Abstract
The technology is a bidirectional V-shaped seal, which is a dynamic seal or a static seal aiming at the pressure on both sides, is suitable for a more reliable combined seal form with different grades of pressure, and the combined seal has better sealing effect under the working conditions of high pressure impact and low pressure.
Description
The technical field is as follows:
the technology belongs to the technical field of sealing, and particularly relates to a bidirectional V-shaped seal.
Background art:
in the technical field of sealing elements, the sealing element has high pressure impact resistance and strong extrusion resistance, and under the working condition of ultralow pressure, the sealing element with good sealing effect is few, so that the sealing element is difficult to adapt to the changes of high, medium and low pressure and different grades of pressure simultaneously, and the sealing effect is not ideal under the working conditions of pressure change and dynamic load.
The invention content is as follows:
the purpose of the technology is to overcome the defects of the prior art and provide a bidirectional V-shaped seal which is suitable for different pressure changes and has good sealing effect under high pressure, medium pressure and low pressure.
In order to achieve the purpose, the technology consists of a left baffle ring, a left V ring, a left middle V ring, a left bottom V ring, a support ring, a right bottom V ring, a right middle V ring, a right V ring and a right baffle ring, wherein the left V ring and the right V ring are made of high-hardness polyurethane; the left and right sides of the supporting ring are respectively provided with a bottom V-shaped ring, a middle V-shaped ring, a first V-shaped ring and a baffle ring, the middles of the left and right first V-shaped rings are respectively provided with a U-shaped groove, and the left and right baffle rings are respectively provided with a U-shaped convex groove; two end faces of the supporting ring are provided with concave V-shaped grooves, and the V-shaped opening angles are both 60 degrees; the first V ring, the middle V ring and the bottom V ring are overlapped together, and a left retaining ring and a right retaining ring are respectively arranged at two ends of the first V ring, the middle V ring and the bottom V ring.
Compared with the prior art, the beneficial effects of a two-way V-shaped seal are: from the motion state, the combined seal is suitable for dynamic seal and static seal; from the pressure range, the pressure-bearing sealing device is suitable for the pressure changes of high, medium and low and different grades, and has good sealing effect under the working conditions of pressure change and dynamic load.

in the figure: the left gear ring 1, the left head V ring 2, the left middle V ring 3, the left bottom V ring 4, the supporting ring 5, the right bottom V ring 6, the right middle V ring 7, the right head V ring 8 and the right gear ring 9.
Detailed Description
The following description of the present technology with reference to the drawings and examples shows a bidirectional V-seal, which is operated as follows:
firstly, when in use, the installation groove is an open groove, the left baffle ring 1 is firstly placed into the groove, and one end with a U-shaped convex groove faces outwards; step two, sequentially stacking a left first V-shaped ring 2, a left middle V-shaped ring 3 and a left bottom V-shaped ring 4 in a V shape, and then placing a supporting ring 5 in the groove; thirdly, because the two end surfaces of the supporting ring 5 are respectively provided with a concave V-shaped groove, a right bottom V-shaped ring 6, a right middle V-shaped ring 7 and a right head V-shaped ring 8 are sequentially superposed in a V-shaped direction, and finally a right baffle ring 9 is placed into the groove, and one end with a U-shaped convex groove faces inwards; and step four, sealing the open groove.
This technique two-way V-arrangement is sealed, its structural feature is: which comprises the following steps: the left V-shaped ring 2 and the right V-shaped ring 8 are made of high-hardness polyurethane; the left middle V-shaped ring 3 and the right middle V-shaped ring 7 are made of nitrile rubber, the left bottom V-shaped ring 4 and the right bottom V-shaped ring 6 are made of polyurethane, and the left baffle ring 1, the right baffle ring 9 and the support ring 5 are made of high-hardness plastic; u-shaped grooves are formed in the middle of the left V-shaped ring 2 and the right V-shaped ring 8; the left baffle ring 1 and the right baffle ring 9 are both provided with U-shaped convex grooves; the left middle V-shaped ring 3, the right middle V-shaped ring 7, the left bottom V-shaped ring 4 and the right bottom V-shaped ring 6 are both in a double-lip shape, and the cross sections of the two V-shaped rings form a V-shaped included angle; the two end faces of the supporting ring 5 are provided with concave V-shaped grooves, and the V-shaped opening angles are both 60 degrees.
