Angle globe valve

I. Overview of Angle Globe Valve

启闭件是塞形的阀瓣,密封面呈平面或锥面,阀瓣沿流体的中心线作直线运动。 The angle shut-off valve is a plug-shaped valve disc. The sealing surface is flat or conical. The valve disc moves linearly along the center line of the fluid. The movement of the valve stem can be lifted (the stem is raised and lowered, and the hand wheel is not raised and lowered), and there is also lifted and rotated (the hand wheel and the stem are raised and lowered together, and the nut is set on the valve body). The corrugated globe valve is only suitable for full open and full close, and it is not allowed to adjust and throttle.   只许介质单向流动,安装时有方向性。 The API shut-off valve only allows the medium to flow in one direction, and it is directional during installation. Its structure length is longer than the gate valve, and at the same time, the fluid resistance is large, and the sealing reliability is not strong during long-term operation.

Introduction to Angle Globe Valve

Angle shut-off valve is a compulsory sealed valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve 6 from below the valve disc, the resistance to be overcome by the operating force is the frictional force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve. The diameter of the stem should be large, otherwise the failure of the valve top bending will occur. After the self-sealing valve appeared, the medium flow direction of the shut-off valve changed from the upper part of the valve disc into the valve cavity. At this time, under the action of the medium pressure, the force to close the valve is small, and the force to open the valve is large, and the diameter of the valve stem can be correspondingly To reduce. At the same time, this type of valve is also tight under the action of the medium. China's valve "three chemical supply" has stipulated that the flow direction of the shut-off valve will be used from top to bottom.

Three, angle stop valve opens

When the angle cut-off valve is opened, the opening height of the valve disc is 25% to 30% of the nominal diameter, and the flow has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the shut-off valve should be determined by the stroke of the disc.
The type of liquefied gas stop valve is divided into external thread type and internal thread type according to the position of the stem thread. According to the flow direction of the medium, there are straight-through, direct-current and angular. The shut-off valve is divided into sealing forms, and it has a packing-sealed shut-off valve and a bellows-sealed shut-off valve.
Installation and maintenance of angle globe valve The handwheel and handle operated globe valve can be installed in any position of the pipeline.
Handwheels, handles, and moving mechanisms are not allowed for lifting.
The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body.
High-temperature and high-pressure shut-off valves, also known as cut-off valves, are the most widely used valves. They are popular because of the low friction between the sealing surfaces during the opening and closing process, which is relatively durable, the opening height is not large, and the manufacturing is easy. , Easy maintenance, not only for low and medium voltage, but also for high pressure. Its closing principle is to rely on the pressure of the valve rod to make the sealing surface of the valve disc and the sealing surface of the valve seat closely to prevent the flow of medium.
The insulation cut-off valve only allows the medium to flow in one direction, and it is directional during installation. Its structure length is longer than the gate valve, and at the same time, the fluid resistance is large, and the sealing reliability is not strong during long-term operation.
Angle globe valves are divided into three categories: straight-through, right-angle and DC-type oblique globe valves.

Installation and maintenance of angle globe valve

1. Stop valves operated by handwheels and handles can be installed at any position in the pipeline.
2. Handwheels, handles and moving mechanisms are not allowed for lifting.
3. The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body.
