Description

Technical Field

[0001] This utility model relates to the field of ceramic ball valve technology, and in particular to the valve stem of an adjustable flow ceramic ball valve. Background Technology

[0002] Ceramic materials exhibit very low deformation and possess significantly higher bonding strength than metals. Generally, the crystal ions composing ceramic materials have small ionic radii, high ionic valence, and large coordination numbers. These properties determine that ceramic materials possess very high tensile strength, compressive strength, elastic modulus, and hardness. However, the inherent brittleness and difficulty in processing ceramics have limited their applications. In the past decade or so, the development and progress of martensitic transformation toughening technology, composite materials technology, and the concept of nanoceramics have greatly improved the brittleness of ceramics, significantly enhancing their toughness and strength, and continuously expanding their application range. The application of new ceramic materials in the petroleum, chemical, and machinery industries is very active. Utilizing the wear resistance and corrosion resistance of ceramics to manufacture wear-resistant and corrosion-resistant parts to replace metal materials is one of the important development directions in the high-tech materials market in recent years.

[0003] Currently used ceramic ball valves regulate flow by adjusting the valve disc angle by rotating the valve stem. However, they lack valve stem fixation. In environments with high water pressure or where the water contains media, the valve disc is easily displaced by the water flow or media, leading to changes in flow rate and a decrease in the control accuracy of the fluid system. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable flow ceramic ball valve stem, which aims to improve the problem that the valve disc is easily deflected by force in environments with high water pressure or water containing media, resulting in a decrease in the control accuracy of the fluid system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flow ceramic ball valve stem, including a valve seat, with an inlet pipe and an outlet pipe respectively at both ends of the valve seat, and a filter mechanism for filtering impurities in the water flow is provided at the position of the inlet pipe of the valve seat, a valve disc is rotatably installed inside the valve seat via the valve stem, a rod handle is fixed at the top of the valve stem, and an adjusting handle is slidably provided on the outer surface of the valve stem, the adjusting handle is connected to the rod handle through an elastic element, and a locking mechanism is provided on the adjusting handle for locking and fixing the rod handle.

[0006] Preferably, the locking mechanism includes an upper locking member fixedly installed on the adjusting handle, and a lower locking member that engages with the lower locking member is fixed on the outer surface of the valve seat.

[0007] Preferably, both the upper and lower clamping members are provided with a plurality of meshing teeth.

[0008] Preferably, the elastic element includes a spring sleeved on the surface of the valve stem, with both ends of the spring fixedly mounted on the stem handle and the adjusting handle, respectively.

[0009] Preferably, a limiting rod is slidably provided between the rod handle and the adjusting handle, and both ends of the limiting rod are provided with limiting protrusions.

[0010] Preferably, a mounting bracket is installed at the water inlet pipe of the valve disc, and a funnel with a side opening is provided on the mounting bracket for sealing and sliding.

[0011] Preferably, the valve disc has a guide block inside its inlet pipe, with the top of the guide block facing the bottom of the funnel's side opening.

[0012] Preferably, both the mounting bracket and the funnel are equipped with magnetic blocks for use in conjunction.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting up a rod handle, an adjusting handle and a locking mechanism, the locking mechanism can adjust the angle position of the rod handle and the adjusting handle, and at the same time lock and fix the rod handle and the adjusting handle to prevent the valve disc from shifting due to water pressure, which would affect the accuracy of the flow rate.

[0015] 2. In this utility model, by setting up a filtration mechanism, the solid particles inside the water flow or the welding slag and rust washed away in the pipe are filtered and isolated, so as to avoid these impurities accumulating at the throttling port, causing valve disc blockage and affecting the use of the valve disc.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of an adjustable flow ceramic ball valve stem, including a valve seat 1. The valve seat 1 has an inlet pipe and an outlet pipe at both ends, and a filter mechanism for filtering impurities in the water flow is provided at the inlet pipe position. A valve disc 3 is rotatably mounted inside the valve seat 1 via a valve stem 2. A stem handle 4 is fixed to the top of the valve stem 2, and an adjusting handle 5 is slidably provided on the outer surface of the valve stem 2. The adjusting handle 5 is connected to the stem handle 4 via an elastic element, and a lock is provided on the adjusting handle 5 for locking and fixing the stem handle 4. The valve is equipped with a filtration mechanism to filter and isolate solid particles inside the water flow or welding slag and rust washed away from the pipes. This prevents these impurities from accumulating at the throttling orifice, which could clog the valve disc 3 and affect its operation. The valve also features a lever handle 4, an adjusting handle 5, and a locking mechanism. The locking mechanism allows for adjustment of the angles of the lever handle 4 and the adjusting handle 5, while simultaneously locking and fixing them in place to prevent the valve disc 3 from shifting due to water pressure, thus ensuring accurate flow rate.

