FAQ

The hot water pipe ball valve what brand alone?
Such as the bathroom taps are generally alternating hot and cold water, will be pulled out from the faucet two hoses, and then connected to the wall, embedded in the wall of the interface is angle valve. Because the heating pipe at the corner of the shape of 90 degrees angle, and the ball valve is straight through, so the basic difference between angle valve and spherical valve is that the angle valve exports and imports into 90 degrees right angle. rn usually angle valve mainly plays four roles: rn transfer within rn out nozzle; when the water pressure is too large, can be adjusted in the triangle valve above, turn down; the rn with switch function, if the leading Water Leakage phenomenon, can promptly put the triangle valve off, instead of the total valve closed in the home.
What's the advantage of using an electric ball valve?
Shanghai power code solenoid valve on the official website introduced the benefits of four point electric ball valve, 1. for two cutting, adjusting the occasion. 2., electric ball valve can be achieved on the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanks and other transport pipeline cutting off the medium and circulation. 3., good sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing, and even cut off. 4. 、 electric valve is small, light weight, big thrust, powerful function, servo amplifier built-in, easy to operate, high reliability.
For example, how many sizes and pressures are used in the two piece?
First of all, the difference between a ball valve and two chip, three chip ball valve is a ball valve flow, the internal structure of the necking design belongs to the design, the same diameter ball valve products must be smaller than the other two kinds of ball valves flow more. Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.
DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?
3, the flange of the same caliber and cavity size, the premise is to ensure the gate open without collision resistance, but the size and thickness of screw and the number can be determined with reference to the parameters of the same diameter flange. Finally, the point is that in mechanical design, as long as the design is reasonable, there is nothing right or wrong, but it is possible that a design will be more appropriate.
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.
1 piece, 2 piece, 3 piece ball valve, which places are used in large quantities?
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.
What are the differences and advantages between O ball valve and V ball valve?
5, high reliability1, the ball and valve seat a pair of sealing pairs, there will be no abrasions, rapid friction and other failures;2, stem into the built-in type, to eliminate the stem under the action of fluid pressure may be caused by the packing gland release flying accident hidden trouble;3 、 adopt antistatic and fireproof structure ball valve, which can be used to transport petroleum, natural gas and gas pipelinesV type ball valve structure of a right angle turn, can achieve flow regulation, according to the V type angle V type sphere, realize different proportions, V type ball valve and valve actuator and positioner supporting the use, the ratio can be adjusted V type valve adjustment for a variety of occasions, with a rated flow coefficient large, adjustable ratio, good sealing effect, regulate the performance of zero sensitivity, small size, can be vertical horizontal installation. For control of gas, steam and liquid medium.V type ball valve for rotary type rectangular structure by V type valve, pneumatic actuator, positioner and other accessories; there is a similar more than 100 of the inherent flow characteristics; dual bearing structure, the starting torque is small, with excellent sensitivity and speed sensors, the shear capacity of strong.
DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
The outer diameter of the ball valve depends on what kind of flange you useAt present, the domestic commonly used flanges are marked with JB/T (formerly mechanical industry standard), GB/T (GB), HG (Ministry of chemical industry).
