Hanging ball valve pneumatic butterfly valve is used for hoisting equipment to install valves. Hanging ball valve pneumatic butterfly valve assembly components are composed of pneumatic butterfly valve steel frame and ball valve. The following section will introduce the design principle of the pneumatic butterfly valve for the bottom hanging ball valve.
1. The principle for determining the stiffness of pneumatic butterfly valve: the vibration of the engine has six degrees of freedom, including front and rear, left and right, up and down, yaw, pitch and roll (displacement along the X, Y, Z direction and rotation around the three axes). The elastic support layout should consider six degrees of freedom. When the elastic support (vibration pad) is arranged, the direction of the interference force should be mainly considered, The center of gravity of the equipment and the geometric dimensions of the elastic support arrangement. When the disturbing force passes through the center of gravity of the equipment and the direction is vertical, as long as the elastic support (damping pad) is arranged symmetrically according to the center of gravity, the stress on the elastic support arrangement is equal. When the frequency of interference force is greater than the natural frequency of the vibration isolation system composed of equipment and elastic support arrangement, the environment around the equipment will obtain good vibration isolation effect. When the mass distribution of the supported object is uneven, and the elastic support layout cannot be symmetrically distributed according to the center of gravity, the same type of damping pad with different stiffness can be used, so that the damping pad near the center of gravity has greater stiffness, and the damping pad far from the center of gravity has smaller stiffness, so that the resultant force generated by each damping pad is consistent with the center of gravity of the supported object.
2. The stability of the engine and transmission assembly damping pad is also an important factor in selecting the damping pad design scheme. The basis for ensuring system stability is that the minimum natural frequency of the system vibration mode is less than a certain frequency value.
3. In order to ensure that the damping pad has sufficient static bearing capacity to meet the requirements of the power transmission system of the loader for its service life, the rated static bearing capacity of the damping pad must be guaranteed while selecting the appropriate stiffness of the damping pad.
As the name implies, the pneumatic butterfly valve of the suspended ball valve is to install valves for the lifting equipment. The combined components of the pneumatic butterfly valve of the suspended ball valve are composed of the steel frame of the pneumatic butterfly valve and the ball valve. The shockproof principle of the pneumatic butterfly valve of the suspended ball valve absorbs the flexibility of the ball valve with different deflection values, and it is improved according to the rating of the required deflection value, The flexibility and expansion of the ball valve can achieve good rebound and elongation effects when the equipment is operating. At the same time, it has a good shock absorption effect on the lifting equipment, stabilizing and reinforcing the balance of the lifting equipment, and has a very strong protective effect.
The suspended ball valve damper (shock absorber) is used in the vibration reduction of small equipment such as fan coil units. During the installation project of central air conditioning, the vibration reduction installation of fan coil units can improve the operating condition of fan coil units, extend their service life, and reduce the noise and vibration pollution to the surrounding environment.
XHS hanging ball valve pneumatic butterfly valve: XHS hanging ball valve vibration damper (shock absorber) is used in the vibration reduction of small equipment such as fan coil units. During the installation of central air conditioning, the vibration reduction installation of fan coil units can improve the operating condition of the fan coil, extend its service life, and reduce the noise and vibration pollution to the surrounding environment. According to the actual installation requirements of fan coil units, our company has designed and produced HS type fan coil unit special shock absorber. This product has large damping, low natural vibration frequency, convenient installation and low cost, and is especially suitable for installation in places with high requirements for human settlements.
Applicable equipment: ceiling air conditioner, axial flow fan, fresh air fan, pipeline, etc.
