Pneumatic pipe type needle valve is usually do flow adjusting function is given priority to, the pneumatic ball valve is as quick to cut off the pneumatic pipe lines. As small valves, pneumatic tube road between them has a completely different characteristic and using effect. Pneumatic pipe and in the light of the needle valve by valve type, on the basis of the disc changes, at the end of the disc into needle shape, the disc sealing in the valve stem. When the hand wheel rotation valve disc up and down, when clockwise, the valve closed, traffic also will gradually become smaller, until all closed flow to seal. And pneumatic pipeline ball valve is cut off, when there is a case of an emergency need to quickly cut off the gas source, using the pneumatic pipeline ball valve. Pneumatic pipeline ball valve disc used to switch a sphere, the valve stem connection between the spheres, when the valve stem with the handle, turning the ball over the valve stem rotate 90 degrees to play the role of and hydraulic fitting supplier off. 90 degrees clockwise as closed, counterclockwise to open. So on the choice, if it is to do flow control type choice of the needle valve, faster on fast off flow requirements under the condition of big ball valves.
Periodically check the oil level is medium oil height, as appropriate to the oil mist detector, on a regular basis to remove water blocking device bottom dust accumulation of condensed water and impurities. Check the air pressure and adjust the flow of one-way throttle valve has enough opening and closing force, flexible motion. Check whether testing hole leakage or leakage, leaking air leakage need to replace the seal in time. Conclusion high pressure water descaling injection valve not only stable and controllable operation, also need to pay attention to safe operation.
Instrument type needle valve product features and maintenance work meter type needle valve there are generally two kinds of features, using features and structural characteristics. It determines the main use of performance hydraulic fitting manufacturer and use scope of the valve, belongs to the valve using features are: valve main categories, product type, valve parts, valve driving mode, etc. It determines the pneumatic ball valve valve installation, maintenance, maintenance methods of some structural characteristics. Belongs to the structural characteristics are: the valve and overall height, length and the structure of pipe connection form, the form of the sealing surface, stem structure, etc.
