The specific embodiment
One basic structure of the present invention
As shown in Figure 1, the present invention is connected with pump suction attachment seat 2, is constituted suction line 1 through pump chamber inlet hole k and pump work chamber N connection by suction pipe, sucks one way valve 3 and is installed on the suction line 1, constitutes unidirectional suction line; Shutoff 8, discharge pipe and pump are discharged plinth 6 and are connected through pump chamber tap T and pump work chamber N connection formation discharge line 7, discharge one way valve 5 and are installed in the unidirectional discharge line of formation on the discharge line 7; Deformation shutoff 8 sealing shrouds are contained in unidirectional discharge line outlet section and the tight socket of plugging wall; The plugging chamber Q that shutoff 8, unidirectional discharge line and discharge one way valve 5, plugging wall, obstruction S constitute is a closed chamber.Pump 4 works done suck low pressure liquid or gas through unidirectional suction line, obtain high pressure behind the N of pump work chamber, through discharging one way valve 5, are discharged to airtight plugging chamber Q.According to Pascal's law: be added in the pressure on the enclosed liquid, can size unchangeably by liquid to all directions transmission, obstruction S can be under pressure, outwards motion.Pump 4 continuous doing works, plugging chamber Q inner high voltage liquid or gas constantly increase, until obstruction S is discharged.
On unidirectional discharge line, a pressure indicator H and pump line chamber are housed are communicated with, when the plugging chamber is dredged, pressure will become zero.
Two the present invention adopt the basic structure of manual Piston Reciprocating Pump
As shown in Figure 2, comprise piston rod 411, piston 412, seal 412a, piston rod 413, end cap 414, upper handle 415A, lower handle 415B, tee junction seat 64, have pump chamber inlet hole K and pump chamber outlet opening T on the tee junction seat 64, suction pipe 13 is communicated with by pump suction attachment seat 2, pump chamber intake K and working chamber N, constitutes suction line 1, sucks one way valve 3 and is installed on the pump suction attachment seat 2; Discharge pipe 71 is discharged plinth 64 by pump, and pump chamber tap T and working chamber N are communicated with, and constitutes discharge line 7, discharges one way valve 5 and is installed in tee junction seat 64 taps.Elastic deformation shutoff 81 is sleeved on the discharge pipe 71 by plugging Connection Block 72.Like this, suction line 1 sucks one way valve 3, and syringe 41 is discharged one way valve 5, discharge line 7, and complete manual Piston Reciprocating Pump formula dredging device has just been formed in shutoff 81.
During application, will be with the suction inlet seat 11 of slipping through the net to put into basin W, block head 81 is blocked the mouth of pipe that is blocked, holding lower handle 415B, to compress shutoff 81 motionless, twitches upper handle 415A and drive piston rod 411 piston 412 is moved back and forth in piston rod 413.When piston 412 and piston rod 413 reverse motions arrived the top, working chamber N volume increased, and sucked one way valve 3 and opened, and discharged one way valve 5 and closed, and working chamber N sucks water from basin; When piston 412 moved to the bottom with piston rod 413 relatively, working chamber N volume diminished, and sucked one way valve 3 and closed, and discharged one way valve 5 and opened, and the water in the working chamber N enters in the Q of plugging chamber by discharge road 7.Plugging chamber Q, shutoff 81, discharge line and discharge one way valve 5, obstruction S constitutes annular seal space.According to Pascal's theorem, handle pressure through piston pump 41, is converted into hydraulic coupling, is delivered on the obstruction S.Handle 415A moves reciprocatingly continuously, and suction line 1 and discharge line 7 suck and discharge water continuously, and plugging chamber Q water constantly increases, because liquid is incompressible, obstruction S pressurized is motion outwards, and is loosening up to obstruction S and tube wall.At this moment, the plugging cavity pressure reduces, and accelerates piston movement speed, can strengthen the fluid flow in plugging chamber, and obstruction is subjected to the frictional force effect of water, with water movement, outside being rushed out pipe.
Intake duct and water tap L are joined, utilize tap water, can strengthen fluid flow, adapt to obstruction from the long situation of the mouth of pipe.
