Description

Technical Field

[0001] The utility model relates to the technical field of manifolds, and in particular to a modular plastic manifold. Background Art

[0002] A manifold is a device used to connect the main water supply pipe and return pipe of the heating system in the floor heating system. It is divided into two parts: a manifold and a manifold. A manifold is a water distribution device used to connect the water supply pipes of various heating pipes in a water system. A manifold is a water collection device used to connect the return pipes of various heating pipes in a water system. In recent years, due to people's control of costs, consideration of installation space, limitations of application scenarios and the demand for multi-functional integration, the existing manifold configuration has been increasingly neglected by customers. There is an urgent need to design a manifold with low cost, small size, full functions and comprehensive integrated coverage. At present, the manifolds supplied in the market are divided into copper, stainless steel and plastic manifolds. Copper manifolds are not popular with customers because of problems such as easy oxidation, scaling, and valve core jamming. If stainless steel manifolds are used in radiant cooling, the additional cost of insulation and the problem of condensed water have always been a headache for customers. There are also many plastic manifolds on the market, with diverse application scenarios and relatively low costs, but the assembly accessories have not yet achieved full plastic insulation, and they occupy a large space and have a single function, which cannot fully meet the integrated and multi-functional expectations of customers.

[0003] The shortcomings / deficiencies of existing plastic manifolds are as follows:

[0004] 1. Existing plastic manifolds: The manifold assembly is separate from the manifold assembly, the water supply and return lines are highly staggered, and more space is required on the numerous adapters to install, so a significantly larger manifold outer box is required for installation. The product is large in size, occupies a wide space, and has low installation efficiency and is inconvenient;

[0005] 2. Some parts of the existing plastic manifold are made of metal, which cannot completely achieve the effect of heat preservation and avoid condensation water when used in radiation cooling;

[0006] 3. The temperature gauges are respectively set on the water supply and return ports of the water distributor and the water collector. They can only monitor the water temperature in the water supply and return pipes, but cannot monitor the return water temperature of a single branch, and cannot adjust the stability of the temperature of a single branch.

[0007] 4. The existing plastic manifold has a relatively simple connection with the main pipeline. It can be installed and connected horizontally, but not vertically. It requires additional accessories for connection. Horizontal connection is the norm and cannot meet customers' multi-directional installation needs;

[0008] 5. The existing plastic manifold mounting bracket has a fixed depth and cannot be adjusted, and is not suitable for specific wall installations and applicable scenarios. Utility Model Content

[0009] The purpose of the present invention is to design a new modular plastic manifold in response to the problems of existing products and customers' demand for product integrated space. This new modular manifold is small in size, highly functional, and easy to install, and can meet customers' various installation needs.

[0010] To achieve the above object, the present invention adopts the following technical solution:

[0011] A new type of modular plastic manifold, mainly composed of several distribution modules, left connection modules, right connection modules, screws, mounting brackets and other parts. Among them, several distribution modules, left connection modules and right connection modules are closely arranged in the longitudinal direction of the module and are connected by two screws passing through and locking.

[0012] The distribution module is designed with two parallel horizontal channels that are connected on both sides. The channel at the rear side is the water supply channel, and the channel at the front side is the return water channel. The two are independent spaces and do not intersect with each other. The middle part of the water supply channel bends downward and extends to form a water supply connection, and bends upward and extends to connect the flow regulating valve. The water supply connection and the flow regulating valve cooperate with each other to adjust the flow size of the branch; the return water channel bends downward and extends to form a return water connection, and a stop valve is set at the bend extension. The return water connection and the stop valve cooperate with each other to achieve the closure of the return water of the branch. The water supply connection and the return water connection are connected through the floor heating pipe when the whole system is assembled. The water supply connection is the water inlet end, and the return water connection is the return water end; in addition, the water supply connection and the return water connection are offset from each other on the longitudinal axis, that is, the offset is nearly half the distance of the heating circuit. At the same time, the water supply connection extends longer than the return water connection. The special space arrangement is conducive to the convenient installation of the adapter. A thermometer is set in front of the distribution module to monitor the temperature of the return water of the branch at any time.

[0013] The left connection module is also provided with two parallel channels, wherein the pipe 1 on the rear side is connected with the water supply channel of the branch module, and the other end thereof is connected with the left water inlet, and the upper side of the channel is connected with the exhaust valve; the pipe 2 on the front side is connected with the return water channel of the branch module, sealed to the left, and extends downward at the seal to form a channel for the left return water connection, and extends upward at the seal to form a channel connected with the drain valve, the drain valve is a nut joint connection, and is easy to install, and an outlet arrow mark is provided in front of the outer surface of the left connection module, so that the installer can clearly understand the position of the inlet and outlet;

[0014] The right side connection module is also provided with two parallel channels, wherein the pipe 3 on the rear side is connected with the water supply channel of the branch module, connected to the right side water inlet to the right, and extends upward to form a channel connected to the drain valve; the pipe 4 on the front side extends to the left and is connected with the return water channel of the branch module, is sealed to the right, and extends downward at the seal to form a channel for the right side return water connection, extends upward at the seal to form a channel connected to the exhaust valve, and an arrow mark of the water outlet is designed in front of the outer surface of the right side connection module, so that the installer can clearly understand the position of the water inlet and outlet;

[0015] The drain valve and exhaust valve are installed on the water supply pipeline and return pipeline formed by the left connecting module, several distribution modules and the right connecting module. The exhaust valve is mainly used for the discharge of gas in the system, which is beneficial to the stability of the water supply system and the return system. The drain valve mainly has the functions of injection and discharge for pipeline cleaning.

