Abstract
The utility model discloses a reducing check valve body which comprises a cylinder body, wherein one part of an inner cavity of the cylinder body is a large-diameter inner cavity, the other part of the inner cavity of the cylinder body is a small-diameter inner cavity communicated with the large-diameter inner cavity, internal threads are arranged on end parts of the large-diameter inner cavity and the small-diameter inner cavity, and an openable through hole as an exhaust hole is arranged in the cylinder body. The reducing check valve body has the advantages of simple structure, small volume, convenience for installation and use, investment saving, and integration of a reducing joint and a check valve.
Description
Technical field
The utility model relates generally to technical field, relates in particular to a kind of reducing check valve body.
Background technique
Reducing check valve is for delivery of liquid, and it is provided with a reducing valve body, and this body cavity part is the major diameter inner chamber, and another part is the minor diameter inner chamber that communicates, and is provided with non-return valve core at body cavity.During use, the internal thread of the minor diameter inner chamber of reducing check valve is connected with goose-neck type water tap, the internal thread of major diameter inner chamber is connected with arm, thereby avoids air to enter water system.But, also have some residual gass in the inner chamber, affect the function of reducing check valve.
The model utility content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of reducing check valve body to be provided.
The utility model is achieved through the following technical solutions:
The reducing check valve body is characterized in that: include a cylindrical shell, the part of the inner chamber of described cylindrical shell is the major diameter inner chamber, the minor diameter inner chamber of another part for communicating with the major diameter inner chamber, and the end of major diameter inner chamber, minor diameter inner chamber is equipped with internal thread; Also be provided with a through hole to be opened/closed on the cylindrical shell as relief opening.
Described relief opening is circumscribed with a sealing cover.
Principle of the present utility model is:
During use, the internal thread of the minor diameter inner chamber of reducing check valve body is connected with goose-neck type water tap, the internal thread of major diameter inner chamber is connected with arm, thereby avoids air to enter water system; Relief opening connects vacuum pump by outlet pipe, and vacuum pump is extracted the residual gas in the inner chamber out.
The utility model has the advantages that:
The utility model is simple in structure, volume is little, easy to install, reduce investment outlay, integrate reducer union and safety check.
Description of drawings
Fig. 1 is the structural representation take the minor diameter inner chamber as the visual angle of the present utility model.
Fig. 2 is the structural representation take the major diameter inner chamber as the visual angle of the present utility model.
Embodiment
