Description

Valve protection cover for indoor and outdoor gas pipes

In some cases, city gas pipes and LPG pipes are piped into or out of the walls of houses, apartments, and mall buildings. Fuel gas liquefied gases, such as city gas and LPG, are explosive and are dangerous to life. The gas valve is installed on the pipeline in consideration of the safety of the gas pipe.

However, the gas valve is exposed to anyone, so it may be out of reach of children, or the anxiety of accidentally being manipulated by an outsider approached with impure intentions. It would be the same for everyone to tighten.

In order to eliminate such anxiety, there is an example in which a gas valve on a gas pipe is covered with a cover to prevent unauthorized manipulation of others. The conventional gas valve protective cover is large in appearance since it is manufactured in consideration of the case where the position of the valve handle is changed to the closed position. The large appearance of the cover is considered to be a high material cost first, and in the case of steel, the soldering parts are large, and the welding cost and the power cost are also high.

In addition, since the drill stabilizes the cover by drilling a nail hole with a power drill on the wall of the building adjacent to the gas valve, the perforation noise is severe, and if the perforation position is slightly selected, the posture of the cover is unsightly and damaged. It is also difficult to remove the cover.

In addition, it was not possible to visually check whether the valve was locked without opening the front cover.

The purpose of the present invention is to lock the closed valve with the front cover, and to minimize economics and increase the economic efficiency, it can be installed and stabilized without scratch on the building wall, and it is easy to check the opening and closing state of the valve without opening the cover indoor or outdoor. It is to provide a cover for protecting the valve of the gas pipe.

The present invention forms a flat U-shaped tube groove with a rear flap on the upper and lower surfaces of the main body with the front and back fully open and easy to cover and peel off the gas pipe, and the front of the main body can be covered by a hinged front cover. In the main body, a semicircular fixing band is attached to the outer surface of the gas pipe or the flange thereof, and the semicircular detachable band is fastened to the fixing band, and the handle hole for trapping the handle of the valve is locked at the free end of the front cover. In addition, it provides a cover for protecting the valve of the external gas pipe.

1 and 2, the valve protection cover A of the gas pipe is attached to the front cover 2 by the hinge shaft 3 in front of the main body 1, the main body 1 is closed all around the front and rear It has the shape of a large open tube, and its height has dimensions to cover the flange of each gas pipe flanged at the inlet and outlet of the valve at one time. The front cover (2) is equipped with a lock device (6) which is locked to the main body (1) when closed on the free end side.

A flat U-shaped tube groove 4 is formed in the width center of the top plate and the bottom plate of the main body 1 with the back open. The tube groove 4 of the top plate has a gas pipe connected to the outlet end of the valve, and the tube groove 4 of the bottom plate has a width that can be slightly covered with the gas pipe connected to the inlet end of the valve. It has a length that is slightly larger than the maximum distance of the gas pipe from the wall surface so that it can be completely covered on the gas pipe, and when the cover A is put on, the intention of dismantling is also intended. Reference numeral 10 in FIG. 2 denotes a hinge for attaching the front cover 2. Until now, it is known.

The present invention perforates the handle hole (5) for locking the handle of the valve locked in the side of the free end of the front cover (2) in the valve protection cover (A) of such a gas pipe, the body 1 In Fig. 2, as shown in Figs. 2 to 4, a fixing band 7 for fixing the cover to the gas pipe or the gas pipe connection flange is fixed and the removable band 8 is fastened to the fixing band 7.

The handle hole 5 is centered on the horizontal line passing through the axial center of the valve handle, the height is formed to have a little margin than the width of the valve handle and the outer end is completely thin so that the front cover 2 can be opened and closed without difficulty. Make sure

The fixed band 7 and the detachable band 8 paired with this are divided into half, and the fixed band 7 is fixedly attached to the internal place of the main body 1 and the detachable band 8 is fixed to the fixed band 7. To fit the band (7) to fasten both ends with screws 10 to achieve a sense of unity.

In the example shown in Figs. 2 and 3, the fixing band 7 is shown attached to the position to bind the gas pipe up and down the valve side. 7) Attached so as to surround the accommodating surfaces of the flanges (F, F ') and the removable band (8) around the remaining accommodating surfaces of the flanges (F, F').

When the cover A is covered by the valve V of the gas pipes C and C 'piped along the building wall B, it is shown in the figure below. The method of attaching the cover A is as follows. Operate the locker (6) to open the front cover (2), remove the screw (9), remove the detachable band (8), and place the pipe groove (4) in the gas pipe (C, C) of the upper and lower flanges (F, F '). , C ').

When the back surface of the main body 1 touches the building wall B, the fixing band 7 surrounds the first half of the outer circumferential surface of the gas pipes C and C 'or the first half of the outer circumferential surface of the flanges F and F'. And since the top plate of the main body 1 is mounted on the upper flange F and the bottom plate is under the lower flange F ', the main body 1 as well as the cover A as a whole may fall out of the valve V. There is no.

Put the cover (A) on, push the removable band (8) behind the gas pipes (C, C ') or the flanges (F, F'), align with the fastening hole of the fixing band (7), and then screw (11). ) And fasten. At this time, the handle (H) can only cover the main body 1 in the vertical position with the valve (V) open. If the handle H 'stays in the horizontal position when the valve V is closed, the main body 1 is caught and cannot be covered.

The cover (A) is stabilized and the handle (H ') is turned horizontally to lock the valve (V) and close the front cover (2). When the front cover 2 is closed, the handle hole 5 deflects the handle H 'so that it can be completely closed. When the front cover (2) is closed in this state and the lock device (6) is locked, the handle (H ') is trapped tightly in both the top and bottom of the handle ball (5). It is safe as long as the front cover 2 is not opened with the lock device 6.

Dismantling of the installed cursor (A) is to open the front cover (2), loosen the screw (10) to remove the removable band (8) and proceed in the order of lifting.

As described above, the valve protection cover of the indoor and outdoor gas pipes of the present invention has a fixing band for fixing the body to the gas pipe side in the main body, and a fixing band is fastened to the fixing band, and the front cover is horizontal when the valve is closed. It is configured to close the valve handle in a position so that it can be closed smoothly, and the cover can be stabilized without drilling a nail into the wall by the band, so it is very easy to attach the cover, it takes less time and installation cost, and the cover is quietly Can be pasted.

In addition, if the front cover is closed and locked while the valve is closed, the handle is locked in the handle hole and can not move, so that the user may be distracted from the risk of operating the valve by anyone other than the gas handler.

In addition, since the valve handle is locked, a substantial portion of the free end is exposed to the outside of the handle hole. Therefore, the width of the body and the front cover are reduced by the dimension of at least the exposed handle part, which is economical due to material saving and reduction of the welding area. Along with the benefits it adds to the beauty of the small.

In addition, when the handle of the valve comes out of the handle hole of the closed front door, it can be seen that the gas valve is locked, so it is easy to check the safety of the gas valve without opening the front cover.
