Technical Field
The utility model relates to a low-leakage high-sealing valve, in particular to a fire-fighting low-leakage high-sealing valve.
Background
In gaseous fire extinguishing system, fire extinguishing agent bottle group and drive gas bottle group all probably have gas leakage, because the pipe network is connected, when the gas of leakage gets into starting pipeline or pressure manifold and reaches certain pressure, can lead to fire extinguishing system malfunction, the low high valve that seals that leaks is installed on starting pipeline or pressure manifold, can realize releasing the low pressure gas of the internal leakage of starting pipeline or pressure manifold of fire extinguishing system, the pipe network steps up when the system normally sprays, the low high valve that seals that leaks can in time close, do not influence the system and normally put out a fire.
The existing low-leakage high-sealing valves are mostly in simple ball-type one-way valve structures or piston sealing ring structures, the installation has requirements on the position, and the direction change can influence the opening and closing pressure; the reliability of multiple actions is poor, and in addition, part of low-leakage high-sealing valves adopt piston sealing rings and spring structures, are similar to one-way valves, and have the advantages of complex structure, large overall dimension, high cost and inconvenience in installation.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a fire-fighting low-leakage high-sealing valve, which is used for solving the problems of the existing fire-fighting low-leakage high-sealing valve in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a fire control is low lets out high valve that seals, includes the valve body, one side fixed mounting of valve body has the screw thread end, the inside fixed mounting of screw thread end has the retaining ring, the inside of valve body is close to one side position fixed mounting and has the case, be provided with first sealing washer between case and the valve body, one side fixed mounting of valve body has the second sealing washer, the inside fixed mounting of valve body has the spring.
As a further scheme of the utility model: the valve body is in a hexagonal transition with a cylindrical surface.
As a still further scheme of the utility model: the outer surface of the valve core is an inclined surface and is installed in a matching mode with the first sealing ring.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 4, in the embodiment of the utility model, a fire-fighting low-leakage high-sealing valve comprises a valve body 1, a threaded end 2 is fixedly installed on one side of the valve body 1, a retainer ring 3 is fixedly installed inside the threaded end 2, a valve core 4 is fixedly installed in the position, close to one side, inside the valve body 1, a first sealing ring 5 is arranged between the valve core 4 and the valve body 1, a second sealing ring 6 is fixedly installed on one side of the valve body 1, and a spring 7 is fixedly installed inside the valve body 1.
Specifically, the valve body 1 is in the shape of hexagonal belt cylindrical surface transition.
In this embodiment, the hexagonal size is compact, prevents that installation moment is too big, and the face of cylinder makes things convenient for sign product name.
Specifically, the outer surface of the valve core 4 is an inclined surface and is installed in a matching manner with the first sealing ring 5.
In the embodiment, the valve core 4 is matched with the first sealing ring 5 by adopting an inclined plane, so that the sealing is reliable and the process is simple.
