Embodiment Construction

[0020] Examples of integrated valves are Figure 1~5 Shown: including the valve body 1, the valve body is provided with a gas cylinder interface and an air inlet channel and an air outlet channel 24 connected with the gas cylinder interface. Inflatable joint 5, pressure gauge 15 and blocking cap 16, inflating joint 5 has filter screen, can realize the filtration to gas impurity when inflating, and blocking cap 16 can realize the release of residual pressure in the bottle or as a spare interface. The inlet end of the air outlet channel and the outlet end of the inflatable channel share a section of gas path. The inlet end of the air outlet channel is provided with a filter 14, and the outlet end of the air outlet channel is provided with an air outlet joint 17 and a safety valve 18. The safety valve can ensure that the The pressure is not higher than the set value, such as 0.9Mpa, to ensure the safety of the back-end devices. A spool 12 is installed in the valve body to guide ...

Abstract

The invention relates to an integrated valve. The integrated valve comprises a valve body, wherein the valve body is provided with an air outlet channel; a valve core is movably assembled in the valve body along a forward and backward direction under guidance; the valve body is provided with a driving mechanism which is in transmission connection with the valve core, and is used for driving the valve core to move forwards in order to plug the air outlet channel by the valve core and drive the valve core to move backwards in order to conduct the air outlet channel. When the integrated valve is not needed for exhausting, the driving mechanism is used for driving the valve core to plug the air outlet channel, and the air outlet channel is in a cutoff state; when the integrated valve is needed for exhausting, the driving mechanism is used for driving the valve core to move backwards to conduct the air outlet channel, and gas can be exhausted through the air outlet channel; a cutoff function is realized through active movement of the valve core, function integration of the valve core is realized, and the product is compact in structure; moreover, the conduction and plugging of the air outlet channel are controlled through the driving mechanism without being influenced by the air outlet pressure, so that gas in a gas cylinder can be exhausted fully.

Description

technical field [0001] The invention relates to an integrated valve. Background technique [0002] In actual production and life, integrated valves for oxygen delivery are widely used in civil fields such as welding, cutting, chemical industry, medicine, sanitation, and electronics industry. An existing integrated valve such as "an oxygen valve" disclosed in Chinese patent CN102011879A, the oxygen valve includes a valve body, the valve body is provided with an inlet passage, an outlet passage and a gas cylinder interface, and an inlet passage is provided in the inlet passage. One-way valve, the air outlet channel is provided with an air outlet one-way valve, the air outlet one-way valve includes a spool that guides and moves and is assembled in the valve body, the spool moves forward to block the air outlet channel, and the spool moves backward to let the air out The passage makes the outlet passage conduct, and a spring is provided between the valve core and the valve body...
