Abstract
The invention relates to a check valve assembly for a rapid-connection submersible pipeline pump, which comprises a tapered inner ring plate, wherein an outer edge of the inner ring plate is integrally connected with an outer ring plate; a through hole is formed in the middle of the inner ring plate; at least three pull lugs are fixed in a left side wall of the inner ring plate; at least three guide rods are fixed on an inner conical surface of the inner ring plate; and each pull lug is connected with a tension spring. The check valve assembly has the advantages that the check valve assembly is simple in structure, reasonable and convenient to use.
Description
Technical field
The present invention relates to a kind of parts connecing submerged pipe pump soon, especially one connects submerged pipe pump check valve assembly soon.
Background technology
Submerged pipe pump is used for hollow hole temporary drainage, eminence is poured water temporarily, pipe pressurizing, when single pump lifting lift is inadequate, occasional combination easily can be connected in series same pump hoisting depth or fed distance.Available woven-jacket hose organizes into groups connection fast, for drainage underground, irrigation of going up a hill.The loaded down with trivial details connection of the high-pressure multi-stage pump of alternative heaviness and supporting Steel Tube Special and pipeline, on the contrary really cannot for it.Special feature in a short period of time without the need to hanging device just energy rapid tissue draining, can be speedily carried out rescue work for mine perviousness, strives for life time, particularly suitable.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and simple and reasonable for structure, easy to use connect submerged pipe pump check valve assembly soon.
According to technical scheme provided by the invention, describedly connect submerged pipe pump check valve assembly soon, it comprises tapered interior girth sheets, the outward flange of interior girth sheets is connected with outer girth sheets, at the middle part of interior girth sheets, there is through hole, the left side wall of interior girth sheets is fixed with at least three and draws ear, the inner conical surface of interior girth sheets is fixed with at least three guide posts, be all connected with extension spring each drawing on ear.
Described interior girth sheets is conical, and the outer girth sheets be integrally connected on the outward flange of interior girth sheets is annular, and the summit of interior girth sheets place circular cone is positioned at the right side of outer girth sheets, and place, the left side plane orthogonal of outer girth sheets is in the axis of interior girth sheets.
Described guide post is arranged on equably on the interior girth sheets of through hole perisporium position.
On the described medium position drawing ear to be evenly fixed on interior girth sheets left side wall.
The present invention has the advantages such as simple and reasonable for structure and easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
As shown in the figure, this connects submerged pipe pump check valve assembly soon, it comprises tapered interior girth sheets 1.1, the outward flange of interior girth sheets 1.1 is connected with outer girth sheets 1.2, at the middle part of interior girth sheets 1.1, there is through hole 1.6, the left side wall of interior girth sheets 1.1 is fixed with at least three and draws ear 1.3, the inner conical surface of interior girth sheets 1.1 is fixed with at least three guide posts 1.4, be all connected with extension spring 1.5 each drawing on ear 1.3.
Described interior girth sheets 1.1 is conical, the outer girth sheets 1.2 be integrally connected on the outward flange of interior girth sheets 1.1 is annular, the summit of interior girth sheets 1.1 place circular cone is positioned at the right side of outer girth sheets 1.2, and place, the left side plane orthogonal of outer girth sheets 1.2 is in the axis of interior girth sheets 1.1.
Described guide post 1.4 is arranged on equably on the interior girth sheets 1.1 of through hole 1.6 perisporium position.
On the described medium position drawing ear 1.3 to be evenly fixed on interior girth sheets 1.1 left side wall.
During use, the other end of extension spring 1.5 is connected on short-range missile leaf, filling type motor is fixed in water pump cover, the shell that the guide post 1.4 of more than three is enclosed within filling type motor slides, lead to check valve assembly of the present invention, the left side of outer girth sheets 1.2 coordinates with the non-return end face on water pump cover.
If guide post 1.4 is three, the central angle between adjacent two guide posts 1.4 differs 120 °; If now draw ear 1.3 to be also three, then adjacent two are drawn the central angle between ear 1.3 to differ 120 °, and guide post 1.4 draw central angle ear 1.3 between close with it differs 60 °.
