Description

Technical Field

[0001] The utility model relates to the technical field of pressure detection, in particular to a pressure detection structure for a water supply pipe. Background Art

[0002] As the name suggests, a water supply pipe is a pipe used to supply tap water. With the large-scale laying of tap water pipelines, in order to accurately know the pressure conditions in a water supply pipe in a certain place, a pressure detection structure is generally installed on the water supply pipe to detect the internal pressure. When a fault occurs, the pressure conditions in the water supply pipe can be clearly identified at the first time, and maintenance can be carried out based on this information. The existing pressure detection structure of the water supply pipe still has certain defects when used.

[0003] For example, a pressure detection device for a water supply network with the announcement number "CN209559388U" includes a tubular joint for connecting with a water supply pipe and for fixing on the water supply pipe, a pressure detection element for detecting the water pressure in the water supply pipe, and a sleeve for placing the pressure detection element in the water supply pipe, the sleeve is inserted into the tubular joint, the sleeve has a pressure measuring port for extending into the water supply pipe, and the pressure detection element is arranged in the sleeve near the pressure measuring port. The utility model provides a tubular joint on the water supply pipe, and a sleeve is installed in the tubular joint. The pressure measuring port of the sleeve is extended into the interior of the water supply pipe, so that the pressure detection element is built into the water supply pipe to detect the water pressure of the water supply pipe. Since the flowing water inside the water supply pipe will not freeze, the pressure detection element built into the water supply pipe can still accurately detect the water pressure inside the water supply pipe normally in the northern high-altitude cold areas or in the cold climate environment in winter.

[0004] The above technical solution detects the internal pressure of the water pipe through a pressure detection element. When the internal water pipe pressure is too high, it is impossible to release the pressure immediately. Under high pressure, it is easy to cause leakage or even collapse at the connection between the water pipes, and the safety is poor. Therefore, this solution proposes a pressure detection structure for a water supply pipe to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a pressure detection structure for a water supply pipe, aiming to solve the technical problem that when the pressure in the internal water pipe is too high, the pressure cannot be relieved immediately, and under high pressure, the connection between the water pipes is prone to leakage or even collapse, resulting in poor safety.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A pressure detection structure for a water supply pipe comprises a water pipe body and an end pipe embedded above the water pipe body, a closed pipe being fixedly provided at the upper end of the end pipe via a flange, a pressure detector being threadedly connected to the bearing surface of the closed pipe, and further comprising: a docking mechanism: the docking mechanism is embedded on the bearing surface of the closed pipe, a buffer mechanism: the buffer mechanism comprises a buffer box with an opening facing downwards arranged in the docking mechanism, a sealing frame being snap-connected in the buffer box, a partition plate being fixedly provided in the sealing frame, an elastic member for pushing the partition plate to reciprocate is fixedly provided on the upper end of the partition plate, and a guide member for limiting the position is fixedly provided on one side of the sealing frame.

[0008] In this solution, a buffer mechanism is provided. When the internal pressure of the water supply pipe is too high, the valve is opened, the pressure in the water pipe diffuses into the buffer box, and pushes the partition plate to move. Under the action of the elastic member, the partition plate moves back and forth until the internal pressure tends to be stable, so that the pressure can be released in time to improve safety.

[0009] In a preferred embodiment, the elastic member includes a first sleeve fixedly arranged on the upper end of the partition plate, a spring is fixedly arranged in the first sleeve, a second sleeve is fixedly arranged on the upper part of the buffer box, and the top end of the spring is fixedly arranged in the second sleeve.

[0010] The spring can move the partition plate upward along the buffer box when the partition plate is subjected to pressure shock, and gradually reset the partition plate when the pressure decreases, so that the partition plate maintains dynamic balance under the pressure shock.

[0011] In a preferred embodiment, the guide member includes a guide block fixedly arranged on one side of the sealing frame, the guide block is snap-connected in a guide groove, and the guide groove is provided on one side inside the buffer box.

