Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structure distribution schematic diagram of the present utility model, wherein the arrow cooling water flow of representing water-cooling system to.
Embodiment
With reference to Fig. 1, a kind of high voltage direct current transmission valve group water-cooling system automatic constant-pressure system, it comprises at least one expansion drum 1, the bottom of described expansion drum 1 is provided with water inlet and delivery port, top is provided with controllable outlet valve 11, described expansion drum 1 inside is communicated with nitrogen cylinder 2 by pipeline, and described pipeline is provided with the electro connecting pressure gauge 3 of monitoring intraductal atmospheric pressure, and the pipeline between described electro connecting pressure gauge 3 and the expansion drum 1 is provided with tonifying Qi electromagnetically operated valve 4.Described tonifying Qi electromagnetically operated valve 4 can be manually and automatically switching in the control, so that deal with emergency episode.In addition, each parts of the present utility model are parts of stainless steel, possess than strong anti-oxidation, resistance to corrosion.
Be further used as preferred embodiment, described expansion drum 1 quantity is two, is divided into left expansion drum 12 and right expansion drum 13, and with pipeline connection top separately, the water inlet of described right expansion drum 13 is communicated with pipeline with the delivery port of left expansion drum 12 mutually for the two.Expansion drum 1 by two connections are set makes air pressure easy to control, and a water capacity also obtains increasing.
Be further used as preferred embodiment, described controllable outlet valve 11 is an exhaust solenoid valve.Described exhaust solenoid valve is opened and closed by PLC control.
Be further used as preferred embodiment, described controllable outlet valve 11 is positioned at the top of left expansion drum 12, and the top of described right expansion drum 13 is provided with monitoring pressure by air pressure transmitter 131, and the upper-lower position of inner chamber all is connected with the fluid level transmitter 132 of monitoring liquid level.Because left expansion drum 12 is communicated with right expansion drum 13, so the air pressure and the liquid level data of two expansion drums 1 being detected of pressure transmitter 131 and fluid level transmitter 132 are equivalent.
Be further used as preferred embodiment, described nitrogen cylinder 2 has two groups, and every group is made of two nitrogen cylinders 2.In two groups of nitrogen cylinders 2, one group is commonly used, and one group is reserve.
