Description
Technical field
The utility model relates to valve field, relates in particular to a kind of direct acting pressure.
Background technique
Reduction valve is by regulating, inlet pressure being reduced to the outlet pressure of a certain needs, and rely on the energy of medium itself, makes outlet pressure automatically keep stable valve.From hydromechanical viewpoint, reduction valve is a throttle element that local resistance can change, and by changing orifice size, the kinetic energy of flow velocity and fluid is changed, and causes the different pressure losses, thereby reaches the object of decompression.Then rely on the adjusting of controlling with regulating system, the fluctuation of downstream pressure and spring force are balanced each other, make downstream pressure keep constant in certain margin of error.Along with the market demand of reduction valve is increasing, the kind of reduction valve is also more and more, and the most structure of these reduction valve more complicated is all not easy to operate.Therefore, need a kind of new technological scheme to address the above problem.
