Problems solved by technology

[0002] With the continuous expansion of social needs, if the gas pressure regulating box is not used in daily life, the regional pressure regulating cabinet can only be used to supply gas. However, when this method fails, the gas shutdown range is large, it is difficult to replace, and it can only be repaired online; Moreover, for residential buildings, villas, small industries and other user areas with very small gas consumption, it is difficult to supply gas to the regulator cabinet or the cost of gas supply is very high.

Embodiment 1

[0031] Such as figure 1 As shown, a gas building pressure regulating box provided in this embodiment includes a vertically arranged rectangular box body 1, and the box body 1 is equipped with a pressure regulator 7 and a filter 6 and the output port of the filter 6 Connected to the input port of the pressure regulator 7 in the horizontal direction, the lower input port of the filter 6 is connected to the inlet flange 2 through an inlet ball valve 4 in the vertical direction, and the inlet flange 2 passes through the box body 1 vertically downwards , the output port at the lower end of the pressure regulator 7 is connected to the outlet flange 3 through a deflation elbow ball valve 8 and an outlet ball valve 10 in the vertical direction, and the outlet flange 3 passes through the box body 1 in the vertical direction; wherein:

[0032] The inlet ball valve 4 is threadedly matched with the filter 6 and the inlet flange 2 respectively, between the deflation elbow ball valve 8 and ...

Embodiment 2

[0034] The structure of the gas building pressure regulating box in the present embodiment is the same as that in Embodiment 1, and the using method of the gas building building pressure regulating box of the present embodiment is carried out according to the following steps:

[0035] Step (1): Install the surge tank at the bottom of the box body 1 at a height of 1.0m from the ground;

[0036] Step (2): After the installation is completed, connect the pressure regulating box into the pipeline system through the inlet flange 2 and the outlet flange 3;

[0037] Step (3): Carry out the sealing performance test, enter the inert gas neon gas into the pipeline system at a pressure of 3Mpa, keep it for 30 minutes, if there is no leakage, then reduce the pressure to 0.05Mpa, keep it for 15 minutes, if there is no leakage If there is no gas phenomenon, continue to step (4);

[0038] Step (4): After completing the sealing performance test, open the inlet ball valve 4 at an opening of 5...

Embodiment 3

[0040] The structure of the gas building pressure regulating box in the present embodiment is the same as that in Embodiment 1, and the using method of the gas building building pressure regulating box of the present embodiment is carried out according to the following steps:

[0041] Step (1): Install the surge tank at the bottom of the tank 1 at a height of 1.2m from the ground;

[0042] Step (2): After the installation is completed, connect the pressure regulating box into the pipeline system through the inlet flange 2 and the outlet flange 3;

[0043]Step (3): Carry out the sealing performance test, enter the inert gas argon into the pipeline system at a pressure of 4Mpa, keep it for 40 minutes, if there is no leakage, then reduce the pressure to 1.0Mpa, keep it for 18 minutes, if there is no leakage If there is no gas phenomenon, continue to step (4);

[0044] Step (4): After completing the sealing performance test, open the inlet ball valve 4 at an opening of 8% / min, an...

Abstract

The invention discloses a gas building pressure regulating box which comprises a vertically arranged rectangular box body. A pressure regulator and a filter are arranged in the box body in a hidden mode. An output port of the filter and an input port of the pressure regulator are connected in a communicated mode in the horizontal direction. A lower-end input port of the filter is connected with a suction flange through an inlet ball valve in the vertical direction. The suction flange penetrates through the box body vertically and downwardly. A lower-end output port of the pressure regulator is connected with a discharge flange through a deflation curved spit ball valve and an outlet ball valve sequentially in the vertical direction. The discharge flange penetrates through the box body in the vertical direction. The inlet ball valve is in screw-thread fit with the filter and the suction flange respectively. The deflation curved spit ball valve is in screw-thread fit with the pressure regulator and the outlet ball valve. The outlet ball valve is in screw-thread fit with the discharge flange. The invention further provides a using method of the gas building pressure regulating box. The pressure regulator is arranged in the gas building pressure regulating box, so that the pressure at an outlet is stable, and reset is more convenient; maintenance is convenient, dismantling is simple, and cost is lowered.

Description

technical field [0001] The invention relates to a pressure regulating box for a gas building, in particular to a pressure regulating box for a gas building and a method for using the same. Background technique [0002] With the continuous expansion of social needs, if the gas pressure regulating box is not used in daily life, the regional pressure regulating cabinet can only be used to supply gas. However, when this method fails, the gas shutdown range is large, it is difficult to replace, and it can only be repaired online; Moreover, for residential buildings, villas, small industries and other user areas with very small gas consumption, it is difficult to supply gas to the regulator cabinet or the cost of gas supply is very high. Therefore, the present invention provides a gas pressure regulating box and its use method here to solve the above-mentioned problems. Contents of the invention [0003] The technical problem to be solved by the present invention is, aiming at ...
