Advantages Of Two Shaft Wafer Type Butterfly Valve

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 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.

The Difference Between Ball Valve and Butterfly Valve

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.

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.

Different installation requirements for rubber soft joints

Rubber soft joints have been widely used in the industry. The installation of rubber soft joints requires different installation requirements according to different types of rubber joints. Threaded screwed rubber joints: Pay attention to the installation of screwed rubber joints. The pipe fittings are laid flat on a horizontal surface. When installing, it is necessary to screw the threaded structure into the lifting section of the pipe fittings, and then screw the other section of the pipe fittings, keeping it on the horizontal plane to prevent uneven force during the installation process.

Characteristics of Strainer Valve

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.

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.

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.

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.

The meaning of butterfly valve and the problems that are easily overlooked in the use process

In production and life, the emergence of valves is that the utilization rate of their valves and accessories is getting higher and higher, such as check valves, check valves, electric butterfly valves, pneumatic butterfly valves, rubber soft joints, electric ball valves, one-way valves, and wafer butterfly valves. , filter, etc., which have brought great convenience to production and life.
