Description
Technical field
The present invention relates to hydraulic control device, specifically a kind of explosion-proof automatic reducing transformer of running water pipe.
Background technology
Town-property has all been passed through running water pipe, the running water pipe being in each resident family, under faucet closed mode, is subject to certain hydraulic pressure, especially when faucet turns off or on suddenly all the time, running water pipe and faucet in resident family are affected by water hammer, and the pressure born is bigger.Bear, when the water pipe in each resident family and faucet are in, the state that hydraulic pressure is bigger, following several in the case of water pipe or faucet explosion, the problem leaked easily occur: 1, water pipe or faucet because of use long neglected and in disrepair, be on the verge of to damage time；2, when the quality of water pipe or faucet goes wrong；3, when the installation of water pipe or faucet goes wrong；4, when the hydraulic pressure of water system suddenly raises.Under situation unmanned at home, water pipe or faucet burst, leak, and can bring bigger trouble and loss to resident family.
Summary of the invention
It is an object of the invention to provide a kind of explosion-proof automatic reducing transformer of running water pipe, it is arranged on the running water pipe of resident family, when faucet in resident family is closed mode, it can be closed voluntarily, and then by blocking between running water pipe and the upstream of logical resident family, it is lowered into the hydraulic pressure of the running water pipe of resident family.
For achieving the above object, the present invention uses below scheme: the explosion-proof automatic reducing transformer of running water pipe, it has a cylinder body, cylinder body is built with the piston coordinated with it, the front end of piston connects piston rod, the diameter of piston is more than the diameter of piston rod, piston and piston rod make the inner chamber of cylinder body form rod chamber and rodless cavity, connect on cylinder body and have water inlet pipe, water inlet pipe leads to the rod chamber of cylinder body, piston rod is inserted in water inlet pipe, outlet pipe it is connected on water inlet pipe, isocon it is connected on outlet pipe, , isocon connection outlet pipe and the rodless cavity of cylinder body, the front portion of cylinder body has the passage making rod chamber communicate with the external world, prominent limited block it is fixed with on the inwall that cylinder body rodless cavity is relative with piston rear end.
From such scheme, the automatic reducing transformer that the present invention provides is arranged between the running water pipe and the feed pipe of upstream of resident family, make water inlet pipe be water inlet end (connecting with the feed pipe of upstream), outlet pipe be water side (connecting with faucet), when the faucet in resident family is opened, water inlet pipe communicates with outlet pipe, and current are entered by water inlet pipe, flowed out by faucet after outlet pipe；When the faucet is turned off, under the effect of water hammer, piston moves to water inlet pipe direction, by piston rod, the port between water inlet pipe and outlet pipe is closed, make to 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.
Present configuration is simple, rationally, action is accurately, reliably, it is the most when the faucet is turned off, can make to reduce towards the hydraulic pressure in the running water pipe of resident family, avoid running water pipe and faucet because of bear hydraulic pressure relatively big and occur explosion, drainage, and extended in the service life of running water pipe and faucet.

Detailed description of the invention
The present invention 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 the present invention provides has a cylinder body 1, cylinder body 1 is built with the piston 5 coordinated with it, the front end of piston 5 connects piston rod 3, the diameter of piston 5 is more than the diameter of piston rod 3, piston 5 and piston rod 3 make the inner chamber of cylinder body form rod chamber 2 and rodless cavity 6, connect on cylinder body and have water inlet pipe 10, water inlet pipe 10 leads to the rod chamber 2 of cylinder body, piston rod 3 is inserted in water inlet pipe 10, outlet pipe 9 it is connected on water inlet pipe 10, isocon 8 it is connected on outlet pipe 9, isocon 8 connects the rodless cavity 6 of outlet pipe 9 and cylinder body, the front portion of cylinder body 1 has the passage 1c making rod chamber 2 communicate with the external world, prominent limited block 7 it is fixed with on the inwall that cylinder body 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, and cylinder cap 1b couples with the opening of cylinder body 1a, 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 is connected as a single entity with water inlet pipe 10, outlet pipe 9, isocon 8, and cylinder barrel 1a is coaxial with water inlet pipe 10, and piston rod 3 is positioned in the bar segment of rod chamber 2 and has shoulder block 4.
It addition, in the present embodiment, limited block 7 is top in cone, and piston 5 rear end has the center hole 5a coordinated with limited block.When piston 5 rear end and limited block 7 against time, form top coordinating with center hole.
The operation principle of the present invention is further illustrated below in conjunction with Fig. 2, Fig. 3, Fig. 4.
See Fig. 2, the automatic reducing transformer that the present invention provides is arranged between the running water pipe and the feed pipe of upstream of resident family, make water inlet pipe 10 connect with the feed pipe of upstream, outlet pipe 9 connects with running water pipe and the faucet towards resident family, time at faucet in off position, port between water inlet pipe 10 and outlet pipe 9 is closed by piston rod 3, and current stop.
See Fig. 3, when the faucet in resident family is opened, hydraulic pressure in water inlet pipe 10 acts on piston rod 3, atmospheric pressure acts on piston 5, make piston 5 move right to limited block 7 against, water inlet pipe 10 communicates with outlet pipe 9, and current are entered by water inlet pipe 10, 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, the hydraulic pressure of 6 rises, area due to piston 8 rear end is more than the area of piston rod 3 front end, in rodless cavity, hydraulic pressure 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 to the directed force F 1 of piston, i.e. F1 ＞ F2+F3, piston 5 is moved to the left, gradually the port between water inlet pipe 10 and outlet pipe 9 is closed by piston rod 3, be blocked between the running water pipe and the feed pipe of upstream of resident family；During being moved to the left at piston 5, the volume of rodless cavity 6 is gradually increased, and the hydraulic pressure in rodless cavity 6 and outlet pipe 9 is then gradually reduced.Additionally, the moment that port between water inlet pipe 10 and outlet pipe 9 is closed, the hydraulic pressure in rodless cavity 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 is bigger, 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 (seeing Fig. 2), piston 5 stops, in the process, the water in outlet pipe 9 has partial reflux in rodless cavity 6, and the hydraulic pressure in outlet pipe 9 is reduced.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 connect with outlet pipe 9.
By the diameter ratio of appropriate design piston rod with piston, said process can be realized.
