The product has wide load range, long working life, safe and reliable use. The WGD type upper and lower seats are equipped with anti-skid pads on the surface. For equipment with small disturbance and low emphasis, the WGD type electric butterfly valve can be directly placed under the equipment shock absorption pedestal without fixing: the WGD1 type upper seat is equipped with bolts to fix the equipment. WGD2 upper and lower seats are respectively provided with bolt and foundation bolt holes, which can be fixed down. Users can choose according to different needs and occasions.
The applicable working temperature of WGD series products is - 40 ℃ - 110 ℃, the natural frequency within the normal working load range is 2HZ-5HZ, and the damping ratio is 00.045-0.065. (After 150 fatigue tests, the damping butterfly valve is free of cracks and fractures, reaching or exceeding the relevant national standards).
According to whether the electric butterfly valve is rotating or not, the valve can be divided into fixed vibration damping and rotary vibration damping. Fixed vibration reduction refers to taking vibration reduction measures for fixed parts, such as electric butterfly valve of engine base; Rotating vibration reduction means that vibration reduction measures are taken for rotating bodies, such as rotor electric butterfly valve, bearing electric butterfly valve, etc.
Fixed vibration reduction mainly refers to base vibration reduction, which is widely used. Electric butterfly valve, butterfly valve electric butterfly valve, fluid electric butterfly valve, etc. can be used for base vibration reduction. Different electric butterfly valves are used according to different situations. Generally, electric butterfly valves are widely used.
It is an ideal damping material and has damping effect on vibration. It has great linear flexibility, can be almost stretched to fracture without losing its elasticity, and can withstand alternating stress without fatigue. Like water, it is almost incompressible, and only produces elastic deformation after compression, but its volume remains unchanged.
When the temperature is lower than - 30 ℃, the elasticity of the electric butterfly valve is significantly reduced, so the electric butterfly valve should not work in severe cold conditions; At the same time, it is not resistant to high temperature, and its working temperature should not exceed 75-80 degrees.
The compressive strength of is much greater than the tensile strength. The tensile length of is generally about 6 times larger than the compression distance. The natural vibration frequency is not the same under tension or compression.
