Safety device for tap water delivery pipeline

The present invention relates to a safety design, and in particular to a safety device for a water supply pipeline.

Investigate that tap water has been regarded as a universally available resource by the public. To meet the needs of people's livelihood and industrial water, the water company not only implements diversified water source development and measures to reduce water leakage rate, but also provides sufficient water to build a modern treatment. Equipment, intensified water quality monitoring and detection, and reduction of water source pollution to ensure the quality of water sources. It is also connected to the water supply plant and the demand side by means of a wide-scale tap water supply pipeline, thereby realizing the demand for people's livelihood and industrial water.

In view of the large number of tap water pipelines, and some tap water pipelines are located at a certain distance from the water supply plant, the water company is more suitable for the water supply pipelines in order to achieve better water supply. The pressurizing station can repressurize the water transported away from the water supply plant, thereby improving the lack of water volume due to insufficient water supply pressure of the user at the end of the tap water conveying pipeline, and even causing the water to be unable to reach the demand side. As a result of the user's lack of water and other problems, the setting of these pressurized stations does have a certain effect.

However, although the water company has a large number of pressurized stations, it can solve the problems of too little water pressure or even water supply. However, after actual use, it is found that, except for a large number of pressurizing stations, the water pressure in the tap water conveying pipes becomes large. In the case of long-term maintenance under high pressure, the tap water conveying pipeline will burst when it cannot withstand it. Furthermore, if the tapping of the tap water conveying pipeline is buried in the ground, it will be prolonged and repaired. Time, which greatly affects the water use of households, needs to be improved.

Therefore, the object of the present invention is to provide a safety device for a tap water conveying pipe which has the function of adjusting the water pressure to prevent the pipe from rupturing and thereby prolonging the service life of the tap water conveying pipe.

Therefore, the safety device of the new tap water conveying pipeline comprises a water inlet pipe connected to the tap water conveying pipeline and allowing water to flow in, a pressure releasing group connected to the water inlet pipeline, and a pressure releasing group connected thereto. a water outlet pipe; wherein the pressure relief group has a body internally formed with a conduction passage and connected to the water inlet pipe, a control valve disposed in the conduction passage, and an elastic member capable of topping the control valve, The elastic member has an adjustable top thrust top control valve, and the other end of the conductive passage is connected to the water outlet pipe so that the water pressure in the tap water conveying pipe is greater than the top thrust of the elastic member. The water pressure will open the control valve so that part of the water flow can pass through the conduction channel and be discharged through the water outlet pipe, thereby adjusting the excessive pressure of the tap water delivery pipe, which can effectively prevent the tap water pipe. The road is broken, and the tap water conveying pipeline is prevented from being fatigued due to long-term excessive water pressure, and the service life of the tap water conveying pipeline can be greatly extended.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

Referring to Figures 1 and 2, in a first preferred embodiment of the safety device 3 of the present type of tap water delivery line 4, the safety device 3 is disposed on the tap water delivery line 4, and the tap water delivery line 4 is There is a conveying passage 41 formed inside and available for water to flow, and the safety device 3 includes a water inlet pipe 31 communicating with the conveying passage 41 of the tap water conveying pipe 4 and allowing water to flow therein, and is connected to the water inlet pipe 31. The pressure release group 32 and a water outlet pipe 33 connected to the pressure release group 32.

The pressure relief group 32 has a body 322 having a conductive passage 321 formed therein, and the two ends of the body 322 are respectively connected to the water inlet pipe 31 and the water outlet pipe 33, and are disposed in the conduction channel 321 The control valve 323, and an elastic member 324 of the control valve 323, and the elastic member 324 has a set top thrust top control valve 323, and the safety device 3 can be disposed on any tap water as needed. The delivery line 4 is connected to the delivery channel 41 of the tap water delivery line 4 by the water inlet line 31, so that the water flow in the delivery channel 41 can flow into the pressure release group 32 via the water inlet line 31, and further The elastic member 324 can be mounted on the control valve 323 by setting the top thrust of the elastic member 324, and the safety device 3 can be disposed at a place where the water flow can be easily discharged, such as a storage tank, a pond, or a trench. In the present embodiment, the safety device 3 is described by taking the tap water delivery line 4 adjacent to the trench as an example, as shown in FIG. 2 .

Referring to FIG. 3, in the normal use of the safety device 3 of the present water supply pipeline 4, since the water flow pressure in the conveying passage 41 is not greater than the top thrust set by the elastic member 324, the control valve 323 is subjected to the elasticity. The top thrust of the piece 324 is pushed and closed tightly. Therefore, the water flow in the tap water delivery line 4 does not flow out through the pressure release group 32 of the safety device 3, and the water pressure in the tap water delivery line 4 is also Not affected by the safety device 3.

Referring to FIG. 4, when the water flow pressure of the delivery passage 41 flowing into the pressure relief group 32 via the water inlet conduit 31 is greater than the top thrust force set by the elastic member 324, the flow of water flowing in the delivery passage 41 will open the control. The valve 323 is configured such that a part of the water flow can flow through the gap opened by the control valve 323 through the conduction passage 321 in the body 322 and is discharged into the groove through the water outlet pipe 33, and the water pressure inside the conveying passage 41 is received. When the pressure release group 32 is gradually released and is less than the top thrust of the elastic member 324, the elastic member 324 returns to the state before the opening, so that the control valve 323 is again closely closed by the elastic member 324, such as As shown in FIG. 3, the pressure applied to the conveying passage 41 of the tap water conveying line 4 is completed, which not only effectively prevents the tap water conveying line 4 from being broken, but also prevents the tap water conveying line 4 from being overburdened for a long time. The phenomenon of fatigue caused by water pressure can greatly extend the service life of the tap water delivery line 4.

In summary, the safety device of the present invention for the tap water conveying pipeline utilizes the characteristic that the top thrust of the elastic member can be adjusted. When the water pressure in the tap water conveying pipeline is greater than the set top thrust, the water flow can be opened. The control valve is configured such that a part of the water flow can be discharged from the gap opened by the control valve, thereby adjusting the pressure of the tap water conveying pipeline, thereby preventing the tap water conveying pipeline from being broken and preventing the tap water conveying pipeline from being subjected to excessive water pressure for a long time. The fatigue is generated, and the service life of the tap water pipeline is further prolonged.

However, the above description is only for the purpose of illustrating the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the new specification. All should remain within the scope of this new patent.
