Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to an integrated multifunctional HVAC combination valve. Background Art

[0002] HVAC valves actually refer to valves used in HVAC systems. Traditional HVAC valves generally use ball valves, so they only have the function of opening and closing. During the operation of the HVAC system, gas will overflow. If the gas cannot be discharged in time, it will affect the circulation of water in the pipes in the HVAC system, and ultimately affect the heating effect. If the gas is exhausted through a ball valve, the user needs to pay attention to the pressure gauge at all times, and then actively exhaust the gas according to the pressure changes on the pressure gauge. If the gas cannot be exhausted automatically, it is extremely manpower-consuming. In addition, traditional HVAC valves only have a single water inlet joint and a water outlet joint. Even if the HVAC valve is connected to a diverter, it can only open all the diverter joints on the diverter or close all the diverter joints on the diverter at the same time. The water delivery mode is very single, and the HVAC system has multiple operating modes. Therefore, different pipes are often in different opening and closing states. If all the diverter joints on the diverter are opened or closed at the same time, the function of the HVAC system will be limited. Summary of the invention

[0024] The lower end of the right valve body 9 is provided with a sewage connection 47 which is connected with its internal space; the lower end of the sewage connection 47 is screwed with a lower valve body 48 which matches it; the lower valve body 48 is provided with a ball-type opening and closing component 49 which matches it; the left end of the ball-type opening and closing component 49 is provided with an opening and closing rod 50 which matches it; the left end of the opening and closing rod 50 passes through the lower valve body 48 to the left and is provided with a handle 51.

[0025] The lower end of the lower valve body 48 is threadedly connected with a quick connector 52 that matches the lower valve body 48 .

[0026] An annular locking step 53 is provided on the outer wall of the lower valve body 48; an elastic sleeve 56 is provided on the outer sleeve of the lower valve body 48, and the lower surface of the elastic sleeve 56 is in contact with the locking step 53; a connecting belt 54 is provided on the right outer wall of the elastic sleeve 56; a sealing cover 55 matching the lower end of the lower valve body 48 is provided on the right end of the connecting belt 54.

[0027] The method of using the utility model is as follows:

[0028] When using the HVAC combination valve of the present application, the left end of the water distribution pipe 7 can be connected to the pipeline of the HVAC system, and the quick connector below the lower valve body 48 can be connected to a hose or other pipeline for discharging sewage, so as to facilitate the transportation of sewage to the actually required location. At ordinary times, the lower valve body 48 can be closed by the ball-type opening and closing member 49. The ball-type opening and closing member 49 and the valve ball are actually the same existing opening and closing structures. The ball-type opening and closing member 49 has a through hole in the center. The lower valve body 48 can be closed by rotating the ball-type opening and closing member 49 so that the openings at both ends of the through hole are shielded and sealed by the inner wall of the lower valve body 48. When the ball-type opening and closing member 49 needs to be rotated, the opening and closing rod 50 can be rotated by the handle 51. At this time, the ball-type opening and closing member 49 will rotate, thereby changing the opening and closing state of the lower valve body 48.

[0029] When the water in the pipe of the HVAC system flows into the water distribution pipe, it will flow toward the water inlet joint 2 under the push of the subsequent water flow, and then flow into the water outlet joint 3 through the valve ball 4 in the middle valve body 1, and then flow into the exhaust chamber 13 of the exhaust body 12 through the left joint 10, the internal space of the right valve body 9, and the exhaust joint 11 in sequence. At this time, the water flow in the exhaust chamber 13 will gradually increase, and the floating block 19 has the characteristic of floating on water. As the floating block 19 floats up, the lower side wall of the notch 23 will push the guide rod 31 upward, thereby pressing the upper surface of the sealing block 30 tightly against the lower end surface of the exhaust nozzle 16, blocking and sealing the lower end of the exhaust nozzle 16, effectively preventing the water entering the exhaust chamber 13 from being discharged to the outside through the exhaust nozzle 16, thereby achieving a water leakage prevention effect.

[0030] When the HVAC system is running, gas will overflow, and the gas has the characteristic of ascending, and finally the gas will accumulate in the upper part of the exhaust chamber 13. As the gas accumulates more and more, the gas will squeeze the water flow in the exhaust chamber 13 downward, so that the water level in the exhaust chamber 13 drops, and the floating block 19 moves down accordingly. When the floating block 19 moves down, the seat plate 20 moves down accordingly under the action of gravity, and the sealing block 30 is no longer pressed against the lower end surface of the exhaust nozzle 16. At this time, the gas in the upper part of the exhaust chamber 13 can enter the exhaust nozzle 16 through the lower end of the exhaust nozzle 16. The gas then enters the gap between the upper end surface of the exhaust nozzle 16 and the upper inner wall of the protective cap 17 through the upper mouth of the exhaust nozzle 16. The gap between the upper end surface of the exhaust nozzle 16 and the upper inner wall of the protective cap 17 is connected with the air outlet 18. The gas will eventually be discharged to the outside through the air outlet 18. When the gas in the exhaust chamber 13 is discharged, the air pressure in the exhaust chamber 13 will return to normal. At this time, the water level in the exhaust chamber 13 returns to its original state, and the floating block 19 moves up and resets. The upper surface of the sealing block 30 blocks and seals the lower end mouth of the exhaust nozzle 16 again.

