Front-mounted filtering purifier

Technical Field

The utility model belongs to the technical field of the aqueous cleaning, a leading filtration purification ware is related to.

Background

Water is one of indispensable resources in daily life of people, and every family has a tap water pipe to communicate with each other. However, water is conveyed through an iron pipe, and the iron pipe inevitably generates impurities such as scrap iron and rust after being used for a long time, and if the iron pipe is directly drunk, the health of people is affected.

Therefore, people design a pre-filter, the pre-filter is first coarse filtration equipment for water used in a whole house, and large granular substances such as silt, rust, ova, red worms and the like in tap water can be filtered through a filter screen. The pre-filter is typically installed at the front end of the pipe, i.e., the access end, and is therefore named "pre-filter" by the word "pre-filter".

However, the existing prefilter only has the function of filtering solid impurities, cannot purify water entering a home, has single function and limited function, and is difficult to meet the use requirements of people.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that prior art exists, provide a leading filtration purification ware, solved the problem of current leading filter function singleness.

The purpose of the utility model can be realized by the following technical proposal:

leading filtration purification ware, including the valve body that has water inlet and delivery port, the lateral part of valve body links firmly the inside casing that has the cavity, the casing internal fixation has the filter screen I that is the tube-shape, filter screen I separates the cavity for being located the play water cavity of filter screen one and being located the intake antrum between the filter screen outside and the shells inner wall, water inlet, intake antrum, play water cavity and delivery port communicate in proper order, its characterized in that, be provided with active carbon in the intake antrum, it is provided with the PP cotton to go out the water cavity.

This leading filtration purification ware is when using, corresponds the water inlet and the delivery port of valve body and connects in the water supply pipeline, and rivers flow into the intake antrum from the water inlet, pass a filter screen lateral wall after the first purification of active carbon and enter into the play water cavity in the filter screen one, flow from the delivery port department after the cotton secondary purification of PP. Compared with the prior pre-filter, the filter screen I is adopted for filtering solid impurities, and the water quality is purified through the activated carbon and the PP cotton, so that the functions are more comprehensive, and the water demand of people can be met.

In the preposed filtering purifier, a second filter screen is also inserted in the valve body close to the water inlet. Double filtration, the filter effect is better, and through the prefiltering of filter screen two, the rivers impurity that flows to the cotton department of active carbon and PP is better, reduces purification pressure.

In the above-mentioned pre-filter purifier, the filter holes of the first filter screen are smaller than the filter holes of the second filter screen. In the double filtration, the filtration effect is better because the filter is thick and thin.

In the preposed filtering purifier, a first connecting hole is formed in the corresponding position of the side part of the valve body and the filter screen in a penetrating mode, a plug is connected to the first connecting hole of the valve body in a threaded mode, and the inner end of the plug is abutted to the second filter screen. The end cap connected by the threads can be detached, and the second filter screen can be conveniently cleaned and replaced.

In the preposed filtering purifier, a concave annular positioning groove is formed in the side wall of the valve body opposite to the plug, the second filter screen is cylindrical, one end of the second filter screen extends into the positioning groove, and the other end of the second filter screen abuts against the plug. The position of the second filter screen is positioned through the positioning groove and the plug, the stability of the position of the second filter screen is guaranteed, and then the filtering effect is guaranteed.

In the preposed filtering purifier, the side part of the valve body is also provided with a second connecting hole in a penetrating way, and the second connecting hole is connected with a water hammer eliminating device. The water hammer eliminating device is the prior art and is used for eliminating or reducing the influence of the water hammer phenomenon.

In the preposed filtering purifier, the side part of the shell is also penetrated and provided with an observation port, and the observation port of the shell is fixedly connected with an observation window made of transparent material. Active carbon and the cotton in service behavior of PP in the observation shell through the observation window, be convenient for in time change and wash.

In the above-mentioned pre-filter purifier, the other side of the housing opposite to the valve body is connected with a blowoff valve. After long-term use, the blow-down valve can be opened to lead out water flow so as to flush and blow down the shell.

In the preposed filtering purifier, the side part of the valve body close to the water outlet is also connected with a pressure gauge.

Compared with the prior art, this leading filtration clarifier has the cotton effect of purifying and waterproof hammer of dual filtration, active carbon and PP, further purifies quality of water on the basis of filtering impurity, and the function is various, can satisfy people's water demand.
