Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gas and fluid valve technology, specifically relating to a novel valve body with an integrated pressure sensing module. Background Technology
[0002] The valve body is a major component of a valve, and its mechanical manufacturing methods vary depending on the pressure rating. It is a device that allows the medium within piping and equipment to flow or stop, and controls its flow rate. Gas and water valves used by urban residents are typically standalone valves with relatively simple functions; there are currently no valves on the market that integrate pressure sensing modules. If a valve body's linkage control requires collecting the pressure of the medium before and after the valve, a separate pressure sensor is needed. This increases the risk of pipeline leaks and raises construction and maintenance costs, especially in gas safety applications, where gas leaks pose a significant safety hazard. Utility Model Content
[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a novel valve body integrating a pressure sensing module to solve the problems mentioned in the background art.
[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0005] A novel valve body integrating a pressure sensing module includes a valve body with an inlet and an outlet at its two ends, a valve core in the middle of the valve body, and connecting portions on both sides of the valve core. Each connecting portion has a mounting hole for the pressure sensing module, which communicates with passages on both sides of the valve body. The upper side of the mounting hole is threaded, and the mounting hole is used to install the pressure sensing module. The diameter of the sampling hole at the lower part of the mounting hole, which communicates with the passage, is much smaller than that at the upper part of the mounting hole; the sampling hole has a diameter of 1.0 mm. The mounting hole as a whole is stepped, tapering inwards.
[0006] Further specifying, the pressure sensing module includes a sealing part to prevent gas or water from passing through and a sensing part for sensing the pressure exerted on the gas or water, the mounting hole being threadedly connected to a housing, and the sealing part and the sensing part being located inside the housing.
[0007] Further specifying, the sensing unit includes a sintered metal sheet, and a circuit board and a pressure sensor are mounted and connected to the upper side of the sintered metal sheet, with lead wires connected to the upper side of the circuit board and the pressure sensor.
[0008] Further specified, the sintered metal sheet is located in a stepped groove above the mounting hole.
[0009] Further specifying, the sealing part includes a sealing gasket located above the metal sintered sheet and below the housing, a waterproof and breathable membrane is adhered directly below the pressure sensor, and an adhesive layer is provided on the upper side of the waterproof and breathable membrane.
[0010] Further specified, the lead wire is encapsulated within an adhesive layer, and the adhesive layer completely encapsulates the lower part of the adhesive layer.
[0011] Furthermore, the pressure sensing modules located on both sides of the valve core are connected to the valve body in an integral molding connection, adhesive bonding, or threaded connection.
[0012] Furthermore, the two connecting parts are either connected to each other or set separately.
[0013] Furthermore, the two connecting portions are located on the same side or on different sides.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] The valve body of this utility model has a pressure sensing module installed before and after the valve core to monitor the pressure changes of the medium before and after the valve. Through the pressure sensing module, the valve body can be opened and closed by monitoring the pressure changes before and after the valve core and then by controlling the module.
[0016] The valve body of this invention is small in size, compact in structure, easy to install, and highly adaptable. The addition of a pressure sensing module to the valve body will not affect the normal operation of the valve body.
[0017] The pressure sensing module of this utility model is threadedly connected to the valve body, which is convenient for disassembly. When it is necessary to replace or repair the pressure sensing module, the pressure sensing module can be easily removed. Attached Figure Description

