Rapid installation type anti-freezing faucet

Abstract

The invention discloses a rapid installation type anti-freezing faucet. A valve core is of a pipeline structure with water feeding from the lower portion and discharging from the upper portion; the lower portion of an outer tooth rotation rod is connected with a movable ceramic chip through a convex groove structure; the upper portion of a fixed seat is welded to the lower portion of a fixed pipe;a lifting inner pipe is arranged in the fixed pipe; an inner tooth connector is welded to the lower end of the lifting inner pipe and internally provided with a one-way valve, and the inner tooth connector is in clearance fit with an outer tooth on the upper portion of the outer tooth rotation rod; a locking nut and a fixing connection nut sleeve the upper middle portion of the fixed pipe; a clearance is formed between the lower portion of the fixing connection nut and the fixed pipe; and the upper end of a pre-buried pipeline is inserted into the clearance and connected with an internal thread of the fixing connection nut. According to the rapid installation type anti-freezing faucet, the effects that water is conveniently used outdoors in winter, and the pipeline and the faucet are freeof freezing and cracking are ensured, engineering construction is not needed, the market vacancy is filled in, no energy source is wasted, the situation that heat is preserved by consuming energy isavoided, professional staff construction is not needed, installation, maintenance and replacement can be achieved only through a simple tool, installation is rapid, and maintenance is convenient and fast.

Description

technical field [0001] The invention relates to an outdoor anti-freezing faucet, in particular to a quick-installed non-freezing faucet. Background technique [0002] There are more and more types of similar antifreeze products on the market. The most common type is the emptying type faucet. Its working principle is to discharge the residual water in the standpipe into the underground seepage pool after closing the valve core. This kind of antifreeze faucet needs to dig a deep pit for pre-buried, and needs to use cement and bricks. Building materials such as sand and gravel require professional construction work and plumbing work at the same time, which is time-consuming and labor-intensive, and the project volume is large; the service life of seepage tanks and water nozzles is very short, and secondary construction is required once problems occur. The other is to rely on heat preservation, electric heating, etc. to achieve the antifreeze purpose, which has poor safety and ...

Problems solved by technology

The most common type is the emptying type faucet. Its working principle is to discharge the residual water in the standpipe into the underground seepage pool after closing the valve core. This kind of antifreeze faucet needs to dig a deep pit for pre-buried, and needs to use cement and bricks. Construction materials such as sand and gravel require professional construction work and plumbing work at the same time, which is time-consuming and labor-intensive, with a large amount of work; the service life of seepage pools and water nozzles is very short, and secondary construction is required once problems occur

The other is to rely on heat preservation, electric heating, etc. to achieve the purpose of antifreeze, which is extremely poor in safety and stability, which not only wastes energy, but also increases capital investment.
