Abstract
The utility model relates to a high sealing low noise one-way load reducing valve which is characterized in that one side of a close steel ball 8 is provided with a load reducing pilot valve which is provided with a piston 14 and a spring 16, and the left side of the piston 14 is communicated with a load reducing wind pipe 12. The operation of the steel ball 8 is controlled by utilizing the pressure of the load reducing wind pipe, and a load reducing port is opened. The high sealing low noise one-way load reducing valve has the advantages of good sealing property, low noise and flexible and reliability action, and a load reducing exhaust passage is spacious.
Description
The utility model relates to a kind of high airtight low noise non-return easing valve that is used for air compressor.
Using the easing valve on air compressor at present, is to adopt the plunger form spring sealed, after pressure reaches a certain value, back down the plunger off-load, this kind structure deficiency is a poor sensitivity, and the exhaust glouglou is big during off-loading, the keying noise is big, and easily by the husky obstruction of dirt, leakage rate is big up for opening.
The purpose of this utility model just provide a kind of highly sensitive, noise is little, high airtight low noise non-return safe and reliable, off-loading air outlet flue spaciousness subtracts valve.
The utility model solution is such: the other end at steel ball is installed guide's off-loading valve body, one end and the steel ball 8 of the piston 14 in this valve body are close to, the other end of piston withstands spring 16, one side of piston 14 is communicated with off-loading airduct 12, when air compressor air storage tank pressure does not reach rated pressure, piston 14 holds out against steel ball 8 and closes the off-load mouth under the elastic force effect of spring 16, after air compressor air storage tank pressure reaches rated pressure, modulating valve is opened, gas overflows and enters the left side of piston 14 through off-loading airduct 12, promoting piston 14 moves right, steel ball 8 is moved to right, open the off-loading mouth, realize off-loading, stifled the closing of non-return this moment, in case the service pipe gas pressure descends, the pressure regulator valve on the gas holder is in closed condition again, and the off-loading airduct did not have pressed gas and delivered in the valve this moment, piston 14 moves to left under the effect of spring 16, makes steel ball 8 seal off-loading mouth 9.
The utility model has the advantages that owing to adopt the pilot valve control mode, make it to reduce operational noise, it is reliable to be active in one's movements, off-loading air outlet flue spaciousness.
Accompanying drawing is embodiment of the present utility model:
Accompanying drawing 1 is the utility model structural representation.
The utility model is to be connected on the air compressor air storage tank with joint 1, adapter 3, anchor plate 4, spring 5, non-return stifled 7 are housed in the off-loading valve body 2, steel ball 8 is installed on off-loading mouth 9, one side at steel ball 8 is equipped with the off-loading pilot valve, this off-load pilot valve inner carrier 14, spring 16 are mounted on the valve body 15, and valve body 15 is to tighten on off-loading valve body 2 with screw thread.One end and the steel ball 8 of piston 14 are close to, and another side is held out against by spring 16, and spring 16 is to be contained on the spring seat 17, and spring seat 17 is to tighten on valve body 15 with screw thread, Regulation spring seat 17, the elastic force of adjustable springs 16.One side of piston 14 is communicated with off-loading airduct 12.
In the present embodiment, valve body 15 is to tighten on off-loading valve body 2 with screw thread, and off-loading airduct 12 is to be connected on the valve body 15 with joint 10, joint 11.Seal ring 13 is to be used for sealing.
Claims (4)
1, a kind of high airtight low noise non-return easing valve, include the joint 1, off-loading valve body 2, adapter 3, pilot pin 6, the non-return stifled 7 that connect gas tank, an end that it is characterized in that steel ball 8 is close to the piston 14 that is held out against by spring 16 elastic force, and one side of piston 14 is communicated with off-loading airduct 12.
2, the airtight low noise non-return of height according to claim 1 easing valve is characterized in that piston 14, and spring 16 is mounted on the valve body 15, and valve body 15 is to tighten on off-loading valve body 2 with the spiral shell mosquito.
3, the airtight low noise non-return of height according to claim 2 easing valve is characterized in that having on the valve body 15 spring seat 17 of adjustable springs 16 elastic force.
4, the airtight low noise non-return of height according to claim 2 easing valve is characterized in that off-loading airduct 12 is to be connected on the valve 15 with joint 10, joint 11.
