Description

Valve shaft concentricity adjusting device of horizontal poppet valve Technical Field The utility model relates to the technical field of horizontal type lifting valves, in particular to a valve shaft concentricity adjusting device of a horizontal type lifting valve. Background The concentricity of the valve shaft of the horizontal poppet valve directly relates to whether the opening and closing actions of the valve are smooth and accurate. If the concentricity of the valve shaft is deviated, the valve can not be completely opened or closed, so that the on-off control of the fluid is influenced, and the normal operation of the whole system is further influenced. But current valve shaft can not conveniently adjust, leads to equipment machining precision to require highly. For this reason, we propose a valve shaft concentricity adjusting device of a horizontal poppet valve to solve the problem. Disclosure of utility model The utility model aims to provide a valve shaft concentricity adjusting device of a horizontal type lifting valve, which solves the problems in the background technology. In order to achieve the purpose, the utility model provides the following technical scheme that the valve shaft concentricity adjusting device of the horizontal type lifting valve comprises: a valve plate; The valve shaft, the outer wall and the valve plate are arranged; The poppet valve adjusting fixing plate and the poppet valve adjusting plate are arranged at the outer position of the valve shaft; The fixed bearing and the ball bearing are both arranged with the poppet valve adjusting plate and are used for fixing the valve shaft; and the adjusting bolt is connected with the lifting valve adjusting and fixing plate. Preferably, an air cylinder is fixedly arranged at the end part of the valve shaft. Preferably, the number of the ball bearings is two, and the two ball bearings are symmetrically distributed at two sides of the fixed bearing. Preferably, the number of the adjusting bolts is two, and the two adjusting bolts are symmetrically distributed on the central line of the poppet valve adjusting fixing plate. The utility model provides a valve shaft concentricity adjusting device of a horizontal type lifting valve. The valve shaft concentricity adjusting device of the horizontal type poppet valve has the following beneficial effects: According to the valve shaft concentricity adjusting device of the horizontal type lifting valve, the two ball bearings and the one fixed bearing are arranged to position the valve shaft fixing column, so that the heights of the two ends of the valve shaft can be flexibly adjusted, and the requirement of equipment on machining precision is effectively reduced.
