Abstract
The utility model discloses a check valve, the structure of which mainly comprises a valve body, valve clacks, a spring and a stop piece, wherein the valve clacks arranged in the valve body are connected with the spring, and then the stop piece stops the spring; the stop piece is connected with a fixed column; the fixed column is arranged in the valve body by adopting an embedded manner; and the stop piece is also connected on the fixed pillar by adopting the embedded manner in the valve body. The check valve adopts the embedded installation manner, therefore, when in assembly, no bolts are needed, a special clamp is used for embedding the stop piece in the valve body, and then slightly prying the piece edge of the stop piece which is provided with a positioning groove, thus achieving the positioning effect, leading to simple assembly, being more firm, and leading to higher sealing performance and long service life. As needing no fastening bolts, the positioning column can be slightly narrow, thus lowering the production cost.
Description
Technical field
The utility model relates to safety check, the safety check of specifically a kind ofly be convenient to install, reduce cost, the life-span is long.
Background technique
In existing like product, safety check is to be widely used, and can be applicable to all trades and professions, Just because of this, the various safety check that can solve certain problem or have certain function go out at the sound, and are connected with screw between the retaining sheet in the safety check of prior art, spring, flap, locating column, and its deficiency is, screw in use, loosening easily, strengthen the friction rate between parts, reduce working life, often maintenance, extremely inconvenience.And operation is loaded down with trivial details during assembling, is not easy to install; During installation, locating column need increase cost with set screw.
The model utility content
(1) technical problem that will solve
The utility model is the defective that exists at prior art, and a kind of safety check is provided, solved that the safety check of prior art exists insecure, inconvenience, low, defect of high cost of life-span be installed.
(2) technological scheme
