Background technique
At present, the gate valve of institute's main flow on market, stop valve and other valve rod class valve be all to drive flap seat (flashboard) to move by valve rod by indicating arm, realizes that valve moves up and down, more fixedly prevent transfer problem by nut.But this structure has following shortcoming: 1, valve rod coordinates with indicating arm, screw thread is if any wearing and tearing meeting impact position stroke inaccuracy, and the destruction to valve rod, affects valve rod intensity.2, indicating arm is clear not to the display mode of valve, clearly can not show the upper and lower travel position of valve, and unsuitable clamping dismounting, processing cost is high.
Model utility content
For the problems referred to above, the utility model aims to provide a kind of detachable instruction folder stroke switching path display unit of valve and the anti-rotation device preventing valve rod from rotating combined and indicates and anti-rotation Difunctional valve.
For realizing this technical purpose, scheme of the present utility model is:
A kind of detachable instruction folder stroke instruction and anti-rotation Difunctional valve, comprise valve body, valve seat, flap, valve rod, packing ring, valve gap, upper seal support cover, spacer ring, seal ring, circle pin, feeding port, filler pressing sleeve, hold-down grid, bolt, nut, screw A, operated gear device, instruction folder, screw B, valve gap bolt, bonnet nut, spring and flap seat, described valve body is fixed on valve seat, described flap is arranged on flap seat by screw B, and be close to the side of valve seat, described valve rod is fixedly connected with valve gap with bonnet nut by valve gap bolt spiral shell, described packing ring is arranged on the connecting part of valve rod and valve gap, described upper seal support is set on the inside of valve gap, and upper end is provided with spacer ring, described seal ring is fixed between feeding port and spacer ring, and described circle pin one end is connected to the lower end of bolt, and the other end is arranged on valve gap, described filler pressing sleeve is arranged on the upper end of feeding port, described hold-down grid is fastened on valve gap top by screw bolt and nut, and described operated gear device is fixed on the top of valve rod by screw A, and described instruction folder is locked on valve rod by screw A, described spring contacts with flap, and is arranged on the inside of valve body.
As preferably, described valve rod and instruction adopt circular bayonet fittings between pressing from both sides, and are locked by screw A.
As preferably, one end of described instruction folder is embedded in the instruction groove of valve gap.
The utility model increases an instruction folder between valve rod and valve gap, instruction is pressed from both sides do not rotate relative to valve gap, instruction folder is embedded in the instruction groove of valve gap, restriction instruction folder produces relative rotation with valve gap, valve rod and instruction adopt circular bayonet fittings between pressing from both sides, instruction accompanies the endoporus and thickness (having step) tolerance that coordinate with valve rod, fixes, then locked with screw with valve rod.The switching path display unit of valve and the anti-rotation device preventing valve rod from rotating are combined, effectively control the precision of position stroke, improve the practicability of valve, thus reach the precision of position stroke and improve valve stability, extend the working life of valve, reduce processing cost, be convenient to maintenance, greatly saved processing cost.
