Description

Technical Field

[0001] This utility model relates to the field of PE pipe leakage detection technology, and in particular to a PE pipe leakage detection device. Background Technology

[0002] PE pipes are widely used in water supply, gas transmission, agricultural irrigation and other fields due to their excellent flexibility, corrosion resistance and easy installation.

[0003] The mechanism of the leakage detection device can be referenced from the utility model disclosed in authorization announcement number "CN219657113U" as "A PCP pipe joint leakage detection device". This device places the PCP pipe body between an exhaust block and a gas supply block. The operator then activates a dual-axis motor, along with a threaded rod, an internal threaded rod, and the installation of a fixed block, a moving block, and gas supply and exhaust blocks, to clamp the pipe to be tested. Simultaneously, the exhaust block and gas supply block securely seal the PCP pipe body. External gas is then introduced through a fan, passing through the gas supply block, pipe, exhaust block, and inner cavity, into a pressure gauge for pressure detection. Changes in the pressure gauge indicate whether there is leakage at the PCP pipe joint. This solution addresses the problem in existing PCP pipe joint leakage detection devices that, in order to reduce space requirements, can only move the device a short distance to secure the PCP pipe, thus limiting the detection range.

[0004] However, the sealing of the gas delivery block and the pipe interface in the above-mentioned device relies on physical contact and lacks an adaptive sealing design, which can easily lead to gas leakage due to uneven pipe surface or dimensional deviation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PE pipe leakage detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PE pipe leakage detection device includes a leakage detection device body, which includes two symmetrically arranged pressure blocks. The pressure blocks have a through-hole in the middle, and auxiliary components are provided on adjacent surfaces of the pressure blocks. The auxiliary components include a first fixing ring and a second fixing ring. The first fixing ring is fixedly installed on the outside of the pressure surface of the pressure block, and the second fixing ring is fixedly installed on the outside of the vent of the pressure block. A limit component is provided on the pressure surface of the pressure block between the first and second fixing rings, and an elastic sponge block is provided inside the reinforcing sealing component.

[0008] Furthermore, in a preferred configuration, the limiting component includes a magnetic ring, an auxiliary limiting ring one, and an auxiliary limiting ring two. The magnetic ring has a through hole in the middle located at the fixed ring two, and the auxiliary limiting ring two is inserted into one end of the magnetic ring and located outside the through hole. The auxiliary limiting ring one is inserted into the outside of one end of the magnetic ring.

[0009] Furthermore, in a preferred configuration, a plurality of limiting rods 1 are arranged in an equally spaced annular array on one side of the magnetic ring, and a plurality of limiting rods 2 are arranged in an equally spaced annular array on one side of the magnetic ring and on the outside of the through hole.

[0010] In addition, in a preferred configuration, slots are provided on one side of the auxiliary limiting ring one at the corresponding limiting rod one, and on one side of the auxiliary limiting ring two at the corresponding limiting rod two.

[0011] Furthermore, in a preferred configuration, the auxiliary limiting ring 1 has an external threaded portion on its exterior, and the fixing ring 1 has an internal threaded portion located at the external threaded portion, with the internal threaded portion and the external threaded portion being threadedly connected.

[0012] In addition, in a preferred configuration, both auxiliary limiting ring one and auxiliary limiting ring two are provided with magnetic material on the slot side that attracts the magnetic ring.

[0013] Furthermore, in a preferred configuration, a limiting ring is fixedly installed on the inner middle part of the auxiliary limiting ring one and the outer middle part of the auxiliary limiting ring two.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, an auxiliary component is set outside the air hole of the pressure block. The elastic sponge block in the auxiliary component fills the gaps caused by unevenness or dimensional deviation of the pipe surface, reduces gas leakage, and ensures the sealing of the PE pipe when the leakage detection device performs leakage detection. The elastic sponge block is detachable and can be disassembled and replaced after a period of use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A PE pipe leakage detection device includes a leakage detection device body 1. The leakage detection device body 1 includes two symmetrically arranged pressure blocks 11. A vent hole is opened through the middle of the pressure block 11, and auxiliary components 2 are provided on the adjacent surfaces of the pressure blocks 11. The auxiliary components 2 include a first fixing ring 21 and a second fixing ring 24. The first fixing ring 21 is fixedly installed on the outside of the pressure surface of the pressure block 11, and the second fixing ring 24 is fixedly installed on the outside of the vent hole of the pressure block 11. A limit component is provided on the pressure surface of the pressure block 11 between the first fixing ring 21 and the second fixing ring 24, and an elastic sponge block 23 is provided inside the reinforcing sealing component.

