Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning (HVAC) equipment, and in particular to a novel HVAC valve. Background Technology

[0002] HVAC valves play a crucial role in HVAC systems, primarily used to control and regulate fluid flow and pressure in heating and air conditioning systems. This facilitates property management and allows residents to independently adjust the temperature and duration of heating. By controlling fluid flow and pressure, valves achieve multiple functions such as temperature regulation, energy saving, and on / off control.

[0003] While existing HVAC valves can regulate temperature, the presence of large particles such as silt and rust in the water leads to the accumulation of scale and rust over time, shortening the lifespan of the equipment and hindering internal filtration and cleaning. Therefore, those skilled in the art have proposed a novel HVAC valve to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a new type of HVAC valve for HVAC equipment. Through the filter element, it filters impurities, intercepts large particles, reduces scale formation, and effectively reduces the generation of rust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel HVAC valve for HVAC equipment, comprising a first connecting pipe, a filter outlet pipe threadedly connected to the front end of the first connecting pipe, a filter pipe fixedly connected to the center of the front end of the filter outlet pipe, a filter inlet pipe fixedly connected to the center of the front end face of the filter pipe, a drain pipe threadedly connected to the lower end face of the filter pipe, a filter element provided inside the filter pipe, a drain pipe provided at the center of the upper end face of the drain pipe, and a drain plug provided at the output end of the drain pipe; With the above technical solution, water flows in from the third connecting pipe during use. Since the third connecting pipe is connected to the filter inlet pipe by the first pipe thread, the water smoothly enters the filter inlet pipe. Then the water enters the filter pipe, and the filter element in the filter pipe will filter the impurities in the water. The filtered water flows out from the filter outlet pipe, which is connected to the front end of the first connecting pipe by a thread, so that the filtered water enters the first connecting pipe. As usage time increases, impurities filtered by the filter element will accumulate. When sewage needs to be discharged, open the drain plug at the lower end of the drain pipe, and the sewage will be discharged through the drain pipe. The drain pipe is threadedly connected to the lower end of the filter tube, facilitating sewage discharge. When the filter element needs to be replaced, close the main valve. Because the drain pipe is threadedly connected to the filter tube, the drain pipe can be unscrewed to remove it. At this time, the filter element inside the filter tube can be replaced. The filter element simultaneously filters impurities, intercepts large particles, protects pipes and equipment, reduces scale formation, extends equipment lifespan, facilitates cleaning, and effectively reduces the formation of rust.

[0006] Furthermore, protective baffles are provided symmetrically about the center of the first connecting pipe on both outer side walls, and a gate is provided at the center of the first connecting pipe, with a control and adjustment device provided on the upper end face of the gate. Through the above technical solution, the gate and control device in the first connecting pipe can regulate the water flow rate, and the two protective baffles are used to protect the equipment and also serve as heat preservation.

[0007] Furthermore, the control and adjustment device includes a first connecting shaft, which penetrates the upper inner wall of the first connecting pipe and is fixedly connected to the upper surface of the gate plate. A protrusion is fixedly connected to the center of the upper surface of the first connecting shaft. A lock cylinder is provided inside the first connecting shaft and the protrusion. A lock hole is provided at the upper end of the lock cylinder. Lock bolts are provided at the front and rear ends of the lower end of the outer wall of the lock cylinder. The two lock bolts respectively lead to the front and rear ends of the interior between the two protective baffles. A fastening groove is engaged at the upper end of the protrusion. A second connecting shaft is fixedly connected to the center of the upper surface of the fastening groove. A HVAC valve handwheel is fixedly connected to the upper surface of the protrusion. Through the above technical solution, the control and adjustment device has a safety locking function. By pulling out the HVAC valve handwheel, the locking groove and the second connecting shaft can be brought out. At this time, the lock hole inside the protrusion is exposed. Inserting a specific key into the upper lock hole inside the lock cylinder can control the bolts at the front and rear of the lower end of the outer wall of the lock cylinder. The two bolts lead to the front and rear of the two protective baffles respectively. The two protective baffles are used to protect the equipment and also play a role in heat preservation. When the bolts are extended, the gate is locked and the flow rate cannot be adjusted by rotating the HVAC valve handwheel, thus playing a safety protection role. The gate in the first connecting pipe can regulate the water flow rate. The first connecting shaft in the control and regulating device passes through the inner wall of the first connecting pipe and is fixedly connected to the upper surface of the gate. When the HVAC valve handwheel is turned, since the protrusion is fixedly connected to the first connecting shaft, and the upper end of the protrusion is engaged with a fastening groove, which is fixedly connected to the second connecting shaft, this will drive the first connecting shaft to rotate, thereby causing the gate to rotate in the first connecting pipe, thus realizing the regulation of the water flow rate in the first connecting pipe.

