Description

Technical Field

[0001] This utility model relates to a water meter housing, and more particularly to a vertical stainless steel valve-controlled housing. Background Technology

[0002] In vertical water meters, the inlet and outlet are typically located on the same side, with the inlet pipe below the outlet pipe. Both the inlet and outlet pipes include horizontal and vertical sections, with the vertical sections coaxial in the vertical direction. In vertical valve-controlled water meters, the ball valve is usually located in the vertical or horizontal section of the outlet pipe, such as CN211527490U and CN209280064U. However, regardless of whether it's located in the vertical or horizontal section, the length of the corresponding part needs to be increased, increasing the size of the water meter and making later installation inconvenient.

[0003] In this regard, the applicant has applied for a vertical valve-controlled water meter housing with publication number CN220251106U. This patent sets the ball valve at the intersection of the horizontal pipe and the vertical pipe and adopts the structure of a three-way ball valve to realize the setting of the water meter outlet switch. Compared with simply setting the ball valve in the horizontal pipe or the vertical pipe, this utility model has the advantages of small size and convenient installation.

[0004] However, in the above structure, the pressure loss of water flow at the ball valve position is relatively large, and optimization is needed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a vertical stainless steel valve control housing, which has the advantages of small size and low pressure loss. To achieve the above objective, this utility model adopts the following technical solution:

[0007] (II) Technical Solution

[0008] A vertical stainless steel valve control housing includes a housing body and a vertical tube connected by a horizontal tube. A water divider is horizontally positioned in the middle of the horizontal tube, dividing it into a lower inlet channel and an upper outlet channel. A water passage hole is opened on one side of the vertical tube, communicating with both the inlet and outlet channels. A valve body is located at the intersection of the vertical tube and the outlet channel. A flow guide is located at the end of the outlet channel near the valve body, and this flow guide is shaped like a flared mouth, smaller on the left and larger on the right. A baffle is located inside the vertical tube below the valve body, separating the spaces of the vertical tube on its upper and lower sides.

[0009] Furthermore, the barrier is a lower support frame, and the bottom of the lower support frame is provided with a retaining ring, which is threadedly connected to the bottom of the vertical pipe.

[0010] Furthermore, the lower support frame has a hollow structure in the middle, and its top and bottom are connected by several support columns.

[0011] Furthermore, the valve body is provided with an upper support frame at the top, and the upper support frame is provided with a retaining ring at the top, which is threadedly connected to the top of the vertical pipe.

[0012] Furthermore, the upper support frame has a flared shape that is wider at the top and narrower at the bottom.

[0013] Furthermore, the barrier is a support ring, which is located at the bottom of the valve body and higher than the water passage below, and the support ring is fixed to the inner wall of the vertical pipe by welding.

[0014] Furthermore, the water distribution plate is provided with a number of positioning protrusions for positioning the flow guide frame.

[0015] Furthermore, the number of positioning protrusions is two, and they are centrally symmetrically arranged on the upper and lower sides of the water distribution plate.

[0016] (III) Beneficial Effects

[0017] This utility model has significant advantages and beneficial effects compared with the prior art, specifically:

[0018] 1. By setting the ball valve at the intersection of the horizontal and vertical pipes, the water meter's outlet switch can be set. Compared with simply setting the ball valve inside the horizontal or vertical pipe, this utility model has the advantages of small size and convenient installation.

[0019] 2. The valve body is equipped with a flow guide and an upper support frame at the upstream and downstream ends, respectively, which effectively reduces the pressure loss at the valve body;

[0020] 3. The water distribution plate is equipped with centrally symmetrical positioning protrusions. These protrusions are formed on the water distribution plate by embossing, which is more efficient than welding positioning blocks. The centrally symmetrical design facilitates the positioning of the flow guide frame without affecting the assembly efficiency of the water distribution plate. Attached Figure Description

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Example 1

[0041] Please see Figures 1 to 6 As shown, a vertical stainless steel valve control housing includes a housing body 1 and a vertical pipe 2, which are connected by a horizontal pipe 3, wherein:

[0042] A water divider plate 31 is horizontally provided in the middle of the horizontal pipe 3, which divides the horizontal pipe 3 into a lower water inlet channel 32 and an upper water outlet channel 33; a water passage hole 21 is opened on one side of the vertical pipe 2, which is connected to the water inlet channel 32 and the water outlet channel 33 respectively.

[0043] A valve body 6 is provided at the intersection of the vertical pipe 2 and the water outlet channel 33, and a valve hole 4 is provided at the valve body 6 in the vertical pipe 2 for installing the valve stem; a flow guide 8 is provided at one end of the water outlet channel 33 near the valve body 6. The flow guide 8 is in the shape of a flared mouth with a smaller left side and a larger right side, which can effectively reduce the pressure loss generated by the water flow at the valve body 6.

[0044] The vertical pipe 2 below the valve body 6 is provided with a lower support frame 5. The top of the lower support frame 5 separates the bottom of the valve body 6 from the water passage hole 21 below. The middle part of the lower support frame 5 is a hollow structure. Its top and bottom are connected by several support columns 51 to achieve a larger water passage area, thereby reducing pressure loss.

[0045] The valve body 6 is provided with an upper support frame 7, which is in the shape of a flared mouth that is larger at the top and smaller at the bottom, and also serves to guide the flow.

[0046] It is understood that the bottom of the lower support frame 5 and the top of the upper support frame 7 are both provided with retaining rings 9. The retaining rings 9 are fixedly connected to the inner wall of the port of the vertical pipe 2 by means of threaded connection or welding. In this solution, the retaining rings 9 are used to limit the bottom of the lower support frame 5 and the upper support 7, thereby fixing the valve body 6. During assembly, only the retaining rings 9 at both ends need to be fixed, which greatly reduces the assembly difficulty and improves the assembly efficiency.

[0047] It is worth mentioning that, because the guide frame 8 needs to be positioned during welding and fixing, therefore, as Figure 5 and 6 As shown, the water distribution plate 31 is provided with a plurality of positioning protrusions 311 for positioning the flow guide frame 8.

[0048] Preferably, the positioning protrusions 311 are formed on the water distribution plate 31 by embossing, which has higher production efficiency than welding positioning blocks; and the number of positioning protrusions 311 is two and they are centrally symmetrically arranged on the upper and lower sides of the water distribution plate 31, so that the water distribution plate 31 does not need to distinguish between the front and back when it is installed, further improving the assembly efficiency.

[0049] Example 2

[0050] The difference between this embodiment and Implementation 1 is that: Figure 7 The lower support frame 5 is no longer provided below the valve body 6, but is replaced by a support ring 10. The support ring 10 is located at the bottom of the valve body 6 and is higher than the water passage hole 21 below. The support ring 10 is fixedly connected to the inner wall of the vertical pipe 2 by welding.

[0051] Compared to Embodiment 1, which only requires welding the retaining ring 9 at the end of the vertical pipe 2, this embodiment slightly increases the welding difficulty of the support ring 10, but eliminates the need to manufacture the complex lower support frame 5, reducing material usage and production costs.

[0052] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
