Description

Technical Field

[0001] The utility model relates to the technical field of groove gate valves, in particular to a high-temperature pneumatic trapezoidal groove gate valve. Background Art

[0002] Traditional grooved gate valves are widely used in the fields of water supply and drainage, petroleum, chemical industry, water treatment, etc. to transport fluids and play a role in controlling fluids. They adopt a flat bottom design to prevent debris from accumulating in the groove at the bottom of the valve.

[0003] Traditional grooved gate valves utilize a closed tubular structure, such as the high-pressure grooved gate valve described in utility model patent publication number CN212616400U. However, in some high-temperature fluid transportation applications, such as high-temperature molten steel and steel slag slurry, a guide groove structure with an upper opening is used. Traditional closed grooved gate valves are not structurally compatible with the guide groove structure required for transporting high-temperature fluids, and are also unsuitable for high-temperature fluids and prone to damage.

[0028] The present invention is further described in detail below with reference to the embodiments.

[0029] Specific embodiment 1 of the high-temperature pneumatic trapezoidal groove gate valve provided by the utility model:

[0030] See also Figure 1-2 A high-temperature pneumatic trapezoidal grooved gate valve includes a groove 1 and a gate plate 2 made of high-temperature resistant materials. In this embodiment, both the groove 1 and the gate plate 2 are made of silicate. Silicate is commonly used in fireproof panels and refractory bricks, and as a gate valve structure, it can better adapt to the transportation and control of high-temperature fluids. In other embodiments, the groove 1 and the gate plate 2 can be made of other high-temperature resistant materials instead of silicate.

[0031] In this embodiment, both the groove 1 and the gate plate 2 are cast. The gate plate 2 is shaped like an inverted trapezoid, and the cross-section of the inner channel formed by the groove 1 is also an inverted trapezoid. The gate plate 2 is located above the groove 1, and the shape of the gate plate 2 and the groove 1 are adapted. The inverted trapezoidal cross-section of the gate plate 2 and the groove 1 provides excellent stability and good barrier properties. The contact and separation of the gate plate 2 and the groove 1 can achieve the blocking and control of the high-temperature fluid.

[0032] A frame is mounted above the groove 1, on which is mounted a vertical driver 3 that drives the gate plate 2 up and down. The frame supports the driver 3. In this embodiment, the driver 3 is a linear cylinder. The telescopic end of the driver 3 is connected to the upper side of the gate plate 2. The telescopic end of the driver 3 is extended and retracted to achieve the raising and lowering of the gate plate 2, thereby achieving the contact and separation of the gate plate 2 from the inner side of the groove 1.

[0033] In this embodiment, the frame includes a gantry 7, diagonal braces 8, and reinforcing rods 9; the lower end of the gantry 7 can be fixed on the upper side of the groove 1, or it can be fixed on the hardened ground on both sides of the groove 1. In this embodiment, the gantry 7 is fixed to the ground by bolts. The diagonal braces 8 support both sides of the gantry 7 to prevent the gantry 7 from tilting. The reinforcing rods 9 are connected at the corners of the gantry 7 to ensure the stability of the structure of the gantry 7 itself and to prevent the gantry 7 from deforming. In some embodiments, the gantry 7 and the diagonal braces 8 are both made of channel steel. The frame can ensure the accuracy of the action of the driving member 3. A vertical limit plate 10 is connected to the lower side of the upper part of the gantry 7. The limit plate 10 is set to be U-shaped. The limit plate 10 is located on the downstream side of the gate 2 facing the high-temperature fluid, and can play a certain limiting role on the gate 2.

[0034] A core plate 4 is provided inside the gate plate 2. The upper end of the core plate 4 extends out of the gate plate 2 and is bolted to the telescopic end of the drive member 3. A plurality of first steel bars 5 extending into the gate plate 2 are connected to the outer side of the core plate 4. The first steel bars 5 are Y-shaped steel bars, and the core plate 4 is a stainless steel plate.

[0035] A second steel bar body 6 is provided inside the groove 1; the second steel bar body 6 includes a plurality of transverse steel bars, a plurality of longitudinal steel bars and a plurality of Y-shaped steel bars. The transverse steel bars are U-shaped, and the transverse steel bars are tied and connected to the longitudinal steel bars. The Y-shaped steel bars in the groove 1 are welded to the transverse steel bars.

[0036] The core plate 4 and first reinforcement 5 within the gate plate 2 are pre-fabricated, as are the second reinforcement 6 within the groove 1. These are then placed into molds for the gate plate 2 and groove 1, respectively, and silicate is poured and treated. The gate plate 2 and its internal structure, as well as the groove 1 and its internal structure, resemble reinforced concrete. This structure provides the gate valve with high strength and durability, while the silicate material provides excellent high-temperature resistance.

[0037] Specific embodiment 2 of the high-temperature pneumatic trapezoidal groove gate valve provided by the utility model:

[0038] The difference between this embodiment and embodiment 1 is: Figure 3-4In this embodiment, a scraper 11 is provided. This scraper 11 is located on the upstream side of the gate plate 2, facing the direction of the high-temperature fluid. The scraper 11 is in contact with the gate plate 2, and its ends are connected to the gantry 7. As the gate plate 2 rises and leaves the groove 1, the scraper 11 can scrape off the high-temperature slurry adhering to the surface of the gate plate 2.

[0039] In this embodiment, the scraper plate 11 is V-shaped, with the lowest point of the scraper plate 11 located in the middle of the side surface of the gate plate 2. The V-shaped scraper plate 11 has a certain convergence effect on the scraped high-temperature slurry. During the scraping process, the high-temperature slurry on the lower side of the scraper plate 11 converges and moves downward toward the center along the scraper plate 11. The surface converges at the lowest point in the middle of the scraper plate 11, making it easier to separate from the scraper plate 11 and fall into the groove 1.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
