1. The safety valve should have the equipment to prevent the hammer from moving by itself and the guide frame to limit the lever from deviating, and the spring-type safety valve should have the equipment to raise 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. 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 ...

Valve is a kind of commonly used hardware products, the valve also has certain technical requirements before assembling and in the process of the device, otherwise the assembled valve may not reflect its own excellent function, what are the technical requirements of the valve in the assembly process? ...

1. System overview The valve automatic control system controls the solenoid valve equipment placed in the field by announcing the instructions of the control service center in a wireless way, and then realizes the opening and closing of the solenoid valve, and the opening and closing status of the valve, the operation status, whether the equipment is online, historical data inquiry, etc.

Valves are control components in fluid transportation systems, which have the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems, from the simplest shut-off valves to the most complex valves used in automated control systems, are available in a variety and size.

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 surface can be divided into magnetoelectric system appearance, electromagnetic system appearance, electric system appearance and ...

Digital Factory Outline The use of CAD and PDM systems, ERP and other related information systems have been appropriately popularized in many production factories at present, and Wu Zhong has completed the "digital factory" skills and systems after the key link of "how to make → process planning".

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 widely used for mediation. Due to the conditioning application, the valve seal is in a throttling state for a long time, and the impurities in the oil wash the seal, damaging the seal.

The basic structure of the centrifugal pump is composed of six parts, namely the impeller, the pump body, the pump shaft, the bearing, the sealing ring, and the stuffing box. 1. The impeller is the core part of the centrifugal pump, its speed is high and the output is large, and the blades on the impeller play a role in the ...

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...

Pneumatic ball valves are ball valves with pneumatic actuators. The detailed classification of pneumatic ball valves includes: stainless steel pneumatic ball valves, plastic pneumatic ball valves, sanitary pneumatic ball valves, carbon steel pneumatic ball valves, two-way pneumatic ball valves, three-way pneumatic ball valves, and four-way pneumatic ball valves. ...

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.

The selection of control valve is a very complex thing, in order to ensure the use of control valves, customers only need to provide process parameters and use requirements to valve manufacturers, because valve manufacturers have rich experience in valve use, so they can provide customers with the best cost-effective valve products. ...

Valve is a device used by Gongliang to control the direction, pressure and flow of fluid in the fluid system. A valve is a device that allows the flow or suspension of the medium (liquid, gas, powder) in the piping and equipment, and can control its flow. The valve is a controlling part in the pipeline fluid delivery system, ...

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; ...

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? ...

The hydraulic maintenance module uses the hydraulic locking method to control the inlet and outlet oil circuits and load oil circuits of the electro-hydraulic servo valve. The module has the following three functions: 1. Locking function When the system is in normal condition, the hydraulic lock is in the guide...

1. Introduction to gate valves Gate valve refers to the valve in which the opening and closing parts (rams) move in the straight direction of the medium (channel axis) to complete the opening and closing. Among the various types of valves, gate valves are the most widely used one. Gate valves are mainly used as shut-off medium in pipelines, i.e. ...

Features of Gate Valve: Light weight: The body is made of high-grade ductile iron, and the weight is about 20%-30% less than that of the traditional gate valve, and the device is easy to repair. Flat-bottomed gate seat: The traditional gate valve is often washed by water and the pipe is due to foreign objects such as stone, wood, cement, iron filings, etc.

Cryogenic valves are mainly used in ethylene, liquefied natural gas units, air separation equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tanks and tankers, pressure swing adsorption oxygen production devices, etc., the main varieties are cryogenic ball valves, cryogenic globe valves, etc. ...
