Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0021] refer to Figure 1-5 As shown, a constant pressure container valve includes a valve body 1, a valve stem 2 movable in the valve body 1, and a position limiting mechanism. The valve body 1 includes an upper cavity a, a middle cavity b and a lower cavity c. The connection between the middle part of the valve stem 2 and the upper cavity a an...

Abstract

The invention discloses a constant-pressure container valve. The valve comprises a valve body, a valve rod and a limiting mechanism, wherein the valve rod is connected inside the valve body in a sealed manner; a gas inlet and a gas outlet are formed in the valve body; a pressure adjusting mechanism and a gas exhaust channel matched with the pressure adjusting mechanism are arranged on the valve body; the gas exhaust channel can communicate with the gas inlet, the inside of the valve body and the outside; the gas exhaust channel can be matched with the valve rod and the limiting mechanism, so that the pressure adjusting mechanism has a first working position and a second working position; when the pressure adjusting mechanism is located in the first working position, part of high-pressure gas in the gas exhaust channel can push the pressure adjusting mechanism to move upwards, the gas exhaust channel communicates with the outside, and part of the high-pressure gas in the gas exhaust channel pushes the valve rod to move downwards to open the container valve; when the pressure adjusting mechanism is located in the second working position, the gas exhaust channel is isolated from the outside by the pressure adjusting mechanism, the high-pressure gas in the gas exhaust channel pushes the valve rod to move downwards to open the container valve. The container valve has functions of both a container valve and a pressure reducing valve, has the good sealing effect, can adjust pressure of starting gas to a set value as required, and is flexible and reliable to open.

Description

technical field [0001] The invention belongs to the field of gas fire extinguishing equipment, in particular to a constant pressure container valve. Background technique [0002] In the external storage pressure automatic fire extinguishing system, due to the limited pressure of the fire extinguishing agent bottle group, the nitrogen gas needs to enter the fire extinguishing agent bottle group through the pressure reducing valve to provide constant pressure power for the fire extinguishing system; when the fire extinguishing agent bottle group is not working, the pressure reducing valve In the closed state, there should be no air bubble leakage. The existing domestic similar product container valve and pressure reducing valve exist at the same time, which wastes space, and the pressure value is not adjustable, so it cannot adapt to fire extinguishing agent bottle sets with different reloading quantities, and cannot guarantee the safety of fire extinguishing agent bottle sets...
