Q:What's a twin hot melt ball valve?
Is a plastic ball valve, connecting France is hot melt.
Q:What are the advantages of an air operated ball valve in comparison with other types of valves?
The thrust bearing reduces the friction torque of the stem, so that the valve stem can be operated stably for a long time.The utility model has the advantages of simple structure, small size and light weight.Convenient operation, open and close rapidly: from fully open to fully closed as long as 90 degree rotation, facilitate remote control.Easy maintenance: ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
Q:How much pressure can the flange ball valve withstand?
How many can, each kind of pressure specification has the different material quality, the thickness request, the ball valve can also use in the high pressure class.
Q:What are the inside parts of the ball valve?
The universal ball valve includes the stem, valve ball, seat, seat seal and packing.
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:What is the difference between ball valve Q41F-16C and Q41F-16P?
Ball valve Q41F-16CQ valve (Qiu represents the first letter of the alphabet), 4 representatives of 1 representative is flanged ball valve floating ball (ball valve floating ball and fixed ball, 7 ball, F fixed on behalf of) on behalf of PTFE- PTFE seal (PTFE PTFE), representing 16 of the nominal pressure valve is 16 kg (1.6Mpa). C ball valve is made of cast steel.Ball valve Q41F-16C is a soft sealed cast steel flanged ball valve
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:Pneumatic ball valve q641f-16p what do you mean?
Q is a ball of the code, 6 representative driving mode is pneumatic, 4 flanged ball valve structure is straight through channel 1 on behalf of the floating ball, f sealing surface is the fluorine plastics, 16 represents the pressure of 16 kg, P represents the body material is stainless steel, Shandong Huadian valve.
Q:What do you mean by 266 in the 266 brass ball valve?
so as to produce self number manufacturers and buyers recognition. 266 should be a category of the Le ball valve,. We do hydraulic valve production and maintenance, this problem is not corresponding, I do not know such a reasonable answer?.
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.
