Description

Technical Field

[0001] The invention belongs to the technical field of water distributors, and in particular relates to a steady-flow water distributor valve and a water distributor. Background Art

[0002] The manifold of floor heating is a water distribution and collection device used to connect the supply and return water of various heating pipes in the water system.

[0003] Generally, the water distributor includes an inlet pipe, a return pipe and several water distribution pipes, and the two ends of each water distribution pipe are connected to the inlet pipe and the return pipe respectively; each water distribution pipe is zigzag to different heating spaces. Due to the different sizes of different heating spaces, the heat exchange time of the thermal fluid in the water distribution pipe in the heating space will also be different. If the thermal fluid in each water distribution pipe maintains the same flow rate, there will be problems such as inconsistent temperatures in each heating space and low heat exchange efficiency of the thermal fluid.

[0004] In order to solve this problem, a Chinese utility model patent with publication number CN204986158U discloses an electric water diverter valve mounting structure of a water diverter, wherein the water diverter includes a water inlet pipe and a plurality of water diverter pipes connected to the water inlet pipe; the electric water diverter valve mounting structure is arranged on each water diverter pipe, including a mounting seat fixed on the side of the water diverter pipe, the mounting seat is provided with a through hole for a valve stem of a valve core assembly arranged in the water diverter pipe to pass through, an electric driver is detachably fixedly connected to the mounting seat, and when the electric driver is mounted on the mounting seat, the valve stem is connected to the electric driver and the valve stem can rotate under the drive of the electric driver.

[0005] The disadvantage of the installation structure of the electric water diverter valve is that due to the limitation of the structure in which the water diverter pipe and the water inlet pipe are integrated in the traditional water diverter, when installing the water diverter valve, it is necessary to open a through hole on the water diverter pipe for the valve stem to pass through, and it is also necessary to provide a sealing structure at the through hole, which not only increases the difficulty of manufacturing the water diverter, but also requires the valve core assembly to be installed from the water outlet end of the water diverter pipe to the bottom of the through hole, which is very troublesome to assemble and not conducive to maintenance and replacement. Summary of the invention

[0006] The object of the present invention is to provide a steady flow water diverter valve and a water diverter which are easy to install and disassemble.

[0007] To achieve the above-mentioned object of the invention, the technical solution of the present invention is as follows:

[0008] A steady-flow water diverter valve comprises a valve body, wherein a first water inlet channel with a water inlet and a first water outlet channel with a water outlet are formed in the valve body, and the water inlet and the water outlet are on the same axis; a buffer cavity connecting the first water inlet channel and the first water outlet channel is also formed in the valve body, and the axis of the buffer cavity is perpendicular to the axis of the water inlet and the water outlet; a connecting hole is formed between the buffer cavity and the first water outlet channel, and a valve core assembly for adjusting the opening and closing state of the connecting hole is provided in the valve body.

[0009] The steady-flow water diverter valve of the present invention has a separate valve body, and the valve body and the valve core can achieve an expected sealing state. When in use, it is only necessary to connect the water inlet of the valve body to the water inlet pipe of the water diverter, and connect the water outlet of the valve body to the water diverter pipe of the water diverter. The entire installation and disassembly process is very simple and quick, and the sealing connection between pipelines is also more labor-saving.

[0010] The steady-flow water diverter valve of the present invention is provided with a buffer chamber. The hot fluid entering from the water inlet pipe first flows slowly through the buffer chamber before entering the water outlet channel, ensuring that the hot fluid entering the water diverter pipe does not rush, thereby making the heat exchange efficiency of the hot fluid in each heating-requiring space higher.

[0011] In the above-mentioned steady flow water diversion valve, the valve core assembly includes a valve core slidably installed in the buffer cavity, the tail end of the valve core has an outer flange that seals with the inner wall of the buffer cavity, and the head end of the valve core has a valve head that matches the connecting hole; at the tail end of the valve core, a driving unit for driving the valve head away from or blocking the connecting hole is installed in the valve body, and a limiting step that abuts against the outer edge of the opening of the connecting hole is formed between the valve core and the valve head. Providing an outer flange that seals with the inner wall of the buffer cavity can reduce the outer diameter of the valve core body, leaving more buffer space for the buffer cavity. The limiting step is to limit the maximum stroke of the valve head movement.

[0012] In the above-mentioned steady-flow water diversion valve, a return spring is abutted between the outer flange and the outer edge of the opening of the communicating hole, and the return spring can assist the valve head to move away from the communicating hole.

