Abstract
The utility model discloses a butterfly valve, comprising a valve body, a valve plate in the valve body, a valve rod fixedly connected with the valve plate and a handle connected with one end of the valve rod to drive the valve rod to rotate; wherein the valve body is fixed with a frame on the outer wall thereof, and a plurality of limit holes are arranged in the rotating direction of the handle; one end of the handle passes through the valve rod along the radial direction of the valve rod and is provided with a locating bump which is in the different limit holes during the rotation of the handle. The butterfly valve is simple in structure, convenient in operation to easily achieve the self-locking of the valve.
Description
Technical field
The utility model relates to a kind of valve, especially designs a kind of butterfly valve of being convenient to control the unlatching amplitude.
Background technique
Existing reed valve comprises valve body, valve rod, valve plate and handle.Valve plate is arranged in the runner of valve body by the valve rod that can rotate, and the upper and lower end of valve rod and valve body cooperation place are provided with seal ring.Handle is fixedlyed connected with valve rod, by handle with sleeve, opens or closes valve plate.
Existing reed valve structure dress is simple, use extensively, but since valve plate open and close the rotation that relies on handle fully, behind valve open, cannot lock valve.
Summary of the invention
The utility model provides a kind of butterfly valve, has solved the problem that existing butterfly valve can't limit the valve plate opening degree, simple in structure and convenient control.
A kind of butterfly valve of being convenient to control the unlatching amplitude, comprise valve plate in the valve body, valve body, with the fixedly connected valve rod of valve plate be connected the handle that is used to drive the valve rod rotation with valve rod one end, valve outer wall is fixed with support, the handle sense of rotation has some spacing holes in the support upper edge, described handle one end radially runs through valve rod along valve rod, the termination of this end of handle has positioning convex, and positioning convex was located in different spacing holes when handle rotated.
Described valve rod comprises a rotating shaft that is rotatably assorted with support, has a shoulder hole radially in rotating shaft, and the described handle that runs through valve rod is slidingly arranged in the shoulder hole, and the handling portion in the macropore is with a spring that makes positioning convex press to positioning hole.
Support upper edge handle sense of rotation has 4 spacing holes, 4 spacing holes, lay respectively at handle rotate 0 degree, when 23～27 degree, 63～67 and 90 are spent, the pairing position of positioning convex.
In order to realize the location of different opening degrees, can increase the quantity of spacing hole as required
Above-mentioned handle also is provided with handball away from an end of support.
The advantage of the utility model butterfly valve is: simple in structure, easy to operate, realized the self-locking of valve state easily.
Description of drawings
Below in conjunction with accompanying drawing butterfly valve of the present utility model is done following detailed description the in detail.
Fig. 1 is the structural representation of the utility model butterfly valve.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Embodiment
Butterfly valve structure schematic representation as shown in Figure 1, comprise valve plate in the valve body 1, valve body, with the fixedly connected valve rod 2 of valve plate be connected the handle 8 that is used to drive valve rod 2 rotations with valve rod 2 one ends.
Valve body 1 outer wall is fixed with support 4, and support 4 is a cylindrical body, and valve rod 2 is arranged on support 4 inside with one heart.
There is a rotating shaft 5 that is rotatably assorted with support 4 valve rod 2 upper ends.Rotating shaft 5 is fixedlyed connected with packing ring 11 by screw 10 with valve rod 2, and rotating shaft 5 also can be made of one with valve rod 4.
In rotating shaft 5, have a shoulder hole radially.Handle 8 one ends are slidingly arranged in the shoulder hole, and the handling portion in the shoulder hole macropore is with a spring 7.Spring 7 one ends prop up the termination of handle 8, and the other end props up aperture.
Be provided with a positioning convex 3 in the termination of handle 8, on support 4, have row's spacing hole along handle 8 sense of rotation.
Support 4 upper edge handles 8 sense of rotation have 4 spacing holes, and 4 spacing holes lay respectively at that handle rotates 0 degree, positioning convex 3 pairing positions when 25 degree, 65 and 90 are spent.
When handle 8 was in above-mentioned 4 angle states, positioning convex 3 can be inserted corresponding spacing hole, realized the fixing of handle 8.
When handle 8 rotated, spring 7 pushed the termination of handle 8 towards support 4, make positioning convex 3 be located in different spacing holes.When opening or closing valve, earlier handle 8 is pulled outward, spring 7 compressions, positioning convex 3 breaks away from behind the spacing holes handle with sleeve again.
Also be provided with the handball of being convenient to hold in the handle outer end, handball is made up of lobe in the handball 9 and the outer lobe 6 of handball.
Claims (5)
