Abstract
The utility model discloses buried type stop valve, comprise valve body, valve seat, flap, valve clack cover, lower valve rod, valve gap, anti-turn screw, bearing, Stem Mut, upper valve rod, extension pipe, union (screwed)bonnet (UB, handwheel, lower valve rod is fixed on above flap by flap nut, lower valve rod top is through valve gap, bonnet flange and valve flange are through Bolt Connection, spline in the middle part of lower valve rod, anti-turn screw is fixed on above valve gap, anti-turn screw keys in keyway, lower valve rod head is connected with Stem Mut by T-shaped screw thread, Stem Mut head and upper valve rod pass through, upper valve rod is connected with Stem Mut is castellated, union (screwed)bonnet (UB is threaded with extension pipe, handwheel fork hexagonal is connected with upper valve rod.The utility model upper valve rod only rotates and does not rise, rotate through castellated drive Stem Mut, bolt and nut drives lower valve rod to rise through T-shaped screw thread and antirotation keys, thus realizes the switch of valve, and valve opening moment is little, processing technology simple, upper valve rod and lower valve rod difficult drop-off.
Description
Technical field
The utility model relates to stop valve, particularly relates to buried type stop valve.
Background technique
Existing buried stop valve be above upper valve rod inside, lower end open a rectangle insert connect with lower valve rod, make upper lower valve rod integral elevating by the rotation of handwheel thus realize the switch of the stop valve of buried underground.Traditional buried stop valve also exists and makes upper lower valve rod integral elevating by the rotation of handwheel thus realize the switch of stop valve, opens the problem that moment is larger.
Model utility content
The purpose of this utility model is to provide buried type stop valve, solves traditional buried stop valve in prior art and also exists and make upper lower valve rod integral elevating by the rotation of handwheel thus realize the switch of stop valve, open the problem that moment is larger.
The technological scheme that the utility model adopts is: buried type stop valve, comprise valve body, valve seat, flap, valve clack cover, lower valve rod, valve gap, anti-turn screw, bearing, Stem Mut, upper valve rod, extension pipe, union (screwed)bonnet (UB, handwheel, bonnet flange and valve flange, lower valve rod is fixed on above flap by flap nut, lower valve rod top is through valve gap, bonnet flange and valve flange are through Bolt Connection, spline in the middle part of lower valve rod, anti-turn screw is fixed on above valve gap, anti-turn screw keys in keyway, lower valve rod head is connected with Stem Mut by T-shaped screw thread, Stem Mut head and upper valve rod pass through, upper valve rod is connected with Stem Mut is castellated, union (screwed)bonnet (UB is threaded with extension pipe, handwheel fork hexagonal is connected with upper valve rod.
The utility model compared with prior art tool has the following advantages: upper valve rod only rotates and do not rise, rotate through castellated drive Stem Mut, bolt and nut drives lower valve rod to rise through T-shaped screw thread and antirotation keys, thus realizing the switch of valve, valve opening moment is little, processing technology is simple, upper valve rod and lower valve rod difficult drop-off.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure, 1, valve body; 2, valve seat; 3, flap; 4, valve clack cover; 5, lower valve rod; 6, valve gap; 7, anti-turn screw; 8, bearing; 9, Stem Mut; 10, upper valve rod; 11, extension pipe; 12, union (screwed)bonnet (UB; 13, handwheel.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, buried type stop valve, comprise valve body 1, valve seat 2, flap 3, valve clack cover 4, lower valve rod 5, valve gap 6, anti-turn screw 7, bearing 8, Stem Mut 9, upper valve rod 10, extension pipe 11, union (screwed)bonnet (UB 12, handwheel 13, bonnet flange and valve flange, lower valve rod 5 is fixed on above flap 3 by flap nut 9, lower valve rod 5 top is through valve gap 6, bonnet flange and valve flange are through Bolt Connection, spline in the middle part of lower valve rod 5, anti-turn screw 7 is fixed on above valve gap 6, anti-turn screw 7 keys in keyway, lower valve rod 5 head is connected with Stem Mut 9 by T-shaped screw thread, Stem Mut 9 head and upper valve rod 10 pass through, upper valve rod 10 is connected with Stem Mut 9 is castellated, screw bonnet 6 is threaded with extension pipe 11, handwheel 13 is pitched hexagonal and is connected with upper valve rod 10.
Upper valve rod 10 rotation is not risen, and rotates through castellated drive Stem Mut 9, and bolt and nut 9 drives lower valve rod 5 to rise through T-shaped screw thread and antirotation keys, thus realizes the switch of valve.
The utility model upper valve rod 10 rotation is not risen, and rotates through castellated drive Stem Mut 9, and bolt and nut 9 drives lower valve rod 5 to rise through T-shaped screw thread and antirotation keys, thus realizes the switch of valve.
It should be noted last that, above embodiment is only unrestricted for illustration of the technical solution of the utility model, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in right of the present utility model.
