Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, a multi-functional vacuum regulator includes: a lower valve base 102, an upper valve base 101, a valve core 3, a valve body 6 and a rubber sheet 13; one end of the valve core 3 penetrates through and is fixed at the center of the lower valve base 102 through a bolt, the other end of the valve core 3 is arranged at the center of the upper valve base 101, the rubber sheet 13 is arranged between the lower valve base 102 and the upper valve base 101, and the valve body 6 is connected with the upper valve base 101 in a sealing manner; go up disk seat 101 including lid seat 14, base 15, seat circle 7, spring bracket 8, spring 9, pipe nut 10, clamping ring 11 and fixed pin 12, seat circle 7 passes through pipe nut 10 is fixed to be installed in base 15, spring bracket 8 is fixed on the seat circle 7, clamping ring 11 is fixed on the lid seat 14, spring 9 fixes between clamping ring 11 and the seat circle 7, fixed pin 12 passes go up disk seat 101 and lower valve base 102.
