Embodiment Construction
[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 As shown, in view of the problem that the water supply pipeline is easy to freeze because the water tap is closed, the present invention makes the water flow out from the antifreeze pipe 3 by adding an antifreeze pipe joint 3 between the water faucet 1 and the water supply pipe 2 (equivalent to the water supply pipeline). , the route of the water flow is changed, even if the water tap 1 is closed, the water in the water supply pipe 2 will not stop flowing, that is to say, closing the water tap 1 will not cause the water supply pipe 2 to freeze. By adding the antifreeze pipe joint 3 between the water tap 1 and the water supply pipe 2, the freezing problem of the water tap 1 and the water supply pipe 2 is no longer related, thereby freeing the water tap 1 and enabling the water tap 1 to be used normally.

The invention provides an anti-freezing pipe joint. The anti-freezing pipe joint comprises a main pipe joint, a pipe joint outer cover and a pipe joint cap, wherein the main pipe joint comprises a joint and a water outlet channel, an upper end of the water outlet channel is communicated with the joint; a lower end of the water outlet channel is unclosed; the joint is in screwed connection with a water supply pipe; external screw threads are disposed on an outer wall of the water outlet channel; the bottom of the pipe joint cap is sealed and the top of the pipe joint cap is open; a sealing gasket is disposed on one end of the bottom in the pipe joint cap; a draining tank communicated with the outside is formed in an inner wall of the pipe joint cap; internal screw threads matched with the external screw threads are disposed in the position, without the draining tank, of the inner wall of the pipe joint cap; the pipe joint outer cover comprises a cover bottom and a cover arm; a through hole is formed in the cover bottom; the internal screw threads matched with the external screw threads are disposed on the inner wall of the through hole; the outer pipe joint cover is screwed into a connected part of the joint and the water outlet channel through screw-thread fit; the arc length of the cover arm is greater than the overall length of the water outlet channel and the pipe joint cap so that the cover arm covers the draining tank. By use of the anti-freezing pipe joint, the water supply pipe can be prevented from freezing.
Description
technical field [0001] The invention relates to the technical field of pipelines, and more specifically relates to an antifreeze pipe joint suitable for preventing water pipes from freezing in winter. Background technique [0002] The construction workers of construction projects usually live at the construction site, so there must be no lack of water source. The water source is the water source of temporary facilities. If the construction site is in the north, the weather will be very cold after entering winter. On the ground surface, the water supply pipeline laid on the surface is easy to freeze. The existing method is to wrap a layer of heat preservation pipe outside the water supply pipeline. Although this method can play a certain role in heat preservation, it cannot avoid the water supply pipeline from freezing. embarrassing situation. [0003] For the above problems, the folk method is to open the faucet a little to let the water flow out continuously, so as to alle...
