Description

A plastic pipe water separator

technical field

The utility model relates to the field of water supply equipment, in particular to a plastic pipe water separator.

Background technique

As disclosed in the patent 200420044678.1, in the existing water distributor with several water outlet pipes, the connection between the water outlet pipe and the main body of the water distributor is to first set the opening in the water inlet pipe of the water distributor, and then process the connection end surface of the water outlet pipe Form a saddle shape corresponding to the opening, insert the outlet pipe into the opening, and weld the outlet pipe to the main body of the water distributor from the outside by hot-melt welding. This kind of water separator is formed by inserting the water outlet pipe into the opening of the main body of the water separator and then welding. The water outlet pipe tends to protrude into the opening. In this way, the protruding part of the water outlet pipe in the main body of the water distributor forms a gap with the opening of the main body of the water distributor, and the welding process outside cannot eliminate this gap. The gap forms a dead angle for water flow, and stolen goods are easy to accumulate in this dead angle to breed bacteria, which will pollute the water quality over time. The water separator is difficult to maintain, and the cast iron pipe is not corrosion-resistant and easy to oxidize, which easily pollutes the water quality.

The existing water distributor is also connected by a combination of several plastic pipe connectors. The main body of the water distributor and the water distribution pipe are usually connected by threads. This water distributor has the following disadvantages: many connectors, complex structure, difficult maintenance, There are many areas where water leaks occur.

Some water separators in use are mostly welded by a single tee. The central moment and size of each water distribution pipe joint are adjusted during welding. The requirements for welding technicians are quite high, the size control is quite difficult, and it is prone to deflection. Phenomena, the efficiency is also very low.

The peripheral equipment of the water distributor in the water supply system is mostly water meters, faucets, valves, etc. The connections of these peripheral equipment are often threaded, and almost all of them cannot meet the directional requirements after the connection is completed. For example, after the water meter is installed, the dial surface must be visible, and after the faucet is installed, the water outlet must be downward.

Utility model content

Detailed ways

As shown in Figure 1, a plastic pipe water distributor includes a water inlet pipe 1 and an outlet pipe joint 2, characterized in that the water inlet pipe 1 and the water outlet pipe joint 2 are an integrated structure of one-time pressurized injection molding; Between the water inlet pipes 1 and between the water outlet pipe joint 2 and the water outlet pipe fittings, hot-melt socket connections are used; the water separator is made of polypropylene or polyethylene or polybutene; the plastic pipe water separator The number of upper water outlet pipe joints can be set as required, usually 3 or 5 water outlet pipe joints.

As shown in FIG. 2 , it is a schematic diagram of a plastic pipe water distributor with three outlet pipe joints provided by the utility model. In the picture, the water inlet pipe and the three outlet pipe joints set on it are processed and injected by an injection molding machine, which has high reliability; the central moment and size of each water distribution pipe joint are guaranteed by the process and mold, and the required dimensions can be accurately controlled.

As shown in FIG. 3 , it is a schematic diagram of a plastic pipe water distributor with 5 outlet pipe joints provided by the utility model. The only difference between this water distributor and the plastic pipe water distributor with 3 outlet pipe joints is the number of water outlet pipe joints.

The outlet pipe joint of the water distributor adopts a socket connection, which solves the problem of directionality in connection with peripheral accessories. The peripheral equipment of the water distributor in the water supply system is mostly water meters, faucets, valves, etc. The connections of these peripheral equipment are often threaded, and almost all of them cannot meet the directional requirements after the connection is completed. For example, after the water meter is installed, the dial surface must be visible, and after the faucet is installed, the water outlet must be downward.

The outlet pipe joint of the water distributor adopts a hot-melt interface structure. When connecting with the thread, copper-plastic or steel-plastic conversion pipe fittings are used, and the plastic end is hot-melt connected with the water distribution pipe joint, and the directionality is guaranteed by the hot-melt connection. For example, the water distributor is connected to the valve, and the switch of the valve must be outward. If the water distributor with other thread structures is used, since the thread has been fixed and cannot be rotated, it may cause the water valve switch surface to not face outward when the water valve is tightened. The water meter can be screwed tightly on the steel-plastic or copper-plastic pipe fittings by using the plastic water distributor, and then the plastic end of the steel-plastic or copper-plastic pipe fittings can be hot-melt connected with the water distributor, so as to ensure the directionality and tightening force of the water valve . Moreover, the plastic pipe water separator also has the advantages of simple structure, corrosion resistance, light weight, low price, convenient installation and use, easy maintenance, and high reliability.

The inner diameter of the water inlet pipe of the water distributor is kept consistent as a whole, so that the water inlet pipe can be connected with the pipe after being cut longitudinally. The number of outlet pipe joints can be adjusted arbitrarily, and any transformation between two branches and multiple branches can be realized. The water divider is used in urban and rural one-household-one-meter projects or occasions where the fluid in the main pipeline is concentrated and evenly diverted to the branch pipelines.

Although an embodiment of the utility model has been described in conjunction with the accompanying drawings, various deformations or modifications that can be made by those skilled in the art within the scope of the appended claims without creative work still fall within the protection scope of this patent.
