Description

Technical Field

[0001] The utility model relates to a three-way distributing valve for building materials, which belongs to the technical field of distributing valves. Background Art

[0002] Widely used in construction material delivery systems, three-way dispensing valves are ideal for controlling the rapid reversal of material flow. They consist primarily of a valve body, a valve plate, and a drive mechanism. During operation, the drive mechanism causes the valve plate to swing at a specific angle, thereby controlling the flow and dispensing of materials.

[0003] However, in the construction industry, during the long-term use of the three-way distributing valve, construction materials (such as mortar, dry sand) can easily cause wear to the valve body, valve plate and other components, resulting in the three-way distributing valve being unable to be used normally, thereby shortening the service life of the three-way distributing valve. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a three-way material distributing valve for building materials, which is easy to install and maintain and prolongs the service life of the equipment.

[0011] A wear-resistant plate is detachably connected to the inner wall of the valve body.

[0012] Furthermore, the driving mechanism includes a cylinder and a rocker arm, the cylinder is fixed on the side wall of the valve body, one end of the rocker arm is hinged to the piston rod of the cylinder, and the other end of the rocker arm is fixedly connected to one end of the valve shaft.

[0013] Furthermore, one end of the valve shaft is a hexagonal structure, the other end of the rocker arm is provided with a hexagonal hole that matches the hexagonal structure, a threaded hole is provided in the hexagonal structure, and the other end of the rocker arm is fastened to one end of the valve shaft by a screw.

[0024] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0025] like Figures 1 to 6 As shown, this embodiment provides a three-way distributing valve for building materials, which includes a valve body 1, a driving mechanism, a valve shaft 2, a shaft sleeve 3 and a valve plate 4.

[0026] like Figure 1 、 3As shown, the top of the valve body 1 of this embodiment is provided with a feed channel 11, and the bottom of the valve body 1 is provided with a first discharge channel 12 and a second discharge channel 13. The feed channel 11, the first discharge channel 12 and the second discharge channel 13 are interconnected. The building material enters from the feed channel 11, and then the rotation of the control valve plate 4 is controlled to control whether the building material is discharged from the first discharge channel 12 or the second discharge channel 13. Figure 3 The state of the middle valve plate 4 is that the first discharge channel 12 is open, the second discharge channel 13 is closed, and the building material is discharged from the first discharge channel 12.

[0027] like Figure 2 、 3 As shown in Figures 4 and 5, the valve plate 4 of this embodiment is located inside the valve body 1, and the valve plate 4 is connected to the shaft sleeve 3, which is fixed to the outer periphery of the valve shaft 2. A bearing seat 5 is provided on the side wall of the valve body 1, and bearings 6 are provided at both ends of the valve shaft 2, and the bearings 6 are provided in the bearing seat 5. Both bearing seats 5 are fixed to the side wall of the valve body 1 by screws, and the bearings 6 are installed in the bearing seat 5. The valve plate 4 is welded to the side wall of the shaft sleeve 3, and a reinforcing rib 10 is provided between the shaft sleeve 3 and the valve plate 4 to improve the connection strength of the valve plate 4. The shaft sleeve 3 is sleeved on the outer periphery of the valve shaft 2 and then fixed by screws. When the valve plate 4 is severely worn and needs to be replaced, the bearing seat 5 can be disassembled by loosening the screws on the bearing seat 5 and the drive mechanism, and then the valve shaft 2 can be pulled out and the valve plate 4 can be taken out for replacement.

[0028] like Figure 1 、 3 As shown, the driving mechanism of this embodiment is used to drive the valve shaft 2 to rotate, and the valve shaft 2 drives the valve plate 4 to rotate. The valve plate 4 is used to control the connection between the feed channel 11 and the first discharge channel 12 and the connection between the feed channel 11 and the second discharge channel 13. Figure 4 、 5 As shown in Figures 6 and 7, the drive mechanism of this embodiment includes a cylinder 81 and a rocker arm 82. The cylinder 81 is fixed to the side wall of the valve body 1, and one end of the rocker arm 82 is hingedly connected to the piston rod of the cylinder 81. One end of the valve shaft 2 has a hexagonal structure, and the other end of the rocker arm 82 has a hexagonal hole 821 that mates with the hexagonal structure. The hexagonal structure is provided with a threaded hole 21. The other end of the rocker arm 82 is fastened to one end of the valve shaft 2 by a screw. When the piston rod of the cylinder 81 extends, the rocker arm 82 drives the valve plate 4 to rotate toward the first discharge channel 12 until the valve plate 4 completely blocks the first discharge channel 12. At this time, the material passes through the feed channel 11 and is discharged from the second discharge channel 13. When the piston rod of the cylinder 81 retracts, the rocker arm 82 drives the valve plate 4 to rotate toward the second discharge channel 13 until the valve plate 4 completely blocks the second discharge channel 13. At this time, the material passes through the feed channel 11 and is discharged from the first discharge channel 12.

[0029] like Figure 3 、 4 As shown, a wear-resistant plate 7 is detachably attached to the inner wall of the valve body 1 of this embodiment. This plate is secured to the inner wall of the valve body 1 with screws. During normal use, building materials come into contact and rub against the wear-resistant plate 7. Made of manganese plate, the wear-resistant plate 7 is durable and effectively extends the service life of the valve body 1. If the wear-resistant plate 7 becomes damaged from prolonged use, it can be quickly and conveniently replaced by simply loosening the screws.

[0030] like Figure 3 As shown, in this embodiment, a shock-absorbing pad 9 is provided at the end of the valve plate 4. The shock-absorbing pad 9 is made of PU and acts as a shock absorber when the valve plate 4 contacts the inner wall of the valve body 1. At the same time, the shock-absorbing pad 9 is installed at the end of the valve plate 4 to provide a sealing effect, preventing material from leaking from the end of the valve plate 4 during unloading.

[0031] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
