Description
Technical field
Gasoline engine field is the utility model is related to, in particular, the utility model is related to a kind of double-layer balance device.
Background technology
At present, although the qualification rate of the balancer leak test of prior art manufacture reaches 90% more than, but is to fit into machine
Still needed when upper and examine one by one, waste of manpower, balancer needs to use preferable rubber raw materials just to can guarantee that at valve body openings
Miscella is not revealed, cost is higher.
Utility model content
The purpose of this utility model is to solve the problems, such as existing above-mentioned, there is provided a kind of double-layer balance device.
To realize object above, the technical solution of the utility model is a kind of double-layer balance device, it is characterized in that, including housing
With upper lid, upper lid is fixedly connected with the casing, and described enclosure interior sets the first valve, and the first described valve detachably connects with housing
Connect, the second valve is set in the first described valve, the second described valve is detachably connected with the first valve.Fixed by housing and upper lid
First valve and the second valve, the second valve is added inside original first valve, in the case where the first valve is ineffective, the second valve can
To work, dual wheel leakage protective can be so played, it is not necessary to pay attention to examining part, save manpower.
Optionally, link slot is set on the first described valve outer wall, set on described housing corresponding with link slot
Butt joint ring.Link slot on first valve is corresponding with the butt joint ring on housing, for the sealing between housing and the first valve, prevents
Gas leakage.
Optionally, bulge loop is set on the second described valve outer wall, set on the first described valve inwall corresponding with bulge loop
Groove.Bulge loop on second valve is corresponding with the groove of the first valve inwall, for the sealing between the first valve and the second valve, prevents
Leak-stopping gas.
Optionally, pressure pipe is set in described upper lid, and described pressure pipe is fixedly connected with upper lid.Pressure pipe in upper lid is used for
The first valve and the second valve are pushed down, plays fixed spacing effect.
Optionally, foam-rubber cushion is set between described housing and upper lid, and described foam-rubber cushion is set in outside pressure pipe.Sponge
Pad the oil or other impurities for being absorbed into balancer.
Optionally, connection ring is set on described housing, and described connection ring is fixedly connected with the casing.Connection ring be used for
Other parts connect, and can play a part of preventing from coming off.
The utility model has the advantages that：First valve and the second valve are fixed by housing and upper lid, original the
The second valve is added inside one valve, in the case where the first valve is ineffective, the second valve can work, and can so play double
Weight wheel leakage protective, it is not necessary to pay attention to examining part, save manpower.

Embodiment
With reference to specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is further described：
Embodiment：Double-layer balance device (see accompanying drawing 1-5), including housing 2 and upper lid 1, upper lid 1 are fixedly connected with housing 2, institute
The inside of housing 2 stated sets the first valve 4, and the first described valve 4 is detachably connected with housing 2, setting the in the first described valve 4
Two valves 5, the second described valve 5 are detachably connected with the first valve 4, and link slot 9 is set on the described outer wall of the first valve 4, described
The butt joint ring 8 corresponding with link slot 9 be set on housing 2, setting bulge loop 10 on the described outer wall of the second valve 5, described first
The groove 11 corresponding with bulge loop 10 is set on the inwall of valve 4, pressure pipe 7, described pressure pipe 7 and upper lid 1 are set in described upper lid 1
It is fixedly connected, foam-rubber cushion 6 is set between described housing 1 and upper lid 2, and described foam-rubber cushion 6 is set in outside pressure pipe 7, described
Housing 2 on connection ring 3 is set, described connection ring 3 is fixedly connected with housing 2.
The application fixes the first valve and the second valve by housing and upper lid, and the second valve is added inside original first valve,
In the case where the first valve is ineffective, the second valve can work, and can so play dual wheel leakage protective, it is not necessary to pay attention to
Part is examined, saves manpower, the link slot on the first valve is corresponding with the butt joint ring on housing, between housing and the first valve
Sealing, prevent gas leakage, the bulge loop on the second valve is corresponding with the groove of the first valve inwall, between the first valve and the second valve
Sealing, prevent gas leakage, the pressure pipe in upper lid is used to push down the first valve and the second valve, plays fixed spacing effect, foam-rubber cushion
For the oil or other impurities being absorbed into balancer, connection ring is used to be connected with other parts, and can play prevents
The effect to come off.
Above-mentioned embodiment is used for illustrating the utility model, rather than the utility model is limited,
Spirit of the present utility model and any modifications and changes in scope of the claims, made to the utility model, all fall
Enter the scope of protection of the utility model.
