Description

[Detailed Description of the Invention] The present invention relates to a valve with a filter that removes minute dusts and foreign substances in a water stream very easily and enlarges the area of the water stream, and has almost no water flow resistance.

Usually, when the valve is in use, foreign matter such as dust adheres to the inside of the pipe, which may accumulate and cause remarkable resistance to the flow of water.

In particular, in the actuating mechanism portion such as the stop valve, the adherence rate of the foreign matter is so great that the operation is hindered and the stop valve function becomes impossible.

In view of such drawbacks, the present invention makes it extremely easy to remove foreign matter such as dust and dust, and also facilitates various maintenance work in the valve easily and easily. The inside of one of the water passages is expanded to form a filter chamber having a large diameter, which is integrally connected to a filter holding pipe, and a groove groove is formed on the wall surface of the filter chamber in an inclined manner. An object of the present invention is to provide a valve with a filter, characterized in that a substantially hemispherical filter is fitted in the groove in a grooved manner so as to be detachable.

Hereinafter, referring to the drawings illustrating a concrete structure of the present invention, a filter holding pipe (2) is extended from a water inlet (1) 'of a valve body (1) and the filter holding pipe (2) is provided. The inner diameter of the filter chamber (3) is expanded to form a filter chamber (3), and the upper wall of the filter chamber (3) is connected to the non-upstream side and the lower wall to the upstream side. A hemispherical filter (5) having a grooved groove or a step-like filter locking portion (4) that can be formed at a constant inclination angle is provided, and the opening surface of the filter locking portion (4) is opened upstream. It is configured so that it can be detachably locked in the expanding filter chamber (3) in an inclined shape.

Further, a water passage pipe connecting portion (6) is provided at one opening of the filter holding pipe (2) to connect the water passage pipe (7) in a freely connectable manner.

Further, in the present invention, large-diameter openings (8) are provided at both sides of the filter holding pipe (2) or one of them, or at appropriate places such as above and below, and each of the openings (8) is provided. Is fastened with the plug (9). When necessary, simply remove the plug (9) where it is needed. Not only the internal inspection but also the detachment work of the filter (5) can be done from any direction. It can be done easily and easily.

1 and 2 show a straight type stop valve, and FIGS. 3 and 4 show an L type stop valve, but the present invention is limited to such a type. Instead, it can be optionally used with any type of valve.

As described above, since the valve with a filter according to the present invention has the above-described structure, it is possible to pass clean cold / warm water free from dust and foreign matter by mounting it on the cold / hot water inlet of a cooling / heating device, for example. It is possible to protect the water flow mechanism of the air conditioner and to eliminate the cause of failure fundamentally.

As described above, according to this invention, a large-diameter filter chamber (3) is formed in a part of the valve body (1), and an upper locking portion is provided on the inner wall surface of the diameter-expanding filter chamber (3) on the non-upstream side. A filter locking part (4) for forming the lower locking part on the upstream side at a constant inclination angle in the front and rear is provided and the filter locking part (4)
A hemispherical filter (5) having an opening surface on the upstream side is detachably locked in the diameter-expanding filter chamber (3) in a slanting manner. The flow rapidly blunts due to the action of the expansion of the diameter expansion filter chamber (3) and the curved inner surface of the opening side of the hemispherical filter (5), and at the same time vortexes on the curved inner surface and passes through the filter surface. Filter (5) by such a blunt flow of water flow
Fine dust, foreign matter, etc. in the water flow adhering to the surface naturally fall and settle on the bottom of the bowl on the opening side of the hemispherical filter (5) which is slantingly locked in the filter chamber (3), and therefore the bowl It is possible to easily and easily remove the above-mentioned filter (5) and the outside to the outside without dissipating any foreign matter accumulated on the bottom into the filter chamber (3).

Especially in this invention, unlike a conventional cylindrical or hemispherical filter simply fitted in the valve chamber,
The hemispherical filter (5) is fitted in the expanding filter chamber (3) in a slanted manner, so that the filter action surface has a center line as compared with a normal filter action surface on the entire surface of the filter. The lower working area expands, so that the resistance of the water flow passing through the filter also varies up and down, and there is almost no clogging in the upper half of the filter surface, and a smooth water flow body can be obtained at all times.
