Description
Technical field
The present invention relates to the pressure-reduced and-regulated devices more particularly to a kind of vertical pressure reducing valve in a kind of pipeline.
Background technique
Pressure reducing valve is the outlet pressure that a certain needs are reduced to by adjusting inlet pressure, and relies on the energy of medium itself,
Outlet pressure is set to automatically keep stable valve.The pressure reducing valve of the prior art is not very due to the sealing performance of internal structure piston
Good, gas is leaked to the other side of piston from low pressure chamber, causes pressure reducing valve decompression performance unstable, plays less than optimum efficiency.
In conclusion how to provide a kind of pressure reducing valve, to improve its security reliability, and then meet the requirements stringenter high temperature and pressure or
Requirement of the superhigh-pressure high-temp operating condition to pressure reducing valve security reliability, is a problem to be solved by those skilled in the art.
Summary of the invention
The present invention provides a kind of simple structure, applied widely, safety and stability, automatic control in order to solve problem above
It makes, operating cost is low, vertical pressure reducing valve with long service life.
The technical scheme is that the pressure reducing valve include pedestal, pedestal gasket, valve body, main spring, valve seat,
Flap, flap gasket, diaphragm, lower spring cup, adjustment spring, upper spring seat, upper cover, adjusting nut and shield, it is described
Pedestal is arranged in pressure reducing valve bottom end, and the valve body is connected on pedestal, and engaging portion is provided with pedestal gasket, the valve seat
Setting is arranged between valve body and valve seat in valve body top, the main spring, and the flap is arranged in valve seat, described
Diaphragm is set on the outside of flap, and flap gasket is arranged in engaging portion, and the top of valve seat, the adjusting bullet is arranged in the upper cover
Spring is arranged in upper cover, and both ends are respectively set upper spring seat and lower spring cup, and the shield setting is described on upper cover top
Adjusting nut be arranged in shield.
The configuration of the present invention is simple, applied widely, safety and stability, automatic control, operating cost is low, long service life.
Detailed description of the invention
