Abstract

The invention discloses a flow adjustable fluid injection device, and belongs to the technical field of environmental protection. The flow adjustable fluid injection device comprises a sleeve, a rotary drive mechanism, a rotating spindle, a spray head and a piston column; the rotating spindle is arranged inside the sleeve, the spray head is connected with the head end of the sleeve, and the rotarydrive mechanism is arranged at the tail portion of the sleeve and connected with the tail portion of the rotating spindle; the head end of the rotating spindle is provided with a stroke screw rail, athreaded hole is formed in the tail portion of the piston column, and the stroke screw rail is arranged in the threaded hole of the piston column in a penetrating mode and is connected with the piston column in a threaded mode; and the piston column is slidably connected with the sleeve, side wall water inlets are formed in the side wall of the sleeve, spindle water inlets are formed in the middle part of the rotating spindle, spindle water outlets are formed in the head end of the side wall of the rotating spindle, and the spindle water inlets communicate with the spindle water outlets through a spindle flow channel arranged in the spindle. According to the flow adjustable fluid injection device, the rotation of a motor is converted into a linear movement of the piston column by the stroke screw rail, and the accuracy of the flow regulation is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a fluid injection device with adjustable flow rate. Background technique [0002] Existing fluid injection devices generally do not have a flow adjustment function. For example, a fire sprinkler is only used as an outlet port of a fluid. It has not changed, so if the flow rate is low, the velocity of the fluid at the nozzle is low, which is not conducive to spraying the fluid to the target position. If the fluid needs to be sprayed to a longer distance, the flow rate needs to be increased, which causes waste. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a fluid injection device with adjustable flow rate, so as to solve the problems in the prior art that the fluid flow rate and the velocity of the fluid at the nozzle are difficult to control. [0004] The purpose of...
