Abstract
The utility model relates to a compressor cylinder composite pressure adjusting device comprising a compressor cylinder (1) and a piston rod component (2), an adjusting cylinder (6) is arranged in an adjusting hole of the cylinder (1), and an adjusting piston rod (5) is arranged in the adjusting cylinder (6). The compressor cylinder composite pressure adjusting device is characterized in that a pressure spring (14) is arranged on the adjusting piston rod (5) to be matched with the adjusting cylinder (6), and a step hole (13) is formed in the center of the adjusting piston rod (5), wherein a steel ball (12), a plunger piston (11), a spring (10) and an end screw (9) are sequentially arranged in the step hole. Compared with a device adopting a traditional pressure adjusting method which is achieved by adjusting the thickness of an air valve washer and the thickness of a gasket between cylinders, the compressor cylinder composite pressure adjusting device is larger in adjustable pressure range; and due to the fact that the step hole is formed in the center of the adjusting piston rod, and the steel ball, a slider, the spring and the end screw are sequentially arranged in the step hole to constitute the composite adjusting device, pressure in the cylinder is enabled to be more meticulous.
Description
Technical field
The utility model relates to compresser cylinder, especially is mainly used in needing to change the compound controlling device of compresser cylinder pressure of compressor interstage pressure.
Background technique
The size of each stage pressure of compressor depends mainly on the ratio of the swept volume of cylinder except outside the Pass having with leakages such as piston ring, air valve, pipelines.
Can the size of each stage pressure of compressor has influence on the stressing conditions of piston, finally be reflected in piston rod and bear in the course of the work, adjusts each stage pressure and will reduce piston force exactly.Simultaneously, the ratio size of each stage pressure influences the delivery temperature after the compression again.
After the compressor design manufacturing was finished, appearance actual pressures at different levels and design pressure had certain deviation in the commissioning process, but the situation that must adjust.
Traditional adjustment mode is: adjust the air valve gasket thickness in the compresser cylinder parts, the methods such as spacer thickness between the cylinder, but adjustable scope is less; Though the scope of adjusting with the method that changes the cylinder and piston diameter is big, the process-cycle is long, cost of production is high.
The model utility content
The purpose of this utility model is exactly to be difficult to satisfy the defective of job requirement in order to overcome existing pressure regulator, and provides a kind of compresser cylinder pressure compound controlling device.
The technological scheme that its technical problem that solves the utility model adopts is:
The compound controlling device of compresser cylinder pressure, comprise compresser cylinder, be provided with piston rod part in the cylinder chamber of compresser cylinder, cylinder body at compresser cylinder is provided with adjustment hole, be provided with the adjusting cylinder in the adjustment hole, regulating cylinder communicates with cylinder chamber, regulate in the cylinder and be provided with the regulating piston bar, regulating piston bar one end is provided with seal ring and cooperates with the adjusting cylinder inner wall, the other end is that threaded end is connected with the female end of regulating cylinder, it is characterized in that: the regulating piston bar is provided with pressure spring 14 and cooperates with the adjusting cylinder; Regulating piston bar center is provided with shoulder hole, wherein is provided with plunger, spring and termination screw in the shoulder hole successively.
On the basis of technique scheme, following further technological scheme can be arranged:
Being provided with steel ball in the shoulder hole of regulating piston bar cooperates with plunger.
The beneficial effects of the utility model are the compound controlling devices of compresser cylinder pressure, compare with the spacer thickness adjusting pressure method that traditional passing through regulated between air valve gasket thickness, the cylinder, and adjustable pressure range is big; Because regulating piston bar center is provided with shoulder hole, wherein be provided with the compound controlling device that steel ball, slide block, spring and termination screw are formed successively, the inner pressure of air cylinder that is is more careful.
Below in conjunction with drawings and Examples the utility model is further specified.
