Abstract
The utility model discloses a novel pressure-reducing valve with a simple structure, a long service life and a favorable sealing performance. The novel pressure-reducing valve is characterized by comprising an adjusting screw, a spring, a valve seat, a piston, a valve body, a switch ring, a valve rod and a seal. According to the novel pressure-reducing valve, the seal is arranged at the lower part of the piston; the piston is embedded into the seal; and a silk screen interlayer is arranged inside the seal.
Description
Technical field
The utility model relates to a kind of valve field, particularly a kind of novel reduction valve.
Background technique
Thereby reduction valve is to change by being stressed to move up and down to drive valve core movement in the prior art, and valve core movement makes the medium inlet open and close dimensional changes, plays decompression by throttling, transports merit up and down but diaphragm moves in circles, and causes the diaphragm fatigue ruption easily.Thereby reduction valve was lost efficacy.
Summary of the invention
A kind of novel reduction valve, comprise: adjusting screw rod 1, spring 2, valve seat 3, piston 4, valve body 5, switch ring 6, valve rod 7, sealing 8, described a kind of novel reduction valve is that piston 6 bottoms are provided with sealing 8, and sealing 8 is in piston 6 is embedded in, and seals 8 inside and is provided with the silk screen interlayer.
Beneficial effect of the present invention: simple in structure, product is durable in use, makes seal ring can bear bigger pressure because sealing has added the silk netting interlayer, is not easy to damage.
Description of drawings.

Embodiment
Describe the present invention below in conjunction with accompanying drawing
Described a kind of novel reduction valve is that piston 6 bottoms are provided with sealing 8, sealing 8 is in piston 6 is embedded in, seal 8 inside and be provided with the silk screen interlayer, adjusting screw rod 1 turns clockwise, by spring 2 pressure valve rod 3 is moved upward, valve rod moves upward and drives piston 4 and move upward, thereby valve body 5 medium inlet sizes are increased, pressure also increases, and moving then counterclockwise, pressure reduces.
