Description

[Detailed Description of the Invention] The present invention relates to a drain device for draining oil from a tank.

Conventionally, as shown in FIG.
Second. If the third room is divided into C1, C2, and C3, each drain device (drain plug) a□v d2? A dj is provided to discharge the oil in each room □, C2, and C3, respectively.

However, this structure has the disadvantage that during drain work, it is necessary to operate as many drain devices as there are rooms, making the operation extremely troublesome.

The present invention has been developed in view of the above circumstances, and its purpose is to provide a drain device that can drain oil from multiple chambers of a tank using one drain device.

Embodiments of the present invention will be described below with reference to FIG. 2 and subsequent figures.

Inside tank 1 is the 1st tank. The first and second partition plates 21 and 2□
．． The third room is divided into 3□, 3□, and 33, and its side wall 1a
A drain device 4 is provided at the bottom of the tank.

That is, a valve body 5 is fixedly installed across a first chamber 31 and a second chamber 3°, and a drain plug 7 is slidably inserted into a valve hole 6 of the valve body 5. The valve hole 6 has a first port 8 that opens into the first chamber 3□, and a second port 8 that opens into the second chamber 3□.
The second port 9 opens to the third chamber 33 through the pipe 10, the third port 11 opens to the third chamber 33 through the annular groove 12, and the drain port 13 opens to the outside through the annular groove 12.

The drain plug 7 is fitted into the valve hole 6 and a large-diameter base 71 having a threaded portion 7a cut therein, which screws into a threaded hole 6a cut concentrically with the valve hole 6 on one end side of the valve body 5. It has a small diameter tip 7° and a hexagonal head 73 protruding outward from the valve body 5, and the small diameter tip 7□ has an axial hole 1 opened at the tip.
6 and a radial hole 17 communicating with the hole 16 are bored, and when the drain plug 7 is screwed in, the large diameter base 71
The sealing surface 14 formed between the small-diameter tip 7□ is in close contact with the valve seat 15 of the valve hole 6, and the valve hole 6 and the annular groove 12 are shut off. 3rd port 8, 11
When the valve hole 6 is blocked and loosened, the sealing surface 14 and the valve seat 15
The valve hole 6 and the annular groove 12 communicate with each other, and the first and third ports 8 and 11 open into the valve hole 6.

After screwing in the drain plug 7,
When the sealing surface 14 shown in the figure is brought into close contact with the valve seat 15, the first and third ports 8, 11 and the valve hole 6 are cut off, and the valve hole 6 and the annular groove 12 are cut off. ．． □Second
．． Third room - 31.3°.

The oil in 33 is not drained.

□''Also, loosen the drain plug 7 and see Figure 5.
When the sealing surface 14 is separated from the valve seat 15 as shown in FIG. The drain port 13 is opened through the drain port 13 .

Therefore, the first. Second. The oil in the third chamber 31, 32, 33 is drained.

In this way, by operating one drain plug 7, the first drain plug 7. Second. The oil in the third room 3□, 32.33 can be drained, making the draining work easier.

In addition, the valve hole 6 and the first and third ports 8 and 11 are connected to the small diameter tip 7.
Since it is blocked by □, the first. Second. Third room 31,3□
, 33 are mutually discontinuous.

Therefore, the first. Second. It is possible to prevent the oils in the third chambers 3□, 32.33 from mixing with each other, and to prevent the dirt in one chamber from entering the other chambers.

For this purpose, for example, as shown in FIG. 7, the reflux oil mixed with dirt is allowed to flow into the third chamber 33, and the overflowing oil is caused to flow into the second chamber 32, and passes through the magnet 20 and strainer 21 to the first chamber 31. If a tank drain device is configured so that the oil in the first room 3□ is supplied with a pump, the garbage in the third room 33, which has a lot of dirt, will be drained into the first room 3□. It is very advantageous because it does not mix with the water.

The present invention is as described above, and if the drain plug 7 is moved to the other side in the longitudinal direction and separated from the valve seat 15 and the sealing surface 14, the first, second and third ports 8°9.11 Since they each open and communicate with the drain ports 13 through the valve holes 6,
1st, 2nd, and 3rd rooms 3. , 32, 33, etc. in a plurality of chambers of the tank 1 can be drained by operating one drain plug 7, making the draining work easy.

In addition, if the lower lane plug 7 is moved to the negative side in the longitudinal direction and the sealing surface 14 is pressed against the valve seat 15, 1. 'The first and third ports 8↓11 and the valve hole 6 are each blocked by the tip, and the second port 9 and the drain port 13 are blocked by the tip.・The second and third ports 8, 9, 11 and the drain board 13 are cut off, and the first, second and third ports
Ports 8, 9゜11 are mutually blocked, and the first, second, and third
The oil in room 3□1,3゜y aa may mix with each other, or
It is possible to prevent trash in one room from entering other rooms.
