Ball valve opening and closing pieces as a sphere, the use of the ball around the axis of the axis of the rotation 90° achieve the purpose of opening and closing. Butterfly valve opening and closing parts are circular disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening and closing. Gate valve opening and closing of the gate is to rely on the gate, through the rotation of the hand wheel to drive the valve stem rotation, so as to achieve the purpose of opening and closing. The valve opening and closing parts are plug shaped valve, the sealing surface is plane or cone, flow direction of medium to low prices. Check valve opening and closing parts by the medium flow and power to open or close, is an automatic valve to achieve the prevention of the medium. Control valve with the power to change the flow of media, pressure, temperature, liquid level and other process parameters of the final control element. Solenoid valve used to control the flow of the basic elements of automation, through power off to achieve the solenoid valve to open or close the role. Safety valve to rely on the pressure of the medium itself automatically open the valve, when the pressure exceeds a certain value of the container to start emissions. Valve is the use of control valve in the valve body to open and close the valve to adjust the flow of the medium, the medium pressure to reduce. Traps steam system in the condensation of water, air and carbon dioxide gas as soon as possible, so as to achieve energy-saving effect. Needle type valve is an important part of the instrument measuring piping system, its function is to open or cut off the pipeline medium fluid. Diaphragm valve opening and closing parts is a piece of soft material made of the diaphragm, the valve body cavity and valve cover chamber and drive components separated. Discharge valve is mainly used in the reaction kettle, storage tanks and other containers of the bottom of the discharge, discharge and no dead zone off operation. Exhaust valve is applied to the independent heating system, central heating system, central air-conditioning system, such as the role of exhaust gas. Breathing valve is generally used in atmospheric pressure or low pressure tank, he can not breath, inhale, ensure constant pressure system. Angle seat valve is the automatic control system of common pipe line switch, through 7 to 4 kg gas source pressure to open or close the valve. Balance valve is a very special feature of the valve, in the hydraulic conditions, play a dynamic or static balance adjustment valve. Mud Valves are arranged in the bottom wall of various types of sedimentation tank to remove the mud and sand from the bottom of the pool, and have no sports wear and long life. Cut off valve is one of the important accessories in the gas pipeline, when the instrument detects the gas leak, automatically shut down automatically. Filter is to remove a small amount of solid particles in the liquid small equipment, can protect the normal operation of the equipment, easy to assemble and disassemble. The flame arrester is used to prevent the gas, the flame spread of the liquid and the safety device for preventing the explosion caused by tempering. At the end of the valve installed in the bottom of the pump suction pipe, automatically prevent fluid backflow. Valve device for energy saving. The mirror can observe the liquid, gas, steam and other media flow reaction in the pipeline at any time. Hydraulic control valve is composed of a main valve and attached to the catheter, guide valve, needle valve, ball valve and other components, can be installed horizontally.
