Abstract
The utility model discloses a butterfly valve, which comprises a valve body, a valve rod, a butterfly board and a handle, wherein the handle is fixedly connected with the top portion of the valve rod, the lower portion of the valve rod passes through the valve body to be fixedly connected with the butterfly board, a contact position of the valve rod and the valve body is sealed and connected through stopping, and a connecting piece which is used to fix the valve body is arranged on one side of the valve body. The butterfly valve enables a valve to be more steady during the mounting or using process by adding the connecting pieces on the valve body, simultaneously prevents the handle from rotating in excess to damage the butterfly board and the valve body by adding a positioning strip for blocking the handle on the top portion of the valve body, and prolongs service life of the valve.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of butterfly valve.
Background technique
Butterfly valve is that it is simple in structure with a kind of valve of opening, close and regulate the fluid passage about disc type open-shut device reciprocating rotating 90 degree, and volume is little, in light weight, material consumption is economized, and installation dimension is little, driving moment is little, simple to operate, rapidly, but also can have good flow regulating function simultaneously and close sealing characteristics, but in installation process, itself does not have fixed block valve body, needs especially to fix by external component when fixed valve body, so be badly in need of now addressing the above problem.
Summary of the invention
At the problems referred to above, the purpose of this utility model proposes a kind of butterfly valve with fixed block.
A kind of butterfly valve, comprise: valve body, valve rod, dish plate and handle, described handle is fixedlyed connected with the top of valve rod, the bottom of described valve rod is passed valve body and is fixedlyed connected with the dish plate, described valve rod and valve body contact position are tightly connected by stuffing, and a side of described valve body is provided with the link for fixed valve body.
Described valve body top is provided with the positioning strip for the backstop handle.
A kind of butterfly valve of the utility model is by setting up link at valve body, make valve from more stable in installation or using process, set up the positioning strip for the backstop handle simultaneously at the valve body top, prevent that the handle rotation is excessive, damage dish plate and valve body, increased the working life of valve.
Description of drawings
Fig. 1 is a kind of butterfly valve side-looking of the utility model structural representation.
Fig. 2 is the opposite side TV structure schematic representation of a kind of butterfly valve of the utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As depicted in figs. 1 and 2, structural representation for a kind of butterfly valve of the utility model, comprise: valve body 1, valve rod 2, dish plate 3 and handle 4, described handle 4 is fixedlyed connected with the top of valve rod 2, described valve body 1 top is provided with the positioning strip 5 for backstop handle 4, the bottom of described valve rod 2 is passed valve body 1 and is fixedlyed connected with dish plate 3, and described valve rod 2 is tightly connected by stuffing with valve body 1 contact position.
One side of described valve body 1 is provided with the link 6 for fixed valve body.
When a kind of butterfly valve of the utility model is installed, at first by link 6 valve body 1 is fixed on metope or other fixed blocks, then with valve body 1 two ends and pipeline connection, the folding direction of regulating handle 4 and valve rod 2 gets final product complete operation.
The utility model only carries out illustrative with above-described embodiment; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
