Abstract

PURPOSE: To reduce clogging caused by dirt or the like and facilitate disassembly for cleaning at the time of clogging being generated by sharpening the tip of a switching valve into needle shape, and fitting a valve seat to a casing integrally with a joint and removably in the opposite direction to the switching valve. CONSTITUTION: The tip of a rod 9 is sharpened in needle shape so that the nearly side part of the tip comes in contact with a valve seat 5. The tip of a needle-like part is therefore protruded downward from the valve seat 5, so that the passage of the valve seat 5 is not clogged with the tip of the rod 9. Even in the case of being clogged, the needle-like tip of the rod 9 breaks clogging material or pushes it out to open the passage of the valve seat 5. In case the passage of the valve seat 5 is clogged or in case of cleaning even if not clogged, a joint 7 on the valve seat 5 side is removed. The valve seat 5 integral with the joint 7 can thereby removed so as to facilitate the cleaning of the valve seat 5, the replacement of an O-ring used for the valve seat 5, and the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an electromagnetic drain trap for discharging drain water consisting of water in compressed air condensed by a compressed air dehumidifier or the like to the outside of a system such as a compressed air pipe. Is.

[0002]

2. Description of the Related Art Generally, the valve tip of an electromagnetic drain trap for intermittently discharging the stored drain as in the present invention is made flat or slightly conical.
The spring pressed against the valve seat to prevent leakage during non-discharge (accumulation of flow) (see Japanese Utility Model Publication No. 62-10559). Further, there is known a structure in which a cover accommodating a valve inside is screwed and fixed to a casing so that the valve together with the valve can be attached and detached in an upward direction, while a valve seat is screwed and fixed to a drain pipe. Although the valve seat is formed separately from the casing, it is attached to the bottom of the casing, and it is extremely difficult to disassemble the valve seat at the installation site.

[0003]

However, in such a structure, when dust or the like is clogged in the passage in the vicinity of the valve seat portion, the dust or the like is merely pressed against the valve seat by the valve, and the dust or the like is removed. Remove the drain trap by yourself,
In many cases, it could not be discharged to the outside. On the other hand, if the mixed powder accumulates or large dust clogging the valve seat, and the drain does not flow down,
You have to disassemble and clean it. As in the invention described in Japanese Utility Model Publication No. 62-10559, it can be disassembled by screwing the cap into the casing to make it detachable. However, when the cover is removed upward as in the invention, The valve seat is in the back side where it is difficult for hands or cleaning tools to enter, making it difficult to clean the area around the valve seat. Further, in order to facilitate cleaning, there is a problem that a detachable portion must be wide.

Therefore, in view of the above problems, the present invention is an electromagnetic drain for a compressed air dehumidifying device in which dust or the like is unlikely to be clogged between the valve and the valve seat, and even if the valve is clogged, the valve seat portion can be easily cleaned. The purpose is to provide a trap.

[0005]

In order to achieve the above object, in the present invention, the tip of the on-off valve is sharpened like a needle, and the valve seat can be attached and detached integrally with the joint in the direction opposite to the on-off valve. Provided is an electromagnetic drain trap which is less likely to be clogged with dust and the like and is easily disassembled for cleaning even if it is clogged by being attached to a casing.

[0006]

When the tip of the on-off valve is sharpened like a needle as in the present invention, even if a large dust or the like is caught on the valve seat portion, the dust or the like is pushed down while being crushed by the electromagnetic force, Moreover, since the tip penetrates ahead of the valve seat portion, dust and the like easily pass through the valve seat portion and fall to the drain discharge port side.
Even if it is necessary to disassemble and clean the dust because the dust does not drop or adheres to the dust, the valve seat portion can be removed integrally with the joint, and the dust can be easily cleaned.

[0007]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. 1 and 2 show an embodiment of an electromagnetic drain trap of a compressed air dehumidifying device of the present invention.
Indicates that the valve is closed.

Reference numeral 2 denotes a body of the electromagnetic drain trap 1 of the present invention, which has a drain opening 3 on its side surface, which communicates with a compressed air dehumidifier (not shown), and communicates with a drain passage 4 in the body 2. Drain passage 4 is drain entrance 3
The body 2 is opened horizontally, and the body 2 is bent at a right angle downward at the center of the body 2. The hole in the body 2 is T-shaped and is also open upward. Further, on the inner surface near the tip of the bent portion of the passage 4 bent downward at a right angle, O
A joint 7 having a cylindrical valve seat 5 in which a ring 6 is fitted is fastened. Hole 8 on the opposite side of drain passage 4 bent at a right angle
An on-off valve, a rod 9, penetrates through the
It is controlled by a solenoid coil 10 fixed to the top of the body 2. A spring 11 for pulling the rod 9 upward, that is, away from the valve seat 5, is housed in the solenoid coil 10.

[0009]

In the drain trap 1 of the present invention having the above-described structure, the moisture in the compressed air condensed by being cooled in the compressed air dehumidifying device passes through the connecting pipe to the device and the like in the body 2. It flows from the drain inlet 3 into the drain passage 4 and stores up to the rod 9 and the valve seat 5. At this time, the rod 9 is pressed against the O-ring 6 of the valve seat 5 by the electromagnetic force of the solenoid coil 10 to seal the drain inlet 3 side. Energization of the solenoid coil 10 is stopped irregularly by a storage flow sensor provided in the drain system passage or periodically by a timer. When the energization is stopped, the rod 9 is pulled up by the spring force, and the drain passage 4 is opened apart from the valve seat 5. A hose or the like is connected to the lower end of the joint 7. Drain dust and the like flowing as described above are most likely to be clogged in the narrowing portion. The same applies to the clogging of the semi-kneaded drain.
Therefore, the valve seat 5 portion is most likely to be clogged.

Therefore, according to the present invention, the tip of the rod 9 is made to have a needle-like shape so as to abut the valve seat 5 substantially laterally of the tip. Therefore, the passage of the valve seat portion is not always blocked by the tip of the rod 9. Also, even if it gets stuck,
Since the tip of the rod 9 is needle-shaped, it crushes clogged objects,
Or it can be pushed out to open the passage in the valve seat.
Furthermore, if the passage of the valve seat 5 is clogged, or if cleaning is required even if it is not clogged, the joint 7 on the valve seat 5 side can be used.
The valve seat 5 integrated with the joint 7 can also be removed by removing the valve seat 5, and the valve seat 5 can be easily cleaned and the O-ring 6 used for the valve seat 5 can be easily replaced. Further, when reattaching, the joint 7 may be screwed in, which is easy.

[0011]

As described above, according to the drain trap of the compressed air dehumidifying device of the present invention, there is no clogging of the valve seat portion, and even if the valve seat portion is clogged, the valve seat portion can be easily attached and detached. It is possible and easy to clean.
