Description

Technical Field

[0001] This utility model belongs to the technical field of anti-overflow splitter housing sealing ring, specifically relating to an anti-overflow splitter housing sealing ring. Background Technology

[0002] The overflow prevention separator housing sealing ring is a key component installed in relevant parts of the separator housing. It is generally made of oil-resistant, wear-resistant, and highly elastic materials such as rubber and fluororubber. When the separator is working, when hydraulic oil enters the inner side of the ring, it will deform under hydraulic pressure and tightly fit against the inner wall of the housing to form a reliable sealing structure. This effectively prevents high-pressure fluids, silt, and other substances in the well from overflowing from the housing gaps to the outside of the separator, ensuring the normal and stable operation of the separator and avoiding safety accidents and equipment damage caused by leakage.

[0003] When the overflow prevention diverter housing sealing ring is in use, the prolonged friction between the sealing ring and external equipment will slow down the service life of the sealing ring. Therefore, the market needs a new device to solve the current problem. Utility Model Content

[0004] The purpose of this utility model is to provide an overflow-proof separator housing sealing ring to solve the problem that the overflow-proof separator housing sealing ring mentioned in the background art suffers from prolonged friction between the sealing ring and external equipment during use, which slows down the service life of the sealing ring. Therefore, the market needs a new device to solve the current problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing ring for a diverter housing to prevent overflow, comprising an outer protective layer of the sealing ring, a groove A provided at the upper end of the outer protective layer of the sealing ring, and a nanofiber layer installed at the upper end of the outer protective layer of the sealing ring through the groove A, wherein the nanofiber layer inserts a protruding buckle fixed at the lower end into the groove A, a groove B provided at the outer wall of the outer protective layer of the sealing ring, an oil storage cavity engaged at the inner side of the groove B, and multiple micropores distributed at the outer wall of the oil storage cavity, wherein lubricating oil is added to the inner part of the oil storage cavity through an oil injection hole at the front end, and a plug is inserted and installed at the front end of the oil injection hole.

[0006] Preferably, the outer structure of the outer protective layer of the sealing ring is provided with a reinforcing skeleton layer, which is made of stainless steel wire woven into a mesh structure to enhance the strength of the ring.

[0007] Preferably, the main sealing layer is located at the middle position inside the outer protective layer of the sealing ring, and the main sealing layer is made of rubber material.

[0008] Preferably, the innermost layer of the outer protective layer of the sealing ring is configured as an inner support ring. The inner support ring is made of hard plastic and is circular in shape to maintain the stability of the ring shape and prevent deformation.

[0009] Preferably, the outer protective layer of the sealing ring is made of a highly wear-resistant rubber material, which wraps the sealing ring on the inner side to protect the internal structure from external wear.

[0010] Preferably, the outer and inner diameters of the nanofiber layer are the same as those of the outer protective layer of the sealing ring, and the nanofiber layer inserts the protruding buckle into the inner position of the slot A, so that the nanofiber layer is installed at the upper end of the outer protective layer of the sealing ring.

[0011] Preferably, the oil storage cavity is engaged with the inner side of the slot B, and lubricating oil is added to the inner position of the oil storage cavity through the oil injection hole.

[0012] Preferably, the micropores allow lubricating oil from inside the oil reservoir to slowly permeate to the external location.

[0024] The utility model provides, for example Figure 1-4 The diagram shows a sealing ring for a diverter housing to prevent overflow. It includes an outer protective layer 1, with a groove A7 at the upper end of the outer protective layer 1. A nanofiber layer 2 is installed at the upper end of the outer protective layer 1 via the groove A7. The nanofiber layer 2 inserts a protruding buckle 9 fixed at the lower end into the groove A7. A groove B8 is provided on the outer wall of the outer protective layer 1, with an oil reservoir 3 engaged on the inner side of the groove B8. Multiple micropores 4 are distributed on the outer wall of the oil reservoir 3. Lubricating oil is added to the oil reservoir 3 through an oil injection hole 5 at its front end. A plug 6 is inserted into the front end of the oil injection hole 5.

[0025] During the assembly stage of the distributor, the housing sealing ring is precisely installed in a specific position to ensure that it fits tightly and is well aligned with the various components of the distributor housing. When drilling operations begin and the sealing function of the distributor needs to be activated, hydraulic oil is delivered to the inner side of the sealing ring. The injection of hydraulic oil will cause the sealing ring to expand and deform, making it fit tightly against the inner wall of the distributor housing, thereby forming an effective sealing ring.

[0026] like Figure 1 and Figure 2 As shown, the outer structure of the outer protective layer 1 of the sealing ring is provided with a reinforcing skeleton layer 10. The reinforcing skeleton layer 10 is made of stainless steel wire woven into a mesh structure, which can enhance the strength of the ring body. The main sealing layer 11 is set at the middle position inside the outer protective layer 1 of the sealing ring. The main sealing layer 11 is made of rubber material. The innermost structure inside the outer protective layer 1 of the sealing ring is set as an inner support ring 12. The inner support ring 12 is made of hard plastic and is circular in shape to keep the ring body stable and non-deformed. The outer protective layer 1 of the sealing ring is made of high wear-resistant rubber. The material wraps the sealing ring on the inside to protect the internal structure from external wear. The outer and inner diameters of the nanofiber layer 2 are the same as those of the outer protective layer 1 of the sealing ring. The nanofiber layer 2 inserts the protruding buckle 9 into the inside of the slot A7, so that the nanofiber layer 2 is installed at the upper end of the outer protective layer 1 of the sealing ring. The oil storage cavity 3 is engaged with the inside of the slot B8. The oil storage cavity 3 adds lubricating oil to the inside through the oil injection hole 5. The micropores 4 slowly allow the lubricating oil in the inside of the oil storage cavity 3 to penetrate to the outside.

[0027] Lubricating oil is added to the inside of the oil reservoir 3 through the oil injection hole 5. Multiple micropores 4 are distributed on the outer wall of the oil reservoir 3. The lubricating oil inside the oil reservoir 3 slowly seeps out through the micropores 4, forming a lubricating film on the sealing surface, reducing the coefficient of friction, reducing wear, and thus extending the service life of the sealing ring.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
