Ball valve ball is floating in the medium pressure, the ball can produce a certain displacement and pressure in the export side of the sealing surface, to ensure that the export side seal.
Floating ball valve structure is simple, good sealing, but the ba

Ball valve can be divided into: floating ball valve, fixed ball ball valve, track ball, V type ball valve, three-way ball valve, stainless steel ball valve, forged steel ball valve, unloading ash valve, anti sulfur ball valve, three-way ball valve, gas dy

Ball valve installation
1. Remove the protective cover on both sides of the flange, the valve is fully open in the state to wash clean.
2. iInstalled before the required signal (electricity or gas) to carry out the whole test (to prevent the impact of t

General pumping station project, the pump outlet check valve selection, should follow the following principles: the pump outlet pipe diameter smaller pipe, that is, DN<50mm, should be used to lift check valve.

1. swing check valve is generally installed in the horizontal pipe: for the caliber DN~80mm check valve, can also be installed in the vertical or upward inclined pipe.
2. Straight lift check valve should be installed in the horizontal pipe; vertical lift

1. Remove the protective cover on both sides of the flange, the valve is fully open in the state to wash clean.
2. Before installation should be required by the signal (electric or pneumatic) to carry out the whole test (to prevent the impact of transpor

1. To remove the protective cover on both sides of the flange end, the valve is fully open in the state to wash and clean.
2. Before installation shall be in accordance with the provisions of the signal (electric or gas) for testing machine (to prevent

According to media wear bushing series wear a 0.6MPa1.2MPa general 0.4MPa0.8MPa serious 0.2MPa0.4MPa2. of single screw pump speed choice: single screw pump because of its structural features, most in the delivery of high viscosity liquids and particles co

Control valve, also known as the control valve, it is a process control system with power to change the flow of the device. Regulating valve by the actuator and valve (regulator).

The multistage submersible pump will delivery to Bangladesh today. We have ready everything. The pump can be used in river. And the motor will been cooler all the time.

YW liquid sewage pump in the liquid, the pressurized environment, underground fluid flow to the ground, for people to use, but liquid pump in use process, vibration caused by noise to cause harm to the staff, also will affect the liquid pump work efficien

Trouble of electric pump include this as follow:
1. Electric pumping liquid pump electric motor does not run after the electric pump
2.Electric pumping liquid pump electric pump after the occurrence of abnormal sound and do not rotate or turn very slow

Submersible pump installation, the first should check whether the rotation of the pump shaft is flexible, if it is found that the pump shaft rotation is not flexible, there is impact sound, pump shaft radial shaking, should be excluded after the installat

Safety valve some used in the water tank, the safety valve of water or other liquid at room temperature should check with the water pressure, so that it can be more realistic conditions, because water is incompressible, so sensitive in reaction to pressur

In order to stabilize the pressure, usually in front of the system, the gas storage pressure vessel is connected in parallel. Some calibration units have been equipped with electric or pneumatic compressor, its own source of pressure. Some equipped with m
