"Since the invention of Zhao technicians, the gate to take out the device, take out the gate has not been difficult, it is really effective and safe and labor-saving, an annual effect of more than 35,000 yuan. On October 11, Xiao Xingwen, an employee who is replacing the gate at No. 37 metering station in Jianghe Oil Production Management Area, Henan Oilfield Branch, said.

The equipment was invented by Zhao Yunchun, the chief technician of the district head.

At present, the sluice gates used in oil field technological process are corroded by fluid medium for a long time, and the internal corrosion is serious. There is a situation that the matching between the gate plate and the screw is not close. In the actual operation of the staff, the gate plate often falls off. In this case, the gate valve body is usually disassembled and the pry bar is used to remove the valve body. The square pried out the gate. Because the gate is slightly larger than the gate through the body diameter, connecting with the lead screw as a whole, prying the gate with pry bars is difficult and time-consuming, and there is often the imagination of pry bars slipping and bruising fingers. If the break off part is special, there will be pry bars can not pry out the gate, the entire valve will be scrapped, resulting in annual cost expenditure of more than 50,000 yuan.

In view of the above production difficulties, the production area quickly forms a technical research team. The main body of the device is a pair of supporting rods with two sections welded separately with "U" clips connected by a designed sliding sleeve in the vertical direction of both ends of a transverse main supporting rod. The lifting part is that the screw passes through the main support rod. The lower end of the screw is designed with different sizes of fishing claws according to different types of gate plate. The nut and the main support rod are connected with rolling bearings. Three rotating handles are welded above the screw. When removing the gate, just remove the gate cover, support the "U" type card of the auxiliary support rod of the device on the outside side of the valve, grab the falling gate plate by lifting part, rotate the handle on the other side, and remove the gate easily. It takes 5 minutes.

Through field test, the effect is remarkable, and has been popularized in the whole plant.

Through verification, the device can be operated by a single person, and the time is reduced from 40 minutes to 5 minutes. It can reduce the potential safety hazard to zero, and no longer fear that the gate can not be taken out and scrapped. It also improves the productivity of oil wells, and is loved by the first-line workers in the oilfield.
