Pneumatic pneumatic valve material and installation considerations

pneumatic regulating pneumatic valve is made up of actuators and regulating mechanism. Actuator is adjust the thrust part of pneumatic valve, it according to the size of the control signal pressure produce corresponding thrust, promote regulating mechanism. Pneumatic valve body is the adjustment of the pneumatic valve pneumatic control components, it is directly contact with control agent, regulating the flow of the fluid. Below small make up PARKER pneumatic pneumatic valve to do for you.

a PARKER pneumatic pneumatic valve material, PARKER pneumatic pneumatic valve body materials
PARKER pneumatic pneumatic valve should give priority to with nodular cast iron, and indicate the brand and the physical and chemical testing data of cast iron practice.
2, PARKER pneumatic pneumatic valve pneumatic valve stem material
stainless steel pneumatic valve stem, large diameter pneumatic valves should also be embedded package of stainless steel stem.
3, PARKER pneumatic pneumatic valve nut material
the cast aluminum bronze, brass or aluminum and hardness and strength is greater than the pneumatic valve stem.
4, PARKER pneumatic pneumatic valve pneumatic valve stem bushing material
the hardness and strength shall be no greater than the pneumatic valve stem, and soaking in the water condition and pneumatic, pneumatic valve stem don't form the electrochemical corrosion.
5, PARKER pneumatic pneumatic valve sealing surface material
1. PARKER pneumatic pneumatic valve have different categories, different sealing methods and material requirements;
2. Ordinary pneumatic wedge gate valve, the material of copper ring, fixed way and grinding way shall specify;
3. Soft sealing gate pneumatic valve, pneumatic valve plate rubber lining material physical chemistry and health testing data;
(4) butterfly pneumatic valve pneumatic sealing surface on the valve body material and butterfly plate must be marked on the sealing surface material; Their physical and chemical testing data, especially the health requirements of rubber, ageing resistance, wear resistance; Usually use NBR and epdm and so on, are strictly forbidden to mixed with reclaimed rubber.
6, PARKER pneumatic pneumatic valve pneumatic valve shaft packing
(1) as the PARKER pneumatic pneumatic valve in the pipe network, is usually open/close not frequent, packing in a few years no activity, the packing is not aging, long sealing effect;
2. PARKER pneumatic pneumatic valve pneumatic valve shaft packing should also be under the frequent opening and closing, good seal effect;
3. In view of the above requirements, the pneumatic valve shaft packing to lifetime don't change or more than ten years will not be changed;
(4) packing if need to change, should consider to have hydraulic pneumatic pneumatic valve design conditions change.
PARKER pneumatic pneumatic valve installation note
. PARKER pneumatic pneumatic valves open and close direction of operation, all should be clockwise closing.
。 As the PARKER pneumatic pneumatic valve in the pipeline, often artificial opening and closing, opening and closing of revolution shoulds not be too much, is the large diameter pneumatic valves should also be in - Turn in.
。 In order to facilitate a person's opening and closing operation, under the plumber pressure conditions, appropriate for N - open-close torque m。
。 PARKER pneumatic pneumatic valve opening and closing operation side shall be the square tenon, standard and size, and face to the ground, so that people can be directly from the ground. Pneumatic valve does not apply to the underground pipe network with roulette.
。 PARKER pneumatic pneumatic valve opening and closing degree of display panel
1) PARKER pneumatic pneumatic valve opening and closing degree of calibration, shall be cast on or after the transformation direction of gearbox cover plate shell, face to the ground without exception, the scale line brush on phosphor powder, as a prominent;
(2) the material of dial needle in case management better available stainless steel plate, or paint for steel plate, do not use the aluminum skin production;
3. Dial needle striking, fixation, once the open-close adjustment accurately, the rivet lock.
。 If PARKER pneumatic pneumatic valve buried deep, operating mechanism and the display panel from the ground or greater distance. M, shall be equipped with facilities of extension rod, and fixed firmly in mind, so that people from the face of the earth observation and operation. That is to say, the pneumatic valve opening and closing operation in network, is well under the homework.
