Thermal cut-off valve opening and closing parts of the plug-shaped valve centerline leaving it flat or cone seal, valve fluid along a straight line. Stem form of exercise with lifting rod (stem down, the hand wheel does not lift) BJ41W thermal cutoff valve suppliers, 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 BJ41W, so that when the valve is closed, the pressure must be applied to 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 emergence of self-sealing 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 stem diameter can be reduced accordingly. Meanwhile, under the effect of the medium, this form of valve is also more closely. China's valve "three to" who provides Weifang valve, globe valve flow, should be top-down. Thermal cut-off valve has the following advantages 1, simple structure, manufacture and maintenance more convenient. 2, the working stroke is small, open and close a short time. 3, sealing, insulation Weifang BJ41W shutoff valve sealing surface friction is small, longer life expectancy. Disadvantages insulation cut-off valve is as follows: 1, the fluid resistance is large, a large force is required to open and closed. 2, does not apply with particles, viscosity, easy coking medium. 3. Adjust poor performance. BJ41W thermal cut-off valve supplier _BJ41W_ Valve Model Everbright Everbright Limited provided by Shandong valve. Valve Co., Ltd.
