Abstract

The invention discloses a sand valve and a sand blasting and rust removal system, and relates to the technical field of mechanical design. When an elastic assembly (03) of the sand valve is in a natural state, a blocking piece (02) can make contact with a target sand opening and blocks the target sand opening; and when an adjusting piece (07) rotates a rotary shaft (05) through a connecting rod (06), the rotary shaft (05) can drive a pressure head (04) to compress the elastic assembly (03) to enable the blocking piece (02) to be separated from the target sand opening. According to the sand valve provided by the embodiment of the invention, the telescopic state of the elastic assembly (03) can be controlled through rotation of the rotary shaft (05), the distance between the blocking piece (02) and the target sand opening is controlled, and thus the sand supplying amount of the sand valve can be adjusted; and the sand supplying amount does not need to be adjusted by rotating a manual wheel, the problem that the sand supplying amount is difficult to adjust due to sand blocking can be avoided, the adjusting efficiency of the sand supplying amount of the sand valve provided by the invention is high, using flexibility is high, and operation is easy.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a sand valve and a sandblasting rust removal system. Background technique [0002] At present, the sand valve in the sand blasting and derusting system is a straight-hole sand valve, which is provided with a sand inlet (also called the upper sand supply port) and a sand outlet (also called the lower end sand supply port). The sand material entering through the mouth can fall into the sand outlet and be discharged from the sand valve. The sand valve may also include a manual wheel arranged outside the sand valve, and a blocking member arranged inside the sand valve and connected with the manual wheel, and the blocking member may be used to block the sand outlet. [0003] In the related art, the sand supply amount of the sand valve can be controlled by adjusting the distance between the blocking member and the sand outlet by turning the manual wheel. Wherein, the sand supply amou...