[0023] It is worth noting that the structure of the two symmetrically arranged pressure blocks 11 can be referenced from the exhaust block and gas supply block in the utility model "a PCP pipe interface leakage detection device" disclosed in the authorization announcement number "CN219657113U". The specific structure, connection method and working principle of the exhaust block, gas supply block and the leakage detection device body 1 are all existing technologies that have been disclosed on the market and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.

[0024] Furthermore, the limiting component includes a magnetic ring 25, an auxiliary limiting ring 1 22, and an auxiliary limiting ring 27. The magnetic ring 25 has a through hole in the middle located at the fixed ring 24, and the auxiliary limiting ring 27 is inserted into one end of the magnetic ring 25 and located outside the through hole. The auxiliary limiting ring 1 22 is inserted into the outside of one end of the magnetic ring 25.

[0025] Meanwhile, a plurality of limiting rods 251 are arranged in an equidistant ring array on one side of the magnetic ring 25, and a plurality of limiting rods 252 are arranged in an equidistant ring array on one side of the magnetic ring 25 and on the outside of the through hole.

[0026] Meanwhile, slots are provided on one side of the auxiliary limiting ring 22 at the corresponding limiting rod 251 and on one side of the auxiliary limiting ring 27 at the corresponding limiting rod 252.

[0027] Furthermore, the auxiliary limiting ring 22 has an external threaded portion on its exterior, and the fixing ring 21 has an internal threaded portion located at the external threaded portion, with the internal threaded portion and the external threaded portion being threadedly connected.

[0028] Furthermore, both auxiliary limiting ring 1 22 and auxiliary limiting ring 27 are provided with magnetic material on the side near the slot that attracts the magnetic ring 25.

[0029] Furthermore, a limit ring 26 is fixedly installed on the inner middle of the auxiliary limit ring 1 22 and the outer middle of the auxiliary limit ring 27.

[0030] In this embodiment, by setting an auxiliary component outside the air hole of the pressure block 11, the elastic sponge block 23 in the auxiliary component fills the gaps caused by unevenness or dimensional deviation of the pipe surface, reduces gas leakage, and ensures the sealing of the PE pipe when the leakage detection device performs leakage detection. Moreover, the elastic sponge block 23 is detachable and can be disassembled and replaced after a period of use.

[0031] When it is necessary to disassemble and replace the elastic sponge block 23, loosen the threads of the limiting component and remove it, and separate the magnetic ring 25 from the auxiliary limiting ring 1 22 and the auxiliary limiting ring 27, so that the elastic sponge block 23 can be separated and removed.

[0032] After replacement, first insert the replaced elastic sponge block 23 into the auxiliary limiting ring 22, and then connect the auxiliary limiting ring 22 to the magnetic ring 25. Then connect the auxiliary limiting ring 27 to the magnetic ring 25 to complete the placement of the elastic sponge block 23. Finally, screw the limiting component to the fixing ring 21 to complete the installation of the elastic sponge block 23.

[0033] Meanwhile, the auxiliary limiting ring 22 and the auxiliary limiting ring 27 are magnetically attached to the magnetic ring 25, further ensuring the installation of the elastic sponge block 23.

[0034] In this invention, by setting an auxiliary component outside the air hole of the pressure block 11, the elastic sponge block 23 in the auxiliary component fills the gaps caused by unevenness or dimensional deviation of the pipe surface, reduces gas leakage, and ensures the sealing performance of the leakage detection device when performing leakage detection on PE pipe. Moreover, the elastic sponge block 23 is detachable and can be disassembled and replaced after a period of use.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
