Description

Technical Field

[0001] The present application relates to the technical field of construction tools, and in particular to an auxiliary tool suitable for rapid replacement of multi-caliber wafer-type valves. Background Art

[0002] Wafer valves are important pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters of the conveying medium. They are easy to open and close, labor-saving, have low fluid resistance, achieve two-way sealing, and have a long service life, making them widely used in the construction industry. The commonly used diameter is DN50-DN1200.

[0003] At present, the existing valve flange connections have high tightness requirements. The replacement of small-diameter valves is slightly simpler, but the connections of valves of DN200 and above are abnormally tight. The traditional replacement method is generally to manually use a crowbar to gradually expand the flange outward, which has problems such as complex operation and low work efficiency. During the operation, it is more likely to cause damage to the valve and pipe flange, affecting its use effect.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that the replacement efficiency of the wafer-type valve is low. Utility Model Content

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses an auxiliary tool suitable for rapid replacement of multi-caliber wafer-type valves. Figure 1 and Figure 2 The auxiliary tool suitable for quick replacement of multi-caliber wafer-type valves includes a support 1 and a jack 2. Two support members 1 are relatively arranged, and the jack 2 is arranged between the two support members 1. The two support members 1 are pushed by the jack 2 to separate the two flanges 4 at both ends of the wafer-type valve 3, thereby improving the replacement efficiency of the wafer-type valve 3.

[0033] The support member 1 is a support plate, which includes a horizontal plate 11 and a vertical plate 12. The ends of the horizontal plate 11 and the vertical plate 12 are fixedly connected to form an "L"-shaped plate. A reinforcing plate 14 is also fixedly connected between the horizontal plate 11 and the vertical plate 12. Two reinforcing plates 14 are provided, and the two reinforcing plates 14 are respectively arranged at the ends of both sides of the horizontal plate 11 and the vertical plate 12. The reinforcing plates 14 improve the integrity of the horizontal plate 11 and the vertical plate 12, and enhance the structural strength of the support member 1.

[0034] Two clamping plates 13 are relatively fixed on the side of the vertical plate 12 facing away from the horizontal plate 11. The two clamping plates 13 are arranged at intervals, and the space formed between the two clamping plates 13 is used to clamp onto the flange 4. A jacking bolt 131 is screwed into one of the clamping plates 13. By tightening the jacking bolt 131, the jacking bolt 131 abuts against the flange 4, thereby fixing the support member 1 on the flange 4; the jacking bolts 131 on the two relatively arranged support members 1 are arranged on two clamping plates 13 far away from each other, so that it is more convenient for operators to screw the jacking bolts 131.

[0035] Furthermore, the position of the clamping plate 13 on the transverse plate 11 can be adaptively selected according to the distance between the two flanges 4 without too many restrictions, and it is only necessary to ensure that the installation of the two support members 1 does not conflict with each other.

[0036] A pad 111 is fixed on one side of the horizontal plate 11 close to the vertical plate 12. The pad 111 is arranged at a position with high strength, so it can withstand the thrust of the jack 2 and avoid damage to the horizontal plate 11. A groove 112 is provided on the pad 111, and the groove 112 is located in the middle of the pad 111. The groove 112 always accommodates the free end of the jack 2, so that the jack 2 is placed more firmly.

[0037] A fixing plate 113 is fixed on the side of the cushion block 111 facing away from the horizontal plate 11. The fixing plate 113 is an "L"-shaped structure. One end of the fixing plate 113 is fixedly connected to the cushion block 111, and the opening of the fixing plate 113 is set away from the horizontal plate 11, and a fixed space is formed between the fixing plate 113 and the cushion block 111; two fixing plates 113 are provided, the two fixing plates 113 are arranged at intervals, and the two fixing plates 113 are respectively located on both sides of the groove 112, and a clamping space is formed between the two fixing plates 113; when installing the jack 2, the base of the jack 2 can be inserted into the fixed space, and the free end of the jack 2 can be inserted into the clamping space, thereby further improving the stability of the jack 2 in use.

[0038] Reference Figure 3When in use, it is necessary to install multiple groups of support members 1 on the flange 4, for example, install two groups of support members 1 along the circumference of the flange 4, and keep the angle of the two groups of support members 1 at about 150°, or install three groups of support members 1, and keep the angle of adjacent support members 1 at about 120°, so that the flange 4 is evenly stressed and deformation is avoided.

[0039] The implementation principle of the auxiliary tool for the rapid replacement of multi-caliber wafer valves in the embodiment of the present application is as follows: multiple sets of support members 1 and jacks 2 are installed on the flanges 4 on both sides of the wafer valve 3, and then the hydraulic jacks 2 are evenly stressed at the same time to gradually increase the degree of extrusion, so that a certain movable gap appears between the wafer valve 3 and the pipeline flange 4, and the valve can be easily pushed and pulled out of the pipeline clamping state manually. Keep the jack 2 in the same state, repeat the action to replace the new wafer valve 3, and after the change of the wafer valve 3 is completed, the bolts are pierced and the jacks 2 are evenly released. After completion, the support members 1 and jacks 2 are removed, and the clamping bolts are tightened to complete the valve replacement work.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
