Description

Technical Field

[0001] This invention belongs to the field of building electromechanical equipment installation, and specifically relates to a valve and gauge assembly device that eliminates the need for manholes. Background Technology

[0002] Currently, residential and public buildings commonly use independent water pipe shafts to arrange risers, branch pipes, valves, and metering instruments. This traditional model has the following prominent technical pain points: First, it has low construction efficiency and high overall cost. The pipeline paths in traditional pipe shafts are long and complex, requiring individual pipe connections, point-by-point fixing, and section-by-section insulation. This results in long construction cycles, cumbersome procedures, and difficult operation, and is greatly affected by the operator's skills, leading to poor installation quality stability. Second, it is difficult to operate and maintain. The operating space in pipe shafts is small, valves and instruments are easily obstructed, making later maintenance and replacement difficult. There is also significant interference between households, and coordination for the renovation of old communities is difficult. Third, it has a low degree of standardization. Due to differences in apartment types, the installation layout of pipe shafts varies, making it difficult to achieve modular assembly and resulting in resource waste. Fourth, it has low space utilization. Due to the influence of the building envelope and operational needs, traditional pipe shafts occupy a significant amount of public space, which is in stark conflict with the demand for high usable floor area in buildings. At the same time, releasing core public space would effectively improve the quality of the building.

[0003] While some existing technologies offer prefabricated and integrated pipe installation solutions, most remain at the level of simple pipeline optimization. They fail to form a truly integrated, modular, multi-pipeline simultaneous installation solution that eliminates the need for manholes, thus failing to fundamentally address core issues such as the large space occupied by manholes, complex construction, and cumbersome operation and maintenance. Therefore, achieving highly adaptable prefabricated "floor pipe, valve, and meter" installation has become a pressing technical challenge for the building installation industry.

[0004] This invention provides an integrated modular valve and meter assembly device, employing an innovative design concept that replaces independent pipelines with system channels. This fundamentally solves the existing technical problems and brings a breakthrough innovation to the installation of "floor pipe valves and meters" in new construction projects, especially in the renovation of existing buildings. Simultaneously, the "assembly pipe" design concept proposed in this invention opens up a completely new application scenario for integrated pipeline installation. This device has significant advantages such as high application efficiency, low overall cost, superior building quality, and standardized implementation, making its application prospects very broad. Summary of the Invention

[0005] This invention aims to provide a valve and meter assembly device that eliminates the need for manholes. Through a modular valve and meter assembly structure design, it achieves rapid installation, stable quality, and strong adaptability. The device uses prefabricated installation, replacing traditional single-pipe connection construction, effectively solving problems such as high labor costs, low work efficiency, and unstable construction quality in existing construction methods. It also achieves significant space savings, eliminating the traditional manhole setup and retaining only riser space. The device uses floor-mounted installation, significantly improving the utilization rate of building public space. Furthermore, this invention is widely adaptable to both new and existing building processes, highly compatible with existing underground pipe technology, and only optimizes the content of public manholes without altering the original underground pipe design, efficiently solving the challenges of water system renovation in old buildings.

Water meters are connected and installed on the water supply and reclaimed water pipes, and meters are connected and installed on the heating water supply pipes.

[0014] Preferably, the valve assembly uses flanges, rubber ring seals, sockets, clamps, threaded connections, or unions to achieve a sealed and leak-proof connection between the pipeline and valve components; the riser assemblies are connected by a butt joint seal, and to increase stability, flanges or clamps are added at the butt joint seal position for further sealing and fixing.

[0015] Preferably, the cover, the rear assembly box and the opening of the rear assembly box are sealed with tongue and groove joints, sealing rings, glands and other methods to form a heat insulation cavity, so as to achieve anti-condensation and heat insulation.

[0016] A construction method for a well-free building assembly structure includes the following steps: S1: Prefabricate integrated modules in the factory, including riser assembly, valve and gauge pre-assembly assembly and part of valve and gauge post-assembly assembly; S2: Heat-melt the four protruding ends of the valve gauge rear assembly and heat-melt them into the radial channels one, two, three and four of the valve gauge front assembly.

S8: Repeat steps S2-S7 layer by layer to complete the installation of the valve and meter assembly for the entire building, which includes the installation of the raw water pipe well.

[0017] The beneficial effects of this invention are: 1. This invention innovatively adopts a system channel design to replace independent pipes. That is, multiple channels are prepared in a solid cylinder to form an assembly pipe for transporting and conveying substances with different functions. Based on the highly integrated design, the original manhole installation only requires a small area of ​​wall and floor space, thereby eliminating the need for manhole construction, simplifying the construction content and freeing up installation space.

