Abstract

The utility model discloses a mould is made to oil gas pipeline leather cup screw sealing washer, including the leather cup mould, the leather cup mould on be equipped with the interior zhou duanwei O type sealing washer tongue of bolt through -hole and the concave type seal groove of leather cup mould screw, the concave type seal groove of leather cup mould screw. Implement the technical scheme of the utility model, following beneficial effect has: mould is made to oil gas pipeline leather cup screw sealing washer, the leather cup screw sealing washer that produces has been solved the shutoff leather cup and has been got into the problem that bolt position oil gas cluster leaks behind the pipeline, improves the sealed effect of pipeline, adopts this kind of device to shorten the engineering time in building site greatly in addition, improves work efficiency.

Description

Oil and gas pipes leather cup screw sealing ring mfg. moulding die
Technical field
The utility model relates to a kind of oil and gas pipes plugging device mfg. moulding die, is specifically related to a kind of oil and gas pipes leather cup screw sealing ring mfg. moulding die.
Background technology
Along with the development in city, continue to increase to the demand of oil gas.At present, petroleum chemical industry adopts pipeline to carry out the fuel such as transfer oil, natural gas, liquefied gas usually.Under conveyance conduit is in high pressure conditions for a long time, adds the corrosion to pipeline such as oil, natural gas, easily leak.Once leak, need to rush to repair in time, need during repairing to carry out shutoff to pipeline.But the plugging leather cup adopted at present is the rear fender and the rubber cup that are passed block head by high-strength bolt, be fixed on block head front pressuring plate, pass through plugging device, under the state of sealing, be placed in pipeline, when leather cup is completely perpendicular to inner-walls of duct, after discharging the pipeline section pressure by shutoff, define the individual event pressure of pipeline internal medium to leather cup, leather cup lip edge position spreading can be reached the object of pipe plugging.But this plugging device always has certain micro-leakage phenomenon, the especially shutoff of gas pipeline.Learn through detection, find micro-leakage not in the lip edge position of leather cup, and leak in the bolt part bit string of turnbuckle, the string that how could solve between screw rod and leather cup screw leaks, need to produce this leather cup mould, and then produce this leather cup, solve the problem that leather cup string leaks.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of oil and gas pipes leather cup screw sealing ring mfg. moulding die, and the leather cup that it produces can solve micro-leakage phenomenon of bolt hole and bolt bearing, improves the sealing effectiveness of pipeline.
In order to solve the problem, the utility model is by the following technical solutions: a kind of oil and gas pipes leather cup screw sealing ring mfg. moulding die, comprise leather cup mould, described leather cup mould is provided with bolt hole and leather cup mould screw matrix seal groove, and the inner circumferential end of leather cup mould screw matrix seal groove is O RunddichtringO tongue.
Fluid injection of being precoated by rubber is expelled in leather cup mould, and rear taking-up to be formed can obtain leather cup bolt hole convex sealing ring, and leather cup bolt hole convex sealing ring has O type circle tongue and leather cup bolt hole.
Implement the technical solution of the utility model, there is following beneficial effect: oil and gas pipes leather cup screw sealing ring mfg. moulding die described in the utility model, the leather cup screw sealing ring produced, solve plugging leather cup and enter the problem that bolt position oil gas string leaks after pipeline, improve the sealing effectiveness of pipeline, and adopt this device to substantially reduce the engineering time in building site, increase work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Fig. 1 is the structural representation of leather cup mould.
Fig. 2 is the structural representation of leather cup workpiece.
1-O type circle tongue; 2-leather cup bolt hole; 3-leather cup mould; 4-leather cup mould screw matrix seal groove; 5-bolt hole; 6-O RunddichtringO tongue.
Detailed description of the invention
Below with reference to the accompanying drawings 1 and 2 and in conjunction with the embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of oil and gas pipes leather cup screw sealing ring mfg. moulding die, comprise leather cup mould 3, described leather cup mould 3 is provided with bolt hole 5 and leather cup mould screw matrix seal groove 4, and the inner circumferential end of leather cup mould screw matrix seal groove 4 is O RunddichtringO tongue 6.
Fluid injection of being precoated by rubber is expelled in leather cup mould 3, and rear taking-up to be formed can obtain leather cup bolt hole convex sealing ring, leather cup bolt hole convex sealing ring has O type circle tongue 1 and leather cup bolt hole 2.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any people being familiar with this technology is in the technical scope disclosed by the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
