Description

Technical Field

[0001] This utility model relates to the field of valve structure installation technology, and more specifically, to an external liner for a water valve embedded in a building wall. Background Technology

[0002] Existing shower valves typically require connection to both cold and hot water pipes. For aesthetic reasons and to save space, most families opt for concealed installation, embedding the piping system and valve within the wall. After installation, only the shower control panel and overhead showerhead are visible on the wall, resulting in a neat and aesthetically pleasing appearance.

[0003] There are two ways to connect the piping system and the water valve. One is to directly screw the pipe to the water valve interface, with the threads interlocking. However, this method makes it difficult to guarantee a tight seal, so multiple layers of PTFE tape are often wrapped around the connection. This makes the installation relatively complex, and the internal and external threads of the pipe and water valve are prone to water hammer, resulting in significant noise. The other method is heat fusion connection, where the water valve interface is made of plastic, and the pipe is directly heat-fused to the interface, forming a single structure. Regardless of the method, the water flow enters the water valve at a bend, and the internal space is reduced, increasing water pressure and the impact force of the water flow, making the noise particularly noticeable. When the water valve is installed internally in the wall, the noise is amplified by the sound flow being conducted within the wall, significantly affecting the user experience and causing inconvenience. Utility Model Content

[0004] The technical problem to be solved by this utility model is that sound noise is transmitted in the wall, amplifying the noise and affecting the user experience. In view of the problems existing in the prior art, an external lining for a water valve embedded in the building wall is provided.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: an external lining for a water valve embedded in a building wall, comprising:

[0006] The outer shell includes a first shell and a second shell, wherein the first shell is disposed within the second shell to form a double shell, and a cavity is provided between the two shells, and a filling layer is provided within the cavity;

[0007] The outer end of the outer casing is provided with several external openings;

[0008] The housing has an installation area inside, and the installation area has several partition areas from the outside to the inside. Each partition area has several partition components, and there are connecting components between the partition components. A sound-absorbing cavity is formed between the partition components and the connecting components. A sound-absorbing plate is provided in the center of the installation area.

[0009] The first housing for the water valve prevents the concrete structure of the inner wall from wearing down the valve, and the filling layer and sound-absorbing cavity reduce the noise during water flow.

[0010] A further preferred embodiment: the filling layer includes sound insulation cotton and filling adhesive, and the sound insulation cotton is close to the first housing. There is a concave-convex connection position between the sound insulation cotton and the filling adhesive. The outer side of the sound insulation cotton close to the first housing can be installed by adhesive bonding. The concave-convex connection design can ensure the connection between the sound insulation cotton and the filling adhesive.

[0011] A further preferred embodiment: the length of the external passage is ≥3cm, and the outer surface of the external passage is provided with an opening. The external passage is a semi-closed structure. With this design, the water valve can be installed while the pipe is placed in the wall, and the pipe enters from the opening of the external passage.

[0012] The outer opening is provided with a sealing element at one end near the outer shell. The connection position between the sealing element and the outer opening has several intermittently arranged through grooves. The sealing element is disassembled along the through grooves, and the outer opening communicates with the installation area.

[0013] A further preferred embodiment: the mounting surface of the mounting area is flat or curved; the partition is curved, and the height of the multiple partitions decreases sequentially from the outer ring to the inner ring; in this design, the shape of the mounting surface of the mounting area is adapted to the back structure of the water valve.

[0014] A further preferred embodiment: the gap between the partition members in the same ring is a spacer channel, and an annular groove is provided on the outer periphery of each ring of partition areas, with the spacer channel and the annular groove communicating with each other;

[0015] The diameter of the annular groove decreases from the outside to the inside, forming a sound-absorbing cavity.

[0016] A further preferred embodiment: the connector is connected between two corresponding inner and outer partitions, or between the adjacent ends of two outer peripheral partitions, and the connector corresponds to the partition channel.

[0017] A further preferred embodiment: the installation space of the installation area is divided into a maze shape by partitions and connectors, and the channel composed of the partition and the annular groove is a sound-absorbing cavity.

[0018] A further preferred embodiment: the connector is fan-shaped, and the partition is made of an elastic polymer material.

[0019] A further preferred embodiment: an outer cover is installed at the outer end of the outer casing;

[0020] The rear end of the casing has several mounting parts, and the surface of the mounting parts has recesses.

