Description

Technical Field

[0001] The utility model relates to the technical field of water supply devices, in particular to an anti-loosening pre-adjusting water collector and a floor heating system. Background Art

[0002] At present, the stop valve core of the heating water collector is connected to the rod body, and the driver is connected to the stop valve core. This connection method can easily loosen the stop valve core when the driver is disassembled for maintenance. In addition, the driver will apply external force to the stop valve core when working. Long-term repeated force also increases the risk of the stop valve core loosening.

[0003] The current heating manifold controls the channel flow by adjusting the valve stem of the stop valve core through the driver. It can adjust the flow rate of the channel, but it cannot stabilize the hydraulic conditions of each branch channel according to the actual working conditions. In actual use, hydraulic imbalance of each branch may occur.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0034] The overall structure, working principle and technical effects of the anti-loosening pre-adjusting water collector 100 provided by the present invention are described in detail below through embodiments and in combination with the accompanying drawings.

[0035] Example

[0036] See also Figure 1 、 Figure 2 、 Figure 6 and Figure 7 The present embodiment provides an anti-loosening pre-adjusting water collector 100, comprising a rod body 110, a stop-type valve core 120, a driver 130, an adjusting spring 140 and an adjusting cover 150. The rod body 110 is fixedly provided with a plurality of branches 111 and a plurality of mounting portions 112 on both sides along the axis of the rod body 110. The branches 111 and the mounting portions 112 correspond to each other one by one. The stop-type valve core 120 is arranged in the mounting portion 112 for opening and closing the branches 111. The stop-type valve core 120 and the mounting portion 112 are fixedly provided with a plurality of branches 111 and a plurality of mounting portions 112 on both sides along the axis of the rod body 110. An annular cavity 113 is formed between the mounting portion 112 and the mounting portion 112 for mounting an adjustment spring 140. An adjustment cover 150 is sleeved over the stop valve core 120 and abuts against the adjustment spring 140. The inner side surface of the mounting portion 112 is provided with an internal thread 1121, and the outer side surface of the mounting portion 112 is provided with an external thread 1122. The adjustment cover 150 is engaged with the internal thread 1121. Specifically, the adjustment cover 150 is provided with an adjustment thread 153, which is threadably connected to the internal thread 1121. The driver 130 is provided with a union nut 131, which is engaged with the external thread 1122. The driver 130 contacts the stop valve core 120 and drives the valve stem 122 of the stop valve core 120 to move up and down.

[0037] In this embodiment, the installation of the stop valve core 120 is achieved by utilizing the mounting portion 112, and the union nut 131 is directly connected to the mounting portion 112, that is, the driver 130 is directly connected to the rod body 110. At this time, except for the valve stem 122, the stop valve core 120 does not contact the driver 130, which can effectively prevent the driver 130 from loosening the stop valve core 120 during disassembly and maintenance. Moreover, only the valve stem 122 of the stop valve core 120 contacts the driver 130. At this time, the driver 130 only applies a force to the valve stem 122 of the stop valve core 120 during operation, and does not apply any extra external force to the stop valve core 120 as a whole, thereby further reducing the risk of the stop valve core 120 loosening. In this embodiment, by providing an adjusting cover 150 and an adjusting spring 140, the installation position of the stop valve core 120 can be adjusted stably and reliably. In addition, by compressing the adjusting spring 140 through the adjusting cover 150, the channel openings of each branch 111 are pre-adjusted, which can stabilize the hydraulic pressure of each branch 111 and avoid imbalance in the water pressure of each branch 111.

[0038] Specifically, see Figure 3 and Figure 4 In this embodiment, the outer side surface of the mounting portion 112 is provided with a positioning surface 1123 and a connecting portion 1124. An external thread 1122 is provided on the connecting portion 1124. The end of the driver 130 abuts against the positioning surface 1123, and the union nut 131 is threadedly connected to the connecting portion 1124. The positioning surface 1123 is used to locate the installation position of the driver 130. The union nut 131 is then threadedly connected to the connecting portion 1124, making it easy to install the driver 130 on the mounting portion 112 and to remove it.

[0039] Furthermore, in this embodiment, a scale 1125 is provided on the circumference of the mounting portion 112, and an indicator arrow 151 is provided on the adjustment cover 150 for displaying the adjustment degree of the adjustment cover 150. An external hexagonal corner 152 is provided on the top of the adjustment cover 150. By rotating the external hexagonal corner 152 of the adjustment cover 150, the adjustment cover 150 can be rotated. Because the adjustment cover 150 is mated with the internal thread 1121 on the mounting portion 112, the installation depth of the adjustment cover 150 can be adjusted during rotation. By rotating the adjustment cover 150 upward or downward, the stop valve core 120 and the adjustment spring 140 are squeezed, thereby adjusting the position of the stop valve core 120 within the mounting portion 112, thereby adjusting the channel openings of each branch 111 and stabilizing the hydraulic pressure of each branch 111. The scale 1125 and indicator arrow 151 provide a convenient indication of the rotation angle and adjustment depth during rotation, making it easier for the operator to clearly understand the adjustment status.

[0040] In this embodiment, a first inner hole 1126 and a second inner hole 1127 are sequentially arranged inside the mounting part 112 along the direction from the mounting part 112 to the rod body 110. The diameter of the second inner hole 1127 is smaller than that of the first inner hole 1126, so that a stepped shape is formed inside the mounting part 112, which is convenient for installing the stop valve core 120.

