Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, fig. 3 and fig. 4, a connection structure of a radiator water chamber and a water drain valve, including a water chamber 1 and a water drain valve 2, the water drain valve 2 is installed on an installation hole 3 of the water chamber 1 through a thread structure, a first groove 4 is opened on a circumference of the part of the water drain valve 2 extending into the installation hole 3, a sealing ring 5 is installed in the first groove 4, the sealing ring 5 is in interference fit with an inner wall of the installation hole 3, a diversion hole 6 is opened on an inner wall of the installation hole 3, the sealing ring 5 moves in the installation hole 3 along with the movement of the water drain valve 2, the diversion hole 6 is located in a movement path of the sealing ring 5, a bypass flow channel structure 7 is arranged on the water chamber 1, the diversion hole 6 is communicated with the flow channel structure 7, and the other end of the bypass flow channel structure 7 is communicated with an inner hole of an installation pin 8 of the water chamber 1.
In the present embodiment, a knob 11 is provided at a portion of the drain valve 2 located outside the mounting hole 3, so as to adjust the opening and closing of the drain valve 2.
In use of the present embodiment, as shown in fig. 1, when the discharge valve 2 is mounted in the mounting hole 3, the packing 5 is pressed between the mounting hole 5 and the discharge valve 2 to form a sealing surface, so that the mounting hole 3 is sealed.
When the water drain valve 2 is screwed in, the diversion hole 6 is positioned outside the sealing ring 5, and at the moment, water in the water chamber 1 cannot flow out. When the water chamber 1 needs to discharge water, as shown in fig. 2, the water discharge valve 2 is screwed outwards to make the diversion hole 6 located at the inner side of the sealing ring 5, at this time, because the sealing ring 5 and the mounting hole 3 are still in a sealing state, water cannot be sprayed out from the knob 11 end of the water discharge valve 2, operators cannot be scalded, and the water discharge device is safe and reliable.
