Description
Technical field
This utility model is related to valve field, more particularly, to a kind of pneumatic control combinaing valve body mechanism.
Background technology
China is greatly developing Chemical Industry, and the deslagging in gasification furnace, dust removing system operating mode are non-in the industry
Often severe, not only temperature height (reaching 1000 DEG C in short-term), pressure reduction are high for this system, and medium is solid particle or powder state shape, to valve
The performance requirement of door is very high it is desirable to valve has the features such as wear-resisting, corrosion-resistant, high temperature high voltage resistant, long service life.Exist at present
Generally it is installed together using two hard sealing o type ball valves under this operating mode, be divided into import and export side two valve, to ensure deslagging row
Ash system overall operation.But this kind of combination valve has the following disadvantages: 1, because the medium of ash discharge lock hopper exclusion is high-temperature coal
So that valve is in running, ground-slag state medium can be deposited in the valve pocket of ball valve, thus causing valve element and Jie for slag or coal dust
Matter rubs, and scratch sphere causes valve leak, under high pressure differential, valve internals are washed bad soon.And, ball valve
Due to its own architectural characteristic so that medium is easily piled up in valve body cavity body, block valve insertion, thus causing valve torque to increase
Greatly, the phenomenon such as spheroid clamping stagnation, not in place, the damage sealing surface of valve switch.Under high-pressure situations, when valve fits badly, pipeline
Medium can form Choking phenomenon, seriously washes away bad valve.In the case, affected by cavity inner product ash between two valve elements on the contrary,
Greatly reduce the service life of two valves, thus causing heavy economic lossess.2, the execution step of this kind of combination valve is very tight
Lattice, during following closing valve, need first to close a v type ball valve, convection cell is dammed, after inside cavity flows out
Close the 2nd o type ball valve；If first closing the 2nd o type ball valve, then inside runner, cut-off is stuck by causing inside entrance valve pocket；
