Description
Technical Field
The utility model relates to a sealing washer technical field especially relates to a well low-pressure seal circle of OR compensation function is joined in marriage in shaft hole.
Background
The sealing ring is a fitting for sealing, is widely applied to various mechanical seals and pipeline seals, cannot be simultaneously applied to medium-pressure and low-pressure environments at present, is poor in adaptability and is inconvenient to popularize.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving among the prior art present sealing washer can not be suitable for simultaneously with middling pressure and low pressure environment in, adaptability is poor, the not facilitate promotion problem, and the well low-pressure sealing washer of OR compensation function is joined in marriage in a shaft hole that provides.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a well low-voltage seal circle of OR compensation function is joined in marriage in shaft hole, includes the sealing washer, one side fixedly connected with seal lip of sealing washer, seal lip is the annular setting, the seal groove has been seted up to one side that the seal lip kept away from the sealing washer, the tank bottom of seal groove has been seted up and has been supported the groove, it is provided with the lock ring to support the inslot, the cross-section that supports the groove is circular setting, lock ring and support groove phase-match.
Preferably, the sealing lip is arranged in a T shape.
Preferably, the end of the sealing lip, which is far away from the sealing ring, is chamfered by 40 degrees.
Preferably, the sealing ring, the sealing lip and the support ring are all made of polyurethane.
Preferably, the thickness of the sealing ring is 10 mm.
Compared with the prior art, the utility model provides a well low-pressure seal circle of OR compensation function is joined in marriage in shaft hole possesses following beneficial effect:
this well low-pressure sealing washer of OR compensation function is joined in marriage in shaft hole can rely on liquid pressure to increase the leakproofness when the middling pressure, relies on the holding ring to increase the leakproofness when the low pressure, and strong adaptability is convenient for promote, and the leakproofness is good, simple structure, and economic nature is good.
The part that does not relate to in the device all is the same with prior art or can adopt prior art to realize, the utility model discloses can rely on liquid pressure to increase the leakproofness when the middling pressure, rely on the lock ring to increase the leakproofness when the low pressure, strong adaptability, the facilitate promotion, the leakproofness is good, simple structure, and economic nature is good.
Drawings
Fig. 1 is a schematic structural view of a middle-low pressure seal ring with an OR compensation function in a shaft hole according to the present invention;
fig. 2 is a side view of the middle-low pressure seal ring with the shaft hole matching OR compensation function provided by the present invention.
In the figure: 1 sealing ring, 2 sealing lips, 3 sealing grooves and 4 support rings.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a middle-low pressure seal ring with an OR compensation function matched with a shaft hole comprises a seal ring 1, one side of the seal ring 1 is fixedly connected with a seal lip 2, the seal lip 2 is arranged in an annular shape, one side of the seal lip 2, which is far away from the seal ring 1, is provided with a seal groove 3, the bottom of the seal groove 3 is provided with a support groove, a support ring 4 is arranged in the support groove, the cross section of the support groove is arranged in a circular shape, the support ring 4 is matched with the support groove, when the water pressure is high, water enters the seal groove 3, the seal lip 2 is pressed by the water pressure to be opened, the seal lip 2 is abutted against the inner wall of a pipeline, the higher the water pressure is, the better the sealing property is obtained, when the water pressure is low, the seal lip 2 is abutted against the inner wall of the pipeline through the elasticity of the support ring 4, simple structure and good economical efficiency.
The sealing lip 2 is arranged in a T shape, and the sealing effect is better.
The end of the sealing lip 2, which is far away from the sealing ring 1, is provided with a chamfer of 40 degrees, and the sealing effect is good.
The sealing ring 1, the sealing lip 2 and the support ring 4 are made of polyurethane, so that the wear resistance is better, and the service life is long.
The thickness of sealing washer 1 is 10mm, and elasticity is more sufficient, and the leakproofness is good.
The utility model discloses in, when water pressure is higher, water gets into seal groove 3, water pressure oppression seal lip 2 opens, seal lip 2 offsets with the pipe inner wall, water pressure is big more, the leakproofness is better, when water pressure is lower, elasticity through lock ring 4 offsets seal lip 2 and pipe inner wall, can be when the middling pressure, rely on liquid pressure to increase the leakproofness, rely on lock ring 4 to increase the leakproofness when the low pressure, strong adaptability, and the facilitate promotion, the leakproofness is good, simple structure, and economic nature is good.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
