Description

Household gas valve {AAAAA}

The present invention is to provide a gas valve for the gas, particularly to be able to operate the valve for a long time with a small power.

In the conventional vertically movable electromagnetic valve, the current flowing through the solenoid coil had to be large, so that the power consumption was not only high, but also during the manufacture, the design and manufacturing conditions for matching the mechanical coupling such as the spring tension, the compression force, and the strength of the permanent magnet were used. There was a lot of difficulty.

In addition, in the motor method that must be installed in order to open the valve in the existing gas pipe, the spark by the brush in the case of DC motor can not be used, and stamping motor is expensive, there was a problem in economic efficiency.

The present invention has been devised in view of the above-described conventional problems, and can be applied to an electronic gas meter while being able to use a single battery for many years, and can exhibit a strong force even in a small structure without a brush-less structure with low power consumption. A rotary body rotating at right and left 170 ° by the force of an electromagnet to provide a valve, a rotary plate for converting the rotational force of the rotary body to a vertical reciprocating motion, and a valve rod opened and closed from the left side of the rubber valve while vertically connected to the rotary plate; It is solved by an auxiliary hole for reducing the initial driving force by the pressure at the time of opening and closing the rubber valve.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a T-shaped tube in which the casing is a casing (Casing) in the drawing according to one embodiment of the present invention, the screw length is formed at each end of the gas supply pipe or gas connection pipe not shown Being able to connect is like a notification.

In the inside of the T-shaped tube 1, a conical rubber valve 2 having a hole 2 'formed at the center thereof is inclined at an inner circumference of the T-shaped tube 1 as shown in cross-sectional views in FIGS. The jaw 28 can be seated in reverse. In the hole 2 'which is drilled in the center of the conical rubber valve 2, a horizontal hole 11 is formed in the head, and an annular groove 11' is formed at one end and a pin 11 'is formed at the end. The pin 11 ′ of the rod 10 is to be crushed, and the valve rod 10 is inserted through the hole 24 of the auxiliary piece 9 and the hole 25 of the cover 8 while rubber It is inserted through the conical cap (5) adhered to the connecting washer (6) fixed to the valve (2) and the 'C' ring is inserted into the groove groove (11 ') of the valve rod (10) The coil spring 3 is held between the rubber valve 2 and the 'C' ring.

Meanwhile, the horizontal holes 11 of the head of the valve rod 10 protruding out of the holes 24 and 25 of the cover 8 and the 'a' shaped auxiliary piece 9 rotate through the bolts 14. The hole 16 of the rotating plate 12 is fitted to the rotating shaft 17 of the bidirectional rotating body 18, which is a solenoid, and is driven in both directions. In addition, the bidirectional rotating body 18 is fixed by the screws 22 to the hole 26 of the cover 8 by the '22' shaped auxiliary surface 9 by the screws 22 and the bolts. The bidirectional rotating body 18 is fixed through the hole of the auxiliary surface 9 by the reference numeral 20. In Fig. 1, reference numeral 15 denotes a protrusion formed on the outer circumference of the rotating disc 12, and is 170 ° or more to the left and the right by supporting jaws 9 and 19 'formed on the outer circumference of the bidirectional rotating body 18. The rotation is impossible.

3 and 5, an explanatory view of the bidirectional rotating body 18 is shown. That is, in FIG. 3, M is a permanent magnet representing a rotor of the bidirectional rotating body 18, and F is a stator of the bidirectional rotating body 18, in which coils L1 and L2 are connected in series to change electrodes. As the power is supplied, the same polarity of DC motor is to make the right turn or the left turn by receiving the 180 ° rotational force by repulsing or sucking the copper poles. However, if 180 ° is rotated, since arbitrary control is not possible when reverse rotation is made, only 170 ° is rotated by the external stroke in this embodiment.

In other words, the upper and lower outer sides of the bidirectional rotary body 18, the stop jaw (19, 19 ') is fixed to the point 170 ° and the rotation is fixedly fixed through the hole 16 in the rotary shaft 17 of the bidirectional rotary body 18 The projections 15 protruding from the outer top of the disc 12 prevent the rotation disc 12 from rotating further by the stoppers 19 and 19 '.

That is, when current flows through the coils L1 and L2 connected to the stator F of the bidirectional rotating body, the rotor M, which becomes a permanent magnet, rotates 180 ° in the direction of the arrow as shown in FIG. It rotates in the suction state of the above, but the stopper (19, 19 ') by 170 ° or more can not rotate. This is a state in which the rubber valve 2 blocked the guide groove 28 as shown in FIG.

In the above state, as shown in FIG. 5, when current flows in the opposite direction to FIG. 3 through the coils L1 and L2 of the stator F, the rotor generated as the magnetic pole generated by the stator F changes. The magnetic poles of F) and the stator become the NN and SS poles and are repelled to rotate in the direction of the arrow as shown in Fig. 5, so that the magnetic poles of the stator F and the rotor M are attracted to each other. However, as the rotor rotates 170 ° as described above, the rotating plate 12 fixed to the rotating shaft 17 of the rotor F also rotates together. However, since it is adhered to the screw hole 13 of the rotating plate 12 by the bolt 14 through the horizontal hole 11 formed in the head portion of the valve rod (10) by a high-pressure gas pressure as shown in FIG. In the state in which the inclined jaw 28 is blocked by the high valve 2, the horizontal hole 11 formed in the head of the valve rod 10 is connected to the screw hole of the rotating plate 12 by a bolt l4. When the rod 10 is lifted up, while the rubber valve 2 is pressed through the coil spring 3 with the 'C' ring, the hole 2 'of the rubber valve 2 is blocked by the pin 11'. At first, when the pin 11 'formed at the tip of the valve rod 10 rises from the hole 2', the high pressure gas falls into the above-described hole 2 'of the valve 2 and is released from the high pressure. State and the above-mentioned valve rod 10 rises and the 'C' ring fixed to the valve rod 10 reaches the inner circumferential surface above the semi-conical cap 5, this time the cap 5 described above. 'C' While pulling up along this time, by pulling up the connecting washer 6 fixed on the upper surface of the rubber valve (2), the rubber valve (2) is separated from the guide groove (28) and becomes a state as shown in FIG. It is open.

