Description

Valve and gas cylinder pressure vessel

Technical Field

The invention belongs to the field of valves, and particularly relates to a valve and a gas cylinder pressure container.

Background

Valves are plumbing accessories used to open and close a pipe, control flow direction, regulate and control parameters of the transport medium (temperature, pressure and flow). According to their function, they can be classified into shut-off valves, check valves, regulating valves, and the like.

The valve is a control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like. Valves used in fluid control systems range in variety and size from the simplest shut-off valves to the variety of valves used in extremely complex autonomous systems.

The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valves are further classified into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves, etc. according to the material.

For a pressure container, valve control is of great importance, the on-off of the existing valve control depends on manpower, labor is wasted, standardization is lost, and management is difficult.

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 obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.

As shown in fig. 1-2, the present embodiment provides a valve, comprising: the air inlet 1 is communicated with an external air source; the gas outlet 2 is communicated with an external gas storage container, the gas outlet 2 is communicated with the gas inlet 1 through a gas passage 3, a valve core 4 capable of moving along the gas passage 3 is arranged in the gas passage 3, and a matching mechanism 41 is arranged on the valve core 4; and

the lock mechanism 5, the lock mechanism 5 can form the position interference to the cooperating mechanism 41 under the external power; when the locking mechanism 5 does not form position interference on the matching mechanism 41, the gas pressure in the gas source can push the valve core 4, so that the bottom of the valve core 4 presses the gas outlet 2; when the lock mechanism 5 forms positional interference with the engagement mechanism 41, the bottom of the valve element 4 is separated from the air outlet 2. The position interference means that the locking mechanism can give mechanical stress to the matching mechanism, so that the original stroke of the valve core is blocked, the original position of the valve core which can be reached cannot be reached, and the interference of the locking mechanism is received.

The engagement mechanism 41 is a recessed structure provided on the side wall of the valve element 4. The valve core 4 is of a cylindrical structure, and the concave structure is equivalent to turning a concave circular ring on the cylindrical structure. The valve core 4 is formed by connecting an upper concave structure and a lower closed structure in a threaded mode. The concave structure is provided with a vent hole, and the cross section of the closed structure is shown in figure 2. The gas in the gas source passes through the vent hole and then gives a certain pressure to the cross section, and the pressure is enough to push the valve core 4 to descend so as to seal the gas outlet. If the valve core 4 is fixed by the lock mechanism (i.e. the position is interfered), the gas pressure cannot push the valve core 4, and the gas flows into the gas outlet from 4 arrows (i.e. the closed structure and the reserved cavity on the side wall of the gas passage) in fig. 2.

The lock mechanism 5 comprises a post 51 which can be inserted into the recess, the post 51 being slidably disposed within a cavity in which a guide pin 52 is fixedly disposed.

The guide pin 52 is a permanent magnet, the pillar 51 is a soft magnet, and when a magnetic field is applied to the outside of the chamber, the pillar 51 can generate a magnetic field which repels the guide pin 52, so that one end of the pillar 51 slidably protrudes into the concave structure.
