Introduction and installation requirements of orifice plate

Introduction and installation requirements of throttle orifice plate. The standard orifice plate is a throttle device, which is a device installed on a pipeline filled with fluid. Throttle device is a branch of flow meter, which is divided into standard throttle device and non-standard throttle device. The standard orifice plate belongs to the standard throttling device.

What are the advantages of leak-proof gas drainers

The leak-proof gas drain is mainly composed of the drain body and the drain leak-proof device. The main functions of the leak-proof gas drain are: one is to use the height of the water seal to seal the gas and discharge the condensed water; the other is to reflect the height of the sealed water level in the drain; third, once the water seal in the drain is destroyed, The leak-proof device of the leak-proof gas drain seals the gas to prevent a large amount of gas leakage. By effectively curbing gas leakage, gas poisoning, fire and explosion can be prevented.

Performance of leak-proof gas drainers

Leak-proof gas drainers are mainly composed of gas leakage and leak-proof devices. Mainly used for overhead gas pipeline condensate discharge. When the effective water level of the drainer is abnormally lowered due to pressure fluctuation of the gas pipe network or other reasons, resulting in gas leakage, the leak-proof device can automatically close the end chamber drain outlet to prevent instantaneous overpressure breakdown. The floor drain anti-leakage device can effectively prevent gas leakage, thereby effectively preventing gas fires, explosions, poisoning and other malignant accidents.

Precautions for Installation and Maintenance of High Pressure Gate Valve

High-pressure gate valve, is the most widely used a valve, it is widely popular, is due to the opening and closing process between the tight cover friction is small, more durable, open height is not easy to manufacture, easy maintenance, not only suitable for low pressure, but also suitable for high pressure. Its closed principle is to rely on the valve bar pressure, so that the gate sealing surface and the valve seat sealing surface closely fit, to prevent the flow of media. High-pressure gate valve allows only one-way flow of medium, directional installation. Its structural length is greater than the gate valve, and the fluid resistance is large, and the sealing reliability is not strong during long-term operation.

Advantages and disadvantages of high pressure gate valve and classification

The type of high-pressure gate valve according to the position of the stem thread is divided into external thread type, internal thread type, flange, welding and so on. According to the flow direction of the medium, there are straight-through, DC and angular. High pressure gate valve is mainly divided into the following categories: JB/T2203-1999 "gate valve structure length" based on the general class.

Introduction to the working principle of high pressure gate valve

The opening and closing parts of the high-pressure gate valve are the gate plate. The movement direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The opening and closing parts of the high-pressure gate valve are the gate plate. The movement direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The movement of the stem, there are lifting rod type (stem lifting, hand wheel does not lift), there are lifting rotating rod type (hand wheel and stem rotating lift, nut is located on the valve body).
