Background technique
Existing control valve generally includes valve, and a side and the handwheel of the valve rod in the described valve generally all expose in the outside, and valve rod is very long, thus increased control valve integral body take up room.
The model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to reduce taking up room of control valve.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of little control valve that takes up room comprises valve body and valve; Described valve comprises handwheel, interior bar, outer tube, spring and spool; Described spool cooperates rotation to be installed in the valve body, and described outer tube is fixedlyed connected with spool, and described interior bar one side is fixedlyed connected with handwheel; Opposite side comprises step, and described step is installed in the pipe of outer tube and can moves axially, and between bar and the outer tube, the one end contacted with spool in described spring housing was connected on, and the other end contacts with step; The bottom surface of described step cooperates clamping with spool, and the end face of described step cooperates clamping with outer tube.
Described spool includes groove, and the bottom surface of described step includes two grabs, is provided with the gap between described two grabs, and described grab cooperates clamping with groove.
It is the radial ringed double wedge that is distributed on the step end face in axle center with interior bar that the end face of described step is provided with at least one, and it is the radial ringed draw-in groove that is distributed in the outer tube pipe in axle center with the outer tube that described outer tube includes at least one; Described double wedge cooperates clamping with draw-in groove.
Described double wedge and draw-in groove are 4.
(3) beneficial effect
A kind of little control valve that takes up room of the present utility model, by valve rod being arranged to interior bar and the outer tube of shrinking structure, interior bar is contracted in the outer tube, and length and the interior bar that can reduce valve rod are connected with handwheel and the outer tube spool are connected, thereby have reduced taking up room of control valve.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of little control valve that takes up room as shown in Figure 1, Figure 2, Figure 3 and Figure 4 comprises valve body 1 and valve 2; Described valve 2 comprises handwheel 3, interior bar 4, outer tube 5, spring 6 and spool 7; Described spool 7 cooperates rotation to be installed in the valve body 1, and described outer tube 5 is fixedlyed connected with spool 7, and described interior bar 4 one sides are fixedlyed connected with handwheel 3; Opposite side comprises step 8, and described step 8 is installed in the pipe of outer tube 5 and can moves axially, thereby realizes flexiblely, reduces shaft length.Between bar 4 and the outer tube 5, the one end contacted with spool 7 in described spring 6 was socketed in, and the other end contacts with step 8; The bottom surface of described step 8 cooperates clamping with spool 7, and this structure is the length after the shortening fixedly, and the end face of described step 8 cooperates clamping with outer tube 5, and by clamping, bar 4 is fixedlyed connected with outer tube 5 in making, thereby makes handwheel 3 control spools 7.
Described spool 7 includes groove 9, and the bottom surface of described step 8 includes two grabs 10, is provided with the gap between described two grabs 10, and described grab 10 cooperates clamping with groove 9, the length after bar 4 shortened in this structure can be fixed.
It is the radial ringed double wedge 11 that is distributed on step 8 end faces in axle center with interior bar 4 that the end face of described step 8 is provided with 4, and it is the radial ringed draw-in groove 12 that is distributed in outer tube 5 pipes in axle center with outer tube 5 that described outer tube 5 includes 4; Described double wedge 11 cooperates clamping with draw-in groove 12, and bar 4 is fixedlyed connected with outer tube 5 in making.
When control valve need shorten, pin handwheel 3 and pass through interior bar 4 to outer tube 5 interior contractions, double wedge 11 and draw-in groove 12 are broken away from, and make fixedly contracted length of grab 10 and groove 9, thereby can reduce taking up room of control valve.
When the valve of control valve need use, will pin handwheel 3 and outwards extend by interior bar 4, grab 10 and groove 9 are broken away from, after grab 10 breaks away from, bar 4 automatically reset in spring 6 bounce-backs drove, and double wedge 11 is stuck in the draw-in groove 12, thereby made handwheel can control spool.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
