Abstract
The utility model belongs to a device which is used together with a reciprocating pump, and in particular relates to a pressure buffer, including a buffer barrel body, a plunger and a sealing ring. The buffer barrel body is provided with an intake pipe and an outtake pipe, and the sealing ring is positioned between the inner wall of the buffer barrel body and the plunger which is communicated with the internal cavity of the buffer barrel body. The utility model is characterized in that: the buffer barrel body is provided with a pressing plate, with the buffer barrel body connected with the pressing plate through a pulling pole; the external end of the plunger matches with the pressing plate; a spring is arranged between the pressing plate and the buffer barrel body and presses the plunger. The utility model has the advantages of simple structure, convenient use, and remarkable buffer result, thus creating condition for the high quality of a project.
Description
Technical field
The utility model belongs to a kind of and the matching used device of reciprocating pump, particularly relates to a kind of pressure buffer.
Background technique
In background technique, Hydraulic and Hydro-Power Engineering need use the striaght cement slurries that hydraulic structure etc. is carried out the injection grout construction, adopt reciprocating pump grouting mostly, reciprocating pump is mainly by the pump housing, reciprocating piston, seal arrangement, and stock inlet and grout outlet, the instantaneous flow during reciprocating pump work is normally pulsed, and causes output slurries pressure transient in the pipeline, easily cause the construction quality defective, be difficult to satisfy construction requirement.
Summary of the invention
The inhomogeneous pressure surge that causes of fluid flow designs the utility model in the pipeline in order to solve, its technical solution is such: it comprises buffering cylindrical shell, plunger, seal ring, the buffering cylindrical shell is provided with inlet tube and outer pipe, described seal ring is arranged between buffering cylinder inboard wall and the plunger, described plunger communicates with the dsah-pot intracoelomic cavity, it is characterized in that on the described buffering cylindrical shell pressing plate being housed, both are connected by pull bar, can match with pressing plate in the outer end of plunger, be provided with spring between pressing plate and buffering cylindrical shell, spring is pressed on the plunger.The utility model is simple in structure, easy to use, and cushioning effect is obvious.Because the structure that has adopted spring to match with plunger can be utilized the compression of spring and answer to store or emit a part of slurries, thereby can reduce the inhomogeneous pressure surge that causes of slurry flow in the pipeline, has created condition for improving construction quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Concrete thing is executed mode
In Fig. 1, the utility model comprises buffering cylindrical shell 1, plunger 4, seal ring 5, buffering cylindrical shell 1 is provided with inlet tube 2 and outer pipe 3, described seal ring 5 is arranged between buffering cylindrical shell 1 inwall and the plunger 4, and described plunger 4 communicates with buffering cylindrical shell 1 inner chamber, on the described buffering cylindrical shell 1 pressing plate 8 is housed, both are connected by pull bar 7, can match with pressing plate 8 in the outer end of plunger 4, be provided with spring 6 between pressing plate 8 and buffering cylindrical shell 1, and spring 6 is pressed on the plunger 4.
When the utility model used, inlet tube 2 joined with the slurries transfer pump, and outer pipe 3 joins with the slurries delivery pipe.When the instantaneous flow of slurries is greater than mean flowrate in transfer pump pumps into buffering cylindrical shell 1, head pressure rises, make on the plunger 4 and move, spring 6 is compressed, slurries amount in the buffering cylindrical shell 1 increases, this has just deposited the part of the instantaneous flow that pumps in buffering cylindrical shell 1 inner chamber, the instantaneous slurry flow that feasible instantaneous slurry flow of discharging outer pipe 3 enters less than inlet tube 2; When instantaneous flow during less than mean flowrate, head pressure descends, and plunger 4 moves down, and spring 6 is replied, and the Fluid Volume in the buffering cylindrical shell 1 reduces, the instantaneous slurry flow that the instantaneous slurry flow at outer pipe 3 places is entered greater than inlet tube 2.Because the structure that has adopted spring to match with plunger can be utilized the compression of spring and answer to store or emit a part of slurries, thereby can reduce the inhomogeneous pressure surge that causes of slurry flow in the pipeline, has created condition for improving construction quality.