[0013] In the above-mentioned steady flow water diverter valve, a notch is formed on the valve head for connecting the buffer cavity and the first water outlet channel, and the opening of the notch gradually becomes smaller from one end of the valve head toward the connecting hole to the end away from the connecting hole. After the notch is set, even if the valve head is incorporated into the connecting hole, the hot fluid in the buffer cavity can still enter the first water outlet channel from the notch, and as the depth of the valve head is increased, the flow of the hot fluid entering the first water outlet channel becomes less and less until it is zero. Compared with a valve head in a complete cylindrical shape, this valve head structure is more conducive to regulating the fluid flow through the water diverter valve.

[0014] Preferably, in the above-mentioned steady-flow water diverter valve, the notch has a triangular cross-section.

[0015] In the above-mentioned steady flow water diverter valve, an installation channel connected to the buffer chamber is formed in the valve body, and the driving unit includes a valve cover threadedly connected in the installation channel, a valve stem abutting between the valve cover and the valve core; a sealing member is provided between the valve cover and the valve body.

[0016] In the above-mentioned steady flow water diverter valve, the valve core is provided with a first guide groove for accommodating the valve stem. The provision of the first guide groove can prevent the valve core from being stuck in the buffer cavity under the extrusion of the valve stem, and ensure the smoothness of the sliding fit between the valve core and the buffer cavity.

[0017] In the above-mentioned steady flow water diverter valve, the valve cover is connected to a circumferential drive located outside the valve body. In addition, the valve cover can also be rotated manually.

[0018] In the above-mentioned steady flow water diverter valve, the buffer chamber is connected to the first water outlet channel through a buffer channel arranged obliquely upward. The hot fluid entering the buffer chamber gradually flows into the buffer channel and finally enters the first water outlet channel, thus achieving further steady flow of the hot fluid.

[0019] The water distributor of the present invention comprises a water inlet pipe, the water inlet pipe is provided with a plurality of short joints, each short joint is connected to the water distribution pipe through the steady flow water distribution valve; the water inlet end of the steady flow water distribution valve is provided with a first connector for fixing the short joint, and the water outlet end of the steady flow water distribution valve is provided with a second connector for fixing the water distribution pipe.

[0020] The water distribution pipe of the water distributor of the present invention is separated from the water inlet pipe, and only a short joint for connecting the water distribution pipe is provided on the water inlet pipe. This not only facilitates the installation of the steady-flow water distribution valve, but also greatly reduces the overall volume of the water distributor, making it easy to repair or replace the water inlet pipe and the water distribution pipe separately.

[0021] In the above-mentioned water divider, the first connector comprises a first inner connecting sleeve and a first outer connecting sleeve arranged coaxially, the center of the first inner connecting sleeve is provided with a second water inlet channel; a flexible extrusion sleeve is provided on the outer wall of the first inner connecting sleeve, and a short joint installation space is formed between the flexible extrusion sleeve and the first inner connecting sleeve; the first outer connecting sleeve is threadedly connected to the valve body, and the valve body is used to squeeze the flexible extrusion sleeve to drive the short joint to fit tightly with the first inner connecting sleeve;

[0022] The second connecting head includes a second inner connecting sleeve and a second outer connecting sleeve fixedly arranged on the outer periphery of the second inner connecting sleeve, the center of the second inner connecting sleeve is provided with a second water outlet channel, and a water distribution pipe installation space is formed between the second outer connecting sleeve and the second inner connecting sleeve; the second inner connecting sleeve is threadedly connected to the valve body, and the second outer connecting sleeve is threadedly connected to the water distribution pipe.

[0023] Since the fluid flowing into the first water inlet channel from the water inlet pipe has a faster flow rate and a larger flow rate, a flexible extrusion sleeve needs to be provided in the first connector, and the flexible extrusion sleeve is circumferentially extruded by the first outer connecting sleeve and the valve body connected by thread, so as to ensure that the short connector is tightly connected to the steady-flow water diverter valve. However, the fluid flowing out of the first water outlet channel has a slower flow rate and a smaller flow rate, so the steady-flow water diverter valve and the water diverter pipe can be tightly connected by threading the second inner connecting sleeve and the valve body, and the second outer connecting sleeve and the water diverter pipe.

[0024] Compared with the prior art, the beneficial effects of this practical information are embodied in:

[0025] (1) The steady-flow water diverter valve of the present invention has a separate valve body, and the valve body and the valve core can achieve the expected sealing state. When in use, it is only necessary to connect the water inlet of the valve body to the water inlet pipe of the water diverter, and connect the water outlet of the valve body to the water diverter pipe of the water diverter. The entire installation and disassembly process is very simple and quick, and the sealing connection between the pipes is also more labor-saving.

