Wuzhong instrument two-position five-way solenoid valve characteristics

The control valve, also known as the control valve, is a device in the field of industrial automation process control that uses power operation to change the process parameters such as the flow, pressure, temperature, and liquid level of the pipeline medium.

1. The human element Because of the errors caused by human elements, including misreading, miscalculation and parallax. Misreading often occurs in measuring tools such as vernier rulers and centimeter cards. The vernier scale is likely to misread a small reading, such as 10.02 mm or 9.98 mm at 10.00 mm. Divide...

The correct use of thermocouples can not only accurately obtain the temperature value to ensure that the product is qualified, but also save the data consumption of thermocouples, which can not only save money but also ensure product quality. Incorrect devices, thermal conductivity and moment lag are the first errors in the use of thermocouples.

(1) The conditioning valve belongs to the on-site dashboard, and the regular working temperature should be in the range of -25-60 °C, and the air humidity should be ≤ 95%. If it is installed outdoors or in a high-temperature place, moisture-proof and temperature-reducing measures should be used. In areas where there is an epicenter, it is necessary to eradicate the source of vibration or improve vibration isolation measures. ...

Pneumatic butterfly valves are usually composed of a combination of pneumatic actuators and valve bodies and some accessories after debugging. This article first introduces the precautions for the on-site application of pneumatic butterfly valves. 1. The control cabinet sends a signal that the valve does not move, and the pneumatic conditioning butterfly valve is in the device locator after on-site investigation.

1. According to the use occasion and use of the valve, confirm the driving method: manual, electric, pneumatic, and hydraulic. 2. Selection of manual methods: The standard of ball valve and butterfly valve "DN150 can be driven by a handle; Standard DN200 should be used to drive worm gearbox. b. Gate valve ...

The normal operation of the appearance is inseparable from the protection of the site, especially some important process links, once there is a leak, it will greatly affect the quality of the product, resulting in heavy losses. First of all, on important tanks in general ...

1. The valve core is pressure balanced, even if the large-diameter valve is under the high pressure drop parts, it can also be operated with a smaller actuator. 2. The inner cavity of the valve is straight-through streamlined, which greatly reduces the activity resistance. 3. The concentric movement method of the valve core and the valve body is greatly ...

1. Before the equipment, you should carefully read the operation manual of the product, check whether the product can fully meet the application needs, understand the key to the equipment, and prepare for the operation. 2. Check whether the parameters marked on the nameplate can be the parameters of the selected product and whether they can be consistent with the instructions. 3. Acceptance ...

The valve is a control component in the fluid transportation system, which has the functions of shut-off, conditioning, diversion, preventing backflow, stabilizing pressure, diverting or overflowing pressure relief. Valves for fluid control systems, from the simplest shut-off valves to the most chaotic valves used in automated control systems, range from ...

Double-seat cast ball angle valve The nominal diameter is 40-200 mm Nominal pressure ANSI 125, 150, 300, 600JIS10, 16, 20, 30, 40K PN1.6, 4.0, 6.4MPa Connection type Flange...

Knife gate valve is a kind of valve, which is called knife gate valve because of its different structure. It has outstanding circularity through the use of some special media, such as some viscous media, granular media, etc. It solves some of the problems of modern equipment and becomes an indispensable component of modern equipment ...

Valve application requirements (1) General gate valves, ball valves, and globe valves are prohibited from dispatching according to their structural characteristics. However, in process design, it is widely used for mediation. Because of the scheduling application, the valve seal has been in a throttling state for a long time, and the impurities in the oil have washed the seal, endangering the seal.

Scientific and technological innovation, Wuzhong Instrument has gone through a road of deep integration of informatization and industrialization. "There are too many foreign 'stuck neck' technical products. The control valve industry is all-encompassing, with 100,000 varieties and specifications, more than 1 million parts, and more than 5,000 quality control points.

In all kinds of mechanical connectors, the anti-loosening of bolts is a very important link. So can the tension spring washer be loosened? The principle of anti-loosening of the tension spring washer The anti-loosening principle of the tension spring washer is that after flattening the tension spring washer, the tension spring ...

The mechanical deflection angle of the movable part of the surface can be measured and converted, and the size to be measured is directly indicated by the indicator, so it is also called the direct-reading appearance. According to the working principle, the indication appearance can be divided into magnetoelectric ...

1. Glander type This is the form that is used a lot. The same form can be different in many details. For example, in terms of hold-down bolts, it can be divided into T-bolts (for low-pressure valves with a pressure of ≤ 16 kg/cm²), stud bolts and loose joints. From the gland point of view, it can be divided into integral and ...

1. Elastic ball valve (i.e. orbital ball valve) The elastic ball valve is the orbital ball valve, and its ball is elastic. The ball and the seat seal ring are made of metal materials, and the specific pressure of the seal is very large, and the pressure of the medium itself can not meet the requirements of the seal, so it is necessary to apply external force. This...

1. Units and scales (scales) The scale (scale) unit of the temperature gauge is the Celsius temperature (°C). 2. Detect (measure) the penetration length of the element The length of the penetration should be selected in such a way as to insert the detection (test) element ...

From the perspective of product application, hard seal ball valve defects can be roughly divided into the following two categories: non-technical faults and skill defects. The following text mainly introduces the analysis and solution of non-technical problems of hard seal ball valves; ...
