Description
Technical field
This utility model belongs to valve manufacture field, and in particular to gate valve is manufactured, more particularly to a kind of safe 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 it is different, usually 5 °, when medium temperature is not high for 2 ° 52 '.Improve its technique
Property, the deviation that sealing surface angle is produced in process is made up, 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 by the close of flashboard
Front cover presses to the valve seat of opposite side to ensure the sealing of sealing surface, here it is self sealss.Most of gate valve is to adopt forced seal
, i.e., valve closing when, 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 and valve body of valve tip, rotary motion is changed into into linear motion, 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 it is logical
Road is completely unimpeded, but operationally, this position cannot monitor.When actually used, it is using the summit of valve rod as mark, i.e.,
Motionless position is opened, as its fully open position.To consider that deadlock phenomenon occurs in temperature change, generally vertex position is being reached
On, then 1/2-1 circles are refunded, 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 valve are located on flashboard, and hand wheel rotating band ovable valve stem is rotated, and is lifted flashboard, this valve
Door is called swingle gate valve or is inside screw nonrising stem type gate valve.
In prior art, gate valve using very laborious, use it is highly difficult, sometimes gate valve be used gate valve hand wheel long due to
It is too small, more bad unlatching.
Utility model content
For above-mentioned deficiency of the prior art, this utility model provides a kind of safe gate valve.
A kind of safe gate valve, it is characterised in that include：Gate valve main body, gate valve hand wheel, gate valve rotating shaft, gate valve rotating shaft tooth, lock
Bonnet, gate valve installing hole, gate valve plate and gate valve connecting rod, the gate valve hand wheel, gate valve rotating shaft, gate valve plate and gate valve connecting rod phase
Mutually it is welded, in the gate valve main body, is provided with multiple gate valve installing holes, the gate valve cap is arranged on the top of gate valve main body,
A circle sealing shroud is provided with the outside of the gate valve cap, the gate valve rotating shaft and gate valve connecting rod are arranged on lock bonnet interior, institute
State gate valve rotating shaft to be meshed with gate valve rotating shaft tooth, the gate valve plate is arranged on gate valve body interior.
The gate valve hand wheel is circle, and the radius of the gate valve hand wheel is 30-50mm.
The gate valve installing hole is buckle-type installing hole.
The gate valve plate is basalt fibre plate.
The gate valve connecting rod is Aluminum alloy round bar.
The sealing shroud is one layer of rubber sealant.
