Description
Technical field
The utility model belongs to two-way liquid circulating apparatus, especially relates to a kind of single pump liquid reversing arrangement.
Background technique
Two-way liquid circulating apparatus is widely used in the liquid pipeline system, and in order to realize two-way liquid circulation function, traditional design proposal has two kinds: the one, adopt two liquid pumps, two circuits systems; The 2nd, the pipe-line system that adopts single liquid pump single tube road and a plurality of two-way valve to make up.Efficiently solve liquid circulation switching-over problem.But part still has some deficits: one is that two kinds of design proposal systems are too complicated, and cost is high; The 2nd, troublesome poeration, use inconvenience.
The model utility content
The purpose of the utility model is to the problems referred to above that exist, provide a kind of system simplification, cost low, use single pump liquid reversing arrangement easy and simple to handle.
For realizing above-mentioned purpose; The utility model adopts following technical proposals: single pump liquid reversing arrangement of the utility model; Comprise two fluid boxes and two common valves that are installed on these two fluid box bottoms; And be connected two straight-through tubes between the common valve and be installed in the recycle pump on the straight-through tube; Also comprise two T type three-way valve, two bypass tubes; Said two T type three-way valve are separately positioned on the left and right sides of recycle pump, and the straight-through Way out of these two T type three-way valve inwardly is connected through this straight-through tube with delivery outlet with the inlet opening of recycle pump respectively, and the straight-through importer of these two T type three-way valve is to outwards being connected through this straight-through tube with two common valves respectively; One end of a bypass tube is connected with the by-pass port that is positioned at this recycle pump delivery outlet one side T type three-way valve, and the other end is connected with straight-through tube between this recycle pump and this recycle pump inlet opening one side T type three-way valve; One end of another bypass tube is connected with the by-pass port that is positioned at this recycle pump inlet opening one side T type three-way valve, and the other end is connected with straight-through tube between this recycle pump and this recycle pump delivery outlet one side T type three-way valve.
As the improvement of the utility model, said two T type three-way valve adopt electric T-shaped valve.
After adopting technique scheme; The beneficial effect that single pump liquid reversing arrangement that the utility model provides has is: because said two T type three-way valve are separately positioned on the left and right sides of recycle pump; The straight-through Way out of these two T type three-way valve inwardly is connected through this straight-through tube with delivery outlet with the inlet opening of recycle pump respectively; The straight-through importer of these two T type three-way valve is to outwards being connected through this straight-through tube with two common valves respectively; One end of a bypass tube is connected with the by-pass port that is positioned at this recycle pump delivery outlet one side T type three-way valve, and the other end is connected with straight-through tube between this recycle pump and this recycle pump inlet opening one side T type three-way valve; One end of another bypass tube is connected with the by-pass port that is positioned at this recycle pump inlet opening one side T type three-way valve, and the other end is connected with straight-through tube between this recycle pump and this recycle pump delivery outlet one side T type three-way valve.When the by-pass port of controlling two T type three-way valve is in closed condition; The straight-through import of two T type three-way valve respectively and straight-through outlet separately communicate, flow to directly along inlet opening to the delivery outlet of recycle pump from the liquid of right side fluid box and flow into the left side fluid box through straight-through tube; When control two T type three-way valve straight-through outlet port in off position; The by-pass port of two T type three-way valve is opened; The by-pass port of two T type three-way valve respectively and straight-through import separately communicate; Start recycle pump; Liquid from the left side fluid box gets into the recycle pump inlet opening through straight-through import to the by-pass port that is positioned at recycle pump left side T type three-way valve through bypass tube, and the liquid that flows out from the recycle pump delivery outlet gets into the by-pass port that is positioned at recycle pump right side T type three-way valve through another bypass tube, and liquid gets into the right side fluid box from by-pass port to the straight-through import that is positioned at recycle pump right side T type three-way valve through straight-through tube again.Simple combination through single cycle pump, multiplexing straight-through tube and bypass tube, two T type three-way valve has realized the liquid circulation switching-over.Therefore, compared with prior art, reached system simplification, cost low, use effect easy and simple to handle.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in the figure; Provided the organigram of the utility model list pump liquid reversing arrangement; Comprise two fluid boxes 5 and be installed in two common valves 6 on these two fluid box 5 bottoms; And be connected two straight-through tubes 1 between the common valve 6 and be installed in the recycle pump 3 on the straight-through tube 1; Also comprise two T type three-way valve 2, two bypass tubes 4; Said two T type three-way valve 2 are separately positioned on the left and right sides of recycle pump 3, and the straight-through Way out of these two T type three-way valve 2 inwardly is connected through this straight-through tube 1 with delivery outlet with the inlet opening of recycle pump 3 respectively, and the straight-through importer of these two T type three-way valve 2 is to outwards being connected through this straight-through tube 1 with two common valves 6 respectively; One end of a bypass tube 4 is connected with the by-pass port that is positioned at this recycle pump 3 delivery outlets one side T type three-way valve 2, and the other end is connected with straight-through tube 1 between this recycle pump 3 and this recycle pump 3 inlet openings one side T type three-way valve 2; One end of another bypass tube 4 is connected with the by-pass port that is positioned at this recycle pump 3 inlet openings one side T type three-way valve 2, and the other end is connected with straight-through tube 1 between this recycle pump 3 and this recycle pump 3 delivery outlets one side T type three-way valve 2.
As the preferred embodiment of the utility model, said two T type three-way valve 2 adopt electric T-shaped valve.
The working principle of single pump liquid reversing arrangement is: when the by-pass port of controlling two T type three-way valve 2 is in closed condition; The straight-through import of two T type three-way valve 2 respectively and straight-through outlet separately communicate, flow to directly along inlet opening to the delivery outlet of recycle pump 3 from the liquid of right side fluid box 5 and flow into left side fluid box 5 through straight-through tube 1; When control two T type three-way valve 2 straight-through outlet port in off position; The by-pass port of two T type three-way valve 2 is opened; The by-pass port of two T type three-way valve 2 respectively and straight-through import separately communicate; Start recycle pump 3; Liquid from left side fluid box 5 passes through bypass tube 4 entering recycle pumps 3 inlet openings through straight-through import to the by-pass port that is positioned at recycle pump 3 left side T type three-way valve 2, and the liquid that flows out from recycle pump 3 delivery outlets gets into the by-pass port that is positioned at recycle pump 3 right side T type three-way valve 2 through another bypass tube 4, and liquid extremely leads directly to import through straight-through tube 1 entering right side fluid box 5 from the by-pass port that is positioned at recycle pump 3 right side T type three-way valve 2 again.
Two T type three-way valve 2 adopt electric T-shaped valve, just can change the pipeline liquid flow direction through the combination of two electric T-shaped valves of control and pipeline automatically, reach the purpose of liquid list pump circulation switching-over.Can in various two-way liquid circulations, promote the use of.
