Wuzhong instrument G1610 slag lock valve introduction

The process of shell experiments and seal experiments done by turbine fixed ball valves in some artificial environments is as follows. 1. The double blocking and discharge function of the turbine fixed ball valve: the turbine ball valve is fixed by using the tension spring preload floating valve seat, when the valve is in two different states of full open and fully closed, the flow ...

First, there is a leak in the safety valve. The industry said that when there is a small leakage in the safety valve, it is generally not easy to find, but even a small leakage point will expand in the erosion. The test method is to test ...

Insist on the cleanliness of valves and actuators as much as possible. The valve is drained after the flow test. During storage and installation, it is important to avoid the ingress of contaminants. Assuming that there is a problem, check it according to the instructions. Do not use a crowbar or an excessively large ...

Wuzhong is a leading enterprise in China's process industry automatic control valve industry, founded in 1959, a national third-line construction enterprise. The company has always adhered to the concept of professionalism, dedication, innovation and transcendence.

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 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 ...

Pneumatic cylinders and hydraulic cylinders are two common components in the mechanical field, both of which have the functions of transmitting energy and converting energy. Although the two seem to be similar, there are still great differences in the operating principle, application field, operation method, and application effect. ...

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. 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 ...

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. The valve positioner is divided into pneumatic valve positioner, electrical valve positioner and intelligent valve positioner according to the input signal. (1) The input signal of the pneumatic valve positioner is a standardized gas signal, for example, the 20-100kPa gas signal, and its output signal is also a standardized gas signal. （ ...

1. Pole change speed regulation This speed regulation method is to change the number of stator pole pairs of the cage motor to achieve the speed regulation intention by changing the wiring method of the stator winding, and the characteristics are as follows: it has hard mechanical characteristics and good stability; No slip loss, high power; The wiring is simple, the operation is convenient, and the price is ...

The commonly used medium for valve pressure test is water, oil, air, steam, nitrogen, etc., and the pressure test methods of various valves are as follows. (1) Globe valve and throttle valve The strength test of globe valve and throttle valve, usually the assembled valve is placed in the pressure test frame, the valve disc is turned over, and the medium is injected to...

1) General purpose valve (general purpose valve): a general term for a wide range of valves, also known as ordinary valves. It is not a valve for a specific condition and a specific purpose. Although there is no clear definition of a universal valve, it mainly refers to a pressure below 2MPa, ...

　　First, the effect of pipeline identification Why do you need to do pipeline identification? Intent: To facilitate the identification of substances in industrial pipelines, ensure safe production, and avoid misjudgment in operation and equipment maintenance. Carry out ...

Valves are the most common equipment in chemical enterprises and play a great role. They seem to be simple and easy, but in the actual operation process, they also need to meet the relevant technical requirements, otherwise they will cause safety accidents. Only the valves related to our liquid level appearance are introduced here, and other equipment is not analyzed. ...

There are two main reasons for the leakage of cryogenic valves, one is internal leakage; The second is leakage. 1) Internal leakage of the valve The main reason is the deformation of the sealing pair at low temperature. When the temperature of the medium drops to the point where the data undergoes a phase change, the volume changes ...

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.

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 ...

1. Before the device, check whether the valve has notched parts, whether the type is correct, whether there are debris in the valve body, and whether the muffler is blocked. 2. Close the valve and cylinder. 3. Device the cylinder on the valve, the direction of the equipment is parallel or straightened with the valve body, and check whether the screw holes are aligned.
