Abstract
The utility model discloses a safety valve, which is matched with an air compressor. The safety valve is composed of a press cover, a spring, a locking nut, a valve body, a valve flap, and a sealing pad. One part of the sealing surface of a valve seat contacts the sealing pad, and the other part thereof contacts the valve flap; the periphery of the bearing surface of the valve flap is provided with a gas hood connected with the valve flap into one body. The safety valve has the advantages that the sealing performance is good, the leakage rate is more than 50 percents lower than the Chinese standard, the operation is sensitive and reliable, the service is long, the processing and the assembly are simple, parts are few, the size is small, the weight is light, the cost is low, etc.; the safety valve can also be used a safety device of an ordinary pressure vessel.
Description
The utility model belongs to a kind of spring Fall lift safety valve, the particularly a kind of and matching used safety valve of air compressor system.
Existing and the matching used safety valve of air compressor system generally adopts plane sealing, conical surface seal or steel ball sealing, and owing to Sealing all contacts with sealing surface of seat, and the anti-impact force of Sealing is relatively poor, so the life-span of safety valve is shorter.Above-mentioned several seal form difficulty of processing is big, is difficult to reach required precision, therefore causes the safety valve poor sealing performance, and its leakage rate is difficult to reach the relative national standards requirement.
The purpose of this utility model is to provide a kind of work sensitive reliable, good seal performance, and simple safety valve is processed and assembled to long service life.
For achieving the above object, solution of the present utility model is to inlay sealing gasket in the bottom of flap, and the part of sealing surface of seat contacts with sealing gasket, and its another part contacts with flap.
Safety valve provided by the utility model is compared with existing safety valve, has following advantage:
1, good seal performance proves that after tested its leakage rate is lower than NBS more than 50%.
2, work is sensitive reliable, long service life.
3, part is few, and processing and assembling are simple, and volume is little, cost is low (littler by 2/3 than similar safety valve, the low 1-2 of cost doubly), and is in light weight.
Below in conjunction with drawings and Examples concrete structure of the present utility model is described further:
Fig. 1--be structural representation of the present utility model.
As shown in the figure, the safety valve of the utility model is made up of gland 1, spring 2, locking nut 3, valve body 4, flap 5, sealing gasket 6.Gland 1, locking nut 3, valve body 4, flap 5 all adopt cast copper to make, make sealing gasket 6 with fluorine rubber, valve seat and valve body 4 are made one in the present embodiment, flap 5 is packed in the valve body 4, the bottom of flap 5 is inlaid with sealing gasket 6, and the part of sealing surface of seat contacts with sealing gasket 6, and its another part contacts with flap 5, so both guaranteed that gas does not leak, and had prolonged the working life of sealing gasket again.The gas hood that fuses with flap 5 is arranged to form air cushion around flap 5 pressure-bearing surfaces, guarantee the reliability of flap action, on the pressure-bearing surface of sealing gasket 6, have annular groove, can improve the gas flow situation, further improve functional reliability.Spring 2 is equipped with on the top of flap 5, by locking nut 3 gland 1 is locked on the valve body 4, and the profile of valve body 4 can be made into circular or square or hexagon etc.
As a kind of conversion of the present utility model, can set up valve rod and pack in the valve body 4, also valve rod and flap 5 can be fused, the safety valve suction port also can be made into cylindrical.
