Abstract
A fast connecting ball valve comprises a valve body, a valve element, a sealing gasket, a valve rod and a compressing cap. The axial opening of the valve body is connected with a valve cover, the valve element is arranged in a cavity formed by the valve body and the valve cover, the valve rod is arranged in the upper cylindrical cavity of the valve body, a sealing ring is arranged between the valve rod and the valve body, the compressing cap is arranged above the sealing ring, the compressing cap is connected to the valve body in a threaded mode, an O-shaped ring is arranged between the valve rod and the compressing cap, external threads and internal chamfers are arranged at the connecting positions of the valve body, the two ends of the valve cover and an external pipeline respectively, a sealing groove and sawtooth-shaped protrusions are also arranged at the connecting positions of the valve body, the two ends of the valve cover and the external pipeline respectively, and the valve body and the two ends of the valve cover can be connected with the external pipeline in a clamping and sleeving mode and in a buckling and pressing mode. The valve rod and the compressing cap are lengthened, threads are machined on the outer circumference of the compressing cap, the valve body can be buried in a wall or buried below a material plate, and the valve can be fixed through nuts. The fast connecting ball valve is convenient to mount, large in application range and capable of being widely applied to water supply pipelines, heating pipelines and gas supply pipelines.
Description
Technical field
The utility model relates to a kind of ball valve, especially a kind of quick connecting ball valve.
Background technique
Current, valve has been widely used in the people to be had in the industrial fields such as field and oil, chemical industry, and particularly in civil area, valve is as controlling component main in residential building water supply, heating, the supply air line.
Traditional tap water pipe line and air delivering pipeline generally adopt metal tube, and the valve that therefore connects at its pipeline adopts thread connecting mode, and this is because the tube wall of metal tube is thicker, can process screw thread at the connecting end of pipe, in order to connect.Along with the development of science and technology and the requirement of national energy-saving consumption reduction and low-carbon (LC) life technical policy, develop the plastic tube alternative metals pipes such as PP, PE, PVC, these pipes should not process screw thread at tube wall, therefore need other Placements.The quick connecting ball valve of prior art and external pipeline be connected with two kinds of forms, a kind of is that cutting ferrule connects, another kind is that fastening-pressing type connects, this two class is connected with characteristics separately, in some occasions, when particularly pipeline keeps in repair, the maintenance man can not determine which kind of mode original connection is, just can know after only having dismounting, this just need to be with the aftermarket attachment of different Placements, for work is made troubles.
Summary of the invention
Technical problem to be solved in the utility model is that provide for the above-mentioned state of the art a kind of both connects with cutting ferrule, the novel quick connecting ball valve of two kinds of linkage structure forms that also connect with fastening-pressing type.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of quick connecting ball valve, comprise valve body, spool, sealing gasket, valve rod, clamping cap, wherein the axially open of valve body is connected with valve gap, spool is arranged in the cavity of valve body and valve gap formation, and valve rod is arranged in the top tubular cavity of valve body, between valve rod and the valve body seal ring is arranged, there is clamping cap the seal ring top, clamping cap is threaded on the valve body, and O shape circle is arranged between valve rod and the clamping cap, is characterized in:
Two ends and external pipeline joint at described valve body and valve gap are respectively equipped with outside thread and interior chamfering, can be connected with the mode of pipeline with cutting ferrule.
As improvement, on the cylindrical of the two ends of described valve body and valve gap and external pipeline joint, also be respectively equipped with seal groove and sawtooth projection, can be connected in the mode of withholding with pipeline.
As improvement, described valve rod lengthens, can be valve installation within the walls or under the floor.
As improvement, described clamping cap also lengthens, and the clamping cap Excircle machining has screw thread, can be fixing on the wall or on the floor valve with nut.
Compared with prior art, the utility model has the advantage of: the two ends of valve body and valve gap and external pipeline joint both be respectively equipped with outside thread and interior chamfering, also be designed with respectively seal groove and sawtooth projection, can adopt cutting ferrule and be connected dual mode and be connected with external pipeline; Valve rod and clamping cap lengthen, and the Excircle machining of clamping cap has screw thread, can be embedded in valve body within the walls or just under the plate, and can be fixed with nut.The utility model is easy for installation, and Applicable scope is large, can be widely used in water supply, heating, the supply air line.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of quick connecting ball valve, comprise valve body 1, spool 4, sealing gasket 3, valve rod 5, clamping cap 7, wherein the axially open of valve body 1 is connected with valve gap 2, and spool 4 is arranged in the cavity of valve body 1 and valve gap 2 formation, and valve rod 5 is arranged in the top tubular cavity of valve body 1, between valve rod 5 and the valve body 1 seal ring 6 is arranged, there is clamping cap 7 seal ring 6 tops, and clamping cap 7 is threaded on the valve body 1, and O shape circle 8 is arranged between valve rod 7 and the clamping cap.Two ends and external pipeline joint at described valve body 1 and valve gap 2 are respectively equipped with outside thread 11 and interior chamfering 12, can be connected with the mode of pipeline with cutting ferrule.On the cylindrical of the two ends of described valve body 1 and valve gap 2 and external pipeline joint, also be respectively equipped with seal groove 21 and sawtooth projection 22, can be connected in the mode of withholding with pipeline.
Described valve rod 5 lengthens, can be valve installation within the walls or under the floor.Described clamping cap 7 also lengthens, and the clamping cap Excircle machining has screw thread 71, can be fixing on the wall or on the floor valve with nut.
During assembling, first the axially open of spool 4 from valve body 1 is assembled to the cavity of valve body 1, then the upper sealing gasket 3 of the rear and front end pad of spool 4 is threaded valve gap 2 fixing; Again the valve rod 5 that two O type circles 8 are housed is placed in the top tubular cavity of valve body, puts again seal ring 6, and be threaded fixing with clamping cap 7.When pipeline is installed, according to actual conditions, adopt cutting ferrule to be connected or the clinching connection with external pipeline.
