Product name: Q61N three-block high pressure ball valve
Material: Stainless steel
Product introductionThe three-block high-pressure ball valve is made of a three-section valve body with a bolt in the middle. It has the action of rotating 90 degrees, the cock body is a sphere, and has a circular through hole or channel through its axis. It is mainly used to cut, distribute and change the flow direction of the medium in the pipeline. It only needs to be rotated by 90 degrees and can be closed tightly with a small torque. Suitable for use as on / off valve.

It has the action of rotating 90 degrees, the cock body is a sphere, and has a circular through hole or channel through its axis. It is mainly used to cut, distribute and change the flow direction of the medium in the pipeline. It only needs to be rotated by 90 degrees and can be closed tightly with a small torque. Suitable for use as on / off valve. The three-piece high-pressure ball valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom-loaded structure with an inverted seal. When the valve cavity is abnormally pressurized, the valve stem will not be punched out. Valve body casting adopts advanced technology introduced in Taiwan, with reasonable structure and beautiful appearance. Drive mode: manual, electric, pneumatic. A 90 ° switch positioning mechanism can be set and locked as required to prevent misoperation. The three-block high-pressure ball valve has a reliable seal, a simple structure, and the sealing surface and the spherical surface are often in a closed state. It is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane, and ethylene. It has been widely used in various industries. The valve body can be integral or combined.
The main parameters of one or three block high pressure ball valve:
1. Product brand: Jiangsu Zhongli
2. Product model: Q61N
3. Nominal caliber: DN6-DN50
4. Pressure: 16MPa-42MPa
5. Main material: stainless steel
6. Applicable medium: water, oil, gas, acid and natural gas, etc.
Product features of two or three block high pressure ball valves:
1. The single valve seat design eliminates the problem that the medium in the cavity of the valve affects safety due to abnormal pressure rise.
2. Low-torque design and special structure design of the valve stem can be easily opened and closed with a small handle.
3. There is no friction during opening and closing. This function solves the problem that the traditional valve affects the sealing due to the friction between the sealing surfaces.
4. The three-piece structure can directly check and repair the valve installed on the pipeline, which can effectively reduce the shutdown of the device and reduce the cost.
5. The wedge-shaped sealing structure makes the sealing of the valve not affected by the pressure difference of the pipeline, and the sealing performance is reliably guaranteed under various working conditions.
6. The self-cleaning structure of the sealing surface eliminates the local erosion of the valve seat by high-speed fluid, and also removes the accumulation on the sealing surface to achieve the purpose of self-cleaning.
Three, three-block high-pressure ball valve advantages:
1. Easy installation, can be installed in any position in the pipeline in any direction.
2. The sealing ring material has the properties of high temperature resistance, high pressure resistance and corrosion resistance.
3. The passage in the valve body is smooth and can transport viscous fluid, slurry and solid particles.
球体与阀杆铸为一体，防止由于压力变化引起阀杆冲出承压件内的可能性，根本保证使用中的安全性。 4. The three-piece high-pressure ball valve ball is integrally cast with the valve stem to prevent the possibility of the valve stem punching out of the pressure-bearing part due to pressure changes, and to ensure safety in use.
