Technical Field
The utility model belongs to the technical field of the bleed valve for the oil exploration drilling equipment, concretely relates to bleed valve for oil exploration drilling equipment.
Background
In the petroleum exploration drilling process, effectively treating and discharging gas accompanied with petroleum production is an important link for ensuring the safe and efficient drilling operation. With the continuous development of petroleum exploration technology, the performance requirements on drilling equipment are also increasing.
In conventional oil exploration drilling equipment, there are often a number of problems with the purge valve used. First, it is poor in sealing performance. The sealing member is easily worn due to long-term use and frequent opening and closing operations, thereby causing gas leakage. This not only affects the normal operation of the drilling equipment, but may also cause safety hazards, such as fires, explosions, etc.
Second, the control of the gas discharge is not accurate enough. In the gas discharge process, the speed of the gas discharge is unstable due to the lack of effective diversion and flow rate control, and large noise is easily generated. The noise pollution can cause serious noise pollution to the working environment of the operation site, the physical and psychological health of workers is affected, and the error of judging the running state of equipment by the operators can be caused by noise interference.
Therefore, we propose a bleed valve for petroleum exploration drilling equipment, which not only can reduce noise, but also can make the sealing component have high tightness after being worn, and increase the service life of the sealing component.
