Q:What's the difference between a one piece ball valve and a two piece ball valve?
A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
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:Is the ball valve the same as the float valve?
Ball valve and float valve is a kind of valve, the ball valve is a valve inside the ball, it is called the ball valve
Q:The difference between cut-off valve and ball valve in PPR
Yes, now the globe valve is more than the ball valve with more people, and its main or cut-off valve, a lot of adjustability, and most can be universal.Specific differences are as follows:Valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Stem movement in the form of lifting rod (stem lifting, hand wheel not lifting), but also lifting, rotating rod type (hand wheel with the valve stem to rotate up and down, nut on the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.The cut-off valve is a forced seal type valve, so when the valve is closed, the valve must be applied to the pressure, to force the sealing surface is not leaking. When the medium into the valve six from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault. In recent years, the emergence of self sealing valve, globe valve replaced by medium flow on the top of the valve into the valve chamber, then in the medium under pressure, the valve off a small force, and force open the valve, stem diameter can be reduced accordingly. At the same time, in the role of media, this form of valve is also more stringent. China's valve "three to" has stipulated that the flow direction of the cut-off valve should be top-down.
Q:Where to buy the ball valve?
Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight. Ball valve is the most suitable switch, cut off the use.
Q:PPR gate valve, stop valve, dark valve, ball valve what is the difference between the gate valve and dark valve is a thing?
Gate valve in general, over the water, the cut-off valve is generally in the air, the ball valve over the water will do, the valve is divided into open bar gate valve, dark rod gate valve, you say the dark valve should be dark rod gate valve
Q:3/43/8 above the ball valve is not usually said of the big ball valve?
Ball valve above the 3/4, 3/8, refers to the ball valve connector, thread connection water pipe diameter, 3/4, 3/8 is the pipe diameter of the British size, 3/4 is 6 in charge, equivalent to 19.1 mm diameter; 3/8 is 3 in charge, 9.5 mm. Of course, the larger the ball valve, the greater the diameter.
Q:What is the force distance of a ball valve with a diameter of 150mm?
Reference: ball valve 1000N on the line, butterfly 250N canThis valve with the switch torque is related, each manufacturer according to the workmanship, process switching torque is not the same.You can refer to the recommended value of the actuator manufacturer
Q:3/4 on the elbow of the water pipe. How about that ball valve?
3/4 inches converted approximately equal to 20mm, that is, DN20, can be equipped with DN20 caliber ball valve, commonly used for brass material
Q:How much pressure DN65 ball valve?
16-40 is normal pressure. How much pressure do you want?
