Description

Quick-connecting valve

Technical field

The utility model relates to a kind of valve, particularly a Quick connected ball valve.

Background technique

Existing ball valve is made of valve body, is provided with valve ball in the valve body, is connected with on the valve ball to be used to drive the valve rod that valve ball rotates, described valve rod top extends to the valve body outside, and handle is installed, can drive valve ball by handle with sleeve thus and rotate, and then realize the unlatching of valve or close.

For realizing installation or the connection of valve on pipeline, described valve body is provided with and is used for mouthpiece, described mouthpiece can connect with pipeline or nut by engage thread, a kind of linkage structure comparatively easily is at the mouthpiece place of valve body a seal ring to be set, and the last nut that spins, described seal ring is between the end face of the end face of described mouthpiece and described nut, during installation pipe fitting is inserted mouthpiece, screw nut, seal ring is out of shape under the extruding of nut, the pipe fitting that inserts is stepped up, and the gap of joint is sealed, realized the fixedly connected and sealing between the Valves and Fittings thus simultaneously.But, convenient much although the Placement of this valve connects with respect to regular screw threads, still need to screw nut, do not meet the requirement that people connect fast.

The model utility content

For overcoming the above-mentioned defective of prior art, the utility model provides a kind of quick-connecting valve, adopts this valve, can couple together with pipe fitting quickly and easily.

The utility model realizes that the technological scheme of above-mentioned purpose is: a kind of quick-connecting valve, comprise valve body, and described valve body is provided with mouthpiece, and described mouthpiece is provided with can realize the fast connected components of the pipeline that connects with the pipe fitting insertion.

The beneficial effects of the utility model are: owing to the mouthpiece at valve is provided with the pipe fitting insertion can be realized the fast connected components of the pipeline that connects, therefore when this valve is installed, as long as pipe fitting is inserted its mouthpiece, just can realize the connection of valve with pipe fitting, do not need again operations such as turn nut.

Embodiment

Referring to Fig. 1-Fig. 3, the utility model provides a kind of quick-connecting valve, comprises valve body 2, and described valve body is provided with mouthpiece 9, and described mouthpiece is provided with can realize the fast connected components of the pipeline that connects with the pipe fitting insertion.

The fast connected components of described pipeline can comprise elastic packing Fig. 3, jump ring 7, clamping cap 4 and sleeve 5, described mouthpiece inwall is from inside to outside the first annular stage and the second annular stage of hole enlargement successively, described elastic seal ring is positioned at hole enlargement place of first stage, described jump ring is positioned at hole enlargement place of second stage, described sleeve be positioned at described mouthpiece axially on, described clamping cap is first stage of undergauge and second stage successively from inside to outside, fixedly connected with mouthpiece, usually can adopt thread connecting mode to connect, described clamping cap inboard is provided with internal thread, the described mouthpiece outside is provided with the outside thread supporting with it, the end face of first stage of described clamping cap is connected with the direct or indirect pressure of the body of described jump ring, both passed through the mode of directly contact or mediate contact, give jump ring with propagation of pressure, the end face retaining of described clamping cap second stage is in the flange outer sides at described sleeve internal orifice place, the body 7.1 of described jump ring is provided with some oblique dops that extend internally 7.2, when pipe fitting is inserted described mouthpiece in sleeve, because the circumference at the place, dop end of described jump ring is less than the external diameter of described pipe fitting, described elastic seal ring internal diameter is also less than the external diameter of described pipe fitting, the pipe fitting that inserts with dop and elastic seal ring to external pressure, cause the elastic strain of dop and elastic seal ring, make the dop end tightly be stuck on the outer wall of pipe fitting, elastic seal ring is then lived pipe fitting with the clearance seal between the mouthpiece, if the pipe fitting that inserts is subjected to outside power or has the tendency that outwards moves, because dop is oblique, can tightly block pipe fitting can not outwards move it, realized pipe fitting fixedly connected with valve thus, realized also that pipe fitting is with the sealing between the valve interface pipe simultaneously.

The inboard of described jump ring body can also be provided with an annular back cushion 8 that is positioned at described mouthpiece inwall second stage hole enlargement place, its objective is to fill described jump ring with the gap between the end face of described mouthpiece second stage, so that clamping cap compresses jump ring.Simultaneously, the inwardly protruded part of described back cushion inboard contacts with described elastic seal ring or keeps off the outside at elastic seal ring, so that give described elastic seal ring with the propagation of pressure of clamping cap or form restriction to elastic seal ring, when elastic seal ring is subjected to the pipe fitting pressure distortion, can limit the expansion of elastic seal ring on mouthpiece is axial, guarantee the elastic packing power that elastic seal ring directly makes progress at mouthpiece.

Be provided with the lining 6 of a coaxial tubulose in the described mouthpiece, the inner end of described lining is provided with the flange that radially extends, the inner end end face contacts with the annular protrusion end face with location on the described mouthpiece inwall, formation is to the location of lining, when jointed tubular workpieces inserts outside simultaneously, the inner end of external pipe fitting is stopped by lining inner end end face, forms the location of external jointed tubular workpieces.

The external diameter of described lining can hold the gap that pipe fitting inserts less than the internal diameter of described sleeve with leaving between the described sleeve, and when jointed tubular workpieces inserted outside thus, external pipe fitting was inserted between sleeve and the lining, helps the fixing of external pipe fitting.

The outer end end face of described lining can be the external conical shape conical surface, so that pipe fitting inserts.

Described sleeve outer end end face can be the inner conical conical surface, so that pipe fitting inserts.

The outer end of described lining can be positioned at described sleeve, also can extend to outside the described sleeve.

Described sleeve can be the rigid plastics sleeve, and described elastic seal ring can be a rubber o-ring, and described jump ring can be the metal jump ring that metal clips is made, and described back cushion can be the rigid plastics back cushion.

Described valve body can be a ball valve body, is provided with valve ball in the valve body, is connected with on the valve ball to be used to drive the valve rod that valve ball rotates, described valve rod top extends to the valve body outside, and handle is installed, can drive valve ball by handle with sleeve thus and rotate, and then realize the unlatching of valve or close.

Described valve body also can be the valve body of the valve of other arbitrary forms, to be adapted to the valve of various different structures.

The fast connected components of described pipeline also can adopt the fast connected components of pipeline of other any suitable.
