Self-control large-diameter quick-cut corrugated pipe gate valve

Abstract

The invention relates to the technical field of gate valves, in particular to a self-control large-diameter rapid cutting corrugated pipe gate valve. According to the technical scheme, the gate valve comprises a mounting plate, a gate valve body and a second rotating disc, a sliding block is slidably mounted at the top of the mounting plate, a supporting frame is movably mounted at the top of the sliding block, the gate valve body is fixed to the top of the mounting plate in a limiting mode, and a water inlet and a water outlet are fixedly formed in the two sides of the gate valve body respectively; a clamping sleeve matched with the water inlet and the water outlet is movably installed on the top of the supporting frame, and a valve deck is fixedly installed on the top of the gate valve body. Through mutual cooperation of a sliding block, a first movable rod, a clamping sleeve and a supporting frame, a water inlet and a water outlet can be fixed through the clamping sleeve, so that buffering operation can be effectively performed in the closing and opening process of the gate valve main body, the impact force is prevented from being too large, and the service life of the gate valve main body is prolonged. And the gate valve main body is damaged by shaking.

Description

technical field [0001] The invention relates to the technical field of gate valves, in particular to an automatic control large-diameter quick-cut bellows gate valve. Background technique [0002] The gate valve is an opening and closing gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed through the contact between the valve seat and the gate, usually sealed. The surface will be surfacing metal material to increase wear resistance. The gate has rigid gate and elastic gate. According to the difference of gate, gate valve is divided into rigid gate valve and elastic gate valve. The opening and closing part of gate valve is gate, and the movement of gate The direction is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has t...

Problems solved by technology

[0005] 1. The existing self-controlled large-diameter quick cut-off bellows gate valve does not have a good buffer structure. When the current gate valve is in use, due to the large water flow inside the bellows, in the process of closing and opening the gate, through the water flow The impact force will cause the gate valve to shake, which is inconvenient to buffer and easy to cause damage to the gate valve;

[0006] 2. The general self-controlled large-caliber quick-cut bellows gate valve is inconvenient to install and operate. When docking with the bellows, due to the different positions of the bellows and the gate valve, it is necessary to manually lift the gate valve to align with the bellows, and the installation operation is time-consuming and laborious. , which reduces the convenience, so we propose a self-controlled large-diameter quick cut-off bellows gate valve to solve the existing problems
