Abstract
A leak-proof self-closing valve, which is composed of a valve body (1), a main slide valve cylinder (2), a main slide valve (3), an end closure (4) and a control slide valve (5). The valve body (1) is composed of a liquid guiding cylinder (11) and a control slide valve cylinder (12). The end with a big hole of the main slide valve cylinder (2) is connected with a nozzle of the valve body liquid guiding cylinder (11) by means of a screw thread (22); a main slide valve plug (32) is arranged in the main slide valve cylinder (2), a pressure spring (6) is covered on a valve rod (31) of the main slide valve plug (32), the end of the valve rod (31) runs through a main slide valve rod hole (13); the end closure (4) which is a cover-shaped body, whose middle part has a hole (41), is fixed on the nozzle of the control slide valve cylinder (12) by a screw thread (42); a control slide valve (52) is arranged in the control slide valve cylinder (12), the one end of a valve rod (51) is arranged in the valve body liquid guiding cylinder (11), and a pressure spring (7) is covered on the another end of the valve rod (51), the end with a pressure spring (7) of the valve rod (51) runs through an end closure hole (41). The utility model has the advantages that the structure is simple, firm and durable with a low cost, in addition, the operation is easy with a perfect seal effect, moreover, the purpose of water-saving can also be realized and the invention can also be used to prevent other liquid or gas-pipelines from leakage.
Description
Technical field
The utility model relates to valve, the valve that can close automatically when particularly cutting off the water.
Background technique
Close the water tap phenomenon of metalling run out for the back that prevents to cut off the water because of forgetting, the someone has invented various leakproof self closing stop valves and has solved this problem, but they or complex structure cost height, or use inconvenience, or not sturdy and durable.
Summary of the invention
The purpose of this utility model provides low, easy to use, the robust leakproof self closing stop valve of a kind of cost simple in structure.
Technical solution of the present utility model is: it is made up of valve body, main slide valve tube, main slide valve, end cap and control guiding valve, valve body is by straight tubular drain tube and laterally be located at the control valve barrel that drain tube middle part communicates with it and constitute, the control valve barrel is provided with the main slide valve valve rod hole in the one side drain tube tube hole, is axially arranged with through hole between main slide valve valve rod hole and the drain drum outer wall; The main slide valve tube is that endoporus is step-like cylindrical shell, and the big nose end of main slide valve tube is provided with main slide valve valve rod nose end nozzle by screw thread and valve body drain tube and links to each other; Main slide valve is made of valve rod and the sliding plug that is fixed on valve rod one end, and the sliding plug of main slide valve is positioned at the main slide valve tube, is with pressure spring on its valve rod, and the valve rod end is through in the main slide valve valve rod hole; End cap is that the middle part is provided with the hole and is fixed on cover-shaped body on the control valve barrel nozzle by screw thread; The control guiding valve is made of valve rod and the sliding plug that is fixed on the valve rod middle part, and the control guiding valve is slided plug and is positioned at the control valve barrel, and one side valve bar is positioned at valve body drain tube, the pressure spring that is with on the opposite side valve rod, and this side valve boom end passes ending cover hole.
Technique effect of the present utility model is: it has low, easy to use, the robust advantage of cost simple in structure, can prevent metalling run out and can reach the purpose of water saving, and it also can be used for other liquid or gas piping anti-leak.
