Abstract: In the past, oil well valves in the oil fields were frequently subjected to arbitrary switch by the criminals, causing serious damage. The old valve operating areas were exposed. The valve's handwheel, copper bushing and screw were seriously damaged and the problem of theft was plagued with oil and gas. produce. Zhang Zhongqian, a member of the three-region oilfield operation and management unit in the No. 2 Production Plant of Zhongyuan Oilfield, has successfully developed the pumping well password lock-type valve anti-theft device. The device can achieve an annual profit of nearly RMB 1 million.

The code-locked valve anti-theft device is composed of six parts, which are anti-hammered, damaged jacket, password inner wheel, password outer wheel, pressure wheel, docking wheel, special tools and auxiliary parts. Each part can be arbitrarily disassembled and maintained, and the structure is simple. Small size, beautiful appearance, easy to operate.

The password-locked valve anti-theft device's valve switch is concealed in the jacket. When it is used, the special handle can be arbitrarily dismantled. Not only the cipher device can change the password, but also the code lock valve copper sleeve and the screw are equipped with a password jacket protection device. Avoid copper sleeves and screws flying out of accidents and improve their safety performance.

After the trial, the lock-type valve anti-theft device not only reduced the loss of oil and gas resources, but also avoided the cost of waste, while ensuring the personal safety of employees. According to a password-locked valve anti-theft device on a well, a 5,000-yuan calculation can be made. 200 wells can be dismantled and disassembled each year, and an annual profit of 1 million yuan can be achieved. Now, several million yuan has been created and considerable economic benefits have been achieved.