[0018] 2. In this invention, multi-diameter and multi-directional channels can be prepared inside the assembly tube to meet different conveying and transmission requirements such as branching and turning; cavities are prepared between each channel to achieve heat insulation and save solid raw materials; partitions formed between each cavity are used to support each channel; and the channels are staggered and do not interfere with each other to meet the needs of mold manufacturing.

[0019] 3. This invention adopts the core design concept of a multi-channel assembly pipe. By expanding the specifications and length of the straight section of the assembly pipe (without radial branch channels), a trunk pipe assembly can be formed to meet the needs of centralized layout of building main pipes. By compressing the length of the assembly pipe and specifically adjusting the diameter, direction and opening angle of the branch channels, special pipe fittings such as straight sections, elbows, and tees can be formed to meet the functional requirements of pipeline continuation, turning and branching.

[0020] 4. In this invention, a hot-melt plug-in connection with an adapter is used at the outlet of the assembly pipe to meet multiple connection types; in the connection of the assembly pipe, a curved joint is used to adjust the pipe height and spacing to shorten the length of the prefabricated parts and expand the working space; the connection between each assembly pipe is completed by flanges, butt joints and double seals to complete the direct connection between pipes or the continuation of pipe fittings; the connection between the assembly pipe and the upstream and downstream uses a flexible hose with a union to adapt to the connection of different heights and spacings of the upstream and downstream.

[0021] 5. In this invention, branch pipes, valves, and meters are housed within a prefabricated, insulated enclosure to meet the requirements of insulation and concealed installation. The enclosure is divided into multiple independent chambers by partitions, with pipes of similar medium temperatures arranged adjacently and housed within the same chamber to reduce energy loss due to temperature differences. Supports are provided within the enclosure to stabilize the pipes and valve components. The enclosure's seams, such as the cover, inspection windows, and openings, are sealed using tongue and groove joints, sealing rings, and glands to prevent condensation and provide thermal insulation.

[0022] 6. This invention adopts a valve and meter assembly device for each household, which increases the speed and convenience of installation and reduces inter-household interference in operation and maintenance; the installation method of assembling for each household meets the needs of various types of civil buildings with different numbers of households; the factory-manufactured finished assembly device meets the replacement needs of complete assembly and disassembly, effectively reducing costs and improving efficiency, and is low in dust and noise, making it very suitable for old building renovation projects. This invention fundamentally solves the technical challenges of existing pipe well installation, bringing groundbreaking innovation to the installation of "floor pipe valves and meters" in new construction projects, especially renovation projects. Simultaneously, the "comprehensive pipe assembly" design concept proposed in this invention creates a completely new scenario for integrated pipeline installation. This device possesses significant advantages such as high construction efficiency, low overall cost, easy operation and maintenance, superior building quality, and standardized production and implementation, making its application prospects very broad.

[0025] In the following text, reference will be made to the appendix. Figure 1-5 An embodiment of a well-free valve assembly device according to the present invention is described.

[0026] The embodiments described herein are specific implementations of the present invention, used to illustrate the concept of the invention, and are illustrative and exemplary, and should not be construed as limiting the implementation or scope of the invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0027] The accompanying drawings in this specification are schematic diagrams to aid in illustrating the concept of the invention, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly demonstrate the structure of the components in the embodiments of the invention, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0028] The following is a detailed explanation of the terms used in this application's technical solution to facilitate understanding of the solution: Nouns: assembly pipe, channel, cavity, branch, riser assembly, connection, valve assembly (pre-valve assembly, post-valve assembly), housing, valve system; Assembly pipe: Transforms the traditional independent pipe installation into a composite integral molding in a single entity, serving as an integrated device for multi-system transportation; assembly pipe is applicable to riser assemblies and valve / gauge pre-assemblies; assembly pipe is made of materials that are hygienic, easy to process, and facilitate connections, such as random copolymer polypropylene.

[0029] Channels: Multiple channels are prepared inside the assembly tube to transmit different functional media such as heating, water supply, and greywater. After subsequent technical verification, the channels can also be used to transmit electrical wires, optical fibers, or a combination of water and electricity.

[0030] Cavities are created between the channels. After construction and installation, these cavities are closed, and the air inside is in a non-flowing state, thereby achieving the function of heat insulation. The partitions between the cavities and channels provide support and stability for the internal structure of the assembly tube.

