Performance and use of the exhibition type discharge valve: easy to operate, open free, flexible and reliable movement; valve assembly and maintenance is simple, the sealing structure is reasonable, and the sealing ring replacement is convenient and practical. Structure: mainly by the valve body, valve, seal, valve stem, valve gland, bracket, handwheel, flanges, nuts, screws and other parts.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
On the exhibition type discharge valve, corrosion resistance: 1 using the media such as water, acetone, alcohol, ammonia, barium carbonate, benzene (WCB material temperature using -29 C -425 C). 2 the use of media such as particles, oil, paper pulp, carbon dioxide (stainless steel material can be used temperature -232 C -60 C). 3 prohibited the use of fluoride ionic liquids (such as HF) also cannot use alkali and phosphate (temperature less than 150 DEG C, the concentration of >30%). The general working temperature less than 4 stainless steel and 150 DEG C, the pressure range of 0.6-2.5MPA, more than the prescribed order to explain.
The difference between upspread and downspread:
1 folding opening and closing stroke
The opening and closing stroke is different, the installation size has the size of the upspread type and the downspread type feeding valve opening and closing stroke is small, the installation height is small. The mounting height of the rotating rod structure is small. During the opening and closing process, the plunger only rotates. It should judge the opening and closing and position of the valve according to the indicator of the opening and closing position.
Folding opening and closing moment
Upspread feeding valve for the disc upward movement valve open, open the valve to overcome the medium force, open than close torque.
Downspread, plunger feeding valve for the disc (plunger) downward movement of the valve open, open the direction of movement and the same force of the medium, so open the smaller than the closing torque.
