The gas storage detecting device includes a connecting main pipe 11 detachably connected to a gas drum 10 , and a voltage regulator 12 disposed at the connecting main pipe 11 . And a pressure gauge 13 disposed between the gas cylinder 10 and the regulator 12, the user can understand the gas cylinder 10 by viewing a pointer 131 of the pressure gauge 13 Gas inventory.

Referring to FIG. 2, another gas storage detecting device is provided. The gas storage detecting device includes a connecting main pipe 15 detachably connected to a gas drum 14 , and a side disposed on the connecting main pipe 15 and having a A quick connector seat 16 of the reed switch 161, and a quick connector 17 connected to a backup gas drum 18 and removably inserted into the quick connector housing 16 and having a magnetic member 171.

When the gas of the gas drum 14 is used up, the user needs to connect the quick joint 17 of the spare gas drum 18 to the quick joint 16 at this time, and the magnetic member 171 touches the reed switch 161 and triggers a The induction auto-transmitter (not shown) transmits a signal to a dial-up host (not shown), and the dial-up host automatically dials the gas dealer. After the gas operator integrates the information of each user, the route for distributing the gas can be planned.

The first type of gas detection and storage device is known, although the gas inventory can be clearly displayed from the pressure gauge 13, but generally for safety reasons, the gas More than 14 barrels will be stored in the balcony or outdoor, which is more convenient to check at the time. Therefore, if the user does not pay attention to the gas storage of the gas barrel 14 from time to time, it may happen that the bath is washed half or cooked. In half, and the gas has run out of trouble.

However, the second type of gas detecting and storing device can be automatically dialed to the gas supplier when the user picks up the spare gas bucket 18, but the user needs to store a spare gas bucket 18, which not only takes up space but also increases Potential security risks, after the gas is used up, the user still has to pick up the spare gas bucket 18 and wait for the gas dealer to deliver another new spare gas bucket, which is not in line with current user habits. Moreover, after the gas industry integrates the information of each user, it still needs to confirm the delivery time with the user one by one. If the user misses the contact number of the gas supplier, the user may run out of the backup gas while waiting for the delivery time to be confirmed. It is necessary to contact the gas dealers on their own. Instead, they need more round-trip calls. In addition, the cost of setting up automatic dialing equipment is high, and the general user's willingness to pay is low. In addition to the general gas bucket 14, the gas industry needs extra. The maintenance and safety inspection costs of the spare gas drum 18 are greatly increased, and the operating cost is greatly increased.

Therefore, the object of the present invention is to provide a gas fitting capable of low-voltage interruption in a low-cost and simple operation, and capable of reminding the user of the gas storage condition in a barrel of gas.

Therefore, the gas fitting capable of being interrupted at a low pressure comprises a body, a shut-off valve, and a releasing unit.

The body includes a flow path having an inlet and an outlet for gas to flow in and out, respectively, and a valve port between the inlet and the outlet.

The blocking valve includes a valve plug member and a resilient member that pushes the valve plug member to close the valve port. When a pressure value of the gas flowing in from the inlet is greater than a predetermined value, the valve plug can be pushed The piece exits the valve port so that gas can flow out of the outlet through the valve port.

The release unit is disposed on the body and includes an actuating lever movable relative to the valve plug member, the actuating lever being operable to move the valve plug member away from the valve port.

The utility model has the beneficial effects that the valve plug can block the valve port when the pressure value of the gas is lower than the preset value, so that the gas cannot flow out from the inlet to the outlet through the valve port. At this time, by using the actuating rod to push the valve plug, the gas can flow out to the outlet through the valve port, so that the user can still have a certain amount of gas in the barrel gas. And knowing that the gas is about to be used up, so that users can contact the gas dealer to distribute another barrel of gas, so that the convenience of using the barrel gas can be greatly improved.

The foregoing and other technical aspects, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 3, FIG. 4, and FIG. 5, a first preferred embodiment of the present invention is capable of connecting between a gas barrier switch 100 and a gas barrier 200. The broken gas fitting comprises a body 2, a shutoff valve 3, a release unit 4, and a voltage regulator 5.

The body 2 includes a first-class track 21 and two oppositely disposed blocks 22. The flow path 21 has an inlet 211 and an outlet 212 for gas inflow and outflow, and a valve port 213 between the inlet 211 and the outlet 212. In the first preferred embodiment, the inlet 211 is used to connect the gas drum switch 100, and the outlet 212 is used to connect the gas appliance 200. The body 2 is integrally formed by casting.

The blocking valve 3 includes a valve plug member 31 received in the flow passage 21, a resilient member 32 that pushes the valve plug member 31 to close the valve port 213, and is screwed to the body 2 and pressed The fine adjustment member 33 is abutted against the elastic member 32. In the preferred embodiment, the valve plug member 31 is a ball, and the elastic member 32 is a compression spring. When a pressure value of the gas flowing in from the inlet 211 is greater than a predetermined value, the valve can be pushed. The plug member 31 exits the valve port 213 such that gas can flow out of the outlet port 212 via the valve port 213.

The releasing unit 4 is disposed on the body 2 and includes an actuating lever 41 movable relative to the plug member 31, and an operating member 42.

