Fine Smart Electric Actuator
Introduction
The grooved fire butterfly valve is a series of new connection valves designed and manufactured by introducing similar advanced products from the United States and Germany. It is fast, easy, safe and reliable to install, and is not restricted by the installation site. It is convenient for the maintenance of pipelines and valves, and has isolation Vibration sound insulation and a certain angle range have the advantages of overcoming the pseudo-difference caused by the non-axial connection of pipelines and solving the thermal expansion and contraction caused by temperature differences. It is widely used in water supply and drainage of fluid conveying pipelines, and as a control fluid in pipeline projects such as fire protection, air conditioning, gas, petroleum, chemical industry, water treatment, municipal administration, and shipbuilding. The groove butterfly valve adopts worm gear and worm drive, and then the cam rotates to press or release the contact on the signaling device according to the predetermined position, and the corresponding "on" and "off" electrical signals are output to display the opening and closing status of the butterfly valve. There are two types of groove butterfly valves: handle groove butterfly valve and turbine groove butterfly valve.
Precautions For Use
1. The butterfly valve can be installed on the pipeline at any position in the space.
2. The installation position of this butterfly valve should ensure the convenience of use, maintenance and replacement.
3. When installing the grooved butterfly valve, the direction of flow of the pipeline medium can be ignored, that is, bidirectional flow is allowed.
4. The butterfly valve should be stored in a dry place indoors before installation, with the valve plate slightly open 4°~5°.

Features Of Grooved Butterfly Valve
1. Small and lightweight, easy to disassemble and repair, and can be installed in any position.
2. The structure is simple and compact, and it can open and close quickly with 90% rotation.
3. Small operating torque, labor-saving and lightweight
4. The flow characteristics tend to be linear and the adjustment performance is good
5. Tens of thousands of opening and closing tests, long service life
6. Sealing is achieved and gas test leakage is zero.
Nine Advantages Of Grooved Butterfly Valve
1. Quickly adopt grooved clamp connection and corresponding pipe fittings to install the pipeline. There is no need for welding, secondary galvanizing or secondary installation during construction. Increased placement speed.
2. Lightweight: The clamp connection is light in weight, has a small number of bolts, is easy to install, and does not require special skills.
3. Reliability: Scientific and reasonable structural design, unique C-shaped rubber sealing ring, and triple close injection ensure the reliability of the continuous sealing.
4. It is safe to use grooved clamps to connect and install corresponding pipe fittings. Only mechanical assembly is required, no welding is required, and there is no open flame. Therefore, there is no welding slag to cloud the pipeline, which ensures the safety of the construction site and is suitable for construction under fire ban conditions. , especially suitable.
5. Economical: Because installation is fast, no special skills are required, and the installation repair rate is low, the overall installation cost can be reduced by 30-50% compared with flanges.
6. Small space occupied: The grooved clamp connection takes up about 70% of the space of the flange, and because the number of fastening bolts is small and non-specific, it is particularly suitable for construction in narrow environments.
7. Simple maintenance. Safe and reliable product quality. As long as it is installed properly, the pipeline will pass the pressure test once and operate safely. There is no need for maintenance at ordinary times, and spare parts do not need to be replaced for decades.
8. Wide range of practical pipes: The grooved clamp connection can be used to connect various seamless steel pipes, galvanized steel pipes, coal-joined steel pipes, stainless steel pipes, copper pipes and other metal pipes.
9. Flexible connection of pipelines can be achieved. The pipelines connected by flexible groove-type clamps are flexible systems, which can absorb the length displacement of the pipes due to temperature changes and allow the pipes to have a certain deflection angle.
