(pay attention to：Shown structure in accompanying drawing is simply to illustrate that the signal of inventive features, is not intended to according to shown in accompanying drawing
Structure.)
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1-2, according to Worm type double on and off valve of the present invention, including valve body 4, the valve body 4 in "】”
Type structure, described "】" type structure includes Part I with inner open formula space and second with internal confined space
Part.
Wherein, the Part I with inner open formula space includes upper and lower two corresponding wall portions as shown in Figure 1,
Above-mentioned two wall portion is horizontal-extending out from two ends up and down of the Part II with internal confined space respectively, and
It is consequently formed corresponding structure.
Preferably, the flange hole for fixed valve body 4 is additionally provided with the valve body 4.
Offer feed pipe and discharge pipe on the Part II with internal confined space, wherein feed pipe and
Discharge pipe exists in Part II in the form of through hole.Two through holes as the feed pipe and discharge pipe are worn
Two end faces up and down of Part II and perpendicular to upper and lower two end faces, therefore the two through holes are parallel.
Preferably, the exit of feed pipe and discharge pipe is helicitic texture, for being spirally connected with the pipeline of outside.And
And the aperture of feed pipe and discharge pipe can be asymmetric.
There is the blind hole that a level opens up at the inside midline position of Part II, for accommodating valve element 9.The valve element
9 be in shaft-like structure, and valve element 9 is arranged in the blind hole, is coordinated with valve body 4 for gap.Corresponding to feed pipe and discharge pipe,
Be provided with two through holes corresponding with feed pipe and discharge pipe on valve element 9, and around two through holes on set it is close
Big envelope 8.
Preferably, sealing shroud 8 is arranged on Part II and is surrounded the seal groove that the periphery of valve element 9 opens up using the form of O-ring
It is interior.By the sealing shroud 8, when can prevent that valve element 9 from moving axially, material is from the gap between valve element 9 and Part II
Overflow.
When two through holes on valve element 9 and feed pipe and discharge pipe to it is corresponding when can then realize feed pipe and go out
The connection of pipe material；Otherwise, when two through holes on valve element 9 and feed pipe and discharge pipe not to it is corresponding when then feed pipe
It can not be connected with discharge pipe.Therefore, two through hole phases on valve element 9 can be changed by changing the axial location of valve element 9
For feed pipe and the correspondence position of discharge pipe, so as to change the connected state of feed pipe and discharge pipe.
In addition, one section of axle portion that valve element 9 stretches out Part II is located in the open space of Part I, the wherein axle portion
End periphery sets worm screw 5, and the opening position do not interfered with worm screw 5 on valve element 9 sets a lug boss, the institute outside valve element 9
State and a compression spring 7 is arranged between lug boss and the perpendicular end surface of Part II.By compression spring 7, valve element 9 can be applied
