Abstract
The utility model relates to a vacuum air pump releaser improved structures comprising a stator and an outlet valve, wherein the top portion of the stator is provided with a socket, the socket and the fore and after cover of the pump body form an enclosed slot, the outlet port provided with a outlet valve is disposed on the bottom of the socket. Compared with the prior art, the utility model has the advantages that the valve plate airproof and the oil-tight working at the same time, simple structure, good airproof, high practicability or the like.
Description
Technical field
The utility model relates to a kind of vacuum pump, particularly a kind of structure-improved of vacuum pump venting gas appliance.
Background technique
The working principle of vacuum pump is from intakeport inspiration gas, and discharges gas from relief opening, thereby obtains certain degree of vacuum, and venting gas appliance is arranged on a leakproof one-way valve of relief opening, and its sealability has very big influence to the degree of vacuum quality that obtains.The outlet valve of existing vacuum pump comprises exhaust valve plate and banking stop, both are set together in stack, the one end is fixedly installed on the air outlet platform at stator (mercury vapour cylinder) top by screw, the other end blocks the air outlet and forms an one-way valve, during exhaust, the pressurized gas of stator interior back down valve block and realize exhaust, utilize the restoring force of banking stop to make exhaust valve plate block air outlet realization sealing again during end, its sealing mainly is to lean on the applying of exhaust valve plate and air outlet platform to realize, the oil of taking out of during exhaust also plays a part certain in addition, but existing air outlet hole platform is a plane, this makes the oil of taking out of be difficult to maintain, cause effect that oil sealing plays seldom, and vacuum pump is after long-time the use, the restoring force of banking stop can lose efficacy, also can be blocked between the faying surface of exhaust valve plate and platform simultaneously by greasy dirt, thereby cause gas leak phenomenon, cause the workmanship of vacuum pump to descend, degree of vacuum reduces.
The model utility content
The purpose of this utility model is to provide a kind of structure-improved of vacuum pump venting gas appliance, and it has characteristics simple in structure, good sealing effect in conjunction with exhaust valve plate and oil sealing dual mode.
For achieving the above object, the utility model is by the following technical solutions:
A kind of structure-improved of vacuum pump venting gas appliance comprises a stator and outlet valve, it is characterized in that: the top of described stator is provided with a groove, and the air outlet is positioned at bottom portion of groove, and an outlet valve is set on it.
Above-mentioned outlet valve comprises exhaust valve plate and the banking stop that stack is set together.
During use, before the groove at stator top and the vacuum pump, bonnet forms an enclosed slot together, this oil of taking out of with pressurized gas that makes remains at groove the inside formation one oil reservoir, its valve block in conjunction with outlet valve is realized double seal, high pressure air is backed down valve block and oil reservoir discharges outward when exhaust, utilize the restoring force of banking stop to make valve block block air outlet realization sealing again during end, oil reservoir utilizes its surface tension to realize oil sealing simultaneously, the vacuum pump that such structure makes is after long-time the use, even the restoring force of spring sheet lost efficacy, when perhaps being blocked by greasy dirt between the faying surface of exhaust valve plate and platform, oil reservoir also can guarantee the sealing of outlet valve.
Description of drawings

Embodiment
As shown in Figure 1, a kind of structure-improved of vacuum pump venting gas appliance, comprise a stator 1 and outlet valve 2, the top of stator 1 is provided with a groove 11, before itself and the vacuum pump, the bonnet (not shown) forms an enclosed slot together, air outlet 12 is positioned at groove 11 bottoms, outlet valve 2 is set on it, outlet valve 2 comprises exhaust valve plate 21 and the banking stop 22 that stack is set together, the oil of taking out of with pressurized gas during work remains at the groove the inside and forms an oil reservoir, its exhaust valve plate 21 in conjunction with outlet valve 2 is realized double seal, even after the long-time use of vacuum pump, restoring force at banking stop 22 lost efficacy, and when perhaps being blocked by greasy dirt between the faying surface of exhaust valve plate 21 and groove 11, oil reservoir also can guarantee the sealing of outlet valve 2.
In a word, the utility model mode organically combines both in conjunction with exhaust valve plate and oil sealing dual mode, has characteristics simple in structure, good sealing effect.
Claims (2)