[0026] (2) The steady-flow water diversion valve of the present invention is provided with a buffer chamber. The hot fluid entering from the water inlet pipe first flows slowly through the buffer chamber before entering the water outlet channel, ensuring that the hot fluid entering the water diversion pipe does not rush, thereby making the heat exchange efficiency of the hot fluid in each heating-requiring space higher.

[0027] (3) The water distribution pipe of the water distributor of the present invention is separated from the water inlet pipe, and only a short joint for connecting the water distribution pipe is provided on the water inlet pipe. This not only facilitates the installation of the flow-stabilizing water distribution valve, but also greatly reduces the overall volume of the water distributor, making it easier to repair or replace the water inlet pipe and the water distribution pipe separately.

[0034] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Example 1

[0036] like Figure 1 As shown, a water distributor in this embodiment includes a water inlet pipe 1, on which a plurality of short joints 11 are integrally formed, and each short joint 11 is connected to a water distribution pipe 3 through a steady-flow water distribution valve 2; and the return end of each water distribution pipe 3 is connected to a return pipe 4.

[0037] like Figure 4 Shown, combined Figure 2 and Figure 3 It can be seen that in this embodiment, the steady-flow water diverter valve 2 includes a valve body 21, which is T-shaped, and a first water inlet channel 21a with a water inlet 21b and a first water outlet channel 21c with a water outlet 21d are formed in the valve body 21, and the water inlet 21b and the water outlet 21d are on the same axis. The water inlet end of the valve body 21 is provided with a first connector 5 for fixing the short connector 11, and the water outlet end of the valve body 21 is provided with a second connector 6 for fixing the water diverter pipe 3.

[0038] At the same time, a buffer cavity 21e is formed in the valve body 21, which is connected to the first water inlet channel 21a and the first water outlet channel 21c. The axis of the buffer cavity 21e is perpendicular to the axis of the water inlet 21b and the water outlet 21d. A connecting hole 21f is formed between the buffer cavity 21e and the first water outlet channel 21c, and the connecting hole 21f is located below the first water inlet channel 21a. An installation channel 21g is also formed in the valve body 21, which is on the same axis as the buffer cavity 21e and the two are connected. A valve core assembly extending into the buffer cavity 21e is installed in the installation channel 21g; the valve core assembly is used to adjust the opening and closing state of the connecting hole 21f.

[0039] like Figure 4 As shown, the valve core assembly of this embodiment includes a valve core 22 slidably mounted in a buffer cavity 21e. The outer diameter of the valve core 22 itself is smaller than the inner diameter of the buffer cavity 21e, but the tail end of the valve core 22 is provided with an outer flange 22a that seals with the inner wall of the buffer cavity 21e; ​​the head end of the valve core 22 is provided with a valve head 23 that matches the communication hole 21f, and a limiting step 22b that abuts against the outer edge of the opening of the communication hole 21f is formed between the valve core 22 and the valve head 23. A return spring 24 is also sleeved on the outer periphery of the valve core 22, and the two ends of the return spring 24 abut against the outer flange 22a and the outer edge of the opening of the communication hole 21f, respectively.

[0040] At the tail end of the valve core 22, a driving unit for driving the valve head 23 away from or blocking the connecting hole 21f is also installed in the installation channel 21g, and the driving unit includes a valve cover 25 threadedly connected in the installation channel 21g, and a valve stem 26 is abutted between the valve cover 25 and the valve core 22. A first guide groove 22c for accommodating the valve stem 26 is provided in the valve core 22, and a second guide groove 25a for accommodating the valve stem 26 is provided on the valve cover 25. The first guide groove 22c and the second guide groove 25a can ensure that the valve stem 26 is always in a centered state.

[0041] like Figure 4 As shown, at one end of the valve cover 25 away from the valve stem 26, at least one first annular groove 25b is formed on the outer peripheral wall of the valve cover 25, and a first sealing ring 25c is installed in each first annular groove 25b. In this embodiment, the valve cover 25 can be rotated manually or connected to an external circumferential drive (not shown in the figure) to achieve electric control.

[0042] like Figure 4 As shown, in this embodiment, the valve head 23 is not in a complete cylindrical shape, but is formed with a notch 23a for connecting the buffer cavity 21e and the first water outlet channel 21c. The notch 23a has a triangular cross-section, and the opening of the notch 23a gradually becomes smaller from the end of the valve head 23 facing the connecting hole 21f to the end away from the connecting hole 21f. After the notch 23a is set, even if the valve head 23 is incorporated into the connecting hole 21f, the hot fluid in the buffer cavity 21e can still enter the first water outlet channel 21c from the notch 23a, and as the depth of the valve head 23 is increased, the flow of the hot fluid entering the first water outlet channel 21c becomes less and less until it is zero. Compared with the valve head 23 in a complete cylindrical shape, this valve head 23 structure is more conducive to regulating the fluid flow through the water diversion valve.

