Description
Technical field
Technical field of fire control is the utility model is related to, is specifically a kind of Novel firefighting valve.
Background technology
Fire valve is widely applied to each occasion during we live, for taking precautions against the generation of fire incident.Fire-fighting
It fire occurs is that can just enable that valve, which is, is typically all permanent in the state closed, current fire valve is in order to occur fire
Calamity is can quickly to open and the break-make of water is controlled using shut-off valve, and the pressure of such water is concentrated at the sealing of spool will
It is especially big, especially for a long time in the case of；Fire rescue is seized every minute and second, and when being again turned on when fire occurs, is concentrated
Valve is again turned in the pressure at seal spool just relatively painstaking more difficult, influence the rescue of fire；Existing fire valve
Gasket is mostly fixed with the spool on valve rod, so during fire valve opens and closes, make valve rod rotate and with movable valve plug and
Gasket rotates, and reaches the keying of fire valve according to this, but during keying, produced between the rotation meeting of gasket and valve body
In the case that raw larger friction, especially fire valve water pressure unused for a long time are big, the permanent feelings of gasket at next sealing
The situation of leakage can be produced under condition because of the pressure of water, so as to cause to damage to fire valve.
