Abstract
The invention discloses a seal ring. The seal ring (1) has an E-shaped cross section. Compared with prior art, the inventive seal ring has large bearing capacity and good sealing property, can be used repeatedly, and can greatly reduce the use cost for enterprises. The invention is used in the field of periodic axial deformation of a sealed groove, can ensure the deformation of a large-sized sealed groove with high-voltage pulses, and has good rebound elasticity and reusability.
Description
Technical field
The present invention relates to a kind of seal ring.
Background technique
O shape rubber seal commonly used because its bearing capacity and sealability are relatively poor, is difficult to satisfy the demands under some special operation condition.And common O shape rubber seal is disposable often, can not reuse, and causes very big waste.
Summary of the invention
The objective of the invention is to, provide that a kind of bearing capacity is strong, good airproof performance and can reusable seal ring, thereby overcome the deficiencies in the prior art.
The present invention constitutes like this: a kind of seal ring.The sectional shape of sealing circle is an E shape.
In the above-mentioned seal ring, the material of described seal ring is stainless steel or refractory alloy.
Compared with prior art, bearing capacity of the present invention is bigger than common O shape rubber seal, because O shape rubber seal is when bearing big pressure, and can be because the resiliently deformable of rubber, make seal failure, but the E shape seal ring of rigid material has then overcome this problem.Because the present invention turns to the purpose that reaches sealing by its arc sealing surface bending, therefore, has stronger sealability.And as long as the axial free height of seal ring is higher than the seal groove axial height at least 005 of use " (inch), its seal ring just can be reused, and greatly reduces the user cost of enterprise, has avoided waste.The present invention is applicable to the periodically occasion of axial deformation of seal groove, mainly is in order to adapt to high-pressure pulsating and big seal groove distortion, and product has good resilience and repeat performance.The selection of material of E shape seal ring is generally stainless steel or refractory alloy, selects different surface treatment modes according to user mode.Divide inboard pressure-bearing type and the outside pressure-bearing type of mainly containing by purposes.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Embodiments of the invention: as shown in Figure 1, seal ring 1 adopts stainless steel or high-temperature alloy material to make, and its sectional shape is E shape (as shown in Figure 2).Typical applied environment of the present invention and mounting point have following several: 1, turbine unit room: pressure 400psi, 1100 of temperature, the axial thermal distortion of seal groove, 060 " gas seal and the fixedly sealing of axial clearance; 2, liquid seal high-temp liquid: fluctuation pressure 3000psi, 500 of temperature, seal groove axial deformation, 003 "; 3, fuel nozzle: the gas seal that pressure 50psi, temperature are 700, minor diameter sealing, the sealing that axial clearance is fixing; The gas seal of 4, gas-turbine: diameter 60 ", unidirectional rotation, pressure 50psi, 900 of temperature, seal groove axial deformation, 030 "; Two 180 arcuate structure spare sealings etc.
Claims (2)
1. seal ring, it is characterized in that: the sectional shape of sealing circle (1) is an E shape.
2. seal ring according to claim 1 is characterized in that: the material of described seal ring (1) is stainless steel or refractory alloy.
