Tips for using Fujian Beacon Valve Groove Butterfly Valve:

1.The grooved butterfly valve with the above characteristics accelerates the action of the valve disc when it is close to full closure, and water hammer (water impact pressure) is prone to occur, and when it is close to full closure, the slower the valve action is better, so a throttling mechanism can be set on the valve disc.

2.The groove butterfly valve is to use the medium pressure of the pipeline itself as the power source to open and close, adjust, and combine the front pilot valve and the small pipeline of the system differently, which can have nearly 30 kinds of functions, and is now gradually more commonly used.

3.The pilot valve depends on the change of water level and pressure as the control object, because there are many types of pilot valves, can be used alone or several combinations, the main valve can obtain the function of individual or compound adjustment of water level and water pressure and flow. However, the main valve is similar to the globe valve, when the valve is fully open, its pressure loss is much larger than that of other valves, and the closer the opening loss coefficient is to the full closure, the more sharply it increases, and the larger the valve diameter, the more significant.

4.In addition, the throttling and action part of the pilot valve should be avoided as much as possible to avoid setting up extra-small diameter orifice, so as not to block. If necessary, add a filter screen, regularly overhaul and set up a bypass pipeline. The development and use prospects of this valve are promising.

【The use of grooved butterfly valve】The overall design and structure of grooved butterfly valve is unique and novel, and it is widely popular in the valve industry. When the valve is running, it will rotate with the cam and release the contact pressure on the signal device according to the predetermined position, and also send out the corresponding "on" and "off" electrical signals to show the opening and closing state of the butterfly valve. It has the advantages of quick installation, simple and reliable, light weight, flexible operation and convenient maintenance.

Good sealing, but also with the desired speed of connection with pipe fittings. It can be widely used in water supply and drainage, fire protection, petroleum, chemical, pharmaceutical, steel and other pipelines as truncation or adjustment.

1. Shut-off valves: mainly used to cut off or connect the medium flow in the pipeline. Such as globe valves, gate valves, plug valves, ball valves, operation valves, etc.;

2. Control valves: mainly used to adjust the pressure and flow of the medium in the pipeline. Such as regulating valves, throttle valves, pressure reducing valves, etc.

3. Check valves: mainly used to prevent the backflow of medium. Such as various different types of check valves;

4. Diverter valves: used to change the direction of the flow of the medium in the pipeline, and play the role of distributing, separating or mixing the medium. Such as distribution valves, three-way or four-way ball valves, traps, etc. of various structures;

5. Safety valves: used for system overpressure safety protection, discharging excess media, and preventing pressure from exceeding the specified value. Such as various types of M safety valves;

7. Other special angle valves, such as sewage river, venting wide, pigging valve, etc.

The grooved butterfly valve has a coordinated proportion, strong practicability, easy installation, convenient operation, firm and reliable, and its main function is to control the flow of medium in the pipeline. The valve body is made of ductile iron and has good high temperature resistance. The two ends of the grooved butterfly valve are connected to the fluid pipeline by means of clamp connection, which can greatly reduce the cost of structure production compared with the previous connection method.

The grooved butterfly valve is made of carbon steel as the main material, and the valve body is welded with thick-walled seamless pipe, which is very reliable in quality, beautiful in appearance, and very durable. It can be used in a variety of media, such as: corrosive, non-corrosive gas, semi-fluid, liquid, solid powder and other pipeline containers to adjust and throttle equipment.

The butterfly valve is suitable for food, chemical, pharmaceutical, shipbuilding, water supply and drainage, petroleum, energy and other systems, and the groove butterfly valve is also widely used in fire protection systems, high-rise buildings and pipeline systems that need to show the opening and closing status of the valve.

Do you need electric drive parameters or grooved butterfly valve parameters? What is the standard?

Due to the characteristics of simple structure, fast and lightweight, scientific and reliable, safe and economical and small space occupation, the grooved butterfly valve is widely used in drainage, fire protection, petroleum, chemical, pharmaceutical, steel and other pipelines, and its main role is to cut off or regulate. When using grooved butterfly valves, it should be noted that the butterfly valve can be installed on the pipeline at any position in the space, and the installation position should ensure the convenience of use, maintenance and replacement. Grooved butterfly valve installation allows for bi-directional flow.