[0021] The beneficial effects of this utility model are:

[0022] When the water valve is in operation, one or two pipes in the X-axis direction release water simultaneously. The resulting noise flow is transmitted from the water valve interface to the inside of the water valve body. The installation space in the installation area is divided into a maze shape by partitions and connectors. The transmission path of the noise flow is tortuous. The tortuous sound-absorbing plate can block the noise flow transmitted from multiple directions, thus forming multiple barriers. During the movement of the noise flow, multiple barriers attenuate the noise flow, thereby reducing the noise, reducing living noise, and improving living comfort.

[0023] The transition from the first shell to the second shell requires the use of sound insulation cotton and filler adhesive. These two materials can further reduce noise. The sound insulation cotton is fixed in the cavity by the filler adhesive, and there are concave and convex joints between the sound insulation cotton and the filler adhesive. After the adhesive is applied and solidified, the two are not easy to separate, which can reduce the vibration of sound noise on the second shell, thereby reducing noise again.

Detailed Implementation

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figure 1-8 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples of implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0035] Please see Figure 1 , Figure 2 and Figure 8 An external lining component for a water valve embedded in a building wall, comprising:

[0036] The outer shell 1 includes a first shell and a second shell. The first shell is disposed within the second shell to form a double-layer shell. The first shell has an installation area 2 inside, which is the installation position of the water valve. The overall structure of the outer shell 1 is the outer liner of the water valve. The outer shell 1 is installed into the reserved space in the wall. The rear end of the second shell has several mounting parts 10. The mounting parts 10 can be embedded columns or bolt washers with screw holes. In order to ensure installation strength and not damage the wall structure, it is preferred to use embedded columns. The mounting parts 10 are embedded into the wall. In order to ensure the installation stability of the outer shell 1, the length of the mounting part 10 in the Z-axis direction is at least two-thirds of the thickness of the outer shell 1 in the Z-axis direction. The surface of the mounting part 10 is provided with pits so that the concrete material of the wall can penetrate into the surface of the mounting part 10 when it is not solidified. After solidification, the mounting part 10 is not easy to detach from the wall.

[0037] like Figure 1 and Figure 8 As shown, the outer end of the outer casing 1 is provided with four external openings 101, which are arranged in a cross shape. When installing the outer casing 1, it is necessary to ensure that the four external openings 101 are completely horizontal in both the longitudinal and transverse directions. A sealing element 102 is provided at the end of each external opening 101 near the outer casing 1. The sealing element 102 is designed to prevent concrete from entering the installation area 2. Firstly, according to the number of water valve interfaces, a pipe channel is reserved outside the water valve installation space in the wall (e.g., ...). Figure 8 (As shown) If the water valve has a four-way connector, then the reserved pipe passage should be in a cross shape. If it has a three-way connector, then only the left and right pipe passages in the X-axis direction and the upper or lower pipe passage need to be set. The left and right pipe passages in the X-axis direction are the cold water pipe and the hot water pipe, respectively. (As shown) Figure 1 As shown, the connection position between the sealing part 102 and the external passage 101 has several intermittently arranged through grooves. The sealing part 102 can be disassembled along the through grooves to make the external passage 101 communicate with the installation area 2. The external passage 101 is a semi-closed structure. The water valve and the pipeline are placed in the installation area 2. The pipeline enters the external passage 101 from the opening at the outer end of the external passage 101. This installation method is suitable for hot melt pipes. If it is a threaded connection pipeline, the water valve can be installed in the installation area 2 first, and then the pipeline can be placed in the external passage 101 and the interface with the water valve can be adjusted for connection. The length of the external passage 101 is ≥3cm. The pipeline is guided to extend into the channel reserved in the wall through the external passage 101.

[0038] Even better, the external passages 101 are arranged in a cross shape. The inner diameter of the external passage 101 can be designed to match the outer diameter of the pipe to be installed. When the pipe is placed into the external passage 101, the outer surface of the pipe is close to the external passage 101. The pipe can be positioned through the external passage 101, which restricts the installation in two directions: the X-axis horizontal direction and the Y-axis vertical direction. This eliminates the need for installers to repeatedly level and adjust the position of the pipe and water valve.

