Abstract

A carbon-silicon sealing element is provided, which mainly solves the problem of poor sealing effect and short service life of existing sealing elements. The sealing element is characterized in: an annular groove (2) with semi-circular cross section is arranged on a side end face of a sealing body (1), a O-ring (3) is arranged in the groove (2), and both the sealing body (1) and the O-ring (3) are made of a carbon, silicon, and metal composite material. The carbon-silicon sealing element has advantages including good sealing effect, long service life, and oil, acid, temperature, abrasion, and tensile resistance.

Description

Carbon silicon Sealing

Technical field:

The utility model relates in the oil recovery field, oil field used Sealing on the pumping unit, belongs to carbon silicon Sealing.

Background technique:

Present Sealing used on pumping unit, simple in structure, sealing effect is poor, and using just had the seepage phenomenon in 3-7 days, particularly between 25 ℃-35 ℃ of 5,6,7,8 month temperatures, oil sealing is torn seriously, cause the breakthrough of local area slight crack, temperature is at 0 ℃--and 35 ℃ of this phenomenons are more outstanding, make seepage serious, must stop production and keep in repair, influence produced quantity; And existing sealing member material is to be raw material with Dingqing's glue, natural gum and reclaimed rubber, more than three kinds of synthetic Sealing oil resistants of producing of raw material, acidproof, heatproof and wear-resistant, tensility is poor, to make oil sealing working life short, sealing effect is poor.

The utility model content:

In order to overcome short deficiency of existing Sealing sealing effect difference and working life, the utility model provides a kind of carbon silicon Sealing, and this carbon silicon Sealing good sealing effect, long service life have oil resistant, acidproof, heatproof and characteristics wear-resistant, tension.

The technical solution of the utility model is: this carbon silicon Sealing comprises seal, and having the cross section on the side end face of seal is semicircular annular groove, and groove is built-in with " O " RunddichtringO.

The material of above-mentioned seal and " O " RunddichtringO is the synthetic material of carbon, silica gel and metallic material.

The utlity model has following beneficial effect: because to take such scheme, carbon silicon seal durability is 6 months to 1 year, non-leakage, indeformable, do not tear, good sealing effect; The synthetic material of carbon element, silica gel and metallic material has oil resistant, acidproof, heatproof and advantage wear-resistant, tension, and long service life uses this carbon silicon Sealing to reduce cost of production, has reduced the workover workload, has improved manufacturing efficiency

Description of drawings:

Fig. 1 is a structure sectional view of the present utility model.

1-seal among the figure, 2-groove, 3-seal ring.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in FIG., this carbon silicon Sealing comprises seal 1, and having the cross section on the side end face of seal 1 is semicircular annular groove 2, and groove 2 is built-in with " o " RunddichtringO 3, good sealing effect, ne-leakage; The material of seal 1 and " o " RunddichtringO 3 is the synthetic material of carbon element, silica gel and metallic material, and carbon element is a kind of wear-resisting, the material of heatproof, oil resistant, acid resistant alkali, and have and touch the characteristics of splashing automatically and rising behind the oil, reach and touch oily self-sealing requirement; Silica gel is a kind of heatproof, oil resistant, acid resistant alkali and crackless material; Metallic material is novel high-tech metallic material, and it is wear-resistant, pull resistance is strong, and friction stretching and the damage that causes of high temperature in use has the repairing effect to oil sealing; Sealing by the synthetic material of above three kinds of materials comprises pumping unit packing, packing element, self-sealing core, oil sealing etc., and this carbon silicon MP material seal is effective, long service life.

This shows, use this carbon silicon Sealing to reduce the workover workload, improved manufacturing efficiency, reduced cost of production.

Claims

1, a kind of carbon silicon Sealing comprises seal (1), it is characterized in that: having the cross section on the side end face of seal (1) is semicircular annular groove (2), and groove (2) is built-in with " O " RunddichtringO (3).

2, carbon silicon Sealing according to claim 1 is characterized in that: the material of seal (1) and " O " RunddichtringO (3) is the synthetic material of carbon element, silica gel and metallic material.
