Abstract
The utility model discloses an anti-flying-out valve sleeve of a three-way valve of a single hydraulic prop. The anti-flying-out valve sleeve comprises protective boards (3), U-shaped boards (2) and an arc-shaped connection board (1). The two ends of the arc-shaped connection board (1) are bent to planar ends. Each planar end is located at one side of the concave portion of the arc-shaped connection board (1) and welded to one end of the corresponding U-shaped board (2). The protective boards (3) are welded to the outer side portions of the U-shaped boards (2). The anti-flying-out valve sleeve of the three-way valve of the single hydraulic prop has the advantages that potential safety hazards of flying out of the three-way valve are eliminated, the service life of the three-way valve is prolonged, the reliability of the three-way valve is improved, operation is easy and convenient, coal dust and waste rock are blocked from entering the three-way valve, and thus the three-way valve is protected.
Description
Technical field
The utility model relates to a kind of hydraulic prop safety device, specifically the anti-valve pocket that flies of a kind of single-body hydraulic prop.
Background technology
Hydraulic prop has the characteristics such as setting load is large, constant-resistance, safety and efficiently, is a kind of effective face timbering equipment that is applicable to China's national situation, has been widely used in the supporting of China's coal-mine down-hole.Triple-use valve is the heart of hydraulic prop, and the performance quality of peace directly affects work and the security performance of pillar.Owing to being subject to the impact of face pressure, can there is the phenomenon that triple-use valve flies valve in part pillar, often has because triple-use valve collapses the generation that flies casualty accident in mining area, threatens constructor's safety; The method that currently used solution single-body hydraulic prop collapses the problem of flying is to improve triple-use valve self structure, adopts that design processing is in this way more difficult and cost is higher.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of single-body hydraulic prop the anti-valve pocket that flies, and stops that triple-use valve collapses fly part by exterior protection device, eliminates at low cost triple-use valve and collapses the potential safety hazard flying.
To achieve these goals, the technical solution adopted in the utility model is: the anti-valve pocket that flies of a kind of single-body hydraulic prop, comprise backplate, U-shaped plate and arc junction plate, the two ends of described arc junction plate are bent into planar ends, this planar ends is positioned at a side of arc junction plate recess and one end of U-shaped plate welding, and the outside portion of described U-shaped plate is welded with backplate.
Also comprise handle, described handle is welded in the centre position of arc junction plate protuberance.
Backplate shape is identical with U-shaped plate side view.
The radius of described arc junction plate is greater than triple-use valve radius 1-2 centimetre.
The utility model has been eliminated the potential safety hazard that triple-use valve flies valve, and the working life that extended triple-use valve has improved the reliability of triple-use valve, simple to operation; And can stop in coal dust, spoil intrusion valve, protected triple-use valve.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: 1, arc junction plate, 2, U-shaped plate, 3, backplate, 4, handle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2: the utility model comprises backplate 3, U-shaped plate 2 and arc junction plate 1, the two ends of described arc junction plate 1 are bent into planar ends, this planar ends is positioned at a side of arc junction plate 1 recess and one end of U-shaped plate 2 welding, and the outside portion of described U-shaped plate 2 is welded with backplate 3.
Also comprise handle 4, described handle 4 is welded in the centre position of arc junction plate 1 protuberance, and the utility model is positioned on triple-use valve valve cylinder or it is taken off all convenient from valve cylinder.
The radius of described arc junction plate 1 is greater than triple-use valve radius 1-2 centimetre, more convenient the utility model is fastened on triple-use valve valve cylinder, and triple-use valve is better protected.
In use, only the utility model need to be stuck on triple-use valve valve cylinder, the untight inside portion of U-shaped plate 2 contacts with triple-use valve valve cylinder, triple-use valve both sides are sealed, can effectively triple-use valve be collapsed and fly to be partly blocked in the space being formed by U-shaped plate 2 and backplate 3, meanwhile, can also stop that coal dust, spoil fall in triple-use valve; When fluid injection, take off and anti-fly valve pocket, the utility model is directly stuck on valve cylinder after completing fluid injection, simple to operation.On handle 4, thin anchor chain can also be housed, prevent from flying the loss of valve pocket.
