Description

Technical Field

[0001] This utility model belongs to the field of premixed mortar mixing design technology, specifically relating to a leak-proof air pressure three-way valve device for premixed mortar powder diversion. Background Technology

[0002] Premixed mortar has been developed and applied as a new type of environmentally friendly building material. Premixed mortar is a fine-aggregate concrete used in various mortar mixtures in construction projects. It consists of a certain proportion of cementitious materials, fine aggregates, and additives, and has many advantages such as less on-site pollution, good operability, and high project progress efficiency. However, existing premixed mortars suffer from problems such as easy cracking and poor impermeability. Some premixed mortars also contain blast furnace slag, but the porosity and metal ions of blast furnace slag affect the performance of the premixed mortar. In the powder diversion process of premixed mortar, existing three-way valves for powder diversion are used. Three-way diverter valves are devices used in material conveying systems to control the rapid reversal of material flow. They are widely used in industries such as building materials, metallurgy, mining, light industry, and grain for conveying solid particles and powders. Existing three-way valves mainly provide material diversion, and there is a small gap between the valve plate and the side. When conveying premixed mortar powder, it needs to work under positive and negative pressure conditions. Under air pressure, a large amount of powder will flow out from the small gap, causing serious material leakage problems.

[0003] Therefore, there is an urgent need for a leak-proof three-way valve device to solve the problem of material leakage caused by air leakage during the diversion and transportation of premixed mortar powder under positive and negative pressure conditions. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a leak-proof air pressure three-way valve device for the diversion of premixed mortar powder.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a leak-proof pneumatic three-way valve device for premixed mortar powder diversion, comprising a valve body, a first valve plate, a second valve plate, a valve plate driving mechanism, and a sealing and limiting mechanism. The valve body has an inlet at the upper end and a left outlet and a right outlet at the lower end. A valve plate shaft is provided in the middle of the valve body. The first valve plate and the second valve plate are disposed in the valve body and fixedly connected to the valve plate shaft. The first valve plate and the second valve plate rotate synchronously with the rotation of the valve plate shaft. The valve plate driving mechanism is connected to the valve plate shaft and drives the valve plate shaft to rotate. The sealing and limiting mechanism includes a limiting frame and a sealing strip. The limiting frame is disposed on the inner wall of the valve body and is disposed between the inlet and the outlet, abutting against the first valve plate and the second valve plate, for limiting the rotation angle of the first valve plate or the second valve plate. The sealing strip is disposed on the limiting frame.

[0006] Furthermore, a trapezoidal plate is provided inside the valve body, which is located below the valve plate shaft to separate the left discharge port and the right discharge port.

[0007] Furthermore, the left and right discharge ports are arranged symmetrically.

[0008] Furthermore, the first valve plate and the second valve plate are two flat plates.

[0009] Furthermore, the valve plate drive mechanism includes an arc-shaped rotating arm and an electric push rod. The arc-shaped rotating arm is disposed outside the valve body. One end of the arc-shaped rotating arm is fixedly connected to the valve plate shaft, and the other end is connected to the electric push rod. The electric push rod drives the arc-shaped rotating arm to rotate, thereby driving the valve plate shaft to rotate.

[0010] Furthermore, the valve plate drive mechanism also includes a mounting base, which is fixed to the outer wall of the valve body, and the electric push rod is fixedly mounted on the mounting base.

[0011] Furthermore, the side of the limiting frame that abuts against the first valve plate and the second valve plate has a groove, and the sealing strip is embedded in the groove.

[0012] Furthermore, the limiting frame includes a first frame and a second frame, which are arranged between the feed inlet and the valve plate shaft.

[0013] Furthermore, the first frame and the second frame are arranged at an acute angle.

[0014] Furthermore, the limiting frame includes a third frame and a fourth frame, wherein the third frame is arranged between the valve plate shaft and the left discharge port, and the fourth frame is arranged between the valve plate shaft and the right discharge port.

[0015] The leak-proof pneumatic three-way valve device for premixed mortar powder diversion described in this utility model effectively avoids material leakage caused by incomplete closure of the valve body. It also avoids material leakage through small gaps under positive and negative pressure, as well as material accumulation or uneven feeding in the valve when the first and second valve plates are at large inclination angles. This device has a simple structure and can achieve reversing operation without the need to install two sets of automatic control valves, thus reducing costs. It can be widely used in the process of premixed mortar powder diversion, especially suitable for three-way material diversion in powder conveying under pneumatic conditions.

