Problems solved by technology

[0002] The gate valves used in choke manifolds for petroleum production are all straight-through parallel gate valves, wedge gate valves, and ball gate valves. When the shut-off gate valves are partially opened, the high-speed and high-pressure flowing medium impacts the gate valves. , causing severe vibration of the ram, which in turn causes damage to the sealing surface of the ram and the sealing seat, short service life and serious leakage
Although the spherical gate valve vibrates less than parallel gate valves and wedge gate valves during operation, the valve core and seat are all spherical, which is difficult to process, has low surface accuracy, poor mutual cooperation performance, and unsatisfactory sealing effect.

Embodiment Construction

[0012] like figure 1 As shown, the choke manifold inclined hole cylindrical valve seat can be adjusted. There are three rows of throttle holes on the circumference of the valve seat of the throttle valve. Adjust the throttle aperture of the throttle valve seat to achieve the purpose of throttling. The choke manifold oblique hole cylindrical valve seat adjustable throttle valve includes a valve body 1, a valve seat cover 2, a valve seat 3, a valve core cover 4, a valve core 5, an adjustable valve stem 6, a valve cover 7 and an anti-corrosion valve. Dust cover 8, valve seat cover 2 and valve seat 3 are installed in valve body 1, valve core cover 4, valve core 5 and adjustable valve stem 6 are installed in valve body 1.

[0013] In the adjustable choke valve of the present invention with a slanted hole cylindrical valve core valve seat of the choke manifold, three rows of choke holes are arranged on the circumference of the valve seat 3 .

Abstract

The invention discloses a choke manifold inclined hole cylinder valve core and valve seat adjustable throttle valve, which is characterized in that three rows of throttle holes are formed in the circumference of a valve seat of the choke manifold inclined hole cylinder valve core and valve seat adjustable throttle valve, the throttle holes formed in the upper part are larger, the throttle holes formed in the lower part are smaller, the throttle hole diameter of a throttle valve seat is regulated through regulating the vertical movement of a valve core of the throttle valve, and the throttling goal is achieved. The choke manifold inclined hole cylinder valve core and valve seat adjustable throttle valve comprises a valve body (1), a valve seat outer sleeve (2), a valve seat (3), a valve core outer sleeve (4), a valve core (5), an adjustable valve rod (6), a valve cover (7) and a dustproof cover (8), wherein the valve seat outer sleeve (2) and the valve seat (3) are arranged in the valve body (1), and the valve core outer sleeve (4), the valve core (5) and the adjustable valve rod (6) are arranged in the valve body (1).

Description

technical field [0001] The invention provides a throttling valve, in particular to an adjustable throttling valve with a cylindrical valve core and a valve seat with an oblique hole in a throttling manifold. Background technique [0002] The gate valves used in choke manifolds for petroleum production are all straight-through parallel gate valves, wedge gate valves, and ball gate valves. When the shut-off gate valves are partially opened, the high-speed and high-pressure flowing medium impacts the gate valves. , causing severe vibration of the ram, which in turn causes damage to the sealing surface of the ram and the sealing seat, resulting in short service life and serious leakage. Although the spherical gate valve vibrates less than parallel gate valves and wedge gate valves during operation, the valve core and seat are all spherical, which is difficult to process, has low surface accuracy, poor mutual cooperation performance, and unsatisfactory sealing effect.
