China Refrigation Equipment Exhibition

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.

Advantages and Disadvantages of Butterfly Valve

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.

In 2022, do not forget the original intention, forge ahead, and continue to innovate

Entering 2022, our orders for butterfly valves and check valves are increasingly full, and the delivery date has been scheduled to April. We will continue to maintain a booming production and sales situation, and will not be affected by the Spring Festival holiday at all. The delivery date will start in late February.In addition, in a new field, the photovoltaic new energy business sector, our company continued to win the bid for the supporting projects for the newly expanded production base of JA Technology and LONGi Group.

Check Valve Applications

The purpose of using check valve is to avoid the backflow of medium, generally in the outlet of the pump should be installed check valve. In addition, the outlet of the compressor should also be installed check valve. In summary, in order to avoid the backflow of the medium, in the equipment, installation or pipeline should be installed check valve in general in the nominal diameter of 50mm of the horizontal pipeline are selected vertical lift check valve. Straight lift check valve in the horizontal pipeline and straight pipeline can be installed.

Pressure test method of check valve

Check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.

The principle of check valve opening and closing

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.

Features of electric ball valve

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.

Advantage of JIS Y-Strainer Ductile Iron Body

Y-kind strainer as an fundamental high-efficiency filtration system within the purification system engineering, has performed a exquisite position within the remedy of domestic wastewater and business sewage. with various blessings in layout and alertness, it's miles now desired.

Difference Between Butterfly Valve and Gate Valve

Different principlesButterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. It can also be used for on-off control of low-pressure pipeline media, and it mainly plays the role of cutting off and throttling. When the butterfly valve is fully opened to fully closed, it is usually less than 90. The butterfly valve and the butterfly rod have no self-locking ability. In order to position the butterfly plate, a worm gear reducer should be installed on the valve stem.

What Is The Advantage for Butterfly Valve

Butterfly Valve is a simple structure control valve,it can be used for switching control of low pressure pipeline medium. Our Butterfly Valve is a kind of valve that the disc rotate around the valve shafts to open and close. Features:1, opening and closing convenient and rapid, labor saving, fluid resistance is small, can often operate.2, simple structure, small size, short structure length, small volume, light weight, suitable for large diameter valve.3, can transport mud, the least liquid in the pipe mouth.4.
