Description

Technical Field

[0001] This invention relates to the field of valves, and more particularly to a handle valve. Background Technology

[0002] Manual valves are divided into turbine valves and handle valves. The structure of a turbine valve mainly includes a valve body, valve seat, valve stem, butterfly plate, and turbine device. It is opened and closed by rotating the handwheel to drive the internal gear of the turbine head. It is suitable for large-diameter valves. The main difference between a handle valve and a turbine valve is that the valve is opened and closed by a handle. It is connected to the butterfly plate through a valve shaft. The opening and closing angle is usually between 0 and 90 degrees. It has fast opening and closing speed and good flow regulation characteristics.

[0003] Most conventional valve handles currently available connect to the top of the valve body via a graduated toothed disc. Since both the valve body top and the toothed disc are circular, when large quantities of valves need to be packed horizontally, the circular shape of the valve body top and toothed disc causes the valves to be unevenly placed in the packaging box. This leads to easy rolling and collisions during transportation, low space utilization, and the need for additional padding materials, increasing costs and the risk of damage. During storage, stacking is difficult and handling is inconvenient, potentially occupying more space or creating safety hazards. Temporary storage is also prone to problems such as valve stem deformation or damage to the sealing surface due to rolling. Furthermore, most handles on the market lack a limiting structure, causing the handle to easily rub against other parts when the operator grips it tightly, resulting in impacts and wear, and reducing the handle's lifespan. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention proposes a limiting handle with a square base, and provides a valve that is easy to pack and transport safely.

[0005] A handle includes a handle body and a geared disc, wherein the handle body includes a fixed handle and a movable handle, the geared disc includes a geared disc base and a geared disc body, the geared disc base is square, and the geared disc body is disposed on the geared disc base; the solid part of the geared disc base is completely located below the geared disc.

[0006] Furthermore, the fixed handle and the movable handle are connected by a rotating component.

[0007] Furthermore, the fixed handle is provided with a first upper limit member, and the movable handle is provided with a first lower limit member. When the first upper limit member and the first lower limit member are in contact with each other, they restrict the downward movement space of the front end of the handle in the gripped state.

[0008] Furthermore, the fixed handle is provided with a second upper limit member, and the movable handle is provided with a second lower limit member. When the second upper limit member and the second lower limit member are in contact with each other, they restrict the upward movement space of the front end of the handle in the released state.

[0009] Alternatively, a second limiting element can be separately installed on the fixed handle to limit the upward movement of the front part of the handle when it is released.

[0010] Furthermore, the first upper limit member, the first lower limit member, the second upper limit member, and the second lower limit member are columnar protrusion structures.

[0011] Furthermore, the same spring is fitted onto both the first lower limit member and the first upper limit member.

[0012] Furthermore, the moving handle includes an engaging protrusion and a gripping portion.

[0013] Furthermore, when the first upper limit member and the first lower limit member are in contact with each other, the distance D between the lower surface of the engaging protrusion and the upper surface of the gear base is greater than 0.

[0014] Furthermore, one side of the toothed disc body includes engaging grooves spaced at certain intervals.

[0015] Furthermore, the toothed disc body has a scale on its upper surface on the side opposite to the engaging groove.

[0016] Furthermore, the fan-shaped angle formed by the engaging groove is 90 degrees.

[0017] Furthermore, the scale is divided into 0-90 degrees.

[0018] Furthermore, the toothed disc body has two third limiting members on its upper surface at a certain distance from both ends of the engagement groove.

[0019] Furthermore, the toothed disc body does not have a locking groove, and the two opposite corners of the scale are provided with fixing protrusions.

[0020] Furthermore, the fixing protrusion extends outward to be flush with the outer surface of the two corresponding corners of the gear base; the height of the fixing protrusion is the same as that of the gear body.

[0021] Furthermore, the fixing protrusion has a first fixing hole in the middle.

[0022] Furthermore, the gear disc is manufactured as a single piece.

[0023] A handle valve includes a valve body, a valve stem, and a top fixing seat, wherein the top fixing seat is square in shape and its size and shape are consistent with the toothed disc base.

[0024] Furthermore, when the top fixing seat and the gear base are fixed, the four sides of the top fixing seat and the four sides of the gear base are flatly positioned on four planes.

[0025] Furthermore, a second fixing hole is provided at the two corners of the top fixing seat corresponding to the first fixing hole.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. This invention adds a larger square toothed disc base under the circular toothed disc of the handle, increasing the thickness of the traditional toothed disc and providing better protection for the toothed disc. This reduces the impact and wear on the toothed disc itself or the toothed disc groove during transportation, storage, or use, and increases mechanical reliability and safety. The physical toothed disc base is directly and completely located below the toothed disc, and no additional materials are needed above or on the sides of the toothed disc, simplifying the structure and reducing processing costs.

[0028] 2. The present invention provides a first limiting member and a second limiting member on the handle, which can limit the upper and lower displacement space of the handle in different states of being gripped or released by the operator, and avoid unnecessary wear and damage to important positions such as the locking protrusion; by providing a third limiting member, the entire handle can be limited during rotation, preventing the handle from rotating out of the range required for actual use. The limiting structure better protects the handle and extends its service life.

[0029] 3. A handle valve of the present invention has a fixing seat on the top of the valve. Both the top fixing seat and the toothed disc base are square in shape and the same size, and the four sides are flat when fixed. This square fixing structure ensures stability even when the handle or valve body is packaged separately, or when the handle and valve are packaged as a combination. It also simplifies stacking, improves packaging efficiency, greatly reduces the risk of rolling and collisions during transportation, lowers the requirements for the filling materials used in the packaging, enhances safety and reliability, extends service life, and reduces costs.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] The embodiments of the present invention will be described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the scope of protection of the present invention.

