[0002] Most of the gate valves currently used in China are wedge gate valves, parallel gate valves and ball gate valves. When the wedge gate valves and parallel gate valves are partially opened, the high-speed flowing medium impacts the gate, causing the gate to vibrate. , and the vibration causes damage to the sealing surface of the gate plate and the gate seat, and the service life is short; although the spherical gate valve has little vibration, it is better than the wedge gate valve and the parallel gate valve, but the valve core and the valve body are spherical, and the processing is very difficult. Poor sealing performance

The invention discloses a high-pressure metal sealing rotary column valve for oil extraction. The high-pressure metal sealing rotary column valve is characterized by comprising an O-shaped seal ring (1), a seal check ring (2), a high-pressure oil nozzle (3), a hand wheel (4), a valve cap (5), an O-shaped seal ring (6), a valve core (7), a valve seat (8), a square seal ring (9), a valve body (10), an O-shaped seal ring (11), a nut (12), a support ring (13) and a nut (14), wherein the valve seat (8), the valve core (7) and the valve cap (5) are arranged on the middle part of the valve body (10); and the hand wheel (4) and the high-pressure oil nozzle (3) are arranged on the upper part of the valve core (7). The high-pressure metal sealing rotary column valve replaces a wedge type gate valve, a parallel gate valve and a spherical gate valve, so that the oscillation phenomenon that a gate is impacted by media flowing at a high speed is eliminated, and the problems of difficulty in machining, high cost and low sealing quality of the spherical gate valve are solved; and the high-pressure metal sealing rotary column valve has a simple structure and long service life, and is easy to manufacture.
Description
technical field [0001] The invention relates to a sealing spool valve, in particular to a high-pressure metal sealing spool valve for oil production. Background technique [0002] Most of the gate valves currently used in China are wedge gate valves, parallel gate valves and ball gate valves. When the wedge gate valves and parallel gate valves are partially opened, the high-speed flowing medium impacts the gate, causing the gate to vibrate. , and the vibration causes damage to the sealing surface of the gate plate and the gate seat, and the service life is short; although the spherical gate valve has little vibration, it is better than the wedge gate valve and the parallel gate valve, but the valve core and the valve body are spherical, and the processing is very difficult. Poor sealing performance. Contents of the invention [0003] The purpose of the present invention is to provide a high-pressure metal-sealed rotary spool valve for oil production, on the basis of a bal...
