Abstract
The utility model discloses a check valve that makes use of the taper of a valve core and spring return to seal, comprising a liquid inlet, a liquid outlet, a valve body and a valve core. The utility model is mainly characterized in that: a spring is arranged in the valve body and one end of the spring is positioned at a spring seat of the valve core; the inner circumference of the valve body is provided with stiffeners that are evenly distributed; the liquid inlet of the valve body is provided with a traveling nut; the gap between adjacent stiffeners becomes a liquid channel when the valve door is opened. The check valve produced according to the design theme of the utility model has good seal, reliability and safety and can bring positive application effect in various liquid pipes.
Description
Technical field
The utility model relates to a kind of improvement invention of one-way valve, particularly be the invention of a kind of spring return one-way valve of unidirectional conveying liquid.
Background technique
In the prior art, one-way valve extensively adopts in liquid (as water, alcohol, oil) is carried, but the one-way valve of known technology all is to adopt magnetic sheet by plane sealing, and back of long duration like this influences the sealability of valve, causes the damage of valve body to reveal.
Summary of the invention
Problem in view of the known technology existence, the purpose of this utility model aims to provide a kind of safe and reliable, rational in infrastructure, the one-way valve that sealability is stronger, the utility model is that following mode is finished, this one-way valve, include liquid entering hole, liquid outlet, it is characterized in that being provided with spring in the described valve body, one end of described spring is installed on the spring seat of spool, spool becomes cone-shape, the inner circumference of described valve body is provided with the stiffening rib of even cloth, the liquid entering hole place of described valve body is provided with traveling nut, and the gap between the described adjacent stiffening rib becomes liquid chunnel when valve opening, be provided with seal washer in the described valve body, the utility model is rational in infrastructure, easy to use, sealability is strong, and the one-way valve made according to the utility model design motif will bring positive using effect to users.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Number in the figure: 8 is seal washer.
Specific embodiment
Accompanying drawing has been represented structure of the present utility model and embodiment, further describe the relevant details of embodiment below more in conjunction with the accompanying drawings, this one-way valve includes liquid entering hole 1, liquid outlet 5, valve body 6 and spool 2, be provided with spring 3 in the described valve body 6, one end of described spring 3 is installed on the spring seat of spool 2, the inner circumference of described valve body 6 is provided with the stiffening rib 4 of even cloth, liquid entering hole 1 place of described valve body 6 is provided with traveling nut 7, so that install, gap between the described adjacent stiffening rib becomes liquid chunnel when valve opening, when valve closing, spring 3 is in normally, when opening cock, because fluid pressure directly acts on spool 2, to the spring 3 that is connected with spool 2 is compressed, thereby open valve, liquid stream promptly flows out by the gap between the adjacent stiffening rib, when closing cock, hydrodynamic pressure keeps balance, spring reset, cone spool closes dead valve.According to the one-way valve of the utility model design motif made, sealability is strong, safe and reliable, will produce positive using effect on each fluid line.
Claims (2)
1, a kind of one-way valve, include liquid entering hole (1), liquid outlet (5), valve body (6) and spool (2), it is characterized in that being provided with in the described valve body (6) spring (3), one end of described spring (3) is installed on the spring seat of spool (2), the inner circumference of described valve body (6) is provided with the stiffening rib (4) of even cloth, the liquid entering hole (1) of described valve body (6) locates to be provided with traveling nut (7), and the gap between the described adjacent stiffening rib becomes liquid chunnel when valve opening.
