Abstract
A corrosion resistant vertical type reciprocating vacuum pump suction valve comprises a valve body, a valve seat, an exhaust valve and a suction valve and is characterized in that the valve seat is arranged on the valve body. The valve body is provided with a suction channel, the suction valve, an exhaust channel and the exhaust valve. Exhaust holes of the exhaust valve on the valve seat are in the shape of a long strip and divided into three equal parts by two separating arms. A nut, an exhaust valve pressing plate and an exhaust valve spring are arranged on a locating screw for pressing a long-strip-shaped exhaust valve sheet. The suction valve is installed by arranging two suction valve locating screws in a suction valve locating screw hole in the exhaust channel, locating holes are further arranged at corresponding positions of a suction pressing plate, a long-strip-shaped suction valve sheet, a suction valve spring and the suction valve pressing plate are respectively sleeved on the suction valve locating screws, and the suction valve pressing plate is locked by a screw. The corrosion resistant vertical type reciprocating vacuum pump air suction valve is reasonable in locating, good in orientation of movement, stable in working opening and long in service life.
Description
Technical field
The utility model relates to a kind of vacuum pump combination brake switch and proporting, particularly relates to the vertical reciprocating pump Aspirating valves of a kind of corrosion resistant.
Background technique
Present general vertical reciprocating pump, industry common name corrosion resistant vertical type 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 is prone to come off, suction valve chip is prone to displacement, and guidance quality is not strong; Functional reliability is not high, and valve seat and valve block are easy to wear, and suction valve chip and spring come off to be prone 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
The utility model technical problem to be solved is to above Aspirating valves deficiency, to propose the vertical reciprocating pump Aspirating valves of a kind of corrosion resistant; Mainly be that the suction valve chip assembly is improved; Its suction and discharge ability 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:
The vertical reciprocating pump Aspirating valves of a kind of corrosion resistant comprises valve body, valve seat, outlet valve and Aspirating valves, and it is characterized in that: 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 equal portions 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, and nut, outlet valve pressing plate and exhaust valve spring are arranged on positioning screw, and the long strip exhaust valve plate is compressed; Aspirating valves is in the exhaust passage, to have two Aspirating valves positioning screws to be loaded on the silk hole, Aspirating valves location, and every Aspirating valves positioning screw one end is a screw mandrel, and the other end is a locating stud; On the corresponding position of air-breathing pressing plate, positioning hole is arranged also, long strip suction valve chip, Aspirating valves spring and 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 Aspirating valves pressing plate and the spring position of outlet valve pressing plate, are used for retaining spring.
Aspirating valves positioning screw and 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.
The vertical reciprocating pump Aspirating valves of a kind of corrosion resistant of the utility model adopts long strip suction, exhaust valve plate, and is spacing by Aspirating valves positioning screw and outlet valve positioning screw respectively; And spring reset is arranged, suction, exhaust valve plate ability Reasonable Orientation, guidance quality is good during motion; Suction, exhaust valve plate are the plane of even little width with contacting of valve seat, and 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.