[0039] like Figure 1 and Figure 3 As shown, to match the back of the water valve, the mounting surface of the installation area 2 can be designed as a flat or curved surface. The center of the back of the water valve and the mounting surface of the installation area 2 is preferably 5mm apart. The installation area 2 has several partition areas 3 from the outside in. Each partition area 3 has several partition members 301, which are curved. Multiple partition members 301 are arranged in a ring, allowing the water valve to be supported from multiple directions. The height of the multiple rings of partition members 301 decreases sequentially from the outer ring to the inner ring. The height of the partition members 301 in the Z-axis direction can be designed to match the curvature of the back of the water valve. The height difference between the partition members 301 should precisely match the curvature of the back of the water valve body (e.g., ...). Figure 1 (As shown) The inner wall of installation area 2 is equipped with bolt locking plates, which can be used to lock and fix the water valve.

[0040] like Figure 3 As shown, there are connecting pieces 6 between the partition pieces 301. After the water valve is installed, its back will be in close contact with the connecting pieces 6 and the partition piece 301. The connecting pieces 6 are fan-shaped and distributed in a ring. The water valve can be supported by multiple connecting pieces 6, forming multiple fulcrums. Moreover, the contact area between the connecting pieces 6 and the water valve is larger than that between the partition piece 301 and the water valve, which improves the stability of the installation.

[0041] like Figure 1 and Figures 3-5 As shown, furthermore, the gaps between the partition members 301 in the same ring are spacer channels 4, and each ring of partition area 3 has an annular groove 5 on its outer periphery. The spacer channels 4 and the annular grooves 5 are connected (e.g., Figure 3 (As shown) Connector 6 is connected between two corresponding inner and outer partitions 301. The multi-ring groove 5 is the first ring, the second ring, and so on from the outside to the inside. Similarly, the spacer channel 4 is the spacer channel. When one or two pipes in the X-axis direction are released at the same time in the working state of the water valve, the noise generated is transmitted from the water valve interface to the inside of the water valve body. The noise is guided from the outermost ring groove 5 to the outermost spacer channel 4, and then into the second ring groove 5 and the second spacer channel 4, and then inward. The diameter of the ring groove 5 decreases from the outside to the inside, and finally reaches the center of the installation area 2. The meandering sound-absorbing plate 11 can block the noise flow transmitted in multiple directions, thus forming multiple partitions. During the movement of the noise flow, the multiple barriers attenuate the noise of the noise flow, so the noise is reduced, reducing living noise and improving living comfort.

[0042] A better solution, (e.g.) Figure 4 As shown, connector 6 is connected between the two adjacent ends of the two outer partitions 301. Connector 6 has a larger coverage area, and each connector 6 corresponds to the partition channel 4. The outer end space of the annular groove 5 is divided by connector 6, which divides more space than the above scheme. This structure is suitable for use environments with higher noise reduction requirements. Thus, the installation space of the installation area 2 is divided into a maze shape by the partitions 301 and connector 6, and the transmission path of the noise flow is tortuous, which effectively attenuates the noise.

[0043] The above design solves the problem of traditional water valves transmitting noise directly into the wall through the embedded shell, resulting in significant noise. Furthermore, the water valve does not directly contact the outer shell 1. The partition 301 and connector 6 inside the installation area 2 prevent the noise flow from directly impacting the outer shell 1, thus avoiding the transmission of noise from the outer shell 1 into the wall.

[0044] like Figure 6 and Figure 7 As shown, a cavity is provided between the first shell and the second shell, and a filling layer is provided in the cavity. The filling layer includes sound insulation cotton 7 and filling adhesive 8. The sound insulation cotton 7 is close to the first shell, and the sound noise is conducted to the first shell. The transition between the first shell and the second shell requires the sound insulation cotton 7 and the filling adhesive 8 to pass through. The two can reduce noise again. The sound insulation cotton 7 is fixed in the cavity by the filling adhesive 8. There is a concave and convex connection position between the sound insulation cotton 7 and the filling adhesive 8. After the adhesive is applied, it solidifies and the two are not easy to separate. This can reduce the vibration of the sound noise flow on the second shell, thereby reducing noise again.

[0045] Furthermore, the partition 301 is made of an elastic polymer material, preferably rubber. The partition 301 can provide shock absorption on the back of the water valve, and can reduce the vibration transmitted from the water valve to the outer casing 1 more effectively than metal materials.

[0046] Furthermore, an outer cover 9 is installed on the outer end of the outer shell 1. The outer cover 9 is connected and fixed to the outer shell 1 by sealant. The surface of the outer cover 9 has a reserved hole for installing a mixing valve. The outer cover 9 does not need to be buried inside the wall; it can be exposed on the wall surface and level with the wall surface.
