The following problems exist in the prior art:
1. the existing booster pipe special-shaped sealing element is difficult to assemble in the using process, because the 0-shaped sealing ring is sealed by depending on the compression amount of the sealing ring, if good sealing is required to be formed, large interference is needed, so that the assembling force is large and exceeds 100N;
2. the sealing performance of the existing pressure increasing pipe sealing element is gradually reduced under the action of high-pressure gas pressure in the using process, and as the pressure is increased, the force of the gas pressure acting on a 0-shaped ring is increased, and the force can extrude a sealing ring to develop towards the direction of separating from the sealing surface of a pressure increasing pipe assembly shaft, so that leakage is caused under the condition of high pressure.
Disclosure of Invention
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
a structure with a special-shaped sealing element in a booster pipe comprises a booster assembling pipe, a special-shaped sealing ring and a booster assembling shaft, wherein the booster assembling shaft is movably arranged in the booster assembling pipe, and the special-shaped sealing ring is arranged between the booster assembling pipe and the booster assembling shaft.
The utility model discloses technical scheme's further improvement lies in: the inner wall of the pressurizing assembly pipe is in sliding fit with the outer wall of the pressurizing pipe assembly shaft.
The utility model discloses technical scheme's further improvement lies in: and the inner wall of the supercharging assembly pipe is provided with a special-shaped sealing ring mounting groove, the special-shaped sealing ring is mounted in the special-shaped sealing ring mounting groove, and the special-shaped sealing ring is in sealing fit with the supercharging assembly pipe and the supercharging pipe assembly shaft.
The utility model discloses technical scheme's further improvement lies in: the outer wall of the pressurizing pipe assembling shaft is integrally provided with a guide table, one side of the guide table, which is positioned inside the pressurizing pipe, is provided with a first positioning slope, and the inside of the pressurizing pipe assembling shaft is provided with a second positioning slope corresponding to the first positioning slope.
The utility model discloses technical scheme's further improvement lies in: and one side of the special-shaped sealing ring, which is far away from the second positioning slope, is provided with a pressure-bearing groove.
Owing to adopted above-mentioned technical scheme, the utility model discloses relative prior art, the technological progress who gains is:
1. the utility model provides a have structure of heterotypic sealing member in booster pipe, because this heterotypic sealing member's sealed by the atmospheric pressure effect pressure seal, so the volume of compression can design very little when sealed design, that is exactly the interference volume can design very little for booster pipe assembly shaft power can be controlled at less scope when inserting, convenient assembly.
2. The utility model provides a have structure of heterotypic sealing member in booster pipe, because this heterotypic sealing member is compressed tightly sealed by the gas pressure effect, so under the high condition of pressure, sealing performance is more excellent, because pressure makes the sealing member receive the effect of gas pressure power bigger greatly to the sealing area who pastes booster pipe assembly axle that more can be inseparable forms better sealedly.
