Q: How can a steel ball in a steel ball valve be put in?: This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.

Q: What does telescopic ball valve mean? What does it mean?: In fact, the length of L can vary within a certain range

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: Gate valve, ball valve, the difference between the pressure regulating valve: Gate valve and stop valve are shut-off valve, is the most common two valves. From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious. Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions.

Q: What does "ball pq340h-10c-1200" mean?: This is the worm gear eccentric hard seal hemisphere valve, 10 kilograms of pressure, caliber is 1200.

Q: What are the advantages and disadvantages of the two functions of the pneumatic ball valve actuator?: The working principle of the single action mode:When the air pressure from the air intake (2) between the two piston into the cylinder cavity, the two ends of the cylinder piston moves to the separation direction, forcing the ends of the compression spring, both ends of the air chamber air through the air intake (4) discharged, while making two piston rack synchronous drive output shaft (gear) counterclockwise. In the air pressure through the solenoid valve for cylinder piston to move backwards, two to the middle direction in the spring, the middle air cavity air from the air outlet (2) discharged, while making two piston rack (gear) synchronous drives the output shaft to rotate clockwise. (if the piston is mounted in opposite directions and the spring is reset, the output shaft becomes reverse rotating, i.e., single acting reverse type)

Q: It's the brass valve in front of the water meter. It doesn't move at all. It's broken. Found the following axis of rotation is not rust, copper plated iron, with a screwdriver to the ball screw, screw is not moving, the valve is much worse than PPR. Real junk products: There is a ball groove, the shaft is connected with a handle is installed in the tank, due to frequent water tap connecting parts have a certain slope groove and the shaft, causing slipping the ball still turn the handle when (the metal ball). Difficult to repair, usually replace the whole ball valve.

Q: Allowable leakage on ball valves: what does CLassVI mean?: This is the valve leakage level, level VIThe GB/T4213-92 standard specifies six grades for the valve leakage. The specific requirements are shown in the standard table. The lowest level is level I, without specific requirements; the highest level is grade VI, i.e., the bubble grade.

Q: Valve and ball valve is the same thing? Don't know don't speak: Ball valves belong to a large class of valves, valves include gate valve, butterfly valve, check valve, globe valve, ball valve, trap valve, safety valve, etc. all valves

Q: Under what circumstances with the butterfly valve, under what circumstances with the ball valve?: Selection principle of ball valve:1, oil, natural gas transmission mains, need to clean the pipeline, and be buried in the ground, all pass by, the ball valve full welded structure; buried in the ground, select all pass through ball valve welded connection or flange connection; pipe flange connection, welding, selection of connection, all pass through or shrink the diameter of the ball valve.2, product oil pipeline and storage equipment, choose flange connected ball valve.3, the city gas and natural gas pipeline, choose flange connection and internal thread of the floating ball valve.1 、 in the oxygen piping system of the metallurgical system, the fixed ball ball valve should be selected after the strict degreasing treatment and the flange connection.2, low temperature medium piping system and device, should choose to use the valve cover of low temperature ball valve.3 、 the lifting rod type ball valve can be used on the pipeline system of the catalytic cracking unit of the oil refining unit.4, chemical systems such as acid and alkali corrosive media and piping systems, it is appropriate to choose austenitic stainless steel, PTFE seat sealing ring for all stainless steel ball valve.5 、 metal to metal sealing ball valve can be used in metallurgy system, power system, petrochemical equipment, piping system or device of high temperature medium in city heating system. 6, the need for flow regulation, you can choose the worm gear drive, pneumatic or electric with V shaped opening of the regulating valve.

Our company is specialized in the production of a series of products, such as knife style gate valves, various types of metal hard sealed ball valves, PTFE soft sealed ball valves, high temperature and pressure wrought steel ball valves, eccentric semi-spherical valves and three way valves (T-pattern, Y-pattern and L-pattern), which are designed and manufactured according to international standards, like GB, ANSI/API, JIS and DIN. The main body materials of valves are LCB and LF.
