Where is there a high-quality suspended ball valve damper?
Shanghai Dongfeng Shock Absorber Equipment Co., Ltd., located in Baoshan Industrial Park, is a modern professional vibration and noise reduction enterprise integrating design, development, manufacturing, sales, installation and maintenance. The suspended ball valve damper is one of the professional recommended products.
The shockproof principle of pneumatic ball valve for hoisting ball valve absorbs the flexibility of ball valve with different deflection values, and improves it according to the rating of the required deflection value index. The flexibility flexibility of ball valve can achieve good rebound and elongation effects when the equipment is operating, and has a good shock proof effect on the hoisting equipment to stabilize and strengthen the balance of the hoisting equipment, The protective effect is very strong.
As the name suggests, the pneumatic ball valve of hanging ball valve is to install valves for lifting equipment,
Characteristics of pneumatic ball valve for suspended ball valve:
It can effectively isolate low-frequency noise caused by vibration.
Anti slip design of ball valve, more safe and reliable. The bottom 30 degrees can be angled to avoid the vibration transmission caused by the lower pull rod contacting the vibration isolator shell, which also brings convenience to the construction.
The ball valve is designed with low natural frequency value, with high vibration reduction efficiency.
C. is adopted for mining bottom and top R.
Shock proof, can effectively avoid vibration transmission. The suspended outer frame is made of multi-layer antirust baking paint, which has been tested by salt spray test and has a long service life.
Hanging ball valve pneumatic ball valve assembly is composed of pneumatic ball valve steel frame and ball valve.
Suspended pneumatic ball valve -- one of the most commonly used pneumatic ball valves for industrial shock absorber equipment
Hanger shock absorber (hanging ball valve shock absorber) is mainly made of metal ball valve, combined with certain damping materials, and has the functions of low frequency, large damping, wide application range, and obvious vibration isolation and noise reduction effect. The hanger damper is a vibration isolation and noise reduction element combined with a steel ball valve and a series connection, which is suitable for vibration reduction of various pipes and fan coil units, fresh air units, variable air volume air conditioning boxes, axial flow fans, etc. The hanger shock absorber is easy to install, and the lateral damping block is used to increase the vertical damping coefficient, improve the longitudinal and transverse rigidity, and ensure the normal and safe operation of the equipment.
Shanghai Dongfeng Shock Absorber Factory is mainly engaged in the development and production of suspended ball valve shock absorbers (pneumatic ball valves), pipeline shock absorbers (pneumatic ball valves) and new damping shock absorbers. It is a professional manufacturer of pneumatic ball valves in China. Its products are widely used in various pipelines and equipment in industries such as steel, power generation, petrochemical, cement steel and urban heating, It has been applied to key projects in 31 provinces, cities and autonomous regions across the country. Its performance has spread all over the country and is trusted by users
