Technical field
The utility model relates to a kind of gas path plate, and particularly the anti-of gas path plate crosses laminated structure.
Background technology
At present, the form that gas path plate on rolling stock more employing top gas path plate is bonding with bottom gas path plate, because gas circuit is complicated, narrow space in gas path plate, gas path plate is difficult to arrange pressure limiting device, and most pressure limiting device complex structure, comparatively complicated gas circuit is not suitable for installing conventional pressure limiting device, and in vehicle travel process, there is vibratory impulse frequently, be difficult to the stability ensureing pressure limiting device, so need the high and simple mechanism of a kind of reliability to meet the needs in market, reach the object of pressure limiting.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the problem that the utility model solves is: the pressure limiting device complex structure of gas path plate, poor stability.
For solving the problem, the technical scheme that the utility model is taked is as follows:
There is the anti-gas path plate crossing laminated structure, comprise gas path plate upper cover plate, gas path plate lower shoe; Described gas path plate upper cover plate covers on described gas path plate lower shoe; The transfer port matched is provided with between described gas path plate upper cover plate and gas path plate lower shoe; Described gas path plate upper cover plate is provided with pressure limiting passage; One end of described pressure limiting passage is communicated with transfer port, and the other end extends on the plate face of gas path plate upper cover plate; Pressure limiting sealing band is provided with in described pressure limiting passage; The path of described pressure limiting sealing band sealed pressure-limiting passage; Described pressure limiting sealing band is that elastomeric material is made.
Further, described pressure limiting passage comprises pressure limiting seal groove and pressure limiting air channel; Described pressure limiting seal groove and the end-to-end link of pressure limiting air channel; Described pressure limiting seal groove is located between gas path plate upper cover plate and gas path plate lower shoe; Described pressure limiting air channel is located in gas path plate upper cover plate; Described pressure limiting sealing band is located in pressure limiting seal groove; Described pressure limiting seal groove is communicated with transfer port.
Further, described pressure limiting seal groove is vertically connected with pressure limiting air channel.
Further, the upper surface of described pressure limiting sealing band is fixed on the upper medial surface of pressure limiting seal groove.
Further, the lower surface of described pressure limiting sealing band is fixed on the lower medial surface of pressure limiting seal groove.
Further, the rounded structure of described transfer port.
Further, described gas path plate upper cover plate is connected by adhesion agent with gas path plate lower shoe, and gas path plate upper cover plate and gas path plate lower shoe are fixed by screw.
The beneficial effects of the utility model
In the utility model, when gas path plate is ventilated, gas flows from transfer port, and when air pressure superpressure, gas push pressure limiting sealing band makes it be out of shape, and when pressure limiting sealing band is deformed to a certain degree, gas flows out from pressure limiting passage; When gas path plate internal pressure reduces to certain value, its airflow thrust reduces, and the deformation of pressure limiting sealing band recovers thus ensures that the state that gas path plate jolts in source of the gas superpressure and vibration still can ensure stable work.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model content is described in further detail.
embodiment 1
As shown in Figure 1, a kind of have the anti-gas path plate crossing laminated structure, comprises gas path plate upper cover plate 1, gas path plate lower shoe 6.Gas path plate upper cover plate 1 and the rectangular structure of gas path plate lower shoe 6 in the present embodiment.Gas path plate upper cover plate 1 to cover on gas path plate lower shoe 6.Gas path plate upper cover plate 1 is connected by adhesion agent with gas path plate lower shoe 6, and gas path plate upper cover plate 1 and gas path plate lower shoe 6 are fixed by screw again.Be provided with the transfer port 2 matched between gas path plate upper cover plate 1 and gas path plate lower shoe 6, in the present embodiment, transfer port 2 can preferred rounded structure further.Gas path plate upper cover plate 1 is provided with pressure limiting passage.One end of described pressure limiting passage is communicated with transfer port 2, and the other end extends on the plate face of gas path plate upper cover plate 1.Pressure limiting sealing band 3 is provided with in pressure limiting passage.The path of pressure limiting sealing band 3 sealed pressure-limiting passage.Pressure limiting sealing band 3 is made for elastomeric material, and what further illustrate be pressure limiting sealing band 3 is hyperelastic body, deformation can occur within the specific limits, and can restore to the original state rapidly.In the utility model, when gas path plate is ventilated, gas flows from transfer port 2, and when air pressure superpressure, gas push pressure limiting sealing band 3 makes it be out of shape, and when pressure limiting sealing band 3 is deformed to a certain degree, gas flows out from pressure limiting passage; When gas path plate internal pressure reduces to certain value, its airflow thrust reduces, and pressure limiting sealing bar shaped 3 recovers thus ensures that the state that gas path plate jolts in source of the gas superpressure and vibration still can ensure stable work.
Further preferably, pressure limiting passage comprises pressure limiting seal groove 4 and pressure limiting air channel 5.Pressure limiting seal groove 4 and pressure limiting air channel 5 end-to-end link.Pressure limiting seal groove 4 is located between gas path plate upper cover plate 1 and gas path plate lower shoe 6.Pressure limiting air channel 5 is located in gas path plate upper cover plate 1.Pressure limiting sealing band 3 is located in pressure limiting seal groove 4.Pressure limiting seal groove 4 is communicated with transfer port 2.Further preferably, pressure limiting seal groove 4 is vertically connected with pressure limiting air channel 5.Further preferably, in the present embodiment, the upper surface of pressure limiting sealing band 3 is fixed on the upper medial surface of pressure limiting seal groove 4.The lower surface of pressure limiting sealing band 3 and the lower medial surface of pressure limiting seal groove 4 are fitted but do not fix, when air pressure superpressure, there is deformation in pressure limiting sealing band 3 lower surface, thus cause the lower medial surface opening of pressure limiting sealing band 3 lower surface and pressure limiting seal groove 4, make gas flow to pressure limiting air channel 5 from opening part and discharge outside.
embodiment 2
The present embodiment is with reference to embodiment 1, and difference is that the lower surface of pressure limiting sealing band 3 is fixed on the lower medial surface of pressure limiting seal groove 4.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
