Description

Technical Field

[0001] The utility model belongs to the technical field of HVAC equipment, and in particular relates to a HVAC valve of HVAC equipment. Background Art

[0002] Traditional HVAC control valves are favored by the market for their high reliability and low power consumption. These valves typically use hours as the unit of measurement for both timekeeping and purchase quantity. Energy-saving valves, with purchase quantity information stored on the user's card, activate each time the card is swiped, precisely controlling heating consumption. Conventional valves, on the other hand, open the first time a user swipes their card after purchasing heating, but remain stationary for subsequent swipes, displaying only basic information.

[0003] In practice, HVAC valves, when opened and closed, can cause vibrations in the water inlet and outlet pipes. This vibration is primarily caused by the transient pressure changes generated when the valve is rapidly opened or closed. Over time, this vibration can damage the HVAC valve's internal structure (such as structural damage or leakage). For example, patent application number 202020159391.2 lacks a buffer structure, resulting in poor safety performance.

[0004] Therefore, it is necessary to design a HVAC valve for HVAC equipment to solve the above technical problems. Summary of the Invention

[0005] In order to solve the above technical problems, the utility model proposes a HVAC valve for HVAC equipment, which adopts the design of a shock-absorbing mechanism to effectively reduce the pipe shaking caused by instantaneous pressure changes when the HVAC valve body is opened or closed. This design can absorb the energy generated by the pipe shaking through the arc-shaped clamping plate and the arc-shaped shock-absorbing pad, thereby reducing damage to the internal structure of the HVAC valve body and improving the service life and safety of the HVAC valve.
