In order to ensure the disc can often to the seat to the appropriate location, in disc preset hinge agencies, in order to have enough plug valve kai xuan space, and true, all aspects of the valve and valve seat contact. Swing check valve with the humble hinge institutions, there is a door the same disc freely on heel seat appearance. The check valve inside will belong to this type of valve, it covers the swing check valve and up and down type check valve. Through the up and down as the valve is in the same way, fluid type check valve of the channel is narrow, because this after check up and down type Marine valve pressure drop than the swing check valves are bigger, and swing check valve flow limit rarely. Up and down type check valve disc is located in the body seat tightly closed surface. All disc can be made from metal, can also be embedded in the metal, animal skins, while the use of synthetic rubber or thought fit to cover surface, the decision on the use of performance requirements. Swing check valve in the absolute open state, the fluid pressure is almost not affected by blocking, because of the pressure drop through the valve is relatively small. Apart from this check valve can be freely up and down, the remaining local is like by the valve in the same way, the fluid pressure from the valve seat tightly closed surface lift, medium return cause disc to seat, flow and truncation. 。 According to the conditions of use, Industrial Valves can be all-metal structure, and can be embedded in disc shelves rubber, rubber mat or rubber ring. General office of the valve is semi-automatic, flow in one direction under the effect of fluid pressure, valve open; In the opposite direction of fluid flow, the fluid pressure and the disc from the overlap of disc utility in the seat, so blocking flow. Q: office principle of check valve in the multiple-choice answer: check the office of the utility of the principle of product type of valve is only allowed to medium flows in one direction, the direction and stop the flow. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
