Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, so that the utility model technology
Scheme is more readily understood and grasps.
In the present embodiment, it is to be understood that term " centre ", "upper", "lower", " top ", " right side ", " left end ",
" top ", " back side ", " middle part ", etc. instructions orientation or positional relationship be based on the orientation or positional relationship shown in the drawings, only
It is of the invention for ease of description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with spy
Fixed orientation construction and operation, therefore be not considered as limiting the invention.
In addition, the connection or fixed form between component if not otherwise specified in this embodiment, connection or solid
Determine mode can for fixed by bolt commonly used in the prior art or pin fix or pin shaft connection etc. modes, therefore, this
It is not described in detail in embodiment.
As shown in Figure 1, a kind of external Submersible Pump sand discharger, including it is internal be hollow setting and bottom be
The shell 1 of stacker setting, and upper cover 21 top of shell and fixed with 1 phase of shell is set, and is arranged in shell 1
And the long threaded rod 3 fixed with shell 1, be provided with nut 31 on the long threaded rod 3, the bottom of the nut 31 and shell 1 it
Between be provided with valve block unit 4；The upper end of the long threaded rod 3 is connect with upper cover 2, the lower end of the long threaded rod 3 and the bottom of shell 1
Connection, the long threaded rod 3 play the role of valve rod simultaneously；It is opening setting in the middle part of the upper cover 2, and is set in the upper end of upper cover 2
It is equipped with the upper cover short stud 21 for fixing sand discharger and water-supply-pipe；The bottom of the shell 1 is provided with for fixing sand discharger
The lower part of the shell short stud 11 of submersible pump, the shell 1 is provided with sand removing hole 12, for fine sand to be discharged.
As shown in Fig. 2, the valve block unit 4 is by the be located at lowermost end and big valve block 41 that is flexibly connected with long threaded rod 3,
And valve block valve rod 42 big 41 center of circle of valve block and fixed with big 41 phase of valve block is set, and be arranged in it is on valve block valve rod 42,
The small valve block 43 being flexibly connected with valve block valve rod 42 forms, and is provided with limited block 421, the big valve at the top of the valve block valve rod 42
Rubber parts 411 is lined with outside piece 41, the valve block unit 4 can slide up and down a distance on long threaded rod 3, and the nut 31 is used
In the sliding distance for limiting big valve block 41, the big valve block 41 is mainly responsible for the switch of sand removing hole 12, and the small valve block 43 can
A distance is slided up and down on valve block valve rod 42, the limited block 421 is used to limit the sliding distance of small valve block 43, described small
Valve block 43 is responsible for the switch between pump and water-supply-pipe.
Working principle explanation:
Two states that mechanism is divided into electric pump booting, electric pump shuts down.
Electric pump booting: as shown in figure 3, when electric pump is in the state of work, under the impact of high pressure water flow, big valve block 41
It is moved upwards with small valve block 43, small valve block 43 provides additional upward power by being mounted on the valve block valve rod 42 of big valve block 41, greatly
Valve block 41 slides into the sliding high limit position of 31 lower section of nut, and small valve block 43 slides into the sliding of 421 lower section of limited block most
Behind high limit position, electric pump is open-minded with water-supply-pipe, and water flow is flowed away by water-supply-pipe, meanwhile, the rubber parts 411 of big 41 outer lining of valve block
It can just be located in same level with the sand removing hole 12 of 1 lower part of shell, sand removing hole 12 can be blocked, it is real under the pressure of water flow
It now seals, water flow is avoided to flow away from sand removing hole 12.
Electric pump shutdown: as shown in figure 4, after electric pump shutdown, because of the pressure of return water, big valve block 41 and small valve block 43 are all downwards
Sliding, until big valve block 41 slips down to the sliding lowest limit position of 1 bottom of shell, small valve block 43 slips down to big 41 top of valve block
Sliding lowest limit position, the water outlet of water pump can be sealed, so that the return water containing sand is cannot be introduced into the excessively stream part of water pump, together
When, after big valve block 41 and small valve block 43 all slip down to extreme lower position, the sand removing hole 12 of 1 lower part of shell is no longer by rubber parts 411
Blocking, then the fine sand in return water can be discharged from sand removing hole 12.
The utility model has the following beneficial effects: water pump, in operating status, large and small valve block slides up to extreme position,
The rubber parts of big valve block outer lining blocks sand removing hole, and sealing function is realized under the pressure of water, after closing pump, size valve block slide downward
To extreme position, sand removing hole is opened, and sand discharge avoids the case where precipitating because of sand, cause pump that can not operate, to avoid
Well is mentioned due to pump can not operate, or because pump can not operate the case where causing motor to burn, and mechanism movable part is few, owns
The movement of valve block does not need exterior power all by the pressure-driven of water.Structure is simple, and manufacture, maintenance cost are low.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
