Electric butterfly valve means that the butterfly valve is equipped with an electric actuator, which controls the opening and closing of the valve through the electric energy provided by the power supply, so as to realize remote centralized control and automatic operation. Electric butterfly valve can be divided into flange type and disc type according to the connection method, which is an important execution unit in the field of industrial automation control.
Advantages:1. easy and quick to start and close, labor-saving, low fluid resistance, can be operated frequently2. Simple structure, small size, short structure length, small volume, light weight3. start and close torque is small, because the butterfly plate on both sides of the shaft is basically equal to the action of the medium, and the direction of the torque generated is opposite, so it is relatively labor-saving4. The material of sealing surface generally adopts rubber, plastic, so the low pressure sealing performance is good.5.
FIRST:The difference between butterfly valve has a pin and without pin: Price: the without pin butterfly valve is more expensive than the pin ones. Usage: WITHOUT PIN TYPE REDUCE THE RISK OF LEAKAGE.
Butterfly valve is a type of valve that uses a spherical butterfly plate as the opening and last component and turns with the valve stem to open, close and alter the fluid channel. the butterfly plate of the butterfly valve is set up in the diameter route of the pipe. in the cylindrical channel of the butterfly valve frame, the disc formed butterfly plate rotates around the axis of the valve stem at an perspective among 0 ° and 0 °. whilst the butterfly plate is at 0 °, the valve is closed, and when the butterfly plate is at ninety °, the valve is absolutely opened.
Test valve refers to the hole and remaining elements of the circular disc and with the aid of its own weight and media stress generated motion to block the media float lower back valve. automatic valve elegance, additionally referred to as test valve, one-way valve, backflow valve or isolation valve. disc movement is split into lifting and swing. elevate test valves are comparable in creation to globe valves besides for the stem that drives the disc. the medium flows in from the inlet quit (decrease side) and flows out from the hole give up (higher aspect). valve
The check valve opening and closing parts are opened or closed by themselves by the flow and force of the medium to prevent the backflow of the medium. The valve is called a check valve. The check valve belongs to the automatic valve category, which is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents. The check valve, also known as a one-way valve or a check valve, is used to prevent the backflow of the medium in the pipeline.
1. Butterfly valve is composed of valve body, valve seat, valve plate and valve stem, and all fittings are exposed and can be seen at a glance; Ball valve is composed of valve body, valve core (a round ball) and valve stem. The position of valve core is inside the valve body, and only part of it can be seen by naked eyes, so the sealing performance of ball valve is better than that of butterfly valve.2. Butterfly valves are relatively simple in structure, and butterfly valves with low pressure are generally used. The zui high pressure of butterfly valves can only reach 64kg.
Gate valve is a kind of cut-off valve, which is used to connect or cut off the medium in the pipeline. Gate valve's opening and closing member gate, driven by the valve stem, extend the seat to do linear lifting movement.Advantages of the gate valve.1. low fluid resistanceBecause the valve body of the gate valve internal media channel is straight, the media flow through the gate valve does not change its flow direction, so the fluid resistance is small.2.
1. Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, quick switch, 90 reciprocating rotation and small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline, and has good fluid control characteristics and closing and sealing performance.2. Butterfly valves can transport mud, and the liquid accumulated at the pipe mouth is the least. Under low pressure, good sealing can be achieved. Good adjustment performance.3.
Hard seal butterfly valve is called "hard seal" when both sides of the seal are made of metal or other hard materials. The sealing function of this kind of seal is poor, but it is resistant to high temperature, wear and tear, and has good mechanical function.
