The membrane type electromagnetic valve of the oxygen generator in the prior art comprises a main body, a valve body, a cover plate, a valve seat and a pilot head, wherein the cover plate covers the top of the valve body, the valve seat is fixed on the cover plate, and the pilot head is fixed on the valve seat. The drawbacks of this structure are: because apron and disk seat are split type structure, the two needs fix with the help of the screw during assembly, still need set up three sealing washer (correspond the guide's gas port respectively moreover between the two (two guide's work mouthful promptly and a guide's air inlet) to prevent that earlier gas guide department from taking place to leak, thereby make the assembly loaded down with trivial details and the processing cost is higher.
Disclosure of Invention
The utility model aims to provide a diaphragm type electromagnetic valve of an oxygenerator, which adopts an integrated valve seat to replace a split type valve seat and a cover plate in the prior art, can effectively reduce the number of accessories, is more convenient to assemble and lower in processing cost, and is more favorable for preventing a pilot gas port from leaking.
The technical purpose of the utility model is realized by the following technical scheme: a diaphragm type electromagnetic valve of an oxygenerator comprises a valve body, a valve cover and a pilot head, wherein the lower end of the valve cover is fixedly connected with the valve body, a valve seat is integrally formed at the upper end of the valve cover, and the pilot head is fixedly connected with the valve seat;
the valve body is internally provided with a valve cavity for accommodating the valve rod assembly, the valve body is provided with an air inlet P and an air outlet R which are respectively communicated with the valve cavity, the valve body is provided with an air outlet A which is correspondingly arranged with the valve cavity, and the valve body is also provided with a pilot valve air inlet channel I which is communicated with the air inlet P;
and a pilot valve air inlet channel II communicated with the pilot valve air inlet channel I and a pilot valve air outlet channel used for communicating the corresponding valve cavity are arranged in the integrated valve seat formed by the valve cover and the valve seat, and the pilot valve air outlet channel is communicated with the pilot valve head.
Further, the integrated valve seat is integrally formed by injection molding.
Further, the valve rod assembly adopts a diaphragm type valve rod.
In conclusion, the utility model has the following beneficial effects:
the utility model provides an oxygen generator diaphragm formula solenoid valve, adopts split type disk seat and apron among the integral type disk seat replacement prior art, can effectively reduce accessory quantity, and not only the assembly is more convenient, the processing cost is lower, more is favorable to stopping moreover that the guide's gas port appears leaking.
