The utility model discloses a diaphragm compressor membrane head structure that publication number CN114215726A discloses, including lower membrane head, upper membrane head, be equipped with intake pipe and blast pipe in the upper membrane head, the body of intake pipe and blast pipe communicates to the sunken face of upper membrane head, and the cavity between the body of intake pipe and blast pipe in the upper membrane head and the diaphragm forms closed air cavity B; when the diaphragm is deformed in a reciprocating manner through hydraulic oil, the closed air cavity B in the upper diaphragm head is pushed to reduce and enlarge. Be equipped with the admission valve in the first intake pipe of last membrane, be equipped with discharge valve in the blast pipe, open and close through discharge valve and admission valve and realize gaseous breathing in, compression, exhaust process, intake pipe and blast pipe are fixed on last membrane head through the second clamp plate respectively. However, for a small displacement diaphragm compressor, the distance between the inlet pipe and the outlet pipe is correspondingly reduced, and the way of fixing the inlet pipe and the outlet pipe by using the second pressure plate is not feasible: scaling down the second platen by an equal amount will result in the strength of the second platen and the fasteners securing the second platen failing to meet the strength requirements.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "connected" are to be understood broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediate medium, or connected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-3, the novel air valve mounting structure of the diaphragm compressor comprises an upper membrane head 100 and a lower membrane head 200, wherein an exhaust valve mounting hole 101 is formed in the center of the upper membrane head 100, an intake valve mounting hole 102 is formed in an eccentric position, internal threads are processed on the upper sections of the exhaust valve mounting hole 101 and the intake valve mounting hole 102, external threads are processed on the upper sections of an exhaust valve pipe 1 and an intake valve pipe 2 correspondingly, and the exhaust valve pipe 1 and the intake valve pipe 2 are connected to the upper membrane head 100 in a threaded manner.
