Abstract
The utility model discloses a kind of seal ring being applicable to fuel evaporation mensuration confined chamber door, described seal ring is closed ring structure; The cavity be provided with for inflating is had in described seal ring; Described seal ring comprises inner side, outside, upside, downside, described seal ring is inner side towards the side at seal ring center, and described inner side is plane, and the side relative with described inner side is outside, the concave surface of described outside for caving inward, described upside and downside are plane; Described inner side is provided with a suction port; Described seal ring is silicone rubber material.The seal ring of model utility adopts silicone rubber material, impermeable and hydrocarbon release, also not with hydrocarbon, sulphide generation chemical reaction, long service life, ensures the accuracy of sealed mode method measurement result simultaneously; Employing concave surface contacts, and after inflation, outstanding deformation reaches sealing effect, and compared with contacting with the face of prior art, long service life, is not easy the phenomenon that leaks air.
Description
Technical field
The utility model relates to a kind of seal ring, and especially a kind of fuel evaporation measures the seal ring of confined chamber door.
Background technique
Confined chamber method is a kind of method of motorcycle fuel evaporation emissions measurement general in the world.During experiment, tested vehicle is placed in the good confined chamber of tightness, carries out associative operation according to standard, finally detect HC concentration in confined chamber by HC ANALYZER, calculate the HC quality of duration of test discharge.This method requires that confined chamber has very high sealing, and seal arrangement is impermeable and hydrocarbon release, also not with hydrocarbon, sulphide generation chemical reaction.
At present, in some sealing girths longer (several meters to hundreds of rice), sealing out-of-shape (curve or straight line) occasion, gas-flow closure can be used.This seal ring utilizes the flexible nature of rubber itself, is hidden in groove during normality, and during inflation, curve deformation occurs, intermediate portion outwards bulges, and with another sealing surface close contact, reaches sealing.This sealing means effectively can overcome the skimble-scamble situation of seal clearance, makes sealing not be subject to the impact of processing length and assembly precision, and also has the advantage of long service life, convenient disassembly and minimizing installation procedure.
Traditional gas-flow closure circle adopts face contact type, but in actual applications, works because rubber is in the environment of High Temperature High Pressure or low-temp low-pressure for a long time, and for several times, rubber elasticity reduces, and the phenomenon such as leak air, and sealing does not reach effect.
Model utility content
In order to overcome the problems referred to above, the purpose of this utility model is, there is provided a kind of be applicable to fuel evaporation measure confined chamber door, the seal ring of durable, impermeable and hydrocarbon release, also not with hydrocarbon, sulphide generation chemical reaction, ensure the sealing of confined chamber, and there is durability, long service life.
The technological scheme that the utility model is adopted for achieving the above object is:
Be applicable to the seal ring that fuel evaporation measures confined chamber door, it is characterized in that: described seal ring is closed ring structure; The cavity be provided with for inflating is had in described seal ring; Described seal ring comprises inner side, outside, upside, downside, described seal ring is inner side towards the side at seal ring center, and described inner side is plane, and the side relative with described inner side is outside, the concave surface of described outside for caving inward, described upside and downside are plane; Described inner side is provided with a suction port; Described seal ring is silicone rubber material.
The installation before use of the utility model seal ring, is placed in the rectangular recess of confined chamber door by seal ring, the concave surface of seal ring is outside, is connected by the suction port on seal ring by connecing soon with pressurized air.
During use, being closed to put in place by confined chamber door needs the position of inflation, and control valve is opened, pressurized air enters in the cavity of gas-flow closure circle, and cavity internal pressure increases, and the sunk part of seal ring outwards expands, form circular arc, contact with another sealing surface tight interference, implement sealing.
After use terminates, before confined chamber door is opened, need first to exit, control valve is opened, and the pressurized air in cavity is discharged into the atmosphere.
the beneficial effect of model utility:
1, seal ring adopts silicone rubber material, impermeable and hydrocarbon release, also not with hydrocarbon, sulphide generation chemical reaction, long service life, ensures the accuracy of sealed mode method measurement result simultaneously;
2, adopt concave surface contact, after inflation, outstanding deformation reaches sealing effect, and compared with contacting with the face of prior art, long service life, is not easy the phenomenon that leaks air.

Embodiment
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of seal ring being applicable to fuel evaporation mensuration confined chamber door, seal ring is closed ring structure; The cavity 1 be provided with for inflating is had in seal ring; Seal ring comprises inner side 2, outside 3, upside 4, downside 5, and seal ring is inner side 2 towards the side at seal ring center, and inner side 2 is plane, and the side relative with inner side 2 is outside 3, the concave surface of outside 3 for caving inward, and upside 4 and downside 5 are plane; Inner side is provided with a suction port 6; Seal ring is silicone rubber material.
The installation before use of the utility model seal ring, is placed in the rectangular recess of confined chamber door by seal ring, the concave surface of seal ring is outside, is connected by the suction port on seal ring by connecing soon with pressurized air.
As shown in Figure 4, Figure 5, during use, confined chamber door 7 is closed to put in place and needs the position of inflation, control valve is opened, and pressurized air enters in the cavity of gas-flow closure circle, and cavity internal pressure increases, the sunk part of seal ring outwards expands, form circular arc, contact with another sealing surface tight interference, implement sealing.
After use terminates, before confined chamber door is opened, need first to exit, control valve is opened, and the pressurized air in cavity is discharged into the atmosphere.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
