Brass internal threaded foot valve

The bottom valve,also known as the reverse stop valve, is a low-pressure plate valve, whose function is to ensure the single flow of liquid in the suction pipe, so that the pump works normally when the pump stops working for a short time, so that the liquid can not return to the water tank, and the suction pipe is filled with liquid to facilitate the start of the pump.

The valve is a kind of energy saving valve, generally installed in the bottom valve of the water pump suction pipe to limit the return of liquid water in the water pump pipe, mainly used in the pumping line.

The backflow preventer (online maintenance) is a device that our company has imported the American ANSI/AWWA C511-97 standard and strictly adheres to national standards (GB/T25178-2010) and industry standards Designed and manufactured by CJ/T 160-2012, it is a new type of hydraulic combination device widely used in tap water pipelines and various water systems to prevent pressure backflow pollution and siphon backflow pollution. It adopts a unique streamlined design, has the characteristics of short structure, small head loss, and flexible opening and closing of drainage valves, and all internal parts are made of stainless steel material. The company is the unit that formulates the national standard GB/T25178-2010 "Pressure Reducing Backflow Preventer".

High pressure butt welded ball valves have strong adaptability to pressure and temperature changes due to the valve seat being composed of carbon fiber reinforced Teflon sealing rings and disc springs, and will not produce any leakage within the marked pressure and temperature range. The machining process of the sphere is tracked and detected by advanced computer detectors, so the machining accuracy of the sphere is high. Due to the fact that the valve body material is the same as the pipeline material, there will be no uneven stress or deformation caused by vehicles passing through the ground, and the pipeline is resistant to aging. The sealing ring body is made of RPTFE material with a carbon content of 20%, ensuring complete leakage free (0%).

Hydraulic support pipes are made of high-quality carbon structural steel with appropriate addition of one or several alloy elements to improve the strength, toughness, and hardenability of the steel. After being made, this type of steel usually needs to undergo heat treatment such as quenching and tempering, chemical heat treatment, and surface quenching.

QJ41M high-temperature ball valve/QJ641M pneumatic high-temperature ball valve/QJ941M electric high-temperature ball valve is a ball valve that uses a new sealing material as the valve seat and is sealed with similar products such as polytetrafluoroethylene. Its service life has been increased by 3-5 times. High temperature ball valves have advantages such as stable performance, reliable sealing, low friction, lightweight opening and closing, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life. The structural length of high-temperature ball valves is consistent with that of globe valves, plunger valves, and drain valves, expanding the scope of ball valve use. They are widely used in industries such as petroleum, chemical, rubber, papermaking, and pharmaceuticals, and can replace globe valves, plunger valves, and fast drain valves. Applicable media: water, steam, heat transfer oil and other acids, operating temperature: ≤ 350 ℃. The ball and sealing ring in the high-temperature ball valve adopt special processing technology and the latest sealing materials, which make the surface roughness and roundness of the ball meet the standard requirements, thereby improving the sealing performance, service life, and high-temperature resistance. The timing plate moves the handle to drive the valve stem to rotate the ball, allowing the medium to pass smoothly.

Product Overview: One is a two-piece structure, with threaded connections in the middle and sealed with PTFE gaskets; Another type is a three piece structure, with bolts in the middle. Depending on the selected valve seat and gasket/packing material, it can adapt to different working temperatures and media. The product is mainly suitable for various high-pressure medium transportation pipelines in industries such as chemical, metallurgical, petroleum, and pharmaceutical industries, with a suitable temperature range of -196~450 ℃; Driving methods: manual, pneumatic, electric, hydraulic, turbo, etc; Nominal diameter: 1/2~12 "; Nominal pressure: 150LB~1500LB; Applicable media: water, gas, oil, natural gas, and acid-base corrosive media.

VSSJAFC type detachable double flange force transmission joint is composed of loose sleeve expansion joint, short pipe flange, force transmission screw and other components. It can transfer the pressure thrust of the connected parts (blind plate force) and compensate for pipeline error, and cannot absorb axial displacement.Important for pump, valve, pipeline and other accessories loose sleeve connection.

Elbow In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three kinds of 45° and 90°180° which are more commonly used. In addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°.
