Description

Technical Field

[0001] This utility model relates to the field of water manifold technology, specifically to an intelligent high-flow water manifold. Background Technology

[0002] The manifold consists of a main distribution pipe and a main collection pipe. The main distribution pipe connects to the water supply pipe of the pipe network system. Its main function is to distribute hot water from the pipe network system to the rooms requiring underfloor heating through the underfloor heating pipes buried under the floor. As the hot water flows in the underfloor heating pipes, it transfers heat to the floor, and then radiates heat into the room through the floor. The water then returns to the main collection pipe, forming a loop.

[0003] To achieve automatic temperature control, intelligent manifolds typically use a shut-off valve core, which facilitates the up-and-down movement of the actuator to regulate flow. However, most existing shut-off valve seat structures are designed at the bottom of the main pipe of the manifold, where impurities or metal foreign objects easily accumulate. As the flow rate decreases, the up-and-down movement of the actuator can easily cause the sealing gasket to break or fall off, resulting in a failure to provide a seal. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides an intelligent high-flow-rate manifold. This manifold moves the valve seat that mates with the valve disc upwards, effectively reducing wear on the valve disc and valve stem, increasing their service life, and simultaneously increasing the diameter of the manifold main pipe to increase the flow rate.

[0005] The technical solution adopted to achieve the above-mentioned objectives of this utility model is as follows:

[0006] An intelligent high-flow-rate manifold includes a manifold main pipe and multiple shut-off valves. The bottom of the manifold main pipe has multiple equally spaced inlet and outlet ports. The manifold main pipe is connected to or isolated from each inlet and outlet port via shut-off valves. Each shut-off valve includes a valve stem and a valve disc. The valve stem is movably mounted on the top of the manifold main pipe, and the valve disc is mounted on the valve stem. The shut-off valve also includes a valve seat and a valve disc seal. The valve disc seal is mounted on the valve disc and fixedly sleeved on the lower end of the valve stem. The valve seat is tubular and passes through the corresponding inlet and outlet ports. The valve seat has a clearance fit with the corresponding inlet and outlet ports, and is detachably and sealingly mounted on the corresponding inlet and outlet ports. The top of the valve seat is not higher than the axis of the manifold main pipe. The top of the valve seat has an outer sealing ring, and the valve disc seal and valve disc can be sealed and connected to the outer sealing ring.

[0007] The valve seat is provided with an inner sealing ring at the top. The height of the inner sealing ring is less than the height of the outer sealing ring. A sealing groove is formed between the inner sealing ring and the outer sealing ring. When the valve disc seal and the valve disc are sealed to the outer sealing ring, the valve disc seal abuts against the inner sealing ring, and the valve disc seal deforms and fills the sealing groove.

[0008] The valve disc seal is made of EPDM rubber.

[0009] The valve disc is annular and is fixedly sleeved on the lower part of the valve stem. An annular limiting groove is provided on the side of the valve disc facing the lower end of the valve stem. The valve disc seal is annular and a limiting block is provided on the lower end of the valve stem. The upper end of the valve disc seal is located in the limiting groove, and the lower end of the valve disc seal abuts against the limiting block.

[0010] The outer diameter of the side of the valve disc seal that is connected to the valve disc is a fixed diameter, and the outer diameter of the side of the valve disc seal that is connected to the limiting block decreases from bottom to top.

[0011] The shut-off valve also includes a valve seat fixing component, which includes a locking nut and a retaining ring. Each inlet and outlet port is provided with an external thread. The retaining ring is sleeved on the lower part of the valve seat, and the locking nut is sleeved on the retaining ring. The locking nut is threadedly connected to the corresponding inlet and outlet port and presses the retaining ring tightly. The valve seat is fixed to the corresponding inlet and outlet port by the locking nut and the retaining ring.

[0012] The valve seat has an annular limiting ring at the bottom. The limiting ring is trumpet-shaped. The small end of the limiting ring is fixedly connected to the side wall of the valve seat and abuts against the corresponding inlet and outlet. One end of the retaining ring is located inside the limiting ring and abuts against the small end of the limiting ring.

[0013] A sealing ring is provided between the valve seat and the corresponding inlet / outlet.

[0014] Compared with the prior art, the beneficial effects and advantages of this utility model are as follows:

[0015] 1. In this manifold, the top of the valve seat that mates with the valve disc of the shut-off valve is moved up to a position slightly below the axis of the main manifold. The valve seat can block impurities or metal foreign objects, causing them to accumulate at the bottom of the main manifold. This effectively prevents impurities or metal foreign objects from wearing the valve disc and valve disc seals, thus improving the service life of the shut-off valve. At the same time, since the valve seat can be easily removed from the inlet and outlet, the impurities or metal foreign objects accumulated at the bottom of the main manifold can be cleaned off.