Detailed Implementation
[0032] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains; the terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.
[0034] like Figure 1-11 As shown, a novel valve body integrating a pressure sensing module includes a valve body 1, with an inlet 11 and an outlet 12 at its two ends. A valve core 13 is disposed in the middle of the valve body 1. Connecting parts 2 are connected to both sides of the valve core 13. The connecting parts 2 have mounting holes 21 for the pressure sensing module. The mounting holes 21 are connected to the passages on both sides of the valve body 1. The upper side of the mounting holes 21 is threaded. The mounting holes 21 are used to install the pressure sensing module 3. The diameter of the sampling hole at the lower part of the mounting holes 21, which is connected to the passage, is much smaller than that at the upper part of the mounting holes 21. The diameter of the sampling hole is 0.5-1.0 mm. The mounting holes 21 are generally stepped inward.
[0035] The technical solution of this embodiment should be noted as follows: "Novel valve body" refers to a new type or style of valve body, specifically a valve body with pressure sensing function. Valve body 1 is not limited to water valves or gas valves. Furthermore, this structure does not limit the subcategories of valves. If the valve is a needle valve, butterfly valve, or gate valve, the corresponding valve cores are needle, butterfly, and gate types, respectively. When the pressure sensing module of this application is applied to a needle valve, butterfly valve, or gate valve, it is located on both sides of the valve core of the corresponding valve body. The connecting part 2 is used to connect the pressure sensing module 3. A threaded hole is provided on the inner side of the connecting part 2, allowing the pressure sensing module 3 to connect with the mounting hole 21. The thread has a self-locking characteristic, thus... Once the pressure sensing module 3 is rotated into the mounting hole 21, it can be connected to the valve body 1. The pipe at the bottom of the mounting hole 21 is connected to the gas or water passing through the valve body 1. The gas or water can reach the position of the pressure sensing module 3 through the pipe. The diameter of the mounting hole 21 gradually decreases downward in a stepped manner, so that only a small amount of gas or water can reach the position of the pressure sensing module 3. The pressure sensing module 3 is located on the front and rear sides of the valve core 13, so as to detect the pressure on both sides of the valve core 13. The mounting hole 21 gradually decreases from top to bottom, so that the diameter of the pipe connected to the two sides of the valve core 13 is small, and only a small amount of medium can pass through.
[0036] Reference Figure 2 , Figure 7 and Figure 8 The pressure sensing module 3 includes a sealing part to prevent gas or water from passing through and a sensing part for sensing the pressure on the gas or water. A housing 33 is threadedly connected to the mounting hole 21, and the sealing part and sensing part are located within the housing 33. In this embodiment, the pressure sensing module 3 is used to obtain the pressure of gas or water on both sides of the valve core 13 of the valve body 1. The sealing part is used to prevent water from entering the sensing part, and the housing 33 is used to install the sealing part and the sensing part.
[0037] Reference Figure 2The sensing element includes a sintered metal sheet 321. A circuit board 322 and a pressure sensor 323 are mounted and connected to the upper side of the sintered metal sheet 321. Lead wires 324 are connected to the upper sides of the circuit board 322 and the pressure sensor 323. In this embodiment, the sintered metal sheet 321 is used to filter gas or fluid to prevent impurities from entering the mounting hole. The pressure sensor 323 is an electronic device used to measure pressure; it can convert pressure into an electrical signal, thereby achieving accurate pressure monitoring. The circuit board 322 transmits the electrical signal obtained from the pressure sensor 323 through the lead wires 324.
[0038] Reference Figure 2 The sintered metal sheet 321 is located within the step above the channel of the mounting hole 21. In this embodiment, the sintered metal sheet 321 is located within the step above the channel, so that the sintered metal sheet 321 is in contact with only a small amount of gas or water.
[0039] Reference Figure 7 The sealing part includes a sealing gasket 311 located above the metal sintered sheet 321 and below the housing 33. A waterproof and breathable membrane 312 is adhered directly below the pressure sensor 323, and an adhesive layer 313 is provided on the upper side of the waterproof and breathable membrane. The lead wire 324 is sealed within the adhesive layer 313. In this embodiment, the sealing gasket 311 is used to prevent gas or water from entering the mounting hole, and the waterproof and breathable membrane 312 is used to allow gas to pass through. The waterproof and breathable membrane 312 is a flexible material with the ability to deform, so that the pressure sensor 323 can obtain pressure information within the mounting hole 21. The adhesive layer 313 is used to seal the lead wire 324. It is also easy to understand that the adhesive layer 313 is located within the cavity, and the lower part of the adhesive layer 313 is sealed, thus providing a sealing effect. It should be noted that the circuit board 322 is located between the adhesive layer 313 and the waterproof and breathable membrane 312. Module 3 consists of a housing 33. The housing 33 is preferably connected to the valve body by a threaded connection. Inside the housing 33, from top to bottom, there are lead wires 324 located in the sealing layer 313 and the sealing layer 313. The lower part of the sealing layer 313 is a circuit board 322 and a pressure sensor 323. The lead wires 324 are connected to the circuit board 322 and the pressure sensor 323. The lower part of the circuit board 322 is a waterproof and breathable membrane 312. The lower part of the waterproof and breathable membrane 312 is a sealing gasket 311. The sealing gasket 311 is located in the lower part of the housing 33. The lower part of the sealing gasket 311 is a metal sintered sheet 321.

In this embodiment, the connection method between the connecting portions 2 and the valve body 1 is further explained. The connection method between the valve body 2 and the connecting portions 2 can be integrally formed, glued, or threaded.
[0041] Reference Figure 1 , Figure 3 , Figure 5 and 6 The two connecting parts 2 can be connected to each other or set separately. In this embodiment, the two connecting parts 2 can be connected in one piece or set separately.
[0042] Reference Figure 1 Figure 3 and Figure 5 The two connecting parts 2 may be located on the same side or on different sides. In this embodiment, when the two connecting parts are set separately, the two connecting parts 2 may be located on the same side or on different sides, depending on the usage requirements.

The power supply is also common knowledge in the field.
