Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a gate valve assembly that can achieve low residue. Background Technology

[0002] A slide gate valve is a valve that achieves a tight seal between its valve plate and seat. Its advantages include a smooth, unobstructed flow path, preventing media blockage, and full-bore flow capability. Its sealing structure can be either soft or hard seal. However, the slide gate is typically located in the middle of the valve body, creating a gap between the top of the valve plate and the valve inlet. When the valve plate is closed, some material falls onto it. This gap can prevent accurate calculation of the conveyed material volume when precisely controlling its volume. Utility Model Content

[0003] The purpose of this invention is to provide a gate valve assembly that can achieve low residue, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a slide gate valve assembly capable of achieving low residue, comprising a valve body, a valve stem drive fixedly connected to the outer wall of the right side of the valve body, a bracket provided above the valve stem drive, a sliding slide plate for sealing and blocking the valve body fixedly connected to the upper end of the bracket, the top ends of the bracket and the sliding slide plate being inserted into the valve body, the power output end of the valve stem drive being fixedly connected to the top of the bracket, a sealing strip fixedly connected to the inner wall of the valve body, a top plate for controlling low residue material provided at the upper end of the sliding slide plate, at least four rubber telescopic blocks fixedly connected between the top plate and the sliding slide plate, the rubber telescopic blocks being used to control the distance between the sliding slide plate and the top plate, a control plate for changing its position height fixedly connected to the right side of the top plate, a pressing block for changing its position height provided to the right side of the control plate, a side plate fixedly connected to the upper end of the bracket, and an electric actuator fixedly connected between the side plate and the pressing block.

[0005] Preferably, the length of the top plate is less than the length of the sliding insert, the length of the top plate is the same as the length of the valve body cavity, and the length of the bracket is greater than the length of the sliding insert.

[0006] Preferably, the rubber expansion block has a prismatic structure and a through hole in the middle.

[0007] Preferably, the lower end of the control board is provided with a guide groove, the bottom of the left side of the guide groove is an inclined structure, and the left side of the extrusion block is an inclined surface.

[0008] Preferably, a connecting groove is provided at the connection between the sliding plate and the valve body, and the sealing strip is fixedly connected to the upper left corner of the connecting groove.

[0009] Preferably, the upper surface of the control plate is provided with a sealing groove, and the lower end of the sealing strip is fixedly connected with a sealing protrusion. When the top plate is snapped into the valve body, the sealing protrusion and the sealing groove are snapped together.

[0010] Preferably, the inner wall of the valve body is provided with an adjusting bracket, and the bracket is slidably connected to the upper end of the adjusting bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are: a top plate is set above the sliding slide plate of the traditional slide plate valve.

[0018] Please see Figure 1-4This utility model provides a technical solution: a gate valve assembly capable of achieving low residue, comprising a valve body 1, a valve stem drive 4 fixedly connected to the outer wall of the right side of the valve body 1, a bracket 3 provided above the valve stem drive 4, a sliding gate plate 6 for sealing and blocking the valve body 1 fixedly connected to the upper end of the bracket 3, the top ends of the bracket 3 and the sliding gate plate 6 being inserted into the valve body 1, the power output end of the valve stem drive 4 being fixedly connected to the top of the bracket 3, a sealing strip 14 fixedly connected to the inner wall of the valve body 1, and a top plate 2 for controlling low residue materials provided at the upper end of the sliding gate plate 6. At least four rubber telescopic blocks 7 are fixedly connected between the top plate 2 and the sliding insert plate 6. The rubber telescopic blocks 7 are used to control the distance between the sliding insert plate 6 and the top plate 2. A control plate 11 is fixedly connected to the right side of the top plate 2 to change its position height. A pressing block 8 is provided on the right side of the control plate 11 to change its position height. A side plate 9 is fixedly connected to the upper end of the bracket 3. An electric push rod 10 is fixedly connected between the side plate 9 and the pressing block 8. The valve stem drive 4 drives the bracket 3 to move, thereby changing the position of the sliding insert plate 6 and the top plate 2, and inserting or pulling the sliding insert plate 6 and the top plate 2 into or out of the valve body 1.

[0019] The length of the top plate 2 is less than the length of the sliding slide plate 6. The length of the top plate 2 is the same as the length of the inner cavity of the valve body 1. The length of the bracket 3 is greater than the length of the sliding slide plate 6, which makes it convenient for the bracket 3 to control the movement of the sliding slide plate 6, thereby changing the position of the top plate 2. This allows the top plate 2 to fill the excess space between the valve body and the sliding slide plate 6, thereby reducing residual material.

[0020] The rubber telescopic block 7 has a prismatic structure and a through hole in the middle. The lower end of the control plate 11 has a guide groove 12. The bottom of the guide groove 12 on the left side is inclined. The left side of the extrusion block 8 is inclined.

The extrusion block 8 extrudes the side wall of the guide groove 12, causing the top plate 2 to move upward and fill and seal the inside of the valve body 1.

[0021] A connecting groove is provided at the connection between the sliding slide plate 6 and the valve body 1. The sealing strip 14 is fixedly connected to the upper left corner of the connecting groove. The upper surface of the control plate 11 is provided with a sealing groove 13. A sealing protrusion 15 is fixedly connected to the lower end of the sealing strip 14. When the top plate 2 is snapped into the inside of the valve body 1, the sealing protrusion 15 and the sealing groove 13 snap together. The sealing strip can seal the connection between the sliding slide plate 6 and the connecting groove to prevent material leakage from the sliding slide plate. When the sealing protrusion 15 and the sealing groove 13 snap together, the top plate 2 can be positioned and the sealing performance can be ensured.

[0022] An adjusting bracket 5 is provided on the inner wall of the valve body. The bracket 3 is slidably connected to the upper end of the adjusting bracket 5. The adjusting bracket 5 can support and guide the movement of the bracket 3.
