As a kind of component used to realize the on-off and flow control of pipeline system, soft-seal butterfly valve has been widely used in many fields such as petroleum, chemical, metallurgy and hydropower. The disc of the soft sealing butterfly valve is mounted in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully open.
Six categories of soft sealing butterfly valves:
1. Classification according to sealing surface material 1) Soft sealing butterfly valve: The sealing pair is made of non-metallic soft material to non-metallic soft material.
2) The sealing pair consists of a metal hard material to a non-metallic soft material: a metal hard seal butterfly valve. The sealing pair is composed of a metal hard material and a metal hard material.
2, according to the structural form classification 1) central sealing butterfly valve 2) single eccentric sealing coal valve 3) double eccentric sealing butterfly valve 4) three eccentric sealing è·º valve 3, according to the sealing form classification 1) forced sealing butterfly valve: elastic sealing butterfly valve. The sealing specific pressure is generated by the valve plate pressing the valve seat when the valve is closed, the valve seat or the valve plate is elasticized 2) the torque sealing butterfly valve is applied. The seal specific pressure is generated by the torque applied to the valve shaft. 3) The pressurized sealing butterfly valve. The seal specific pressure is generated by the valve seat or the spring seal element on the valve plate to produce 4) automatic sealing butterfly valve. The seal specific pressure is automatically generated by the medium pressure.
4. Classification according to working pressure 1) Vacuum butterfly valve. A butterfly valve with a working pressure lower than that of the standard atmosphere.
2) Low pressure butterfly valve. Nominal pressure PN "1.6MPA butterfly valve.
3) Medium pressure butterfly valve. The nominal pressure PN is a butterfly valve of 2.5--6.4 MPA.
4) High pressure disc valve. The nominal pressure PN is a butterfly valve of 10.0--80.0 MPA.
5) Ultra high pressure butterfly valve. Nominal pressure PN" 100MPA butterfly valve.
5, according to the connection method 1) wafer type butterfly valve 2) flange butterfly valve 3) ear type butterfly valve 4) welded butterfly valve 5, according to working temperature classification 1) high temperature butterfly valve. T" 450 °C butterfly valve 2) medium temperature disc valve. 120 ° C "T "450 ° C butterfly valve 3" normal temperature butterfly valve. -40 ° C "T "120 ° C butterfly valve 4) low temperature butterfly valve. -100 ° C "T "-40 ° C butterfly valve 5" ultra-low temperature butterfly valve. T "-100 ° C butterfly valve

Peeled Garlic is made of Fresh Garlic,there are two kinds fresh garlic, one is Normal White Garlic, another is Pure White Garlic. The fresh Garlic is peeled by the peeling machine or by hand.The Fresh Garlics Which are prepared for peeling are picked out carefully from various garlics. After peeling, we put them into plastic bags or bottles, then the plastic bags or bottles are putting into the cartons.
