Technical requirements for the assembly of Wuzhong instrument valves

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 ...

Load the organization The role of the loading tissue is to apply a downward loading force from the top of the pressure reducing valve. The loading structure of the FITOK pressure reducing valve is mainly the loading of tension springs. Tension spring loading has the advantage of reliability and low cost, and is the most versatile loading device in pressure reducing valves.

In the process control system, the control valve accepts the control signal of the control instrument, directly touches with the fluid, adjusts the flow of the fluid, and controls the flow, pressure, temperature, liquid level and other elements in the system, so it understands the fundamental structure and characteristics of the control valve, and selects it correctly according to the process conditions of the system. ...

Valve application requirements (1) General gate valves, ball valves, and globe valves are prohibited from regulating according to their structural characteristics. However, in process design, it is commonly used for mediation. Due to the conditioning application, the valve seal has been in a saving state for a long time, and the impurities in the oil have washed the seal, damaging the seal.

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 ...

The filter is an indispensable product in the fluid pipeline, which is generally installed at the inlet end of the pressure relief valve, pressure reducing valve and water level valve set equipment, which has the effect of eliminating impurities in the medium and avoiding the phenomenon of other equipment being stuck. After the medium passes through the filter cartridge equipped with a certain standard screen, the impurities are blocked.

Now the valve market is mixed, and illegal traders pretend to be innovative valves to be shoddy in order to make huge profits, which brings great safety hazards to the device project. Therefore, it is necessary to introduce to us the inspection of innovative valves. Now the valve market dealers mainly exist in the valve counterfeiting ...

Valve is a kind of commonly used hardware products, the valve in the assembly and installation process also has a certain skill requirements, otherwise the assembled valve may not show its own excellent performance, what are the skill requirements of the valve in the assembly process? ...

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 ...

1. The safety valve should have the equipment to prevent the hammer from moving by itself and the guide frame to restrain the lever from deviating, and the tension spring safety valve should have the equipment to improve the handle and prevent the adjustment screws from being twisted at will. 2. It should be installed straight in the pot merchant, the container ...

1. Impurities are stuck on the sealing surface of the valve The valve is sometimes closed suddenly, it may be that there are impurities stuck between the sealing surface of the valve, at this time should not be forced to close, the valve should be opened slightly larger, and then try to close, try repeatedly, it can generally be eliminated, otherwise it should be checked again...

For valves in operation, all kinds of valves should be complete and defective. For example, the bolts on the flange and bracket should not be short, and the threads should be free of defects, and no loosening is allowed. The fastening nut on the handwheel, if found to be loose, should be ...

(1) The sealing pair is spherical, disc eccentricity rotation planning The valve sealing pair is spherical planning, and the sealing effect is good. Together with the disc rotation center is planned to have a bias with the center of the valve seat, so the valve disc and the valve seat form a bias cam wedge sealing effect when closed, the valve ...

The flow rate and velocity of the valve mainly depend on the diameter of the valve, and are also related to the resistance of the structure of the valve to the medium, and at the same time have an intrinsic relationship with the pressure, temperature and concentration of the medium of the valve. Two...

(1) The dispatching valve belongs to the on-site dashboard, and the standard working temperature should be in the field 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. ...

G2010 ball valve for long-distance pipeline is designed for the transportation of long-distance pipeline media, which is a typical long-distance pipeline ball valve, which is suitable for various oil, natural gas, city gas pipelines, and can also be used in the equipment of general chemical products. The valve is completely in line with the United States Petroleum Institute API in terms of performance...

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 ...

A safety valve is an automatic valve that uses the medium's own force to expel an additional amount of fluid without any external force to avoid the pressure exceeding the additional safety value. When the pressure has recovered to normal, the valve closes again and prevents the continuous flow of the medium. (TSG ZF001-2006)

The conditioning valve, also known as the control valve, is a device that uses power operation to change the process parameters such as the flow, pressure, temperature, and liquid level of the conditioning pipeline medium in the field of industrial automation process control. It is mainly composed of the operating fulfillment mechanism and the regulating valve body, which receives relevant signals and changes the opening of the valve.

1. According to the processing requirements, some parts need to be polished, and there can be no processing burrs on the appearance; 2. All parts are degreased; 3. After the degreasing is completed, pickling and passivation will be carried out, and the cleaning agent does not contain phosphorus; 4. Rinse with pure water after pickling and passivation.
