Description

Technical Field

[0001] This application relates to the field of gate valves, and more specifically, to a gas manifold angle valve. Background Technology

[0002] Gas manifolds are devices designed to improve work efficiency and safety by centralizing individual gas sources at single gas consumption points. They aggregate multiple gas containers, such as high-pressure cylinders and cryogenic Dewar flasks, to achieve centralized gas supply. Typically installed in independent buildings or adjacent to factory buildings, manifolds reduce the frequency of cylinder changes, decrease worker workload and save labor costs. Centralized management of high-pressure gases reduces safety hazards, saves space, and facilitates better gas management. Gas manifolds are suitable for enterprises with high gas consumption. The principle involves inputting bottled gas into the main manifold pipeline via clamps and hoses, where it is depressurized, regulated, and then transported to the user site. They are widely used in hospitals, chemical plants, welding facilities, electronics factories, and research institutions.

[0003] Existing compressed gas (oxygen, nitrogen, carbon dioxide, etc.) manifolds with angle valve gas cylinders are all installed vertically, with one end of a high-pressure hose connected to the side and the other end connected to the high-pressure gas cylinder. According to the structural characteristics of the angle valve, the vertical lower end is the valve's inlet, i.e., below the valve disc, and the side end is the outlet, i.e., above the valve disc. However, the current installation method involves the gas cylinder being connected to the side interface above the valve disc via a high-pressure hose, and then entering the manifold below the valve disc. This installation direction is incorrect compared to the medium direction of the shut-off valve. When the valve is opened, the back pressure above the valve disc is too high. The right-angle shut-off valve must be closed every time the gas cylinder is replaced, shortening the valve's lifespan, and the high-pressure hose is bent and drooping.

[0004] A gas manifold angle valve with a high-pressure hose drooping under zero gravity is now provided. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a gas manifold valve, comprising: a high-pressure inlet hose; a cylinder ball head disposed at the bottom of the high-pressure inlet hose for connecting to a cylinder; a right-angle shut-off valve connected to the high-pressure inlet hose; a high-pressure connector disposed between the high-pressure inlet hose and the right-angle shut-off valve; a check valve connector disposed on the right-angle shut-off valve; a check valve core disposed within the check valve connector; a manifold reducing tee connected to the check valve connector; and two manifolds connected to both ends of the manifold reducing tee.

[0007] A check seal ring is provided between the check valve core and the right-angle stop valve.

[0008] A check spring is provided between the right-angle stop valve and the check valve core.

[0009] The high-pressure air intake hose is a corrugated hose.

[0010] The check valve connector is threadedly connected to the right-angle stop valve.

[0011] The manifold reducing tee is threadedly connected to the check valve connector.

[0012] By incorporating a check valve core, check valve connector, check spring, and check seal ring, when an empty cylinder is replaced, the remaining gas in the manifold automatically reverses and closes the valve through the check seal ring under the action of the check spring, eliminating the need to close the right-angle stop valve and extending its service life. This design is simple in structure, low in cost, conforms to the media flow direction, and prevents the high-pressure inlet hose from sagging due to gravity. The invention is easy to operate and install. The core check valve device consists of a check valve core, check valve connector, check spring, and check seal ring. High-pressure gas enters through the inlet port of the right-angle stop valve, and the outlet port of the right-angle stop valve corresponds to the check valve device, which in turn corresponds to the manifold reducing tee, conforming to the media flow direction of the right-angle stop valve. Furthermore, this invention is not limited to the above embodiment and can have many variations.

[0013] In some implementations, a check seal ring is provided between the check valve core and the right-angle shut-off valve.

[0014] The beneficial effects of this application are as follows:

[0015] 1. By setting a check valve core, check valve connector, check spring, and check seal ring, when the empty bottle is replaced, the remaining gas in the manifold will automatically reverse and close the valve through the check seal ring under the action of the check spring, without the need to close the right-angle stop valve, thus extending the service life of the right-angle stop valve. This results in a simple structure, low cost, conformity to the medium flow direction, and no gravity-induced sag of the high-pressure air inlet hose.

[0016] 2. The core check valve device consists of a check valve core, a check valve connector, a check spring, and a check sealing ring. High-pressure gas enters the inlet of the right-angle stop valve, and the outlet of the right-angle stop valve corresponds to the check valve device, which in turn corresponds to the manifold reducing tee, conforming to the medium flow direction of the right-angle stop valve. Furthermore, this utility model is not limited to the above embodiment and can have many variations. Attached Figure Description
