Description

Technical Field

[0001] This utility model belongs to the field of special valve technology, specifically relating to a wear-resistant slag discharge valve with a buffer structure. Background Technology

[0002] A slag discharge valve is a type of valve primarily used to discharge or isolate solid particles, slurries, sediments, and other impurities from pipeline media. Its main function is not flow regulation, but rather to achieve reliable shut-off and unobstructed slag discharge. Current slag discharge valves mainly use a gate to cut off slag particles; however, an excessively thick gate can easily cause slag particles to accumulate at the bottom of the valve body when cutting off slag particles, leading to poor sealing. Utility Model Content

[0003] The purpose of this utility model is to provide a wear-resistant slag discharge valve with a buffer structure to solve the problem that in the prior art, when the gate plate of the slag discharge valve is too thick, slag particles are easily accumulated at the bottom of the valve body, resulting in poor sealing.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wear-resistant slag discharge valve with a buffer structure includes a valve assembly and a drive assembly. The valve assembly is composed of a valve body and a first connecting flange and a second connecting flange located on the left and right sides of the valve body. The drive assembly is installed on top of the valve body. The drive assembly includes a hydraulic drive component and a main gate plate installed on the output end of the hydraulic drive component. The main gate plate is movably disposed within the valve body to control the opening and closing of the valve. The main gate plate also contains a secondary gate plate for pre-cutting slag particles.

[0006] Preferably, the bottom surface of the main gate plate is provided with a narrow mounting groove in the center, and the main gate plate is provided with a mounting chamber that communicates with the narrow mounting groove. A hydraulic drive component two is fixedly installed on the top surface of the mounting chamber, and the output end of the hydraulic drive component two is connected to a connecting seat. The auxiliary gate plate is fixedly installed on the bottom surface of the connecting seat.

[0007] Preferably, the connecting seat and the auxiliary gate are slidably disposed in the mounting narrow groove, the auxiliary gate is hollow inside, and two sets of air blowing holes are symmetrically opened on the left and right sides of the auxiliary gate for dispersing and blowing the pre-cut slag particles in two directions.

[0008] Preferably, the connecting seat is equipped with a miniature air pump that communicates with the interior of the secondary gate plate, which is used to provide a power source for the air blowing of the two sets of air blowing holes.

[0009] Preferably, the thickness of the secondary gate plate is one-quarter of the thickness of the main gate plate, and the thickness of the connecting seat and the secondary gate plate are the same.

[0010] Preferably, both the first hydraulic drive component and the second hydraulic drive component are hydraulic push rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model incorporates a movable secondary gate plate within the main gate plate, which pre-cuts the slag particles in the valve body before the main gate plate. Then, in conjunction with the blowing effect of the two sets of air holes on both sides of the secondary gate plate, the main gate plate moves downward to open up space. The pre-cutting of the secondary gate plate provides a buffer for the downward movement of the main gate plate, thereby minimizing the accumulation of slag particles at the bottom of the valve body and ensuring the sealing effect after sealing.

[0013] 2. The connecting seat of this utility model is equipped with a miniature air pump that communicates with the interior of the auxiliary gate plate. The layout is ingenious and reasonable, and it can provide a power source for the blowing of the two sets of air holes, which is stable and reliable. Attached Figure Description

[0022] Reference Figures 1-3 As shown, this utility model provides a wear-resistant slag discharge valve with a buffer structure, including a valve assembly 1 and a drive assembly 2. The valve assembly 1 is composed of a valve body 11 and a first connecting flange 12 and a second connecting flange 13 located on the left and right sides of the valve body 11. The drive assembly 2 is installed on the top of the valve body 11. The drive assembly 2 includes a hydraulic drive component 21 and a main gate 22 installed on the output end of the hydraulic drive component 21. The main gate 22 is movably disposed in the valve body 11 to control the opening and closing of the valve. The main gate 22 is also provided with a secondary gate 5 for pre-cutting slag particles. The pre-cutting by the secondary gate 5 provides a buffer for the downward movement of the main gate 22, thereby maximizing the avoidance of slag particles accumulating at the bottom of the valve body 11 and ensuring the isolation effect after sealing.

[0023] The bottom surface of the main gate plate 22 is provided with a narrow mounting slot 222 in the center, and the main gate plate 22 is provided with a mounting chamber 221 that communicates with the narrow mounting slot 222. The mounting chamber 221 is used for the placement of the hydraulic drive component 3. The hydraulic drive component 3 is fixedly installed on the top surface of the mounting chamber 221. The output end of the hydraulic drive component 3 is connected to the connecting seat 4. The auxiliary gate plate 5 is fixedly installed on the bottom surface of the connecting seat 4 and is slidably inserted into the narrow mounting slot 222.

[0024] Furthermore, the connecting seat 4 and the auxiliary gate 5 are slidably disposed in the mounting narrow groove 222. The auxiliary gate 5 is hollow inside, and two sets of air blowing holes 51 are symmetrically opened on the left and right sides of the auxiliary gate 5 for dispersing and blowing the pre-cut slag particles in two directions. Thus, by embedding the movable auxiliary gate 5 inside the main gate 22, the slag particles in the valve body 11 can be pre-cut before the main gate 22. Then, in conjunction with the blowing effect of the two sets of air blowing holes 51 on both sides of the auxiliary gate 5, the main gate 22 is lowered to open up space.

[0025] In a further embodiment, the connecting seat 4 is embedded with a miniature air pump that communicates with the interior of the secondary gate 5. The layout is ingenious, reasonable, stable and reliable, and it is used to provide a power source for the air blowing of the two sets of air blowing holes 51.

[0026] In a further embodiment, the thickness of the secondary gate 5 is one-quarter of the thickness of the main gate 22, and the thicknesses of the connecting seat 4 and the secondary gate 5 are the same.

[0027] In this embodiment, the sheet-like thin design of the auxiliary gate 5 can better cut off the slag particles at the bottom of the stack valve body 11.

[0028] In a further embodiment, both hydraulic drive component 21 and hydraulic drive component 3 are hydraulic push rods, which are readily available, easy to assemble, and easy to use.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
