Abstract
The invention relates to a control system for hydraulically driven self-acting (medium-driven) high-pressed inlet/outlet three-way valve bank, in particular to a control system suitable for switching over (thermal power) high-temperature, high-class, high-power and big-caliber high-pressure main circuits and bypasses. The invention aims to solve the problems that the control difficulty of switching over the (thermal power) high-temperature, high-class, high-power and big-caliber high-pressure main circuits and bypasses is higher, and moreover, an outside high-power or large-sized driving mechanism needs to perform operations, and meanwhile, the relevant requirement that the time of switching over the main circuits and bypasses is not more than 5s cannot be met. The problem that the control difficulty of switching over the main circuits and bypasses is high under the higher-difficulty conditions of big caliber, high power, high temperature and high class is solved, i.e. the control difficulty is reduced, the control system is simplified, and meanwhile, the energy consumption is saved.
Description
Technical field
The present invention relates to one self-powering type (media drive) height that surges and add entrance, outlet three-way valve valve set control system, specifically relate to high-temperatures such as being applicable to thermoelectricity, high pound level, high-power, the high control system that adds main road, bypass changeover of heavy caliber.
Background technique
Along with the sustainable growth of scientific and technical development and growth, various countries' economic strength, thermal power generation is towards more high-power, more extensive future development.Particularly the universal and application of super (super-) critical fired power generating unit technology, impels China's thermoelectricity technology must rise to the level of more increasing.Become the key factor of restriction China fired power generating unit development for the research and development of super (super-) critical fired power generating unit critical valves.For traditional to the high-temperatures such as thermoelectricity, high pound level, high-power, heavy caliber is high while adding main road, bypass changeover, it is larger that it controls difficulty, cannot meet again the requirement of main road, bypass changeover≤5s.Therefore, no matter be the needs from market economic development, or requirement China's strategic development direction, all need the development project of our the positive critical valves of putting into heavy caliber, high pound level.
Summary of the invention
The present invention is the defect existing in order to make up above-mentioned technology, the one self-operated three-way valve valve set control system that surges is provided, surge self-powering type (media drive) entrance, the self-powering type that surges (media drive) outlet three-way valve valve group being equipped with of employing is controlled needle-valve and pneumatic quick opening valve and is realized height is added to the control of main road, bypass changeover, and can play controllable adjustment in actuation time≤5s.
In order to achieve the above object, technological scheme of the present invention is: the self-operated three-way valve valve set control system that surges, comprises that main road, bypass, height add heat exchanger, inlet valve, initial valve, control needle-valve, control room, quick opening valve, outlet valve, tank gage, drain valve, handwheel, valve body, flap; Main road one end is entrance, and liquid is entered by entrance, being provided with initial valve near on the main road pipeline of entrance, is provided with height and adds heat exchanger on main road, adds heat exchanger upper end position at height, is provided with bypass, and bypass adds heat exchanger through height, between inlet valve and outlet valve; On the main road near entrance one end, be provided with inlet valve, be provided with and control needle-valve 6-a on entrance valve body, control needle-valve 6-a and be connected with inlet valve by pipeline one end, the other end is connected with the control needle-valve 6-b that controls outlet valve through inlet valve; Between control needle-valve 6-a and control needle-valve 6-b, be provided with quick opening valve, quick opening valve connects control room by guide line, connects tank gage on the branch road of connection control room simultaneously, and the tank gage the other end is through main road connection drain valve, and tank gage is fixed on height and adds on heat exchanger.
Described inlet valve and outlet valve comprise handwheel, valve body, flap.
When system is during in normal state, medium enters main road from entrance, and initial valve is in closing, after main road medium is full of, loine pressure raises, medium enters into height and adds heat exchanger, and after heat exchange, MEDIA FLOW is crossed main road, then enters bypass, when bypass one end flows to inlet valve, inlet valve flap is upper, and main road is open, and bypass is closed.Medium by outlet valve to downstream pipeline.
When height adds while breaking down, MEDIA FLOW is through high pressure heat exchanger, and it is too high that tank gage detects liquid level, and output warning signal inputs to control room, and control signal is sent in control room, opens the mediator depletion of quick opening valve by entering, in outlet valve internal hydraulic pressure cylinder cavity of resorption.Medium adds to oil hydraulic cylinder epicoele by runner hole, the upper and lower pressure difference of flap promotes flap and moves downward, until that inlet valve and outlet valve flap move to valve is the next, main road is closed, main road and pipe-line system are isolated, and delivery valve is opened the water in main road is discharged to pressure release simultaneously.
Beneficial effect of the present invention is: solved that the high-temperatures such as thermoelectricity, high pound level, high-power, heavy caliber highly add main road, bypass-switching contr difficulty is larger, and the needs external world is high-power or large-scale driving mechanism operates, and cannot meet again the requirement that main road, bypass changeover≤5s etc. are relevant simultaneously.Realized in the larger situation of the difficulty such as heavy caliber, high-power, high-temperature, high pound level to main road, breakthrough that bypass-switching contr difficulty is large.Reduce the difficulty of controlling, simplified again control system, saved again energy consumption simultaneously.
