Abstract
The utility model relates to a ceramic straight one-way valve for a chemical grouting pump. The ceramic straight one-way valve is characterized in that a valve core (2) is positioned in a cylindrical inner cavity of a valve body (1), and a retainer ring (3) is positioned on the upper part of the valve body (1). The ceramic straight one-way valve for the chemical grouting pump is suitable for high-viscosity fluid such as glue.
Description
Technical field
The utility model relates to a kind of one-way valve, relates in particular to a kind of ceramic-type inline check valve that is used for chemical grouting pump.
Background technique
The chemical grouting pump principle is seen Fig. 2, and when piston moved right under external force, pump chamber was negative pressure state, and the sizing material of hopper under atmospheric pressure gets into the import one-way valve, gets into piston cavity then, and export one-way valve and under atmospheric pressure close this moment; When piston is moved to the left under external force; Sizing material in the material chamber is under pressure, and sealing import one-way valve squeezes and leaves a mouthful one-way valve; Sizing material gets into working pipe; It is thus clear that the sealability of the one-way valve of chemical grouting pump and sizing material fluency (pressure loss that is it is little) within it, generally we adopt the one-way valve that hydraulic transmission is used, and see " hydrovalve principle, O&M " P42 of Chemical Industry Press and industrial equipment and information engineering publishing centre 2005 publishing, 43 pages.
Traditional one-way valve is the steel ball type inline check valve, high viscosity fluids such as the inapplicable sizing material class of this one-way valve; So we need the one-way valve of grouting pump it is transformed.
The model utility content
The purpose of the utility model provides the ceramic-type inline check valve that is used for chemical grouting pump that is applicable to high viscosity fluids such as sizing material class.
For realizing above purpose, the technological scheme that the utility model adopts: a kind of ceramic-type inline check valve that is used for chemical grouting pump, it comprises valve body (1), spool (2) and back-up ring (3); It is characterized in that described spool (2) is positioned at the cylindrical cavity of valve body (1), back-up ring (3) is positioned at the top of valve body (1).
The diameter of the material feeding mouth of described valve body (1) is less than the discharge port diameter.
Described spool (2) is a spheres of ceramic.
The beneficial effect of the utility model: through using practice, it is little to the utlity model has the pressure loss, and flow is big, is quick on the draw, and reliability is high.Because the spool of ceramic ball is nonmagnetic, can not adsorb the ferromagnetism impurity in the sizing material during grouting, good sealing effect, hardness is high, and it is little to wear and tear, and the life-span is long.
Description of drawings
Fig. 1 is the assembling schematic representation of the utility model;
Fig. 2 is traditional chemical grouting pump schematic diagram.
Valve body in the drawings, 1; 2, spool; 3, back-up ring; P1, feedstock direction; P2, discharging direction.
Embodiment
With regard to accompanying drawing the utility model is described further below, to help understanding the utility model content.
As shown in Figure 1, the assembly relation of the utility model is: described spool 2 is positioned at the cylindrical cavity of valve body 1, and back-up ring 3 is positioned at the top of valve body 1.
The diameter of the material feeding mouth of described valve body 1 is less than the discharge port diameter.
Effect as shown in Figure 1, that various piece is brought into play in practical work process among the figure: spool 2 changes high-precision ceramic balls into by former steel ball; In order to reduce the pressure loss, remove spring, adopt vertically and place, spool 2 leans on gravity reduction; Be enlargement discharge, guarantee the sealing of spool 2 simultaneously, valve body 1 side direction fluting.Slurries are from the inner chamber of feedstock direction P1 entering valve body in real work, and slurries flow out from discharging direction P2.
More than the ceramic-type inline check valve that is used for chemical grouting pump that the utility model provided has been carried out detailed introduction; Used concrete example among this paper the principle and the mode of execution of the utility model are set forth, above embodiment's explanation just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (3)
1. ceramic-type inline check valve that is used for chemical grouting pump, it comprises valve body (1), spool (2) and back-up ring (3); It is characterized in that described spool (2) is positioned at the cylindrical cavity of valve body (1), back-up ring (3) is positioned at the top of valve body (1).
2. the ceramic-type inline check valve that is used for chemical grouting pump according to claim 1, the diameter of material feeding mouth that it is characterized in that described valve body (1) is less than the discharge port diameter.
