The loam cake of described leakproof valve has Upstream Interface on (101).
The small end of the housing of described valve (102) has downstream interface.
Working procedure of the present utility model is as follows:
Described leakproof valve (1) is installed between the pipeline (2) and monitoring pipeline leakage whether sensor (3) of carrying liquid or gas.Pipeline just often valve (103) under the pressure effect of the liquid of the effect of elastic element and upstream and downstream jointing or gas, transfixion; When sensor breaks down, when liquid in the pipeline or gas took place to leak, valve (103) moved to housing (102) small end vertically, and the male cone (strobilus masculinus) of valve (103) closely contacts with the inner conical surface of housing (102), prevents the further leakage of liquid or gas.
Advantage of the present utility model:
When can be implemented in sensor and breaking down, the leakproof valve energy is closed voluntarily, prevents the further loss of liquid in the pipeline or gas, has avoided the waste of medium and the pollution of environment, this valve is a mechanical structure, reliable operation, compact structure, volume is little, in light weight, the manufacturing cost is low, easy for installation, safeguard simple, can adapt to various environment, long service life can be widely used in the pipeline monitoring.