[0012] The guide block and the guide groove can make the assembly of the partition plate and the sealing frame move up and down stably in the buffer box, and prevent the elastic potential energy of the spring from being too large, causing the assembly of the partition plate and the sealing frame to be pushed out of the buffer box.

[0013] In a preferred solution, the guide blocks and the guide grooves are symmetrically arranged in two groups about the central axis of the buffer box, and the height of the guide grooves is smaller than the inner depth of the buffer box.

[0015] By manually rotating the two sets of T-bars 90°, the T-plates will rotate accordingly. After the T-plates rotate 90°, their ends can be pulled out of the circular slots, so that the buffer box can be quickly removed and the internal components can be inspected. Similarly, during installation, the T-bars are also rotated. When the T-plates pass through the rectangular slots and enter the circular slots, the T-bars are released and the T-plates reset themselves and get stuck in the circular slots again, making installation more convenient.

[0016] As can be seen from the above, a pressure detection structure for a water supply pipe includes a water pipe body and an end pipe embedded above the water pipe body, a closed pipe is fixedly provided at the upper end of the end pipe through a flange, a pressure detector is threadedly connected to the bearing surface of the closed pipe, and also includes: a docking mechanism: the docking mechanism is embedded on the bearing surface of the closed pipe; a buffer mechanism: the buffer mechanism includes a buffer box with an opening facing downwards arranged in the docking mechanism, a sealing frame is snap-connected in the buffer box, a partition plate is fixedly provided in the sealing frame, an elastic member for pushing the partition plate to move back and forth is fixedly provided at the upper end of the partition plate, and a guide member for limiting is fixedly provided on one side of the sealing frame. The pressure detection structure for a water supply pipe provided by the utility model can achieve the technical effect of timely pressure relief when the pressure is too high without affecting the water supply of the water pipe body.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] The utility model discloses a pressure detection structure for a water supply pipe, which is mainly used when the pressure inside the water pipe is too high and the pressure cannot be relieved immediately. Under high pressure, the connection between the water pipes is prone to leakage or even collapse, resulting in poor safety.

[0026] Reference Figure 1 , Figure 2 and Figure 3 A pressure detection structure for a water supply pipe comprises a water pipe body 1 and an end pipe 2 embedded above the water pipe body 1, a closed pipe 3 is fixedly arranged on the upper end of the end pipe 2 through a flange, a pressure detector 4 is threadedly connected to the bearing surface of the closed pipe 3, and also comprises: a docking mechanism: the docking mechanism is embedded in the bearing surface of the closed pipe 3.

[0027] Buffer mechanism: The buffer mechanism includes a buffer box 17 with an opening facing downwards arranged in the docking mechanism, a sealing frame 18 is snap-connected in the buffer box 17, a partition plate 19 is fixedly arranged in the sealing frame 18, an elastic member for pushing the partition plate 19 to reciprocate is fixedly arranged on the upper end of the partition plate 19, and a guide member for limiting is fixedly arranged on one side of the sealing frame 18.

[0028] In this solution, the buffer box 17 can be quickly installed or removed through the docking mechanism, and maintenance is relatively convenient. When the internal pressure is too high, the pressure in the water pipe body 1 diffuses into the buffer box 17 and pushes the partition plate 19 to move upward along the buffer box 17, so that the pressure can be released in time.

[0029] Among them, the sum of the top-view cross-sectional areas of the sealing frame 18 and the partition plate 19 is equal to the top-view cross-sectional area inside the buffer box 17, which improves the sealing between the combination of the sealing frame 18 and the partition plate 19 and the inside of the buffer box 17, so that the pressure generated by the diffused pressure directly acts on the lower end of the sealing frame 18 and the partition plate 19.

[0030] Reference Figure 2 and Figure 4 In a preferred embodiment, the elastic member includes a first sleeve 20 fixedly disposed at the upper end of the partition plate 19, a spring 21 is fixedly disposed in the first sleeve 20, a second sleeve 22 is fixedly disposed on the upper part of the buffer box 17, and the top end of the spring 21 is fixedly disposed in the second sleeve 22.

