Together into a high pressure valve repair or maintenance of that high added-way valve manufacturers - Jiangyin Oulei Si, professional power valve maintenance, high added together into a valve, the heater water-way valve (the valve together into ), said hydraulic high-added port-way valve (water inlet bypass) is used in high-pressure shell side of heater when the water level rose rapidly within the high pressure quick disconnect water supply to ensure a high water plus housing dissatisfaction, do not over-pressure; Water does not enter the turbine through the extraction pipe. Use of high pressure feedwater heater inlet valve (inlet valve), outlet valve (outlet check valve) products were used to 50MW-600MW boiler heater inlet and outlet pressure, as high pressure protection valve. High pressure during operation, when a leak or trap piping, etc. will result in failure of steam side of the water level rise, could easily lead to water intrusion into the high-pressure steam turbine. To prevent accidents, when the steam side of the water level reaches the alarm level, the electric contact device contacts the sender connected to the water level, fast opening and closing the solenoid valve open, the condensate into the inlet valve above the piston, inlet valve valve, high pressure water supply cut off imports , while the bypass open, water supply through the bypass into the boiler, high pressure splitting, thus ensuring the normal operation of the unit. High increase investment, the inlet valve valve water pressure in the system to automatically turn on and off bypass, high pressure water through the heater into the boiler, thereby increasing the thermal efficiency of power plants and ensure safe operation of unit.
Together into a high pressure valve repair or maintenance of that high added-way valve is a high pressure inlet valve or outlet valve of the following maintenance work carried out under conditions: (1) put into operation in high pressure occurred during the establishment of high internal pressure increases up, the valve can not move, resulting in high increase can not be put into operation in time, affect the unit's high investment rate increases.
(2) seat, the valve as long-term erosion caused by the leakage, which in the normal operation of the low-temperature water circuit through the valve seat and valve sealing parts export flow to high pressure, mixed with heated water, so that the final a significant reduction in water temperature, seriously affect the plant thermal efficiency.
Together into a high pressure valve repair or maintenance of that high added-way valve brand, according to the company many years of maintenance experience are: France Alstom together into a high pressure valve repair, Japan, Okano high added-way valve repair, Velan high added-way valve repair, valve repair Will high plus links, Adelaide Wood high plus-way valve repair, Dilan Si together into a high pressure valve repair, Tektronix high pressure into the valve together maintenance, high added together into a valve repair or maintenance of that high added-way valve. Here are some photos Jiangyin Oulei Si, in the power plant into a high pressure valve repair together.
