What are the advantages of a butterfly valve?
It is mainly composed of valve body, valve stem, butterfly plate, and sealing ring. The valve body is cylindrical, with a short axial length and built-in butterfly plate.
Butterfly valve features.
1、Butterfly valve has a simple structure, small volume, lightweight, material consumption saving, small installation size, rapid switching, 90° reciprocal rotation, small driving torque, etc. It is used to cut off, connect and regulate the medium in the pipeline, with good fluid control characteristics and closing sealing performance.
2、Butterfly valve can transport slurry and accumulate the least liquid at the mouth of the pipeline. Good sealing can be achieved under low pressure. Good regulating performance.
3、The streamlined design of the butterfly plate makes the fluid resistance loss small, which can be an energy-saving product.
4、The stem is a through-stem structure, tempered, with good comprehensive mechanical properties and anti-corrosion and anti-scuffing. When the butterfly valve opens and closes, the stem only rotates and does not lift and run, the packing of the stem is not easy to destroy and the seal is reliable. Fixed with the butterfly plate taper pin, the outer extension is designed to prevent the stem from crashing out when the stem is accidentally broken at the connection with the butterfly plate.
5、 The connection methods are flange connection, butt-clamp connection, butt-weld connection, and lug-to-clamp connection.
6、Driving forms include manual, worm wheel drive, electric, pneumatic, hydraulic, electro-hydraulic linkage, and other actuators, which can realize remote control and automatic operation.
Advantages of butterfly valve:
1、It is convenient to open and close quickly, saves energy, has small fluid resistance, and can be operated frequently.
2、Simple structure, small size, short structure length, small volume, lightweight, suitable for large diameter valves.
3、It can transport slurry and accumulate the least liquid at the mouth of the pipe.
4、Good sealing can be achieved under low pressure.
5、Good adjustment performance.
6、The effective flow area of the valve seat channel is larger when fully open, and the fluid resistance is smaller.
7、The opening and closing torque is small, because the butterfly plate on both sides of the rotating shaft is basically equal to the action of the medium, and the direction of the generated torque is opposite, so it is less effort to open and close.
8、Sealing surface material generally uses rubber and plastic, so the low pressure sealing performance is good.
9、Easy to install.
10, flexible operation, the manual, electric, pneumatic, and hydraulic modes can be selected.
Disadvantages of butterfly valve:
1、Small operating pressure and temperature range.
2、The sealing is poor.
Butterfly valve can be divided into offset plate type, vertical plate type, inclined plate type, and lever type according to the structure form.
According to the sealing form, there are two types soft sealing type and hard sealing type. The soft seal type generally adopts a rubber ring seal and the hard seal type usually adopts a metal ring seal.
According to the connection type, it can be divided into flange connection and buttress connection; according to the transmission mode, it can be divided into manual, gear transmission, pneumatic, hydraulic, and electric.
Butterfly valve installation and maintenance.
1、At the time of installation, the valve flap should be stopped in the closed position.
2、The opening position should be determined by the rotation angle of the butterfly plate.
3、Butterfly valve with a bypass valve should open the bypass valve before opening.
4、It should be installed according to the installation instructions of the manufacturer, and the butterfly valve with a large weight should be set up with a firm foundation.
5、Installation position, height, import, and export direction must meet the design requirements, and the connection should be firm and tight.
6、All kinds of manual valves are installed on the insulation pipeline, the handle shall not be down.
