Watery diarrhea wastes duration, does not has the displacement simulating a shower nozzle that system carries out the problem of linkage test function, this utility model
Thering is provided a kind of combined water-drainage valve, rated operating pressure is 1.6MPa；This utility model devises two passages of built-in size
Valve body, passage aisle simulation one shower nozzle displacement carry out system interlink test, big passage possesses the draining bore of DN50,
Wet alarm valve, dry type alarm valve are with a wide range of applications, meet boats and ships, tunnel small space in use want
Ask.
This utility model is achieved through the following technical solutions:
Combined water-drainage valve is by O, valve body, locking nut, small sealing ring, little valve gap, small screw, small handwheel, little valve
Dish, large sealing packing ring, big valve disc, big valve gap, big handwheel, big screw rod, pad form；Water inlet is equipped with O, locking nut, valve
Equipped with little valve gap on the upside of body, being installed with small screw in little valve gap, equipped with small handwheel above small screw, lower section is equipped with little valve disc, little
Sealing ring；Being installed with big valve gap on the right side of valve body, equipped with big screw rod in big valve gap, equipped with big handwheel on the right side of big screw rod, big screw rod is left
Side is equipped with big valve disc, large sealing packing ring；Valve closing seals at ordinary times；During test, small handwheel of outwarding winding, simulate a shower nozzle draining；Dimension
When repairing, big handwheel of outwarding winding, system pipe network draining.
The beneficial effects of the utility model are: devise the valve body of double passages of built-in size, by motion test with fast
Speed two valve optimizations of draining are designed as a valve, decrease pipe fitting, have saved space；Solve current alerts valve draining to delay
Slow problem, it is achieved that the displacement of one shower nozzle of simulation carries out the function of linkage test to system.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is profile of the present utility model.
Fig. 2 is the valve body profile in this utility model.
Fig. 3 is the big valve disc profile in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by detailed description of the invention:
Combined water-drainage valve is by: O (1), valve body (2), locking nut (3), small sealing ring (4), little valve gap (5), little
