Description
Technical field
The utility model belongs to valve manufacture field and in particular to gate valve manufacture, more particularly, to a kind of corrosion-resistant gate valve.
Background technology
Gate valve（gate valve）It is an opening and closing element flashboard, the direction of motion of flashboard is perpendicular with flow direction, gate valve
Standard-sized sheet and fully closed can only be made, uncomfortable door parameter and different, improve its manufacturability, make up what sealing surface angle produced in process
Deviation, this flashboard is called flexible disc.
When gate valve is closed, sealing surface can rely only on pressure medium to seal, that is, rely only on pressure medium flashboard is close
Front cover presses to the sealing to ensure sealing surface of the valve seat of opposite side, here it is self sealss.Most of gate valve is to adopt forced seal
, that is, during valve closing, flashboard is pressed to valve seat by external force to be relied on by force, to ensure the sealing of sealing surface.
Motion mode：The flashboard of gate valve is for linear motion with valve rod, is also Outside screw stem rising through handwheel type gate valve.Generally on elevating lever
There is trapezoidal thread, by the guide groove on the nut of valve tip and valve body, rotary motion is changed into moving along a straight line, that is, will
Operation torque is changed into operating thrust.During Open valve, when flashboard hoisting depth is equal to the 1 of valve latus rectum：When 1 times, fluid logical
Road is completely unimpeded, but operationally, this position cannot monitor.When actually used, it is using the summit of valve rod as mark, that is,
Open motionless position, as its fully open position.For consideration temperature change, deadlock phenomenon occurs, generally reaching vertex position
On, then refund 1/2-1 circle, as the position of standard-sized sheet valve.Therefore, the fully open position of valve, by the position of flashboard（At once
Journey ＞ is determining.Some valve rod nut for gate valves are located on flashboard, and hand wheel rotating band ovable valve stem rotates, and so that flashboard is lifted, this valve
Door is called swingle gate valve or is inside screw nonrising stem type gate valve.
