Abstract
The utility model relates to a pipeline gas self-closing valve. The pipeline gas self-closing valve comprises an upper cover, a lower cover and a valve body, wherein a gas inlet and a gas outlet are formed on both ends of the valve body; a valve port is formed on the middle part of the valve body; a vent hole is formed on one side of the valve body; a diaphragm is arranged between the valve body and the valve cover; a permanent magnetic alloy is arranged on the valve body; a core rod is arranged in the valve body; and a high-pressure seal sheet and an iron sheet are arranged at the bottom of the core rod. When the gas pressure in the pipeline is larger than or smaller than the set pressure, the self-closing valve can automatically close the gas pipe based on the action of magnetic field. The self-closing valve mounted in such a manner that the gas inlet and the gas outlet are on the same axis can greatly reduce the mounting time and cost and can eliminate the pressure difference between the gas inlet and the gas outlet. The pipeline gas self-closing valve can be used not only for end users but also in the main gas transportation pipelines. The pipeline gas self-closing valve has the advantages of simple structure, safe and reliable operation, convenient use and high reliability, and can greatly improve the gas use safety.
Description
Technical field
The utility model relates to a kind of pipeline gas safety self closing stop valve.
Background technique
In real life, a lot of gas valves are arranged, its complex structure, difficulty is installed, the cost height, and speed of response is slow, and closure effect is not good, poor reliability, easily cause potential safety hazard, the closing automatically of uncontrollable valve when the flexible pipe that superpressure air feed and hypotony occur, stop the supple of gas or steam or connect gas appliance when gas pipeline leaks air suddenly simultaneously caused gas leakage, very easily accidents such as initiation fire, blast, poisoning are brought very big danger to the user.
The model utility content
The purpose of this utility model is to overcome the problem that exists in the background technique, and a kind of simple and practical, safe and reliable pipeline gas self closing stop valve is provided, and closes gas pipeline when it utilizes the action of a magnetic field to control the high low pressure state.
The purpose of this utility model realizes with following technical proposals: a kind of pipeline gas safety self closing stop valve, comprise loam cake (3), lower cover (11) and valve body (7), valve body (7) two ends are provided with inlet end (17) and outlet side (18), valve body (7) middle part is provided with valve port (15), valve port (15) is separated into upper cavity (13) and lower chamber (19) with valve body (7), upper cavity (13) one sides of valve body (7) are provided with vent (16), be provided with epithelium (6) between valve body (7) and the valve gap (3), epithelium (6) middle part is provided with iron plate (5), epithelium (6) bottom is provided with sealing gasket (14), valve body (7) is gone up and the interior iron plate of epithelium (6) (5) corresponding position is provided with permanent magnetic alloy (8), the interior epithelium of valve body (7) (6) middle part is provided with core bar (2), core bar (2) top is stretched out loam cake (3) part and is provided with handle (1), core bar (2) middle part is provided with boss (12), be provided with high-pressure regulation sheet (4) in the loam cake (3), high-pressure regulation sheet (4) one ends are near core bar (2), and core bar (2) bottom is provided with high pressure mounting (9) and iron plate (10).
The utlity model has following advantage: when gaseous-pressure in the pipeline reaches less than setting pressure greater than setting pressure, the utility model utilizes the action of a magnetic field to close gas pipeline automatically, can effectively prevent to reveal because of the caused combustion gas of abnormal conditions the generation of accidents such as the fire that causes, blast, poisoning.The utility model adopts inlet end and the mounting type of outlet side on same axis, installation time and expense have been reduced significantly, eliminated the pressure difference of inlet end and outlet side simultaneously, it not only can use the terminal use, also can use in main air delivering pipeline.The utility model is simple in structure, and is safe and reliable, easy to use, and the reliability height has improved the Security that combustion gas is used greatly.

Embodiment
As shown in Figure 1, a kind of pipeline gas safety self closing stop valve, comprise loam cake (3), lower cover (11) and valve body (7), valve body (7) two ends are provided with inlet end (17) and outlet side (18), valve body (7) middle part is provided with valve port (15), valve port (15) is separated into upper cavity (13) and lower chamber (19) with valve body (7), upper cavity (13) one sides of valve body (7) are provided with vent (16), be provided with epithelium (6) between valve body (7) and the valve gap (3), epithelium (6) middle part is provided with iron plate (5), epithelium (6) bottom is provided with sealing gasket (14), valve body (7) is gone up and the interior iron plate of epithelium (6) (5) corresponding position is provided with permanent magnetic alloy (8), the interior epithelium of valve body (7) (6) middle part is provided with core bar (2), core bar (2) top is stretched out loam cake (3) part and is provided with handle (1), and core bar (2) middle part is provided with boss (12), is provided with high-pressure regulation sheet (4) in the loam cake (3), high-pressure regulation sheet (4) one ends are near core bar (2), and core bar (2) bottom is provided with high pressure mounting (9) and iron plate (10).
The utility model working procedure is as follows:
1, during original state, upper and lower cavity in the valve body (7) (13,19) internal pressure is zero, epithelium (6) and embedded iron plate (5) in the upper cavity (13) are descending under the action of a magnetic field of permanent magnetic alloy (8), sealing gasket (14) blocks valve port (15), at this moment, upper cavity (13) is isolated with lower chamber (19), and no combustion gas is passed through in the valve body (7).
When 2, normally using, the blue look graduation line that (1) mention to the core bar (2) of will shaking hands exposes, boss (12) on core bar this moment (2) is blocked up route by high-pressure regulation sheet (4), simultaneously manifold pressure makes epithelium (6) and sealing gasket (14) up, valve port (15) is opened, pressure gas enters in the valve body (7), and this state is a normal working.
3, when the incoming pressure of combustion gas going up in limited time greater than the normal operating pressure of setting, epithelium (6) under the effect of pressure with up, the boss (12) that drives on the core bar (2) backs down high-pressure regulation sheet (4), red graduation line on the core bar (2) exposes, core bar (2) is pulled to valve port (15) with high pressure mounting (9), and with valve port (15) sealing, upper and lower cavity (13,19) is isolated, no combustion gas is passed through in the valve body (7), and be the high pressure closed state this moment.When the high pressure closed state; when no external force is done the time spent; high pressure mounting (9) is adsorbed on valve port (15) and locates; closed state can not change; can not change and move, upper and lower cavity is isolated, in the time of can guaranteeing in the room nobody like this with manifold pressure; combustion gas can not revealed, thereby reach protection user purpose of safety.After abnormal state disappears, when needing proper functioning, core bar (2) can be pushed back to blue look graduation line and expose, the operation of proceeding proper functioning gets final product.When the utility model must have certain pressure to exist, be placed on normal working manually in pipeline.
4, when normal working, when gaseous-pressure during less than the working pressure set, such as: stop the supple of gas or steam, gaseous-pressure is unusual, gas appliance takes off pipe, pipeline breakage etc., iron plate (5) in the epithelium (6) is descending under the action of a magnetic field, drive sealing gasket (14) the sealing valve port (15) on the epithelium (6), upper cavity (13) and lower chamber (15) are isolated.Be the low pressure closed condition this moment, and this state promptly is an original state.
