Abstract

The utility model relates to a water supply selecting device from running water and ponds, which comprises a water supply pipe, a water supply branch of pond water, a direct supply branch and equipment water inlet pipe, the water supply branch of pond water, and the direct supply branch are connected in parallel between the water supply pipe and the equipment water inlet pipe; two water supply valves are respectively connected with a water drainage of the water supply branch of pond water, and the direct supply branch in series; a branch with a pressure discharging valve and a water pressure meter is arranged between the two water supply valves which are connected in series. The device adds the anti-leakage and anti-overflow reliability, makes full use of running water pressure, prevents pond pressure pumps from continuously running, and saves resources.

Description

Tap water and tank water water supply selecting arrangement

The utility model relates to a kind of tap water and tank water water supply selecting arrangement.

Too busy to get away water, the Running-water Company of people in daily life and activity in production provides the mode of water to have plenty of direct supply by city's water supply network to people, has plenty of the supply watering equipment; But watering equipment does not fill perhaps and directly joins with running water pipe, this is because when municipal water supply pipe decompression, then may pour in down a chimney the municipal water supply net because of the meeting siphon causes the water of watering equipment, even if there is valve at interval, but also can close the not tight infiltration that produces down, pollute the municipal water supply net because of the quality or the manual operation of valve.For this reason, national Specification city water supply network must ooze the pond of pouring in down a chimney equipment through being provided with anti-siphon, could supply water to watering equipment, because the discharge pressure in pond is not high, can supply with watering equipment mostly after force (forcing) pump is with the water pressurization.

Can so just can not utilize the hydraulic pressure of tap water fully, and force (forcing) pump must ceaselessly turn round power consumption power consumption, increase watering equipment cost.

The purpose of this utility model just provides a kind ofly to be guaranteed to ooze under the refluence prerequisite, can utilize the tap water and the tank water water supply selecting arrangement of tap water hydraulic again fully.

For achieving the above object, the utility model can be taked following technical measures.

The utility model comprises municipal water supply pipe, tank water water system branch, direct-furnish branch and watering equipment water inlet pipe, it is characterized in that: both are parallel to tank water water system branch, direct-furnish branch between municipal water supply pipe and the watering equipment water inlet pipe; In the outlet pipe of tank water water system branch and direct-furnish branch, be in series with two feed water valves respectively; One branch that has purge valve and a water pressure gauge is arranged again between two feed water valves of series connection; The mouth of pipe of watering equipment water inlet pipe is higher than watering equipment, and has an anti-siphon side that has anti-siphon flap valve to manage.

Taked after the above-mentioned technical measures, people are as long as suitably open or close each feed water valve and purge valve, just can freely select to use tap water or tank water to supply with watering equipment,, increase the reliability of antiseepage anti counter-flowing greatly owing to there is the twice feed water valve to check on and the purge valve row pressure.

So made full use of hydraulic pressure from the beginning, avoided the commentaries on classics of not stopping transport of pond force (forcing) pump, saved the energy, and clean the pond also needn't stop to watering equipment water supply, also can set up alternate source.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Accompanying drawing is a front view of the present utility model.

From accompanying drawing, can see, the utility model comprises municipal water supply pipe 1, tank water water system branch 2, direct-furnish branch 3 and watering equipment water inlet pipe 4, it is characterized in that: both are parallel to tank water water system branch, direct-furnish branch between municipal water supply pipe and the watering equipment water inlet pipe; In the outlet pipe of tank water water system branch and direct-furnish branch, be in series with two

feed water valves

21,22 and 31,32 respectively; One branch that has purge valve 23,33 and a water pressure gauge 24,34 is arranged again between two feed water valves of series connection; The mouth of pipe of watering equipment water inlet pipe is higher than watering equipment 5, and has an anti-siphon side that has anti-siphon flap valve 6 to manage.

When people select municipal water supply pipe direct-furnish water, two

relay pumping valves

21,22 on the outlet pipe of tank water water system branch can cut out, and with purge valve 23 unlatchings, by the time when water pressure gauge 24 is designated as zero, open two

relay pumping valves

31,32 of tap water supply pipe again, close purge valve 33, tap water enters the watering equipment pipe, automatically close owing to hydraulic pressure makes anti-siphon flap valve simultaneously, water enters watering equipment; If the then anti-automatic unlatching of siphon flap valve of municipal water supply pipe decompression can be prevented siphon; When people select the pond to supply water, otherwise can close, open each feed water valve and purge valve, can supply water to watering equipment by the pond.Because the tap water supply pipe has the twice water valve to check on, and has increased the reliability of antiseepage anti counter-flowing greatly, added purge valve row pressure, the anti-siphon of flap valve, then several the title is 100% antiseepage refluence safety device.

Just can utilize hydraulic pressure from the beginning fully so at ordinary times, avoid the commentaries on classics of not stopping transport of pond force (forcing) pump, save the energy, and clean the pond also needn't stop to watering equipment water supply, also can set up alternate source.

Claims

1, a kind of tap water and tank water water supply selecting arrangement, comprise municipal water supply pipe, tank water water system branch, direct-furnish branch and watering equipment water inlet pipe, it is characterized in that: both are parallel to tank water water system branch, direct-furnish branch between municipal water supply pipe and the watering equipment water inlet pipe; In the outlet pipe of tank water water system branch and direct-furnish branch, be in series with two feed water valves respectively, a branch that has purge valve and a water pressure gauge is arranged again between two feed water valves of series connection; The mouth of pipe of watering equipment water inlet pipe is higher than watering equipment, and has an anti-siphon side that has anti-siphon flap valve to manage.
