The use of the grooved pneumatic valve specifications

select pneumatic groove gate valve must contact with its actual needs and place before the fulfillment of the characteristics of the resolution to choose pneumatic groove gate valve, choose the reasonable use pneumatic valve is a scholarship, pneumatic valve disc groove gate device in the direction of the diameter of the pipe.
select pneumatic groove gate valve must contact with its actual needs and place before the fulfillment of the characteristics of the resolution to choose pneumatic groove gate valve, choose the reasonable use pneumatic valve pneumatic valve pneumatic valve is grooved gate groove gate a scholarship, pneumatic valve disc groove gate device in the direction of the diameter of the pipe. In cylindrical channels of pneumatic valve pneumatic brake valve body and disc disc around the axis of rotation, rotation between viewpoint is ° ~ °, rotate to °, the pneumatic valve is fully open.
brake pneumatic valve brief layout, small volume, light weight, only by a few parts. And just ° rotation can be rapidly opening and closing, the operation is a brief, together with the pneumatic valve pneumatic valve groove groove gate lock pneumatic valve is controlled by the outstanding fluid properties. Brake pneumatic valve in open position, the butterfly plate thickness is medium flows through the resistance of the pneumatic valve body only, so by what happens to the pneumatic valve pressure drop is small, so it has good flow control characteristics. Brake pneumatic valve seal and metal sealing machine has two sealing type. Elastic sealing pneumatic valve, sealing ring to be set on the pneumatic valve body or attached to the butterfly plate peripheral.
choose metal sealing pneumatic valve usually last longer than elastic sealing pneumatic valve, but it is hard to be completely sealed. Metal sealing can adapt high working temperature, elastic seal has disadvantages under the constraint of a temperature.
if demand brake pneumatic valve as a pneumatic valve pneumatic valve flow groove gate groove gate volume control is used, the first is the correct choose the size and type of pneumatic valve. Brake layout principle of the pneumatic valve is particularly suitable manufacturing large diameter pneumatic valves. Pneumatic groove gate valve not only in the oil and gas, chemical industry, water disposal industry widely used normally, and also used in cooling water system of thermal power plants.
the brakes used pneumatic valve with pneumatic clamp gate valve and flange brake pneumatic valve two kinds. Wafer brake pneumatic valve pneumatic valve is in the stud connection in place between two pipe flanges, the flange type brake is pneumatic valve pneumatic valves with flange, bolts on the pneumatic valve flange connection on the pipe flange on both ends.
the strength of the pneumatic valve function refers to the pneumatic valve can accept medium pressure. Pneumatic valve is to accept internal pressure of mechanical products, it is necessary to have sufficient strength and stiffness, in order to ensure the long-term use without rupture or deformation occurred.
grooved pneumatic valve pneumatic brake valve stem for the bar layout, through conditioning treatment, outstanding comprehensive mechanics function and corrosion resistance, abrasion resistance. Brake pneumatic valve open/close the pneumatic valve stem make rotation movement up and down and run, not only of the pneumatic valve stem packing is not easy to damage, seal. With butterfly plate fixed cone pin, overhanging end to prevent rushed out of the plan, to avoid cracking in pneumatic valve stem and disc joint accident when the pneumatic valve stem collapse.