[0018] The present invention will be further described below through specific embodiments.

[0019] like Figures 1 to 2 As shown, the leak-proof pneumatic three-way valve device for premixed mortar powder diversion described in this utility model includes a valve body 1, a first valve plate 2, a second valve plate 3, a valve plate driving mechanism 4, and a sealing and limiting mechanism 5.

[0020] The valve body 1 has an inlet 11 at the upper end, a left outlet 12 and a right outlet 13 at the lower end, and a valve plate shaft 14 in the middle of the valve body 1. A trapezoidal plate 15 is provided below the valve plate shaft 14 to separate the left outlet 12 and the right outlet 13. The left outlet 12 and the right outlet 13 are arranged symmetrically.

[0021] The first valve plate 2 and the second valve plate 3 are disposed inside the valve body 1. The first valve plate 2 and the second valve plate 3 are two flat plates. The first valve plate 2 and the second valve plate 3 form a certain angle and are fixedly connected to the valve plate shaft 14. The first valve plate 2 and the second valve plate 3 rotate synchronously with the rotation of the valve plate shaft 14.

[0022] The valve plate drive mechanism 4 includes an arc-shaped rotating arm 41, an electric push rod 42, and a mounting base 43. The arc-shaped rotating arm 41 is disposed outside the valve body 1. One end of the arc-shaped rotating arm 41 is fixedly connected to the valve plate shaft 14, and the other end is connected to the electric push rod 42. The electric push rod 42 drives the arc-shaped rotating arm 12 to rotate, thereby driving the valve plate shaft 14 to rotate. The mounting base 43 is fixed on the outer wall of the valve body 1, and the electric push rod 42 is fixedly installed on the mounting base.

[0023] The sealing and limiting mechanism 5 includes a limiting frame 51 and a sealing strip 52. The limiting frame 51 is disposed on the inner wall of the valve body 1. The limiting frame 51 is positioned between the inlet 11 and the outlet, abutting against the first valve plate 2 and the second valve plate 3, and is used to limit the rotation angle of the first valve plate 2 or the second valve plate 3. The limiting frame 51 has a groove on the side abutting against the first valve plate 2 and the second valve plate 3, and the sealing strip 52 is embedded in the groove. The sealing strip is made of silicone, sponge, rubber, etc. Made of elastic material, the limiting frame 51 includes a first frame 511, a second frame 512, a third frame 513, and a fourth frame 514. The first frame 511 and the second frame 512 are arranged between the feed inlet 11 and the valve plate shaft 14. The first frame 511 and the second frame 512 are arranged at an acute angle, roughly in a V shape. The third frame 513 is arranged between the valve plate shaft 14 and the left discharge port 12, and the fourth frame 514 is arranged between the valve plate shaft 14 and the right discharge port 13.

[0024] Reference Figure 1 , Figure 2 As shown, the working process of the above-mentioned leak-proof pneumatic three-way valve device applied to the diversion of premixed mortar powder is as follows:

[0025] The front-end powder enters the valve body 1 through the feed port 11. The powder can be conveyed through the left discharge port 12 or the right discharge port 13, which allows the front-end powder to be conveyed to different pipelines at the lower end through the valve control. The electric push rod 42 controls the arc-shaped rotating arm 12 to rotate, which in turn drives the valve plate shaft 14 to rotate. When the left discharge port 12 is selected to feed, the first valve plate 2 abuts against the third frame 513 and the second valve plate 3 abuts against the second frame 512. At this time, the feed port 11 is connected to the left discharge port 12. When the right discharge port 13 is selected to feed, the first valve plate 2 abuts against the first frame 511 and the second valve plate 3 abuts against the fourth frame 514. At this time, the feed port 11 is connected to the right discharge port 13. When the first valve plate 2 and the second valve plate 3 rotate to the limit frame 51, they are pressed against the sealing strip 52 to achieve sealing.

[0026] The leak-proof pneumatic three-way valve device for premixed mortar powder diversion described above effectively avoids the leakage problem caused by the valve body 1 not closing tightly. At the same time, it avoids the problem of powder leakage through small gaps under positive and negative pressure, as well as the problem of powder accumulation or uneven feeding in the valve when the first valve plate 2 and the second valve plate 3 are at a large tilt angle. The device has a simple structure and can realize the reversing operation without the need to install two sets of automatic control valves, which reduces the cost. It can be widely used in the process of premixed mortar powder diversion, especially suitable for the three-way material diversion process in powder conveying under pneumatic conditions.

[0027] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
