Technical Field

[0001] This utility model relates to the field of shut-off valve technology, and more specifically, to a shut-off valve. Background Technology

[0002] In existing industrial ore pipeline applications and management, conventional products use gate valves and knife valves as the main control units. Traditional valve chambers are prone to blockages and material accumulation, making it impossible to properly manage the feeding process of the production line. The blockage is usually resolved manually with simple tools to pry and knock away the ore, which cannot achieve automated industrial upgrading and also poses safety issues. Utility Model Content

[0003] Therefore, in order to solve the problem that manually moving or knocking away blocked ore with simple tools can easily lead to safety hazards, this utility model provides a shut-off valve, the specific technical solution of which is as follows:

The anti-jamming ring is slidably connected to one side of the moving end of the switch assembly, and the scraper ring is slidably connected to the other side of the moving end of the switch assembly.

[0007] The aforementioned shut-off valve features a first channel for ore to pass through. A switching assembly within the conduit allows for control of the first channel's connectivity, enabling automated management and control. When blockage forms within the valve body, the switching assembly repeatedly taps the ore, causing it to rotate and be removed from the valve. This shut-off valve eliminates the safety hazards associated with manually manipulating and tapping blocked ore with simple tools.

[0008] Furthermore, the switching assembly includes a gate and a drive block. The valve body is also provided with an opening for the gate to pass through back and forth, and the opening is connected to the first channel. The drive block is disposed on the valve body, and the output end of the drive block is connected to the gate. The drive block is used to drive the gate to repeatedly pass through the opening. The gate and the drive block cooperate to control the connection state of the first channel.

[0009] Furthermore, the cross-section of the anti-jamming ring is arranged in the shape of a right-angled trapezoid.

[0010] Furthermore, the cross-section of the scraper ring is arranged in the shape of a right trapezoid.

[0011] Furthermore, the valve body includes a through pipe and a sealed chamber, the first channel is located inside the through pipe, the opening is located on the through pipe, the sealed chamber is located on the through pipe, and the opening is connected to the first channel and the sealed chamber respectively.

[0012] Furthermore, the drive block is disposed on the sealed chamber, and the output end of the drive block is disposed inside the sealed chamber and connected to the gate.

[0013] Furthermore, the sealed chamber is equipped with a high-temperature resistant and explosion-proof limit switch, which is used to detect the movement of the output end of the drive block.

[0014] Furthermore, the drive block is a hydraulic cylinder with a buffer.

[0015] Furthermore, a blade is provided at the end of the gate away from the drive block. Attached Figure Description

[0025] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0026] like Figure 1-2 As shown, a shut-off valve in one embodiment of the present invention includes a valve body 1 and a switch assembly 2; the valve body 1 has a first channel 3 penetrating through the valve body 1, and an anti-jamming ring 4 and a scraping ring 5 are provided on the inner surface of the first channel 3; the switch assembly 2 is disposed on the valve body 1, and the switch assembly 2 is used to control the connection state of the first channel 3; the anti-jamming ring 4 is slidably connected to one side of the moving end of the switch assembly 2, and the scraping ring 5 is slidably connected to the other side of the moving end of the switch assembly 2.

[0027] The aforementioned shut-off valve, by providing a first channel 3, facilitates the passage of ore through the valve; the through pipe 11 is equipped with a switch assembly 2 to control the connection status of the first channel 3, achieving automated management and control; when a blockage forms inside the valve body 1, the switch assembly 2 of the through pipe 11 repeatedly taps the ore, causing the ore stuck inside the valve body 1 to rotate and be removed from the valve body 1. This shut-off valve solves the safety hazard problem caused by manually moving and tapping blocked ore with simple tools.

[0028] like Figure 1-2As shown, in one embodiment, the switch assembly 2 includes a gate 22 and a drive block 21. The valve body 1 is also provided with an opening for the gate 22 to pass through repeatedly, and the opening is connected to the first channel 3. The drive block 21 is disposed on the valve body 1, and the output end of the drive block 21 is connected to the gate 22. The drive block 21 is used to drive the gate 22 to repeatedly pass through the opening. The gate 22 and the drive block 21 cooperate to control the connection state of the first channel 3. The anti-jamming ring 4 has a cross-section in the shape of a right trapezoid. The scraper ring 5 also has a cross-section in the shape of a right trapezoid. Thus, by driving the gate 22 to repeatedly pass through the opening through the drive block 21, the ore is repeatedly struck, which facilitates the rotation of the ore stuck in the valve body 1 and its removal from the valve body 1.

[0029] like Figure 1-2 As shown, in one embodiment, the valve body 1 includes a through pipe 11 and a sealed chamber 12. The first channel 3 is disposed within the through pipe 11, and the opening is disposed on the through pipe 11. The sealed chamber 12 is disposed on the through pipe 11, and the opening communicates with both the first channel 3 and the sealed chamber 12. The drive block 21 is disposed on the sealed chamber 12, and the output end of the drive block 21 is disposed within the sealed chamber 12 and connected to the gate 22. Thus, by providing the sealed chamber 12, the drive block 21 is protected, preventing damage to it.

[0030] like Figure 1-2 As shown, in one embodiment, a high-temperature resistant explosion-proof limit switch 6 is provided inside the sealed chamber 12. The high-temperature resistant explosion-proof limit switch 6 is used to detect the travel distance of the output end of the drive block 21. The drive block 21 is a hydraulic cylinder with a buffer. A blade is provided at the end of the gate plate 22 away from the drive block 21. Thus, by providing the high-temperature resistant explosion-proof limit switch 6, the travel distance of the output end of the drive block 21 is prevented from exceeding the set travel distance, thus avoiding safety issues. The blade facilitates the cutting of ore.
