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.
Referring to the attached drawings, the portable mechanical pressure regulating valve comprises a pressure regulating nut 1, a valve core 2 and a valve sleeve 3, wherein a power hole 14 for covering the top of the valve core 2 is formed in the pressure regulating nut 1, a threaded hole 15 communicated with the power hole 14 is formed in the side wall of the pressure regulating nut 1, a power wall 12 is cut at the top of the valve core 2, a screw 4 penetrates through the threaded hole 15 to abut against the power wall 12, and the pressure regulating nut 1 can drive the valve core 2 to rotate; the valve core 2 is provided with a positioning pin 5, a rubber ring is sleeved on the positioning pin, and an air outlet hole 7 is also formed in the valve core 2, and an air outlet notch 8 with gradually reduced depth is formed in the side wall of the valve core 2 along the circumferential direction of the valve core 2 through the air outlet hole 7; the valve sleeve 3 is provided with an air flue outlet 6, and after the valve core 2 is inserted into the valve sleeve 3, the height of the air outlet notch 8 is consistent with that of the air flue outlet 6.
The outer diameter of the valve core 2 of the utility model is equal to the inner diameter of the valve sleeve 3, the principle is that the pressure regulating nut 1 is rotated manually, the pressure regulating nut 1 drives the valve core 2 to rotate, the overlapping area of the air outlet notch 8 and the air outlet 7 on the valve core 2 and the air passage outlet 6 on the valve sleeve 3 is changed, the area can rotate along with the pressure regulating nut 1 in different directions, and the area is increased or decreased from small to large, the larger the overlapping area is, the more the gas discharged from the valve core 2 is, the smaller the air pressure in the valve core 2 is, otherwise, the larger the air pressure is; screw 4 is hexagonal screw 4, can advance screw hole 15 by the hexagonal spanner screw in and until support power wall 12, and when rotatory pressure regulating nut 1 again, hexagonal screw 4 can act on power wall 12 and drive case 2 and rotate, and locating pin 5 can make pressure regulating nut 1 drive case 2 can only at the semicircle internal rotation, and it can be more convenient to use.
The valve core 2 is provided with a first sealing ring 10, a second sealing ring 32 and a third sealing ring 33, the first sealing ring 10 and the second sealing ring 32 are arranged between the positioning pin 5 and the air outlet notch 8, and the third sealing ring 33 is arranged below the air outlet notch 8.
