Double Door Check Valve

Check valve is to rely on the flow of the medium itself and automatically open and close valve disc, used to prevent the media flow back valve, also known as check valve, one-way valve, countercurrent valve, and back pressure valve. Check valve is a kind of automatic valve, its main function is to prevent media backflow, prevent pump and drive motor reverse, as well as the discharge of container medium. Check valves can also be used to supply lines in which pressure may rise to exceed system pressure in the auxiliary system.

Matters Needing Attention in the Use of Gate Valves

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.

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.

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.

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.

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.

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.

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.
