Description

Exhaust valve for floor heating water separator

Technical Field

The utility model belongs to the technical field of water heating accessories, and particularly relates to an exhaust valve for a floor heating water separator.

Background

In a water heating type floor heating system, a floor heating water separator is a very important component part, is generally arranged near a boiler and comprises a water inlet main pipe, a water return main pipe and a plurality of branch pipes, and is connected with buried pipelines in different areas through different branch pipes. The floor heating water separator is said to be a hub of the floor heating system. Therefore, the floor heating water separator is required to be provided with an exhaust valve so as to regularly exhaust the gas in the pipeline system, thereby reducing the hidden danger of water leakage. As chinese patent CN212657270U discloses an exhaust valve structure for floor heating water knockout drum, including the disk seat that has sealed chamber, the disk seat on rotate and be connected with the roating seat, the inner wall of roating seat and the outer wall of disk seat between be provided with the exhaust clearance, the disk seat on be provided with the exhaust hole in intercommunication sealed chamber and exhaust clearance, the exhaust hole passes through the exhaust passage intercommunication external world.

The disadvantage of the prior art is that the position and direction of the exhaust channel are fixed, and if other objects are arranged in the area opposite to the exhaust channel when the floor heating water separator is installed, the exhaust is inevitably affected.

Disclosure of Invention

The utility model aims to provide an exhaust valve for floor heating water knockout drum, which is more flexible to arrange.

For this purpose, the utility model adopts the following technical scheme: the exhaust valve for the floor heating water separator comprises a valve seat, a plug and a valve seat, wherein the valve seat is communicated with a pipeline system; the method is characterized in that: an exhaust port seat is arranged outside the valve seat and is provided with an exhaust port communicated with the outside; the inner wall of the exhaust port seat is provided with at least one circumferential annular groove or ridge, the outer wall of the valve seat is provided with at least one circumferential annular ridge or groove, and the exhaust port seat is rotationally connected with the valve seat through the matching of the annular ridge and the groove. At least one through hole is arranged on the valve seat wall, so that the inner cavity of the valve seat is communicated with the exhaust port seat.

Further, the exhaust port is axially positioned between the annular groove or rib of the exhaust port seat and the valve seat and the passage of the piping system.

And at least two sealing rings are axially arranged in the region where the port of the valve seat is matched with the plug.

The utility model has the exhaust seat outside the valve seat, and the exhaust seat is connected with the valve seat through the annular groove edge, so 360 degrees of operation can be performed ⁰ Can rotate the exhaust portIn either direction. When the plug is screwed tightly matched with the valve seat, a passage between the valve seat and the pipeline system is blocked, and the whole exhaust valve is closed at the moment; when the plug is unscrewed, the gas in the pipe system can reach the valve seat through the gap. Two sealing rings are arranged between the valve seat and the plug, so that even if the plug is unscrewed from a part, at least one sealing ring is arranged between the plug and the valve seat to prevent gas from escaping from the sealing ring; and the annular prismatic groove between the valve seat and the exhaust port seat also prevents gas from escaping from the space between the valve seat and the exhaust port seat, so that the gas can only be exhausted from the exhaust port.

Detailed Description

See the drawings. In this embodiment, the exhaust valve 1 is connected to the pipeline system as a tee, one end of the tee is used for connecting the pipeline, one end is used for exhausting, and the other end is closed by a plug for standby. In the embodiment, there is a valve seat 10, and a thin passage 13 is arranged between the valve seat and the pipeline system, and the gas in the pipeline can reach the valve seat through the passage 13 for exhausting. The wall of the valve seat has a through hole 11 located approximately near the passageway 13. The valve seat has an internal thread on its inner wall and an annular ridge 12 on its outer wall. The exhaust port seat 20 is tubular with two open ends and is provided with an exhaust port 30 which is communicated with the outside; the inner wall of the exhaust port seat is provided with an annular groove 21. The front end of the plug 40 is provided with a plug 41; the front part of the plug is provided with external threads which are meshed with the internal threads on the inner wall of the valve seat; the middle part of the plug is provided with two sealing rings 42, 43, and the rear end is designed into a hexagon suitable for screwing.

The exhaust port seat 20 is sleeved outside the valve seat 10, and the exhaust port seat and the valve seat are in clearance fit; at the same time, the annular groove 21 is matched with the annular rib 12, so that the exhaust port seat and the valve seat are axially positioned and can freely rotate in the circumferential direction.

The plug 40 extends into the valve seat 10 and is in threaded engagement therewith. When the screw is screwed down, the plug 41 blocks the passage 13 so that the gas in the pipe system cannot reach the valve seat via the passage 13; both sealing rings 42, 43 are now in the valve seat. When the screw is unscrewed, the plug is retracted by a certain stroke, at which time the plug 41 leaves the passage 13, and the gas in the pipe system can reach the valve seat via the passage 13; at least the seal ring 43 is still in the valve seat, and the gas cannot be discharged through the gap between the valve seat and the plug, but enters the gap between the valve seat and the exhaust port seat through the through hole 11 on the valve seat; since the annular groove 21 has a certain sealing effect in cooperation with the annular rib 12, the gas is discharged through the gas discharge port 30 in a direction depending on the direction of the gas discharge port 30.
