A new type of gate valve suitable for silo pipeline

Abstract

This utility model discloses a novel gate valve suitable for silo pipelines, belonging to the field of valve technology. It solves the problems of ordinary gate valves such as jamming, difficult opening and closing, and incomplete closure. This utility model includes a silo pipeline with a gate flange at its lower end. A rail guide assembly is connected to the lower end of the gate flange, and a gate is nested inside the rail guide assembly. Multiple driven shafts are slidably connected to the lower part of the gate. The large clearance and external visibility of the rail guide assembly allow operators to promptly clear materials, preventing the gate from getting stuck. Furthermore, the reciprocating motion of the gate on the driven shafts provides flexibility in opening and closing, reducing labor costs.

Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and specifically relates to a novel gate valve suitable for silo pipelines. Background Technology

[0002] Storage silos typically have various types of gate valves installed at their discharge ports to control material discharge. Depending on the process conditions, some silos require frequent opening and closing of the gate valves to discharge materials, while others require the gate valves to be completely closed before maintenance of the downstream connected equipment to prevent material leakage. After a period of use, gate valves often experience problems such as material getting stuck in the valve slide, preventing the gate from closing properly, and making it difficult to open and close the gate. These issues necessitate manual intervention, using a sledgehammer to tap the gate and slide to loosen the adhesive while simultaneously opening and closing the valve – a time-consuming and labor-intensive operation. Utility Model Content

[0003] The purpose of this invention is to provide a novel gate valve that is flexible in its opening and closing for use in silo pipelines, aiming to solve the problems in the background art where the gate valve is affected by material adhesion, resulting in incomplete and laborious closure.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A novel gate valve for silo pipelines includes a silo pipeline with a gate flange at the lower end. A rail guide assembly is connected to the lower end of the gate flange. A gate is nested inside the rail guide assembly. Multiple driven shafts are slidably connected to the lower part of the gate.

[0005] Furthermore, a hydraulic push rod is fixedly connected to the outside of the gate.

[0006] Furthermore, a sealing ring is provided between the rail slide assembly and the driven shaft.

[0007] Furthermore, each driven shaft is provided with bearing assemblies at both ends, and an end cap is provided on the outside of the bearing assembly.

[0008] The beneficial effects of this invention are as follows: The use of a slide rail assembly with a large and externally observable gap allows for timely cleaning of any material adhering to the slide rail, preventing the gate from jamming due to material buildup. The hydraulic push rod drives the gate to reciprocate on the driven shaft, ensuring flexible gate operation. The bearing rotation reduces resistance to the gate's reciprocating motion, achieving a labor-saving effect. A sealing ring between the slide rail assembly and the driven shaft effectively prevents dust leakage, solving the problem of material leakage. The end cap secures the bearing assembly and the driven shaft, limiting axial movement of the driven shaft and preventing it from falling off. The device is flexible and easy to operate, reducing manual labor intensity and achieving flexible gate operation. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 As shown, a new type of gate valve suitable for silo pipelines includes a silo pipeline 1, a gate flange 2 at the lower end of the silo pipeline 1, and a rail guide assembly 5 welded and fixed at the lower end of the gate flange 2. The rail guide assembly 5 replaces the groove guide, and its guide clearance is larger and externally observable, which can promptly clean up material adhesion inside the guide. A gate 4 is nested inside the rail guide assembly 5, and multiple driven shafts 7 are slidably connected to the lower part of the gate 4.

[0013] Specifically, a hydraulic push rod 3 is fixedly connected to the outside of the gate plate 4. The hydraulic push rod 3 controls the extension and retraction of the gate plate 4 with the help of an external hydraulic cylinder, so as to realize the opening and closing of the gate plate 4.

[0014] Specifically, a sealing ring 6 is provided between the rail slide assembly 5 and the driven shaft 7 to prevent material leakage and achieve a good sealing effect.

[0015] Specifically, each driven shaft 7 is provided with bearing assemblies 8 at both ends. The rotation of the bearings can reduce the resistance when the gate 4 reciprocates. An end cover 9 is provided on the outside of the bearing assembly 8. The end cover 9 fixes the driven shaft 7 and the outside of the bearing assembly 8, restricts the axial movement of the driven shaft 7, prevents the driven shaft 7 from falling off, and further plays a protective role.

[0016] In practical applications, this utility model is assembled according to the above connection relationship. Depending on the actual site conditions, two or more sets of driven shaft 7 and bearing assembly 8 can be installed. When two sets are installed, driven shaft 7 is installed on rail slide assembly 5, and bearing assembly 8 is installed at both ends of driven shaft 7. The bearing assembly is fixed to the outside of rail slide assembly 5 with bolts.

[0017] After multiple driven shafts 7 and bearing assemblies 8 are installed, the hydraulic push rod 3 applies tension to the gate 4 with the help of an external hydraulic cylinder or solenoid valve. The gate 4, through high-strength bearings, relies on the rotation of the bearing assembly 8 to reduce movement resistance and easily moves on the driven shafts 7, thus opening the gate 4. The material falls under gravity for conveying. After the material is discharged, the hydraulic push rod 3 continues to control the gate 4 to close. The gate 4 and the gate flange 2 are tightly pressed together to ensure its sealing performance, and the sealing ring 6 further ensures that there is no material leakage at the shaft end. The entire device achieves flexible opening and closing of the gate 4, reduces manpower consumption, and ensures good sealing performance.
