High Pressure Ball Valve / High Temperature Ball Valve / Product

Product name: Q21N natural gas high pressure forged steel ball valve

Model: Q21N

Caliber: DN6-DN50mm

Pressure: 1.6-42.0MPa

Material: stainless steel, forged steel

Product introduction

Q21N natural gas high pressure forged steel ball valve is mainly applicable to the pipelines of various systems in thermal power stations, to cut or connect the pipeline medium. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, forged steel valves are characterized by high temperature and pressure, and a unique self-sealing design. The higher the pressure, the more reliable the seal. Due to the performance and technical characteristics and the special working conditions, the product has formed characteristics that other products cannot replace.

Second, Q21N natural gas high-pressure forged steel ball valve overview products:

Q21N natural gas high pressure forged steel ball valve is mainly applicable to the pipelines of various systems in thermal power stations, to cut or connect the pipeline medium. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, forged steel valves are characterized by high temperature and pressure, and a unique self-sealing design. The higher the pressure, the more reliable the seal. Due to the performance and technical characteristics and the special working conditions, the product has formed characteristics that other products cannot replace.

Q21N 天燃气高压锻钢球阀性能特点: Performance characteristics of Q21N natural gas high pressure forged steel ball valve:

1. Reliable sealing performance: The seal is embedded in the stainless steel valve seat, and the spring end of the metal valve seat is provided with a spring. When the sealing surface is worn, the valve continues to maintain a good seal under the action of the spring;

Fire protection structure: When the sealing surface is burned out, the valve seat and the ball are pushed to form a metal seal under the action of the spring force;

2. Automatic pressure relief function: When the medium in the valve is over the preload force of the spring, the valve seat at the outlet end backs out of the sphere to achieve the automatic pressure relief effect, and the valve seat automatically resets after pressure relief;

( 可选 ) :密封面受损后,通过辅助密封系统像密封面注相应的密封剂即可修复密封面; 3. Auxiliary seal setting system ( optional ) : After the sealing surface is damaged, the sealing surface can be repaired by injecting the corresponding sealant through the auxiliary sealing system like the sealing surface;

4 , labor-saving operation: the ball is supported by the upper and lower sleeves to reduce friction.

Q21N 天燃气高压锻钢球阀产品用途: Fourth, Q21N natural gas high pressure forged steel ball valve product use:

City gas: gas output pipelines, trunk lines and branch line supply pipelines;

Central heating: large-scale heating equipment output pipelines, trunk lines, branch lines;

Heat exchanger: opening and closing of pipes and circuits;

Iron and steel plants: various fluid pipelines, exhaust gas pipelines, gas and heat supply pipelines, fuel supply pipelines;

Various industrial equipment: various heat treatment pipelines, various industrial gas and heat pipelines.

Q21N 天燃气高压锻钢球阀安装注意 : Installation of Q21N natural gas high pressure forged steel ball valve

The end welding of all-welded steel ball valves is by electric or manual welding. Avoid overheating the valve compartment. The distance between the welding ends must not be too short to ensure that the heat generated during the welding process will not damage the sealing material. All valves should be opened during installation.
