[] Also called cut-off valve gate, is the most widely used of a valve! The reason it's popular is due to the process of opening and closing ① small friction between the seal faces. ② more durable. ③ opening height is not. ④ easy to manufacture. ⑤ easy maintenance. ⑥ applies not only to the low pressure valve BJ41W insulation manufacturers, also suitable for high pressure. [] The cut-off valve is closed principle is to rely on the valve bar pressure, so the valve seat sealing surface sealing surface snug fit to prevent the media circulation. Shut-off valve can only medium-way flow, directional installation. Length of the structure is greater than the valve shut-off valves, and fluid resistance, long-term operation, the sealing reliability is not strong. Thermal cut-off valve opening and closing parts of the plug-shaped valve BJ41W insulation valve price, leaving it flat or cone centerline seal, valve fluid along a straight line. Stem form of exercise with lifting rod (stem down, the hand wheel does not lift), but also lift rotating rod (hand wheel and stem rotation movements, nut located in the body). Bellows globe valves is only applicable to fully open and fully closed, does not allow for adjustment and throttle. Thermal cut-off valve is mandatory sealed valve, so the valve is closed BJ41W insulation valve suppliers, must put pressure on the valve to force the sealing surface does not leak. When the medium from the bottom of the six valve into the valve, the operating force required to overcome the resistance, the friction force and the thrust stem and packing by the pressure generated by the medium, close the valve opening force larger than the force of the valve, so that the valve The diameter of the rod to be large, otherwise the stem top corner of failures occur. In recent years, from the self-sealing valve with insulation valve, globe valve medium flow into the valve chamber to change the valve from the top, then under media pressure, the valve off a small force, and force open the valve, the valve The diameter of the rod can be correspondingly reduced. Meanwhile, under the effect of the medium, this form of valve is also more closely. China's valve "three to" has been specified, as the flow valve, should be top-down.
