Problems solved by technology

However, because the pressure value is difficult to set, it often causes excessive or insufficient internal pressure of the tire, and the internal gas pressure of the tire must be repeatedly released or inflated, causing inconvenience when inflating or driving danger.
[0003] In addition, in the tire pressure detector disclosed in Taiwan Patent No. 578706, the tire pressure detector is directly installed inside the tire. Although it can facilitate the detection of the internal pressure of the tire pressure, it often causes disassembly Inconvenience to install
In order to further make the tire pressure detector easier to install and use, the tire pressure detector is gradually changed to be installed directly on the tire air nozzle outside the tire, but it often causes troubles for tire inflation, and it is difficult to correctly target The internal pressure of the tire is set to provide the correct and appropriate tire pressure

Embodiment Construction

[0040] The accompanying drawings and preferred specific embodiments will be described in detail below, so as to further understand the structure, features and purpose of the present invention.

[0041] Please refer to FIG. 1 , which is a schematic cross-sectional view of an embodiment of the present invention. As shown in the figure, the two-way check valve 1 of the present invention includes a hollow sleeve 10, a connecting sleeve 20, a valve push rod 30, a first valve body 40, a second valve body 50, a first pressure The adjustment assembly 60 , a second pressure adjustment assembly 70 and an air inlet joint 80 . In terms of the combined structure, both ends of the hollow sleeve 10 are respectively screwed to the air nozzle push rod 30 and the air inlet joint 80 , and the connecting sleeve 20 is sheathed on the air nozzle push rod 30 . Moreover, the hollow sleeve 10 has a first sleeve portion 12 and a second sleeve portion 14, and a first accommodating chamber 122 and a fir...

Abstract

The invention relates to a bidirectional check valve, which comprises: a hollow muffle, a connecting muffle, a valve top rod, the first valve, the second valve, the first pressure adjuster, the second pressure adjuster and a gas inlet connector, wherein two ends of hollow muffle are connected to the valve top rod and gas inlet connector; the valve top rod is sheathed with connecting muffle; the hollow muffle has the first and second muffles, to independently contain the first container and the second container; the first container contains the second valve; the second valve has one containing groove, to contain the first valve and the first pressure adjuster; and the second container can contain the pressure adjuster.

Description

technical field [0001] The invention relates to a two-way check valve, in particular to a check valve capable of generating a two-way check when high-pressure gas or fluid passes through. Background technique [0002] Currently, the tire inflators or tire pressure sensors used in the market are all installed on the tire valves on the tires to detect the pressure value inside the tires. And the tire inflator of prior art mainly comprises an inflator nozzle, a pressure gauge and an intake controller, and is connected with an air compressor, makes the user can by controlling the intake controller, the air compressor produces The high-pressure air is input into the tire through the inflation nozzle, and the pressure inside the tire is measured at the same inlet through the pressure gauge. However, because the pressure value is difficult to set, the internal pressure of the tire is often too large or insufficient, and the internal gas pressure of the tire must be released or inf...
