Description

[Detailed description of the invention] [Industrial application field] This invention relates to a gas regulator connected to a gas tank or the like.

[Prior Art] A conventional gas regulator has a diaphragm 37 between a main body portion 30 and an upper lid 31, as shown in FIG. 4, for example. Main body part 30
An inlet 32 and an outlet 33 are formed therein, and the inlet 32 communicates with a passage 34 . An ear 35 is provided inside the main body portion 30, and a locking arm 36 is attached using the ear 35 as a fulcrum.
A pad 40 for closing the outlet of the passage 34 is provided at one end of the locking arm 36.
Further, the other end of the locking arm 36 is fixed to the center of the diaphragm 37. cap 31
A coil spring 38 is attached between the cap 31 and the diaphragm 37, and the pressure exerted by the coil spring 38 can be adjusted by an adjustment screw 39 screwed into the cap 31.

In such a configuration, gas led from a gas tank (not shown) to the inlet 32 is directed to the passage 3
4, the pressure is reduced within the body portion 34 and the gas is sent via an outlet 33 to a gas appliance (not shown) such as a gas stove. Also, when the pressure within the body portion 34 increases, the diaphragm 37
8, the locking arm 36 swings with the movement of the diaphragm 37, and the pad 40
closes the outlet of passageway 34, thereby closing outlet 33
It is designed to maintain a constant pressure of gas flowing out from the pipe.

[Problems that the invention aims to solve] As described above, conventional gas regulators reduce and regulate the pressure of gas, but their use is limited to this, so they are not suitable for measuring gas volume or detecting gas leaks. A pressure gauge had to be installed separately. Therefore, since the number of connection points increases, there are problems in that installation is time-consuming and the risk of gas leakage increases.

The purpose of this invention is to solve these problems.

[Means for Solving the Problems] The gas regulator according to this invention has a cup-shaped upper lid that has an inlet and an outlet and is open at the bottom, and has a screw hole that communicates with the inlet through a passage. an upper lid formed in the upper part and in which a hole communicating with the inside of the upper lid is formed in the passage; a cup-shaped bottom lid attached to the lower opening of the upper lid; and a cup-shaped bottom lid attached between the upper lid and the bottom lid. A diaphragm, a spring disposed between the diaphragm and the bottom cover, an adjustment screw provided on the bottom cover to adjust the pressure exerted by the spring, one end supported at the center of the diaphragm and the other end connected to the hole. a locking arm supported inside the top lid so that when the pressure inside the top lid increases, the pad swings with the movement of the diaphragm and closes the hole; It is characterized by consisting of a pressure gauge screwed into the hole.

[Function] In the gas regulator according to this invention as described above, in addition to reducing and regulating the gas pressure, the pressure gauge can be used to detect the amount of gas in the gas tank and gas leaks in the piping. It's summery.

[Embodiments] Hereinafter, preferred embodiments of the gas regulator according to this invention will be described in detail with reference to the drawings.

As shown in FIG. 1, a gas regulator 100 according to this invention has an inlet 11 and an outlet 1.
2, a cup-shaped upper lid 1 having a
A cup-shaped bottom lid 2 attached to the bottom opening of
and a pressure gauge 10 screwed into the upper end of the upper lid 1 and integrally attached thereto.

As clearly shown in FIGS. 2 and 3, a screw hole 14 is formed at the upper end of the top cover 1, and the screw hole 14 is connected to the inlet 11 through an L-shaped passage 15.
It is familiar to A vertical hole 16 is formed in the horizontal portion of the passage 15 and communicates with the inside of the top cover 1. The inlet 11 has a screw fitting 13, which is adapted to be attached to a valve of a gas tank (not shown).

A stator 17 is fixed near the vertical hole 16, and a locking arm 1 having a small hole 181 is attached.
8 connects the pin 182 to the stator 17 and the small hole 181.
It is attached so that it can swing by passing it through the. Each end of the pin 182 is held down by a screw 184 to prevent it from coming off. A pad 18 is attached to one end of the locking arm 18.
3 is attached and adapted to close the vertical hole 16. Also, the locking arm 18
The other end passes through a ring-shaped upper portion 192 of the screw 191. The lower end of the screw 191 extends downward and passes through the diaphragm 19 and the disc 193;
These are fixed with nuts 194. A diaphragm 19 is attached between the top cover 1 and the bottom cover 2. A coil spring 1 is installed between the adjusting screw 22 screwed into the screw hole 21 of the bottom cover 2 and the disk 193.
95 is attached, and the screw hole 21 is closed with a cap 23.

Next, in such a configuration, the operation of the gas regulator according to this invention will be explained.

In use, gas enters the L-shaped passage 15 from the gas tank via the inlet 11. Since this passage 15 communicates with the pressure gauge 10, the amount of gas in the gas tank can be known. Gas in passageway 15 flows through vertical holes 16 to gas regulator 100.
, where the pressure is reduced and the outlet 1
2 leaks into gas appliances. When the pressure inside the top cover 1 increases, the diaphragm 19 releases the coil spring 1.
The locking arm 18 swings and moves downward, overcoming the pressure of the pad 18.
3 closes the hole 16 and the gas supply is stopped to prevent further pressure rise. When the gas tank valve is closed, if there is no gas leak, the pressure gauge 1
0 does not change, but if there is a leak in the piping, the pressure will drop, thus making it possible to detect a gas leak in the piping.

It should be noted that the above illustrated embodiment merely shows one embodiment of this invention, and it goes without saying that various modifications can be made without departing from the spirit and scope of this invention.

[Effects of the invention] As described above, the gas regulator according to this invention can not only reduce and regulate the pressure of gas, but also detect the amount of gas in the gas tank and gas leaks in piping. You can also. Also,
Since this gas regulator has a simple structure, it is easy to assemble and can be produced economically. Furthermore, since there is no need to connect the pressure gauge and the gas regulator separately as in the past, the connection work is simplified and the risk of gas leakage due to poor connection is drastically reduced.
