Embodiment Construction

[0020] Such as Figure 1-3 As shown, the air-water joint assembly includes an outer joint 1 and a pipe end joint 2 connected to each other. An outer hose 3 and an inner hose 4 passing through the outer hose 3 are connected to the pipe end joint 2. The inner soft The pipe 4 has a water flow channel 5, an air flow channel 6 is formed between the outer hose 3 and the inner hose 4, the pipe end joint 2 has a water passage 7 and an air passage 8 isolated from each other, and the water flow channel 5 is connected to the water passage The channel 7 is connected, and the air flow channel 6 is connected with the air passage 8. The outer joint 1 has a mutually isolated water inlet / outlet channel 9 and an air inlet / outlet channel 10. The outer joint 1 and the pipe end joint 2 are fixed by a positioning structure 11 Connected, and the water passage 7 communicates with the water inlet / outlet passage 9, and the air passage 8 communicates with the air inlet / outlet passage 10.

Abstract

The invention belongs to the technical field of connecting hoses, relates to hose joints, in particular to a gas-water joint assembly and solves the technical problems such as unreasonable design of the prior art. The assembly comprises an outer connecting joint and a pipe end joint; the pipe end joint is connected with an outer hose and an inner hose arranged in the outer hose in a penetrating mode; the inner hose is provided with a water flow channel; a gas flow channel is formed between the outer hose and the inner hose; the pipe end joint is provided with a water passing channel and a gas passing channel, which are mutually separated; the water flow channel is communicated with the water passing channel; the gas flow channel is communicated with the gas passing channel; the outer connecting joint is provided with a water inlet/outlet channel and a gas inlet/outlet channel, which are mutually separated; the outer connecting joint and the pipe end joint are fixedly connected by a positioning structure. The gas-water joint assembly has the advantages that 1, the design is reasonable, the structure is simple and water flows and gas flows can be stably outputted; 2, the structural strength is high, the airtightness is good and the gas-water joint assembly is suitable for different weathers and environments; 3, the cost and maintenance cost are low, the assembly and disassembly are convenient and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of connecting hoses and relates to hose joints, in particular to an air-water joint assembly. Background technique [0002] Hose connectors are used to connect hoses to facilitate the formation of delivery lines. In the prior art, hose joints generally can only transport a single fluid medium to the equipment, because the water and gas transported at the same time cannot satisfy the synchronous work at a specific temperature and pressure. For this reason, people have carried out long-term exploration, put forward various solutions. [0003] For example, Chinese patent literature discloses a water-air integrated rotary joint [application number: 201120256876.4], including: housing, plug, pneumatic rod, hollow shaft, guide pad, pneumatic nozzle, bearing, sealing ring, circlip, The housing is an integral structure; the hollow shaft embedded bearing is located in the housing, and one end protrudes out of the h...
