Abstract
The utility model relates to a one-way valve for conveying clear water or mortar. The one-way valve mainly solves the technical problems that the prior art has complicated structure and serious abrasion when conveyed liquid contains sand and mud. The one-way valve is characterized in that a valve core reset mechanism of the prior art is omitted, a valve core is a steel ball wrapped with elastic rubber, and an outlet of a valve body can be made into different shapes according to use conditions. With the characteristics of simple structure, low cost, wide range of application, etc., the utility model can be widely used for conveying clear water or mortar.
Description
The utility model belongs to a kind of valve, particularly relates to a kind of one-way valve.
The one-way valve of prior art, spool all have spring or other resetting-mechanism in valve body, the major defect of prior art is a complex structure, the cost height, and particularly when containing silt particle in the liquid, serious wear in the valve.
The purpose of this utility model is, designs a kind of valve body and vertically installs, and saves the valve core reset mechanism in the valve, have simple in structure, easy to maintenance, can be for the novel one-way valve of carrying uses such as clear water or mortar.
The purpose of this utility model is to realize like this, change the valve body shape, valve body can have an outlet or a plurality of outlet, and spool drops on the valve core case by deadweight or reversed liquid pressure seat in valve body, and valve core case communicates with the inlet of valve body, when spool leaves valve core case, one-way valve opens, when spool is got back to valve core case, closed check valve, for reducing the wearing and tearing between spool and the valve body, with the flexible rubber of circular spool outsourcing.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing 1,2 is the utility model structural representation.
Referring to accompanying drawing 1, liquid flows into valve body (1) from inlet A, the liquid depended on pressure promotes to leave valve core case (3) with spool (2), at this moment, liquid can pass through one-way valve, when inlet A place does not have flow of liquid fashionable, spool (2) gets back on the valve core case (3) spool (2) by deadweight or reversed liquid pressure, inlet is blocked, close one-way valve, because spool (2) moves in the valve body of being everlasting (1), for the cylindrical that reduces wear at spool (2) is surrounded by elastic caoutchouc, when the outlet of one-way valve connects when uncovered, when particularly carrying mortar, on the top of valve body (1) and circumference, have a plurality of outlets for reducing resistance to flow output, when the outlet of one-way valve is connected with pipeline, referring to Fig. 2, valve body (1) has only an outlet B, position-limited lever (5) is housed on valve body (1), and position-limited lever (5) restriction spool (2) will export B and block after rising.
The utlity model has simple in structure, volume is little, cost is low, the characteristics such as not easy to wear in the easy to maintenance and valve can be for uses such as conveying clear water and mortars.
Claims (2)
1, a kind of one-way valve is made up of valve body (1), spool (2), valve core case (3), it is characterized in that:
A. described spool (2) is the steel ball that cylindrical is surrounded by elastic caoutchouc;
B. described valve core case (3) is in the below of spool (2), and communicates with inlet duct (4).
2, one-way valve according to claim 1 is characterized in that valve body (1) has outlet B on top and circumference place.
