Description

Technical Field

[0001] The utility model relates to the technical field of gas, in particular to a one-to-two concealed box behind a meter. Background Art

[0002] Gas safety is an important issue related to every family and public safety. As an efficient energy source, gas is widely used in many fields such as home cooking and heating. However, accidents caused by gas leaks occur frequently, posing a great threat to personal and property safety. Therefore, it is crucial to ensure the safe and stable operation of the gas system.

[0003] At present, the installation of traditional gas meters on the market usually adopts the method of directly passing two pipes through the wall. This method has obvious defects: first, it is easy to cause gas leakage during the process of pipes passing through the wall, and second, the pipe interface is easy to be backflowed by the external environment such as water or mud, further increasing the risk of gas leakage. The main reasons for these defects include inadequate technology during the pipeline installation process and aging of sealing materials.

[0004] The current solutions are mostly to increase sealing measures and regular maintenance, but these measures are often difficult to completely eliminate the problem. Therefore, there is an urgent need for a two-part concealed box behind the meter to solve the above-mentioned technical defects. Utility Model Content

[0005] The utility model aims to provide a one-to-two concealed box behind a meter to solve the problem of air leakage easily caused by the pipeline passing through the wall in the above-mentioned background technology.

[0007] Preferably, two groups of pipe orifice sleeves are provided at the front end of the shell, and the pipe orifice sleeves correspond to two groups of air pipe ports of the three-way valve respectively. A valve port is opened in the cover plate, and the valve port corresponds to the top valve port of the three-way valve.

[0008] Preferably, inner baffles are provided at the four corners of the rear portion of the shell, outer baffles are provided at both sides of the outer wall of the shell, the inner baffles abut against the inner side of the edge of the installation groove, and the outer baffles abut against the outer side of the edge of the installation groove.

[0009] Preferably, the thickness of the shell is the same as the height of the installation slot.

[0010] Preferably, the box body is a top open component made of metal material, the shell is a plastic component with an open rear end, and the cover is a panel made of surface glass material.

[0011] Preferably, the length of the pipe orifice sleeve is greater than the length of the two groups of tracheal orifices of the three-way valve.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the one-to-two concealed box behind the meter not only avoids air leakage when the pipe directly enters the wall, and prevents water or mud from flowing back into the wall, but also achieves simple assembly and convenient maintenance;

[0013] (1) The concealed box is assembled by arranging a box body, a mounting groove, and a cover plate. When assembled, the shell is aligned with the mounting groove and embedded from top to bottom, the three-way valve is assembled inside the box body, and then the cover plate is assembled on the top of the box body, so that the entire three-way valve is hidden in the box body. The two sets of gas pipe ports of the three-way valve are connected to the two pipelines of the gas meter. The concealed box is installed on the wall to protect the pipeline from penetrating the wall, avoid gas leakage when the pipeline directly enters the wall, play a better pipeline protection role, prevent gas pipeline damage caused by the wall structure, and further ensure the safety of household gas use;

[0014] (2) By providing a shell and a pipe mouth sleeve, a shell is further provided at the front end of the cover plate, and two groups of pipe mouth sleeves are used to protect the two groups of gas pipe ports of the three-way valve respectively. The shell is facing upward, and the buried box is fixed on the wall, so that after the pipe passing through the pipe mouth sleeve enters the wall, the pipeline is divided into two, which can achieve the effect of connection protection, prevent water or wall mud from flowing back into the cover plate, better protect the three-way valve, avoid damage to the gas pipe and gas leakage caused by improper installation, and ensure the safe use of the gas stove valve in harsh environments;

[0015] (3) By providing a shell, a mounting groove, an inner baffle plate, and an outer baffle plate, the cover plate uses an assembled mounting structure, and the three-way valve is fixed in the box body by screws. After the shell and the mounting groove are positioned and engaged, the inner baffle plate abuts against the inner side of the edge of the mounting groove, and the outer baffle plate abuts against the outer side of the edge of the mounting groove. Then, the cover plate is installed on the top of the box body, so that the shell will not easily loosen and fall off from the box body. The assembly is simple, the maintenance is convenient, and it is easy to update or disassemble later, avoiding loosening and falling off during use, and reducing the difficulty and cost of maintenance.
