Description

Technical Field

[0001] This utility model relates to the field of water meter housing technology, specifically to a check valve water meter housing. Background Technology

[0002] A water meter is an instrument used to measure water flow. The water meter casing is a housing device used to install the water meter. Once the flow-measuring mechanism is installed inside, it becomes a usable water meter. The two ends of the water meter casing are the inlet and outlet, used to connect to the water pipes. Water flows into the inlet channel from the inlet, then through the flow-measuring mechanism into the outlet channel, and finally out of the outlet channel. The flow-measuring mechanism measures the water flow. A water meter casing with a check valve is a type of water meter casing with a check valve on the outlet channel side. This effectively prevents reverse water flow and avoids the meter from spinning dry, ensuring accurate measurement.

[0003] Currently, check valve water meter housings are mainly manufactured through integral casting. However, due to the complexity of the internal structure, quality defects such as sand holes and air pores are prone to occur during the casting process. Furthermore, the height of the main body of the check valve water meter housing needs to be adjusted according to the size of the water meter movement, and since movement sizes vary on the market, the height of the main body of the check valve water meter housing also needs to be flexibly adjusted according to requirements. If check valve water meter housings produced using traditional integral casting processes are to be configured with different heights according to different requirements, it is necessary to uniformly modify the entire structure, including the main body, inlet, and outlet, resulting in a complex process and higher costs.

[0004] Therefore, the existing check valve water meter housing needs to be improved to solve the above problems. Utility Model Content

[0005] This utility model proposes a check valve water meter housing, which solves the problem of the relatively complex production and processing of water meter housings in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] A check valve water meter housing includes an integrally formed main body, an inlet pipe, and an outlet pipe. The main body is used to install a mechanism for measuring water flow. The main body has an opening on its upper side and inlets and outlets on both sides. The inlet pipe is located at the inlet, and the outlet pipe is located at the outlet. The main body is formed by hydraulic stretching.

[0008] As a further technical solution, it also includes,

[0009] A baffle ring is disposed within the main body, with the water inlet located below the baffle ring and the water outlet located above the baffle ring.

[0010] As a further technical solution, the main body also has a constriction, and the retaining ring is inserted into the main body before the constriction is formed.

[0011] As a further technical solution, it also includes,

[0012] An outer connecting ring is disposed on the main body and located at the opening.

[0013] As a further technical solution, both the inlet pipe and the outlet pipe are cast.

[0014] As a further technical solution, the water outlet pipe has a mounting hole for installing a check valve body.

[0015] As a further technical solution, the water inlet pipe, the water outlet pipe, and the outer connecting ring all have external threads, which are uniformly processed after the water inlet pipe, the water outlet pipe, and the retaining ring are welded to the main body.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] In this utility model, in order to solve the problem that the production and processing of check valve water meter housing is relatively complicated in related technologies, the check valve water meter housing is divided into three parts: water inlet, water outlet and main body. These parts are produced independently and then welded together. The main body is formed by hydraulic stretching. Compared with casting, it is easier to adjust the height of the main body according to the size of the mechanism, making the processing procedure simpler. Attached Figure Description

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] A check valve water meter housing includes a main body 1, an inlet pipe 2, and an outlet pipe 3, which are integrally formed. The main body 1 is used to install the mechanism for measuring water flow. The main body 1 has an opening 4 on the upper side and an inlet 5 and an outlet 6 on both sides. The inlet pipe 2 is located at the inlet 5, and the outlet pipe 3 is located at the outlet 6. The main body 1 is formed by hydraulic stretching.

[0031] like Figures 1-3 As shown in this embodiment, in order to solve the problem that the production and processing of water meter casings is relatively complicated in related technologies, the main body 1 of the water meter casing is integrally formed by hydraulic stretching. Compared with casting, it is more convenient to adjust the size of the main body 1 according to the size of the movement, making the processing procedure simpler.

[0032] Furthermore, it also includes a baffle ring 7, which is disposed inside the main body 1, with the water inlet 5 located below the baffle ring 7 and the water outlet 6 located above the baffle ring 7. Furthermore, the main body 1 also has a constriction 8, and the baffle ring 7 is inserted into the main body 1 before the constriction 8 is formed.

[0033] like Figure 2 As shown, in this embodiment, the main body 1 is integrally hydraulically stretched and formed. After hydraulic stretching, the inner diameter of the main body 1 is the same as the outer diameter of the retaining ring 7, so that the retaining ring 7 can be inserted into the main body 1 and tightly connected. After the retaining ring 7 is inserted, the main body 1 is narrowed 8. The narrowing of the opening on the upper side of the main body 1 also facilitates the connection of other parts.

[0034] Furthermore, it also includes an outer connecting ring 9, which is disposed on the main body 1 and located at the constriction 8.

[0035] like Figure 1 , Figure 2 As shown, in this embodiment, the outer connecting ring 9 needs to be welded to the main body 1 for connecting other accessories.

[0036] Furthermore, both the inlet pipe 2 and the outlet pipe 3 are cast in shape.

[0037] like Figure 4 , Figure 5 As shown, in this embodiment, the forming process of the water inlet pipe 2 and the water outlet pipe 3 remains unchanged, and casting forming is adopted in the prior art.

[0038] Furthermore, the outlet pipe 3 has a mounting hole 10 for mounting a check valve body.

[0039] like Figure 5 As shown in this embodiment, the water outlet pipe 3 also has an installation hole 10, which can be used to install a check valve, and can be used to block the backflow of the medium in the water channel in a timely manner.

[0040] Furthermore, the inlet pipe 2, the outlet pipe 3, and the outer connecting ring 9 all have external threads 11. The external threads 11 are uniformly processed after the inlet pipe 2, the outlet pipe 3, and the retaining ring 7 are welded to the main body 1.

[0041] like Figures 4-6 As shown, in this embodiment, the external thread 11 is processed as the final step, and is uniformly processed to ensure the accuracy of the finished product dimensions.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
