Problems solved by technology

[0002] In the case of large-diameter and super-large-diameter pipelines such as iron and steel and metallurgical industry pipelines, when sealing holes under pressure without continuous transmission, it is necessary to use special valves to seal the medium in the pipeline. , first of all, the valves used are large in size and weight, such as DN1800 valves (the weight can reach nearly 20 tons), and secondly, due to the large diameter of the pipeline, the valve is large in size and heavy in weight. Although there is a valve support seat, there is still a big safety hazard to the safe operation of the pipeline; moreover, the existing heavy valves are extremely inconvenient during transportation and moving, which in turn leads to an increase in transportation costs and labor costs

Embodiment 1

[0030] Embodiment 1: A large-diameter valve with a hydraulic external gate, see Figure 1 to Figure 6 .

[0031] In this design, the large-diameter valve with a hydraulic external gate includes a valve body and a gate 3; a round hole is opened on the valve body, and an annular gate guide groove 17 is arranged on the inner wall of the round hole. The guide groove 17 is U-shaped, and one end of the valve body There is a through hole that runs through the end of the valve body and communicates with the guide groove. In this design, the valve body includes an upper body 1 and a lower body 2. The upper body 1 and the lower body 2 are fixedly connected by multiple bolts. At the same time, the upper body 1 and lower body 2 are provided with openings with the same diameter, and a U-shaped step is provided on the inner wall of the opening where upper body 1 and lower body 2 are docked. The opening of the hole constitutes the circular hole, and the circular hole is used for fluid circu...

Abstract

The invention provides a hydraulic external flashboard large-diameter valve which is novel in structural design and suitable for large-caliber pipelines. The hydraulic external flashboard large-diameter valve includes a valve body and a flashboard; the valve body is provided with a circular hole, the inner wall of the circular hole is provided with a circular flashboard guide groove, one end of the valve body is provided with a through hole penetrating through the end of the valve body and penetrating through the guide groove, the guide groove is rectangular, the flashboard penetrates throughthe through hole and is located in the guide groove, and the flashboard can slide in the guide groove; and the exterior of the valve body is fixedly provided with an oil cylinder, and a pushing shaftof the oil cylinder is connected with the end of the flashboard and can drive the flashboard to move in the guide groove.

Description

technical field [0001] The invention relates to the technical field of valves used for pressure opening and sealing of ultra-large-diameter pipelines without continuous transmission, and in particular to a large-diameter valve with a hydraulic external gate.
