Description

Technical Field

[0001] This utility model belongs to the field of water distributor design technology, and specifically relates to a water distributor pipe body with a limiting function. Background Technology

[0002] Water distributors and collectors are devices used in water systems to connect the supply and return water of various heating pipes. They are classified as water distributors and water collectors based on the inlet and outlet water flow. Therefore, they are called water distributors or water collectors / distributors, and are commonly known as water distributors.

[0003] Currently, Chinese patent publication number CN2647925, published on October 13, 2004, discloses a novel adjustable water distributor, including a fixed bracket. The water distributor's pipeline within the fixed bracket is divided into two parts: an upper water supply line for water distribution control, where a straight pipe connector is integrated with a manual flow regulating valve. The flow rate is adjusted by rotating the flow regulating rod and the contact gap between the straight pipe connector, thus providing both the flexibility of the straight pipe connector for water distribution and the regulation function of a single circuit; and a lower water supply line for water collection control, connecting a straight pipe connector and a flow meter. The straight pipe connector and the flow meter regulating rod are also integrated. The straight pipe connector is used for return water, and the flow meter can monitor the flow rate of a single circuit to adjust the flow rate of the pipeline in a timely manner.

[0004] The system consists of multiple pipe joints connected to multiple heating elements, each corresponding to a different room. Flow control valves regulate the flow rate of each pipe joint, thereby controlling the flow rate of the heating elements in each room. Rotating the valve handle changes the opening, directly adjusting the water flow rate of the corresponding heating branch, thus precisely controlling the temperature of different rooms or areas. However, when rotating any flow control valve, it is easy to accidentally touch an adjacent flow control valve, causing it to deflect incorrectly and ultimately causing considerable inconvenience to the user. Utility Model Content

[0005] The purpose of this utility model is to provide a water distributor pipe body with a limiting function, which can limit the position of the knob after the flow regulating valve is adjusted.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water distributor pipe body with a limiting function, including a water inlet pipe of the water distributor, multiple flow regulating valves located on the upper side of the water inlet pipe, and multiple pipe joints located on the lower side of the water inlet pipe and corresponding to the multiple flow regulating valves respectively. The flow regulating valve includes a valve stem, an adjusting head located at the lower end of the valve stem and at the upper end of the pipe joint, and a knob located at the upper end of the valve stem. A column with a rectangular cross-section is integrally provided at the upper end of the valve stem. A rectangular groove is provided at the center of the knob for the column to be inserted and to cooperate with the cross-section of the column. A return spring is provided in the rectangular groove, with its upper end connected to the inner wall of the rectangular groove and its lower end connected to the upper end face of the column. A ring platform with corresponding flow scale is provided on the periphery of the lower end of the knob. A pointer indicating the flow scale is fixed on the upper outer wall of the water inlet pipe. A rotating platform is provided on the periphery of the middle part of the knob. Multiple positioning tooth grooves for the upper end of the pointer to be inserted are provided on the periphery of the lower part of the rotating platform.

[0007] A further feature of this invention is that: a sleeve for the valve stem to pass through is provided on the water inlet pipe; a positioning ring is fixed on both ends of the valve stem and at both ends of the sleeve; an external threaded post is provided at the upper end of the adjusting head; an internal threaded sleeve for threaded connection of the external threaded post is fixed inside the water inlet pipe; a cross groove extending vertically downward is provided on the upper end face of the external threaded post; and a cross post for embedding in the cross groove is provided on the lower end face of the valve stem.

[0008] A further feature of this invention is that a sealing ring is embedded in the circumferential side of the upper end of the rod sleeve.

[0009] A further feature of this invention is that the rotating platform is provided with anti-slip stripes on its periphery.

[0010] A further feature of this invention is that a filter screen is provided inside the lower end of the pipe joint.

[0011] A further feature of this invention is that the filter screen is a cone shape with the opening facing upwards, an external threaded sleeve is fixed to the periphery of the filter screen, and an internal threaded surface is provided at the lower end of the pipe joint for the external threaded sleeve to be threadedly connected.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. When adjusting the flow control valve, first lift the knob upwards so that the upper end of the pointer disengages from the positioning tooth groove and the return spring is stretched. Then, the upper end of the pointer will indicate the flow scale on the ring platform. Rotating the knob will adjust the flow control valve. After the flow control valve is adjusted, release the knob. Under the elastic restoring force of the return spring, the knob will move downwards, and the upper end of the pointer will re-enter the positioning tooth groove. At this time, the position of the knob after rotation is positioned by the connection between the pointer and the positioning tooth groove, thus limiting the position of the knob after the flow control valve is adjusted.

[0014] 2. When the knob is turned, it drives the valve stem to rotate via the column. Since the valve stem is connected to the rod sleeve via the positioning ring, the positioning ring can position the valve stem vertically. As the valve stem rotates, it drives the external thread column to rotate within the internal thread sleeve via the cross column and cross groove. Subsequently, the external thread column can move up and down along the internal thread sleeve for adjustment, which in turn drives the adjusting head to move up and down for adjustment, thereby changing the flow rate entering the pipe joint.

