Abstract
The invented pipe fitting self-sealing joint is composd of valve component and shell body, and is used for joining and installing pipe line, the valve component in shell body is under normally closed state, durnig the process of using, when the outlet end and pipe fitting (for example, tap) inlet end is communicated, the valve autoamtically opens and forms pipeline passage; when the outlet end and pipe fitting (for example, tap) is separated, the valve component closes and block, the pipeline passage.
Description
The present invention relates to a kind of being installed on the pipeline, and can realize the pipe fitting self-sealing joint device of opening and closing as required.
Joint commonly used on the pipeline normally couples together pipe fitting, with the pipe fitting transit system of realizing that it is complete.But; the pipe-line system necessary total threshold switch of first shutdown system or branch roads system main switch when keeping in repair or change branch system with common joint connection; can change or repair after laying down the pipeline medium; so usually can influence the proper functioning of other branch road on the same branch road, also can cause the loss of branch road medium simultaneously and waste resource.
In order to address this problem, purpose of the present invention just provides a kind of pipe fitting joint function that possesses, and the piecing devices that can open and close voluntarily as required.
The object of the present invention is achieved like this: a check valve is installed in the inside at pipe fitting joint, and valve is in normally off.With after this device is connected, valve is opened automatically at pipe fitting, and pipeline is in channel status; When pipe fitting with after the outlet end of this device separates, valve is closed voluntarily, blocking-up pipeline system pass.
The present invention is because only need newly be provided with a check valve that can seal voluntarily in common tube joint inside, so its structure is comparatively simple, the starting point is to solve the self-styled problem of joint simultaneously, rather than self-styled form, so no matter be ball face sealing, end face seal, conical surface seal all can be satisfied its requirement, and the various seal form of installing inner check valve all constitute one of feature of the present invention.
Concrete structure of the present invention is provided by following several frequently seen embodiment and accompanying drawing thereof.
Fig. 1 is several embodiments' a erection drawing.
Detail and working condition below in conjunction with Fig. 1 detail explanation embodiment.
In Fig. 1, each embodiment all has a housing (1), a valve member (2) and a spring (3), and spring (3) is enclosed within on the slide bar of valve member (2).Generally, spring force makes the spool on the valve member (2) seal housing (a 1) left side (import) port, and each embodiment all is in normally off.
When pipe fitting (as water tap) entrance point is connected with the embodiment right side (outlet) end, because the entrance point of pipe fitting (as water tap) withstands the right-hand member and the pressure spring (3) of valve assembly (2), make valve assembly (2) be moved to the left a segment distance, housing (1) endoporus is opened, and pipeline is in unimpeded state; When pipe fitting (water tap) maintenance or when changing, pipe fitting (as water tap) separates with embodiment's outlet end, valve assembly (2) segment distance that under the effect of spring (3), moves right, and valve assembly (2) is blocked housing (1) endoporus, and pipeline is blocked.
In embodiment a, b, c, a left side (import) end of housing (1) all has outside thread, right (outlet) end all has internal thread, the Dimensions of these screw threads and pipe fitting screw thread is complementary, its entrance point and branch pipeline connector are (as tee union, cross fitting, heading joint is first-class) outlet end be connected, outlet end then directly is connected with pipe fitting (as water tap) entrance point.
In embodiment d, e, f, the left and right port of housing (1) all has internal thread, its specification and pipe fitting thread size are complementary, they mainly are installed on the direct piping, its left side (import) end is directly installed on the pipe fitting outlet end, and right (outlet) end then is directly installed on pipe fitting (water tap) entrance point.
In each embodiment of Fig. 1, because valve assembly (2) is an assembly parts, can resolve into parts such as the described seal A of Fig. 2, slide bar B and spring seat C according to the production technology needs, by bonding, welding or mode such as be threaded are made valve assembly (2), and with housing (1) and spring (3) formation various embodiments of the present invention.
According to Fig. 2, the feature of seal A is the corresponding to circular cone of inside circular cone endoporus that right-hand member has a size and housing (1), the one cylinder step that is slightly larger than circular cone is arranged at the bottom of circular cone (left end), the two closely fuses and constitutes seal A, its size and housing (1) conical bore matches, and constitutes embodiment's sealing important parts; Slide bar B plays guiding and slip effect, it is characterized in that a cylinder polished rod or a light pipe, as required, have the aperture of being convenient to media flow on the light pipe of Fig. 1 c Fig. 1 f, there is the guiding step of one " vehicle steering wheel " shape at the polished rod middle part of Fig. 1 a, Fig. 1 d, and the excircle dimension of step and housing (1) match.In Fig. 1 b and Fig. 1 e, the structure of " vehicle steering wheel " shape then is to be connected as a single entity with housing (1), polished rod slides in the heart hole therein, spring seat C makes spring (3) attached on the slide bar, in Fig. 1 c and Fig. 1 f, spring seat is a circular boss and light pipe outer cylinder (right bottom) face links together, and then is " vehicle steering wheel " shape attached to the polished rod root in all the other embodiments.
The seal feature of valve assembly (2) is except that above-mentioned, and the described ball face sealing of Fig. 3, end face seal all are one of embodiment of the invention.
Claims (4)
1, a kind of nonspill coupling device that is used for piping erection.This device is made up of housing (1), spool (2) and spring (3).Spool is free to slide in enclosure interior, and spring housing under the effect of spring force, is characterized in that spool enclosing housing endoporus under usual condition on spool.The entrance point of this device and outlet end have the screw thread that is complementary when being connected with pipe fitting.If when the outlet end of this device is installed corresponding pipe fitting, it is characterized in that pipe fitting promotes spool (2) and is moved to the left a segment distance and pressure spring (3), housing (1) endoporus is opened; After unloading lower outlet end respective tube part, it is characterized in that spring (3) drives spool (2) segment distance that moves right, housing (1) endoporus is closed.
2, device according to claim 1 is characterized in that a step circular hole and a conical bore arranged in the housing (1), and conical bore constitutes the closed hole of self-sealing joint.
