DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] Preferably, the flow valve includes a valve body 24 and a rubber ring 10, a large heating valve pressure cap 11 and a screw rod 12 which are arranged in the valve body 24 from top to bottom. The screw rod 12 is adjustable and installed in the large heating valve pressure cap 11. The large heating valve pressure cap 11 is connected to a sheath 13. The rubber ring 10 is arranged between the large heating valve pressure cap 11 and the sheath 13.
