Electro-pneumatic valve IP waterproof class code pneumatic valve operation mode

Electro-pneumatic valve waterproof grade operating system is to classify electrical appliances according to their characteristics of anti-fouling and waterproof.

The so-called external objects here contain special tools, people’s fingers and so on are not allowed to touch the electric parts of the electrical appliances, in order to prevent electric shock accidents.
The waterproof level is composed by numbers. The first number represents the level of dust removal and foreign object intrusion avoidance of the actuator, and the second number represents the sealing degree of the actuator to prevent internal moisture and moisture-proof intrusion. The more data, the higher the safety protection level.

The waterproof level is composed by numbers. The first number represents the level of dust removal and foreign object intrusion avoidance of the actuator, and the second number represents the sealing degree of the actuator to prevent internal moisture and moisture-proof intrusion. The more data, the higher the safety protection level. Expresses the solid state safety protection: Safety protection category indicates no safety protection, no special safety protection for external people and objects, avoid the intrusion of solid foreign objects with aperture over 50mm, avoid the body (such as palm) due to accident and contact with the internal parts of electrical appliances, Avoid the intrusion of foreign objects with relatively large specifications (aperture more than 50mm). Avoid the intrusion of solid foreign objects with aperture more than 12mm. Avoid human fingers from touching the internal parts of electrical appliances. A means to avoid intrusion of medium level specifications (aperture over 12.5mm) to avoid intrusion of solid objects over 2.5mm to avoid intrusion of solid objects over 2.5mm to avoid intrusion of aperture or wall thickness over 2.5mm, cables and similar small and medium-sized foreign objects into the internal parts of electrical appliances to avoid intrusion of solid objects over 1.0mm to avoid intrusion of solid foreign objects over 1.0mm to avoid intrusion of solid foreign objects over 1.0mm to avoid aperture or wall thickness over 1.0mm A means, cable and similar small and medium-sized foreign object invasion and contact with the internal parts of electrical appliances to avoid foreign objects and dust completely avoid foreign objects invasion, although can not completely avoid dust invasion, but the amount of dust invasion will not affect the normal operation of electrical appliances to avoid foreign objects and dust completely avoid foreign objects and dust invasion expressed the liquid safety protection: No safety protection for water or moisture in the body no special safety protection to avoid water intrusion into vertical drops (such as condensate) will not cause damage to the electrical appliance skew 15℃, still can prevent water intrusion when the electrical appliance from vertical skew to 15℃, Water seepage will not cause damage to the electrical equipment to avoid spraying water intrusion waterproof rainproof or to avoid the vertical Angle of less than 60 degrees of water intrusion caused by spraying water into the electrical equipment and damage to avoid splashing water intrusion in all directions to avoid splashing water intrusion into the electrical equipment and damage to avoid gushing water intrusion from all directions to fly out of the sprinkler head caused by water intrusion electrical damage to avoid soaking water The intrusion appliance is immersed in the water for a certain time or under a certain pressure in the following specifications, which can ensure that no damage will be caused by immersion to avoid flooding water. The intrusion appliance should be permanently submerged under the specified pressure, which can ensure that no damage will be caused by immersion. According to the control method classification can be divided into two types of pneumatic valve power switch type and regulator type. Pneumatic switch gate valve includes electric actuator, gate valve, manual operation organization, pneumatic valve solution triplet, relay, travel switch, muffler, quick plug connector, air compressor, bronchial and other parts, in which manual operation organization, travel switch, pneumatic valve solution triplet, muffler, quick plug connector can be randomly installed according to the working condition of the site. Pneumatic valve is the use of compressed gas to drive the gate valve, according to the control method classification can be divided into power switch type and regulator type two categories. Pneumatic switch gate valve includes electric actuator, gate valve, manual operation organization, pneumatic valve solution triplet, relay, travel switch, muffler, quick plug connector, air compressor, bronchial and other parts, in which manual operation organization, travel switch, pneumatic valve solution triplet, muffler, quick plug connector can be randomly installed according to the working condition of the site. Pneumatic adjusting gate valve includes electric actuator, gate valve, manual operation organization, electric-gas valve positioner, pneumatic valve solution triplings, silencer, quick plug joint, air refrigeration compressor bronchial, etc. Here manual operation organization, silencer, quick plug joint can also be randomly installed according to the working condition on the spot.
Taichen famous brand pneumatic valves are widely used in mechanical automation of water, gas, steam, sand, oil, shape memory alloy and other media. Common problems in pneumatic valve operation: first, open the valve, be sure to common problems: 1, check whether the oil drum on the gas filter pressure reducer has given oil (grease); 2, the detection pipeline is not clean; If there is dirt, it is best to modify the pipeline filter in front of the valve; 3, then on the control source; 4, and then adjust the pneumatic valve pressure; Piston machine (0.4-0.7) KG, plastic film type (0.1-0.2) KG; 5, on the switching power supply (power supply switch type for working voltage) or (adjustable type of electricity flow or voltage signal); 6, then adjust or open degree control; Two, close the valve, be sure to common problems: 1, disconnect the control signal (current voltage or current flow); 2. Adjust the working pressure of air purification to zero; Pneumatic valve operation mode: 1, the operation of pneumatic valve to open and close are according to the clockwise.
2, the worker opens and closes the pneumatic valve in the pipeline network, the opening and closing speed is not too much, even the large diameter valve must be in 200-600 revolutions.
3. In order to better operate the opening and closing of the pneumatic valve, the opening and closing torque should be less than 240N-m in the case of hydraulic and electrical pressure.
4. The opening and closing operation end of the pneumatic valve should be square tenon, and the size should be standardized, and toward the road surface, so that the operator can operate directly on the ground.
Valve bodies with turntables are not suitable for underground pipe networks.
5, in order to do not open and close too much, the pneumatic valve opening and closing level scale, should be conspicuously forged in the transmission cover tight or change the direction of the indicating disk shell, are facing the road.
When the opening and closing adjustment is accurate, it should be bolted.
6. The opening and closing operation of the pneumatic valve in the pipeline network is not suitable for well work.
If the operating mechanism of the pneumatic valve and the indicating plate is about 1.5 meters lower than the road surface, a firm and firm extension rod equipment should be set up to facilitate the operator to observe and operate on the ground.
