Hydraulic control a powerful personBe by advocate a powerful person and the needle entity a powerful person that hold outside its are become with the combination such as priority valve.

　　 Hydraulic control a powerful personIt is a series of multipurpose control and safety kind the floorboard of valve. Basically include:

1) remote control ball cock;

2 pressure-relief valve;

3 delay close type check valve;

A powerful person of 4 pressure release;

5 hold press a powerful person to wait a moment.

Their main characteristic is: Medium oneself pressure and operation of hydraulic pressure system are used on effect way, and can automata, movement accurate, function is reliable, control and safe effect have in can applying extensively at life production and conduit of system of fire control water supply.

But when hydraulic control a powerful person uses in the project, still put in certain error, be like the applicable condition of a powerful person, the design of a powerful person chooses a requirement, installation point, for this, the article drafts with CECS standard " application of hydraulic control a powerful person designs regulations " (send go over a manuscript or draft) for the foundation, the experience that combines oneself will elaborate afore-mentioned problems of all respects.

　　 A powerful person of 1, hydraulic controlThe design chooses a point

The hydraulic control a powerful person that uses in 1 project type is course manufactory certificate of proof, all sorts of labels are all ready, technical data accords with the product of the requirement.

2 basises functional requirement, choose valve sort, carry standard of medium, temperature, building and owner to want to ask to wait according to conduit again, the material of the body of a powerful person of certain valve and sealed place is qualitative. Material of commonly used body of a powerful person has cast-iron, copper iron, copper, plastic etc. Commonly used sealing surface and liner material have copper alloy, plastic, steel, hard alloy, balata to wait. Material of body of a powerful person should match with conduit data phase.

The nominal pressure of 3 valve has 0.6, 1, 1.6, 2.5 wait for different level with 4.0MPa, the medium that conduit carries, its actuating pressure should be less than the nominal pressure value of valve.
