Novel quick-opening type valve

Abstract

The invention discloses a novel quick-opening type valve which comprises a valve main body and a handle. One side of the upper end of the valve main body is connected with the handle through a handlesleeve base. A base with holes is installed at the bottom of the valve main body. The surface of the valve main body is symmetrically provided with an air inlet port and an air outlet port which are located on the upper side of the base with the holes. The air inlet port communicates with the air outlet port through a valve element cavity. A valve element body is arranged inside the valve elementcavity. The valve element body is of an O-shaped ring structure. The valve element body is connected with a guide rod through a fixed base. The upper end of the guide rod is connected with a guide shaft through a spring. The guide shaft is connected with an eccentric wheel through a guide shaft circular groove formed in the side surface of a handle base, the eccentric wheel is connected with a square rod through an eccentric shaft, the eccentric shaft is installed inside a bearing housing, the square rod penetrates through a reset groove to be connected with a handle core base of the handle, the handle is of a line-styled structure, ring bases are symmetrically installed on the surface of the upper outer side of the handle, and cleanliness is high.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a novel quick-opening valve. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the shortcomings of the existing technical solutions, the present invention provides a new type of quick-opening valve, which not only solves the wear problem caused by the use of Corker-type packing ball valves, but also greatly increases the usability of the valve and improves the The efficiency of work is convenient for people to operate in construction, and it has the function of increasing force, and it is convenient for users to operate and use, which can effectively solve the problems raised by the background technology
