Description
Technical field
This utility model belongs to sealing ring technical field, is specifically related to a kind of hydraulic sealing ring.
Background technology
The leakage of hydraulic oil is always a thorny problem on hydraulic, and it not only affects service behaviour and the production efficiency of hydraulic, but also pollutes production environment and waste resource etc..Putting into practice knowhow to show, the effective approach solving hydraulic hydraulic fluid leak is exactly the sealing ring selecting sealing property excellent.By selecting suitable material and the hydraulic sealing ring of suitable configurations form, and take corresponding safeguard procedures, the sealing property of conventional hydraulic sealing ring, the economic benefit of enterprise can be improved to greatest extent.
The current sealing ring using more high pressure resistant and low pressure in Hydraulic Field is all that the sealing ring of this structure often purchase cost is higher based on the structure of Cu-base composites bound rubber circle, and mounting process is more complicated.Therefore it provides a kind of with low cost, easy for installation and that sealing property is excellent sealing ring has become the technical problem that manufacturing enterprise is urgently to be resolved hurrily.
Utility model content
In order to make up the deficiencies in the prior art, this utility model provides a kind of with low cost, easy for installation and that sealing property is excellent hydraulic sealing ring.
Technical scheme is as follows:
Described hydraulic sealing ring, including polyurethane sealing ring, it is characterized in that described polyurethane sealing ring inwall is provided with the first groove, 0 shape circle it is embedded in the first described groove, described polyurethane seal ring outer wall is provided with annular projection, described polyurethane sealing ring at least side end face outer rim is provided with the second groove, is provided with back-up ring in the second described groove.
Described hydraulic sealing ring, it is characterised in that described polyurethane sealing ring both sides end face outer rim is designed with the second groove, is provided with back-up ring in described second groove.
Described hydraulic sealing ring, it is characterised in that the first described groove is arranged at polyurethane sealing ring inwall centre position, described annular projection is arranged at polyurethane seal ring outer wall centre position.
Described hydraulic sealing ring, it is characterised in that described back-up ring is nylon back-up ring.
Described hydraulic sealing ring, it is characterised in that the first described channel section is circular arc or rectangle.
Use structure of the present utility model, provide the benefit that compared to existing technology: this utility model main body is polyurethane sealing ring, polyurethane sealing ring offers the groove coordinated with 0 type circle and nylon back-up ring, this structure and material low cost, easy for installation；Use O can effectively carry out static seal, add polyurethane sealing ring and carry out movable sealing, strengthen sealing property, even if nylon back-up ring can ensure that hydraulic sealing ring also will not deform under conditions of high pressure, as usual use.

Detailed description of the invention
With embodiment, application of the present utility model is illustrated below in conjunction with the accompanying drawings.
Embodiment 1
It Fig. 1 is the one side of this enforcement hydraulic sealing ring with back-up ring 3, including polyurethane sealing ring 1 as shown in Figure 2, described polyurethane sealing ring 1 inwall centre position is provided with the first groove 10, the first described groove 10 cross section is circular arc, being embedded 0 shape circle 2 in first groove 10, polyurethane sealing ring 1 outer wall centre position is provided with annular projection 11, and polyurethane sealing ring 1 one side end face outer rim is provided with the second groove 12, being equipped with back-up ring 3 in described second groove 12, back-up ring 3 preferably selects nylon back-up ring.First groove 10 cross section can also be rectangle.
Embodiment 2
It Fig. 3 is the bilateral of the present embodiment hydraulic sealing ring with back-up ring 3, the polyurethane sealing ring 1 both sides end face outer rim that difference with embodiment 1 maximum is in the present embodiment is designed with the second groove 12, being equipped with back-up ring 3 in corresponding both sides the second groove 12, remaining is local completely the same with embodiment 1.
Owing to the use principle of two kinds of embodiments is essentially identical, so illustrating in the lump herein.During use, hydraulic sealing ring is loaded in the seal groove of piston 4, then seal after piston 4 is loaded oil cylinder 5.It is to seal by O 2 inside hydraulic sealing ring, is to seal by polyurethane sealing ring 1 outside hydraulic sealing ring.Hydraulic sealing ring, when there is elevated pressures the side being provided with back-up ring 3, due to the insufficient strength of polyurethane sealing ring 1 material, is easily deformed and comes off, and back-up ring 3 has the effect of fixing support, makes polyurethane sealing ring 1 be not easy deformation and comes off.One side has the hydraulic sealing ring of back-up ring 3 and is to ensure that the high-pressure tightness of one side, and bilateral has the hydraulic sealing ring of back-up ring 3 and can effectively ensure the high-pressure tightness of bilateral.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or use similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
