Related Problems and Solutions of Pneumatic Ball Valve Maintenance Before Operation

  Pneumatic problems and solutions   1. Check that the valve of the pneumatic ball valve is in the fully open position   First, check that the valve of the pneumatic ball valve is in the fully open position. After completing the grease injection operation, first check whether the diameter of the valve ball is flush with the inner cavity of the valve seat. If there is a difference, adjust the open limit bolt on the actuator to ensure that the valve Fully open, otherwise, once the valve is installed, it is impossible to judge whether the carbon steel ball valve is in the fully open position.   2. Pneumatic ball valve valve cannot be injected with grease (1) When the valve shaft (rod) is being greased, the sealing pressure in the valve shaft (rod) shall not exceed 20.68MPa. Once it exceeds, check whether the grease gun is faulty and whether the outlet valve at the grease outlet of the grease gun is open.   (2) If there is no fault with the grease injection gun for ...

How Does a Check Valve Work?

Image
  1. Check valve is an automatic valve, also known as check valve, check valve, return valve or isolation valve   Check valve refers to a valve whose opening and closing part is a circular disc and acts by its own weight and medium pressure to block the backflow of the medium. The movement mode of the different types of check valves disc is divided into lift type and swing type. The lift check valve is similar in structure to the globe valve, except that it lacks the valve stem that drives the valve disc. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. Conversely, the valve is closed when the medium flows back. The check valve is often used as the bottom valve of the pumping device, which can prevent the backflow of water. The swing check valve has a disc that is inclined and can rotate around the axis, and ...

Gate Valve Vs. Globe Valve

Image
  Gate valve vs globe valve vs butterfly valve   The development of my country's economy and science and technology has been inseparable from the work of many types of equipment. For example, in the process of regulating flow, the role of valves is very prominent. With the use and development of valves, the types and models of valves have gradually increased. Gate valves and globe valves are two of the most representative products. What are the differences between gate valves and globe valves?   How gate and globe valves work Gate valve : The gate of the gatevalves moves linearly with the valve stem, which is called a lift-rod gate valve and an open-road gate valve. Usually, there is a trapezoidal thread on the lift rod. Through the nut at the top of the valve and the guide groove on the valve body, the rotary motion is changed into a linear motion, that is, the operating torque is changed into an operating thrust.   Globe valve: The valve plays an important role in ...
