Description
Technical field
The utility model relates to fluid control device field, is specifically related to a kind of telescopic table pre-gate valve.
Background technique
Gate valve is widely used in industrial production and daily life, existing gate valve in the time installing and using, the length of regulation valve body according to actual needs, using scope is greatly limited.
In prior art, application number is 201020587298.8 Chinese patent, a kind of soft seal threaded-connection telescopic gate valve is disclosed, as shown in Figure 1, the waterexit end inner chamber of valve body 1 is set with movable joint 6, movable joint 6 can move freely at inner chamber, between movable joint 6 and valve body 1, seals by rubber ring 2 and pad 3, is provided with valve body lock nut 7 and carries out spacing to movable joint 6 outside movable joint 6.The gate valve installation step of this kind of structure is loaded down with trivial details, processing difficulties, thereby rubber ring 2 and pad 3 are squeezed and easily produce deformation and affect its sealability, and it does not possess the function that prevents that movable joint 6 from extracting from valve body 1 inner chamber simultaneously, has inconvenience in assembling.
Model utility content
The deficiency existing for prior art, the utility model provides a kind of and has processed simply, assembled telescopic table pre-gate valve simple and easy, good seal performance.
For solving the problems of the technologies described above, the telescopic table pre-gate valve of one that the utility model provides, comprise valve body, valve gap and screw mandrel, described screw mandrel is axially fixed on valve gap by stopping cap, screw mandrel lower end is provided with flashboard, filler is equipped with in described screw mandrel and valve gap joint, and copper backing is set on it, and is socketed the fastening filler of lock nut; Chrysanthemum handwheel is equipped with in described screw mandrel upper end, can drive screw mandrel to rotate, and both are fixed by Anti-slip nut; Described valve body waterexit end inner chamber is set with adapter, described adapter can be slided along inner chamber, the end of described adapter waterexit end is connected with loose joint nut, in loose joint nut, be provided with rubber sheet gasket, described valve body waterexit end inner chamber is provided with draw-in groove, interior snap ring is installed in draw-in groove, and described interior snap ring matches with taking over the upper limited step arranging, and described adapter feed-water end outer surface is provided with O type circle.
Preferably, while assembling between described valve gap and described valve body, be added with hollow pad.
Preferably, described O type circle is 2.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: in the time assembling, have more flexibility because the scalable performance of taking over makes gate valve, simultaneously, snap ring is fixing takes over, and match with limited step, restriction is taken over and is skidded off from valve body, simple in structure easy to use, and the structure of two O type circles is ensureing that gate valve is in the sealability of adapter and valve body joint, also reduce valve body lock nut, saved material.
