Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, specifically a novel intelligent electric control throttling valve with a balance hole. Background Technology

[0002] A plunger valve functions as a gate valve. Its structure mainly consists of a valve body, a valve core, a valve stem, and a handwheel. A sealing sleeve is installed in the inner cavity between the inlet and outlet of the valve body to dynamically seal with the outer cylindrical surface of the plunger. The end of the plunger is connected to one end of the valve stem. When the handwheel is rotated, the valve stem drives the plunger to move axially, thereby achieving opening and closing.

[0003] However, existing plunger valves have at least the following drawbacks: First, they achieve sealing by using a dynamic sealing fit between the outer surface of the plunger and the inner wall of the sealing sleeve. During opening and closing, there is a large frictional force between the plunger and the sealing sleeve, resulting in a large opening and closing torque. Second, when the valve is open, the medium directly impacts the inner wall of the sealing sleeve, causing significant scouring. Especially at the moment the plunger opens and closes, the high-speed fluid generates a large scouring force, which can easily damage the sealing sleeve and affect its sealing performance and service life. Third, the valve stem moves up and down together with the plunger during opening and closing, requiring a large installation space. Summary of the Invention

[0004] The purpose of this invention is to provide a novel intelligent electric control throttling valve with a balance hole to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model proposes a novel intelligent electric control throttling valve with a balance hole, comprising a valve body, which is a three-way valve. The lower part of the valve body has a bottom flange with a channel, which is fixed to the valve body by bolts and nuts. The side of the valve body has a side flange, which is fixed to the valve body by bolts and nuts. The valve body contains a valve seat and a valve core. The valve seat is located on one side of the bottom flange, and the valve core is located above the valve seat. The valve seat contains a bushing, which is fixed to the valve core by hexagonal bolts. The valve core is inserted from the top of the valve body and sealed by a valve cover and a locking nut. The valve core has a valve stem that passes through the valve cover and the locking nut and extends upward. An electric support is provided on the outside of the valve stem, which is fixed to the locking nut. An intelligent electric actuator for controlling the movement of the valve stem is provided on the electric support.

[0007] Preferably, an upper protective sleeve is provided inside the bottom flange, and a lower protective sleeve is provided above the upper protective sleeve. The lower protective sleeve extends into the valve body, and a sealing gasket ring is provided between the bottom flange and the valve body.

[0008] Preferably, the valve body is provided with a pressure relief valve, which is located on the other side of the side flange.

[0009] Preferably, the valve stem is inserted into the valve core via a guide key, and the valve stem is provided with a packing area between the valve cover and the electric support. The packing area consists of a packing gasket, an oil seal packing, and a packing gland from bottom to top.
