Abstract
The utility model relates to a control valve of a gas compressor. The control valve of the gas compressor comprises a valve seat and a valve cover, a cavity is arranged between the valve seat and the valve cover, a plurality of first through holes are formed in the valve seat, a plurality of second through holes are formed in the valve cover, a plurality of third through holes are formed in the valve cover and correspond to the first through holes, valve cores are arranged in the third through holes, one ends of the valve cores are positioned in the third through holes, and the other ends of the valve core can close or open the first through holes. Grooves are arranged in the valve cores, springs are arranged in the grooves, and the other ends of the springs are connected with the valve cover. One valve core is arranged in each first through hole correspondingly, when the valve cores are damaged, only the damaged valve cores need replacing, and using cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of gas compressor device, relates to specifically a kind of gas compressor control valve.
Background technique
Gas compressor is the main body in the compressed air source unit, and it is the device that the mechanical energy of prime mover is converted to the gas pressure energy, is the pressure generator of pressurized gas.The kind of gas compressor is a lot, can be divided into positive displacement compressor and speed mode compressor by working principle, and the working principle of positive displacement compressor is the volume of pressurized gas, makes the density of gas molecule in the per unit volume increase to improve compressed-air actuated pressure; The working principle of speed mode compressor is to improve the movement velocity of gas molecule, and the kinetic transformation that gas molecule is had is the pressure energy of gas, thereby improves compressed-air actuated pressure.
The employed control valve of gas compressor comprises the parts such as valve seat, valve gap and spool now, be provided with several through holes on the valve seat, opening or sealing by spool control through hole, present employed spool is structure as a whole mostly, when spool damages, whole spool need to be changed, greatly increase user cost.
The model utility content
Problem to be solved in the utility model is for above problem, provides a kind of user cost low gas compressor control valve.
For addressing the above problem, the technological scheme that the utility model adopts is: a kind of gas compressor control valve, comprise valve seat and valve gap, has cavity between described valve seat and the valve gap, be provided with several the first through holes on the described valve seat, be provided with several the second through holes on the described valve gap, be provided with several third through-holes corresponding with the first through hole on the described valve gap, be provided with spool in the described third through-hole, one end of described spool is positioned at third through-hole, and the other end of described spool can or be opened the sealing of the first through hole, is provided with groove on the described spool, be provided with spring in the described groove, the other end of described spring is connected with valve gap.
A kind of concrete optimized project is provided with locating stud between described valve seat and the valve gap.
A kind of concrete optimized project, described valve seat is fixedly connected with by screw bolt and nut with valve gap.
The utility model is taked above technological scheme, has the following advantages: each first through hole correspondence arranges a spool, and when spool was damaged, the spool replacing that only needs to damage got final product, and greatly reduces user cost.
The utility model is described in further detail below in conjunction with drawings and Examples.
