YJ41H Antibiotic Stop Valve Product Introduction:

The opening and closing part (valve disc) is driven by the valve stem and moves in a straight line along the axis of the seat (sealing surface), so that the pipeline is connected or cut off. Compared with gate valve, the valve structure is simple, usually only one sealing surface on the valve body and valve disc, sealing area is small, saving valuable materials, low cost, so the manufacturing process is better and easy to maintain. Sealing surface wear and abrasion light, good sealing. When opening and closing, there is no relative slide between the disc and the sealing surface of the valve body, so the wear and abrasion are not serious, the sealing performance is good, and the service life is long. The opening height is small, generally only 1/4 of the diameter of the valve seat channel, compact structure, saving installation space. The valve has strong sterilization and detoxification function to prevent the product from being contaminated with bacteria.

Widely used in biological fermentation, medicine and beer fermentation, amino acid fermentation, biological pesticide fermentation, biological fertilizer fermentation, various antibiotic fermentation, biological, biochemical, chemical and pharmaceutical materials, water, steam, cold control and other fields, the bottom can be opened according to customer needs, high temperature resistance long service life, no dead Angle to reach zero leakage level.

YJ41H Antibiotic stop valve product working principle:

The hand wheel is fixed at the top of the valve stem for rotary lifting motion. When the hand wheel is rotated clockwise, the stem thread is rotated down, and the sealing surface of the valve disc and the sealing surface of the seat are tightly sealed to reach the closed state; When the hand wheel is rotated counterclockwise, the stem thread is rotated upward, and the sealing surface of the valve disc and the sealing surface of the seat are detached and opened.

In order to "low into high", the valve starts to close from the fully open position, and the resistance to be overcome is the thrust caused by the friction resistance of the valve stem and packing and the medium pressure on the flap section (axial). With the decline of the valve flap, the fluid forms a pressure difference before and after the valve flap, preventing the valve flap from falling, and this resistance will increase rapidly with the decline of the differential valve flap. With the valve completely closed, the valve stem rotation strengthens the sealing force, the pressure difference between the front and back of the valve disc reaches the maximum working pressure of the medium, and the valve stem bears the maximum closing torque. During the valve opening process, the thrust formed by the medium pressure or the pressure difference between the front and back of the valve disc is the same as that of the valve opening, but it should be pointed out that at the opening moment, because of the large static friction moment between the sealing surface to overcome, the opening operating moment may also exceed the closing moment.

When the operation is completed, it is also bactericidal and detoxifying to prevent the product from being contaminated with bacteria. The YPT exhaust valve is used to discharge clean dirt. Keep this valve antibacterial.

Design features:

① It has strong sterilization and detoxification function to prevent the product from being contaminated with bacteria.

② The sealing gaskets are made of high temperature resistant polytetrafluoroethylene composite. (Maximum temperature ≤120℃)

③ Sealing gasket, valve body middle sealing ring, valve stem packing are all made of high quality polytetrafluoroethylene material. Long life, corrosion resistance, ensure no internal and external leakage.

④ Streamlined flow channel, so that the pressure loss is small.

⑤ The gasket can be replaced, more convenient to disassemble, and low maintenance cost.

Widely used in biological fermentation, medicine and beer fermentation, amino acid fermentation, biological pesticide fermentation, biological fertilizer fermentation, various antibiotic fermentation, biological, biochemical, chemical and pharmaceutical materials, water, steam, cold control and other fields, the bottom can be opened according to customer needs, high temperature resistance long service life, no dead Angle to reach zero leakage level.
