Description

Technical Field

[0001] The utility model belongs to the field of measuring instruments, and particularly relates to a corrosion-resistant stainless steel water meter housing device. Background Art

[0002] A water meter is a measuring instrument used to measure and record the water consumption, and is widely used in households, commercial and industrial fields. Traditional water meters are usually mechanical, relying on the water flow to drive the internal gear system, and then driving the pointer or roller to display the accumulated water consumption. Such water meters have simple structures and are durable, but the accuracy may decrease due to wear after long-term use.

[0003] The existing water meter housings are mostly made of cast iron or plastic. Although these materials meet the basic usage requirements to a certain extent, they have deficiencies in terms of corrosion resistance, wear resistance, high temperature resistance, etc. Especially in harsh environments, the water meter housings made of traditional materials are prone to problems such as corrosion and aging, thus affecting the service life and measurement accuracy of the water meter. Therefore, it is particularly necessary to develop a water meter housing device with higher corrosion resistance, wear resistance and high temperature resistance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a corrosion-resistant stainless steel water meter housing device, which adopts 304 precision steel food-grade stainless steel material, combines welding and casting processes to achieve excellent corrosion resistance, wear resistance and high temperature resistance.

[0006] Preferably, a water inlet through hole and a water outlet through hole are respectively arranged on both sides of the main core cavity.

[0007] Preferably, a joint is arranged inside the water inlet through hole, and the joint is shaped like a spiral.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0019] Embodiment 1, as Figure 1As shown in the figure, a corrosion-resistant stainless steel water meter housing device includes a main core cavity 1. A stainless steel meter cover 2 is provided above the main core cavity 1. A circular plastic sheet 3 is provided inside the stainless steel meter cover 2. An inlet through hole 4 and an outlet through hole 5 are respectively provided on both sides of the main core cavity 1. A connector 6 is provided inside the inlet through hole 4. A movement 7 is provided on one side of the inlet through hole 4. A valve body 8 is connected to one side of the outlet through hole 5. A connector 9 is provided on one side of the valve body 8. A polytetrafluoroethylene gasket 10 is provided on one side of the connector 9. A ball valve 11 is provided on one side of the polytetrafluoroethylene gasket 10. A valve stem 12 is provided above the ball valve 11.

[0020] A stainless steel meter cover 2 is provided above the main core cavity 1. The stainless steel meter cover 2 provides a layer of solid protection for the circular plastic sheet 3, preventing physical damage, corrosion, dust, and other pollutants in the external environment from affecting the circular plastic sheet 3. Through the circular plastic sheet 3, the working condition of the water meter and the usage condition of the water flow can be observed in real time. An inlet through hole 4 and an outlet through hole 5 are respectively provided on both sides of the main core cavity 1. A connector 6 is provided inside the inlet through hole 4. The shape of the connector 6 is set as a spiral shape. The spiral shape provides a firm connection. Through the way of rotational fastening, the connection part can bear greater pressure and torsion, and is not easy to loosen or fall off. The spiral interface also has good sealing performance, which can effectively prevent the leakage of liquid water. A movement 7 is provided on one side of the inlet through hole 4. The movement 7 is the core component of the water meter, responsible for measuring and recording the water flow. It converts the kinetic energy of the water flow into readable data through internal mechanical or electronic devices, and then transmits the flow information to the dial or digital display through a gear set or electronic sensor. A valve body 8 is connected to one side of the outlet through hole 5. A connector 9 is provided on one side of the valve body 8. A polytetrafluoroethylene gasket 10 is provided on one side of the connector 9. The polytetrafluoroethylene gasket 10 is mainly used for sealing. It can form a reliable seal between the connector 9 and the ball valve 11 to prevent water leakage. Since polytetrafluoroethylene has excellent chemical corrosion resistance and extremely low friction coefficient, it can remain stable when in contact with water and other chemical substances for a long time, is not easy to age or deform, thus extending the service life of the water meter. A ball valve 11 is provided on one side of the polytetrafluoroethylene gasket 10. The ball valve 11 in the water meter mainly plays the role of controlling the water flow. The ball valve 11 adjusts the on-off of the water through a rotating sphere with a through hole. When the ball valve 11 is in the open state, the water can pass through smoothly; when the ball valve 11 is closed, the water flow is completely blocked. A valve stem 12 is provided above the ball valve 11. Six O-rings 13 are installed at the bottom of the valve stem 12 to ensure the complete seal between the stainless steel housing and the valve stem 12, and at the same time play a protective role in the seal of the valve stem 12.

[0021] Next, specifically describe the specific design of the above key components:

[0022] As Figure 2As shown, the water meter housing adopts a die-stretched structure to form a straight-barrel housing. Compared with the housing with an arc design, the straight-barrel structure is simple and easy to manufacture. Moreover, during the welding process, there is no need to consider the error of the arc surface, which improves the welding precision and appearance. The welding process of 304 precision steel ensures the structural stability of the water meter housing, while the casting process makes the valve body 8 and the water outlet through-hole 5 integrally formed, avoiding the weld seams and water leakage problems that may occur in the traditional welding process. The water outlet through-hole 5 and the water meter housing are welded by arc surface positioning, and the water outlet through-hole 4 and the water meter housing also adopt the arc surface positioning welding process, ensuring the absolute fit between the water meter housing and the water inlet and outlet.

[0024] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