[0031] Branching, along the solid body, creates radial channels that connect the axial channels, achieving the function of media branching and transportation; Connection Design: This includes branch connections of the main assembly pipes, connections between adjacent main assembly pipes, and connections between the valve / gauge assembly and external components. Branch Connections of Main Assembly Pipes: The ends of the branch pipes in the main assembly are socket-type, and the downstream pipes are connected via heat fusion splicing. Connections Between Adjacent Main Assembly Pipes: Adjacent main assembly pipes are connected using flanges, rubber ring seals, sockets, clamps, snap-fit ​​connections, threaded connections, or unions to achieve a simple and quick unified connection across multiple channels. The radial channel diameter must be less than or equal to the axial channel diameter. Connections between the Valve / Gauge Assembly and External Components: This includes connections to the upstream main pipe and to the downstream inlet pipe, using flexible hoses. Specific connection structures and principles are as follows (including but not limited to the methods described below). 1. Flange-type composite sealing connection The assemblies are connected to each other and to fittings using a grooved snap-fit ​​connection. Compared with traditional threaded or flanged connections, this effectively solves the problems of insufficient operating space and difficulty in docking in confined spaces. External clamps or pipe clamps are used to achieve overall fastening and ensure the stability of the connection structure.

[0032] The internal functional channels adopt a composite sealing structure of male and female fitting + flange water stop line + sealing rubber ring. The male and female fittings make the multiple channels accurately coaxially aligned, avoiding media leakage caused by channel misalignment. The sealing rubber ring is embedded in the flange water stop line to form a double sealing barrier, completely eliminating the hidden danger of internal pipeline leakage. The whole is fixed by clamps or pipe clamps, achieving the dual effect of quick connection and sealing and seepage prevention.

[0033] 2. Snap-lock type quick-locking connection The connection structure includes symmetrically arranged left and right connectors, as well as a middle sealing transition sleeve and a butt joint structure. Each internal functional channel is equipped with a dedicated impact sealing device, and the contact end face at the connection point is machined with a double annular sealing groove. A fluororubber sealing gasket is installed inside the annular sealing groove, forming a multi-level integrated sealing system to ensure sealing reliability. At the same time, it is equipped with annular quick-locking clamps and circumferential positioning pins, which can not only achieve rapid overall locking of multiple channels, but also precisely define the connection position, ensure the coaxiality of the channels after docking, and improve connection efficiency and structural accuracy.

[0034] 3. Sealing connection structure with limiting components, sliding grooves, and clamps. The riser assemblies are installed sequentially from bottom to top. Adjacent riser assemblies are connected by a limiting structure at the end of the riser assembly. The lower port of the upper riser assembly is laterally moved to the limiting termination point through the slide within the limiting structure. Then, it is secured with bolt clamps through a flange structure with a sealing ring on the interface surface of the riser assembly. The advantages of this method are that parallel moving installation makes it easier to align the channels within the connected riser assemblies, the limiting component can prevent pipe misalignment, and the sealing flange structure can improve the pipe sealing performance.

[0035] In addition, considering the protection of diverse connections, connection methods such as socket joints, heat fusion, threaded connections, or live joints are reserved. Any connection method that can be applied to this invention should fall within the protection scope of this invention.

[0036] Valve and gauge assembly: including the front assembly and the rear assembly.

[0037] Housing: The housing of the valve gauge assembly is made of a material with strength and thermal insulation properties, such as modified EPP.

[0038] Valve and gauge system: The rear assembly housing contains control switches, flow valves, metering gauges, functional components, and corresponding piping and fittings, as well as fixed supports. Example 1

[0039] A valve assembly device that eliminates the need for a manhole includes a riser assembly 12, a pre-valve assembly 1, and a post-valve assembly. The riser assembly 12 and the pre-valve assembly 1 have similar structures and are prefabricated integral parts. The whole is cylindrical, with multiple axial channels along the long axis and radial channels corresponding to and communicating with the axial channels. Multiple sets of riser assemblies 12 are sealed and seepage-proof connected to each other. The riser assembly 12 and the pre-valve assembly 1 are sealed and seepage-proof connected to each other through connecting pipes. Multiple sets of pre-valve assemblies 1 are sealed and seepage-proof connected to each other through connecting pipes. The pre-valve assembly 1 and the post-valve assembly are sealed and seepage-proof connected to the inlet pipe through connecting pipes. The post-valve assembly is sealed and seepage-proof connected to the inlet pipe through a flexible hose. This solution combines multiple pipes in the water manhole to form an integral prefabricated structure, i.e., an assembly. During installation, the assembly structure is hoisted as a whole, which can greatly reduce the water manhole space required in the prior art and reduce the labor cost of the original water manhole assembly.

