Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning (HVAC) valves, and more particularly to an HVAC valve for HVAC equipment. Background Technology

[0002] HVAC control valves, also known as shut-off valves and valves for residential heating, facilitate property management and allow residents to independently adjust the temperature and time of heating. They are environmentally friendly and energy-saving products. HVAC valves are usually composed of an electric actuator and a valve body, and after installation and commissioning, they become HVAC control valves.

[0003] The valve uses electrical energy as a power source to connect the electric actuator to drive the valve, realize the valve opening and closing and regulating actions, thereby achieving the purpose of opening or regulating the pipeline medium.

[0004] However, existing HVAC valves are exposed and are prone to damage after a period of use, which can easily lead to heating leaks and insufficient safety performance. Therefore, protective devices are needed. In addition, the lack of positioning support devices during the installation of HVAC valves makes the interface between the heating pipes and the valves prone to loosening. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment of an HVAC valve, including a support base 1 and a valve body 5. A lifting base 2 is movably connected to the support base 1. A rack 8 is provided on the outer side of the lifting base 2, and a transmission component is provided at one end of the rack 8. The transmission component connects the support base 1 and the lifting base 2. The valve body 5 is located at the top of the lifting base 2, and a protective component is provided on the outer side of the valve body 5. The protective component connects the lifting base 2 and the valve body 5. The transmission component includes a fixed seat 15, with a knob 9 rotatably connected to the outer end of the fixed seat 15. A transmission gear 12 is provided at one end of the knob 9, and one end of the transmission gear 12 extends to the outer side of the rack 8. The transmission gear 12 meshes with the rack 8. When the knob 9 rotates, the knob 9, in conjunction with the transmission gear 12, transmits power to the lifting base 2, causing the lifting base 2 to rise and fall inside the support base 1. The protective component includes a protective shell A3 and a protective shell B4. Connecting blocks A are provided on both sides of the top of the protective shell A3. 6. Connecting blocks B7 are provided on both sides of the top of the protective housing B4. When the protective housing A3 and the protective housing B4 are connected, the connecting blocks B7 are inserted into the inside of the connecting block A6. Before the valve body 5 is installed, the knob 9 is rotated. The knob 9, in conjunction with the transmission gear 12 and the rack 8 on the outside of the lifting base 2, allows the operator to position the lifting base 2 according to the installation position. When the knob 9 is rotated to a certain angle, one end of the spring block 10 on the outside of the fixing seat 15 is inserted into the inside of the slot 11, thereby limiting the knob 9. Then, the valve body 5 is placed into the protective housing A3 at the top of the lifting base 2, and then the protective housing B4 is connected to the protective housing A3. The valve body 5 is protected by the protective housing B4 and the protective housing A3. When the connecting block A6 is connected to the connecting block B7, one end of the limiting block 13 on both sides of the top of the connecting block B7 is inserted into the inside of the connecting block A6. The protective housing B4 and the protective housing A3 can be quickly disassembled and assembled by pressing the limiting block 13.

[0025] Please see Figures 2-3 In this embodiment, bolt holes are provided on the top surface of the support base 1 and the bottom end of the lifting base 2. The support base 1 and the lifting base 2 can be fixedly connected to the ground and the wall by bolts. The top of the support base 1 is provided with a lifting groove, and the bottom end of the lifting base 2 extends to the inside of the lifting groove. The lifting base 2 is movably connected to the support base 1 through the lifting groove.

[0026] Please see Figures 4-5In this embodiment, the support base 1 and the fixed base 15 are an integral structure. Spring blocks 10 are movably connected to both sides of the fixed base 15. A slot 11 is provided on the outer side of the knob 9. When the knob 9 is rotated to a certain angle, one end of the spring block 10 is inserted into the inner side of the slot 11. A spring connector is provided on the inner side of the fixed base 15 at the rear end of the spring block 10. The spring block 10 is movably connected to the fixed base 15 through the spring connector. The lifting base 2 and the protective shell A3 are an integral structure. A limit groove is provided on the inner wall of the connecting block A6. Limit blocks 13 are provided on both sides of the top of the connecting block B7. When the connecting block A6 is connected to the connecting block B7, one end of the limit block 13 is inserted into the inner side of the limit groove. A connecting spring 14 is provided on the inner side of the connecting block B7 at the rear end of the limit block 13. The limit block 13 is movably connected to the connecting block B7 through the connecting spring 14.

[0027] During operation, by rotating knob 9, the operator can position the lifting base 2 according to the installation position by engaging the transmission gear 12 and the rack 8 on the outer side of the lifting base 2. When knob 9 is rotated to a certain angle, one end of the spring block 10 on the outer side of the fixed base 15 is inserted into the inner side of the slot 11, thereby limiting the knob 9. Then, bolts can be used to fix the support base 1 and the lifting base 2 to the ground and the wall. Subsequently, the valve body 5 is placed into the protective shell A3 at the top of the lifting base 2, and then the protective shell B4 is connected to the protective shell A3, thereby protecting the valve body 5 through the protective shell B4 and the protective shell A3. When the connecting block A6 is connected to the connecting block B7, one end of the limiting block 13 on both sides of the top of the connecting block B7 is inserted into the inner side of the connecting block A6, so that the protective shell B4 and the protective shell A3 can be quickly disassembled and assembled by pressing the limiting block 13.

[0028] Through the above steps, by rotating knob 9, which, in conjunction with transmission gear 12 and rack 8 on the outside of lifting base 2, allows the operator to position lifting base 2 according to the installation position, facilitating subsequent installation of valve body 5. Valve body 5 is protected by protective shells B4 and A3, and protective shells B4 and A3 can be quickly disassembled and assembled by pressing limit block 13. This addresses the problem that existing HVAC valves are exposed and easily damaged after a period of use, leading to heating leaks and insufficient safety performance. Therefore, protective devices are needed. Furthermore, the lack of positioning support devices during HVAC valve installation makes the interface between heating pipes and HVAC valves prone to loosening.
