Professional multifunctional pump control valve repair

Shanghai valve repair center is a professional valve repair, valve sales, valves do with the business, the company has a professional valve repair technical team, dedicated service and professional solutions to detect various types of valve sealing surface of the problem is the maintenance and manufacturing and integration business model. Our technical team has been serving in the country's various industrial and energy sectors water pipe network, community property, power, oil and gas, petrochemical, chemical, steel, pharmaceutical, boiler industries. Industry engineers and senior technicians, has a group of experienced, well-trained experts and field service valve repair personnel. Multifunctional pump control valve use, characteristics, maintenance precautions; use; multifunctional pump control valve JD745X type, with reference to imported products and domestic products of the same type of advanced design and manufacturing. The main purpose is to be installed on the pump outlet pipe high-rise building water supply systems and other water supply system to prevent the media back, to prevent water hammer and water hammer phenomenon, a valve both electric valve, check valve and water hammer eliminator three function, which can effectively improve the safety and reliability of water supply systems. Features; 1, eliminate water hammer effect. The slow opening, fast closing, slow closing to eliminate water hammer principle of integration of technology, to prevent water hammer pump and stop the pump to produce water hammer, 2, easy to operate. Just operating the pump motor hoist button, the valve that is in accordance with the rules pump automatically opened and closed. 3, energy-saving effect. Streamlined body with a full channel DC design, small pressure loss, flow, and the small size and light weight. Works; when the pump is turned on, the water pressure in the valve disc below, while water pressure through the inlet side of small ball and small filter also entered below the diaphragm, slowly open the valve and prevent pump water hammer. When the pump stops, the valve disc under the action of its own weight and the spring, the first rapid closure of 90% to prevent water back, stop the pump to prevent water hammer, the top end of the medium from the outlet into the membrane through the small ball and small filters the remaining 10% slows down the process of closing speed to produce a buffer to prevent pressure surge, to achieve quiet close. Maintenance and repair; multifunctional pump control valve is usually installed in the outlet of the pump, the pump is generally designed as a dual-use equipment or three with a preparation, it is recommended to use the exchange, so that the pumps and control valves to better rational use of time is not as usual use will lead to the valve stem and sealing sleeve stuck or corroded. If found early valve failure due to maintenance (such as using some years is recommended to replace all rubber seals).
