Background technology
Elastic sluice valve with wedge-shaped sealing face is called elevating lever gate valve (being also Outside screw stem rising through handwheel type gate valve).Usually there is trapezoidal thread on elevating lever, lead to
The guide groove on the nut and valve body of valve tip is crossed, rotary motion is changed into moving along a straight line, that is, operation torque is changed into
Operate thrust.During Open valve, when flashboard hoisting depth is equal to the 1 of valve latus rectum：At 1 times, the passage of fluid is completely unimpeded, but
Operationally, this position can not monitor.In actual use, it is using the vertex of valve rod as mark, that is, opens motionless position,
As its fully open position.To consider that deadlock phenomenon occurs in temperature change, usually on vertex position is reached, then 1/2-1 is refunded
Circle, the position as standard-sized sheet valve.Therefore, the fully open position of valve, is determined by the position (i.e. stroke) of flashboard.
But traditional elastic sluice valve with wedge-shaped sealing face is in use there are some drawbacks, such as：
Traditional elastic sluice valve with wedge-shaped sealing face is directly provided with flashboard in threaded screw rod bottom, is sealed pipeline using flashboard
It is stifled, for preventing current, but due in pipeline hydraulic pressure pressure be easily bent in use compared with the flashboard of great tradition, lead
Cause ram seal effect to reduce, influence the actual use of gate valve.