[0016] 2. In this manifold, the top of the valve seat that mates with the valve disc of the shut-off valve is moved up to a position slightly below the axis of the main manifold pipe. This can shorten the valve stem length, reduce torque, make the valve stem run more smoothly, and extend the service life of the valve stem.

[0017] 3. In this manifold, because the valve stem of the shut-off valve is shortened, the diameter of the main manifold pipe and the inlet and outlet can be increased, thereby increasing the flow rate.

[0018] 4. In this water distribution manifold, inner and outer sealing rings are installed on the valve seat of the shut-off valve, which can greatly increase the sealing effect between the valve disc and the valve seat. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] The structure of the intelligent high-flow-rate water manifold device provided in this embodiment is as follows: Figure 1-2 As shown, it includes a distribution main pipe 1 and multiple shut-off valves. The bottom of the distribution main pipe 1 is provided with multiple equally spaced inlet and outlet ports 2. The distribution main pipe 1 is connected to or isolated from each inlet and outlet port through shut-off valves.

[0025] like Figure 3 As shown, the gate valve includes a valve stem 3, a valve disc 4, a valve seat 6, a valve disc seal 5, and a valve seat fixing component. The valve stem 3 is movably mounted on the top of the manifold main pipe 1, and a limiting block 7 is provided on the lower end of the valve stem 3. The valve disc 4 is annular and is fixedly sleeved on the lower part of the valve stem 3. An annular limiting groove 8 is provided on the side of the valve disc 4 facing the lower end of the valve stem 3.

[0026] The valve disc seal 5 is annular in shape and made of EPDM rubber. One side of the valve disc seal 5 has a fixed outer diameter, while the outer diameter of the other side decreases sequentially. The valve disc seal 5 is fixedly sleeved on the lower end of the valve stem 3. The upper end of the valve disc seal 5 is located in the limiting groove 8, and the lower end of the valve disc seal 5 abuts against the limiting block 7. The axial direction of the valve disc seal 5 is limited by the valve disc 4 and the limiting block 7. The side of the valve disc seal 5 with a fixed outer diameter abuts against the valve disc 4, the side with a changing outer diameter abuts against the limiting block 7, and the end face with the smallest outer diameter of the valve disc seal 5 abuts against the limiting block 7.

[0027] The valve seat 6 is tubular and passes through the corresponding inlet / outlet 2. The valve seat 6 is clearance-fitted with the corresponding inlet / outlet 2, and a sealing ring 9 is provided between the valve seat 6 and the corresponding inlet / outlet 2. A ring-shaped limiting ring 15 is provided at the lower part of the valve seat 6. The limiting ring 15 is funnel-shaped. The small end of the limiting ring 15 is fixedly connected to the side wall of the valve seat 6, and the small end of the limiting ring 15 abuts against the corresponding inlet / outlet 2.

[0028] The valve seat fixing component includes a locking nut 10 and a retaining ring 11, with external threads on each inlet / outlet port 2. The retaining ring 11 is sleeved on the lower part of the valve seat 6, with one end of the retaining ring 11 located inside the limiting ring 15 and abutting against the small end of the limiting ring 15. The locking nut 10 is sleeved on the retaining ring 11, and the locking nut 10 is threadedly connected to the corresponding inlet / outlet port 2 and presses tightly against the retaining ring 11. The valve seat 6 is fixed to the corresponding inlet / outlet port 2 by the locking nut 10 and the retaining ring 11.

[0029] The top of valve seat 6 is slightly lower than the axis of the manifold main pipe 1. The top of valve seat 6 is provided with an outer sealing ring 12 and an inner sealing ring 13. The height of the inner sealing ring 13 is less than the height of the outer sealing ring 12, forming a sealing groove 14 between the inner sealing ring 13 and the outer sealing ring 12. When the valve disc seal 5 and valve disc 4 are sealed to the top of valve seat 6, the valve disc seal 5 is compressed and deformed, allowing it to seal with the outer sealing ring 12. The valve disc seal 5 abuts against the inner sealing ring 13, and fills the sealing groove 14. When the valve seat needs to be removed, the locking nut 10 can be unscrewed, followed by the removal of the retaining ring 11, and finally the valve seat 6 can be pulled out.

[0030] Moving the valve seat that mates with the valve disc of the gate valve upwards avoids wear on the valve disc seal 5 and valve disc 4 caused by friction with impurities or foreign metal objects. Simultaneously, it shortens the length of the valve stem 2, reducing torque and improving the service life of the valve disc seal 5, valve disc 4, and valve stem 2, thereby extending the service life of the gate valve and ultimately the manifold. Furthermore, the addition of an outer sealing ring 12, an inner sealing ring 13, and a sealing groove 14 on the top of the valve seat improves the sealing performance between the valve disc seal 5 and valve disc 4 and the valve seat 6.
