if groove gate valve working condition in the center of the opening, the slippery course on both sides of the valve plate due to is to rely on strong point, when the full close together, and when the middle part, valve plate and the big slide rail gap caused by vibration. Thus, even in the low incidence of cavitation area, make the throttle Industrial Valves operation for a long time, the slide will produce deformity, wear or damage, and because of the high pressure gate valves are not all-around touch, the touch location surface working pressure is very high, usually caused by biting the corrosion or conglutination, therefore, is not suitable for to flow monitoring. Also want to pay attention to, gate in small open degree, total flow change is big, if emergency opening and closing, the valve would result in higher working pressure sharply or negative pressure, is very close the valve of water hammer.

groove gate Industrial Valves from fully open to the opening of the middle of the valve fluid density is small, close to full close, significantly enhance fluid density. The category of large fluid density change smaller, at close to full close, total flow change is very big, don't close to turn off the valve when the application, this time is difficult to carry out the adjustment of the traffic. If the valve opening is very small, the outlet flow quickly, can make the gate underside causes cavitation, and accompanied by a violent vibration and noise, the throttle valve to run for a long time, often make the plate and the valve inner metal materials in cavitation.

clear orderly groove gate valve sealing storage of components, for installation. The whole installation process provisions of the following:

1, installation workshop to ensure clean, or to build temporary clean areas, such as buy weaving cloth or plastic etc, to avoid the installation of the dust into the whole process.

2, assembly workers safety work with clean cotton clothing, pure cotton padded cap, wearing a hair can not exposed, wearing clean boots, wearing plastic gloves, skim.

3, installation, use special tools for degreasing cleaning before installation, ensure clean.

groove gate Industrial Valves parts before assembling process through the following address:

1, according to production and processing, part of components must solve, do fine polishing surface can not have burrs, etc in production and processing;

2, all parts for degreasing solution;

3, skim conducted after phosphating treatment, cleaner phosphorus content;

4, pickling passivation after purification with mineral water clean and tidy, can not have drug residue, carbon steel components to eliminate this process;

5, each parts with no cloth to wipe, can not cable hair remaining components such as surface, or use a pure N2 to carry out the drying;

6, with no proof cloth or pure alcohol with high precision filter analysis for each component for scrubbing, until there is no dirty color.
