Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sintering production equipment in the metallurgical industry, and in particular relates to a sliding groove type double-layer valve device. Background Technology
[0002] During sintering production, the double-layer valve under the main flue plays a crucial role. If the sealing effect is not good, it will cause serious air leakage in the sintering machine system, increase system consumption, reduce production capacity, wear and tear on equipment, and increase the labor intensity of workers.
[0003] Conventional double-layer valves have certain limitations due to the special environment on site.
[0004] Because of the constant influx of debris on-site, the cone-type double-layer valve often gets stuck, causing air and material leaks. It also wears down the cone, resulting in an uneven surface that severely affects the sealing effect and shortens its service life.
[0005] In flap-type double-layer valves, the valve plate and valve seat are generally rigidly sealed. If the contact surface is wide, it is easy for debris to get stuck, and if the contact surface is narrow, the service life will be short.
[0006] In conventional double-layer gate valves, whether the valve plate is a single plate or a plate seat type, the contact between the valve plate and the base is a planar contact. The biggest problem with this is material jamming, making it impossible to guarantee a tight seal every time. Air and material leaks occur frequently. Summary of the Invention
[0007] The purpose of this invention is to provide a sliding gate double-layer valve device with a simple structure, good sealing performance, and high reliability.
[0008] The objective of this utility model is achieved through the following technical solution:
[0009] This utility model discloses a sliding groove type double-layer valve device, characterized by comprising an upper sealing seat and a lower sealing seat, a drive mechanism fixed on the upper and lower sealing seats, a seat sealing strip disposed at the interface of the upper and lower sealing seats, a slide plate disposed on the lower sealing seat, and N end sealing strips disposed at the ends of the upper and lower sealing seats.
[0010] The insert plate has beveled surfaces on both sides and at the front end.
[0011] The lower sealing seat has sliding grooves at both ends. The contact surfaces on both sides of the sliding groove are inclined surfaces with the same slope as the inclined surfaces on both sides of the insert plate. The front contact surface of the sliding groove is also inclined.
[0012] The insert plate is slidably connected to the slide groove.
[0013] The front end of the insert plate is a vertical plane.
[0014] The front contact surface of the lower sealing seat is a vertical plane.
[0015] The end sealing strip is pressed onto the insert plate by an end sealing clamping mechanism.
[0016] The N end sealing strips mentioned above, where N is at least 1.
[0017] Advantages of this utility model:
[0018] The sliding groove type double-layer valve device of this utility model has the sliding plate and the lower sealing seat with sliding groove arranged on the slope, which eliminates the possibility of material accumulation and solves the common material jamming phenomenon of all double-layer valves.
[0019] The sliding groove type double-layer valve device of this utility model has a sliding plate located between the upper sealing seat and the lower sealing seat with a sliding groove, which forms a rigid seal by being in close contact with the lower sealing seat with a sliding groove. Since the sliding plate needs to be machined with a bevel, the thickness of the sliding plate must be guaranteed, which also increases the service life.
[0020] The sliding groove type double-layer valve device of this utility model has a sliding groove type plate between the upper sealing seat and the lower sealing seat with a sliding groove, which is in close contact with the sealing strip of the seat body to form a second flexible seal.
[0021] The sliding groove type double-layer valve device of this utility model has end sealing strips installed at the ends of the upper sealing seat and the lower sealing seat with sliding groove. One or more sealing strips can be set, and the sealing effect is better when multiple strips are set.
[0022] The sliding groove type double-layer valve device of this utility model has a small maintenance workload and is more convenient for maintenance and repair. Attached Figure Description
[0023] Figure 1 This is a schematic diagram of the structure of this utility model.
[0024] Figure 2 This utility model Figure 1 Side view. Detailed Implementation
[0025] The specific embodiments of this utility model are further described below with reference to the accompanying drawings.

[0027] The insert plate 4 has beveled surfaces on both sides and at the front end.
[0028] The lower sealing seat 3 has sliding grooves at both ends. The contact surfaces on both sides of the sliding groove are inclined surfaces with the same slope as the inclined surfaces on both sides of the insert plate 4. The front contact surface of the sliding groove is also inclined.

[0034] This utility model discloses a grooved slide plate double-layer valve device. A drive mechanism 1 is fixed to an upper sealing seat 2 and a lower sealing seat 3. A seat sealing strip 5 is installed at the interface between the upper sealing seat 2 and the grooved lower sealing seat 3. A slide plate 4 is installed on the grooved lower sealing seat 3. End sealing strips 6 are installed at the ends of the upper sealing seat 2 and the grooved lower sealing seat 3. The end sealing strips 6 are pressed onto the slide plate 4 by an end sealing and pressing mechanism 7 installed on the upper sealing seat 2 and the grooved lower sealing seat 3. The slide plate 4 forms a rigid seal in close contact with the grooved lower sealing seat 3, and also forms a second flexible seal in close contact with the seat sealing strip 5. The end sealing strips 6 installed at the ends of the upper sealing seat 2 and the grooved lower sealing seat 3 can be one or multiple.
[0035] like Figure 1 As shown, the insert plate 4, which is located between the upper sealing seat 2 and the lower sealing seat 3 with a sliding groove, is in close contact with the lower sealing seat 3 with a sliding groove to form a rigid seal.
[0036] like Figure 2 As shown, the insert plate 4, which is set between the upper sealing seat 2 and the lower sealing seat 3 with a sliding groove, is in close contact with the seat body sealing strip 5 to form a second flexible seal.
[0037] This utility model has a good sealing effect. The insert plate, together with the lower sealing seat with the sliding groove and the sealing strip of the seat body, form a double seal, which prevents air leakage and dust accumulation, ensuring service life, convenient maintenance and repair, and high reliability.
