Description

An inclined flow channel magnetic drain valve

technical field

The utility model relates to a valve, which is especially suitable for magnetic filtration in the field of building heating pipes.

Background technique

Due to its strength, temperature resistance and pressure resistance, steel pipes are often used for heating and other heat medium transportation. Long-term contact between the inner wall of the steel pipe and the heat medium such as water will cause corrosion, and iron impurities will precipitate, resulting in the yellowing of the heat medium. In addition to steel pipes, iron pipe parts such as radiators and boilers that are in contact with the heat medium also have such problems.

There are two ways to deal with iron impurities in heating pipes. First, the pipes are regularly removed and cleaned. Second, increase the filter for iron impurities. The circulating heat energy medium passes through the filter, and the iron impurities in it are adsorbed on the magnet of the filter, and the iron impurities can be easily discharged through the close drain valve. A similar drain valve is shown in Bulletin No. CN 203421205, "A Filter Drain Valve", but the drain valve can only filter particulate impurities through the filter screen and discharge through the drain valve at the lower end, and cannot filter tiny iron impurities.

In order to achieve the purpose of removing iron impurities, the prior art adopts the "Magnetic Filter and its Magnetic Filter Assembling Method" of the publication number CN 109847934A, installs a magnetic part, absorbs the iron impurities in the fluid medium, and uses a wrench to rotate it during cleaning. Take out the bonnet, and at the same time clean other particles and impurities on the filter, manually wipe away the iron impurities on the magnetic rod. Although impurities such as iron can be removed, as in the previous prior art, a wrenching tool is required and removal is troublesome.

SUMMARY OF THE INVENTION

Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 to FIG. 3, an inclined flow channel magnetic drain valve includes a valve body 1, the valve body 1 is generally in the shape of a "bu", and the vertical part of the valve body 1 is provided with a through hole 10, the through hole 10 The upper part is a large-diameter hole 13, and the lower part is connected with a small-diameter hole 14; a sleeve 2 is installed in the through hole 10, the sleeve 2 and the upper part of the through hole 10 maintain an annular leakage gap 12, and a locking cap 3 withstands the sleeve. 2 to fix it; a magnetic rod 4 is arranged in the sleeve 2; the side of the valve body 1 is also provided with a side through hole 15, and the side through hole 15 communicates with the connection of the large-diameter hole 13 and the small-diameter hole 14; The side through hole 15 is provided with a valve 5 .

The side through hole 15 designed in this application is connected with the large diameter hole 13 and the small diameter hole 14, and has a good effect. First, it maximizes the drainage area; second, impurities will not accumulate in it when they are removed. If the position of the connection between the side through hole 15 and the large diameter hole 13 and the small diameter hole 14 is too high or too low, the effect is poor.

The valve 5 is a ball valve with a valve ball 50 and an opening and closing valve stem 51 . By directly rotating the valve stem 51 with a screwdriver or handle, the valve ball 50 can be rotated to open the side through hole 15 to discharge the sewage from the pipeline. The valve 5 can also be a stop valve, or there is no valve, and the water outlet of the side through hole 15 is directly blocked with a plug.

The outer diameter of the locking cap 3 is provided with a threaded portion 30, and the end of the threaded portion 30 is also screwed with a hand-tightening cap 6, and the hand-tightening cap 6 is fixed with the magnetic rod 4. The upper part of the threaded part 30 of the locking cap 3 is screwed on the valve body 1 to support the sleeve 2 and the gasket 9, and the lower part of the threaded part 30 is matched with the screw cap 6. One piece is multi-purpose and reduces the number of product parts. Screw the cap 6 and the magnetic rod 4 to fix it by adhesive or screw. The magnetic rod 4 can be pulled out by simply unscrewing the cap 6 by hand.

A positioning cap 7 is provided on the upper end of the valve body 1 for positioning the orientation of the side through hole 15 . The upper end of the valve body 1 is of a threaded structure. When the thread is matched with the pipe components, the direction of the side through hole 15 is not easy to locate. When installing the inclined flow channel magnetic drain valve of the present application, the orientation of the side through hole 15 needs to be positioned, and the structure of the positioning cap 7 solves this problem very well. When it is almost matched with the pipeline, the positioning cap 7 can be rotated up and down to hold it up. The sealing ring 70 on the positioning cap 7 can also play the role of connecting and sealing with the pipeline.

As shown in FIG. 3 , the inclined flow channel magnetic drain valve is installed at the bottom of the pipeline container 8 and on the flow channel through which the fluid medium passes. When the iron impurities on the fluid medium flow through, they are sucked by the magnetic rod 4, attached to the sleeve 2, and no magnetic impurities fall and accumulate in the annular contamination gap 12 of the large-diameter hole 13 and part of the side through holes 15. . When discharging sewage, as long as the magnetic rod 4 is pulled out, the iron impurities adsorbed on the sleeve 2 will fall to the bottom due to the specific gravity, and the iron impurities and other impurities can be discharged by opening the valve 5. The present application is especially suitable for heating pipes with circulating medium, because of the high temperature of the medium and the long-term circulation, iron pipes are more prone to corrosion. In addition, the utility model has only one conventional interface, which can conveniently replace the conventional drain valve on the pipeline, thereby increasing the function of removing iron impurities.

The utility model provides a drain valve with a novel structure, which is convenient and quick to discharge sewage; the drain valve can realize sewage discharge by using one interface, has a compact and reasonable structure, is novel and unique, and is especially suitable for pipes such as heating, and increases the magnetic decontamination function. , It is highly replaceable for ordinary drain valves and has market competitiveness.
