What is a globe valve?
Globe valve is a mechanism used to control or stop the flow of liquid or gas pipe. The glaod valve seat is in the middle and parallel to the pipe and the opening in the seat is closed with a disc or stopper. Globe valves can be structured to process the flow in both directions.
The global valve consists of a partition that divides the interior of the pipe, usually parallel to the length of the pipe. The partition contains an opening that is sealed with a disc or flat plug that is pushed down into the hole or seat, perpendicular to the pipe to stop the pipe flow. The structure called the bonnet off the pipeline holds the stem that is connected to the disk. The hand wheel at the top of the bonnet is used to manually screw the stem with the blade at the end until the disk is comforted against opening the seat. In large industrial applications, the GLOBUS valve can be sealed using an electric, pneumatic or hydraulic control instead of manual wheel.
These devices are sometimes referred to by JAKO throttle valves as they can reduce the pipe flow. If the sealing disk moves part of the road to open the seat, the space that the product can flow is limited and therefore the flow is limited. This type of valve offers good control to control the flow of liquid. Water pipes are often equipped with a ground valve, so the operator can control the water flow of pipes by opening the valve only partially or the whole path.
This valve can also be set to close with or against the flow of the product. If the product flows in the same direction that is closed, the flow helps to close the seals, but makes it difficult to open. Conversely, if the flow goes against the direction of the disk closure, it will be easier to open the valve and more difficult to close.
causes a partition inside the product valve valve to avert its direction to move over the counter. This angular movement means that the product cannot flow freely and causes a drop in the valve pressure. Globe valves are generally unsuitable for sludge or stronger substancesy that can be defended by a partition.