[0031] A plurality of water diversion joints 8 arranged on the rear side wall of the water diversion pipe 7 can be used to connect different pipes in the HVAC system, and each water diversion joint 8 has its own independent water diversion control device. When the corresponding water diversion joint 8 needs to be opened, the hand wheel 46 corresponding to the position of the water diversion joint 8 can be rotated, so that the rotating rod 42 moves upward along the threaded track of the inner wall of the screw hole 41. When the rotating rod 42 moves upward, the rubber sleeve 45 moves upward accordingly, and the rubber sleeve 45 no longer covers and seals the upper end of the water inlet hole 39. The water flow in the water diversion pipe 7 will flow into the pipeline connected to the water diversion joint 8 through the water inlet hole 39, the water diversion cavity 38, and the water diversion joint 8 in sequence for use.

[0032] In summary, the utility model can not only realize automatic exhaust of the HVAC system through the automatic exhaust device, effectively avoiding the situation where gas accumulation in the pipes of the HVAC system affects the heating effect, but also the automatic exhaust method does not require users to observe the barometer at all times, reducing manpower waste, and can exhaust the air at the first time, effectively ensuring the exhaust efficiency. At the same time, the water diversion control device can enable each water diversion joint 8 to be independently opened or closed according to actual needs, thereby being able to meet the different requirements of the HVAC system for its own pipeline status, and facilitating the realization of different functions of the HVAC system.

[0033] An annular limiting portion 33 is provided on the outer wall of the exhaust nozzle 16 located in the exhaust chamber 13, and a limiting sleeve 34 is provided outside the exhaust nozzle 16 between the upper surface of the limiting portion 33 and the upper inner wall of the upper cover 14. An elastic arm 35 is provided on the right side of the limiting sleeve 34. The right end of the elastic arm 35 is bent downward and located above the seat plate 20. The existence of the elastic arm 35 can limit the seat plate 20 from moving upward too much when the seat plate 20 moves upward, thereby preventing the exhaust nozzle 16 from excessively squeezing the opening and closing block downward to cause excessive compression of the spring 32, and avoiding the spring 32 from being overly compressed and causing elastic failure. Therefore, the elastic arm 35 has the effect of protecting the spring 32.

[0034] A noise reduction sponge 36 is provided between the upper inner wall of the protective cap 17 and the upper end surface of the exhaust nozzle 16. When the gas in the exhaust nozzle 16 is discharged to the outside through the air outlet 18, it will inevitably pass through the noise reduction sponge 36. The noise reduction sponge 36 is breathable and can effectively absorb the noise generated during exhaust, thereby achieving a noise reduction effect.

[0035] A drain joint 47 which is in communication with the internal space thereof is provided at the lower end of the right valve body 9, a lower valve body 48 which is matched therewith is screwed on the lower end of the drain joint 47, a ball-type opening and closing component 49 which is matched therewith is provided in the lower valve body 48, an opening and closing rod 50 which is matched therewith is provided at the left end of the ball-type opening and closing component 49, and a handle 51 is provided at the left end of the opening and closing rod 50. In order to ensure the heating effect of the HVAC system, it is sometimes necessary to clean the pipes of the HVAC system. When the pipes are cleaned, sewage will be generated, which can be discharged to the outside through the quick connector 52 of the lower valve body 48.

[0036] An annular locking step 53 is provided on the outer wall of the lower valve body 48, and an elastic sleeve 56 is coated on the outer sleeve of the lower valve body 48. The lower surface of the elastic sleeve 56 fits with the locking step 53. A connecting belt 54 is provided on the right outer wall of the elastic sleeve 56. A sealing cover 55 matching the lower end of the lower valve body 48 is provided on the right end of the connecting belt 54. When there is no need to drain sewage, the quick connector 52 can be removed from the lower end of the lower valve body 48, and then the sealing cover 55 can be tightened to the outside of the lower end of the lower valve body 48, so as to seal the lower end port of the lower valve body 48 and prevent dust from entering the lower valve body 48.
