Abstract
The utility model provides vacuum breakdown device of vacuum in a kind of hydroelectric power plant's pipeline, the pipeline includes technical water supply main sewer and cooling water drainage water pipe, Upstream section of the water outlet of cooling water drainage water pipe with technical water supply main sewer connects, be connected with the water outlet of cooling water drainage water pipe place technical water supply main sewer downstream at be also provided with and communicated with snorkel, check valve is provided on snorkel, that is non-return valve, alternatively referred to as one-way gas-compensating valve, with realize through snorkel into technical water supply main sewer one-way ventilating.Channel interior vacuum is destroyed, in water-level fluctuation, will not cause heat-conducted to show stream signal meter malfunction due to internal gas flow.The utility model belongs to pipeline reliability operation field.
Description
Technical field
The utility model is related to vacuum breakdown device of vacuum in a kind of pipeline, belong to pipeline reliability operation field.
Background technology
With the extensive use of China's automation of hydropower plant original paper, ensureing each automation original paper signal installed on pipeline just
One of important topic of Que Shangsongshi hydroelectric power plants, traditional mounting means, which is easy to cause in pipeline, vacuum, the presence meeting of vacuum
The heat-conducted reliability shown and sent on flowmeter signal is influenced, it is heat-conducted to show that stream signal meter frequent movement involution is drawn in water-level fluctuation
Play signal wrong report.
Invention content
The purpose of this utility model is that：Vacuum breakdown device of vacuum in a kind of hydroelectric power plant's pipeline is provided, it is true to destroy channel interior
Sky in water-level fluctuation, will not cause heat-conducted to show stream signal meter malfunction due to internal gas flow.
To solve the above problems, intending using vacuum breakdown device of vacuum in such a hydroelectric power plant's pipeline, the pipeline includes skill
Art water supply and drainage manifold and cooling water drainage water pipe, the Upstream section of the water outlet of cooling water drainage water pipe with technical water supply main sewer
It connects, ventilation is also provided with and communicated at the downstream of the technical water supply main sewer at the place that is connected with the water outlet of cooling water drainage water pipe
Pipe is provided with check valve, i.e. non-return valve, alternatively referred to as one-way gas-compensating valve on snorkel, to realize through snorkel to technical water supply
One-way ventilating in main sewer.
In aforementioned device, cooling water drainage water pipe include upper oil guide groove cooling water drainage water pipe, lower oil guide groove cooling water drainage water pipe,
Water oil guide groove cooling water drainage water pipe, air-cooled oil groove cooling water drainage water pipe and thrust bearing oil sump cooling water drainage water pipe.
When vacuum occurs for channel interior, check valve both sides generate pressure differential, will make inside external gas suction pipe road
Channel interior air pressure is identical with atmospheric pressure, and in water-level fluctuation, the gas of channel interior will not change with the fluctuation of water level,
Guarantee cause it is heat-conducted show stream signal meter correctly act.
Compared with prior art, the advantage of this system is as follows：
The pipeline vacuum breakdown device of vacuum can be effectively improved the heat-conducted running environment for showing stream signalling means, prevent technical water supply
It is heat-conducted to show that stream signal meter correctly acts there are vacuum in drainpipe, improve it is heat-conducted show sent on stream signalling means signal it is reliable
Property, the data volume of hydroelectric power plant's host computer monitoring is reduced, operations staff is improved and monitors quality；Pipeline vacuum breakdown device of vacuum is in pipeline
Inside there is a situation where vacuum, make its internal formation negative pressure, check valve both sides form differential pressure, make to reach inside extraneous air suction line
To balance, when inside water pressure is more than external air pressure, which will not act.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
It, below will be by attached drawing to utility model to make the purpose of this utility model, technical solution and advantage clearer
It is described in further detail.
Embodiment：
With reference to attached drawing 1, vacuum breakdown device of vacuum in a kind of hydroelectric power plant's pipeline is present embodiments provided, the pipeline includes technology
Water supply and drainage manifold 1 and cooling water drainage water pipe 2, the upstream of the water outlet of cooling water drainage water pipe 2 with technical water supply main sewer 1
Duan Liantong is also provided with and communicated at the downstream of the technical water supply main sewer 1 at the place that is connected with the water outlet of cooling water drainage water pipe 2
Snorkel 3 is provided with check valve 4, alternatively referred to as one-way gas-compensating valve on snorkel 3, is arranged with realizing through snorkel 3 to technical water supply
One-way ventilating in supply mains 1 is provided with cooling water drainage water pipe on cooling water drainage water pipe 2 and shows stream signalling means 5, in Fig. 1, cooling water drainage
Water pipe 2 is followed successively by oil guide groove cooling water drainage water pipe, lower oil guide groove cooling water drainage water pipe, water oil guide groove cooling water drainage from left to right
Water pipe, air-cooled oil groove cooling water drainage water pipe and thrust bearing oil sump cooling water drainage water pipe, be correspondingly arranged on each drainpipe there are one
Cooling water drainage water pipe shows stream signalling means 5.
When vacuum occurs for channel interior, 4 both sides of check valve generate pressure differential, will make inside external gas suction pipe road
Channel interior air pressure is identical with atmospheric pressure, and in water-level fluctuation, the gas of channel interior will not change with the fluctuation of water level,
Guarantee cause it is heat-conducted show stream signal meter correctly act.
