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:What's the difference between T ball valve and L ball valve?
This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.
Q:Is the ball valve installed in a direction?
Valve installation generally no direction required, any end of the valve can be mounted on the upper end. If the valve marked the direction, then it should be installed in the direction of tagging installed.
Q:One stainless steel ball, two pieces, three pieces of difference, use
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:Home tap water valve (ball valve) half open or well open, open half is not love rust live?
Open big, small, same, as long as the pressure is enough, enough flow does not matter. The effect is half open, with a sound.
Q:The working principle of the track type ball valve
No wear and tear of switch:The ball core deviates from the valve seat and then rotates, eliminates the friction of the valve seat, and solves the abrasion problem of the seat of the traditional ball valve, gate valve and plug valve.Anti friction valve hard and dense cover:The surface of the ball core is welded with a hard polished sealing surface, which can ensure the sealing performance under very severe working conditions.
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:How many points of the ball valve, corresponding to a bit valve?
No detailed conversion forms are required. How many inches is the representation of inches?.In English, 12 inches are 1 feet, 1 inches =8 cents.So: 1/2 "ball valve, =4 sub ball valve, 1/4" ball valve, =2 sub ball valve, 3/8 ball valve, =3 sub ball valve, and so on.Just a simple conversion relationship.
Q:What is an eccentric hemispherical valve? How do you understand?
The eccentric hemisphere valve and the flange gate valve belong to the same type of valve. The difference is that the closing piece is a sphere, and the ball rotates around the center of the valve body to open and close a valve.
Q:Structure design principle of fire ball valve
The purpose of fire protection structure design of valve seat is:(1) effective guarantee in the fire accident, the upstream pressure medium as little as possible into the body cavity through the valve seat, thereby causing internal leakage and leakage. Ensure that fire accidents are not expanded by fire before the firemen arrive at the scene of the accident. After the firemen arrive at the scene, fire equipment can be used to quickly suppress the fire and eliminate fire accidents.(2) to make the structure of the product meets API6D specifications. Fire proof can be obtained through fire test.Fireproof design of valve seat:Set graphite in metal fire valve seat and valve body sealing rings; sealing set fireproof metal in the metal valve seat and ball room. The structure is shown in Figures 1 and 2.