[0040] Example 2: This embodiment employs a multi-channel assembly pipe core design, complemented by designs for extension, turning, and branch pipe fittings, as well as designs for the connection between the assembly pipe and fittings. Based on the basic structure of the assembly pipe of this invention, by expanding the specifications and length of the straight section of the assembly pipe, an integrated module for building trunk pipelines can be directly formed to meet the centralized layout requirements of building main pipelines; by compressing the length of the assembly pipe and specifically adjusting the diameter, opening angle, and direction of the branch channels, specialized fittings for extension, turning, and branching can be formed without the need for additional splicing of multiple independent pipe sections. The specific structure includes the valve pre-assembly installed on the wall (floor). In this example, the valve pre-assembly is a cylinder with axial channels 1 (2), 2 (3), 3 (4), and 4 (5) axially staggered and extending through it. Axial channels 1 (2) and 2 (3) have radial channels 1 (6) and 2 (7) respectively on the same side, leading to their exits. Axial channels 3 (4) and 4 (5) have radial channels 3 (8) and 4 (9) respectively on the same side, leading to their exits. The four axial channels and four radial channels are arranged at intervals. A cavity 10 is provided between the channels, and a partition 11 is provided between the cavities; a riser assembly 12 is provided on the upstream side of the first valve assembly, which is connected to the axial channel 1 2, axial channel 2 3, axial channel 3 4 and axial channel 4 5 respectively; the valve assembly includes a rear assembly housing 14 provided on the radial channel outlet side of the valve assembly; the front side of the rear assembly housing 14 has four protruding ends 13, which are respectively inserted and connected to the radial channel 1 6, radial channel 2 7, radial channel 3 8 and radial channel 4 9 respectively; a rear assembly cover 15 is provided on the upper part of the rear assembly housing 14.

[0041] The assembly pipes and fittings, as well as the assemblies themselves, adopt a diversified and quick connection structure. With a single, simple operation, four or more channels can be connected and installed simultaneously, completely changing the cumbersome construction mode of connecting and fixing single pipes one by one in stages, and greatly simplifying the installation process.

[0042] Example 3: This embodiment utilizes curved joints at the branch outlet of the front assembly to adjust the spacing and height of each pipe, ensuring both device integration and sufficient space for the installation and maintenance of water meters and valve components. Furthermore, leveraging the adaptability of flexible hoses, the valve assembly is connected to upstream and downstream systems. The valve system within the rear assembly primarily uses heat fusion and threaded connections; the short pipe connected to the front assembly is converted to a threaded connector via an adapter. Curved joints, valves, and sludge separators are then installed sequentially. Subsequent meter and hose installation is performed on-site, ultimately connecting to the downstream inlet pipe via a flexible hose. Valve components located on the outer side of the rear assembly housing are installed at an angle, allowing operation through the housing's maintenance window. Curved joints are used to adjust the system's installation space, such as adjusting the outlet pipe height and widening the pipe spacing, to shorten the overall pipe length and expand the working space. This approach allows for a smaller overall assembly size, a wider selection of meters and valve components, and easier connections to upstream and downstream systems.

[0043] Example 4: The valve assembly housing is divided into two parts: the bottom and the top. Inside, a vertical insulation plate divides the housing into two chambers. Two pipes with similar temperatures are grouped together, such as one group for heating supply and return water, and another group for water supply and reclaimed water, which are placed in the two chambers respectively. The side panels of the housing are designed for detachable assembly, and windows for operating valves and maintaining the dirt separator are provided on the sides of the housing. Gaps and openings at the top and bottom of the housing, such as pipe outlets and operating windows, are sealed using tongue and groove joints, compression caps, and flexible joints. The housing contains components for pipe support. The flexible hose at the end of the pipe connected to the household pipe can move inside and outside the housing outlet.

[0044] Note: The pipeline structure in the technical solutions included in this invention adopts an optimized layout design approach. To address the issue of "pipes being blocked" within the assembly, a staggered layout is adopted: to prevent one of the four pipes from exiting the assembly, the pipelines are designed in different forms, such as straight lines or curves, according to site requirements during the manufacturing process (casting / extrusion, etc.), while also taking into account hydraulic losses, to ensure smooth pipe routing for all pipelines.

[0045] Layout according to usage frequency: Place the least frequently used greywater pipes behind unfavorable locations, prioritize the layout of heating and water supply pipes, and arrange water meters according to the metering requirement of "10 times the pipe diameter in a straight line before and 8 times the pipe diameter after".

[0046] In summary, this valve and meter assembly device, which eliminates the need for manholes, significantly shortens the construction cycle through its modular structure. The integrated, interconnected installation replaces the traditional method of connecting individual pipes, adapting to the current high labor costs, low efficiency, and inconsistent quality of construction projects. It also saves space by eliminating traditional manholes and retaining only the space for risers, allowing for floor-mounted installation and improving building utilization. Furthermore, it is compatible with new building construction techniques, perfectly fitting current underground pipe systems. Optimization is only applied to manholes in public spaces, without altering the original underground pipe design, greatly solving the challenges of water system renovation in older buildings.

[0047] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention to achieve the purpose of the invention.
