Gate valve structure with emergency open function and implementation method

Abstract

The invention belongs to the technical field of valves and relates to the improving process and technology of gate valves, in particular to a gate valve structure with an emergency open function and an implementation method. The problem of pipeline blockage caused by falling of a gate plate of a gate valve can be solved through the gate valve structure and the implementation method under the circumstance that the gate valve for a pipeline does not need to be replaced, and normal circulation of media in the pipeline is guaranteed. Compared with the prior art, the gate valve structure and the implementation method have the advantages that the problem of pipeline blockage caused by falling of the gate plate of the gate valve can be solved under the circumstance that the gate valve for the pipeline does not need to be replaced, normal circulation of the media in the pipeline is guaranteed, the gate valve is not limited to heating pipelines any longer, and general promotional value of other gate valves for pipelines with media is achieved; the problem that during heating in the north, once the gate plate of the gate valve falls off, the gate valve for the pipeline needs replacing and heating must be stopped is solved, influences on heating for residents and enterprise and public institutions are reduced, labor intensity of workers is relieved, the replacement cost of the gate valve is saved, and work efficiency is improved; the structure is simple, implementation is easy, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to an improved process and technology of a gate valve, in particular to a structure and a realization method of a gate valve with an emergency opening function. Background technique [0002] Gate valves are widely used in pipeline connections in industrial and agricultural production and people's daily life, and are one of the common parts for pipeline connections to transport fluid media. Due to the influence of the conveying medium such as water and the accumulation of time, it is easy to cause the gate valve to rust and fail, and it is not easy to open or close. Under long-term immersion and corrosion, the gate valve in the heating pipeline is often corroded. In severe cases, the valve plate of the gate valve will fall off, causing the valve to fail to open or close. The phenomenon of large-scale freezing and stopping of heating occurs from time to time, which brings great inconven...
