Abstract
The invention provides a butterfly valve, which comprises a valve body, a butterfly plate, a valve rod, a flange fluted disc and a handle, wherein a shaft hole is formed in the valve body; 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; the butterfly valve further comprises a valve rod positioning device which is arranged between the flange fluted disc and the handle. The butterfly valve is simple in structure, convenient to use, low in cost, safe and reliable; moreover, the opening position or the closing position of the butter fly valve can be fixed, so that the positioning effect is good, and the butterfly valve can be operated by the handle or a movable wrench and can be used for controlling the size of the medium penetrating flow rate.
Description
[technical field]
The present invention relates to a kind of butterfly valve, relate 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 is meant that closure member (flap or butterfly plate) is a disk, rotate a kind of valve that reaches open and close around valve shaft, 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 about closure member reciprocating rotating 90 degree, close with the regulated fluid passage.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.
[summary of the invention]
The object of the present invention is to provide a kind of butterfly valve,, and can control size by rate-of flow so that fixedly butterfly valve is opened or closed position.
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 one embodiment of present invention, 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 one embodiment of present invention, described positioning hole is a plurality of.
Beneficial effect of the present invention: 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.
