Pneumatic ball valves are widely used, but they are not suitable for all occasions. We need to select the appropriate pneumatic ball valves. So today we will talk about the scope of application of pneumatic ball valves.
When selecting pneumatic ball valve, we should first understand its characteristics, and then select it through the environment. The characteristics of pneumatic ball valve are that its shape can be designed as required, its stiffness can be adjusted, and it provides greater damping ratio, shear resistance, tensile resistance, compression resistance, and easier installation than the ball valve. Its disadvantages are high natural frequency, short service life, and limited service environment. Generally, the service environment temperature should be controlled between - 30-70 ℃. Some chemical corrosive environments should select the pneumatic ball valve with appropriate materials for use.
The common ones suitable for the production of pneumatic ball valves are: natural rubber, neoprene rubber, butadiene rubber; The market is full of pneumatic ball valves made of recycled rubber, which are hard to handle without ball valve performance, nonlinear load compression ratio, rough surface, poor damping effect and easy to age. Remember to choose carefully and avoid purchasing such pneumatic ball valves.
Application scope of pneumatic ball valve: First, the vibration source belongs to vibration isolation and noise control of high-frequency rotating mechanical equipment. For example, pneumatic ball valves shall be used when the rotation frequency of mechanical equipment such as fan, water pump, generator set and air conditioning host is more than 1000 revolutions; 2、 The impact frequency of stamping equipment should avoid the natural frequency of pneumatic ball valve. For example, punch, die-cutting machine, press, etc; 3、 Since pneumatic ball valves have the function of vibration reduction in all directions, they are widely used in automobiles, aerospace and navigation; 4、 Other mechanical equipment.
At the same time, due to the characteristics of the product itself, there are many occasions where the product industry is very inappropriate. First of all, it will become brittle at minus 30 degrees and lose its own elastic deformation. At this time, it will not have the effect of vibration reduction. Therefore, in a too cold environment, do not use class vibration reduction products to avoid the expected effect. It also cannot withstand high temperature. As long as it exceeds 75 degrees Celsius, its internal structure will change, and its elasticity will completely disappear. Of course, it will no longer have any damping function. If the temperature continues to rise, it may burn up. Therefore, if the shock absorber is used in a very high temperature environment, it should not be used, otherwise, it will not play the expected role in reducing vibration, and even may cause accidents.
According to the above explanation, we can conclude that we should use different products in different places, and different products will have different effects. However, no matter what products we use, we should fully understand the characteristics of the products in the early stage. Only when we choose the right products and use the right places, can the products really serve us.
