Pressure Gauge Needle Valve Beijing Pressure Gauge Needle Valve Pressure Gauge Needle Valve Manufacturer Pressure Gauge Needle Valve Price Pressure Gauge Needle Valve Content Introduction:
The pressure gauge needle valve produced by Beijing Pute Instrument Complete Factory is an important component of the instrument measurement piping system. Some of them mainly include stop valves and ball valves, which are used to open or cut off pipeline access.
The needle valve has the advantages of easy installation and disassembly, tight connection, good fire protection, explosion-proof and high pressure resistance, and good sealing performance. It is an advanced connection in power stations, oil refining, chemical equipment and instrument measurement pipelines. Type of valve
Performance of needle valve
American standard internal and external thread needle valve is an important part of the instrument measurement pipeline system, mainly including stop valve and ball valve, its function is to open or cut off the pipeline passage.
The ferrule angle needle valve has the advantages of easy installation and disassembly, tight connection, good fire protection, explosion-proof and high pressure resistance, and good sealing performance. It is the preferred choice in power stations, oil refining, chemical equipment and instrument measurement pipelines. A valve with an advanced connection method
Applicable principles for needle valve selection
For oil and natural gas transmission main lines, those that need to be cleaned and buried underground should use full-diameter, fully welded structures. If the needle valve is buried in the ground, choose a ball valve with full-bore welding connection or flange connection.
For product oil transportation pipelines and storage equipment, flange-connected needle valves are used.
Needle valves with flange connection and internal thread connection are selected for city gas and natural gas pipelines
Commonly used materials for needle valves
Needle valves usually consist of a valve body, a valve cover, and a valve disc. It is composed of (gate), valve seat, valve stem, heat plate, packing and driving device (hand wheel, gear box or pneumatic or electric device, etc.).
The material of the valve body and valve cover in the needle valve is the shell material (also called the main body material), the gate (valve disc), ball, valve seat, valve stem, and sealing seat are often called internal parts. There are fasteners, seals, etc.
Selection of needle valve materials
Generally speaking, needle valve materials should be selected according to this standard based on their parameters and material performance and should comply with the provisions of relevant product standards. Other materials with performance not less than that specified in this standard or as agreed upon in the contract between the supplier and purchaser may also be used.
