Q:What is the difference between ball valve and plug valve?
Plug valves are closed or plunger shaped rotary valve, through the rotation of 90 degrees to make the valve plug on the mouth of the channel with the valve on the mouth of the same or separated, to achieve a valve opening or closing. Plug valve plug shape can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the tapered valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve lighter, but at the same time a certain loss. Plug valves are most suitable for cutting and turning on the medium and for shunting applications, but in accordance with the applicable nature and sealing surface erosion resistance, sometimes also used for throttling. As the plug seal between the movement with a wipe action, while fully open, you can completely prevent the contact with the flow medium, it is usually also used for suspension with particles of media. Another important feature of the plug valve, it is easy to adapt to multi-channel structure, so that a valve can get two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valve used, and some connecting fittings needed in the equipment.Plug valves use:Plug valves are widely used in oil production, transportation and refining equipment, but also widely used in petroleum, chemical, chemical, gas, liquefied petroleum gas, HVAC and general industries.
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:Ball valve 11F, 41F, 11H, 41H
41F flanged ball valve type sealed through using tetrafluoroethylene; 11H is threaded through valve type the alloy steel seal;
Q:What are the advantages and disadvantages of the two functions of the pneumatic ball valve actuator?
Pneumatic ball valve actuator is divided into double action and single action two modes of work.Working principle of double action mode:When the compressed air enters the middle cavity between the two pistons of the cylinder from the air inlet (2), the two pistons are separated and moved toward the two ends of the cylinder, and the air at the two ends of the air chamber is discharged through the air port (4). At the same time, the two piston rack synchronously drives the output shaft (gear) to rotate in an anticlockwise direction. On the contrary, when the air source pressure passes through the air inlet (4) into the air chamber at the end of the cylinder, the two piston moves toward the middle of the cylinder, and the air in the middle air cavity is discharged through the air port (2). At the same time, the two piston rack synchronously drives the output shaft (gear) to rotate in clockwise direction. (if the piston is mounted in opposite directions and the output shaft rotates in reverse direction, that is, double acting reverse type).
Q:How can the eccentric hemisphere valve be repaired? What are the things you should pay attention to when installing?
Standard light valve professionals to answer for you, eccentric semi spherical valve installation methods and precautions:1. Check the cleanliness of the inner cavity of the valve before installation. Make sure the parts are perfect and no foreign objects can be installed.2, ball drive device breaking up, moving and electric way two, can be installed according to user needs, valve installation before test, start and shut two times. When after a period of time, there is a leak valve, adjustable manual and electric driving device for limiting the fastening bolt due to eccentric structure, can compensate for the wear, you must read the "manual and electric drive manual adjustment".3, eccentric axis and valve seat sealing adjustment, must be experienced personnel can be carried out.
Q:The difference between globe valve and ball valve
Q:What's the diameter of the 4 point ball valve?
"4 point ball" in the "4 points" is based on the length of units per inch evolved;Divide 1 inches (25.4mm) 8, 4 points 4/8, or 1/2 inches, equal to 12.7mm.Therefore, "4 points ball valve" diameter is 12.7mm.
Q:Are ordinary ball valves standard?
DN20 caliber equivalent to3/4 inches
Q:DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
So you must first determine the pressure level of your ball valve, and then determine the valve flange used standards, and then you can determine the basic parameters of the ball valve flange.
Q:How to distinguish between single and double ball valve?
Single ball valve, pneumatic ball valve is a single short; double valve, double acting pneumatic ball valve is referred to as.Single acting pneumatic ball valve is open air, spring off; and double acting pneumatic ball valve, gas gas is closed.Single / double ball valve, is divided according to the actuator, the actuator has a single pneumatic actuator and double acting pneumatic actuator.Single acting pneumatic actuator Pneumatic actuator to more than double spring, loss of gas supply, the spring to reset actuator.For hazardous media or conditions requiring a safe position when the gas source is lost, a single action is recommended.Selection must be based on the size of the field air pressure to select the spring force, otherwise it may cause air pressure is less than overcome the spring force and can not drive the actuator.When the actuator is selected, the minimum spring force should be allowed to drive the valve normally, taking into account the gradual reduction of the spring force.
