Abstract
The invention discloses a pneumatic proportional valve with a ceramic valve core. The pneumatic proportional valve comprises a valve body, an end cover and an electromagnet, wherein a ceramic valve sleeve is inserted and sleeved in the valve body; the ceramic valve core is inserted and sleeved in the ceramic valve sleeve; the ceramic valve core is a in a cylinder shape and the cylinder is provided with annular grooves; pores which are circumferentially distributed on the ceramic valve sleeve are corresponding to the annular grooves; an air inlet and an outlet are formed on the lateral side of the valve body; two ends of the valve body are respectively provided with a sealing groove; sealing rings are arranged inside the sealing grooves; and the end cover and the electromagnet are respectively fixed at the two ends of the valve body. The pneumatic proportional valve with the ceramic valve core has the advantages of being good in gas tightness of the integral structure, improving the sensitivity and response frequency and enabling working of the pneumatic proportional valve to be stable and the service life of the pneumatic proportional valve to be long due to the ceramic valve core and the ceramic valve sleeve which are high temperature resistant and deformation resistant.
Description
Technical field:
The present invention relates to the pneumatic proportional valve technical field, relate in particular to a kind of ceramic valve core pneumatic proportional valve.
Background technique:
Pneumatic proportional valve is that driving force and the input electrical signal of passing ratio electromagnet changes pro rata, the opening amount of control valve, thereby realize the delivery pressure of pneumatic proportional valve or a kind of novel pneumatic element of output flow and the proportional variation of input electrical signal, it is one of electrical integrated key element of realization gas one.
Existing pneumatic proportional valve kind is few, overall technology is more backward, Zheng Ti poor air-tightness particularly, and use metal material spool and valve pocket, weight and friction factor are all than higher, influenced whole sensitivity and response frequency, and under hot environment, easily deformed, stability and working life that influence is whole.
Summary of the invention:
Purpose of the present invention is exactly in order to solve existing issue, and a kind of ceramic valve core pneumatic proportional valve is provided, and the overall structure tightness is good, improves sensitivity and response frequency, working stability, and the life-span is long.
Technology solution of the present invention is as follows:
A kind of ceramic valve core pneumatic proportional valve includes valve body, end cap, electromagnet, be inserted with the ceramic valve cover in the valve body, ceramic valve pocket interpolation is with ceramic valve core, and described ceramic valve core is cylindrical body, have the circular groove of equal proportion position dimension on the cylindrical body, the pottery valve pocket circumferentially is distributed with pore and corresponding with the circular groove position, and the valve body side has suction port and delivery outlet, and the valve body two ends are respectively equipped with seal groove, be placed with seal ring in the seal groove, the valve body two ends are fixed with end cap and electromagnet respectively.
Preferably, described valve interior wall is provided with some annular grooves, and groove is corresponding with ceramic valve pocket pore position, and suction port is connected with groove with delivery outlet.
Preferably, described suction port and delivery outlet cross arrangement, be respectively horizontal two with two of Vertical direction.
Preferably, described ceramic valve core left end is inserted with positioning block, and positioning block is connected with spring.
Beneficial effect of the present invention is:
Overall structure tightness of the present invention is good, adopts ceramic valve core and the ceramic valve pocket of high temperature resistant resistance to deformation, and weight and friction factor are low, improves sensitivity and response frequency, makes the work of air valve more stable, and the life-span is longer.
