1, the pump starts before the valve at static pressure off. After the pump is started, the water enters the lower chamber of the diaphragm chamber from the bypass pipe at the inlet of the valve and slowly lifts the diaphragm together with the valve stem and the small valve plate. At the same time, the large valve plate opens immediately under water pressure. 2, with the inlet flow and pressure increases, the diaphragm together with the valve stem and large and small valve plate to the rated height (intuitive signal rod). Today's Focus: • Analysis and Outlook of Domestic Mold Steel Market • Demand for Construction Steel in China Will Continue to Increase • Startup Requirements for Environmental Protection and Energy Conservation • "National Standard for Ceramic Tile" 3, When the pump is stopped, Pressure is reduced, the large valve plate under the weight and return pressure rapid decline, until the full contact with the valve seat. 4, as the backwater pressure increases, the water from the outlet side of the bypass pipe into the diaphragm chamber, pushing the diaphragm along with the valve stem and small valve and valve slowly down. At this moment, the water in the lower chamber of the diaphragm chamber flows back to the inlet end through the bypass pipe on the left side of the valve. When the small valve plate completely closes the annular discharge port between the large valve plate and the valve stem, the valve is fully restored to the static pressure closed state before the pump starts. Automatic water control valve failure causes and precautions First, the signal rod lift speed is not normal because: 1, by-pass valve or filter blockage; 2, pressure plate or rubber membrane rupture or too many debris in the mold room ; 3, small valve was artificially closed. Second, the troubleshooting measures are: 1, check the position of the handle of the bypass valve is correct; 2, clean the valve and the filter; 3, check the rubber diaphragm chamber, if the rubber diaphragm or pressure plate rupture must be replaced immediately. Third, the internal leakage is too large because: 1, large and small valve plate seal damage; 2, large and small valve plate debris block; 3, valve seat or valve stem debris. Four, trouble-shooting measures are: · China Building Materials Network - Building Materials A little pass ranked the top three, disdain for peer · Wind and rain together for five years · Excellent Building Materials Enterprise Webcast 1, check the large and small valve plate rubber seals, as already Damage immediately replaced; 2, stop the pump to remove large and small valve plate, valve seat and valve stem debris; 3, reassembly, the parts must be cleaned.
Automatic vacuum Foaming Machine, adopt batching technology, foaming in vacuum condition. It is
composed of storage tanks, batching, mixing, vacuum, mould, and computerized controlling systems. It can be realized
numerical control during the whole production. It is used for making all kinds of foam.
Advantage: *The volume of the foam size can be 30% increasing at the same foaming formula.
* Reduce the chemical consumption and production cost.
* Suction and filtrate the foaming air. Environmental Protection.
* Monitoring the whole process of foaming by CCTV .
* Base plate can be Lifting automatically: it makes the sponge with uniform density and flat top by using
this way.
* Easy cleaning function.
* It can be realized numerical control with accurate and convenient ration during the whole production. And
it becomes more easily and stable to operate the machine
. * Continuous foaming.
* Flat top pressing device.(Additional)
