Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control panel for a gas facility, and more particularly to a control panel for a gas facility installed for performing various operations and monitoring in a gas filling facility or the like.

[0002]

2. Description of the Related Art For example, equipment for filling a high-pressure gas container (cylinder) with various gas products such as oxygen gas, nitrogen gas, and argon gas requires a pretreatment such as gas release performed before filling the cylinder with gas. As a facility for monitoring the pressure and temperature when filling the gas and the actual gas, it has a pressure gauge and a display unit that displays the flow state of the gas, etc., and an operation unit for starting and stopping each operation A control panel having the same is installed.

Usually, in a large-scale filling facility, a control panel is designed and manufactured after the layout of the entire filling facility is determined, so that a control panel having an optimal configuration corresponding to each facility can be manufactured and installed. In a relatively small filling facility, a plurality of standard control panels may be manufactured in advance as general-purpose products in order to reduce costs.

[0004]

However, inside the control panel, there are housed gas pipes to which various valves for controlling the gas flow, pressure sensors, and the like are mounted. It is necessary to connect to the piping at the installation site. These gas pipes are made of rigid metal pipes so that they can withstand the high pressure state during gas filling and the vacuum state during gas release. Unlike those having a control panel, changing the piping layout after manufacturing the control panel involves bending, cutting, welding, and the like of the metal piping, and therefore cannot be easily performed.

Therefore, even in the case of general-purpose products, after the connection direction of the external piping is determined according to the installation location,
Some changes were made to the layout of the internal piping, and the final connection to the external piping was manufactured.
In addition, it is conceivable that the directionality of the control panel may be eliminated by taking out the piping from the back or the top plate, but when installing indoors, taking out the piping becomes difficult due to the positional relationship with the partition wall and ceiling. Sometimes.

[0006] Because of this, most control panels for gas equipment are made to order, so that the process management and the procurement of parts and components in a production factory become troublesome.
The production period (delivery time) is also long, which is a factor of cost increase.

Accordingly, the present invention provides a control panel for gas equipment which can be installed at an arbitrary position by making it possible to select a connection direction of an external pipe with respect to an internal pipe of the control panel, and which can reduce costs by centralized production. It is intended to provide.

[0008]

In order to achieve the above object, a control panel for gas equipment according to the present invention is provided with a display unit and an operation unit on a front surface of a housing containing a gas pipe provided with devices such as a pressure gauge and a valve. In the control panel for gas equipment having a section, the internal pipe installed in the housing and connected to the external pipe is branched into a plurality of pieces, and the distal ends of the branch pipes are respectively installed on the wall surfaces of the housing, and The portion is closed by a detachable closing member.

Further, each end of the branch pipe is arranged near the inner wall surface of the housing, and a pipe insertion hole for connecting an external pipe to the branch pipe is formed in a wall portion corresponding to the end of each branch pipe. Further, the pipe insertion hole is closed by a detachable closing member.
