Description
Technical field
The utility model relates to a kind of combination brake switch and proporting, and particularly the reciprocating vacuum pump combination brake switch and proporting belongs to the transformation of W3 type vacuum pump attachment technique.
Background technique
Present general reciprocating vacuum pump, industry common name W3 vacuum pump, its suction and discharge combination brake switch and proporting, Aspirating valves directly is pressed on the suction valve chip with spring, causes that spring easily comes off, suction valve chip easily is shifted, and guidance quality is not strong, functional reliability is not high, and valve seat, valve block are easy to wear.Suction valve chip and spring come off easily to be sucked into and cause the cylinder body wearing and tearing in the cylinder, reduce the vacuum pump performance, even the danger that has cylinder body to scrap.
The model utility content
Technical problem to be solved in the utility model is, at above combination brake switch and proporting deficiency, a kind of reciprocating vacuum pump combination brake switch and proporting is proposed, mainly be that the suction valve chip assembly is improved, its suction and discharge energy Reasonable Orientation has very strong guidance quality, and working stability is reliable, the nonabradable characteristics of valve block, the working life of prolongation valve seat and valve block.
The technological scheme that the utility model is dealt with problems is: a kind of reciprocating vacuum pump combination brake switch and proporting comprises valve body, valve seat, outlet valve and Aspirating valves; Valve seat is positioned on the valve body, and air intake passage, Aspirating valves, exhaust passage and outlet valve are arranged on the valve body; The exhaust port of outlet valve is elongated on the valve seat, is divided into three five equilibriums by two divider arms; Bore the silk hole on the divider arms outlet valve positioning screw is installed; The long strip exhaust valve plate is the boring of corresponding position in divider arms silk hole, is placed on the positioning screw, has nut, outlet valve pressing plate and exhaust valve spring that the long strip exhaust valve plate is compressed on positioning screw; Above-mentioned Aspirating valves is to have two Aspirating valves positioning screws to be loaded on the silk hole, Aspirating valves location in the exhaust passage; Every Aspirating valves positioning screw one end is a screw mandrel, and the other end is a locating stud; On the corresponding position of Aspirating valves pressing plate positioning hole is arranged also, long strip suction valve chip, Aspirating valves spring, Aspirating valves pressing plate are placed in respectively on the Aspirating valves positioning screw, and the Aspirating valves pressing plate is locked by screw rod.
All there is concave station the spring position of above-mentioned Aspirating valves pressing plate and the spring position of outlet valve pressing plate, are used for retaining spring.
Above-mentioned Aspirating valves positioning screw, outlet valve positioning screw also are commonly referred to as Aspirating valves and lead with outlet valve and lead in engineering term.
The effect of the utility model spring is used for resetting of valve block.
Reciprocating vacuum pump combination brake switch and proporting of the present utility model, adopt long strip suction, exhaust valve plate, spacing by Aspirating valves positioning screw and outlet valve positioning screw respectively, and spring reset is arranged, suction, exhaust valve plate energy Reasonable Orientation, guidance quality is good during motion, and suction, exhaust valve plate are the plane of even little width with contacting of valve seat, and is stressed even, this suction, exhaust valve plate can increase more than 20～30 times working life, maintenance frequency reduces, and has improved manufacturing efficiency, has reduced cost.