[0043] Depend on Figure 4 It can be seen that the connecting hole 21f is located at the middle and bottom end of the buffer cavity 21e, and the bottom end of the buffer cavity 21e is connected to the first water outlet channel 21c through the buffer channel 21h arranged obliquely upward. The hot fluid entering the buffer cavity 21e will gradually flow into the buffer channel 21h and finally enter the first water outlet channel 21c, thereby achieving further stabilization of the hot fluid flow.

[0044] like Figure 5 Shown, combined Figure 2 and Figure 3It can be seen that the first connector 5 of the present embodiment includes a first inner connecting sleeve 51 and a first outer connecting sleeve 52 which are coaxially arranged. The first inner connecting sleeve 51 and the first outer connecting sleeve 52 are separately arranged. A valve body installation space 53 is formed between the first inner connecting sleeve 51 and the first outer connecting sleeve 52. In the valve body installation space 53, the first outer connecting sleeve 52 is threadedly connected to the valve body 21. The water inlet 21b end of the valve body 21 is provided with a first outer thread section 21i. The inner wall of the first outer connecting sleeve 52 is provided with a first inner thread section 52a. A flexible extrusion sleeve 54 is provided on the outer wall of the first inner connecting sleeve 51. A short joint installation space 55 is formed between the flexible extrusion sleeve 54 and the first inner connecting sleeve 51. The center of the first inner connecting sleeve 51 is provided with a second water inlet channel 51a. On the side of the flexible extrusion sleeve 54 facing the short joint 11, the outer diameter of the first inner connection sleeve 51 is matched with the inner diameter of the short joint 11; and on the side of the flexible extrusion sleeve 54 facing the valve body 21, the outer diameter of the first inner connection sleeve 51 is matched with the inner diameter of the first water inlet channel 21a. At the same time, on the side of the flexible extrusion sleeve 54 facing the valve body 21, a second annular groove 51b is formed on the outer wall of the first inner connection sleeve 51, and a second sealing ring 56 is embedded in the second annular groove 51b. At the same time, a third sealing ring 57 is also sleeved on the first inner connection sleeve 51 to abut against the flexible extrusion sleeve 54, as shown in FIG. Figure 4 and Figure 5 As shown, the third sealing ring 57 and the inner wall of the first water inlet channel 21a are formed with wedge-shaped surfaces 57a and 21j that match each other.

[0045] like Figure 6 Shown, combined Figure 2 and Figure 3 It can be seen that in this embodiment, the second connector 6 includes a second inner connecting sleeve 61 threadedly connected to the valve body 21, the second inner connecting sleeve 61 has a second outer thread section 61a, and a second inner thread section 21k adapted thereto is formed on the inner wall of the first water outlet channel 21c of the valve body 21, and a second water outlet channel 61b is formed at the center of the second inner connecting sleeve 61. A second outer connecting sleeve 62 is also integrally formed on the outer periphery of the second inner connecting sleeve 61, and a water distribution pipe installation space 63 is formed between the second outer connecting sleeve 62 and the second inner connecting sleeve 61; the second outer connecting sleeve 62 is also threadedly connected to the water distribution pipe 3, and the second outer connecting sleeve 62 has a third inner thread section 62a, and the water distribution pipe 3 has a third outer thread section adapted thereto (not shown in the figure).

[0046] Depend on Figure 6It can be seen that in the water distribution pipe installation space 63, the second inner connecting sleeve 61 is also provided with a third annular groove 61c, and a fourth sealing ring 64 is embedded in the third annular groove 61c; at the same time, the second inner connecting sleeve 61 is also provided with a fifth sealing ring 65 that rests on the second outer connecting sleeve 62, and the fifth sealing ring 65 also has a wedge-shaped surface 65a that is compatible with the end of the water distribution pipe 3.

[0047] The working principle of the water divider in this embodiment is:

[0048] Before use, the water inlet end of each water distribution pipe 3 is fixedly connected to each short joint 11 of the water inlet pipe 1 using the steady flow water distribution valve 2, and then the water outlet end of each water distribution pipe 3 is fixed to each short joint 11 provided on the return pipe 4.

[0049] During use, when the temperature of the heating space where the water distribution pipe 3 is located is too high, the circumferential driver (not shown in the figure) on the corresponding steady-flow water distribution valve 2 is started to drive the valve core 22 downward, thereby reducing the flow of hot fluid entering the connecting hole 21f; otherwise, the valve core 22 is driven upward to increase the flow of hot fluid entering the connecting hole 21f.
