Description
Technical field
The utility model relates to the technical field of valve body power switch, particularly a kind of technical field to fixture block rotation inhibiting valve body control gear.
Background technique
Along with the fast development of industry, commercial scale is increasing, need in industrial processes to use various pipeline, cut-off in some pipeline is little to human injury, so danger is less, can be satisfied the demands by manual operation, but for the operation of the larger and a large amount of valve body of danger, pass through manual hand manipulation, first be that efficiency is low, labor intensity is large, secondly certain injury is had to the health of people, be used on the switch of valve body by pneumatic or the valve body controlled that surges at present, but navigation designing is not had to fixture block, often due to transport, installation or other reason make to rotate fixture block, thus band ovable valve stem reverses, affect the precision of valve electropneumatic positioner.
Summary of the invention
The purpose of this utility model solves the problems of the prior art exactly, propose a kind of to fixture block rotation inhibiting valve body control gear, the motion performing bar can be realized by liquid or gas push power film, can prevent from rotating fixture block by guide plate simultaneously, avoid band ovable valve stem to reverse, affect the precision of valve electropneumatic positioner.
For achieving the above object, the utility model proposes a kind of to fixture block rotation inhibiting valve body control gear, comprise membrane cover, power film, pad watt, return spring, drive link, support, to fixture block and execution bar, power film is provided with in described membrane cover, described power film top is provided with pad watt, some return springs are provided with in described pad watt, pad watt is fixedly connected with drive link by nut, described drive link is fixedly connected with fixture block by two with execution bar, membrane cover bottom is provided with support, described support is provided with guide plate, described guide plate is arranged between fixture block.
As preferably, the membrane cover of described power film both sides is respectively arranged with pressure medium and imports and exports.
As preferably, describedly on fixture block, bolt is installed, drive link with perform bar and clamped by fixture block by bolt.
As preferably, be provided with 4 return springs in described pad watt, described return spring one end contacts with pad watt, and the return spring the other end contacts with membrane cover.
As preferably, described drive link, through power film, drive link is provided with backing plate, is provided with power film between described backing plate and pad watt.
The beneficial effects of the utility model: the utility model by by membrane cover, power film, pad watt, return spring, drive link, support, to fixture block and perform bar be applied on valve body power switch, the motion performing bar can be realized by liquid or gas push power film, can prevent from rotating fixture block by guide plate simultaneously, avoid band ovable valve stem to reverse, affect the precision of valve electropneumatic positioner.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
