Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to a small high-pressure ball-shaped hand-operated valve portable wrench. Background Technology

[0002] A high-pressure ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the valve stem. It is used in hydraulic machinery, hydraulic switches, natural gas, etc. When it is necessary to turn the valve, the tool usually used is a valve wrench.

[0003] In the existing technology, valve wrenches are mainly F-type valve wrenches and three-prong valve wrenches. Since three-prong valve wrenches are suitable for various valve operations, especially in towering drilling platforms and complex pipeline systems, they are more adaptable and therefore have a wider range of applications.

[0004] However, existing three-pronged valve wrenches are mostly simple in structure, consisting of a handle and three prongs fixed to the handle head. Such three-pronged valve wrenches cannot be used for pressure ball hand-operated valves of different sizes. A valve wrench disclosed in patent CN116394183 A can be adapted to valves of various sizes, but its structure is relatively complex. Since valve wrenches are commonly used tools and are used in large quantities, this increases production costs and makes them unsuitable for use by some small, medium and micro enterprises. Utility Model Content

[0005] In view of this, this utility model proposes a small high-pressure ball-shaped portable wrench for valves to solve the problem that existing valve wrenches are not suitable for valves of different sizes or are too expensive.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model provides a small high-pressure ball-shaped portable wrench for a rotary valve, including a handle, a mounting plate, and a pressure rod. The mounting plate has several mounting holes, and the pressure rod is inserted into the mounting holes. The mounting holes are evenly distributed on the sides of the inscribed isosceles triangle of the mounting plate. The end of the pressure rod is provided with a rotation limiting element, and one side of the mounting hole is provided with a rotation limiting groove that cooperates with the rotation limiting element.

[0008] Based on the above technical solutions, preferably, three mounting holes are provided on each side of the inscribed isosceles triangle of the mounting plate, and the three mounting holes are equally spaced.

[0009] Based on the above technical solutions, preferably, the rotation limiting component is a cross-shaped frame and the rotation limiting groove is a cross-shaped groove.

[0010] Based on the above technical solutions, preferably, the pressure rod is provided with a threaded section, and a nut is screwed onto the threaded section.

[0011] Based on the above technical solutions, preferably, a nut groove is provided on the other side of the mounting hole for use with a nut.

[0012] Based on the above technical solutions, preferably, the nut groove is located inside the mounting hole, and the rotation limiting groove is located outside the mounting hole.

[0013] Based on the above technical solutions, preferably, the handle is provided with an anti-slip sleeve.

[0014] This utility model of a small, high-pressure ball-shaped hand-operated valve portable wrench has the following advantages over existing technologies:

[0015] 1. The position of the pressure rod can be adjusted according to the size of the pressure ball hand valve handle, which can adapt to different specifications of pressure ball hand valve handles;

[0016] 2. It has a simple structure, is easy to operate, portable and labor-saving, and has a low production cost, making it suitable for use by small, medium and micro enterprises. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] See Figure 1 The portable high-pressure ball valve wrench of this utility model includes a handle 1, a mounting plate 2 and a pressure rod 3; the mounting plate 2 is provided with a plurality of mounting holes 21, and the pressure rod 3 is inserted into the mounting holes 21.

[0025] See Figure 3 A number of mounting holes 21 are evenly distributed on the sides of the inscribed isosceles triangle of the mounting plate 2; in this utility model, three mounting holes 21 are provided on each side of the inscribed isosceles triangle of the mounting plate 2, and the three mounting holes 21 are equally spaced.

[0026] See Figure 3 For lines a, b, or c, if an F-type wrench is required, insert the two pressure rods 3 into the two mounting holes 21 on line a, line b, or line c, respectively. Of course, this is not limited to these two types of lines. Figure 3 The three straight lines a, b, or c in the figure have different distances between the two mounting holes 21 on different straight lines, and the distance between the two pressure rods 3 of the F-type wrench is different, which can be used for different specifications of pressure ball hand valve handles.

[0027] See Figure 4 In triangles A and B, if a three-pronged valve wrench is needed, the three pressure rods 3 are inserted into the mounting holes 21 at the three corners of the triangle, for example, the mounting holes 21 at the three corners of triangle A, or the mounting holes 21 at the three corners of triangle B; of course, this is not limited to... Figure 4 The two triangles A or B in the three-pronged valve wrench have different side lengths, and the distance between the three pressure rods 3 is different, which can be used for different specifications of pressure ball hand valve handles.

[0028] See Figure 2 The pressure rod 3 has a rotation limiting member 33 at its end, and a rotation limiting groove 23 that mates with the rotation limiting member 33 is provided on one side of the mounting hole 21. In this invention, the rotation limiting member 33 is a cross-shaped bracket, and the rotation limiting groove 23 is a cross-shaped groove. The pressure rod 3 has a threaded section 31, and a nut 32 is screwed onto the threaded section 31. A nut groove 22 that mates with the nut 32 is provided on the other side of the mounting hole 21. In this invention, the nut 32 is a hexagonal nut, and the nut groove 22 is hexagonal.

[0029] In this invention, the nut groove 22 is located inside the mounting hole 21, and the rotation limiting groove 23 is located outside the mounting hole 21.

[0030] After the pressure rod 3 is inserted from the outside to the inside of the mounting plate 2, the rotation limiting member 33 at the end of the pressure rod 3 is engaged in the rotation limiting groove 23. Due to the cross-shaped arrangement of the rotation limiting member 33 and the rotation limiting groove 23, the pressure rod 3 cannot rotate freely.

[0031] After the nut 32 is threaded onto the threaded section 31, it is screwed into the nut groove 22, which can fix the position of the pressure rod 3 inserted into the mounting hole 21. Since both the nut 32 and the nut groove 22 are hexagonal, when the nut 32 is screwed into the nut groove 22, it can further prevent the pressure rod 3 from rotating freely.

[0032] Preferably, the handle 1 is provided with an anti-slip sleeve 11. This provides an anti-slip function when the operator uses the wrench.

[0033] During operation, when the operator switches the high-pressure ball valve, they can select the appropriate mounting hole 21 according to the different specifications of the pressure ball valve handle, insert the pressure rod 3 into the mounting hole 21, lock it with the nut 32, and then insert the pressure rod 3 into the valve handle. Under the action of the handle 1, the valve is opened or closed.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