The grooved butterfly valve should be stored in a dry place indoors before installation to maintain the normal operation of the instrument.

Turbine groove butterfly valves are not only widely used in general industries such as petroleum, gas, chemical industry, water treatment, etc., but also used in the cooling water system of thermal power stations. The structural principle of the turbine groove butterfly valve is particularly suitable for the production of large-diameter valves. There are two commonly used butterfly valves: clamp butterfly valve and flanged butterfly valve.

The clamp butterfly valve is to connect the valve between the two pipeline flanges with stud bolts, and the flanged butterfly valve is to have a flange on the valve, and the flanges at both ends of the valve are connected to the pipeline flange with bolts. Turbine groove butterfly valves are not only widely used in general industries such as petroleum, gas, chemical industry, water treatment, etc., but also used in the cooling water system of thermal power stations.

Turbine groove butterfly valves can be widely used in water supply and drainage, fire protection, petroleum, chemical, pharmaceutical, steel and other pipelines as truncation or adjustment. The grooved butterfly valve is designed with foreign advanced technology and the company has improved it many times. The turbine groove butterfly valve has the advantages of fast, simple, safe, reliable, not limited by the installation site, convenient for the maintenance of pipelines and valves, vibration and sound insulation, and within a certain angle range, it can overcome the imitation difference caused by the different shafts of the pipeline connection, and solve the thermal expansion and contraction caused by the temperature difference.

The sealing performance of the turbine groove butterfly valve is reliable, not limited by medium injection (two-way seal), the flow area is large, the flow resistance coefficient is small, and the flow capacity is large. The turbine groove butterfly valve has the advantages of fast, simple, safe, reliable, not limited by the installation site, convenient for the maintenance of pipelines and valves, vibration and sound insulation, and within a certain angle range, there is an imitation difference caused by overcoming different shafts of pipeline connection, and solving the thermal expansion and cold contraction caused by the temperature difference; If a turbine grooved butterfly valve is required to be used as flow control, the main thing is to select the correct size and type of valve.

Choosing a suitable grooved butterfly valve is very important in order to ensure the work of the equipment, piping. How to choose a suitable grooved butterfly valve? First of all, the general category of valves should be determined according to the functional requirements of engineering equipment (such as retreat check valves or safety valves, etc.), and then the basic parameters of the selected valves (nominal pressure, DN comply with the applicable requirements of pipelines and pressure media, flow, and other types).

In addition, according to the installation location and surrounding environment, the appropriate connection form, connection size and driving mode of the valve and pipeline should be selected. Of course, the sealing performance of the valve, the opening and closing speed, the action sensitivity performance and the service life of the valve, the cost should also be considered as needed.

In order to protect the safety of the equipment and avoid overpressure and **, we can use the safety valve. If the medium conveyed in a project pipeline is not allowed to have backflow, we can consider using a check valve. But there are also many types of check valves, there are lifting check valves, swing check valves, butterfly valves, foot valves, their structure, performance are different, should be selected on request.

If the suction line of the pump is fitted with a check valve, so that the pump who cannot or does not self-priming the pump exhausts its empty water pump, an optional foot valve, and install it at the end of the suction pipe of the pump. Then, according to the three basic parameters, of which nominal pressure is the most important one, the appropriate valve is selected.

It should be noted that the nominal pressure refers to the maximum allowable operating pressure of the valve at the reference temperature. When the actual operating temperature exceeds the reference temperature, the maximum allowable working pressure of the valve is reduced, so you must pay attention when choosing. Valve, such as copper alloy, if the relative nominal reference temperature of 4 kgf square centimeter, when the temperature rises to 200, its actual maximum working pressure drops to kgf cm, and when the temperature rises to 25 090, the actual maximum working pressure of kg further decreases the force cm2.

This is also the case with other valves such as gray cast iron, malleable cast iron, ductile iron valves, and steel valves.

According to the use of medium, pressure, flow, working conditions and other conditions.
