Abstract
The utility model discloses an oil gas pipeline leather cup screw sealing washer device, including shutoff leather cup, shutoff head, wherein be equipped with the screw on the sealed face of shutoff leather cup, in the facial position in the outer end of screw, be equipped with bellied O type sealing washer, shutoff head is including preceding clamp plate, rear fender, bolt, nut, and the bolt passes through the nut between with fixed clamp plate in the front of shutoff leather cup and rear fender. Oil gas pipeline leather cup screw sealing washer device, solved the problem that the shutoff leather cup got into bolt position oil gas microleakage behind the pipeline, improve the sealed effect of pipeline, adopt this kind of device to have shortened the engineering time in building site greatly in addition, improve work efficiency.
Description
Technical field
The utility model relates to a kind of oil and gas pipes blocking device, is specifically related to a kind of oil and gas pipes leather cup screw gasket set.
Background technique
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, rock gas, liquid gas usually.Under conveyance conduit is in high pressure conditions for a long time, adds the corrosion to pipeline such as oil, rock 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 blocking 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, and is the large problem being badly in need of solving.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of oil and gas pipes leather cup screw gasket set, and it can solve micro-leakage phenomenon of screw hole and bolt bearing, improves the sealing effect of pipeline.
In order to solve the problem, the utility model by the following technical solutions: a kind of oil and gas pipes leather cup screw gasket set, comprises plugging leather cup, block head; Wherein the sealing surface of plugging leather cup is provided with screw, at the upper end face part of screw mouth, is provided with protruding O RunddichtringO; Block head comprises front pressuring plate, rear fender, bolt, nut, and plugging leather cup is fixed between front pressuring plate and rear fender by nut by bolt.
Implement the technical solution of the utility model, there is following beneficial effect: oil and gas pipes leather cup screw gasket set described in the utility model, solve plugging leather cup and enter the problem that bolt position oil gas string leaks after pipeline, improve the sealing effect of pipeline, and adopt this device to largely overcome the not tight shortcoming of shutoff, increase work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, mode of execution of the present utility model is described further:
Fig. 1 is the structural representation of block head.
Fig. 2 is the structural representation of plugging leather cup.
1-front pressuring plate; 2-plugging leather cup; 3-rear fender; 4-bolt; 5-nut; 6-screw; 7-O RunddichtringO.
Embodiment
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 gasket set, comprises plugging leather cup 2, block head; Wherein the sealing surface of plugging leather cup 2 is provided with screw 6, at the position, exterior edge face of screw 6, is provided with protruding O RunddichtringO 7; Block head comprises front pressuring plate 1, rear fender 3, bolt 4, nut 5, and plugging leather cup 2 is fixed between front pressuring plate 1 and rear fender 3 by nut 5 by bolt 4.
When existing plugging leather cup 2 is sent into pipe-line by block head, leather cup is after being subject to the high pressure of oil gas, and protruding O RunddichtringO 7 can be compacted, thus realizes the effect of screw 6 sealing.
The above; be only the utility model preferably embodiment; 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.