[0041] Please refer to Figure 5 , in which the stop valve core 120 includes a valve body 121, a valve stem 122, a valve cover 123 and a return spring 124. The return spring 124 is sleeved on the valve stem 122. The valve stem 122 passes through the valve body 121 and both ends extend out of the valve body 121 respectively. The valve cover 123 passes through the valve stem 122 and is arranged on the valve body 121. A flange 1211 is arranged in the middle of the valve body 121. One end of the valve stem 122 contacts the driver 130, and the other end of the valve stem 122 is connected to the branch 111.

[0042] The valve body 121 is provided with a first cylinder 1212 and a second cylinder 1213. The flange 1211 is arranged between the first cylinder 1212 and the second cylinder 1213. When the valve body 121 cooperates with the mounting part 112, the second cylinder 1213 cooperates with the second inner hole 1127 and extends out of the second inner hole 1127. Since the diameter of the first inner hole 1126 is larger than that of the second inner hole 1127, an annular cavity 113 is formed between the outer side surface of the second cylinder 1213 extending out of the second inner hole 1127, the inner side surface of the first inner hole 1126 and the flange 1211. The adjusting spring 140 is installed in the annular cavity 113. The adjusting cover 150 abuts against one side of the flange 1211, and the adjusting spring 140 abuts against the other side of the flange 1211. By rotating the adjusting cover 150, the flange 1211 can be squeezed, and then the adjusting spring 140 can be squeezed, so that the valve body 121 can move up and down within a certain range driven by the adjusting cover 150, thereby adjusting the installation position of the stop valve core 120. In this embodiment, the spring force of the adjusting spring 140 is greater than the spring force of the return spring 124, so as to ensure that the main body part of the stop valve core 120 is in a constant position when the driver 130 works.

[0043] In order to maintain the sealing performance when the valve body 121 moves up and down in the mounting part 112, in this embodiment, a first groove 1214 is arranged on the outer side surface of the second cylinder 1213, and a first sealing ring 1215 is arranged in the first groove 1214. At the same time, in order to maintain good sealing performance when the valve core moves up and down in the valve body 121 based on the left and right of the driving part, in this embodiment, a second groove 1216 is arranged on the inner side surface of the second cylinder 1213, and a second sealing ring 1217 is arranged in the second groove 1216, and the valve core abuts against the second sealing ring 1217.

[0044] A gasket 1221 is also provided at one end of the valve stem 122 close to the branch 111. The provision of the gasket 1221 can further define the movement direction of the valve stem 122, avoiding the situation of the valve stem 122 shifting or shaking. At the same time, the gasket 1221 can also slow down the acting force of the valve stem 122 on the branch 111, ensuring that the opening condition of the branch 111 is milder.

[0045] Please refer to Figures 1 - 7 , the working principle of the anti-loosening pre-adjustable water collector 100 provided in this embodiment is as follows: The adjusting spring 140 is sleeved on the valve body 121 of the stop-type valve core 120, and then the stop-type valve core 120 is installed in the installation part 112. When the valve body 121 cooperates with the installation part 112, the second cylinder 1213 cooperates with the second inner hole 1127 and extends out of the second inner hole 1127. Since the diameter of the first inner hole 1126 is larger than that of the second inner hole 1127, an annular cavity 113 is formed between the outer side surface of the second cylinder 1213 extending out of the second inner hole 1127, the inner side surface of the first inner hole 1126, and the flange 1211. The adjusting spring 140 is installed in the annular cavity 113, and the adjusting spring 140 abuts against the flange 1211. Subsequently, the adjusting cover 150 is installed. The adjusting cover 150 is threadedly connected to the internal thread 1121 of the installation part 112, and the bottom of the adjusting cover 150 abuts against one side of the flange 1211. Subsequently, the end of the driver 130 is abutted against the positioning surface 1123, and the union nut 131 is threadedly connected to the connecting part 1124. The installation position of the driver 130 is positioned through the positioning surface 1123. Subsequently, by threadedly connecting the union nut 131 with the connecting part 1124, it is convenient to install the driver 130 on the installation part 112. The valve stem 122 of the stop-type valve core 120 extends out of the adjusting cover 150 and contacts the driver 130. The driver 130 can drive the valve stem 122 to move up and down, thereby starting the branch 111 and adjusting the flow rate of the branch 111.

[0046] In addition, the present utility model also provides a floor heating system, which includes the above anti-loosening pre-adjustable water collector 100.

[0047] In summary, the anti-loosening pre-adjustable water collector 100 provided by the present utility model uses the installation part 112 to directly connect the driver 130 to the installation part 112 on the rod body 110, without connecting to the stop valve core 120, and only contacts the valve stem 122 of the stop valve core 120 and drives the valve stem 122 to move up and down. By changing the connection position of the driver 130, it effectively avoids the driver 130 from driving the stop valve core 120 to become loose during disassembly and maintenance. Moreover, only the valve stem 122 of the stop valve core 120 contacts the driver 130. At this time, when the driver 130 is working, it only applies a force to the valve stem 122 of the stop valve core 120, and does not apply an extra external force to the whole stop valve core 120, thereby further reducing the risk of the stop valve core 120 becoming loose. In this embodiment, by setting the adjusting cover 150 and the adjusting spring 140, the installation position of the stop valve core 120 can be adjusted, which is stable and reliable. And by compressing the adjusting spring 140 with the adjusting cover 150, the channel openings of each branch 111 can be pre-adjusted to balance the water power of each branch 111 and avoid the water pressure imbalance of each branch 111.

[0048] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