[0016] The diversity of installation positions of the novel modular plastic manifold mainly refers to: when the customer's water inlet and return are at the left front end or the lower left, the left water inlet connection of the left connecting module is quickly connected with the straight connecting pipe fitting or the elbow connecting pipe fitting by using a plug, and the left water return connection and the elbow connecting pipe fitting or the straight connecting pipe fitting are also quickly connected with a plug, while the right water inlet connection and the right water return connection of the right connecting module are quickly connected with a plug plug; when the customer's water inlet and return are at the right front end or the lower right, the straight connecting pipe fitting and the elbow connecting pipe fitting installed on the left connecting module are connected with the two plugs on the right connecting module by interchangeability, thereby achieving diversity of installation positions.

[0017] The mounting bracket is formed by bending a stainless steel plate at 90 degrees. One side is fitted to the left connection module and is designed as a U-shape. A straight notch is designed on the fixing surface. The notch is inserted into the screw rod and then fixed with a flat washer and a nut. A decorative cap is installed on the nut for beautification. The other side is parallel to the wall. Insulating plates are installed at the fixing holes at both ends to prevent shock and static electricity. The fixing holes are designed as upper and lower notches and left and right notches to facilitate the adjustment of the plastic manifold during installation. The straight notch can be moved forward and backward on the screw rod for adjustment. After the position is adjusted, it is locked and fixed with the screw rod. The other mounting bracket is installed on the right connection module. The distance of the two mounting brackets can be adjusted separately. Therefore, this mounting bracket can variably adjust the depth of each module to the wall, especially as large as possible, thereby creating a higher level of installation comfort.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention is a novel modular plastic manifold with a compact and modular design. The water supply channel and the return water pipeline are designed in one module, so the structure is compact, the volume is small, and the installation area is small.

[0020] This modular plastic manifold is a water supply and return circulation rule formed by each module connected by thread or insert-type snap-on connection. The customer's demand for branches can be met by increasing the number of distribution modules.

[0021] In the module, the water supply channel runs at the rear and the water return channel runs at the front, forming a rear supply line and a front water return line configuration; the water supply connection and flow regulating valve on the distribution module and the water return connection and stop valve on the distribution module are offset from each other on the longitudinal axis, that is, offset by nearly half the distance of the heating circuit, to prevent interference with each other during the installation of the adapter, making it difficult to install; the water supply connection extends longer than the water return connection. Since the water supply connection extends longer, these connections can be easily accessed during the assembly process. The special spatial arrangement is conducive to the convenient installation of the adapter;

[0022] A flow regulating valve is set at the upward extension of the water supply channel of the distribution module, which can control the flow to adjust the temperature of the branch. At the same time, a stop valve is set at the upward extension of the return water channel of the distribution module. The function of this stop valve is to manually / automatically close the water flow when the branch temperature reaches the set value to prevent waste of resources;

[0023] A thermometer is provided in front of the distribution module to monitor the return water temperature of the branch at any time; a drain valve for injection or drainage and an exhaust valve for exhausting system air can be installed on the left connection module and the right connection module.

[0024] The interface between the left and right connection modules and the main pipeline is a plug-in connection, which is quick and convenient, greatly improving the installation efficiency;

[0025] The arrow marks of water outlets are designed in front of the left and right connection modules, so that the installer can clearly see the positions of water inlet and outlet;

[0026] The left and right connection modules are designed with connection interfaces with the main pipeline inlet and return lines. In actual installation, if the supply and return water are on the left, the right connection module interface is closed with a plug, and vice versa. If the inlet and return water are horizontal or vertical, they can be connected by using straight connecting pipes or curved connecting pipes, which greatly increases the diversity of installation, while reducing the transfer of other accessories and reducing the use space of the equipment;

[0027] The mounting bracket is installed on the left and right sides of the connecting module and fixed on two screws. The bracket is designed with straight notches at the screw fixing position, which can adjust and guide the length of the mounting bracket, that is, the depth adjustment from the manifold module to the wall is achieved, and it can also meet the installation requirements of different wall convexities and concavities. An insulating plate is added at the fixing position of the mounting bracket and the wall screws to prevent shock and static electricity.

[0028] The left connection module, distribution module and right connection module are all injection-molded rectangular shells. The water supply channel line and the water return channel line formed by their close connection through screws are isolated. Relative to the external rectangular shell, a corresponding air chamber is created inside, which has a certain degree of thermal isolation. Especially when the product is used in radiation cooling, it also has the function of preventing condensation water. BRIEF DESCRIPTION OF THE DRAWINGS

The exhaust valve is mainly used for the discharge of gas in the system, which is beneficial to the stability of the water supply system and the return system. The drain valve mainly has the functions of injection and discharge of liquid for pipeline cleaning.

[0045] The diversity of installation positions of the novel modular plastic manifold mainly refers to: when the customer's water inlet and return are at the left front end or the lower left, the left water inlet connection 20 of the left connecting module 2 is quickly connected to the straight connecting pipe fitting 15 or the elbow connecting pipe fitting 16 by means of a plug 18, and the left water return connection 21 is also quickly connected to the elbow connecting pipe fitting 16 or the straight connecting pipe fitting 15 by means of a plug 18, while the right water inlet connection 22 and the right water return connection 23 of the right connecting module 3 are quickly connected by means of a plug 17 by means of a plug 18; when the customer's water inlet and return are at the right front end or the lower right, the straight connecting pipe fitting 15 and the elbow connecting pipe fitting 16 installed on the left connecting module 2 are connected interchangeably with the two plugs 17 on the right connecting module 3, thereby achieving diversity of installation positions.
