For achieving the above object, this utility model uses below scheme: the explosion-proof automatic reducing transformer of running water pipe, it has one
Cylinder body, cylinder body is built with the piston coordinated with it, and the front end of piston connects piston rod, and the diameter of piston is straight more than piston rod
Footpath, piston and piston rod make the inner chamber of cylinder body form rod chamber and rodless cavity, and cylinder body connects water inlet pipe, water inlet pipe and cylinder body
Rod chamber lead to, piston rod is inserted in water inlet pipe, and water inlet pipe is connected to outlet pipe, and outlet pipe is connected to isocon, isocon
Connection outlet pipe and the rodless cavity of cylinder body, the front portion of cylinder body has the passage making rod chamber and the external world communicate, cylinder body rodless cavity
Prominent limited block it is fixed with on the inwall relative with piston rear end.
From such scheme, the automatic reducing transformer that this utility model provides is arranged on towards resident family running water pipe with
Between the feed pipe of upstream, make water inlet pipe be water inlet end (connecting with the feed pipe of upstream), outlet pipe be that water side is (with faucet
Connect), when the faucet in resident family is opened, water inlet pipe communicates with outlet pipe, current by water inlet pipe enter, after outlet pipe by
Faucet flows out；When the faucet is turned off, under the effect of water hammer, piston moves to water inlet pipe direction, will by piston rod
Port between water inlet pipe and outlet pipe is closed so that be blocked between the running water pipe and the feed pipe of upstream of resident family, and
The hydraulic pressure entering the running water pipe of resident family is reduced largely.
This utility model is simple and reasonable for structure, and accurately, reliably, it can make to lead to the most when the faucet is turned off in action
Reduce toward the hydraulic pressure in the running water pipe of resident family, it is to avoid running water pipe and faucet because of bear hydraulic pressure relatively big and occur explosion,
Drainage, and the service life of running water pipe and faucet is extended.

Detailed description of the invention
This utility model is further illustrated below in conjunction with embodiment and accompanying drawing.
See Fig. 1
The explosion-proof automatic reducing transformer of running water pipe that this utility model provides has a cylinder body 1, and cylinder body 1 coordinates built with it
Piston 5, the front end of piston 5 connects piston rod 3, and the diameter of piston 5 is more than the diameter of piston rod 3, piston 5 and piston rod 3
The inner chamber making cylinder body forms rod chamber 2 and rodless cavity 6, and cylinder body connects water inlet pipe 10, water inlet pipe 10 and the rod chamber 2 of cylinder body
Logical, piston rod 3 is inserted in water inlet pipe 10, and water inlet pipe 10 is connected to outlet pipe 9, and outlet pipe 9 is connected to isocon 8, isocon 8
Connection outlet pipe 9 and the rodless cavity 6 of cylinder body, the front portion of cylinder body 1 has the passage 1c making rod chamber 2 and the external world communicate, cylinder body
Prominent limited block 7 it is fixed with on the inwall that rodless cavity 6 is relative with piston 5 rear end.
In the present embodiment, cylinder body 1 is made up of cylinder barrel 1a and cylinder cap 1b connection, the one end open of cylinder barrel 1a, cylinder cap 1b and cylinder
The opening of body 1a couples, and the rear end of piston 5 is relative with cylinder cap 1b, and limited block 7 is surveyed in being fixed on cylinder cap 1b.Cylinder barrel 1a with enter
Water pipe 10, outlet pipe 9, isocon 8 are connected as a single entity, and cylinder barrel 1a is coaxial with water inlet pipe 10, and piston rod 3 is positioned at the bar of rod chamber 2
There is on Duan shoulder block 4.
It addition, in the present embodiment, limited block 7 is top in cone, and piston 5 rear end has and coordinates with limited block
Center hole 5a.When piston 5 rear end and limited block 7 against time, form top coordinating with center hole.
Operation principle of the present utility model is further illustrated below in conjunction with Fig. 2, Fig. 3, Fig. 4.
See Fig. 2, the automatic reducing transformer that this utility model provides is arranged on the running water pipe towards resident family and upstream
Between feed pipe, make water inlet pipe 10 connect with the feed pipe of upstream, outlet pipe 9 with towards the running water pipe of resident family and faucet phase
Connecing, time at faucet in off position, the port between water inlet pipe 10 and outlet pipe 9 is closed by piston rod 3, and current stop.
Seeing Fig. 3, when the faucet in resident family is opened, the hydraulic pressure in water inlet pipe 10 acts on piston rod 3, atmospheric pressure
Power acts on piston 5 so that piston 5 move right to limited block 7 against, water inlet pipe 10 communicates with outlet pipe 9, current by
Water inlet pipe 10 enters, is flowed out by faucet after outlet pipe 9.
See Fig. 4, when the faucet is turned off, under the effect of water hammer, in water inlet pipe 10, outlet pipe 9 and rodless cavity 6
Hydraulic pressure rise, owing to the area of piston 8 rear end is more than the area of piston rod 3 front end, the hydraulic pressure effect to piston in rodless cavity
Power F1 is more than the water inlet inner pipe water pressure directed force F 2 to piston rod with air to piston directed force F 3 sum, i.e. F1 ＞ F2+F3, lives
Plug 5 is moved to the left, piston rod 3 gradually closed by the port between water inlet pipe 10 and outlet pipe 9, towards resident family running water pipe with
It is blocked between the feed pipe of upstream；During being moved to the left at piston 5, the volume of rodless cavity 6 is gradually increased, without bar
Hydraulic pressure in chamber 6 and outlet pipe 9 is then gradually reduced.It addition, the moment that the port between water inlet pipe 10 and outlet pipe 9 is closed, nothing
Hydraulic pressure in bar chamber 6 and water inlet pipe 10 is identical, owing to the area of piston 5 is more than the end area of piston rod 3, piston 5 stress
Relatively big, piston 5 may proceed to be moved to the left, and the volume of rodless cavity 6 also continues to increase, when shoulder block 4 and cylinder barrel against after (see figure
2), piston 5 stops, and in the process, the water in outlet pipe 9 has partial reflux in rodless cavity 6, and the hydraulic pressure in outlet pipe 9 obtains
To reducing.When piston rod 3, the port between water inlet pipe 10 and outlet pipe 9 is completely enclosed in above process, shoulder block 4 and cylinder barrel 1a
Against rear, piston stop motion.Hereafter being again turned on faucet, piston 5 can move right again again, makes water inlet pipe 10 and water outlet
Pipe 9 is connected.
By the diameter ratio of appropriate design piston rod with piston, said process can be realized.
