Q: What is the normal temperature on the valve?: At normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees

Q: Is the valve clockwise?: The valve that can rotate is the principle of screw and nut. We can see that the switch is also buckled, so it is counterclockwise, the net is rotated out, clockwise downward, so it is off.

Q: What valve is the DN 25?: This is only the aperture of the valve. It does not represent the form of the valve.

Q: What does the valve "4" mean?: An inch of eight points, home tap, valve is generally 4 points

Q: Can other valves be used instead of 10?: An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.

Q: What is the valve before and after the pump?: Conventional setting, the pump is installed before and after the cut-off valve. As for the check valve, according to the need to decide whether to install, to see whether the occasion required to prevent backwater function.

Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?: High pressure bypass valve DN254 * 800 belongs to bypass valve.Function of bypass systemThe turbine by-pass device mainly has three functions of starting and overflowing:1 in the cold, warm and hot, the bypass system can realize the optimal unit start-up and shut-down in turbine operating conditions, start and stop curve can meet the requirements, two types of automatic and manual operation, with the establishment of the boiler steam temperature and steam turbine components. To shorten the start-up time.2. when the turbine is tripped, the bypass system can operate at a high speed and reach full open position.3., when the turbine load changes, the by-pass system has the regulating function, and the safety valve action can be avoided and the operation stability of the boiler can be improved when the instantaneous change of the moving state.The function of the bypass control valve:The main function of steam turbine bypass system is high pressure steam adjusting throttling and superheated steam cooling. The bypass valve to perform these functions at the same time and in low noise, small vibration, valve resistance to achieve its goal of temperature and pressure loss under the condition of touch.

Q: What do letters represent in the QF-2 and PX-32 valve models?: You check it on the national standard! One is accurate!

Q: What is the term "Z41H-16C" on the line?: Therefore, the opening position of the valve is determined by the position of the gate (i.e. the stroke).Z41H-16C closed, the sealing surface can only rely on medium pressure to seal, that is, only rely on the media pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.

Q: How does the valve rust die?: Valve rust, and see what material, what type, the normal model iron, small, then change it directly. Large direct buy derusting lubricants, stainless steel just, then take the acid wash
