By providing the pipe cover, the top of the vertical pipe can be sealed, and it is convenient to disassemble the pipe cover and disassemble and replace the floating block. By providing the exhaust mechanism, it is convenient to discharge the excess gas in the inner cavity of the valve body, so that the heating system circulates smoothly.

[0006] In the above-mentioned high temperature resistant automatic exhaust heating valve, a sealing plate is provided at the top of the vertical pipe, an air outlet is provided on the surface of the sealing plate, a sealing block is connected to the bottom of the sealing plate via a rotating shaft, a connecting rod is connected to the right side of the sealing block via a rotating shaft, and the bottom of the connecting rod is connected to the floating block.

[0007] In the above-mentioned high temperature resistant automatic exhaust heating valve, the bottom of the plugging cover penetrates the inner cavity of the pipe cover, and the surface of the plugging cover is threadedly connected to the inner wall of the pipe cover. By setting the plugging cover, the top of the vertical pipe can be sealed, and the heating valve can be sealed during the inspection of the radiator, which is convenient for the maintenance of the radiator.

[0008] In the above-mentioned high temperature resistant automatic exhaust heating valve, the left side of the valve body is threadedly connected with a knob, and the right side of the knob is connected with a valve block. By setting the knob and the valve body to be threadedly connected, it is convenient to drive the valve block to move horizontally to realize the opening and closing of the valve body.

[0009] In the above-mentioned high temperature resistant automatic exhaust heating valve, a locking mechanism is arranged at the top of the knob, and the locking mechanism comprises a fixed tube, the bottom of the fixed tube is fixedly connected to the valve body, the inner wall of the fixed tube is fixedly connected to a spring, the top of the spring is fixedly connected to a pull rod, the top of the pull rod extends to the outside of the fixed tube and is fixedly connected to a pull plate, the bottom of the pull plate is fixedly connected to a card block, and a card slot is provided at the top of the knob. By arranging the spring, tension is generated on the pull rod, prompting the pull rod to drive the pull plate and the card block to move downward, so that the card block is firmly connected to the card slot, and the return of the pull rod is facilitated at the same time.

[0010] In the above-mentioned high temperature resistant automatic exhaust heating valve, the bottom of the clamping block extends to the inner cavity of the clamping slot, and a pull ring is welded on the top of the pull plate. By providing the clamping block and the clamping slot, the knob can be locked and fixed, which improves the stability of the knob and avoids the valve from being opened by mistake due to accidental touching of the knob.
