Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of design of supporting facilities for a live water system, in particular to a PPR pipe fitting for a live water system. Background Art
[0002] PPR material is the abbreviation of Polypropylene Random Copolymer, which is a plastic material commonly used in piping systems. It has the advantages of heat resistance, corrosion resistance, and high compressive strength, so it is widely used in the manufacture of water supply pipes, heating pipes, chemical pipes, etc. in households and industrial fields. PPR pipes have good durability and safety and are widely used in household and commercial running water systems.
[0003] In existing household water supply systems, most water-using facilities are directly connected to the main pipeline. When the water-using facilities stop using water, some stagnant water is likely to remain in the pipes connected to the main pipeline. Stagnant water can easily cause scale precipitation in the pipes and breed bacteria. Existing pipe fittings lack a live water system, that is, it cannot be guaranteed that water flows through the pipes at all times. The hygiene and anti-clogging capabilities of the pipes are low after long-term use. Utility Model Content
[0004] The purpose of the utility model is to provide a PPR pipe fitting for a live water system to solve the problems existing in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A PPR pipe fitting for a living water system comprises a supporting device, a connecting device is arranged at the rear of the supporting device, and an adjusting device is arranged at the front of the supporting device; the supporting device comprises a first connecting pipe, a plurality of limit blocks are evenly fixedly arranged on the middle circumference of the first connecting pipe, two first connecting heads are symmetrically fixedly arranged at both ends of the first connecting pipe, two diversion pipes are symmetrically fixedly arranged at the rear of the first connecting pipe, a switch valve is installed on the diversion pipe, and a second connecting head is fixedly arranged at the rear end of the diversion pipe; the connecting device comprises a second connecting pipe, two third connecting heads are symmetrically fixedly arranged in front of the second connecting pipe, and a mounting pipe is fixedly arranged at the bottom of the second connecting pipe; the adjusting device comprises an adjusting sleeve, a plurality of limit grooves are evenly arranged on the outer circumference of the adjusting sleeve, a support plate is fixedly arranged on one side of the adjusting sleeve, a spring is fixedly arranged on one side of the support plate, and an adjusting block is fixedly arranged at one end of the spring.
[0007] Furthermore: the cross section of the limit block is square.
[0008] Furthermore: the shunt pipe and the first connecting pipe are integrally formed.
[0009] Furthermore: the second connecting pipe is U-shaped.
[0010] Furthermore: the limiting block corresponds to the limiting groove one by one, and the adjusting sleeve is plug-in connected to the limiting block.
[0011] Furthermore: the adjusting block is connected to the adjusting sleeve by plugging and unplugging.
[0012] Furthermore: the adjusting block is connected to the spring bolt, and the supporting plate and the adjusting sleeve are integrally formed.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. When there is no water demand, the flow in the first connecting pipe is relatively large. At this time, when the water flows through the first connecting pipe, the regulating block moves to the left under the impact of the water flow, and the water flows through the regulating sleeve. The support plate support spring pushes the regulating block through elastic force, causing it to produce a certain resistance. Therefore, part of the water flows first into the right-hand diversion pipe, and then returns to the left-hand diversion pipe along the second connecting pipe to merge with the water flow passing through the regulating sleeve. During this process, all pipes inside the device have water flowing through them. When water is used at a certain point in the pipe, the water flow at the rear node becomes smaller. At this time, the water flow in the first connecting pipe at this point decreases. At this time, under the push of the spring, the regulating block almost blocks the regulating sleeve, and only a small amount of water can pass through the regulating sleeve, while the rest of the water flows into the second connecting pipe. At this time, if the water facilities installed on the corresponding installation pipe are opened, it can also ensure that more water can flow into the installation pipe. The design of the regulating block blocking the water flow when the flow is small can prevent the water output of a certain facility from being too small when water is used at the same time.
[0015] 2. When the water in the pipeline flows normally and the corresponding facilities of the installation pipe start to use water, the water flows outward at the installation pipe at a lower air pressure. Therefore, the water passing through the adjusting sleeve flows from the left diversion pipe through the second connecting pipe under the action of air pressure and enters the installation pipe. During this process, water also flows through the second connecting pipe, so that water always flows through the second connecting pipe at any time to prevent residual water from precipitating in the pipeline and generating scale. At the same time, the flowing water can kill bacteria such as Legionella to ensure the cleanliness of the inner wall of the pipeline. When closing the pipeline, the two switch valves need to be disconnected at the same time so that the installation pipe can be completely closed. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-Figure 4 A PPR pipe fitting for a live water system comprises a supporting device 1, a connecting device 2 is arranged at the rear of the supporting device 1, and an adjusting device 3 is arranged at the front of the supporting device 1.