[0008] Furthermore, a second pipe thread is provided at the rear end of the outer side wall of the first connecting pipe, a second flange is fitted on the rear end of the outer side wall of the first connecting pipe, and a second rubber gasket is provided on the rear end face of the second flange. Through the above technical solution, the second pipe thread at the rear end of the outer wall of the first connecting pipe can be threaded to other pipes, or it can be connected through the second flange. The second rubber gasket behind it can play a sealing role to prevent water leakage.

[0009] Furthermore, the internal thread of the filter water inlet pipe is connected to a third connecting pipe, the front end of the outer side wall of the third connecting pipe is provided with a first pipe thread, the outer side wall of the third connecting pipe is fitted with a first flange near the front end, and the front end face of the first flange is provided with a first rubber gasket. Through the above technical solution, the internal thread of the filter water inlet pipe is connected to a third connecting pipe. The first pipe thread at the front end of the outer wall of the third connecting pipe is used to connect with other pipes, or it can be connected through the first flange. The first rubber gasket on its front end achieves the sealing function.

[0010] Furthermore, a threaded hole is provided between the two protective baffles; The above technical solution provides threaded holes between the two protective baffles for easy assembly and disassembly.

[0011] This utility model has the following beneficial effects: In this invention, the filter element plays a filtering role, which can intercept large particles of impurities such as mud, sand and rust, protect pipes and equipment, reduce scale formation, extend equipment service life, facilitate cleaning, and effectively reduce the generation of rust.

[0012] In this invention, the locking bolts at the front and rear of the lower end of the outer wall of the lock cylinder can be controlled. The two locking bolts lead to the front and rear of the interior between the two protective baffles, respectively. The two protective baffles are used to protect the equipment and also serve as heat preservation.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1-4 An embodiment of this utility model provides a novel HVAC valve, comprising a first connecting pipe 1, a filter outlet pipe 17 threadedly connected to the front end of the first connecting pipe 1, a filter pipe 7 fixedly connected to the center of the front end of the filter outlet pipe 17, a filter inlet pipe 16 fixedly connected to the center of the front end face of the filter pipe 7, a drain pipe 8 threadedly connected to the lower end face of the filter pipe 7, a filter element 10 provided inside the filter pipe 7, a drain pipe 12 provided at the center of the upper end face of the drain pipe 8, and a drain plug 11 provided at the output end of the drain pipe 12.

[0017] During use, water flows in through the third connecting pipe 18. Since the third connecting pipe 18 is threadedly connected to the filter inlet pipe 16 through the first pipe thread 3, the water smoothly enters the filter inlet pipe 16. Then the water enters the filter pipe 7, where the filter element 10 filters the impurities in the water. The filtered water flows out through the filter outlet pipe 17, which is threadedly connected to the front end of the first connecting pipe 1, thus allowing the filtered water to enter the first connecting pipe 1.

[0018] As usage time increases, impurities filtered by filter element 10 will accumulate. When sewage needs to be discharged, open the drain plug 11 at the output end of drain pipe 12 at the lower end of drain pipe 8, and sewage will be discharged through drain pipe 12. Drain pipe 8 is threadedly connected to the lower end face of filter pipe 7, facilitating sewage discharge. When filter element 10 needs to be replaced, close the main valve. Because drain pipe 8 is threadedly connected to filter pipe 7, drain pipe 8 can be unscrewed to remove it. At this time, filter element 10 inside filter pipe 7 can be replaced. Filter element 10 simultaneously filters impurities, intercepts large particles, protects pipes and equipment, reduces scale formation, extends equipment lifespan, facilitates cleaning, and effectively reduces the formation of rust.

