Description
Technical field
The present invention relates to a kind of integrated cut-off clack boxes of low noise, belong to shut-off valve technical field.
Background technology
Salt water cooling system on naval vessel is usually by pump group, the pipeline being connect with pump group and the shut-off valve on pipeline
It constitutes, the refrigerated sea water of pump group outlet supplies water respectively to stem after manifold and ship stern supplies water, although shut-off valve can play shunting
And antihypertensive effect, but flow cannot be allocated.Therefore the water matching of existing stem, stern cooling user is to pass through pipeline
And T tube and shut-off valve are realized, also need to use firm discharge regulating valve, Cai Nengman to the fixed user of individual water demands
Foot subset regulatory demand.Since pump group is typically that control stem is adjusted in water main's flow and ship stern supplies by controlling
Water, under cooling equipment difference operating mode, when the seawater flow demand of stem and ship stern changes, be by manual rotation respectively
Handwheel on shut-off valve carries out simple flow adjusting control, and the flow control response time is long and also inaccurate, and increases operation
The workload of personnel.Secondly, pump group outlet is through three-way pipe and refrigerated sea water is led to stem to two outlet connecting pipes and stern is cold, and
Shut-off valve is separately installed in each connecting tube, but shut-off valve does not have assignment of traffic function, loosely organized, volume is relatively large,
It cannot be mounted on the place of narrow space, also increase the weight weight of cooling system, and can not achieve miniaturization.Moreover at present
This cooling system requires the seawater flow in pump group exit very big, at the distributing T-pipe that seawater passes through pipeline, will produce non-
Normal heavy turbulence phenomenon, therefore pipeline noise is larger when seawater being caused to flow.