The actuating rod 41 is movably disposed through the body 2 and is operable to move the valve plug member 31 away from the valve port 213.

The operating member 42 is connected to one end of the actuating lever 41 opposite to the plug member 31 and outside the body 2, and has two hooks 421 which are oppositely disposed at opposite ends. Wherein, the actuating rod 41 and the elastic element 32 are respectively Located on the opposite side of the valve plug member 31, the actuating lever 41, the plug member 31, and the elastic member 32 are arranged along an axis L and are movable along the axis L.

The regulator 5 communicates with the flow channel 21 and is located between the shutoff valve 3 and the outlet 212 for stabilizing the flow of gas into the gas appliance 200 to avoid danger. Among them, the regulator 5 is not the main technology of the present invention, so it will not be described in detail here.

Referring to FIG. 5 and FIG. 6 , in use, the gas operator can rotate the fine adjustment member 33 to adjust the force of the elastic member 32 on the valve plug 31 to set the preset value and then provide the same to the user. That is, if the gas operator first sets the gas pressure value of the preset value of 5 kg, the valve plug 31 can be pushed if the pressure value of the inflowing gas is higher than 5 kg. And exiting the valve port 213, allowing gas to flow out from the outlet 212 via the valve port 213, as shown by the arrow in FIG. 5, if the pressure value of the inflowing gas is less than 5 kg, the valve plug When the thrust pushed by the gas is insufficient to resist the elastic force generated by the elastic member 32, the elastic member 32 pushes the valve plug 31 against the valve opening 213, as shown by the imaginary line in FIG. 5, so that the gas cannot pass through the valve. The valve port 213 flows out from the outlet 212. At this time, the user can know that the gas storage in the drum gas is low, and the user needs to press the operating member 42 downward to move the operating rod 41 downward along the axis L to push the valve plug 31 upward. Leaving the valve port 213 and fastening the hooks 421 of the operating member 42 to the blocks 22 of the body 2 by rotating an angle, the actuating lever 41 is restrained from being The elastic force of the elastic member 32 is pushed up and moved upward, as shown in FIG. 6. At this time, the gas can be further flowed out from the outlet 212 via the valve port 213 for the user to continue. After continued use, the user can then call the gas dealer to arrange for the delivery of another barrel of gas to avoid the use of gas after the gas is used up.

Referring to FIG. 7, a second preferred embodiment of the present invention is capable of low-voltage interrupted gas fittings. The content of the second preferred embodiment is substantially the same as that of the first preferred embodiment, except that the releasing unit 4 further includes a setting. The transmitter 43 of the body 2 includes a switch 431 that can be triggered by the operating member 42 and a wireless transmitting component 432 that is electrically connected to the switch 431. In operation, when the user presses the operating member 42 downward, as shown by the imaginary line in FIG. 7, the lower edge of the operating member 42 can be triggered to the switch 431 to allow the wireless transmitting component 432 to send out a wireless device. The wireless signal can be transmitted to a servo host (not shown) of the gas dealer through an automatic dialing device (not shown) such as the second, so that the gas operator can instantly grasp the state of use of the user gas. Or it is transmitted to the receiving prompter as disclosed by the applicant in M441098, and the user actively contacts the gas dealer.

Referring to FIG. 8 , a third preferred embodiment of the present invention is capable of being connected between a gas barrier pump 100 and a gas damper device 300 . The gas damper device 300 has a The voltage regulator 301 is substantially the same as the second preferred embodiment except that the low-voltage interrupted gas accessory does not include the second preferred embodiment. The regulator 5 is described (see Figure 4). An inlet 211 of a body 2 of the low-voltage interrupted gas fitting is used to connect the gas drum switch 100 to an outlet 212. The gas voltage regulator 300 has a voltage regulator 301. The third preferred embodiment does not need to change the commercially available gas drum switch 100 and the gas voltage regulator 300. It can be used directly between the gas barrel switch 100 and the gas voltage regulator 300.

According to the above description, the gas fittings capable of being interrupted at low pressure have the following advantages and effects:

1. The valve plug 31 can block the valve port 213 when the pressure value of the gas is lower than the preset value, so that the gas cannot flow out from the inlet 211 to the outlet 212 via the valve port 213. At this time, after the valve plug 31 is pushed by the actuating rod 41, the gas can be discharged to the outlet 212 through the valve port 213, so that the user can still store a certain amount of gas in the barreled gas. Under the circumstance, the news that the gas is about to be used up, so that the user can contact the gas dealer to distribute another barrel of gas, can greatly improve the convenience of using the gas in the barrel.

2. By the cooperation of the blocks 22 and the hooks 421, the operating member 42 can be fixed and fixed after being rotated by an angle, which is relatively simple and convenient to operate.

Third, the user can use this new type, that is, it is not necessary to store a spare barrel of gas in the home, but it can virtually divide the full volume of a barrel of gas into one large and one small quantity, and generate a prompt when the large amount is used. The role, and still small quantities can be used continuously, so that the possibility of potential dangerous events can be greatly reduced to improve the safety of residence.

However, the above description is only a preferred embodiment of the present invention, and when it is not possible to limit the scope of the present invention, that is, the patent application of this new type The simple equivalent changes and modifications made by the scope and new descriptions are still within the scope of this new patent.
