A vertical pipeline anti- deflection stop valve

Abstract

The utility model discloses a perpendicular pipeline anti -migration's stop valve, including the valve body, the upper surface swing joint of valve body has the bonnet, the connecting place of valve body and bonnet outer surface all are screwed the first bolt, the lower surface fixed connection of bonnet has the first sealing washer. This perpendicular pipeline anti -migration's stop valve, through the setting of bonnet, adjusting lever, valve core, connecting rod and transparent box, the movement of adjusting lever is oriented and is limited by bonnet, prevents the deviation of adjusting lever in the movement process, ensures the centring of valve core and valve body, when adjusting lever moves up and down, connecting rod moves up and down in the inside of transparent box through the connecting plate, drives the pointer to move, and the scale line is used in cooperation, thereby directly shows the position of valve core in the valve body, can in the condition without disassembling stop valve, real -time understanding valve core's position state, simple structure, and the cost is lower, does not need additional power or complex control circuit.
