Air hose joint device for breathe

Abstract

The invention discloses an air hose joint device for breathe, which relates to a connecting piece. The air hose joint device for breathe mainly comprises a joint shell, a valve butt joint and an air valve, wherein the air valve is connected with the joint shell through a hose; a flexible protective cover is arranged at the joint of the hose, the air valve and the joint shell; and the valve butt joint is connected with an air supply device, and one end of the air valve is connected with an air receiving device. When in use, the valve butt joint is clamped into the joint shell, the hose is sheathed on a hose joint at one end of the joint shell, the hose is connected to the hose joint of the air valve, and a communicating inner cavity is formed in the hose joint device for the air to pass through the middle thereof. The air hose joint device for breathe has the advantages of reasonable and reliable design, good airtightness, strong flexure resistance and convenient butting joint and demounting between the valve butt joint and the joint shell. Even if the valve butt joint is demounted, a centering card in the valve butt joint can realize sealing and self-locking to keep good airtightness. Therefore, extraneous air does not pollute the air in a valve body channel, and the sanitation and the safety of the air receiving device can be protected well.

Description

Technical field: [0001] The invention relates to a connecting piece, in particular to a hose joint device. Background technique: [0002] At present, hose connectors are widely used in civil and industrial use to transport liquids and gases. The hose connectors sold on the market have always been prone to leakage, and the sealing part of the hose is easily damaged after repeated use, especially in some special applications. The requirements for the hose joint device are more stringent. With the continuous development of science and technology, a number of hose connectors with technological content have appeared. [0003] Chinese patent 200520039193.8 hose joint device, the joint of the hose adopts the barb structure of the clamp. When installing, you only need to insert the hose directly into the installation head part of the hose joint. When disassembling, you only need to insert the installation head part Press and hold the clip of the installation head inward, and the h...

Problems solved by technology

However, this device has a disadvantage that after the hose is sleeved at the inlet end, because it is transporting gas, it is easy to leak air from the sleeve due to the pressure of the gas.

[0005] However, in some special industries, the sealing and safety and sanitation requirements for hose joints are particularly strict. At present, there is no suitable product in China that can meet the needs.
