Q:What's the difference between a medium-sized ball valve and a heavy ball valve?
Medium and heavy duty difference is several kilograms, heavy material is not false, and temperature resistance, and pressure performance is better, long life!
Q:Ball valve specifications are represented by 2 FF,
FF refers to the form of connection between the valve and the pipe lineFF, or Flat Face, is a common form of flat flange connection
Q:What does "41H" mean in the ball valve Q41H-16?
Q- ball valve;4- flange connection;1- through flow channel; (structural form)H-Cr13 stainless steel; (material)16- nominal pressure; (1.6Mpa)Body material: WCB, A105This is manual, and the valve body is WCB.
Q:Can the check valve replace the ball valve?
No, but the ball valve can not replace the check valve!Ball valve is artificially to switch, the need for external force, there will be the operation is not in time, the action is not rapid, and other ills.The check valve is automatically opened and closed by hydraulic differential pressure, and the action is accurate.
Q:Is the integral type split ball valve structurally identical?
Split type ball valve, the valve body by the main body and the cover body is composed of two parts, thread connection between the main body and the cover body is arranged at the connection of the sealing ring, an annular sealing ring and ball valve, valve rod, sealing gasket, valve stem nut, a handle, a fastening nut is arranged on the main body, there is another ring the sealing ring is arranged on the cover body, interface screw holes at both ends of the valve body are respectively processed in the main body and cover body. This structure of the ball valve, the ball cavity depth is relatively shallow, the ball cavity processing is more convenient.
Q:How many kinds of ball valves are there?
Ball valves (ball valve in the field of marine engineering and ships should be cut-off valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve to rotate the valve movement.".
Q:In the wet alarm valve usually kept under working condition, alarm test ball valve state usually is closed or open?Because the alarm performance test on the pressure switch and hydraulic alarm, can be tested by open test ball valve, the bar working condition, the valve is closed or open? If so, if there is a police situation, if the police? If it does, it doesn't always call the police Seek expert advice.
The water control valve is to control the sprinkler system water supply valve opening and closing, the installation is not only to ensure the operation is convenient, but also marked the opening and closing position, its open position is determined when the sprinkler system in fire water can flow, so as to meet the requirements of the key. In system debugging after passing the system in a quasi working state, water control valve should be fully open in a normally open state, to prevent accidents and man-made shut down control valve, water control valves must be set reliable locking device to lock in the open position; at the same time also should set the signal facilities and fire control center or guard duty room connected, once the water control valve is closed should be promptly issued a warning signal, the duty should be timely check the reason and make it in the normal state. This can be seen in the sprinkler system superior acceptance specification, which is clearly explained in the provision.
Q:What is the ball valve core?
Ball valve spool is the ball, valve opening and closing parts (sphere) driven by the stem, and around the stem axis rotation. More ball material, carbon steel, forged steel, ceramics and so on.
Q:How to distinguish three points copper ball valve, two points copper ball valve
Three points, two points mean the specifications of the ball valve, three refers to the diameter of 32, two refers to the diameter of 25
Q:Must I use the ball valve for the heater?
Valve main points and angle valve, ball valve in the water pressure is large enough to use, angle valve can increase the pressure of a little water.
