Abstract

The utility model discloses a circulation pump line, it includes installs inlet three -way pipe and the water outlet tee coupling on circulation pipeline, be connected with circulating pump and bypass pipe between inlet three -way pipe and the water outlet tee coupling respectively, be equipped with direct -acting electromagnetic valve on the connecting tube between circulating pump and the inlet three -way pipe, be equipped with the relief valve on the connecting tube between direct -acting electromagnetic valve and the inlet three -way pipe, be equipped with the check valve on the bypass pipe. When circulating pump abrupt halt during operation, the impact of rivers to the circulating pump has been alleviated from the bypass pipe outflow to partial rivers to avoid water hammer, water hammer phenomenon's emergence, has prolonged the life of circulating pump, the utility model discloses simple structure, good reliability.

Description

Circulation pump conduit
Technical field
This utility model is related to a kind of thermal power plant unit equipment, especially a kind of circulation pump conduit.
Background technology
In thermal power plant unit, the effect of circulating pump is the power providing secondary cycle water, so that the water in unit secondary side is flowed Come, thus carrying out heat exchange with the water in primary side in heat exchanger.The secondary side current of existing unit all flow into circulation Pump, does not install bypass circulation additional.So when system leads to circulating pump to stop suddenly work in power-off or the impact of other external factor When making, the water in system can be moved forward due to due to inertia, and current are very big to the impulsive force of circulating pump, meeting when serious There is water attack, water hammer, damage circulating pump.
Content of the invention
The technical problems to be solved in the utility model be provide that a kind of structure is simple, working stability and highly reliable circulation Pump conduit.
In order to solve above-mentioned technical problem, this utility model includes the inlet triplet for water being arranged on circulation line and water outlet three Logical, be connected to circulating pump and bypass pipe between described inlet triplet for water and outlet three way, described circulating pump and inlet triplet for water it Between connecting pipe be provided with direct-acting electromagnetic valve, the connecting pipe between described direct-acting electromagnetic valve and inlet triplet for water is provided with Relief valve, described bypass pipe is provided with check valve.
Described bypass pipe includes the first pipeline and the second pipeline, and the internal diameter of described first pipeline is less than the interior of the second pipeline Footpath, described first pipeline one end is connected with inlet triplet for water, and the other end is connected with the water inlet end of check valve, described second pipeline one end Connect with the water side of check valve, the other end is connected with outlet three way.
The beneficial effects of the utility model are: when circulating pump quits work suddenly, part current flow out from bypass pipe, delay Solving the impact to circulating pump for the current, thus avoiding the generation of water attack, water hammer, having extended the service life of circulating pump, This utility model structure is simple, highly reliable.
Brief description
Fig. 1 circulates the structural representation of pump conduit for this utility model.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail:
Referring to Fig. 1, circulation pump conduit of the present utility model includes the inlet triplet for water 1 being arranged on circulation line and water outlet three Logical 2, it is connected to circulating pump 3 and bypass pipe, described circulating pump 3 and water inlet three between described inlet triplet for water 1 and outlet three way 2 Connecting pipe between logical 1 is provided with direct-acting electromagnetic valve 4, the connecting tube between described direct-acting electromagnetic valve 4 and inlet triplet for water 1 Road is provided with relief valve 5, and described bypass pipe is provided with check valve 6.After system cut-off, circulating pump 3 quits work suddenly, now directly Type solenoid valve 4 closes the pipeline between circulating pump 3 and inlet triplet for water 1 because of power-off, and current then can flow to bypass pipe, bypass pipe On check valve 6 open and direct water flow towards outlet three way 2, alleviate the impact to circulating pump for the current, thus avoiding water attack, water The generation of hammer phenomenon, extends the service life of circulating pump;If the moment closed in direct-acting electromagnetic valve 4, direct driving type electromagnetic Produce on pipeline between valve 4 and inlet triplet for water 1 and suppress, can discharge from relief valve 5, and then protect current to direct drive type electro The impact of magnet valve 4.
Described bypass pipe includes the first pipeline 7 and the second pipeline 8, and the internal diameter of described first pipeline 7 is less than the second pipeline 8 Internal diameter, described first pipeline 7 one end connected with inlet triplet for water 1, and the other end is connected with the water inlet end of check valve 6, described second Pipeline 8 one end is connected with the water side of check valve 6, and the other end is connected with outlet three way 2.Such be designed with quick beneficial to current Ground is discharged in outlet three way 2 through bypass pipe.
In sum, content of the present utility model is not limited in the above embodiments, and those skilled in the art can To propose other embodiments within technological guidance's thought of the present utility model, but these embodiments are included in this practicality newly Within the scope of type.
