Description

Technical Field

[0001] The utility model relates to the technical field of control boxes, in particular to an air source control box. Background Art

[0002] The gas source control box is a device used to control the pressure, flow and direction of gas. It is usually composed of one or more valves, filters, pressure reducers, flow meters, etc. to achieve precise control of the gas. The gas source control box is widely used in industrial production, such as machinery manufacturing, metallurgy, chemical industry and other industries. The main function of the gas source control box is to provide a stable and reliable gas supply to meet the needs of various industrial equipment. It can convert high-pressure gas into low-pressure gas and control the gas pressure and flow by adjusting valves and pressure reducers. In addition, the gas source control box can also remove impurities and moisture in the gas by installing filters to ensure gas quality.

[0003] When the existing gas source control box is connected to the external gas hose, a hose welding machine is usually used to soften the inner and outer walls of the hose and then splice them. This connection method is usually a one-time connection during the connection process. Once cracks appear at the connection later, it will affect gas leakage and be inconvenient for maintenance. In view of this, we provide a gas source control box. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: an air source control box, comprising a box body 1, an air source pressure regulating filter 2 is fixedly connected to one side of the top of the inner wall of the box body 1, and a group of first L-shaped ventilation pipes 3 are fixedly connected to both sides of the outer wall of the air source pressure regulating filter 2, a plurality of electronic reversing valves 4 are fixedly connected to the bottom of the inner wall of the box body 1, and a second L-shaped ventilation pipe 5 is fixedly connected to the outer wall of one side of the electronic reversing valve 4, a connecting hose 6 is fixedly connected to the bottom end of one of the first L-shaped ventilation pipes 3 close to the electronic reversing valve 4, and the outer wall of the other end of the connecting hose 6 is fixedly connected to the second L-shaped ventilation pipe 5, the air source pressure regulating filter 2, the first L-shaped ventilation pipe 3 and the electronic reversing valve 4 are respectively fixedly connected to connecting air pipes 7, and the bottom end of the outer wall of the connecting air pipe 7 passes through the inner wall of the box body 1 and is fixedly connected to a quick connector 8, a trapezoidal explosion-proof door 9 is rotatably connected to one side of the outer wall of the box body 1, and a one-way air valve 10 is fixedly connected inside the trapezoidal explosion-proof door 9.

[0029] like Figure 1-5 As shown, a connection groove 801 is provided at the top of the quick connector 8, and a plurality of fixing blocks 802 are fixedly connected at the edge of the bottom surface of the quick connector 8, the outer wall of the fixing block 802 is provided with an inclined surface, the outer wall of the quick connector 8 is provided with a thread, and the quick connector 8 is fixedly connected with a hexagonal fixing bolt 803 through the outer wall thread, the inner wall of the hexagonal fixing bolt 803 is slidably connected to the outer wall of the fixing block 802, a spring stabilizing groove 804 is fixedly connected to the bottom of the outer wall of the fixing block 802, and a coil spring 805 is movably connected inside the spring stabilizing groove 804, and the coil spring 805 is located at the bottom of the quick connector 8.

[0030] Before installing and connecting the device to the outer wall, the hexagonal fixing bolt 803 is placed flush with the quick connector 8 through thread rotation, so that the fixing block 802 and the coil spring 805 remain relaxed, and the outer wall connecting pipe is inserted into the inner part of the quick connector 8, and the external connecting pipe is aligned with the connecting groove 801 and abutted to the top of the inner part of the connecting groove 801. Then, the hexagonal fixing bolt 803 is rotated downward through the outer wall thread of the quick connector 8, and through the outer wall inclined surface of the fixing block 802. When the hexagonal fixing bolt 803 continues to rotate downward, the fixing block 802 abuts against the outer wall of the external connecting head and fixes the outer wall connecting head. When the external connecting pipe needs to be removed, only the hexagonal fixing bolt 803 needs to be rotated upward, and the coil spring 805 will open the fixing block 802 outward through its own elastic force, thereby making the device more convenient to install and disassemble with the external connecting pipe.

[0031] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a group of corresponding air relief grooves 901 are opened on one side of the outer wall of the movable explosion-proof door 9, an active cavity 1001 is opened at the center inside the one-way air valve 10, and a group of air outlet grooves 1002 are opened at the upper and lower ends of the inner wall of the active cavity 1001, one end of the air outlet groove 1002 is interconnected with the air relief groove 901, an air inlet 1003 is opened at the center of the outer wall of the one-way air valve 10, and the air inlet 1003 is interconnected with the active cavity 1001, a resistance spring 1004 is fixedly connected to one end of the active cavity 1001, a one-way valve core 1005 is fixedly connected to one end of the resistance spring 1004 close to the air inlet 1003, and an outer wall of the one-way valve core 1005 close to the air outlet is provided with an inclined surface, and the outer wall of the one-way valve core 1005 is slidably connected to the inner wall of the active cavity 1001.

[0032] When the gas source pressure regulating filter 2 leaks, the internal air pressure increases, and the air enters the one-way air valve 10 through the air inlet 1003, and pushes the one-way valve core 1005 toward the outside of the device. By compressing the resistance spring 1004, the air can enter the one-way air valve 10 along the inclined surface of one end of the one-way valve core 1005 and reach the outer wall of the device through the air outlet groove 1002 and the air discharge groove 901. When the device encounters a gas leak, the internal gas of the device can be discharged through the one-way air valve 10 to avoid excessive internal air pressure, which may cause a gas explosion in the device and create a safety hazard.

[0033] Working principle: Before installing and connecting the device to the outer wall, rotate the hexagonal fixing bolt 803 through the thread to be flush with the quick connector 8, keep the fixing block 802 and the coil spring 805 loose, insert the outer wall connecting pipe slot into the inner part of the quick connector 8, align the external connecting pipe with the connecting groove 801, and after it contacts the top of the inner part of the connecting groove 801, rotate the hexagonal fixing bolt 803 downward through the outer wall thread of the quick connector 8, through the outer wall inclined surface of the fixing block 802, when the hexagonal fixing bolt 803 continues to rotate downward, the fixing block 802 contacts the outer wall of the external connector, and the outer wall connector is fixed. When the external connecting pipe needs to be removed, just rotate the hexagonal fixing bolt 8 03 rotates upward, and the coil spring 805 opens the fixed block 802 outward through its own elastic force. When the air source pressure regulating filter 2 leaks, the internal air pressure increases, and the air enters the one-way air valve 10 through the air inlet 1003, and pushes the one-way valve core 1005 toward one end outside the device. By compressing the spring 1004, the air can enter the one-way air valve 10 along the inclined surface of one end of the one-way valve core 1005 and reach the outer wall of the device through the air outlet groove 1002 and the air discharge groove 901. When the device encounters a gas leak, the internal gas of the device can be discharged through the one-way air valve 10 to avoid excessive internal air pressure, which may cause a gas explosion in the device and cause a safety hazard.
