Description

Technical Field

[0001] The utility model relates to the technical field of ball valve equipment, in particular to an adjustable straight-through ball valve. Background Art

[0002] Ball valves can be divided into pneumatic ball valves, electric ball valves and manual ball valves according to different driving methods. Ball valves can be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat surfacing with hard alloy, and is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, shunt and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels.

[0003] The prior art with the publication number of CN221628896U provides an adjustable straight-through ball valve, which includes a valve sleeve. A valve seat one and a valve seat two are respectively fixedly connected to both sides of the valve sleeve. A valve core located between the valve seat one and the valve seat two is rotatably arranged inside the valve sleeve. A valve rod rotatably arranged inside the valve sleeve is fixedly connected to the valve core. A push rod is elastically slidably arranged inside the valve sleeve through a spring. A groove for cooperating with the push rod is arranged on the outer part of the valve rod. The beneficial effect of the utility model is that when the valve rod rotates, the push rod is pushed out of one groove and then enters another groove. The distances between multiple grooves are the same, that is, each groove corresponds to one gear position, that is, the rotation angle of the valve core is certain, so as to achieve the purpose of determining the rotation angle of the valve core, thereby facilitating the adjustment of the flow area of the straight-through ball valve.

[0004] In the above patent, mainly by adding a spring, a push rod and a groove in the top of the ball valve, and by rotating the push rod into the corresponding groove, the straight-through ball valve can perform a stepped adjustment on the water flow. However, this way of adjusting the water flow will cause a strong impact and a large flow of water to directly impact the ball core inside the ball valve and make it rotate and shift when the ball valve rotates to a certain extent because a rotatable structure is installed above the straight-through ball valve. As a result, the water flow passing through the straight-through ball valve cannot flow according to the preset flow rate, reducing the use accuracy of the straight-through ball valve. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an adjustable straight-through ball valve to solve the above technical problems.

[0006] To achieve the above object, the present utility model is realized through the following technical solutions: An adjustable straight-through ball valve includes a valve body and flange plates.

The spring is located between the fixing plate and the valve shell. An insert is fixedly installed on the fixing plate at a position close to the straight groove. The pull ring controls the movement of the insert through the spring. When the user does not pull down the insert, the insert will be constantly pushed upward by the spring, greatly improving the integrity of the operation of the internal structure of the adjustable straight-through ball valve.

[0007] Furthermore, the adjustment assembly includes a rotary handle and a connecting shaft. The rotary handle and the connecting shaft are fixedly connected by bolts. A fixing block is fixedly installed on one side of the connecting shaft close to the rotary handle. A moving assembly is installed on one side of the fixing block away from the connecting shaft. A moving assembly is installed on one side of the fixing block away from the connecting shaft, so that when the rotary handle rotates, it can directly drive the moving assembly to rotate accordingly, improving the integrity of the movement of the internal structure of the adjustable straight-through ball valve.

[0008] Furthermore, a limiting strip is fixedly installed on one side of the fixing block away from the connecting shaft. A hollow rectangular block is installed on one side of the fixing block away from the connecting shaft. The limiting strip is located inside the hollow rectangular block. A first spring column is connected to the limiting strip on the side away from the fixing block and inside the hollow rectangular block.

A fixing shaft is fixedly installed on the side of the stabilizing block in the empty groove away from the telescopic member. A second spring column is fixedly installed between the fixing shaft and the telescopic member. The second spring column is used for the telescopic movement of the telescopic member. The second spring column is used for the telescopic movement of the telescopic member. The telescopic member can be telescopically adjusted by pressing and in cooperation with the second spring column, greatly improving the adaptability of the operation of the internal structure of the adjustable straight-through ball valve.

[0010] Furthermore, a sealing ring for the circulation seal of the ball valve is fixedly connected to one side of the flange away from the valve body. A sealing ring for the circulation seal of the ball valve is fixedly connected to one side of the flange away from the valve body, so that the adjustable through-ball valve can seal the connection during use, improving the safety of the adjustable through-ball valve during use.

[0011] Furthermore, the insert has the same shape as the straight groove. The insert having the same shape as the straight groove enables the insert to be completely inserted into the straight groove for fixation, improving the accuracy of controlling the fluid flow rate inside the adjustable through-ball valve.

[0012] Furthermore, the pull ring is in the shape of a square with rounded corners all around.

