Description
Technical field
The utility model relates to DC converter valve technical fields, more particularly, to a kind of connection structure of DC converter valve.
Background technique
In DC converter valve operational process, heat can be largely distributed, the cold water- cooling generator of valve realizes the cold and hot exchange of converter valve,
The cold tower entrance of valve is passed in and out in the cold inner cold water of valve, configures valve tower differential pressure indicator, to monitor disengaging water pressure, when disengaging differential water pressures are abnormal
When then judge valve tower internal watercourses have leakage etc. failures.Two branch water are usually installed respectively on valve tower disengaging water main at present
Pipe is directly accessed differential pressure indicator ontology, to realize differential pressure indicator to Inlet and outlet water pressure monitoring and compare, generates pressure difference.Existing company
Mode is connect in DC converter valve operational process, branch water route replacement failure differential pressure indicator cannot be closed.Differential pressure indicator is verified every year
When, tester will be attached to simulate disengaging water pressure with differential pressure indicator, branch water pipe at this moment must be removed, by tester
Water pipe is connect with differential pressure indicator, and ± 800 kilovolts of four valve groups of DC converter station configure 24 pieces of differential pressure indicators altogether, dismounts branch water pipe workload
It is larger.
Utility model content
The purpose of this utility model is intended to overcome the shortcomings of the prior art, provides a kind of differential pressure indicator checked operation side
Just and the connection structure of high-efficient DC converter valve.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of connection structure of DC converter valve differential pressure indicator, including differential pressure indicator, the valve tower water inlet pipe being connect with differential pressure indicator and
