SACP special check valve instruction manual I. Overview SAC dedicated check valve appearance, structural design is reasonable, the check valve flap open under the effect of fluid pressure, the medium by the import side. When the pressure on the inlet side is lower than the pressure on the outlet side, the valve flap is closed by the action of resetting the torsion spring, fluid pressure difference and gravity and other factors to prevent media backflow. Second, the use of soda ash dedicated check valve for nominal pressure PN1.0 ~ 4.0MPa, nominal diameter DN50 ~ 1200mm (NPS2 ~ 48), work 196 ~ 540 ℃ on the various pipelines to prevent media back. Through the selection of different valve materials, can be applied to carbon dioxide, MI, MIAII, half II, nitric acid, acetic acid, strong oxidizing media and urea and other specialty media. Note: When used in carbon dioxide medium, carbon dioxide temperature control can not be too high, because the dust in the carbon dioxide gas is easy to enter the gap, causing the valve flap stuck. According to the long-term use of soda ash industry experience, it is recommended carbon dioxide temperature control at 80 ~ 100 ℃ is appropriate, because the carbon control temperature is too high, can easily lead to screw compressor failure. Third, the structural characteristics 1. Structure length is short, the structure of the length of only traditional flange check valve 1/4 ~ 1/8; Small size, light weight, the weight of only traditional flange check valve 1/4 ~ 1/20; 3. Valve in the role of the reset torsion spring off more quickly, sensitive, water hammer pressure is small; 4. Horizontal pipe or vertical pipe can be used, easy to install; 5. Smooth flow path, fluid resistance is small; 6. Valve disc hole and the valve shaft in the design of a reasonable transitional rotation clearance, increasing the opening and closing of the valve when the valve sensitivity and sealing; Valve flap rotary stroke, closing the impact of small; 8. The overall structure is simple and compact, handsome in appearance; 9. With blow-blocking device, the valve cavity dust (crystallization, scarring, scaling) can be periodically purged with high-pressure steam; Long service life, high reliability. Four: common accidents and elimination methods: Leakage at the connection: the reason is not tight nut connection or uneven elastic gasket damage, remove the uniform tighten the bolts, remove dirt, replace the gasket. Seal leakage: the sealing surface dust, crystallization, scarring, fouling, eliminating the method of connecting the plugging device, the valve sealing surface can be regular high-pressure steam purge.
The Galvanzied Water tanks are used to provide storage of water for use in many applications, drinking water, irrigation agriculture, fire suppression , agricultural farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses.
The Panel size : 1000x1000mm, 500x500mm, 1000x500mm
Thickness :2mm, 3mm , 4mm, 5mm, 6mm
Use Q235A steel panel and press into 1220x1220mm, 1000x1000mm and 1000x500mm standard panel, make holes around Water Tank, through coated zinc surface treatment, and install on site. When installation, bolts and nuts collection and silicon sealing gaskets among panels.
The sectional panels shall be pressed to double flanges at the angles of 45 degree and 90 degree to the face of the plate on four sides.
All tanks are internally braced with angle stays to endure the rigidity of the tank when filled with the water .The top panel is supported by top panel support ,which shall be made of stainless steel grade 304 or 316 material according to requirement .
