Abstract
A self-closing anti-siphon trap can be realized through two structures, wherein the structure one comprises a water inlet and a water outlet, between which a piston chamber and an air pressure valve are arranged, the piston chamber is internally equipped with a piston capable of moving up and down, the top end of the piston chamber is connected with the air pressure valve through a positive and negative air pressure proof pipe, the piston chamber is arranged near the water inlet, the air pressure valve is disposed near the water outlet, and the top portion of the piston is provided with a pull-ring. In the structure two, the lower end of a water inlet is provided with a piston chamber, in which a piston capable of moving up and down is disposed, the water inlet is connected with the piston chamber through a water inlet pipe, an air pressure valve is arranged between the water inlet and a water outlet, and the air pressure valve is connected with the top portion of the piston chamber through a positive and negative air pressure preventive pipe.
Description
Technical field
The utility model relates to the trap in a kind of drainage system, relates to a kind of self-closing anti-siphon trap that can prevent that sewage from flowing backwards in particular.
Background technology
Trap generally is installed in the position between sanitary equipment (comprising washing basin, bathtub, bathing pool etc.) and the gutter, effect is to preserve water seal, make the part of joining between the sanitary equipment of each unit and the public blowdown master canal form a foster water level, the dirt that intercepts public main canal flows into indoor.
Trap on the market in case damage, loses the water envelope now, and sewage and dirt will flow into indoor from public blowdown main channel by trap, and not only contaminated environment also can cause the crisis of transmitted virus sometimes.Even the trap of piston apparatus is arranged, when water entered trap, piston still was in the drainage channel of trap, made drainage channel dwindle, and the speed of the draining of slowing down on the one hand makes trap occur silting up on the other hand easily.
Summary of the invention
The purpose of this utility model provides a kind of self-closing anti-siphon trap, by in traditional structure, increasing piston chamber and air pressure valve, can overcome water front cover dawn destruction of the prior art preferably, sewage, dirt blow back into indoor deficiency from public blowdown channel through trap.
The utility model is achieved through the following technical solutions:
One of structure comprises water inlet, delivery port, is provided with piston chamber and air pressure valve between described water inlet and the delivery port, wherein is provided with piston moving up and down in the piston chamber, and the piston chamber top is connected with air pressure valve by anti-positive and negative air-pressure pipe.Wherein piston chamber is arranged on by the water inlet, and air pressure valve is arranged on by the delivery port, and top land is provided with draw ring.
Two of structure, comprise water inlet, delivery port, the lower end of described water inlet is provided with piston chamber, be provided with piston moving up and down in it, water inlet links to each other with piston chamber by water inlet pipe, be provided with air pressure valve between described water inlet and the delivery port, this air pressure valve is connected with the piston chamber top by anti-positive and negative air-pressure pipe, and wherein air pressure valve is arranged on by the delivery port.
The beneficial effects of the utility model are: sealing is strong, low production cost.Piston apparatus can take out so that clean or keep in repair according to actual needs, and can be applied to the trap of different size and shape.

Among the figure, 1 water inlet, 2 pistons, 3 piston chamber, 4 traps bottom, 5 draw rings, 6 anti-positive and negative air-pressure pipes, 7 lattice gas passages, 8 delivery ports, 9 air pressure valves, 10 water inlet pipes.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing 1-4, when water when water inlet 1 flows into trap, be full of the bottom 4 of trap, the pressure of water raises piston 2, lattice gas passage 7 is unimpeded, water flows to delivery port 8 places through each gas passage 7, flows out traps through delivery port 8 then.During entry, piston 2 is pushed among the piston chamber 3, makes the drainage channel volume of trap remain unchanged, and guarantees that draining is unblocked.Simultaneously, when piston 2 rose, the air pressure at its top was higher than the outer air pressure of trap, and anti-positive and negative air pipe by connecting piston chamber 3 tops and air pressure valve 96 is drained air pressure.Wherein the effect of anti-positive and negative air-pressure pipe 6 is exactly the inner and outside air pressure of balance trap.When water stops to flow into trap, piston 2 is because action of gravity descends, and inaccessible lattice gas passage 7 stops sewage and gas to blow back into trap from the delivery port of trap.A handle 5 has been installed at piston 2 tops, and as accumulating dirt in the trap, piston 2 is adhered, and can not move up and down, and again or piston 2 has breakage, draw ring 5 can be smoked, and piston 2 is taken out, so that cleaning or maintenance.
Shown in accompanying drawing 5-6, when water from water inlet 1 when water inlet pipe 10 flows into traps, be full of the bottom 4 of trap, the pressure of water raises piston 2, lattice gas passage 7 is unimpeded, water flows to delivery port 8 places through each gas passage 7, flows out traps through delivery port 8 then.During entry, piston 2 is pushed among the piston chamber 3, makes the drainage channel volume of trap remain unchanged, and guarantees that draining is unblocked.Simultaneously, when piston 2 rose, the air pressure at its top was higher than the outer air pressure of trap, and the anti-positive and negative air pipe 6 that connects piston chamber 3 tops and air pressure valve 9 is drained air pressure.When water stops to flow into trap, piston 2 is because action of gravity descends, and inaccessible lattice gas passage 7 stops sewage and gas to blow back into trap from the delivery port of trap.Can not move up and down as accumulating dirt in the trap, again or piston 2 has breakage, piston 2 can be taken out, so that cleaning or maintenance.
