Tianjin Tanggu TWT Valve Co.,Ltd. products

CHDB weight type hydraulic accumulator hydraulic control /CHDC series hydraulic control butterfly valve of high degree of automation, local, remote and linkage control, using PLC intelligent control system, realize the text, touch screen and other user-friendly interface.

Guide ball valve to ensure that the stem will not be affected by high pressure fluid side thrust. The utility model relates to an adjustable packing seal type blowout proof bronze stem, which reduces the abrasion of the moving parts and prolongs the service life of the valve stem packing. Easy to repair, can be quickly repaired after the bonnet assembly is removed. Valve port and valve body are forged, PTFE PTFE seat, adjustable packing nut.

Can be equipped with a handle, worm gear, electric or pneumatic control device. Reduce the rotational torque, support the stem, and make it separate from the valve body effectively, reduce the wear of the valve stem. After polishing treatment, with the valve seat precision. To achieve zero leakage requirements of air tightness test. The opening and closing torque is small, prolong the service life of the valve seat.

Casting body, with sufficient strength to meet the requirements of the working environment, fluid flow will not be hindered. Elastic wedge, can automatically adapt to the pipe stress caused by the deformation of the valve body. The welded seat ring is sealed to prevent leakage. Stem: T - disc - stem connection to prevent stress applied to the side of the stem to ensure smooth operation. Packing: packing containing preservatives, avoid rust stem. Deep stuffing box ensures long service life of packing. Seat ring: the valve seat is sealed and welded, which can eliminate the leakage channel and prolong the service life.

Weld the seat ring and the seat ring is sealed and welded to help eliminate the leakage passage. The valve body is a casting, which can be subjected to greater stress at the critical point through the strengthening of the heavy steel. The disc stem ring connects the disc to the stem so that the disc can be rotated, and helps to ensure that the seat is tightly sealed and operated without fault. The stem has a long engagement with the yoke, which helps to align the seat seal accurately.

The exhaust process is smooth, can prevent the occurrence of pressure fluctuations or other destructive phenomena.

EV2000 series of regulating valve body by double sealing metal and elastic material, adopting axisymmetric shape design, so that the valve cavity flow area is always ring contraction, avoid throttling the exit to the axis, eliminating cavitation and vibration of pipelines and pipeline damage. Ideal for geometric design, the fluid is well guided within the streamline body. Even in the case of high pressure, the valve can effectively eliminate the differential pressure, the pressure reduced to low pressure, and will not produce vibration and cavitation phenomenon. From the entrance to the contraction section of the annular flow area of the continuous decline in the flow rate gradually increased, without cavitation, without cavitation damage energy conversion. Regardless of the position of the piston, the flow profile is annular, thus ensuring a perfect linear regulation characteristic.

With a cut-off valve, silent check valve, balance valve, anti freezing and anti vacuum qi stagnation, signal detection and other 5 kinds of functions. The end of the seat can be split, the bottom of the connection position makes the installation of the valve and pipeline docking easier. The built in bypass valve is convenient for the main channel drainage, which can effectively prevent the freezing damage and the vacuum negative pressure zone at the outlet of the pump. External thread connection for flow regulation.

Light weight, compact clamping structure. Resilient seat with excellent performance and air tight shutoff. Double spring evenly distributed load force, the reaction is more rapid. Valve lining: can provide several synthetic rubber materials to meet the needs of most corrosive applications. Flexibility of installation location. Reduce the pressure loss, improve the dynamic response characteristics, eliminate the valve vibration..

The EX700 series includes AY gland loose compensation joint, AF flange loose, BY gland loose joint compensation limit compensation joint, BF flange loose limit compensation connector, CF flange loose force compensation joint and D type large deflection loose tube compensation joint and other forms, meet the different working conditions. Reasonable product structure design, reliable sealing performance, easy installation and disassembly. The utility model has the advantages that the utility model can freely stretch in the allowable range, and can compensate the axial displacement, the deflection and the eccentricity in a certain range of the pipeline.
