Abstract
The utility model provides a clearance adjusting device of a compressor air cylinder. The clearance adjusting device of the compressor air cylinder resolves the problems that the compressor has a requirement for the adjustment of a particular parameter air flow, and a traditional unloading device can not meet the requirement. The clearance adjusting device of the compressor air cylinder is characterized in that a valve hole is formed in an air cylinder cover, a clearance valve controlling the valve hole is arranged on the air cylinder cover, the clearance valve comprises a valve seat, a core shaft passageway is arranged in the center of the valve seat, a core shaft is arranged in the core shaft passageway, an outer end and an inner end of the core shaft are respectively used for fixing a piston and controlling a valve deck of the valve hole, the piston is located in a valve cavity formed by a valve cover and the valve seat in a surrounding cavity, a spring is arranged in the piston and the valve seat, the spring and a rule are arranged in a cavity A of the valve cavity, and instrument air enters a cavity B of the valve cavity through an air pipe. The clearance adjusting device of the compressor air cylinder has the advantages that manual adjustment of the clearance valve is not needed, and the motion of the clearance valve can be observed through the rule.
Description
Technical field
The utility model relates to the compresser cylinder clearance adjusting device.
Background technique
Compressor need be regulated a certain amount of clearance.For satisfying the tolerance requirement of compressor, conventional unloader can not satisfy the tolerance that Compressor Process requires.Although stepless tolerance is regulated and can be realized, require control complicated, increased cost of production.
The model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of compresser cylinder clearance adjusting device that can solve above-mentioned deficiency.
The purpose of this utility model is achieved in that it comprises the cylinder head of gas compressor, is characterized in that: open a valve opening that communicates with the gas compressor cylinder inner cavity in cylinder head, the clearance valve of controlling this valve opening is installed on the cylinder head; The clearance valve comprises valve seat, this valve seat uses bolt to be installed on the cylinder head, center at valve seat arranges mandrel channel, and mandrel is arranged in the mandrel channel, and the outer end of mandrel and inner end be fixed piston and the flap of controlling valve opening respectively, piston is in valve pocket, valve pocket is surrounded by valve gap and valve seat, between piston and valve seat spring is set, and the through hole that the inner end of chi is passed on the valve seat is fixed on the piston, spring and chi are in the A chamber of valve pocket, and instrument wind enters in the B chamber of valve pocket by airduct.The stroke that the instrument wind that the clearance valve gap provides by system and spring are controlled clearance valve piston, mandrel and flap successively, and then the on off state of control valve opening realize that cylinder clearance regulates.Chi is observed the length that chi stretches out along with the stroke of piston moves back and forth, and can understand the action of piston and then clearance valve.
Compared with prior art, the beneficial effects of the utility model are:
1, the clearance valve does not need manual tune, can observe the clearance valve events by chi;
2, motion is steadily regulated accurately good seal;
3, simple in structure, be convenient to dismounting and maintenance, do not need complicated electrical control;
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
It comprises the cylinder head 5 of gas compressor, opens a valve opening 6 that communicates with the gas compressor cylinder inner cavity in cylinder head, and the clearance valve of controlling this valve opening is installed on the cylinder head; The clearance valve comprises valve seat 4, this valve seat uses bolt to be installed on the cylinder head, center at valve seat arranges mandrel channel, mandrel 7 is arranged in the mandrel channel, the outer end of mandrel and inner end be fixed piston 2 and the flap 9 of controlling valve opening respectively, mandrel 7 is the conical surface with the sealing surface of valve opening 6, needs during assembling to grind, and makes stem seal face tight with the sealing of cover.Piston 2 is in valve pocket, and valve pocket is surrounded by valve gap 1 and valve seat, and spring 8 is set between piston and valve seat, and the through hole that the inner end of chi 3 is passed on the valve seat is fixed on the piston, and spring and chi are in the A chamber of valve pocket, and instrument wind enters in the B chamber of valve pocket by airduct 10.The stroke that the instrument wind that the clearance valve gap provides by system and spring are controlled clearance valve piston, mandrel and flap successively, and then the on off state of control valve opening realize that cylinder clearance regulates.Chi is observed the length that chi stretches out along with the stroke of piston moves back and forth, and can understand the action of piston and then clearance valve.
Only need during dismounting valve seat and cylinder head attaching nut are turned on, clearance valve and cylinder head are thrown off.
