Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection structures, in particular to a pipeline connection structure for water supply without a tower. Background Art

[0002] Towerless water supply equipment, as the name suggests, actually uses a non-negative pressure air pressure tank to replace the traditional water tower or water tank. It is also called variable frequency non-negative pressure water supply equipment. The traditional water supply method is inseparable from the water tank. The water in the water tank is generally supplied by a tap water pipe. The pressurized water becomes zero after entering the water tank, resulting in a large amount of energy being wasted. It can replace the water tank and make full use of the pressure of the tap water network to directly or indirectly supply water, avoiding secondary waste of energy and secondary pollution, greatly saving infrastructure investment and shortening the construction period. The towerless water supply equipment consists of an intelligent variable frequency control cabinet, a flow stabilizer, a water pump unit, instruments, valves and pipelines, a base, etc., and is suitable for all water supply systems that require increased water pressure and constant flow.

[0003] The existing pipe connection structure for towerless water supply requires a large pressure increase, so the pressure on the connection is several times that of the usual connecting pipe, which is prone to the risk of loosening of the connection and waste of water resources; the existing pipe connection structure for towerless water supply has a poor fixing effect and is a single-layer fixed connection, which is prone to loosening and affects the water pressure of the water supply. Therefore, a pipe connection structure for towerless water supply is proposed to address the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by providing the connecting sleeve, the first air outlet, the first pressure relief valve and other components, when the pressure in the connecting pipe is too high, leakage will occur from the second air outlet and the second pressure relief valve at the connecting pipe, and the leaked pressure will continue to leak into the connecting sleeve. When the pressure in the connecting sleeve is too high, the excess pressure is discharged through the first air outlet and the first pressure relief valve at the top of the connecting sleeve to keep the pressure balance in the connecting pipe, thereby solving the problem that the existing pipeline connection structure for towerless water supply, due to the need for large-scale pressurization of towerless water supply itself, the pressure borne at the connection is several times that of the usual connecting pipe, and the risk of loosening of the connection is prone to occur, which wastes water resources;

[0020] A pipeline connection structure for towerless water supply, comprising a connecting sleeve 1, a limiting groove 9 is provided at one end of the connecting sleeve 1, a connecting pipe 8 is fixedly connected inside the limiting groove 9, a reinforcing layer 2 is fixedly connected inside the connecting pipe 8, an anti-corrosion layer 3 is fixedly connected inside the reinforcing layer 2, a fixing block 4 is fixedly connected inside the anti-corrosion layer 3, a filter screen 5 is fixedly connected inside the fixing block 4, a first thread 6 located at one end of the reinforcing layer 2 is provided on the inner side of the connecting pipe 8, a first rubber pad 7 is fixedly connected at one end of the connecting pipe 8, a limiting plate 11 is fixedly connected to the outer side of the connecting pipe 8, a spring 10 is fixedly connected to one side of the limiting plate 11, a second thread 14 located outside the connecting pipe 8 is provided on the inner side of the connecting sleeve 1, and a second rubber pad 15 located outside the second thread 14 is fixedly connected to the inner side of the connecting sleeve 1.

[0021] A first air outlet 12 is provided at the top of the connecting sleeve 1, and a first pressure relief valve 13 is fixedly connected to the outside of the first air outlet 12. A second air outlet 16 is provided at the top of the connecting pipe 8, and a second pressure relief valve 17 is fixedly connected to the top of the second air outlet 16. The end of the spring 10 away from the limiting plate 11 is fixedly connected to the connecting sleeve 1. The connecting sleeve 1 and the limiting groove 9 are a group, and there are two groups in total, which are symmetrically arranged at both ends of the connecting pipe 8. The fixed block 4 is in the shape of a circular ring and is arranged at the center of the anti-corrosion layer 3.

[0022] Working process: when it is necessary to use the pipe connection structure of tower-free water supply, firstly, the water pipe to be connected is inserted into the connecting sleeve 1, and the second thread 14 in the connecting sleeve 1 is spirally connected with the thread on the outside of the water pipe. As it is tightened continuously, the connected water pipe will enter the interior of the connecting pipe 8 and continue to be connected with the first thread 6 inside the connecting pipe 8. The first rubber pad 7 and the second rubber pad 15 can improve the overall sealing performance and prevent water leakage, thereby solving the problem that the existing pipe connection structure of tower-free water supply has a poor fixing effect, is a single-layer fixed connection, is prone to loosening, and affects the water pressure of the water supply. When the pressure in the connecting pipe 8 is too high, it will be discharged from the second air outlet 16 at the connecting pipe 8. If a leak occurs with the second pressure relief valve 17, the leaked pressure will continue to leak into the connecting sleeve 1. When the pressure in the connecting sleeve 1 is too high, the excess pressure will be discharged through the first air outlet 12 and the first pressure relief valve 13 at the top of the connecting sleeve 1 to keep the pressure balance in the connecting pipe 8. The impurities in the water can be filtered out by the set fixing block 4 and the filter screen 5 to prevent further blockage of the water pipe. The water pipe is a whole and it is more troublesome to clean it. The set limit plate 11 and spring 10 can play a certain shock-absorbing role to prevent the pipeline from shaking due to water pressure. The pressure relief valve is a prior art and is often used for pressure discharge. When the pressure reaches the critical value set by the pressure relief valve, the pressure relief valve will be pushed open to discharge the pressure.
