Abstract
The utility model discloses a ceramic valve element pneumatic proportional valve which comprises a valve body, an end cap, and an electromagnet. A ceramic valve sleeve is inserted into the valve body. A ceramic valve element is inserted into the ceramic valve sleeve. The ceramic valve element is a cylinder. Annular grooves are formed in the cylinder. Air holes are formed in the ceramic valve sleeve in the circumferential direction and the positions of the air holes correspond to those of the annular grooves. Air inlets and outlets are formed in the side surface of the valve body. The two ends of the valve body are respectively provided with a sealing groove. A sealing ring is arranged in each sealing groove. The two ends of the valve body are fixed with the end cap and the electromagnet respectively. The ceramic valve element pneumatic proportional valve is good in gas tightness of the overall structure, and capable of improving the sensitivity and the response frequency. Due to the fact that the high-temperature-resistant anti-deformation ceramic valve element and the high-temperature-resistant anti-deformation ceramic valve sleeve are adopted, the ceramic valve element pneumatic proportional valve is stable in work and long in service life.
Description
Technical field:
The utility model relates to the pneumatic proportional valve technical field, relates 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 to realize one of key element that gas one is electrical integrated.
Existing pneumatic proportional valve kind is few, overall technology is more backward, whole poor air-tightness particularly, and use metal material spool and valve pocket, weight and friction factor are all higher, affected whole sensitivity and response frequency, and easily deformed under hot environment, stability and working life that impact is whole.
The model utility content:
The purpose of this utility model 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 utility model is as follows:
A kind of ceramic valve core pneumatic proportional valve, include valve body, end cap, electromagnet, be inserted with ceramic valve pocket in valve body, ceramic valve pocket interpolation cover has ceramic valve core, and described ceramic valve core is cylindrical body, have the circular groove of equal proportion position dimension on 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 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.
The beneficial effects of the utility model are:
The utility model overall structure tightness 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.
