Problems solved by technology

The prior art has the following problems: 1. The inflation pressure cannot be adjusted, and cannot adapt to the tire pressure requirements of different working conditions
2. It is inconvenient to use and operate. It is necessary to use a special tool to open the valve core 6 of the tire before use, and to close the valve core 6 after inflation.
3. The sealing is not good. If the valve core 6 is damaged, the minimum air pressure necessary for the tire cannot be guaranteed, resulting in the tire roller not working normally.
The above problems have different degrees of adverse effects on the normal working efficiency and performance of the tire roller

Abstract

The present invention relates to a tyre inflation unit of tyre street roller. It includes valve body and valve stem and piston which are mounted in the interior of valve body, the piston is positioned in the upper end of valve stem. The described piston can be used for dividing upper portion of internal cavity of valve body into pressure accumulating cavity and elastic force cavity. Two ends of said valve body are equipped with an upper end cover and a lower end cover, and said valve body has a valve body air guide channel, one end of said valve body air guide channel is communicated with air inlet set on the valve body, and its another end is communicated with pressure accumulating cavity by means of end cover air guide channel set on the upper end cover, the lower end of the valve stem is extended to air outlet set on the lower end cover.

Description

technical field [0001] The invention mainly relates to the field of road construction machinery, in particular to a tire inflation device of a tire road roller. Background technique [0002] Such as figure 1 As shown, the tire inflation device of the existing tire roller includes a valve body 1, a fixed nut 7 installed on the upper end of the valve body 1, an adjusting screw 9 installed in the fixed nut 7, and a piston installed in the valve body 1. 3 and stem 2. The prior art has the following problems: 1. The inflation pressure cannot be adjusted, and cannot meet the requirements of tire pressure in different working conditions. 2. It is inconvenient to use and operate. It is necessary to use a special tool to open the valve core 6 of the tire before use. After inflation, the valve core 6 must be closed. 3. The sealing is not good. If the valve core 6 is damaged, the tire cannot be guaranteed. Minimum air pressure, causing the tire roller to not work properly. The abov...