Detailed implementation mode

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0023] The following is combined with the attached Figure 1 - Attached Figure 6, a further detailed description of the present application is provided. An adjustable through-ball valve includes a valve body 1 and flange plates 2. The flange plates 2 are fixedly installed on both sides of the valve body 1. A flow-through hole 3 is penetrated and opened in the middle position of the valve body 1. The valve body 1 includes a valve housing 11, a fixing member 12, a sphere 13, an adaptation assembly 14, and an adjustment assembly 15. On one side of the sphere 13 away from the fixing member 12, a rotatable adjustment assembly 15 is fixedly installed. The adjustment assembly 15 rotates in cooperation with the adaptation assembly 14. On one side of the sphere 13 close to the fixing member 12, a plurality of straight grooves 124 are opened. The fixing member 12 includes a spring 121, a pull ring 122, and a fixing plate 123. The spring 121 is located between the fixing plate 123 and the valve housing 11. An insert 125 is fixedly installed at a position on the fixing plate 123 close to the straight groove 124. The pull ring 122 controls the movement of the insert 125 through the spring 121. The adjustment assembly 15 includes a turning handle 151 and a connecting shaft 153. The turning handle 151 and the connecting shaft 153 are fixedly connected by bolts. On one side of the connecting shaft 153 close to the turning handle 151, a fixing block 154 is fixedly installed. On one side of the fixing block 154 away from the connecting shaft 153, a moving assembly 152 is installed. On one side of the fixing block 154 away from the connecting shaft 153, a limiting strip 1524 is fixedly installed. On one side of the fixing block 154 away from the connecting shaft 153, a hollow rectangular block is installed. The limiting strip 1524 is located inside the hollow rectangular block. On the side of the limiting strip 1524 away from the fixing block 154 and inside the hollow rectangular block, a first spring column 1523 is connected. On the side of the first spring column 1523 away from the fixing block 154, a strip body 1522 is connected. On the side of the strip body 1522 away from the first spring column 1523, a convex block 1521 is fixedly installed. The adaptation assembly 14 includes a stabilizing block 141 and a telescopic member 144. The stabilizing block 141 is provided with an empty groove at the central position. On the side of the stabilizing block 141 in the empty groove away from the telescopic member 144, a fixing shaft 142 is fixedly installed. A second spring column 143 is fixedly installed between the fixing shaft 142 and the telescopic member 144. The second spring column 143 is used for the telescopic movement of the telescopic member 144. On the side of the flange plate 2 away from the valve body 1, a sealing ring 4 for the flow-through seal of the ball valve is fixedly connected. The shape of the insert 125 is the same as that of the straight groove 124, and the pull ring 122 is in the shape of a square with rounded corners on all four sides.

[0024] Among them, the installation intervals of the plurality of telescopic members 144 are the same as the opening intervals of the plurality of straight grooves 124, so that when the convex block 1521 enters between two different telescopic members 144, the insert 125 can be adaptively inserted into the corresponding straight groove 124 for fixation.

[0025] Among them, when the convex block 1521 touches the outer wall of the telescopic member 144 or the stabilizing block 141, the first spring column 1523 can contract in front of the fixing block 154 until the convex block 1521 enters between two different telescopic members 144 and then rebounds.

[0026] Wherein, a shaft body is fixedly connected above the pull ring 122, and the shaft body is fixed to the fixed disk 123. Moreover, the spring 121 is located between the valve housing 11 and the fixed disk 123, so that when the pull ring 122 is pulled downward, the fixed disk 123 can be directly driven to move downward.

[0027] Wherein, the sealing ring 4 is fixed when the flange 2 is connected to the external pipeline. When the flange 2 is completely connected to the external pipeline, the sealing ring 4 can directly prevent liquid leakage.

[0028] The working principle of the present utility model is described as follows: If the mechanical structures inside the adjustable straight-through ball valve are not clearly stated, they are all fixed by threads. In the figure, in order to more intuitively observe the professional technical features, the bolt connections are appropriately hidden. When the adjustable straight-through ball valve is in use, the user fixedly connects the adjustable straight-through ball valve to the external pipeline through the flange 2, and then the liquid flows through the flow hole 3. When the user needs to precisely control the liquid flow inside the adjustable straight-through ball valve, the pull ring 122 needs to be pulled downward first. At this time, the spring 121 cooperates with the fixed disk 123 to make the insert 125 leave the straight port groove 124. Then the user can rotate the turning handle 151. The rotated turning handle 151 will directly drive the fixed block 154, the convex block 1521, and the strip 1522 to rotate. During the rotation of the convex block 1521, it will touch the telescopic member 144. At this time, the extrusion of the convex block 1521 will cause the second spring column 143 to be compressed and make the telescopic member 144 contract inward. At the same time, the convex block 1521 will also contract inward through the first spring column 1523 when it is squeezed. Until the user rotates the convex block 1521 into the appropriate two telescopic members 144 according to the specific usage situation, the rotation of the turning handle 151 is stopped. At this time, the user releases the pull ring 122 with the hand, and the spring 121 will drive the fixed disk 123 to extend upward and make the insert 125 enter the corresponding straight port groove 124, thus completing the adjustment and fixation of the entire adjustable straight-through ball valve. So that when the adjustable straight-through ball valve is in use, regardless of the size of the water flow and the impact force inside the flow hole 3, the sphere 13 will not rotate, greatly improving the accuracy of controlling the water flow inside the adjustable straight-through ball valve.

[0029] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
