The invention relates to a mortar spraying gun, which is characterized in that a flow control valve is arranged in a compressed air pipe, and the flow control valve has three states of high-flow complete opening and low-flow micro opening and closing, so that after the spraying work on a working surface is finished, the flow control valve can be opened and closed; high-pressure gas in the air pipe is converted into small flow through the flow control valve, then the mortar pumping mechanism is closed through cooperation with the pressure switch (flow switch) to suspend mortar conveying, meanwhile, the high-pressure gas with the small flow in the air pipe is used for blowing away mortar remaining in the inner cavity of the nozzle, condensation and blockage are avoided, and the service life of the nozzle is prolonged. And after the high-pressure gas in the air pipe is transferred to the other working face, the high-pressure gas in the air pipe is converted into large flow through the flow control valve, and the mortar pumping mechanism is started to start mortar conveying and continuous spraying work in cooperation with the pressure switch (flow switch), so that the working continuity is kept, the use is convenient, and the working efficiency is greatly improved.
本发明涉及一种砂浆喷涂枪，通过在所述压缩空气管中设置有流量控制阀门，所述流量控制阀门具有大流量的完全开启、小流量的微开启及关闭三种状态，当完成在一个作业面的喷涂工作后，先通过所述流量控制阀门将空气管中高压气体转为小流量，再配合以压力开关（流量开关）关闭砂浆泵送机构暂停砂浆的输送，同时利用空气管中小流量高压气体将残留在喷嘴内腔中的砂浆吹净，避免了出现凝结堵塞，转移至另一个工作面后，再通过所述流量控制阀门将空气管中高压气体转为大流量，再配合以压力开关（流量开关）启动砂浆泵送机构开始砂浆的输送，继续喷涂工作，保持了工作的连续性，方便了使用，并大大地提高了工作效率。
