Abstract
The utility model discloses a high pressure and low pressure resistant Y-shaped sealing ring, which is in a Y-shaped structure. The sealing ring comprises a working surface part of a sealing body and non-working surface part of the sealing body, wherein the working surface part of the sealing body is provided with two or three oil storage grooves, and the non-working surface part of the sealing body is provided with three or four secondary lips. According to the utility model, the problems of non-sealing surface leakage and non wear resistance of sealing lips of the sealing ring in the using process are effectively solved, a good sealing effect can be achieved no matter in low pressure, intermediate pressure or high pressure condition, and the service life of the sealing ring can be prolonged.
Description
Technical field
The utility model relates to technical field of sealing technology, especially relates to oil hydraulic cylinder and uses seal ring.
Background technique
Of a great variety to present oil hydraulic cylinder, but can be divided into high, medium and low three kinds according to pressure rating, but some special oil hydraulic cylinder is in working order down, and three kinds of situation can occur simultaneously, but common Y shape circle is difficult to satisfy this operating mode.
Existing Y shape coil structures is following:
As shown in Figure 1, this seal ring under high speed to-and-fro motion (0.5m/s), unbalance loading situation and the pressurize situation, is prone to upset, causes the non-working surface sealing effect poor under high pressure conditions.
As shown in Figure 2, though this seal ring low pressure is effective, be in the long-term work of high pressure, owing to this body structure, extrude situation such as gap, pressure, can cause the seal lip wearing and tearing.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, and a kind of y-shaped ring of anti-the high low pressure is provided, and solves the rod seal leakage problem; Under low pressure, high-pressure situations, all can reach good sealing effect, can bear instantaneous pressure simultaneously; As the pair sealing, sealing effect is better.
A kind of y-shaped ring of anti-high low pressure of the utility model is to realize through such technological scheme:
A kind of y-shaped ring of anti-high low pressure the, its structure are the Y type, and said seal ring comprises seal working surface part and seal non-working surface part.
As preferably, described seal working surface partly has 2 to 3 road oil storage tanks, solves working state band oil problem, solves the problem of lack of lubrication simultaneously.
As preferably, described seal non-working surface partly is added with the secondary lip in 3 to 4 roads, can solve unbalance loading, the high pressure counter-rotating causes seal failure, pressurize situation leakage problem.
The utility model relate to a kind of y-shaped ring of anti-the high low pressure be applicable to axle with sealing or hole with sealing, seal is selected material different according to different working conditions, surpasses 16Mpa and adopts polyurethane material, Gao Kenai is to 40Mpa.
Compared with prior art, the advantage of the utility model is: when the unbalance loading situation occurring when serious, this seal ring can utilize itself the structural advantage of oneself under the static seal situation, solve low-pressure leak.Under high-pressure situations, the radial force of utilizing secondary lip again and being produced is paid effect with sticking, solves pressure transient, the counter-rotating that is caused, distortion etc.The utility model solved effectively seal ring in use the non-tight face leak and the not wear-resisting problem of seal lip, no matter under basic, normal, high pressure situation, all can reach good sealing effect, and can increase the service life.
Description of drawings
Through embodiment, the utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the common high Y shape circle such as non-of existing technology;
Fig. 2 is the structural representation of existing technology high Y shape circle such as common;
Fig. 3 is a kind of y-shaped ring of anti-high low pressure structural representation of the utility model;
1 is seal working surface part, and 2 is seal non-working surface part, and 3 is oil storage tank, and 4 is secondary lip.
Embodiment
In Fig. 1, a kind of y-shaped ring of anti-the high low pressure, its structure is the Y type, said seal ring comprises seal working surface part 1 and seal non-working surface part 2.Described seal working surface part 1 has 2 road oil storage tanks 3.Described seal non-working surface part 2 is added with the secondary lip 4 in 3 roads.
The seal ring working surface has oil storage tank, can solve oil film problem in the backhaul, can store sealing medium simultaneously; Thereby make sealing reach lubrication; Kill two birds with one stone, better solve the incipient scorch that piston rod band oil phenomenon and seal lip dry friction bring, thus prolongation seal ring working life.
The foregoing description; It is an instance of the utility model; Be not enforcement and the interest field that is used for limiting the utility model, all and the said same content of the utility model claim or the technological scheme that is equal to all should be included in the utility model protection domain.
Claims (3)
1. y-shaped ring of anti-the high low pressure, its structure is the Y type, it is characterized in that: said seal ring comprises seal working surface part and seal non-working surface part.
2. a kind of y-shaped ring of anti-high low pressure the according to claim 1 is characterized in that: described seal working surface partly has 2 to 3 road oil storage tanks.
3. a kind of y-shaped ring of anti-high low pressure the according to claim 1 is characterized in that: described seal non-working surface partly is added with the secondary lip in 3 to 4 roads.
