Abstract
The utility model discloses a W-shaped vacuum pump circular combination valve for controlling the W-shaped reciprocating vacuum pump to charge or discharge the pumped gas and relates to the improving technology of the accessory of a vacuum pump. The circular combination valve is provided with a valve body and the valve body is provided with valve seats. Every valve seat is provided with more than two gas valves and every gas valve is provided with a circular valve piece. The valve piece is fixed by a valve guide, a spring, etc. The combination valve has good guidance quality in the process of the movement of the valve piece and the contact force of the valve piece and the valve seats is uniform. The valve piece of the combination valve has longer service life comparing to an original sliver-shaped valve piece.
Description
The utility model belongs to field of vacuum, relates to the improvement technology of vacuum pump annex, is to be used for W type reciprocating vacuum pump to being extracted the combination brake switch and proporting that gas carries out air inlet or exhaust control.
The inlet and outlet control valve of existing W type reciprocating vacuum pump generally is to adopt the long strip valve block, and valve block directly contacts with valve body, and guidance quality was poor during valve block opened and closed; The valve block impact force is bigger on the other hand, and the contact stress on the valve block bump valve seat is inhomogeneous, and therefore, valve block short, increase cost in working life reduces working efficiency owing to often changing valve block; The concentrated wear of valve body simultaneously is fast, has influenced the life-span of sealability and valve body.
The purpose of this utility model is the valve block of a kind of ring-type shape of design, a plurality of ring-shaped valves are installed on the valve seat and form combination valve, is applicable to that W type vacuum pump is carried out that air inlet and exhaust control, the combination brake switch and proporting of long service life to extracting gas.
Technical solution of the present utility model is a valve body, valve seat is installed on the valve body, plural air valve passage is arranged on each valve seat, the valve block and the valve block fixed mechanism of a ring-type shape arranged on each air valve passage, its fixed mechanism is the spring that the valve of guiding valve plate movement leads and make valve block to reset.Valve seat is generally long strip, and corresponding with the suction port or the relief opening of valve body, valve seat can be installed on the valve body by screw.Plural valve opening is arranged on the valve seat, valve orifice has the seal boss of inside and outside two rings not of uniform size, the external diameter of cylindrical annular seal boss is consistent with the external diameter of valve block, and the location endoporus in the interior ring partly matches with the double-screw bolt that valve is led, and has muscle to link to each other between two annulus.Valve block is toroidal, and the pilot hole at valve block center matches with the roundlet cylinder that valve is led, and valve block is led along valve and moved during work, and the upper limit of movement of valve block is the lower end surface of the valve big column of leading, and valve block links to each other with spring, and spring plays reset response to valve block.Valve guide is gone into valve block and spring, passes valve seat location endoporus again, and the double-screw bolt part of leading at valve is installed on the valve seat by pad and nut.
Ring-type combination brake switch and proporting of the present utility model at the air valve that has on each valve seat more than 2, is generally 4～6 for good, and each air valve is made up of the institutes such as hold-doun nut that valve block, valve are led, spring and valve are led.
Vacuum pump combination brake switch and proporting of the present utility model, adopt the valve block of ring-type shape, the annular valve block is led fixing and spring reset by valve, guidance quality is good during valve plate movement, and valve block is the circumferentia of even little width with contacting of valve seat, and is stressed even, this valve block working life, the valve block than former long strip increased more than 20～30 times, maintenance frequency reduces, and has improved manufacturing efficiency, has reduced cost.
