Abstract

PURPOSE:To attain the rational piping and to prevent the leakage of gas, etc. of the piping system including a governor, by providing all pressure control mechanisms to a forming body for a primary gaseous pressure room. CONSTITUTION:A gas burner 1 contains a forming body 2 for a primary gaseous pressure room made of die casting aluminum and having an approximately square plane. A gas inflow port 3 is provided at an end face of the body 2. The primary gaseous pressure room 4 is formed contiguously to the port 3, and a diaphragm valve 5 and a hemispherical valve 6 interlocking the diaphragm valve 5 are provided within the room 4. Thus the flown-in gas goes into a secondary gaseous pressure room 9 of a forming body 8 for a secondary gaseous pressure room through a gap formed between the valve 6 and a valve seat 7. A gas outflow port 16 is provided to the body 8.

Description

[Detailed description of the invention] The present invention is used for general gas appliances or gas piping systems,
This invention relates to a gas pressure regulating device.

Conventionally, the configuration of a general gas pressure regulator, a so-called gas governor, was such that the primary gas pressure chamber and the secondary gas pressure chamber were integrally molded using aluminum die-casting, etc., so other piping that was the gas inlet and gas outlet was required. Connection ports with parts are fixed, and when piping is installed, there is no flexibility in the installation direction, and there may be cases where the connecting pipe is unreasonably processed or an excessive load is placed on the governor, resulting in gas leaks, etc. That was one of the factors.

The present invention aims to overcome the drawbacks of the prior art.

The present invention includes a primary gas pressure chamber forming body having a gas inlet and a primary gas pressure chamber communicating with the gas inlet, and a secondary gas pressure chamber communicating with the primary gas pressure chamber and the gas outlet. a secondary gas pressure chamber forming body having a diaphragm, a valve communicating with the diaphragm, and a valve seat for adjusting gas flow rate through a gap with the valve on the side of the primary gas pressure chamber forming body; The structure is such that the secondary gas pressure chamber forming body can be attached to and detached from the secondary gas pressure chamber forming body, and the mounting direction can be changed. The primary gas pressure chamber on the inlet side and the secondary gas pressure chamber on the outlet side are molded separately and can be separated, and the positional relationship between the gas inlet and gas outlet can be changed, making it possible to Increase the number of possible installation directions when installing to gas passages, etc. to avoid unreasonable piping.
This enables rational piping and has the effect of preventing gas leakage in the piping system including the governor.

An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, a gas governor 1 has a primary gas pressure chamber forming body 2 made of aluminum die-casting and having a substantially square plane. The primary gas pressure chamber 4 is provided with a diaphragm valve 6 and a hemispherical valve 6 interlocked with the diaphragm valve 5 to control the pressure of the inflowing gas. The gas flows into the secondary gas pressure chamber 9 of the chamber forming body 8 .

The pressure regulating means in this gas governor 1 is conventionally known, and the primary gas pressure is applied to a diaphragm 6 which is biased by a pressure regulating spring 11 set at a certain strength by a pressure regulating screw 1o. The gas pressure is regulated to a set gas pressure. The pressure regulating spring 11 includes a holding plate 12 and a receiving plate 13. Further, the upper opening of the primary gas pressure chamber forming body 2, that is, the back pressure side of the diaphragm 5, is sealed by a cap 14 and a fixed camp 15, which are press-molded products.

Like the primary gas pressure chamber forming body 2, the secondary gas pressure chamber forming body 8 has a substantially square plane, and the gas outlet 16 is provided on the opposite side to the inlet 3 as shown in FIG. It is being Furthermore, the primary and secondary gas pressure chamber forming bodies 2 and 8 are arranged in a second [5
Fixing screws 1 provided in each corner as shown in 1.
7.18, it can be detachably connected. The image forming body 2.8 of this cut is sealed through the seal gasket 19! Ru. Therefore, for example, if four fixing screws 18 are used, all four fixing screws 18 are set at the same mounting pitch P, and the secondary gas pressure chamber forming body 8 is rotated by 900 degrees, as shown in FIGS. 2, 3, and 4. As shown in the figure, the inlet 3 or the outlet 16 can each be changed in four directions. That is, Figure 2 shows the case where the inlet 3 and outlet 16 are shifted by 1800 degrees and are located on a straight line, similar to Figure 1, Figure 3 shows the case where they are located on the same plane, and Figure 4 shows the case where they are shifted by 90 degrees. Each case is shown below. Alternatively, it is also possible to provide the gas outlet 16 on the left side of FIG. 4 by shifting the gas outlet 16 by 96 in the opposite direction to that shown in FIG.

In the above embodiment, the four fixing screws 18 for fixing the primary gas pressure chamber forming body 2 and the secondary gas pressure chamber forming body 8 were arranged at the same pitch, but six or twelve screws were arranged in a circle. If they are provided at equal intervals on the circumference, their direction can be changed by the number of fixing screws, and they can be further increased or enlarged.

According to the above-mentioned configuration, all the pressure regulating mechanisms are arranged in the primary gas pressure chamber forming body 2, so even if the secondary gas pressure chamber forming body 8 is detachable, the basic gas pressure regulating performance remains unchanged. It is also possible to change direction at will without any need for re-inspection. In addition, the direction change is the primary or secondary gas pressure chamber forming body 2,
This is possible by converting only one of 8, making it possible to share it with many models and preventing cracks in pipes or gas leaks from connections due to unreasonable piping.

As mentioned above, the present invention allows a plurality of combinations of the positional relationship between the gas inlet and the gas outlet in one gas regulating device, and allows the connecting pipe to be the shortest distance in piping. Moreover, it has great effects, such as realizing the miniaturization of gas appliances, etc., which allows for rational piping by avoiding unnecessary piping, unnecessary space, and unnecessary force.
