Water type bottom valve

1、 Overview Each water pump needs to be equipped with a bottom valve, which is usually installed below the water surface, while the above water bottom valve is installed above the water surface. It is a replacement product of the old bottom valve and is an ideal water diversion equipment and can also replace vacuum pumps and vacuum pumping devices. SSDF-l underwater bottom valve is composed of parts such as valve body, disc, piston rod, valve cover, positioning column, etc. Before starting the water pump, fill the suction pipe with liquid to make the pump have sufficient suction force. Suck the liquid into the valve, open the piston valve disc, and carry out the water supply operation. When the pump is stopped, the valve disc closes under the action of liquid pressure and its own gravity, thereby preventing the liquid from returning to the front of the pump. The design of the underwater bottom valve is reasonable, the manufacturing process is advanced, and the installation, use, and maintenance are convenient. And it has the advantages of low friction resistance, long service life, energy conservation, etc. It is widely used as a water pump supporting facility in industries such as petrochemical, chemical, textile, printing and dyeing, metallurgy, mining, drainage and irrigation, etc.

J41H forged steel flange globe valve refers to a valve where the closing part (disc) moves along the centerline of the valve seat. According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the valve disc stroke. Due to the relatively short opening or closing stroke of the valve stem and the highly reliable cut-off function, as well as the proportional relationship between the change of the valve seat opening and the stroke of the valve disc, this type of valve is very suitable for regulating flow. Therefore, this type of valve is very suitable for use as a cut-off or regulating and throttling device.

All welded ball valves are widely used in city gas, city heating, petrochemical, shipbuilding, steel, pressure regulating station, power plant and other pipeline equipment.

Product features and usage: HTGLF47HR-10.16.25 series pipeline self operated control valve, also known as pipe operated valve. It is developed on the basis of absorbing micro resistance slow closing check valves, hydraulic control check butterfly valves, and multifunctional hydraulic control valves, and is a new generation product of water pump control valves. It combines the functions of an electric gate, an electric butterfly valve, and a check valve, and eliminates water hammer hazards through quick and slow closing actions, protecting the safety of the water pump and pipeline network. This valve is a new type of control equipment for pumping stations with novel structures, advanced performance, and reliable operation both domestically and internationally. It is mainly used in industries such as centrifugal pumps, metallurgy, petrochemicals, water companies, municipal engineering, and environmental protection for automated water supply and drainage pumping stations.

Plug valves are shutoff or plunger shaped rotary valves that open or close a valve by rotating 90 degrees so that the port on the plug is identical to or separate from the port on the body.

ZJHPF pneumatic film lined with fluorine single seat regulating valve, and fluid contact valve body wall and valve components are high pressure injection molding process, lined with corrosion resistance, aging resistance of polyperfluorinated ethylene propylene (F46), and the use of PTFE bellows seal.Widely applicable to acid, alkali and other strong corrosive media and toxic, volatile gas, liquid control.

Brief introduction of D943H electric telescopic butterfly valve: The electric telescopic butterfly valve is suitable for water supply and drainage, gas pipelines such as food, medicine, chemical industry, petroleum, electric power, textile, papermaking, etc. whose temperature is ≤80℃ and nominal pressure is ≤1.6MPa. The function of expansion and contraction.

The MDZ series magnetic driven high and low temperature centrifugal pump has flow components made of stainless steel or special steel. The product adopts a good hydraulic and efficient magnetic transmission structure, and a novel appearance design, achieving the advantages of stable performance and saving installation space of the magnetic pump. It has been widely used in mid to high end application fields.

Low temperature valves refer to valves that can be used under low temperature conditions. Valves with operating temperatures below -40 ℃ are usually referred to as low-temperature valves. Low temperature valves include low-temperature ball valves, low-temperature gate valves, low-temperature globe valves, low-temperature butterfly valves, low-temperature check valves, etc. They are mainly used in chemical plants such as 300000 tons of ethylene and liquefied natural gas. The output liquid low-temperature media, such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., are not only flammable and explosive, but also need to be gasified during heating. During gasification, the volume expands hundreds of times. Low temperature valves are one of the indispensable and important equipment in industries such as petrochemicals, air separation, and natural gas. The quality of these valves determines whether they can be produced safely, economically, and sustainably.
