the defects of the prior ...