[0026] In this embodiment: the support device 1 includes a first connecting pipe 101, a plurality of stoppers 102 are evenly fixedly arranged on the middle circumference of the first connecting pipe 101, two first connectors 103 are symmetrically fixedly arranged at both ends of the first connecting pipe 101, two diverter pipes 104 are symmetrically fixedly arranged behind the first connecting pipe 101, a switch valve 105 is installed on the diverter pipe 104, and a second connector 106 is fixedly arranged at the rear end of the diverter pipe 104, the stopper 102 has a square cross-section, and the diverter pipe 104 is integrally formed with the first connecting pipe 101. When installed, multiple first connecting pipes 101 are connected in series with the main water pipe through the first connector 103;
[0027] In this embodiment, the connecting device 2 includes a second connecting pipe 201, two third connecting heads 202 are symmetrically fixedly arranged in front of the second connecting pipe 201, and a mounting pipe 203 is fixedly arranged at the bottom of the second connecting pipe 201. The second connecting pipe 201 is U-shaped, and the third connecting head 202 on the second connecting pipe 201 is connected to the second connecting head 106 on the diversion pipe 104. The mounting pipe 203 is connected to water faucets, toilets, showers and other water-using equipment. When there is no water demand, when the water in the pipeline flows normally, the corresponding facilities of the mounting pipe 203 start to use water. The air pressure at 203 is low when the water flows outward, so the water passing through the regulating sleeve 301 flows from the left shunt pipe 104 through the second connecting pipe 201 and enters the installation pipe 203 under the action of air pressure. During this process, water also flows through the second connecting pipe 201, so that water always flows through the second connecting pipe 201 at any time, preventing residual water from precipitating in the pipe and generating scale. At the same time, the flowing water can kill bacteria such as Legionella, ensuring that the inner wall of the pipe is clean and hygienic. When closing the pipe, the two switch valves 105 need to be disconnected at the same time so that the installation pipe 203 can be completely closed;
[0028] In this embodiment, the regulating device 3 includes an regulating sleeve 301, a plurality of limiting grooves 302 are evenly arranged on the outer circumference of the regulating sleeve 301, a support plate 303 is fixedly arranged on one side of the regulating sleeve 301, a spring 304 is fixedly arranged on one side of the support plate 303, and an adjusting block 305 is fixedly arranged on one end of the spring 304, the limiting block 102 corresponds to the limiting groove 302 one by one, the regulating sleeve 301 is plugged and unplugged with the limiting block 102, the adjusting block 305 is plugged and unplugged with the regulating sleeve 301, the regulating block 305 is bolted to the spring 304, the support plate 303 and the regulating sleeve 301 are integrally formed, the regulating sleeve 301 is inserted into the middle of the first connecting pipe 101, the limiting block 102 is stuck in the limiting groove 302, and the installation of the regulating device 3 is completed. When there is no water demand, the flow in the first connecting pipe 101 is large. At this time, when the water flows through the first connecting pipe 101, the regulating block 305 moves to the left under the impact of the water flow, and the water flows through the regulating The spring 304 of the support plate 303 pushes the regulating block 305 through elastic force, causing a certain resistance. Therefore, part of the water flow first enters the shunt pipe 104 on the right, and then returns to the shunt pipe 104 on the left along the second connecting pipe 201, and merges with the water flow passing through the regulating sleeve 301. In this process, water flows through all pipes inside the device. When water is used at a certain point in the pipe, the water flow at the rear node becomes smaller. At this time, the water flow in the first connecting pipe 101 at this point decreases. At this time, under the push of the spring 304, the regulating block 305 almost blocks the regulating sleeve 301. Only a small amount of water can pass through the regulating sleeve 301, and the rest of the water flows into the second connecting pipe 201. At this time, if the water-using facilities installed on the corresponding installation pipe 203 are opened, it can also ensure that more water can flow into the installation pipe 203. The design of the regulating block 305 blocking the water flow when the flow rate is small can prevent the water output of a certain facility from being too small when water is used at the same time.
[0029] Working principle: During installation, multiple first connecting pipes 101 are connected in series with the main water pipe through the first connecting head 103, the adjusting sleeve 301 is inserted into the middle of the first connecting pipe 101, the limiting block 102 is inserted into the limiting groove 302, and the installation of the adjusting device 3 is completed. The third connecting head 202 on the second connecting pipe 201 is connected to the second connecting head 106 on the diversion pipe 104, and the installation pipe 203 is connected to the faucet, toilet, shower and other water-using equipment. When there is no water demand, the flow in the first connecting pipe 101 is large. At this time, the water flows through the first connecting pipe 101. During the process, the regulating block 305 moves to the left under the impact of the water flow, and the water flow passes through the regulating sleeve 301. The support plate 303 supports the spring 304 to push the regulating block 305 through the elastic force, causing it to produce a certain resistance. Therefore, part of the water flow first enters the right-hand diverter pipe 104, and then returns to the left-hand diverter pipe 104 along the second connecting pipe 201 to merge with the water flow passing through the regulating sleeve 301. In this process, all pipes inside the device have water flow passing through. When water is used at a certain point in the pipe, the water flow at the rear node becomes smaller. At this time, the water in the first connecting pipe 101 at that point The flow rate decreases. At this time, under the push of the spring 304, the regulating block 305 almost blocks the regulating sleeve 301. Only a small amount of water can pass through the regulating sleeve 301, and the rest of the water flows into the second connecting pipe 201. At this time, if the water-using facilities installed on the corresponding installation pipe 203 are turned on, more water can be guaranteed to flow into the installation pipe 203. The design of the regulating block 305 blocking the water flow when the flow rate is small prevents the water output of a certain facility from being too small when water is used at the same time. When the water in the pipeline flows normally, the corresponding facilities of the installation pipe 203 start to use water. The air pressure at 03 is lower when water flows outward. Therefore, the water passing through the adjusting sleeve 301 flows from the left side diversion pipe 104 through the second connecting pipe 201 and enters the installation pipe 203 under the action of air pressure. During this process, water also flows through the second connecting pipe 201, so that water always flows through the second connecting pipe 201 at any time, preventing residual water from precipitating in the pipe and generating scale. At the same time, the flowing water can kill bacteria such as Legionella, ensuring the cleanliness of the inner wall of the pipe. When closing the pipe, the two switch valves 105 need to be disconnected at the same time so that the installation pipe 203 can be completely closed.
