Abstract
The utility model provides a butterfly valve, which comprises a valve body, a butterfly plate, a valve rod, a flange fluted disc and a handle, wherein the valve body is provided with a shaft hole; the lower end of the valve rod penetrates through the shaft hole and is fixedly connected with the butterfly plate; the upper end of the valve rod penetrates through the flange fluted disc and is fixedly connected with the handle; and the butterfly valve also comprises a valve rod positioning device arranged between the flange fluted disc and the handle. The device is simple in structure, convenient to use, low in cost, safe and reliable; the opening or closing position of the butterfly valve can be fixed, and the positioning effect is good; and the butterfly valve can be operated by the handle or a screw spanner, and can control the flow of a passing medium.
Description
[technical field]
The utility model relates to a kind of butterfly valve, relates in particular to a kind of a kind of butterfly valve that has the valve rod positioning device.
[background technique]
Butterfly valve is Flap valve again, be a kind of modulating valve simple in structure, also can be used for the switch control of low pressure pipeline medium simultaneously, butterfly valve refers to that closure member (flap or butterfly plate) is disk, center on a kind of valve that valve shaft rotates to reach open and close, main rising cut off and throttling action on pipeline.Butterfly valve is that it does not allow the medium small flow to flow through in butterfly valve for a long time with a kind of valve of opening, close and regulate the fluid passage about closure member reciprocating rotating 90 degree.Moreover, the location was fixed in the tooth plate by positioning work piece on the handle when butterfly valve routine was opened or closed, because handle positioning work piece and tooth plate centre distance sum of errors handle cause butterfly valve open and close location to be forbidden in the skew of valve rod axial position, can't fix.
[model utility content]
The purpose of this utility model is to provide a kind of butterfly valve, so that fixedly butterfly valve is opened or closed position, and can control the size by rate-of flow.
For reaching aforementioned purpose, a kind of butterfly valve, comprise valve body, butterfly plate, valve rod, flange fluted disc and handle, described valve body is provided with axis hole, described valve rod lower end passes described axis hole and described butterfly plate is fixedly connected, described valve rod upper end passes the flange fluted disc and described handle is fixedly connected, and also comprises the valve rod positioning device, and described valve rod positioning device is arranged between flange fluted disc and the handle.
According to an embodiment of the present utility model, described valve rod positioning device comprises positioning plate, positioning hole and holding down bolt, described positioning plate is passed in described valve rod upper end, described positioning plate is arranged between flange fluted disc and the handle, be drilled with positioning hole on the described positioning plate, described positioning plate rotates together with valve rod, when butterfly valve opens or cuts out, hole on the described positioning hole alignment flange fluted disc, and be connected and fixed by described holding down bolt.
According to an embodiment of the present utility model, described positioning hole is a plurality of.
The utility model beneficial effect: compared with prior art, a kind of butterfly valve, comprise valve body, butterfly plate, valve rod, flange fluted disc and handle, described valve body is provided with axis hole, described valve rod lower end passes described axis hole and described butterfly plate is fixedly connected, described valve rod upper end passes the flange fluted disc and described handle is fixedly connected, and it is characterized in that: also comprise the valve rod positioning device, described valve rod positioning device is arranged between flange fluted disc and the handle.This device has simple in structure, and is easy to use, with low cost, safe and reliable, and fixedly butterfly valve is opened or closed position, good positioning effect, and available handle or monkey spanner all can be operated, and can control the size by rate-of flow.
