1. Introduce manual hose valve hose valve valve head is an elastic body and the elastomer body can through an agency or process fluid pressure and being pushed together, or called & other; Compact & throughout; 。 In most cases, the elastomer is a simple line within the whole flow channel as well as the complete bushing flange. Bushing separate layer all the moving parts and logistics, so did not contact with the three-dimensional parts can be made of cheaper materials, such as carbon steel manufacturing. Because the logistics by planning the set of all inclusive, so such increase again don't need the benefit of the stuffing box. When hose Industrial Valves bushing seal, the sealing is widespread, and for most of the other valves is a simple seal point. Due to the characteristics of large objects or grain can accommodate in valve sealing area, and remained sealed. For this reason, hose valve can be ideal for fluid including particle or pulp, such as the food industry, sand water system, sewage treatment, the process water, grain logistics, etc. Due to resilience associated with elastomer liner bushing effectively resist the due to solid particles through wear and tear. According to the material selection of bushing at the same time, special rubber hoses, can very good use those or medium corrosion on the surface of the metal. Hose valve's main limitation is due to the limitation of elastomer liner temperature and pressure, he can only be used for low pressure operation. Because the average bushing materials ( The fourth sodium fluoride, neoprene, butyl rubber - N and fluorocarbon rubber) Also involves the rubber hose, rubber hose used for hose valve pressure rating instead of the normal pressure rating of the valve. Although elastomer pressure level is low, single by the use of special liner or body structure can improve the pressure limit. For example, using the rubber of rubber bushing with metal net, within or around the bushing (such as a kind of external fluid Pressure) To offset the logistics operation pressure and increases the pressure limit. Another limitation is that when the valve is in open position, if the pressure inside the process system to the vacuum to move or produce high pressure drop, unless the bushing is actually installed outside the closed element, the bushing will be crushed, hose Industrial Valves in pulsed logistics work is also poor, because bush often lead to premature damage of expansion and contraction. When hose valve used for liquid operation, there must be some fluid motion, due to the large seal area of the bushing fluid displacement. In addition to the performance of incompressible fluid make the bushing produces additional strain and bushing instability. For logistics straight through without interference, hose valve pressure drop is small or not, can open - ideal for Close operation. Because they are often used in low pressure operation, so they are easy to throttle and provide good flow control at 50% until the last trip. Knowledge because of smooth wall bushing and resilience and early know 50% minimum, to avoid using the whole trip is invalid. For very abrasion condition ( Especially for sharp particles) , recommend the side is not near the throttling Industrial Valves closed, because the grain to corrosion bushing and can lead to potential column groove. Bushing of peace and stability on the other hand, is it smooth wall flow to produce minimum turbulence or pipeline vibration. Resilience bushing can also easily get bubble tight closure. Most of the hose valve is after such as pressure of air or other liquid or use manual operation methods of manipulator to wake. They could also be used as a control valve automation. Hose valve 2 ~ 12 (in common size (12) And ANDI150 level ( PN16） 。 2. Manually hose valve design two kinds of structure of common rubber hose valve body is open and closed valve body, open body no metal hose valve body shell, relying instead on a metal structure of shares. Share price structure has two rail fastening on the flange metal stents. Flange metal stents design into two half, so that the rubber bushing China yu between flange support during installation. At the top and bottom bracket used for connecting rod or 1/2 of the flange into a structural unit. At the top of the scaffold with a thread to send to catch up with the wheel. Stem has a freedom of movement joint is connected to the movement of the closed element, it is called a compressor. It stands above the liner directly, when the hand wheel rotation, compressor downward movement, and to the bottom bracket extrusion sleeve. Start the body structure is simple, don't need expensive metal castings, bloating, leakage of the lining sleeve for the funeral and inspection, tear, or other accidents. This structure are the main disadvantages of bushing is exposed to the external environment is bad, it will shorten the life of bushing. Enclosed hose valve have most of the flow through the valve appearance. But the body is not a true body and would rather say it is a bushing protection shell. Closed institutions similar to start hose valve body design, the difference is compressor is completely closed on liner inside of the valve body. Can be designed into a whole body casting rod into the bottom of the appearance, the logistics and perpendicular to the layer, its role as the static sealing bar.
