Gate valve convenient to dismount and mount

Abstract

The invention discloses a gate valve convenient to dismount and mount. The gate valve comprises a gate valve pipeline. A closing device cooperating with the gate valve pipeline is arranged at the upper end of the gate valve pipeline, the two ends of the gate valve pipeline are connected with connecting pipelines, the side walls of the sides, close to the gate valve pipeline, of the connecting pipelines are fixedly connected with annular lugs, annular grooves matched with the annular lugs are formed in the side wall of the gate valve pipeline, two sliding grooves with opposite opening directions are symmetrically formed in the annular lugs, the inner walls of the sides, close to each other, of the two sliding grooves are connected with clamping blocks through first springs, clamping groovesmatched with the clamping blocks are formed in the inner walls of the annular grooves, abutting rods are slidingly connected into the clamping grooves, and the ends, away from the clamping blocks, ofthe abutting rods penetrate through the gate valve pipeline. The gate valve is easy to operate and convenient to use, connection or disconnection between the gate valve pipeline and the connecting pipelines is easy and rapid, a large amount of time is saved while the labor intensity of workers is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gate valves, in particular to a gate valve which is easy to disassemble and install. Background technique [0002] The valve is a control component in the fluid conveying system, which has functions such as cut-off, regulation, flow diversion, reverse flow prevention, voltage stabilization, flow diversion or overflow pressure relief. The gate valve is one of the valves. The direction of movement of the plate is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its manufacturability and compensate for the deviation of the sealing surface angle during processing. The plate is called the elastic gate. [0003] When some gate valves are connected t...

Problems solved by technology

[0003] When some gate valves are connected to the connecting pipeline, the gate valve and the connecting pipeline are fixedly connected by twisting the bolts. The operation is more troublesome, especially when the bolts are continuously twisted, the labor intensity of the staff is very high, and it takes a long time. Reduced work efficiency; for this reason, we propose a gate valve that is easy to disassemble and install to solve these problems
