The Chinese Refrigation Equipment Exhibition is the most special exhibition in Refrigation field.Our Diefei Brand Check valve and Butterfly valve is an important part of this Exhibition.We have the expertise and experience to produce,also have a big After-service team . We get the high apprecition from our customers.
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.
1. Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is forbidden. 2. The double gate valve should be installed vertically (i.e. the valve stem is in the vertical position and the handwheel is at the top). 3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force). 4. Gate valve with transmission mechanism shall be installed according to the product instruction manual. 5.
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.
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.
The filter net adopts stainless steel double-layer net structure, which is durable, advanced in structure, small in flow resistance, convenient in sewage discharge, etc. It can be used in water, steam, oil, nitric acid, urea, oxidizing medium and other media. According to the user's needs, the mesh number of filter screen should be set, generally, the water supply network is 18-30 mesh, the ventilation network is 40-100 mesh, and the oil supply network is 100-480 mesh.
The high-pressure pneumatic ball valve only needs to use the pneumatic actuator to rotate the air source by 90 degrees and a small rolling torque to be tightly closed. Completely equal valve body cavity provides medium with low resistance and straight-through flow path. It is generally believed that the ball valve is suitable for direct opening and closing applications, but recent developments have designed the ball valve so that it can be used for throttling and control systems.
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.
Advantage 1. The opening and closing is convenient, quick, labor-saving, low in fluid resistance, and can be operated frequently.2. Simple structure, small overall size, short structural length, small volume and light weight, which is suitable for large-diameter valves.3. Mud can be transported, and the liquid accumulated at the pipe mouth is the least.4. Under low pressure, good sealing can be achieved.5. Good adjustment performance. 6. When fully opened, the effective circulation area of the valve seat channel is large, and the fluid resistance is small.7.
