Novel low-flow-gas push button valve

Abstract

The invention provides a novel low-flow-gas push button valve which comprises a valve body, wherein a deep cavity is formed in the valve body; the end part of the deep cavity is in threaded connectionwith a valve cap; the valve body is perpendicular to the deep cavity, and a first cavity and a second cavity are respectively formed in two symmetric sides; a position, which is close to the bottom,of the first cavity is connected with a conical cavity; a gas outlet hole communicating with the deep cavity is formed in the conical cavity; the bottom of the second cavity is provided with a gas inlet hole communicating with the deep cavity; a baffle plate is arranged at one end, which is close to an inner cavity of the valve cap, of a valve rod; a sealing ring is also arranged at one end, whichis far away from the valve cap, of the valve rod; two ends of the sealing ring are connected respectively through a first gas barrier plate and a second gas barrier plate; a conical sliding block isarranged on the second gas barrier plate; and a spring is arranged between the bottom of the deep cavity and the conical sliding block. By simple structural matching, quick opening and closing of thenovel low-flow-gas push button valve provided by the invention are realized, and the flow is relatively low; and the whole valve is relatively high in stability, has a self-breakage function and is higher in safety, and the life of the novel low-flow-gas push button valve is prolonged.

Description

technical field [0001] The invention belongs to the field of valves, in particular to a novel small-flow gas button valve. Background technique [0002] There are some components for detecting gas pressure and flow in industrial combustion pipeline equipment. The gas flow required by these components is small. Using butterfly valves, ball valves and other large-range control valves will often damage components. In order to ensure better detection results, To prevent accidents, a special small flow valve that can be closed quickly at any time is required to ensure the safety of the equipment. In view of this situation, the present invention proposes a new type of small-flow gas button valve, which realizes the rapid opening and closing of the valve through simple structural cooperation, the flow rate is small, the stability of the entire valve is strong, and it has a self-cutting function to ensure It ensures the safety of the terminal device, prolongs its life, and ensures ...