[0046] like Figure 1 , 2 As shown, the valve handle of the present invention includes a handle body 1 and a gear disc 2. The handle body 1 includes a fixed handle 11 and a movable handle 12, which are connected by a rotating component. A first upper limit member 111 and a second upper limit member 112 are provided on the fixed handle 11, and a first lower limit member 121, a second lower limit member 122, a locking protrusion 123, and a gripping portion 124 are provided on the movable handle 12. Additionally, as... Figure 3 As shown, the same spring 125 is fitted onto the first upper limit member 111 and the first lower limit member 121. Figure 4 , 5 As shown, the gear disc 2 includes a gear disc base 21 and a gear disc body 22. One side of the gear disc body 22 includes engagement grooves 221 spaced at intervals. The spacing between the engagement grooves 221 can be set to be equidistant or non-equidistant as needed. A scale 222 is provided on the upper surface of the gear disc body 22 on the opposite side of the engagement grooves 221. The fan-shaped angle formed by the engagement grooves 221 is 90 degrees. The scale is divided into 0-90 degrees at certain intervals according to actual needs. Two third limiting members 223 are provided at a certain distance from both ends of the engagement grooves 221, so that the rotation angle can be limited when the handle is rotated horizontally. On the two opposite corners of the gear disc body 22 that do not have engagement grooves 221 and scale 222, there are fixing protrusions 23 extending outward to the side and flush with the gear disc base 21. The fixing protrusions 23 have a first fixing hole 24 in the middle, which is used to fix the entire gear disc 2 to the top of the valve by fixing elements such as bolts. Preferably, the entire gear disc 2 is made of the same material in one piece.

[0047] In another preferred embodiment, to reduce costs and simplify the manufacturing process, the second limiting member can be simplified, such as... Figure 3 , 7As shown, only a limiting member is provided on the fixed handle. The front end of the moving handle is smooth and no limiting member is provided. This structure can also achieve the function of limiting.

[0048] The working principle of the present invention is as follows: When the operator's finger tightly holds the grasping portion 124, the spring will be compressed, causing the front part of the moving handle 12 to move downward around the rotating member, so that the engaging protrusion 123 leaves the engaging groove 221. In such a state, the operator can, according to the required angle of opening and closing of the disc in the actual working condition, turn the handle by a certain angle and then make the handle point to a certain scale position on the scale table 222. After releasing the grasping portion 124, the spring returns to its original state, and the engaging protrusion 123 on the handle body 1 is engaged with the corresponding engaging groove 221 at the required position (as Figure 6 shown). During the rotation of the handle, the rotating shaft drives the valve stem 3 to rotate synchronously to achieve flow regulation.

[0049] As Figure 7 shown, when the operator tightly holds the handle, the first upper limiting member 111 and the first lower limiting member 121 are combined into the first limiting member. After they come into contact with each other, they will limit the further downward movement of the front end of the handle, avoiding the friction between the front end part (such as the engaging protrusion 123) and the upper surface of the gear disc base 21, which may cause wear of the handle. Further, it can be set that after the first upper limiting member 111 and the first lower limiting member 121 come into contact with each other, the lower surface of the engaging protrusion 123 is located above the upper surface of the gear disc base 21, and the distance D between the lower surface of the engaging protrusion and the upper surface of the gear disc base is greater than 0, completely avoiding their contact. By reasonably designing the first upper limiting member 111 and the first lower limiting member 121, the value of the distance D can be adjusted; preferably, the range of D is 0 < D < 5 cm; further, according to the actual situation, the range of D is 0 < D < 2 cm. As Figure 1-2 shown, when the operator releases the handle, the second upper limiting member 112 and the second lower limiting member 122 are combined into the second limiting member. After they come into contact with each other, they will limit the further upward movement of the front end of the handle, or as Figure 3 shown, the function of the second limiting member 1122 is the same, which is to avoid the collision or contact between the front end part (such as the engaging protrusion 123) and the inner surface of the handle housing, thereby improving the safety and stability of the handle in use and extending its service life. In order to make the operator's grasping comfortable, the grasping portion is designed to match the shape of the normal human finger when grasping, and an anti-slip coating can be applied to the grasping parts at the rear ends of the fixed handle 11 and the moving handle 12.

[0050] As Figure 8 、 9As shown, a handle valve includes a valve body 4, a valve stem 3, and a top fixing seat 5. Second fixing holes (not shown) are provided at two corresponding corners of the top fixing seat 5 and the gear plate base 21. The first fixing hole 24 and the second fixing hole are aligned, and the entire gear plate 2 is fixed to the top of the valve using bolts or other fixing elements. Both the top fixing seat 5 and the gear plate base 21 are square in shape and the same size. In the fixed state, the four sides of the top fixing seat 5 and the gear plate base 21 are flat. The square shape referred to in this invention is a cube or cuboid, with the top and bottom surfaces perpendicular to the four sides. Compared to existing technologies, the manual valve of this invention is very stable even when laid horizontally during packaging, simplifies stacking, improves packaging efficiency, greatly avoids rolling collisions during transportation, has lower requirements for the filling materials used in packaging, enhances safety performance, extends service life, and reduces costs.

[0051] like Figure 10 , 11 As shown, the number of engaging grooves 221 on the gear disc body 22 can be set to 5, 6, 7, 8, 9, 10, etc., and the number of engaging grooves 221 can be 5-30, or set according to actual adjustment needs. Figure 11 As shown, the fixed protrusion 23 may not be flush with the gear base 21, and its height may be lower than that of the gear base 21; for example Figure 10 As shown, the first fixing hole 24 can also be directly provided on the base 21, without the need for the protruding fixing protrusion 23; thus saving processing materials and processing steps. In addition, the number of the first fixing holes 24 can be 2-8, depending on the actual needs.

[0052] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
