DETAILED DESCRIPTION

[0019] 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.

[0020] During assembly of the existing housing, the cover material is resistant to high pressure, which results in a large counterweight, making it difficult to find the installation position when tightening the bolts, thus prolonging the operation time.

[0021] In view of this, a shell of a boiler pump body is provided, in which the positioning of the cover body is achieved through the cooperation between the shell, the block and the tension spring. When connecting the bolts, there is no need to hold the cover body by hand, which solves the problem that during assembly of the existing shell, the cover body material is resistant to high pressure, resulting in a large counterweight, which makes it difficult to find the installation position when tightening the bolts, thereby prolonging the operation time.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: Figure 1-4 It can be seen that a shell of a boiler pump body includes a shell 1, a cover body 5 is attached to the front of the shell 1, a limit block 17 movably connected to the front opening of the shell 1 is fixedly connected to the inner side of the cover body 5, a main shaft 9 is fixedly connected to the inner side of the limit block 17, and a positioning mechanism is arranged on the front of the shell 1. The positioning mechanism includes a slot 8, a plug rod 10, a slot body 6, a block 14 and a plug plate 15. The slot 8 is opened on the inner side of the cover body 5, and the inner side of the slot 8 is movably connected to the plug rod 10, and the plug rod 10 can move inside the slot 8. The back of the plug rod 10 is fixedly connected to the front of the shell 1. The plug rod 10 plays a positioning role. There are at least two of them. A block 14 fixed to the front of the shell 1 is arranged above the plug rod 10. The through hole of the block 14 is movably connected with a plug plate 15. The plug plate 15 can move in the through hole of the block 14. The lower part of the outer wall of the plug plate 15 is movably connected with a groove body 6 opened on the top of the cover body 5. The plug plate 15 can be inserted in the groove body 6 for positioning. The limit block 17 can be snapped into the opening on the front of the shell 1 for positioning;

[0024] In the specific implementation process, it is worth pointing out that the positioning of the cover body 5 is achieved through the cooperation between the slot body 6, the block 14 and the plug plate 15. When connecting the bolts, there is no need to hold the cover body 5 by hand, which solves the problem that when assembling the existing shell, the cover body 5 material is resistant to high pressure, resulting in a large counterweight, which makes it difficult to find the installation position when tightening the bolts, thereby prolonging the operation time.

[0025] Furthermore, a stopper 18 is fixedly connected to the upper front of the plug plate 15, and the bottom of the stopper 18 is fixedly connected to the top of the block 14 via a tension spring 16;

[0026] In the specific implementation process, it is worth pointing out that the device can drive the plug board 15 to be inserted into the slot body 6 for positioning by relying on the elastic deformation of the tension spring 16;

[0027] Furthermore, two input terminals 20 are installed on the top of the housing 1, and a bracket 19 is installed on the bottom of the housing 1;

[0028] In the specific implementation process, it is worth pointing out that the two input ends 20 are respectively a water inlet and a water outlet;

[0029] Specifically, when using the shell of the boiler pump body, the user can align the two slots 8 on the cover body 5 with the insertion rod 10 and insert it. Before it is fully inserted, the insertion plate 15 needs to be pulled upward. After the cover body 5 is fitted with the shell 1, the insertion plate 15 is released. At this time, the elastic deformation of the tension spring 16 can drive the insertion plate 15 to be inserted into the groove body 6 for positioning without affecting the fixing of the cover body 5 and the shell 1.

[0030] Embodiment 2: By Figure 1-2 It can be seen that a plurality of threaded holes 13 are processed on the front of the housing 1, and the inner side of the threaded holes 13 is threadedly connected with bolts 7, and the bolts 7 can be fixed on the threaded holes 13 for fixing, and the outer side of the bolts 7 is threadedly connected with the inner side of the cover body 5, and the first sealing ring 11 and the second sealing ring 12 are installed on the surface of the housing 1;

[0031] In the specific implementation process, it is worth pointing out that the first sealing ring 11 and the second sealing ring 12 improve the sealing performance of the contact position between the cover body 5 and the housing 1;

[0032] Furthermore, a base layer 3 is provided inside the shell 1, a corrosion-resistant layer 4 is provided inside the base layer 3, and a protective layer 2 is provided outside the base layer 3;

[0033] In the specific implementation process, it is worth pointing out that the material of the base layer 3 is cast steel, which is a high-strength metal material and is widely used in high-pressure and high-speed pumps;

[0034] Specifically, on the basis of the above-mentioned first embodiment, through the cooperation among the housing 1, the first sealing ring 11 and the corrosion-resistant layer 4, the pressure resistance and corrosion resistance of the housing 1 are improved, and the service life is extended.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0036] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
