Description

[Detailed Description of the Invention] This invention relates to a spout valve used, for example, in a heat-retaining container for storing hot water or the like.

Conventionally, this type of spout valve opens and closes the spout by moving an internal valve body based on rotating an operating knob. However, if you open and close the spout frequently, for example when dispensing the required amount of liquid inside the container, you will have to return the operating knob to the closed side each time, and the valve will need to be opened and closed frequently. The problem was that it looked strange.

Therefore, the object of this invention is to provide a spout valve for a heat-insulating container that does not require the operation knob to be returned to its original position every time the spout is opened and closed frequently.

According to this invention, both long and short cam surfaces are formed on the pressing surface of the operation knob that moves the valve body forward and backward by pressing the engaging protrusion formed on the outside of the valve body. When rotated to one side to match the long side cam surface with the engagement protrusion, the operating knob automatically returns to its original position along the long side cam surface, and rotated to the other side to align the long side cam surface with the engagement protrusion. When the surface and the engagement protrusion are matched, the operating knob is engaged and fixed to the end step of the short side cam surface, and the rotational position is fixed. As a result, water injection is automatically stopped on one side based on the automatic return mechanism,
On the other side, continuous water injection takes place based on the fixing mechanism.

In other words, the pressing surface has a long side cam surface and a short side cam surface formed on both sides of the V-shaped neutral position, and normally the engagement protrusion of the valve body engages with the V-shaped low neutral position. The spout is in a closed state, and when the operating knob is rotated toward the long side cam, the engaging protrusion comes into contact with the cam surface, the valve body moves forward, and the water spout is opened.

As soon as the operating knob is released, the engaging protrusion retreats along this cam surface and naturally returns to the low neutral position. Therefore, the spout is immediately closed and the required amount can be dispensed with one touch. When the operation knob is rotated toward the short side cam side, the engagement protrusion engages with the end step of the short side cam surface to maintain the open state of the spout, allowing continuous water injection with the spout open. can be done.

In this way, you can not only open and close the spout, but also rotate the operating knob to the temporary opening side or continuous opening side depending on the pouring operation and pouring volume, and use it freely depending on the usage condition. can.
Particularly suitable for cases that are frequently opened and closed.
It is possible to reliably improve the pouring function of the heat-insulating container.

A screw insertion hole 33 for closely fixing the valve body and an engagement protrusion insertion hole 34 for inserting an engagement protrusion of a valve body to be described later are formed.

The above-mentioned valve body 16 is provided in a small-diameter cylindrical body and is slidably inserted into the above-mentioned valve body 13 with the inner and outer ends respectively protruding, and the inner peripheral surface is provided as a fluid passage. , a liquid introduction part 35 partially cut out to introduce liquid to the circumferential surface of the inner end thereof.
is formed, and a cylindrical liquid outlet portion 36 with an open lower surface at the outer end is vertically provided.

Furthermore, a sealing material 14 is attached to the inner end opening surface 37 of the valve body 16, and this sealing material 14 is attached to the inner end opening surface 37 of the valve body 16.
It opens and closes in a watertight manner in correspondence with the inner end opening surface 39 of. Therefore, the liquid is introduced from the inner peripheral surface of the valve body 16.

That is, as the valve body 16 moves back and forth, the liquid introduction part 35 moves to the inner and outer positions from the inner end surface of the valve body 13, and with the introduction part 35 facing inward, the liquid inside is discharged from the valve body. 16.

Further, the liquid is poured out downward through the liquid outlet 36 and guided to the above-mentioned outlet 29.

Further, an engaging protrusion 15 is protruded from the outer end of the valve body 16, and the valve body 16 is moved forward and backward by engaging with an operation knob to be described later. Further, the outer circumferential surface is formed with a step having a small diameter on the inner end side and a large diameter on the outer end side, and a coil spring 41 is externally fitted on the small diameter side, and the valve body 1
When the valve body 16 is attached to the valve body 13, the coil spring 41 is fitted into the valve body 13 in a compressed state with both ends locked between the outer circumferential step portion 42 and the above-mentioned inner circumferential step portion 20. The body 16 is urged toward the outer end. Note that this biasing force is engaged and fixed by an operation knob to be described later.

The above-mentioned operation knob 17, a disc-shaped knob 43,
It is composed of a small-diameter annular body 44 with a bottom that protrudes from the inside thereof, a large-diameter annular body 45, and a stopper piece 46 that protrudes from an intermediate portion thereof.

A screw insertion hole 47 is bored in the center of the small diameter annular body 44 described above, and a washer 48 and a mounting screw 4 can be inserted therein.

A notch is also formed in a V shape, and a deep low stage part in the center is provided as a neutral position 51, one of both sides thereof is formed as a long side cam surface 52 inclined toward the high stage side, and the other side is also formed on the high stage side. Short side cam surface 5 inclined to
It is formed into 3. Normally, this neutral position 51 engages with the engagement protrusion 15 to position the valve body 16 in the retracting device, and the valve body 16 is in a closed state.
Then, by rotating the operating knob 17 in either direction, the engagement protrusion 15 moves away from the neutral position 51 and moves to the higher cam surface, and based on this, the valve body 1
6 moves forward and the valve body 16 becomes open. At this time, the operating knob 17 automatically returns to the neutral position 51 because it is located on the cam surface with respect to the engagement protrusion 15 on the long side cam side. In addition, on the short side cam side, the engagement protrusion 15 is engaged and fixed to the terminal step of the cam surface, so that
The operating knob 17 does not return to its original position and its rotational position is fixed.

Located between the second stoppers 31 and 32, the operation knob 1
These stoppers 3 rotate based on the rotation of 7.
By regulating the amount of rotation between 1 and 32, the amount of rotation of the operation knob 17 is regulated.

A seal plate 54 is attached to the outer surface of the operating knob 17, and indicates the purpose of continuous water injection or temporary arbitrary water injection in the direction of rotation.

If you want to perform arbitrary water injection based on the display on the seal plate 54 of the spout valve configured as described above, turn the operation knob 17 to the arbitrary water injection side, and based on this, the valve body 16 is advanced and the liquid is discharged. The liquid is poured out from the outlet 29 through the liquid inlet 35 and outlet 36 of the valve body 16. Then, as soon as the operating knob 17 is released, the operating knob 17 automatically returns to its original position. When continuous water injection is desired, the operation knob 17 is rotated to the continuous water injection side, and based on this, the valve body 16 is fixed in the forward position and continuous water injection is performed. After the water injection is completed, the operation knob 17 is returned to its original position to prepare for the next water injection.
