Part and the up and down connection of the connecting seat, the internal diameter of the exhaust events head are less than the internal diameter of connecting seat, the exhaust events
Head is connected with the air inlet pipe, and when the hyperbar gas of gas cylinder enters the pump housing by air inlet pipe, exhaust events head is in hyperbar
Moved straight up relative to connecting seat in the presence of gas, in gap of the hyperbar gas between exhaust events head and connecting seat
Overflow to protect the pump housing.
As the further improvement of such scheme, exhaust events head include the tubular junction that is connected with air inlet pipe with
And it is connected to the ring-type limiting section of tubular junction lower end.
As the further improvement of such scheme, the caliber of the tubular junction is gradually reduced axially upwards along it.
As the further improvement of such scheme, the limiting component is fixedly installed on the inwall of ring-type limiting section.
As the further improvement of such scheme, the limiting component includes being fixedly mounted on ring-type limiting section inwall and erecting
The straight-bar that directly extends downwardly and the limited block for being fixedly connected on straight-bar lower end.
The beneficial effects of the utility model are：This vavuum pump is by protection device to protect the pump housing, and protection device utilizes company
Joint chair is arranged on the pump housing, and exhaust events head is by limiting component and the up and down connection of connecting seat, when the high gas of gas cylinder
When body of calming the anger enters the pump housing by air inlet pipe, exhaust events head relative connecting seat in the presence of hyperbar gas is moved straight up
It is dynamic so that hyperbar gas overflows in the gap between exhaust events head and connecting seat, and the utility model passes through protection device
Pressure release is effectively carried out, infringement of the gases at high pressure to the pump housing is reduced, extends the service life of the pump housing.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain according to these accompanying drawings
Other designs and accompanying drawing：
Fig. 1 is the structural representation of the utility model preferred embodiment；
Fig. 2 is the structural representation of protection device in the utility model preferred embodiment；
Fig. 3 is Fig. 2 sectional view.
Embodiment
The technique effect of design of the present utility model, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belongs to the model of the utility model protection
Enclose.
Referring to figs. 1 to Fig. 3, a kind of vavuum pump with protection device, including base 1 are provided with the pump housing on the base 1
2, impeller is provided with the pump housing 2, and the base 1 is provided with the motor 3 being connected with the impeller in the side of the pump housing 2, described
Air inlet pipe 5 is connected with by a protection device 4 on the pump housing 2, the air inlet pipe 5 is connected with gas cylinder to be vacuumized, and the pump housing 2 also connects
Blast pipe 6 is connected to, blast pipe 6 is used to gas being discharged into air.The protection device 4 includes the company being arranged on the pump housing 2
Joint chair 41 and the exhaust events being placed on connecting seat 41 first 42, specifically, the exhaust events first 42 include and air inlet pipe 5
The tubular junction 421 of connection and the ring-type limiting section 422 for being connected to the lower end of tubular junction 421.The tubular junction
421 caliber is gradually reduced axially upwards along it.The exhaust events first 42 are by limiting component 7 and the connecting seat about 41
It is flexibly connected, the internal diameter of the exhaust events first 42 is less than the internal diameter of connecting seat 41, because the internal diameter of exhaust events first 42 is less than
The internal diameter of connecting seat 41, so that exhaust events first 42 are more prone to move up in the presence of gases at high pressure.The row
Gas movable head 42 is connected with the air inlet pipe 5.Specifically, the limiting component 7 is fixedly installed on the inwall of ring-type limiting section 422