In this state, when the current of different polarity is applied to the coils L1 and L2 of the stator F again, the bolt 14 fitted into the screw hole 13 of the rotating plate 12 is turned into the valve rod 10. When the valve rod 10 is lowered through the ileal hole 11 formed in the head portion, the rubber valve 2 descends to block the inclined jaw 28 and the valve rod 10 descends. As the pin 11 'formed at the tip of the valve rod 10 is blocked by the hole 2' of the rubber valve 2, the high pressure of the inlet presses the upper layer of the rubber valve and continues to descend. The 'C' ring (4) of the valve rod 10 is to press the coil spring (3) to cross the gas pressure more firmly. If it is to be opened again in the above state, the bolt 14 of the rotating disk 12 is raised through the horizontal hole 11 forming the head of the valve rod 10, the end of the valve rod 10 By opening the hole 2 'of the rubber valve 2 by the formed pin 11', passing the gas pressure to release the pressure and then raising the rubber valve from the induction groove 28 in the state where there is almost no pressure. (2) is to be isolated, and on the contrary, in the case of the cross, the rubber valve (2) is first blocked by the inclined jaw (28), and then the rubber valve (2) by the pin (11 ') formed at the tip of the valve rod (10) It is possible to reliably cross-open by closing the hole 2 'so that the gas pressure evenly spreads over the rubber valve 2.

6 is an exploded perspective view illustrating another embodiment of the present invention, and FIGS. 7 and 8 are cross-sectional views of the assembled state by explaining the operation of the embodiment. In the drawings of the other embodiment, the same reference numerals are assigned to the parts having the same function as that of FIG.

That is, instead of the 'T' shaped pipe as shown in FIG. 1 in FIGS. 6 to 8, the head portion which fixes the two-way rotating body 18 to the side of the tube and forms the horizontal hole 11 of the valve rod 10 is shown. The inner wall of the pipe 100 is moved up and down along the guide groove 101 concave, and the turntable jaw 102 is formed so that the rotating plate 12 does not rotate more than 170 degrees in front of the bidirectional rotating body 18 and the rotating plate described above. The bar 103 is protruded into the screw hole 13 of (12) so as to be inserted into the horizontal hole 11 of the valve rod 10 mentioned above.

In the above-described embodiment, the horizontal hole 11 formed in the head of the valve rod 10 is inserted into and lifted up through the guide groove 101 recessed in the inner circumferential surface of the pipe 100, and the bar 103 is lifted. The rotating disc 12 fixed to the protrusion is connected to the rotating shaft 17, the bidirectional rotary body 18 is screwed through the hole 106 of the bidirectional rotary body 18 and the rubber packing 104 When screwed into the hole 107 and the screw hole 106 formed on the side surface of the pipe 100, it becomes the structure similar to sectional drawing like FIG.7 and FIG.8.

Therefore, as described above, by energizing the bidirectional rotating body 18 with different polarity, the rotating shaft 17 of the bidirectional rotating body 18 is rotated 180 ° to the left or the right side. By suppressing the rotation of more than 170 ° as described above it is easy to rotate left or right as the polarity of the magnetic pole changes according to the polarity of the next power source. As such, the rubber valve 2 provided at the end of the valve rod 10 becomes the inclined jaw 28 when the bar 103 protruding from the rotating plate 12 is rotated and downward as shown by the arrow in FIG. The pin 11 'formed at the end of the valve rod 10 blocks the hole 2' of the rubber valve 2 and crosses by the gas pressure reliably while displacing the above-mentioned. By supplying power to the bidirectional rotor 18 with different electrodes, the NN and SS poles repel from suction between the NS poles until now, so that the rotation disc 12 rotates in the opposite direction, so that the bar 103 is rotated in FIG. As it rises in the direction of the arrow, the valve rod 10 is raised. Therefore, by opening the hole 2 'of the rubber valve 2 blocked by the pin 11' formed at the end of the valve rod 10, the rubber valve 2 is released by gas pressure to release the valve 2 from the valve rod 10. Following the rise of), it rises easily and opens.

As described above, according to the present invention, the pin 11 'formed at the end of the valve rod 10 opens the hole 2' punched in the rubber valve 2, thereby applying or releasing the gas pressure. It is possible to open and close the valve, the rotation disc by the stop jaw or ring bump on the bidirectional rotating body to prevent the rotation more than 170 ° to be able to easily rotate in the reverse direction during the next stage of rotation. In addition, the electrode is connected to the fixed electrode of the bidirectional rotating body by rotating the rotating body which becomes a permanent magnet to the left or the right side through a horizontal hole formed in the head portion of the valve rod through a bolt or bar protruding from the rotating disc. By raising and lowering the rubber valve, it is not only effective to ensure the lap effect but also the power supply to the bidirectional rotating body can change the magnetic pole of the stator even with a weak power supply, so it can be used for a long time even with low power. As it is a noid type, there is the characteristic that there is no danger of the fire by the flame.