[0024] Reference Figure 1 and Figure 4 The locking mechanism includes an upper locking member 7 fixedly installed on the adjusting handle 5, and a lower locking member 8 fixed on the outer surface of the valve seat 1 for engaging with the lower locking member 8. By setting the upper locking member 7 and the lower locking member 8, the locking and fixing of the rod handle 4 and the adjusting handle 5 can be achieved by utilizing the cooperation between the upper locking member 7 and the lower locking member 8.

[0025] Reference Figure 1 and Figure 4 Both the upper clamp 7 and the lower clamp 8 are provided with several meshing teeth. By setting the teeth on the upper clamp 7 and the lower clamp 8 to mesh with each other, the position of the rod handle 4 and the adjustment handle 5 can be effectively fixed. At the same time, depending on the number of teeth, different flow rate adjustments can be made to meet different usage needs.

[0026] Reference Figure 4 The elastic element includes a spring 6 sleeved on the surface of the valve stem 2. The two ends of the spring 6 are respectively fixedly installed on the stem handle 4 and the adjusting handle 5. By setting the spring 6, the elasticity of the spring 6 drives the adjusting handle 5 to move downward, applying downward pressure to the adjusting handle 5 to ensure that the upper clamp 7 and the lower clamp 8 can be stably engaged, avoiding the problem of the upper clamp 7 shaking and dislodging due to vibration during use.

[0027] Reference Figures 1-3 A limiting rod 13 is slidably provided between the rod handle 4 and the adjusting handle 5, and both ends of the limiting rod 13 are provided with limiting protrusions. By setting the limiting rod 13, the limiting rod 13 is used to limit and guide the rod handle 4 and the adjusting handle 5, so as to ensure that the adjusting handle 5 can simultaneously limit the rod handle 4 while sliding up and down.

[0028] Reference Figure 2 A mounting bracket 10 is installed at the water inlet pipe of valve disc 3. A funnel 12 with a side opening is provided on the mounting bracket 10. By setting the funnel 12, solid particles inside the water flow or welding slag and rust washed away in the pipe are filtered and isolated, so as to avoid these impurities accumulating at the throttling port, causing valve disc 3 to be blocked and affecting the use of valve disc 3. The use of funnel 12 for filtration also facilitates the subsequent cleaning of impurities.

[0029] Reference Figure 2 The valve disc 3 has a guide block 9 inside its inlet pipe. The top of the guide block 9 is directly opposite the bottom of the side opening of the funnel 12. By setting the guide block 9, the water flow can be guided so that the water flows into the filter funnel and then enters the valve body after being filtered by the funnel 12, thus achieving the filtration work.

[0030] Reference Figure 2 Both the mounting bracket 10 and the funnel 12 are equipped with magnetic blocks 11 for use. The magnetic blocks 11 can further fix the funnel 12, improve the fixing effect, prevent the funnel 12 from shaking or shifting, and improve the stability of the funnel 12 installation.

[0031] Working principle: Hold both the lever handle 4 and the adjusting handle 5 simultaneously, so that the adjusting handle 5 is in contact with the lever handle 4. The lever handle 4 moves upward, causing the upper locking piece 7 to disengage from the lower locking piece 8, thus releasing the fixation of the lever handle 4 and the adjusting handle 5. Rotate the lever handle 4 and the adjusting handle 5, so that the lever handle 4 drives the valve stem 2 to rotate. The rotation of the valve stem 2 drives the valve disc 3 to rotate synchronously. Different rotation angles of the valve disc 3 can achieve the adjustment of different flow rates.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
