PPR Ball Valve To Overcome The Deformation Of Rubber To Achieve

What is a PPR Ball Valve? What is a globe valve? What is the difference between the two? PPR tube in the cut-off valve is a plug-shaped disc, sealing surface was flat or cone, the valve along the center line of the fluid for linear motion. The movement of the stem, there are lift rod (stem lift, hand wheel does not lift), there are lifting and rotating rod (hand wheel and stem together with the lift, the nut is located on the valve body). The globe valve is only suitable for full and full clearance and is not allowed to be adjusted and throttled.

PPR Ball Valve in the opening and closing process is subject to both sides of the valve seat under the force of the operation, it is more than the half-PPR Ball Valve opening and closing torque, the greater the diameter of the larger opening and closing torque difference is more obvious, butterfly valve opening and closing is to overcome the deformation of rubber To achieve, more torque. The gate valve, cut-off valve operation time is long and strenuous. The following are the same as the "

PPR Ball Valve and plug valve is the same type of valve, only its closure is a sphere, the sphere around the center of the valve body for rotation to open, close a valve. PPR Ball Valves are mainly used in piping to cut, distribute and change the flow direction of the media.

1, high temperature, high pressure medium pipe or device should use the cut-off valve.

Such as: thermal power plants, nuclear power plants, petrochemical system of high temperature, high pressure pipeline.

2, the pipeline on the flow resistance on the strict management of the pipeline.

Such as: the pressure loss is not considered much place.

3, small valve can choose needle, instrument valve, sampling valve, pressure valve and so on.

4, there are flow regulation or pressure regulation, but the regulation accuracy is not high, and the pipe diameter is relatively small, such as the nominal through the ≤ 50mm on the pipeline, should use.

5, synthetic industrial production of small chemical fertilizer and large chemical fertilizer should use the nominal pressure pn160 nominal pressure 16mpa or pn320 nominal pressure 32mpa high pressure angle type ppr cut valve or high pressure angle throttle.

6, alumina Bayer production in the desilicon workshop, easy to coke on the pipeline, easy to use the valve body separately, the seat can be, the carbide seal of the DC-type ppr cut valve or DC throttle.

7, urban construction in the water supply, heating works, the nominal through the smaller pipelines, optional cut-off, balance valve.
