Abstract
The utility model discloses a kind of pipeline self closing stop valve, comprises valve body, valve rod, seal ring and spring, and described valve rod is arranged in described valve body, is provided with boss in described valve body; Described valve rod is arranged in described boss; Described valve rod one end is provided with the first limiting board, and the other end is provided with the second limiting board; Described spring is arranged between boss and the first limiting board; Described seal ring is arranged between described second limiting board and described boss.The utility model structure is simple, easy to use, the external device such as angle valve, outlet valve on convenient and swift replacing pipeline.
Description
Technical field
The utility model relates to a kind of pipe-line equipment, particularly relates to a kind of pipeline self closing stop valve.
Background technique
When house ornamentation line arrangement, there is meeting spare interface on pipeline, then use plug to be blocked by joint, then carry out suppressing test, also boiled water room main valve must cut out after completing test, twist off plug and connect the equipment such as angle valve again, very not convenient, need to design a kind of self closing stop valve, both directly plug can be regarded, again can as the transitional facility on pipeline, screw on external device time realize normal open state, can plug be regarded again after laying down equipment.Angle valve has been broken in the future, and also need not close community main valve, directly lay down, pipeline is closed automatically, directly changes angle valve.Equally at the valve for radiator of indoor use, the equipment such as heat exchange TVV Thermal Vent Valve also need such equipment.
Model utility content
The purpose of this utility model is: in order to solve the problem, and provides the pipeline self closing stop valve that a kind of structure is simple, easy to use, the device such as angle valve, outlet valve on convenient and swift replacing pipeline.
To achieve these goals, the technical solution of the utility model is:
A kind of pipeline self closing stop valve, comprise valve body, valve rod, seal ring and spring, described valve rod is arranged in described valve body, is provided with boss in described valve body; Described valve rod is arranged in described boss; Described valve rod one end is provided with the first limiting board, and the other end is provided with the second limiting board; Described spring is arranged between boss and the first limiting board; Described seal ring is arranged between described second limiting board and described boss.
Further, described valve body is divided into the first cavity and the second cavity by described boss.
Further, internal thread is provided with in described first cavity; The conical surface is provided with in described second cavity.
Further, described seal ring is arranged in described second cavity; Described spring is arranged in described first cavity.
Further, described valve body is provided with outside thread.
The utility model is owing to have employed above-mentioned technology, and the good effect making it compared with prior art to have is:
The utility model is provided with valve rod and spring in valve body, utilizes the elasticity of spring to realize the function of Self-resetting, is provided with the second limiting board on valve rod simultaneously, sealing cone can be close to by crush seal circle, reach sealing effect, thus realize function of self closing, now import and outlet disconnect, plug can be made use, when valve rod pushes up by external device to the right time, seal ring and the conical surface are offed normal, and now import and outlet communicate, pipeline is opened, and what now connect is externally provided with and can normally uses.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model pipeline self closing stop valve;
Fig. 2 is the valve body structure schematic diagram of the utility model pipeline self closing stop valve;
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 and Fig. 2, a kind of pipeline self closing stop valve, comprise valve body 1, valve rod 2, seal ring 3 and spring 5, described valve rod 2 is arranged in described valve body 1, is provided with boss 12 in described valve body 1; Described valve rod 2 is arranged in described boss 12; Described valve rod 2 one end is provided with the first limiting board 21, and the other end is provided with the second limiting board 22; Described spring 5 is arranged between boss 12 and the first limiting board 21; Described seal ring 3 is arranged between described second limiting board 22 and described boss 12; Owing to being provided with valve rod 2 and spring 5 in valve body 1, the elasticity of spring 5 is utilized to realize the function of Self-resetting, on valve rod 2, be provided with the second limiting board 22 simultaneously, sealing surface can be close to by crush seal circle 3, reach sealing effect, thus realize function of self closing, now import and outlet disconnect, plug can be made use, when valve rod 2 pushes up by the external device such as angle valve, outlet valve to the right time, seal ring 3 and sealing surface are offed normal, and now import and outlet communicate, pipeline is opened, and the external device now connected is provided with and just can normally uses.
Preferably, described valve body 1 is divided into the first cavity 6 and the second cavity 7 by described boss 12.
Preferably, internal thread 11 is provided with in described first cavity 6; Be provided with the conical surface 14 in described second cavity 7, utilize conical surface seal to realize preferably sealing effect.
Preferably, described seal ring 3 is arranged in described second cavity 7; Described spring 5 is arranged in described first cavity 6.
Preferably, described valve body 1 is provided with outside thread 13, is convenient to be connected with the joint on pipeline.
Pipeline self closing stop valve not can be used only on indoor water pipe, but also can be arranged on heat exchanger and radiator, pipe laying self closing stop valve on indoor water pipe, when needing to change angle valve, the trouble of open and close boiled water room main valve repeatedly can be saved, save a large amount of time, pipe laying self closing stop valve on heat exchanger and radiator, in time not needing to connect outlet valve, can use as plug, when needs outlet valve, only outlet valve directly need be screwed on, just can work, convenient and swift.
In sum, the utility model structure is simple, easy to use, the external device such as angle valve, outlet valve on convenient and swift replacing pipeline.