[0015] 3. By using the sealing ring embedded in the circumference of the upper end of the sleeve, the sealing ring can seal the gaps inside the sleeve, reducing the possibility of liquid leakage.

[0016] 4. The anti-slip stripes on the periphery of the rotary table provide a non-slip effect, which helps the operator to rotate the knobs stably.

[0017] 5. When the liquid in the inlet pipe enters the pipe joint, the liquid can be filtered by the filter screen inside the pipe joint to prevent impurities from entering the underfloor heating pipe and causing blockage inside the underfloor heating pipe. When the filter screen becomes clogged, simply open the pipe joint to clean the filter screen.

[0018] 6. Because the filter screen is a cone shape with the opening facing upwards, impurities can be collected in the middle of the filter screen, reducing the possibility of clogging. At the same time, the filter screen is connected to the inner thread surface by the external thread, so that the filter screen can be detached in the pipe joint, making it convenient to disassemble and clean the filter screen.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] A water distributor pipe body with a limiting function, as shown in the reference. Figure 1 , Figure 2 The manifold with limiting function includes a manifold inlet pipe 1, multiple flow regulating valves 2, and multiple pipe joints 3. The multiple flow regulating valves 2 are installed on the upper side of the inlet pipe 1, while the multiple pipe joints 3 are fixedly connected to the lower side of the inlet pipe 1 and correspond to the multiple flow regulating valves 2 respectively. The underfloor heating pipe can be connected through the pipe joints 3. At the same time, a filter screen 4 is also provided in the lower end of the pipe joint 3. The filter screen 4 is a cone shape with the opening facing upward. The filter screen 4 has an external threaded sleeve 41 welded on its periphery, and the lower end of the pipe joint 3 has an internal threaded surface 31 for the external threaded sleeve 41 to be threadedly connected.

[0027] Reference Figure 1 , Figure 2 , Figure 3The flow regulating valve 2 includes a valve stem 21, an adjusting head 22 located at the lower end of the valve stem 21 and the upper end of the pipe connector 3, and a knob 23 located at the upper end of the valve stem 21. The upper end of the valve stem 21 has an integrally formed rectangular column 211, and the center of the knob 23 has a rectangular groove 231 for the column 211 to be inserted into and to fit the cross-section of the column 211. A return spring 232 is installed within the rectangular groove 231, with its upper end connected to the inner wall of the groove and its lower end connected to the upper surface of the column 211. A ring platform 233 is integrally provided on the lower periphery of the knob 23, and the outer wall of the ring platform 233 is engraved with corresponding flow scales; a pointer 11 corresponding to the position of each flow regulating valve 2 and used to indicate the flow scale is also welded and fixed on the upper outer wall of the water inlet pipe 1; a rotating platform 234 is integrally provided on the middle periphery of the knob 23, and multiple positioning grooves 2341 for the upper end of the pointer 11 to be inserted are opened on the lower periphery of the rotating platform 234; and anti-slip stripes 2342 are integrally provided on the periphery of the rotating platform 234.

[0028] Reference Figure 2 , Figure 4 The inlet pipe 1 is integrally provided with a sleeve 12 for the valve stem 21 to pass through. Positioning rings 212 are fixed on both ends of the valve stem 21 and at the two ends of the sleeve 12. A sealing ring 121 is embedded in the circumference of the upper end of the sleeve 12. The upper end of the adjusting head 22 is welded with an external threaded post 221. An internal threaded sleeve 13 for threaded connection of the external threaded post 221 is welded and fixed inside the inlet pipe 1. At the same time, a cross groove 2211 extending vertically downward is opened in the upper end face of the external threaded post 221. A cross post 213 for embedding in the cross groove 2211 is welded at the lower end face of the valve stem 21.

[0029] Principle: When the flow regulating valve 2 needs to be adjusted, first lift the knob 23 upwards, so that the upper end of the pointer 11 disengages from the positioning groove 2341 and the return spring 232 is stretched. Then the upper end of the pointer 11 can indicate the flow scale on the ring platform 233. After rotating the knob 23, the flow regulating valve 2 can be adjusted. After the flow regulating valve 2 is adjusted, release the knob 23. Under the elastic restoring force of the return spring 232, the knob 23 can move downwards. Then the upper end of the pointer 11 can be embedded again in the positioning groove 2341. At this time, the position of the knob 23 after rotation is positioned by the connection between the pointer 11 and the positioning groove 2341. Finally, the position of the knob 23 after the flow regulating valve 2 is adjusted can be limited.

[0030] When knob 23 is turned, it drives valve stem 21 to rotate via column 211. Since valve stem 21 is connected to rod sleeve 12 via positioning ring 212, positioning ring 212 can position valve stem 21 vertically. As valve stem 21 rotates, it drives external thread column 221 to rotate within internal thread sleeve 13 via cross column 213 and cross groove 2211. Subsequently, external thread column 221 can move up and down along internal thread sleeve 13 for adjustment, which in turn drives adjustment head 22 to move up and down for adjustment, thereby changing the flow rate entering pipe joint 3.