[0019] The two outer side walls of the first connecting pipe 1 are symmetrically provided with protective baffles 9 about the center of the first connecting pipe 1. A gate 2 is provided at the center of the inside of the first connecting pipe 1. A control and adjustment device 4 is provided on the upper end face of the gate 2.

[0020] The gate 2 and control and regulating device 4 in the first connecting pipe 1 can regulate the water flow rate, and the two protective baffles 9 are used to protect the equipment and also serve as heat preservation.

[0021] The control and adjustment device 4 includes a first connecting shaft 408, which passes through the upper inner wall of the first connecting pipe 1 and is fixedly connected to the upper end face of the gate 2. A protrusion 402 is fixedly connected to the center of the upper end face of the first connecting shaft 408. A lock cylinder 403 is provided inside the first connecting shaft 408 and the protrusion 402. A lock hole 405 is provided at the upper end of the lock cylinder 403. Lock bolts 404 are provided at the front and rear ends of the lower end of the outer wall of the lock cylinder 403. The two lock bolts 404 lead to the front end and rear end of the interior between the two protective baffles 9, respectively. A fastening groove 407 is engaged at the upper end of the protrusion 402. A second connecting shaft 401 is fixedly connected to the center of the upper end face of the fastening groove 407. A heating and ventilation valve handwheel 406 is fixedly connected to the upper end face of the protrusion 402.

[0022] The first connecting shaft 408 in the control and adjustment device 4 passes through the inner wall of the first connecting pipe 1 and is fixedly connected to the upper end face of the gate 2. When the HVAC valve handwheel 406 is rotated, since the protrusion 402 is fixedly connected to the first connecting shaft 408, and the upper end of the protrusion 402 is engaged with the engagement groove 407, which is fixedly connected to the second connecting shaft 401, this will drive the first connecting shaft 408 to rotate, thereby causing the gate 2 to rotate inside the first connecting pipe 1, thereby realizing the adjustment of the water flow rate inside the first connecting pipe 1.

[0023] The control and adjustment device 4 has a safety locking function. By pulling out the HVAC valve handwheel 406, the locking groove 407 and the second connecting shaft 401 can be brought out. At this time, the lock hole 405 inside the protrusion 402 is exposed. Inserting a specific key into the upper lock hole 405 inside the lock cylinder 403 can control the bolts 404 at the front and rear of the lower end of the outer wall of the lock cylinder 403. The two bolts 404 lead to the front and rear of the interior between the two protective baffles 9, respectively. The two protective baffles 9 are used to protect the equipment and also serve as heat preservation. When the bolts 404 are extended, the gate 2 is locked, and the flow rate cannot be adjusted by rotating the HVAC valve handwheel 406, thus providing a safety protection function.

[0024] like Figure 1 , 2 As shown in Figure 3, the outer side wall of the first connecting pipe 1 is provided with a second pipe thread 14 at the rear end. The outer side wall of the first connecting pipe 1 is fitted with a second flange 15 near the rear end. The rear end face of the second flange 15 is provided with a second rubber gasket 13. The second pipe thread 14 at the rear end of the outer side wall of the first connecting pipe 1 can be threaded to other pipes or connected through the second flange 15. The second rubber gasket 13 behind it can play a sealing role to prevent water leakage.

[0025] The internal thread of the filter water inlet pipe 16 is connected to a third connecting pipe 18. The front end of the outer wall of the third connecting pipe 18 is provided with a first pipe thread 3. The front end of the outer wall of the third connecting pipe 18 is fitted with a first flange 6. The front end face of the first flange 6 is provided with a first rubber gasket 5. The internal thread of the filter water inlet pipe 16 is connected to the third connecting pipe 18. The first pipe thread 3 at the front end of the outer wall of the third connecting pipe 18 is used to connect with other pipes, or it can be connected through the first flange 6. The first rubber gasket 5 at its front end face provides a sealing function.

