Abstract
The utility model relates to an aperture indicator of an open rod valve/a gate, which is provided with a cylinder-shaped and nonferromagnetic material protective cover. One end of the protective cover is closed, and the other end is provided with a mounting hole. An inner magnet block is arranged in the cylinder-shaped protective cover. An outer ferromagnetic block is arranged outside the protective cover. The outer ferromagnetic block which is at a distance from the wall of the nonferromagnetic material cylinder-shaped protective cover attracts the inner magnet block arranged in the protective cover. When the utility model is used, the inner magnet of the utility model is connected with the outer end of a valve/a gate rod of the open rod valve/ the gate in a positioning mode, and the protective cover is arranged on a headstock gear or an opening and closing driving device of the open rod valve/the gate. The valve/the gate rod are covered in the protective cover, which causes the outer ferromagnetic block which is at a distance from the wall of the protective cover to be attracted to the outer wall of the protective cover by the inner magnet block. When the valve/ the gate is opened or closed, the valve/the gate rod lifts and drops so as to drive the magnet block to lift and drop, and the inner magnet block drives the outer ferromagnetic block arranged on the outer wall of the protective cover to lift and drop. The aperture of the valve/ the gate can be easy to judge according to the position of the outer ferromagnetic block which is lifted and dropped on the protective cover.
Description
Technical field
The utility model relates to a kind of rising stem valve/gatage indicator.
Background technique
Valve/the flashboard of rising stem valve/gate is connected with valve/restrictor bar, and valve/restrictor bar is a screw rod, and when valve/lock was opened, it is external that valve/restrictor bar stretches out valve/lock, and the length of stretching out by inspecting valve/restrictor bar can be judged the aperture of valve/lock.Valve/lock the screw rod that stretches out for protection is not corroded by external environment; in the prior art; on the valve/restrictor bar of valve/gate, be covered with the cylindrical shape protective housing; the upper end closed of cylindrical shape protective housing; lower ending opening; there is mounting hole the protective housing lower end, and protective housing is installed in the hoist on valve/lock body by mounting hole or opens and closes on the transmission device, and valve/restrictor bar is covered in the protective housing.The protective housing of this rising stem valve/gate is after on valve/restrictor bar cover.When valve/gate opening, can not observe the length that valve/restrictor bar stretches out, thereby be difficult to judge the aperture of valve/gate.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of rising stem valve/gatage indicator that valve/restrictor bar is had protective action.
The utility model is realized with the following method.
Rising stem valve/gatage indicator has the cylindrical shape protective housing of the end sealing identical with above-mentioned prior art, the other end of cylindrical shape protective housing has mounting hole, the cylindrical shape protective housing is made with non-ferromagnetic body material, the internal magnet piece is arranged, the outer ferromagnet piece that protective housing has the cylindrical shape enclosure wall made across non-ferromagnetic body material and the internal magnet piece in the protective housing to attract each other in the cylindrical shape protective housing outward.The internal magnet piece is the ferromagnet piece outside the cylindrical shape enclosure wall that non-ferromagnetic body material is made attracts, and outer ferromagnet piece is attracted on the outer wall of protective housing by the internal magnet piece.
During use, internal magnet piece of the present utility model location is connected in the outer end of the valve/restrictor bar of rising stem valve/gate, allow a magnetic pole of internal magnet piece press close to the inner tube wall of protective housing, the cylindrical shape protective housing is identical with protective housing in the prior art, be installed on the hoist or keying transmission device of rising stem valve/lock, valve/restrictor bar is covered in the protective housing, allow outer ferromagnet piece across cylindrical shape enclosure wall that non-ferromagnetic body material is made is attracted outer wall at protective housing by the internal magnet piece on.During valve/gate opening/closing, the valve of valve/gate/restrictor bar lifting drives the internal magnet piece lifting of valve/restrictor bar outer end, and interior magnetic patch lifting drives the outer ferromagnet piece lifting that is attracted by interior magnetic patch on the protective housing outer wall.
When the utility model opened and closed, the magnet piece that is fixed on valve/restrictor bar outer end can drive the outer outer ferromagnet piece lifting of non-ferromagnetic body protective housing, from the position of outer ferromagnet piece lifting on protective housing, can be easy to judge the aperture of valve/gate.
Below in conjunction with accompanying drawing, the utility model is further described.
