Description

Technical Field

[0001] This utility model relates to the field of water meter casting technology, and in particular to a horizontal mid-section water inlet casting structure for stainless steel water meter housings. Background Technology

[0002] The water meter casing is an important component of the water meter. Its main function is to protect the internal components of the water meter, providing a safe housing space to protect it from external physical damage, dust, and moisture, thereby ensuring that the water meter can accurately measure the water flow.

[0003] The water meter casing uses a horizontal mid-section water inlet casting structure. It is made with a precise mold according to the design requirements of the horizontal mid-section water inlet of the stainless steel water meter casing. The precision and quality of the mold directly affect the dimensional accuracy and surface quality of the water meter casing. High-precision processing equipment and processes are usually used to manufacture the mold to ensure that its inner cavity surface is smooth, the dimensions are accurate, and it has good demolding performance.

[0004] In existing technologies, the use of a horizontal mid-section water inlet casting structure for stainless steel water meter housings allows water to flow smoothly into the metering chamber, reducing water flow disturbance and eddies, and providing a stable working environment for the impeller's metering components, thereby improving the metering accuracy of the water meter and ensuring accurate measurement of water consumption. However, during casting, excessively rapid cooling can cause the molten steel to become too cold, blocking the filling of the molten steel and resulting in casting gaps and shrinkage cavities. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a horizontal mid-section water inlet casting structure for stainless steel water meter housing, which aims to improve the problem in the prior art where excessively rapid cooling can lead to overcooling of molten steel, blocking the filling of the molten steel and causing casting gaps and shrinkage cavities.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a horizontal mid-section water inlet casting structure for a stainless steel water meter casing, comprising a water meter casing, a core main casting channel at the rear end of the water meter casing, a top riser fixedly connected to the top of the core main casting channel, multiple branch casting channels fixedly connected to the left and right ends of the core main casting channel, a support casting column fixedly connected to the other end of the branch casting channel, an exhaust riser fixedly connected to the top of the support casting column, and multiple planar rectangular water inlets fixedly connected to the front and rear ends of the support casting column.

[0007] As a further description of the above technical solution:

[0008] A meter bar is fixedly connected to the outer wall of the water meter casing, and a fixing block is fixedly connected to the left end of the meter bar.

[0009] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] A water inlet block is fixedly connected to the right end of the water meter casing, and a water inlet ring is fixedly connected to the right side of the water inlet block.

[0013] As a further description of the above technical solution:

[0014] A water outlet block is fixedly connected to the left end of the water meter casing, and a water outlet ring is fixedly connected to the left side of the water outlet block.

[0015] As a further description of the above technical solution:

[0016] A connecting ring is fixedly connected to the front end of the water outlet ring, and a locking block is fixedly connected to both the upper and lower ends of the connecting ring.

[0017] As a further description of the above technical solution:

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the molten steel enters the core main gating through the top riser, and then flows from the core main gating through the branch gating to the support gating column. The vent riser fixed on the support gating column provides uniform venting, thereby improving the average pouring of the casting equipment, reducing the pouring time, and solving the problem that if the cooling is too fast, the molten steel will become too cold and block the filling of the molten steel, resulting in casting gaps and shrinkage cavities.

[0021] 2. In this utility model, the horizontal stacking pouring method using a combination of planar rectangular water inlets allows for multi-layer pouring. The number of layers can be increased according to the required quantity, and the finished product yield is high, thereby improving overall production efficiency and solving the problem of low production efficiency.
