Abstract

The utility model relates to an aerofluxus type cylinder head, which is composed of a piston cavity, a piston, a piston rod, valve sheets, and springs. One side of the air inlet of a cylinder cover is provided with the piston cavity, and the inside of the cavity is provided with the piston and the piston rod. The lower end of the piston rod is provided with the valve plate, and the lower part of the piston is provided with the spring. The upper part of the piston cavity is provided with one cavity cover, and the middle of the cavity cover is provided with a joint. The utility model can combines the cylinder and a relief device together and can automatically unload when the air pressure of the air storage tank of a compressor reaches prescribed values. The compressor can continuously run without loads. The damage of the compressor can be avoided, and the service life of the compressor can be prolonged. The utility model has the advantages of compact structure and lower cost.

Description

Disappointing formula cylinder head

The utility model belongs to a kind of mechanical part, more precisely a kind of disappointing formula cylinder head of compressor.

Though multiple off-load form is also arranged, all there are shortcomings such as loosely organized, complex process in various compressors of Xiao Shouing in the market.

The purpose of this utility model is: provide a kind of compact structure, technology simple, be installed in the disappointing formula cylinder head in the cylinder head.

The purpose of this utility model realizes as follows: air-inlet cavity one side in cylinder head, arrange a piston cavity, be equipped with in the chamber on piston, piston rod, spring and the valve block piston cavity valve gap is arranged, cover and joint is housed is connected with the prior art pressure regulator valve, the suction port of piston cavity bottom and cylinder joins.When the gas tank internal pressure surpassed preset value, under the effect of pressure regulator valve, the elasticity that piston overcomes spring moved down piston rod, thereby the valve block of piston-rod lower end reaches zero load work purpose with the inlet close of cylinder.

Advantage of the present utility model: molten cylinder and relief arrangement are in one, can automatic deloading when compressor gas tank air pressure reaches specified value, compressor is remained in operation under zero load, avoid damaging compressor and prolong its working life, compact structure, cost of production is lower.

Below in conjunction with accompanying drawing the utility model is further elaborated:

Accompanying drawing is a sectional view of the present utility model.

Referring to accompanying drawing, in cylinder head 1 suction port 2 one sides, a columniform piston cavity 3 is arranged, a piston 4 is housed in the chamber, there is the seal ring 5 of an annular at the piston middle part, and piston top is spill, and piston rod 6 is fixing by the 7 usefulness nuts 8 of the hole in the middle of the piston bottom.Piston-rod lower end is equipped with a circular valve block 9, is also fixed by nut 10.Around in the piston bottom groove 11 is arranged, spring 12 is embedded in the groove.One chamber lid 13 is arranged at piston cavity top, is fixed on the cylinder head with screw 14.In the middle of the lid of chamber a joint 15 is arranged.2 one-tenth up big and down small stepped shafts of suction port, the diameter of valve block 9 is less than the suction port upper end diameter, greater than the suction port lower end diameter.
