PROCEDURE FOR SEALING AND DEVICE OF ELECTRO-MAGNETIC VALVE OF HIGH PRESSURE |
摘要 |
FIELD: machine building. ^ SUBSTANCE: procedure for sealing electromagnetic valve of high pressure consists in its sealing in closed position by interaction between metal circular edge of seat and shut-off element under high pressure of working substance actuating spring and in valve opening by said spring squeezing and shut-off element opening with force of electro-magnet when is fed with electric current. The shut-off element has conic working surface. The seat with the edge is made on flat surface whereon there is placed a packing in form of an elastic film ring, An external end of the said ring is rigidly attached to said flat surface. An internal end of the ring has a lug over the edge of the seat; it is pressed inside with offset of the internal end of the ring into a side of its periphery increasing pressure tightness. There is disclosed the device for implementation of the said procedure. ^ EFFECT: raised reliability of operation of electro-magnetic valve and its increased resource by increased degree of its closure tightness. ^ 3 cl, 2 dwg |