[0031] Specifically, the spring 21 is arranged so that when the partition plate 19 is subjected to pressure, the spring 21 will be compressed and move upward along the buffer box 17. When the pressure is reduced, the partition plate 19 can be pushed to move downward and reset, so that the partition plate 19 is in a state of dynamic balance, thereby improving the pressure relief effect.

[0032] Reference Figure 4 In a preferred embodiment, the guide member includes a guide block 23 fixedly arranged on one side of the sealing frame 18, the guide block 23 is snap-connected in a guide groove 24, the guide groove 24 is opened on one side inside the buffer box 17, and the height of the guide groove 24 is less than the internal depth of the buffer box 17.

[0033] It should be noted that when the combination of the sealing frame 18 and the partition plate 19 moves up and down, the guide blocks 23 on both sides thereof follow the combination to move in the guide groove 24, limiting the combination to make the combination more stable when moving, and at the same time preventing the spring 21 from releasing its elastic potential energy and pushing the combination out of the buffer box 17.

[0034] Reference Figure 1 , Figure 3 and Figure 5In a preferred embodiment, the docking mechanism includes a valve 5 embedded in the bearing surface of the closed tube 3, a first round frame 6 is fixedly arranged on the top of the valve 5, a second round frame 9 is arranged on the upper end of the first round frame 6, a positioning pin 7 is fixedly arranged on the upper end of the first round frame 6, a positioning groove 8 is provided at the lower end of the second round frame 9, the positioning pin 7 is engaged and connected in the positioning groove 8, a rotating member for locking is provided in the second round frame 9, the rotating member includes a groove 10 provided at the upper end of the second round frame 9, and the bottom of the groove 10 is fixedly arranged on the upper end of the second round frame 9. A narrow groove 11 is provided on the surface, and a T-shaped rod 12 is connected through the narrow groove 11, and the end of the T-shaped rod 12 is rotatably connected in the groove 10, a torsion spring 13 is fixedly provided on the outer circumferential surface of the T-shaped rod 12, and the end of the torsion spring 13 is fixedly provided on the inner wall of the narrow groove 11, and a T-shaped plate 14 is fixedly provided at the end of the T-shaped rod 12, a rectangular groove 15 is provided on the upper end of the first circular frame 6, and a circular clamping groove 16 is provided on the inner bottom surface of the rectangular groove 15, and the end of the T-shaped plate 14 passes through the rectangular groove 15 and is clamped and connected in the circular clamping groove 16.

[0035] It is worth noting that when the buffer box 17 and its internal components need to be inspected and repaired, the two sets of T-rods 12 are manually rotated 90° counterclockwise. While the T-rods 12 drive the T-plate 14 to rotate, the torsion spring 13 is twisted. At this time, the T-plate 14 can be pulled out upward to remove the buffer box 17. During installation, the two sets of T-rods 12 are also rotated and moved downward along the locating pin 7. While the locating pin 7 is inserted into the locating groove 8, the T-rod 12 is released. Under the action of the torsion spring 13, the T-plate 14 resets itself and rests in the circular groove 16, and then the buffer box 17 is installed on the valve 5, which is convenient for disassembly and assembly of the buffer mechanism and for maintenance.

[0036] Working principle: First, install the closed tube 3 on the end tube 2 through the flange. After the closed tube 3 is connected to the end tube 2, its pressure detector 4 can detect the pressure in the water pipe body 1. When the pressure is too high, manually open the valve 5, and the pressure instantly diffuses to the buffer box 17 and acts on the partition plate 19. When the partition plate 19 is subjected to upward pressure, it will move upward along the buffer box 17 and compress the spring 21. Since the water flow in the water pipe body 1 does not stop, its pressure is also constantly changing. When the pressure decreases, under the action of the spring 21, the partition plate 19 moves downward. As the pressure changes, the partition plate 19 is also constantly moving up and down and is in a state of dynamic balance, so as to release the pressure in time to prevent the pressure from increasing continuously, resulting in direct action on the connection between the water pipe body 1 and the water pipe body 1, causing leakage.

[0037] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
