Embodiment approach

[0008] It can be seen from the figure that the unidirectional flow control part is installed with a check valve seat 2 at the inner wall housing 1 in the direction of the inlet of the device. The diversion hole of the valve, the upper sealing surface 8 of the control valve 4 is also made into an inclined surface, which matches the sealing surface 3 of the valve seat 2, and a groove 9 is formed in the middle of the sealing surface 8 of the control valve 4, which can be built-in Sealing rubber ring. The valve body 4 of the control valve is a cylindrical structure, and more than two transparent body grooves 7 are evenly distributed in the horizontal direction as the liquid channel when the valve body is opened. A spring 5 is housed in the control valve valve body 4, one end of the spring 5 is fixed on one end of the valve seat 2, and the other end is fixed on the tail end 10 of the control valve penetrating body groove. When the production fluid of the oil well exceeds the set p...

Abstract

The anti-theft monoway valve is one kind of mechanical product for controlling the flow mode of raw oil and other liquid in petroleum industry so as to prevent theft. It consists of unidirectional flow control part, flow rate control part and anti-theft part mainly. The unidirectional flow control part consists of valve seat, control valve and spring; the flow rate control part consists of lead screw, lead screw seat, lead screw sleeve and lead screw sleeve sealing seat; and anti-theft part is installed in the end of the lead screw of the flow rate control part and has sealing barrel around the lead screw axis with anti-theft cipher lock.

Description

1. Technical field: [0001] The invention belongs to a mechanical product and relates to an anti-theft control device for the flow mode of crude oil or other liquids in the oil industry. 2. Background technology: [0002] At present, there are various check valves, valves and anti-theft valves on the market, but all of them have a single function. And the market is badly in need of a device that can combine check valves, general valves, and anti-theft functions. This product is currently lacking. In the process of crude oil production in oil fields, due to the poor social security situation in many places, criminals often cut off static oil pipelines to steal oil cases. After the wellhead pipeline is cut, not only the oil from the oil well will leak out, but also a large amount of crude oil from other oil wells in the oil gathering station will flow back. In order to reduce such losses, an anti-theft single-flow valve with simple structure and easy installation is urgently...
