Description

[Detailed explanation of the invention] (a) Technical field of the invention This invention targets a drain/kottoku device,
Mainly related to drain and drain devices for radiators.

(b) Background of the technology Generally, in order to remove deteriorated cooling water,
As shown in Figures to Figure 6, the radiator tank 1
is equipped with a drain and drain device.

As shown in Fig. 1, the conventional drain/cottle device first has a seat body 3 with a small diameter screw hole 2 formed therein.
A drain seat a consisting of itself, a drain seat a consisting of a small diameter threaded part itself, a flanged knob 5 on a drain body 4 consisting of a small diameter threaded part itself
The cooling water is drained through the guide groove 7 formed in the drain body 4 by screwing the drain pot b provided with the drain pot b through the gasket 6 and loosening the drain pot b as shown in FIG. 2. As shown in FIG. 3, a seat body 3 having a small diameter screw hole 2 is attached to a drain seat a to which a drain holder 9 having a guide pipe 8 is attached. 5 is provided with the drain socket b through the seal packing 11, and as shown in FIG.
The cooling water is drained through the guide groove 7 formed in the small diameter screw portion 10 and the guide pipe 8 of the Kotoku holder 9 by loosening the screw (see, for example, Japanese Utility Model Application No. 57-44930), and furthermore, as shown in FIG. Tip small diameter hole 12
An O-ring 14 is attached to the drain seat a, which has a guide pipe 8 attached to the lower part of the seat body 3, which has a relatively large protrusion and has a rear end large-diameter screw hole 13 formed therein.
Screw the drain socket b provided with the flanged knob 5 onto the main body 4, which has a small-diameter tip 15 and a large-diameter threaded part 16, and loosen the drain socket b as shown in FIG. There was one that drained cooling water through the main body 3 and through the guide pipe 8.

(c) Prior art and problems However, in the first drain/kottoku device, the direction of the cooling water is not determined during drainage, and this causes the cooling water to scatter, causing a short circuit in the electrical system.
It can corrode and, in the case of hot cooling water, pose a risk of burns. In addition, since the threaded part (main body) 4 of the drain pot b is constantly in contact with cooling water, the threaded part ages, resulting in a lack of durability.

The second drain/kottoku device has good directionality of cooling water during drainage, and is inexpensive because the drain holder 9 is made of resin, but the first
The small diameter threaded part 10 is similar to the drain/cottle device.
The disadvantage is that it lacks durability because it is constantly in contact with cooling water.

Furthermore, the third drain/kottoku device has good directionality of cooling water during drainage, and the O-ring 14 of the drain main body 4 is connected to the small diameter hole 12 at the tip of the seat main body 3.
Since the small diameter portion 15 at the tip fitted with the large diameter threaded portion 16 of the main body 4 does not come into direct contact with the cooling water, the durability is good.

However, in any of the above first to third drain/knock devices, the drain/knock B sometimes comes off due to excessive loosening, and this causes the cooling water to scatter, making it impossible to determine the direction of the cooling water. There is more damage than ever before.

(d) Purpose of the invention This invention was made in view of the above, and prevents the scattering of liquid due to the direction not being determined or the drain socket coming off, and also prevents the threaded part of the drain socket from directly contacting the liquid. It is an object of the present invention to provide a drain and drain device that prevents corrosion due to contact and is inexpensive.

(E) Structure of the invention The structure of the invention is that a drain seat is attached to a seat body with a small-diameter hole at the tip and a large-diameter screw hole at the rear end, and a holder having a guide pipe attached thereto.
- A drain/knock device in which a drain/knock having a flanged knob is screwed onto a drain main body having a small diameter end portion with a ring attached and a large diameter threaded portion, wherein a stop is attached to the inner wall surface of the rear end of the kettle holder. The present invention is characterized in that a beat is provided in the center of the drain seat, and the drain seat is screwed into the drain seat via a slip-off prevention ring that is slidable to the drain seat.

(f) Examples of the invention The invention will be explained in detail below based on the drawings.

FIGS. 7 and 8 show drains and drains according to the present invention.
This shows an example of the Kotsuku device.

Drain seat a has a metal sheet main body 19 in which a small diameter hole 17 at the tip and a large diameter screw hole 18 at the rear end are formed.
A cylindrical holder 21 having a guide pipe 20 is attached to the holder. The Kotoku holder 21 has a guide pipe 20 at the bottom of a resin cylinder.
and an annular locking claw 22 and an annular stopper 23 protruding from the inner wall surface of the front end and the inner wall surface of the rear end of the cylindrical shape. 19' and is attached thereto. On the other hand, the drain pot b is a metal pot in which a flanged knob 28 is provided on a drain main body 27 having a small diameter portion 25 at the tip with an O-ring 24 attached and a large diameter threaded portion 26. A protruding bead 32 is provided. A drain socket b is screwed onto the drain seat a through a slideable resin-made slip-off prevention ring 30 having stoppers 29 on the top and bottom of the ring, and is fixed to a radiator tank 31.

With such a drain/knock device, when draining the cooling water from the tank 31, loosen the drain/knock b and make sure to remove it from the large-diameter screw hole 18 at the rear end of the seat body 19, as shown in Figure 8. After that, by pulling the cooling water toward you, the cooling water is drained from the drain seat a to the drain holder 21 and the guide pipe 20.
Water can be drained out of the tank 31 through the tank 31.
At this time, since the drain seat b is attached to the drain seat a via the slideable slip-off prevention ring 30, the cooling water will not come out from the drain seat a, and the cooling water will pass through the open part of the drain seat a. Drainage is carried out by the guide pipe 20 provided at the lower part of the holder 21. Therefore, the scattering of cooling water due to the drain drain b coming out and the scattering of cooling water due to the directionality not being determined can be prevented, and short circuits and corrosion of the electrical system caused by scattering of cooling water, or hot cooling water can be prevented. The risk of burns is also eliminated.

Furthermore, according to this drain/cottle device,
Insert the Kotoku body 2 into the small diameter hole 17 at the tip of the seat body 19.
Small diameter portion 25 at the tip with the O-ring 24 of No. 7 attached
Since the drain socket B is screwed onto the drain seat a in a state where the drain socket B is fitted, the large diameter threaded part 26 of the drain socket B does not come into direct contact with the cooling water, and corrosion and aging caused by the cooling water is reduced. . Therefore, the durability of the drain device is also increased.

In addition, when draining the cooling water, the drain pot b is removed from the large-diameter screw hole 18 at the rear end of the seat body 19 and pulled toward you, so the drain pot b is wide open and the cooling water drains out. can be quickly discharged in a short period of time. Moreover, in the case of this drain/kottoku device, by making the drain holding body 21 and the falling-off prevention ring 30 made of resin,
You can get sufficient functionality at a low price.

Incidentally, FIG. 9 is an exploded perspective view of the drain and drain device of the present invention shown in FIGS. 7 and 8.

The above embodiment is merely an example, and the structure of the knob, guide pipe, etc. is not limited. Also,
Although the drain/cottle device for a radiator is shown, it goes without saying that the drain/cottle device for other purposes attached to other tanks can be used.

(g) Effects of the invention As described above, according to the invention, short circuits and corrosion in wiring systems can be prevented by preventing liquid from scattering due to the direction not being fixed or drains coming off, and Eliminates the risk of burns from liquid. Furthermore, the threaded portion of the drain can be prevented from being corroded by direct contact with liquid, increasing its durability, and providing sufficient functionality at a low cost.
