What are the benefits of damping pneumatic butterfly valves?
Damping is one of the three basic elements for controlling oscillation. However, its performance parameters are difficult to test and its damping effect is difficult to predict. Therefore, in general, the first way to stop the vibration control is to add mass, change stiffness, add vibration isolators or dynamic vibration absorbers, while in some special places, the damping method is required. For example, some thin plate shock absorbers, which make people feel helpless, can obtain satisfactory results by using damping methods.
Damping damper has the following benefits: it can suppress the oscillation peak value at the resonance frequency; Reduce the transmission of oscillation along the structure; Reduce construction noise. It is worth pointing out that damping is the most useful for suppressing oscillations in the resonant region, but it is less effective in the non resonant region.
The damping tension spring vibration damping has two advantages: the low frequency of the tension spring vibration damper and the large damping of the rubber vibration damper. By separating the advantages of the two points, the phenomenon of amplitude surge when the tension spring vibration damper resonates is eliminated, and the problem of high natural frequency of the rubber vibration damper is solved. It is an active and passive vibration isolation aspiration commodity. The ZD damping tension spring shock absorber has a wide load range and strong compliance. It can simultaneously produce significant effects on active vibration isolation, passive vibration isolation and impact vibration isolation. It is a multi-functional universal vibration isolation commodity and is suitable for the operating environment at - 20 ° C-80 ° C. Its natural frequency within the normal operating load range is between 1.5Hz and 4.9Hz, and the damping ratio is 0.065. It is an air conditioner, constant temperature equipment, fan Cooling tower, refrigeration unit, compressor, water pump and other airborne equipment are aspiring vibration reduction products.
Damping vibration reduction is mainly completed by using the inherent characteristics of damping data and the reasonable design of damping structure. Damping data is a new type of special data developed in the past decade, which has gained increasing effect in many fields. It is a kind of polymer data, which has high damping characteristics when changing modes, that is, it can consume energy when deforming, and can stop the peak value of structural oscillation in a wide frequency range.
Damping data can be divided into two categories, one is damping plate similar to rubber plate, the other is damping coating similar to rubber material.

Today, let's talk about the member of pneumatic butterfly valve with anti vibration function - the screw type pneumatic butterfly valve produced by Shenyang Yuante Rubber&Plastic Co., Ltd. is composed of three parts, namely, bellows, mesh sleeve, joint/flange, and its main body is bellows. Bellows have good flexibility. Because the longitudinal stiffness and bending stiffness of bellows are small, the screw pneumatic butterfly valve can work smoothly within the rated bending radius. The screw pneumatic butterfly valve also has the characteristics of high pressure resistance, high temperature and low temperature, corrosion resistance, light weight, toughness, etc., so it has a wide range of applications, such as aerospace, petrochemical, mining electronics, machinery and shipbuilding Medical and health care, textile electronics, energy buildings and other fields, so it also has a certain function of shock resistance, which can absorb stress and compensate displacement Specification: DN8~DN400 Origin: Shenyang Pressure rating: 0.6Mpa-6.4Mpa Connector modes are complete Functions: absorb vibration, reduce vibration and noise, compensate the displacement of pipe joints, ambient pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa, 4.0Mpa pneumatic butterfly valve joint mode specification: ISO standard taper pipe thread, NPT, JIS standard taper pipe thread can choose external thread or internal thread connection mode Product material: corrugated pipe - 304, 316, 321 and other stainless steel mesh sleeve: 201, 204, 304, 321, 316 stainless steel joints - optional use of pneumatic butterfly valve
Pneumatic butterfly valve is commonly used in the tank farm to avoid the sinking of the tank farm's foundation, which may lead to the fracture of the pipeline connected to the tank farm's pipe orifice. If pneumatic butterfly valve is used, it can absorb the sinking amount. The flexibility of pneumatic butterfly valve is relatively large. Shenyang Yuante pneumatic butterfly valve is one of the member units of China Rubber Industry Association. It has many advanced technical equipment imported from abroad. The pneumatic butterfly valve consumed is used to escort flexible components of various media. Its characteristics are: corrosion resistance, high temperature resistance, low temperature resistance (- 196 ℃~+420 ℃), light weight, good flexibility, and universal user aviation, Aerospace, petroleum, chemical industry, metallurgy, electricity, paper making, avoidance, wood, construction, medicine, tobacco, food, transportation and other different categories all have special pneumatic butterfly valves. It is the first choice for Ping An to choose the guaranteed merchants. Shenyang Yuante Rubber&Plastic Co., Ltd. welcomes you to negotiate!
