Abstract
The utility model discloses a one-way valve, which comprises a valve body and a valve cap; a valve core is arranged in the space formed by the valve body and the valve cap; the valve body adopts a tubular structure; and one end of the valve body extends inwards to form a valve bottom with a central hole, and an annular inner flange arranged at the other end is matched and connected with the valve cap. The one-way of the utility model is thin-walled and simple in the integral structure, and realizes light weight and low cost in manufacturing.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of one-way valve.
Background technique
The existing one-way valve that is used for on-off action is of a great variety, and structure also is varied, and along with the development of economic technology, the energy saving of product, Security, low-carbon (LC) more and more highlight.One-way valve has purposes widely on products such as machinery, pipeline, aviation, vehicle, especially the huge slight improvement of his usage quantity just can produce huge economic benefit, particularly the miniaturization of one-way valve structures can be saved a large amount of materials, reduces manufacturing, sales cost.
Summary of the invention
The utility model provides a kind of one-way valve of simple in structure, low cost of manufacture.
A kind of one-way valve comprises valve body and valve gap, is provided with spool in the space that valve body and valve gap constitute, and described valve body is a tubular structure, and valve body one end extends internally and constitutes at the bottom of the valve of band center hole, and the other end is provided with the annular inward flange valve gap that is connected.The realization that this kind is the most succinct the function of one-way valve, the valve overall structure is thin-walled, and is succinct on overall structure, realizes on the weight that lightweight, particularly valve body, valve gap, spool are plastic material.
Be provided with diaphragm in the middle of the described spool, both sides, diaphragm center are extended with the center valve rod.
Be provided with annular protrusion near spool one side at the bottom of the described valve, opposite side is provided with the loss of weight scrobicular ring, further reduces weight and cost.
Be provided with seal ring between the diaphragm of described spool and the annular protrusion at the bottom of the valve.Be provided with spring between described valve gap and the spool.Spring is that compression spring compressing diaphragm seal connects seal ring, realizes the unidirectional function of passing through.
The utility model is realized lightweight and the low cost made by the succinct linkage structure of tubular structure valve body, valve gap, spool.
Description of drawings
Fig. 1 is that the utility model one-way valve master looks the sectional structure schematic representation.
Embodiment
