What does the calibrated flow of stainless steel pneumatic insulation butterfly valve mean? Rubber pneumatic butterfly valve can be used in railway locomotives and railway sleeper pads?
Rubber pneumatic butterfly valves can be used in many fields, but they are not suitable for all places. So how should we choose suitable rubber pneumatic butterfly valves? I have sorted out the characteristics of rubber pneumatic butterfly valve and its advantages and disadvantages for you before. Do you remember? It doesn't matter if I don't remember. I will recall a little later, mainly to talk about the scope of application of rubber pneumatic butterfly valves.
When selecting pneumatic butterfly valve, we should first understand its characteristics, and then choose the environment. The characteristics of rubber pneumatic butterfly valve are that its shape can be designed as required, its stiffness can be adjusted, its damping ratio is greater than that of the spring, its shear resistance, tensile resistance, compression resistance, and its installation is simpler. Its defects are high natural frequency, short service life, and limited operating environment. The temperature of ordinary operating environment should be controlled between - 30-70 ℃, and some chemically corrosive environments should select rubber pneumatic butterfly valves suitable for materials.
The main rubber pneumatic butterfly valves suitable for consumption are: natural rubber, neoprene rubber, butadiene rubber; The market is full of pneumatic butterfly valves made of recycled rubber, which are hard to handle without springiness, non-linear load compression ratio, rough surface, poor damping effect and easy to age. Remember to choose carefully and avoid purchasing such pneumatic butterfly valves.
Main application scope of rubber pneumatic butterfly valve:
1. Rubber pneumatic butterfly valve for automobile
2. Rubber damping products for railway locomotives and railway sleeper pads
3. Rubber pneumatic butterfly valve for bridge
4. Rubber pneumatic butterfly valve for construction engineering
Because rubber shock absorber has the above characteristics, it is widely used on the bogie of the running part of the locomotive. The rubber pneumatic butterfly valves used on electric locomotives include central support rubber cones, axle box pull rod elastomers, side bearing rubber stacks, motor suspension rubber pads, elastic wheels, elastic gears, air springs, bow rubber blocks and ball hinges of transmission devices, coupler rubber buffers, etc.
The rubber pneumatic butterfly valve applied to locomotives is mainly used to withstand the contraction stress, shear stress and modification torque, as well as the combined action of two or more stresses at the same time. Various rubber pneumatic butterfly valves have certain special performance and play an important role in each other. The speed of the railway locomotive has improved from time to time, and the dynamic effect on the line has increased sharply, causing fierce wear of the line, tire and components of the running part of the locomotive. As a result, the application of rubber pneumatic butterfly valve is getting more and more advanced.
From the above, we can draw a conclusion that we should use different products when using different centers, and different products will produce different effects. However, no matter what products we use, we should fully understand the characteristics of the products in the early stage. Only by choosing the right products and using the right center, can the products really serve us. Our Songxia Xizhen Pneumatic Butterfly Valve Co., Ltd. has different shock absorption products. Welcome to choose!
Carefully check the hidden danger of the wharf pneumatic butterfly valve
From February 7 to 8, the "battle" of pipeline inspection of Jinling Petrochemical highlighted the special inspection of pneumatic butterfly valves. Technicians walked through the company's 12 wharves along the Yangtze River and thoroughly investigated all pneumatic butterfly valves loaded and unloaded. 13 pipeline hazards were handled in a timely manner.
These two days are just the rest days. Experts and technicians from the Safety and Environmental Protection Department, the Consumption Scheme Department, the Mobility Department, the Information and Measurement Center, the Oil Storage and Transportation Department and other departments of the company arrive at the Yangtze River early every morning. They "filter" from wharf to wharf. The oil delivery hoses erected on each trestle, the hoses used by each barge for loading and unloading, especially the joints at both ends of the hoses, are screened one by one. Each section of hose is only confirmed to be safe and reliable after being signed by the gatekeepers of five departments.
During the inspection, 13 hidden dangers of pneumatic butterfly valves were found. On the same day, the pneumatic butterfly valves at both ends of the 0 # diesel fuel metering meter at No. 10 Wharf were stopped changing. The other 12 problems were being rectified according to the rectification plan.
