Pipe, makes the second feed tube 8 be used as drain pipe.
As shown in Figures 2 and 3, in the present invention preferably first embodiment, pumping equipment of the invention mainly includes connecting
Circulation passage 101, pore structure 102, screwed hole 51, bolt 11, guide rod 12, sliding block 13 and spring 14.Wherein, the He of communicating passage 101
Pore structure 102 is separately positioned on dividing plate 10, and communicating passage 101 and pore structure 102 are intersecting.Preferably, communicating passage 101
Intersected vertically with pore structure 102, and communicating passage 101 passes through pore structure 102.It will be appreciated to those of skill in the art that
Communicating passage 101 is not limited only to the through-hole structure shown in Fig. 3, and it can also be by the series connection of multiple pore structures, combines
Passage.
As shown in figure 3, bolt 11 is threadedly coupled with screwed hole 51, the left end of the right-hand member and bolt 11 of guide rod 12 offsets, and leads
The right-hand member of the left end of bar 12 and sliding block 13 offsets, and the right-hand member of the left end and spring 14 of sliding block 13 offsets, the left end of spring 14 and hole
The bottom of structure 102 offsets.When bolt 11 is tightened, bolt 11 overcomes the elastic force of spring 14 by the promotion sliding block 13 of guide rod 12
It is moved to the left.As sliding block 13 is moved to the left, communicating passage 101 is gradually blocked, until being blocked completely.When bolt 11 is screwed
Song Shi, spring 14 promote sliding block 13 to drive guide rod 12 to move right, and as sliding block 13 is moved to the left, communicating passage 101 is gradual
Open, until being fully opened.
It will be appreciated to those of skill in the art that when shell and tube exchanger needs normal work, make communicating passage 101
Block, prevent first passage to be short-circuited.When shell and tube exchanger, which does not work, not to work for a long time especially, make communicating passage
101 open, so that the water in cavity volume on shell and tube exchanger left end can flow into lower cavity volume, Ran Houzai by communicating passage 101
Discharged by the discharging valve 15 connected with lower cavity volume.It effectively prevent shell and tube exchanger when not in use, upper cavity volume is with
Water in cavity volume causes to corrode to shell and tube exchanger.
In a preferred embodiment of the invention, pumping equipment also includes the first position-limit mechanism and the second position-limit mechanism, uses
In when communicating passage 101 is blocked and opened completely completely by sliding block 13, operating personnel are made to stop turning bolt 11.First limit
Position mechanism can be shown in Fig. 3, the stepped hole of the bottom of pore structure 102 or be arranged on convex in the circumference of bolt 11
Rise, when bolt 11 twists motionless, judge that communicating passage 101 blocks completely.Second position-limit mechanism can be provided in screw thread
The jump ring of the outer end of hole 51, now bolt 11 need to be configured to the diameter of threaded portion and be more than the diameter of no threaded portion, or
Person substitutes bolt 11 with hexagonal socket head plug.
As shown in figure 4, in the second embodiment of the present invention, relative to first embodiment, it is convenient to omit guide rod 12, sliding block
13 and spring 14, bolt 11 is directly controlled the break-make of communicating passage 101.When bolt 11 is tightened, communicating passage 101 is hindered
Disconnected, when bolt 11 is unscrewed, communicating passage 101 is opened.In addition, those skilled in the art can also be as needed, using it
He substitutes bolt 11 by any feasible control member, for example, plug.
In addition, those skilled in the art can also be as needed, communicating passage 101 is arranged to have threaded through hole,
Then bolt 11 is made directly to be screwed in communicating passage 101, to realize the blocking to communicating passage 101.When communicating passage 101 needs
During opening, bolt 11 need to only be turned on from communicating passage 101.
It is as shown in Figure 5, in each above-mentioned embodiment of the present invention, horizontally disposed dividing plate 10 be configured to as
Lower structure：Height on vertical direction gradually reduces along edge to communicating passage 101.Or those skilled in the art can be with
As needed, dividing plate 10 is arranged to the nonplanar structure of other forms, and the upper end of communicating passage 101 is located at dividing plate 10
At minimum point.So that water all in upper cavity volume can flow into lower cavity volume from communicating passage 101, prevent occurring water in cavity volume
The phenomenon of accumulation.
In summary, the water in Fig. 1 on shell and tube exchanger left end in cavity volume can be made by the pumping equipment of the present invention
Lower cavity volume is flowed into time when not in use in shell and tube exchanger, and then from the discharging valve 15 connected with lower cavity volume, flow direction is outer in time again
Boundary.Therefore, pumping equipment of the invention can prevent shell and tube exchanger when not in use, the water pair in upper cavity volume and lower cavity volume
Shell and tube exchanger causes to corrode.
So far, combined preferred embodiment shown in the drawings describes technical scheme, still, this area
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these embodiments.Without departing from this
On the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to correlation technique feature, these
Technical scheme after changing or replacing it is fallen within protection scope of the present invention.
