Description

Technical Field

[0001] The utility model relates to the technical field of spraying machines, in particular to a discharge structure of a fire retardant paint spraying machine. Background Art

[0002] Fire retardant spraying is a key technology in modern building fire protection. It involves using specialized machinery to evenly spray fire retardant coatings onto building structures. These coatings typically have high viscosity and a high solids content, so the spraying equipment needs to be able to efficiently, evenly, and continuously deliver these viscous coatings.

[0003] However, traditional equipment is prone to nozzle or delivery pipe blockage when processing high-viscosity coatings. Especially in continuous operations, blockage will seriously affect operating efficiency and coating quality. Utility Model Content

[0004] In response to the above-mentioned problems, the present invention provides a discharge structure for a fire-retardant coating sprayer, which effectively solves the problem that nozzles or delivery pipes are easily clogged when traditional equipment processes high-viscosity coatings.

[0005] The utility model adopts the following technical scheme: a discharge structure of a fire retardant paint sprayer, comprising a cylinder body, a plunger being slidably connected to the cylinder body, a sealing ring being provided on the plunger, a cylinder cover being provided on the top of the cylinder body, a plunger rod being provided on the top of the plunger, the plunger rod passing through the cylinder cover and being slidably connected to the cylinder cover, a suction valve body being provided at the bottom of the cylinder body, an outlet valve body being connected to one side of the cylinder body through a pipeline, a sphere being provided at the suction valve body and the outlet valve body, a limiting ring being provided at the top of the inner side wall of the suction valve body and the outlet valve body, respectively located above the sphere, a suction port being provided at the bottom of the suction valve body, and a discharge port being provided at the top of the outlet valve body.

[0006] Furthermore, the cylinder body is connected to the bottom of the outlet valve body through a pipeline.

[0007] Furthermore, the cross-sectional diameters of the holes at the bottom of the suction valve body and the outlet valve body are smaller than the cross-sectional diameter of the sphere.

[0008] Furthermore, the sphere is made of tungsten steel.

[0009] Furthermore, the plunger rod is driven by a hydraulic cylinder to suck the spray material from the suction port and spray it out from the spray gun connected to the discharge port.

[0010] The advantages of the present invention are: the sliding connection of the plunger and the sealing ring in the cylinder body ensures the smooth transportation of the spray material in the cylinder body without leakage. Driven by the hydraulic cylinder, the plunger rod can effectively maintain efficient fluidity when sucking in and discharging the spray material, avoiding the blockage of the material during the transportation process. A ball is provided inside the suction valve body and the outlet valve body, which can accurately control the opening and closing of the suction valve body and the outlet valve body, ensuring that the ball moves only in the appropriate position, thereby preventing the backflow and leakage of the material. The diameter of the ball is larger than the diameter of the bottom hole of the valve, which ensures that the material can only pass through under pressure, effectively preventing the blockage of the valve. The ball made of tungsten steel provides a high degree of strength and wear resistance. Especially in the harsh environment of fire-proof spraying, the high temperature resistance and corrosion resistance of tungsten steel ensure the long-term stability and reliable operation of the valve mechanism.

[0014] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0015] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0016] See Figure 1-2As shown, a discharge structure of a fire retardant paint sprayer includes a cylinder body 1, a plunger 2 is slidably connected in the cylinder body 1, a sealing ring 3 is provided on the plunger 2, a cylinder cover 4 is provided on the top of the cylinder body 1, a plunger rod 5 is provided on the top of the plunger 2, the plunger rod 5 passes through the cylinder cover 4 and is slidably connected to the cylinder cover 4, a suction valve body 6 is provided at the bottom of the cylinder body 1, and a discharge valve body 7 is connected to one side of the cylinder body 1 through a pipeline, a ball 8 is provided in the suction valve body 6 and the discharge valve body 7, and a limit ring 9 is provided on the top of the inner side wall of the suction valve body 6 and the discharge valve body 7 respectively above the ball 8, a suction port 10 is provided at the bottom of the suction valve body 6, and a discharge port 11 is provided at the top of the discharge valve body 7.

[0017] The cylinder body 1 is connected to the bottom of the outlet valve body 7 through a pipeline, so that the transmission of the spraying material is smoother.

[0018] The cross-sectional diameter of the holes at the bottom of the suction valve body 6 and the discharge valve body 7 is smaller than the cross-sectional diameter of the sphere 8, which ensures that the sphere 8 will not fall, ensures the unidirectional flow of the material, and effectively prevents the backflow and leakage of the spray material.

[0019] The sphere 8 is made of tungsten steel, which improves the wear resistance and corrosion resistance of the sphere. In particular, when processing corrosive fireproof materials, the tungsten steel sphere can maintain its shape and function for a long time.

[0020] The plunger rod 5 is driven by a hydraulic cylinder to suck the spray material from the suction port 10 and spray it out from the spray gun connected to the discharge port 11.

[0021] Working principle: When the hydraulic cylinder drives the plunger rod 5 upward, suction is generated in the cylinder body 1, sucking the ball 8 in the suction valve body 6 upward, and at the same time sucking the spray material from the suction port 10. The spray material passes through the cylinder body 1 and is connected to the outlet valve body 7 through a pipe. The ball 8 will move downward to block the bottom of the outlet valve body 7. At this time, the cylinder body 1 is full of spray material. Then when the hydraulic cylinder drives the plunger rod 5 downward, the ball 8 in the suction valve body 6 will move downward to block the bottom of the suction valve body 6, and the ball 8 in the outlet valve body 7 will move upward. The spray material will pass through the pipe through the outlet valve body 7 and be sprayed out through the spray gun connected to the outlet 11.

[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
