  • Analysis on the problems existing in China's valve industry in 2014
    At present, there are still some problems in China's valve industry. For example, China's valve enterprises are mainly low-level, small-scale and family workshop type enterprises. In terms of products, due to repeated investment and insufficient technology import, the leading products of China's valve enterprises are still low-quality mass products. It is understood that at present, all kinds of valves produced by enterprises in our country have some disadvantages, such as leakage, leakage, low appearance quality, short life, inflexible operation, and unreliability of valve electric device and pneumatic device. Some products are only equivalent to the international level in the early 80s of last century, some of the high temperature, high pressure and key equipment needed Valves are still dependent on imports

  • Common failures and preventive measures for automatic valves
    Fault one: the valve is not through. The reasons are as follows: (1) the control channel is blocked by the sundries (the passage is small and easy to be blocked); and the piston is stuck in the highest position because of rust stains; although the upper part is stressed, it can not move down and can not open the main channel. Therefore, before the piston pressure relief valve must be installed filters, for newly installed or long-term discontinued pressure relief valve, must be disassembled for inspection and cleaning.

  • How to install stainless steel valves
    1, when the valve is lifted, the rope should not be tied to the handwheel or stem, so as not to damage the components and should be tied to the flange. 2, before installation, the valve should be checked to check the specifications and types, identify damage, especially for stem. It also needs to rotate a few times to see if it is skewed, because the most easily inclined stem is in the transportation process. And remove the sundries in the valve.

  • Causes and elimination of valve stem leakage
    When the ball valve is used, the valve rod leakage often occurs. It is necessary to find the reason for the leakage of the valve stem according to the specific conditions, so as to eliminate the failure and ensure the ball valve to be used normally. If the pressure of the pipe is too high and the ball valve stem leakage is caused by the pressure range of the ball valve, the ball valve must be replaced, and the ball valve is selected to meet the pressure of the pipe to ensure the normal operation of the pipe and the related equipment.
