Product description of Direct Mount Ball Valve
High platform ball valve is a relatively new type of ball valve. It has some unique advantages of its own structure, such as no friction on the switch, uneasy wear on the seal, and small opening and closing torque. This will reduce the size of the actuator. Coupled with a multi turn electric actuator, the medium can be adjusted and cut off tightly. It is widely applicable to petroleum, chemical industry, urban water supply and drainage and other working conditions requiring strict cut-off, High platform direct mount ball valve is composed of flange/thread/weld high platform direct mount ball valve and ISO 5211 mounting pad for manual,electric or pneumatic actuator. High platform direct mount ball valve is ideal for any water type of environment,such as waste water, industrial or commercial use, chemical, petro and oil industries and services.
Features of Direct Mount Ball Valve
1. There is no friction when opening and closing. This function completely solves the traditional problem of affecting sealing due to mutual friction between sealing surfaces.
2. Top mounted structure. The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce the shutdown of the device and reduce the cost.
3. Single seat design. The problem that the medium in the cavity of the valve affects the safety of use due to abnormal pressure rise is eliminated.
4. Low torque design. The valve rod with special structure design can be easily opened and closed with only a small handle.
5. Wedge seal structure. The valve is sealed by pressing the ball wedge onto the valve seat with the mechanical force provided by the valve stem, so that the sealing performance of the valve is not affected by the change of pipeline differential pressure, and the sealing performance is reliably guaranteed under various working conditions.
6. Self cleaning structure of sealing surface. When the ball leans away from the valve seat, the fluid in the pipeline passes evenly along the sealing surface of the ball at 360 °, which not only eliminates the local scouring of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface, so as to achieve the purpose of self-cleaning
Working Principle of Direct Mount Ball Valve
A. Opening process
1. In the closed position, the ball is tightly pressed on the valve seat by the [wiki] mechanical [/wiki] pressure of the valve stem.
2. When the hand wheel is turned counterclockwise, the valve rod moves in the opposite direction, and the angular plane at the bottom makes the ball disengage from the valve seat.
3. The valve rod continues to lift and interacts with the guide pin in the spiral groove of the valve rod, so that the ball begins to rotate without friction.
4. Until it reaches the full open position, the valve rod is lifted to the limit position, and the ball rotates to the full open position.
B. Closing process
1. When closing, rotate the hand wheel clockwise, and the valve rod begins to drop and make the ball leave the valve seat and start to rotate.
2. Continue to rotate the handwheel, and the valve rod is affected by the guide pin embedded in the spiral groove on it, so that the valve rod and the ball rotate 90 ° at the same time.
3. When it was about to close, the ball had rotated 90 ° without contact with the valve seat.
4. During the last few turns of the hand wheel, the angular plane at the bottom of the valve rod mechanically wedges the ball to make it tightly press on the valve seat to achieve complete sealing.
It is also widely used as a regulating and intercepting device on the pipelines of SO2, steam, air, gas, ammonia, CO2 gas, oil products, water, salt water, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media in chemical, petrochemical, smelting, pharmaceutical, food and other industries.