[0026] A threaded hole is provided between the two protective baffles 9 to facilitate assembly and disassembly.

[0027] Working principle: When in use, water flows in from the third connecting pipe 18. Since the third connecting pipe 18 is threadedly connected to the filter inlet pipe 16 through the first pipe thread 3, the water smoothly enters the filter inlet pipe 16. Then the water enters the filter pipe 7. The filter element 10 in the filter pipe 7 will filter the impurities in the water. The filtered water flows out from the filter outlet pipe 17. The filter outlet pipe 17 is threadedly connected to the front end of the first connecting pipe 1, so that the filtered water enters the first connecting pipe 1.

[0028] As usage time increases, impurities filtered by filter element 10 will accumulate. When sewage needs to be discharged, open the drain plug 11 at the output end of drain pipe 12 at the lower end of drain pipe 8, and sewage will be discharged through drain pipe 12. Drain pipe 8 is threadedly connected to the lower end face of filter pipe 7, facilitating sewage discharge. When filter element 10 needs to be replaced, close the main valve. Because drain pipe 8 is threadedly connected to filter pipe 7, drain pipe 8 can be unscrewed to remove it. At this time, filter element 10 inside filter pipe 7 can be replaced. Filter element 10 plays the role of filtering impurities, intercepting large particles such as mud, sand, and rust, protecting pipes and equipment, reducing scale formation, extending equipment life, facilitating cleaning, and effectively reducing the generation of rust.

[0029] The gate 2 inside the first connecting pipe 1 can adjust the water flow rate. The first connecting shaft 408 in the control and adjustment device 4 passes through the inner wall of the first connecting pipe 1 and is fixedly connected to the upper end face of the gate 2. When the HVAC valve handwheel 406 is rotated, since the protrusion 402 is fixedly connected to the first connecting shaft 408, and the upper end of the protrusion 402 is engaged with a fastening groove 407, which is fixedly connected to the second connecting shaft 401, this will drive the first connecting shaft 408 to rotate, thereby causing the gate 2 to move up and down inside the first connecting pipe 1, so as to adjust the water flow rate inside the first connecting pipe 1.

[0030] The control and adjustment device 4 has a safety locking function. By pulling out the HVAC valve handwheel 406, the locking groove 407 and the second connecting shaft 401 can be brought out. At this time, the lock hole 405 inside the protrusion 402 is exposed. Inserting a specific key into the upper lock hole 405 inside the lock cylinder 403 can control the bolts 404 at the front and rear of the lower end of the outer wall of the lock cylinder 403. The two bolts 404 lead to the front and rear of the interior between the two protective baffles 9, respectively. The two protective baffles 9 are used to protect the equipment and also serve as heat preservation. When the bolts 404 are extended, the gate 2 is locked, and the flow rate cannot be adjusted by rotating the HVAC valve handwheel 406, thus providing a safety protection function. A threaded hole is provided between the two protective baffles 9 for easy assembly and disassembly.

[0031] The second pipe thread 14 at the rear end of the outer wall of the first connecting pipe 1 can be threaded to other pipes or connected through the second flange 15. The second rubber gasket 13 behind it can play a sealing role to prevent water leakage. Similarly, the first pipe thread 3 at the front end of the outer wall of the third connecting pipe 18 is used to connect to other pipes or connected through the first flange 6. The first rubber gasket 5 at its front end achieves the sealing function.

[0032] When the lock cylinder is turned, it drives the bolt to move through components such as the lock cylinder dial and the moving block. When the key is rotated clockwise, the lock cylinder dial pushes the moving block. The stop groove on the moving block cooperates with the pin on the bolt plate, causing the bolt plate to move horizontally, thereby allowing the bolt to extend and locking. This is a commonly used technique in existing locking technology, and will not be elaborated on further here.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
