Blind plate valve with quick sealing function

Abstract

The invention is applicable to the technical field of blind plate valves, and provides a blind plate valve with a quick sealing function. The blind plate valve comprises a blind plate, two valve bodies and a sealing mechanism, wherein the blind plate is provided with a through hole; the two valve bodies are oppositely arranged on the two sides of the blind plate, and each valve body is provided with a flow channel; the blind plate can move relative to the valve bodies, and when the two valve bodies coincide with the through hole of the blind plate in position, the two flow channels communicate; and the sealing mechanism comprises a sealing execution assembly and a sealing driving assembly, the sealing execution assembly comprises a sealing cylinder, the sealing cylinder is slidably arranged on one valve body and can move in the axis direction of the corresponding valve body under the driving of the sealing driving assembly, and the sealing cylinder is used for sealing a gap between the corresponding valve body and the blind plate. The blind plate valve is quick in switching, can conveniently turn a pipeline off or on, and has the advantages of being good in sealing effect, convenient to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of blind plate valves, and in particular relates to a fast-sealing blind plate valve. Background technique [0002] In many industries, such as construction, gas, and municipal industries, there is a need to cut off the pipeline, especially in the case of valve leakage, etc., it is necessary to quickly shut off the pipeline. [0003] The existing common method for pipeline closure is to use an "8"-shaped blind plate, and its installation generally includes the following steps: 1. Loosen the bolt; 2. Rotate the figure-eight blind plate; 3. Install the winding pad; The winding pad is centered; 5. The bolts are pre-tightened symmetrically, and finally tightened by a full circle. [0004] However, the main problems in the operation switching are: difficult operation, complicated operation process, when the blind plate is large in size, hoisting equipment is required, and it takes a day or even longer to switch ...

AI Technical Summary
