DETAILED DESCRIPTION

The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

With reference to FIGS. 1-3 , an embodiment of the utility model discloses: a valve casting with an environmentally friendly heat treatment function, comprising a valve body 1, a water inlet channel and a water outlet channel opened on the valve body 1, and a heating rod 8, wherein a fluid channel 6 is opened inside the valve body 1, and the fluid channel 6 is filled with water, a connecting channel is opened on the valve body 1, and the connecting channel is connected to the fluid channel 6, a sealing plug 4 is threadedly connected to the connecting channel, a sealing ring is provided between the sealing plug 4 and the valve body 1, a socket channel is opened on the sealing plug 4, one end of the heating rod 8 is penetrated into the socket channel, an anti-detachment device is provided on the sealing plug 4 for preventing the heating rod 8 from detaching, and the other end of the heating rod 8 is in contact with water for water heating.

Specifically, the anti-slip device includes an anti-slip rod 9 and a sliding plate 10. The anti-slip rod 9 is slidably arranged on the sealing plug 4. The heating rod 8 is provided with an anti-slip groove. One end of the anti-slip rod 9 is inserted into the anti-slip groove, and the other end of the anti-slip rod 9 passes through the sealing plug 4. The sealing plug 4 is provided with a sliding channel. The anti-slip rod 9 is located in the sliding channel. The sliding plate 10 is arranged on the anti-slip rod 9. A spring 11 is sleeved on the anti-slip rod 9. One end of the spring 11 resists the inner wall of the sliding channel, and the other end of the spring 11 resists the sliding plate 10.

When in use, the heating rod 8 is inserted into the connecting channel, and then the sealing plug 4 is threadedly connected to the valve body 1, so that the valve body 1 has an electric heating function, which is convenient and environmentally friendly. Then the heating rod 8 works, so that the heating rod 8 heats the water in the fluid channel 6, thereby increasing the temperature of the valve body 1, so that it will not be frozen, and the valve body 1 is prevented from freezing and cracking, which is beneficial to improving the service life of the valve. When the heating rod 8 is attached with impurities and needs to be cleaned or the heating rod 8 needs to be replaced, the anti-slip rod 9 is pulled, and the anti-slip rod 9 slides and leaves the anti-slip groove, and then the heating rod 8 is removed, and the staff can maintain and replace the heating rod 8, which greatly facilitates the staff's operation.

In order to facilitate heat preservation, a heat preservation channel is opened in the valve body 1 outside the fluid channel 6, and heat preservation cotton 7 is arranged in the heat preservation channel.
