Q:Water purifier water PE pipe and copper ball valve with lock nut connection reliability, and interface size requirements.
After the impact, for a period of time, PE pipe cracking phenomenon, this is what causes? This is connected to the tap water.Chasing the answerWhere is it cracked?!
Q:1 and 1/2 ball valve is how much?
1 and 1/2 ball valves, 1 and 1/2 are the international imperial units of length, which refer to the length, length, or size of the valve through the bore, approximately 38.1mm
Q:What does 1000WOG mean on a ball screw valve?
It's also a standard, huh?
Q:What does "q341" and "q347" mean?
Valve type explanation:Q stands for ball valves;3 represents worm gear drive;4 represents flange connection;1 represents straight through floating ball, and 7 represents straight through fixed ball.Therefore, Q341 is a turbine driven flange straight through floating ball valve, Q347 is a turbine drive flange through fixed ball valve.
Q:1 piece, 2 piece, 3 piece ball valve, which places are used in large quantities?
Three piece ball valve has the following advantages:1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.2., simple structure, small size, light weight.3., close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
Q:The difference between a cricket valve and a constant pressure valve
Ball valve for ball ball column shape and called, is mainly to be closed, and often switch when the fluid flow control to throttle function and design, is the main characteristic of effective throttling, to minimize and reduce the phenomenon of drawing valve and valve seat dip (wash) inhibition, but because of the seat is parallel to the line, change the flow of fluid through the valve seat will be in class.
Q:What is the difference between floating and fixed ball valves?
Fixed ball valve is the ball with the lower stem fixed, pressure will not produce movement, therefore, in the design, two sealing ring must have sufficient preload to ensure that the valve seat and sphere seal, is a two sided forced seal. Thrust or sliding bearings are usually provided on the upper and lower stems of the ball.
Q:What do you mean by 266 in the 266 brass ball valve?
In order to consider the cost, some manufacturers put in different environment in accordance with the actual need in addition to the basic properties (such as gas safety requirements, key strength, air conditioning temperature, focus on material and penetration, ordinary water can have the basic properties, can economic production and product classification), but in the national standard of the same specifications or inside them the same type,
Q:What does "F" and "C" mean in the Q11F-16C of the ball valve?
This model is not international standard number, but still can see, of which, F refers to the sealing material: fluorine plastic, C refers to the body material: carbon steel.
Q:Why is there a water or oil in the new ball valve?
The test has leaked;Pressure test, lubrication ah!
