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 that connect soon the submerged pipe pump, especially a kind of submerged pipe pump check valve assembly that connects soon.
Background technique
The submerged pipe pump is used for that hollow hole temporary drainage, eminence are poured water temporarily, pipe pressurizing, when single pump promotes lift when inadequate, pump lifting height or fed distance that easily occasional combination serial connection is same.Available woven-jacket hose is organized into groups connection fast, is used for drainage underground, the irrigation of going up a hill.The high-pressure multi-stage pump of alternative heaviness and supporting Steel Tube Special are connected loaded down with trivial details connection with pipeline, otherwise really can't be for it.Specialization can need not hanging device in a short period of time just can organize draining fast, is used for mine perviousness and speedily carries out rescue work, and strives for life time, particularly suitable.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of submerged pipe pump check valve assembly that connects soon simple and reasonable for structure, easy to use is provided.
According to technological scheme provided by the invention, the described submerged pipe pump check valve assembly that connects soon, it comprises tapered interior girth sheets, outward edge at interior girth sheets is connected with outer girth sheets, middle part at interior girth sheets has through hole, be fixed with at least three at the left side wall of interior girth sheets and draw ear, be fixed with at least three guide rods at the inner conical surface of interior girth sheets, draw at each all to be connected with extension spring on the ear.
Described interior girth sheets is conical, and the outer girth sheets that one is connected on the outward edge of interior girth sheets is ring, and the summit of interior girth sheets place circular cone is positioned at the right side of outer girth sheets, and the plane, place, left side of outer girth sheets is perpendicular to the axis of interior girth sheets.
Described guide rod is arranged on equably near on the interior girth sheets of through hole perisporium position.
Described drawing on the medium position that ear evenly is 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.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
As shown in the figure, this connects submerged pipe pump check valve assembly soon, it comprises tapered interior girth sheets 1.1, outward edge at interior girth sheets 1.1 is connected with outer girth sheets 1.2, has through hole 1.6 at the middle part of interior girth sheets 1.1, be fixed with at least three at the left side wall of interior girth sheets 1.1 and draw ear 1.3, be fixed with at least three guide rods 1.4 at the inner conical surface of interior girth sheets 1.1, draw at each all to be connected with extension spring 1.5 on the ear 1.3.
Described interior girth sheets 1.1 is conical, the outer girth sheets 1.2 that one is connected on the outward edge of interior girth sheets 1.1 is ring, the summit of interior girth sheets 1.1 place circular cones is positioned at the right side of outer girth sheets 1.2, and the plane, place, left side of outer girth sheets 1.2 is perpendicular to the axis of interior girth sheets 1.1.
Described guide rod 1.4 is arranged on equably near on the interior girth sheets 1.1 of through hole 1.6 perisporium positions.
Described drawing on the medium position that ear 1.3 evenly is fixed on interior girth sheets 1.1 left side walls.
During use, the other end of extension spring 1.5 is connected on the short-range missile leaf, the oil-filled type motor is fixed in the water pump cover, guide rod 1.4 more than three is enclosed within on the shell of oil-filled type motor and slides, check valve assembly of the present invention is led, and the left side of outer girth sheets 1.2 cooperates with non-return end face on the water pump cover.
If guide rod 1.4 is three, the central angle between adjacent two guide rods 1.4 differs 120 °; If draw ear 1.3 also to be three this moment, then adjacent two are drawn the central angle between the ear 1.3 to differ 120 °, and guide rod 1.4 and its close central angle between the ear 1.3 that draws differ 60 °.
