Technical Field
[0001] The utility model relates to the field of boilers, in particular to a one-piece boiler component. Background Art
[0002] A one-piece boiler assembly is actually a valve device similar to a one-piece ball valve. The boiler assembly is more like an integration of multiple valves, with a safety valve and an automatic exhaust valve. The safety valve can prevent excessive pressure in equipment and containers, and its opening pressure is higher, while the automatic exhaust valve can remove gas from the system to achieve better working results or pressure relief purposes, and its opening pressure is lower. At the same time, the one-piece filter assembly has a pressure gauge for real-time monitoring of steam pressure and timely pressure adjustment.
[0003] When using a boiler, steam transportation is involved, and the one-piece boiler assembly is the weak link in the insulation of steam transportation. The traditional one-piece boiler assembly does not have any insulation structure. At this time, due to the temperature difference between the external environment and the steam, heat will be dissipated to the outside, resulting in the loss of steam thermal energy, and at the same time affecting the steam pressure. If an insulation structure is set outside the main body of the one-piece boiler assembly, the installation layout of the safety valve, automatic exhaust valve and pressure gauge will be affected, and ultimately the exhaust direction of the automatic exhaust valve and safety valve will be not much different from or the same as the observation direction of the pressure gauge. In this case, the staff can easily be scalded by the discharged steam, posing a serious safety hazard. Summary of the Invention

[0023] The front cover 901 and the rear cover 902 are both made of foam material.
[0024] A matching bushing 18 is screwed into the screw hole 7 ; the mounting head 801 is screwed into the inner screw hole 1801 of the bushing 18 .
[0025] The exhaust ends 19 of the automatic exhaust valve 4 and the safety valve 5 are located at their upper ends or at their front and rear sides.
[0026] The method of using the utility model is as follows:
[0027] The insulation shell 9 that completely wraps the boiler valve body 1 is divided into a front cover shell 901 and a rear cover shell 902, so that the installation of the insulation shell 9 will not be restricted by the automatic exhaust valve 4, the safety valve 5 and the pressure gauge 8. While achieving insulation, it ensures that the automatic exhaust valve 4, the safety valve 5 and the pressure gauge 8 can be installed according to actual needs. At this time, the pressure display of the pressure gauge faces right, so the staff only needs to stand on the right side of the boiler valve body 1 to easily observe the real-time pressure, and the automatic exhaust valve 4 and the safety valve 5 are both arranged above the boiler valve body 1, away from the observation position of the pressure gauge 8, so as to effectively avoid the situation where the exhaust direction of the automatic exhaust valve 4 and the safety valve 5 is not much different from or the same as the observation direction of the pressure gauge 8, thereby effectively eliminating safety hazards.
[0028] The exhaust valve connector 2 can determine the installation position of the automatic exhaust valve 4, the safety valve connector 3 can determine the installation position of the safety valve 5, the screw hole 7 can determine the installation position of the pressure gauge 8, and the hole formed by the left front notch 12 of the front cover 901 and the left rear notch 13 of the rear cover 902 can effectively accommodate the existence of the exhaust valve connector 2, so the installation position of the automatic exhaust valve 4 will not interfere with the installation of the insulation shell 9, and the hole formed by the right front notch 14 of the front cover 901 and the right rear notch 15 of the rear cover 902 can effectively accommodate the existence of the safety valve connector 3 Therefore, the installation position of the safety valve 5 will not interfere with the installation of the insulation shell, and the hole formed by the front auxiliary recess 16 of the front cover shell 901 and the rear auxiliary recess 17 of the rear cover shell 902 can effectively accommodate the existence of the installation head 801, so the installation position of the pressure gauge 8 will not interfere with the installation of the insulation shell 9, and the hole formed by the lower front recess of the front cover shell 901 and the lower rear recess 11 of the rear cover shell 902 can effectively accommodate the existence of the connecting joint 6, so after the connecting joint 6 can be connected to the steam delivery system, it will also not interfere with the installation of the insulation shell 9.
[0029] The front cover shell 901 and the rear cover shell 902 are both made of foam material, which can effectively ensure the thermal insulation effect of the thermal insulation shell 9, and the front cover shell 901 and the rear cover shell 902 are connected and fixed by a number of evenly distributed Ma Wang nails 10. The Ma Wang nails 10 can be easily nailed into the foam material and are easy to remove from the foam material. Therefore, this fixing method can not only ensure the stability of the front cover shell 901 and the rear cover shell 902 when they are fixed, but also facilitate the disassembly and assembly of the front cover shell 901 and the rear cover shell 902, and facilitate the replacement of the thermal insulation shell 9.
[0030] A matching bushing 18 is threadedly connected to the threaded hole 7. The mounting head 801 is threadedly connected to the inner threaded hole 1801 of the bushing 18. The presence of the bushing 18 acts as an adapter, avoiding the difficulty in installing the pressure gauge 8 when the mounting head 801 and the threaded hole 7 are not the same size, thereby facilitating the installation of pressure gauges of different models.
[0031] The exhaust ends 19 of the automatic exhaust valve 4 and the safety valve 5 are located at their upper ends or at the front and rear sides thereof. At this time, the exhaust directions of the automatic exhaust valve 4 and the safety valve 5 and the observation direction of the pressure gauge will not intersect at all, thereby avoiding to the greatest extent the situation where the staff is scalded by the gas discharged by the automatic exhaust valve 4 and the safety valve 5 when observing the pressure gauge, thereby ensuring safety to the greatest extent.
[0032] A non-return structure may be provided in the automatic exhaust valve 4. By adopting the existing non-return structure, the non-return core 20 and the spring 21 are utilized to achieve the non-return effect, thereby effectively improving the safety performance of the automatic exhaust valve.
[0033] When the lower end of the automatic exhaust valve 4 is screwed into the exhaust valve joint 2, the lower end of the safety valve 5 is screwed into the safety valve joint 3, and the bushing 18 is screwed into the screw hole 7, glue can be used for sealing to effectively avoid leakage.
