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.

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.

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.

Check valve is a valve installed in the pipeline to prevent the backflow of media. Check valves can be used on many types of pipelines such as over water, oil and gas, etc.

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.

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.

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.

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 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 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.
