Abstract

The utility model discloses a water sealing and protecting structure, which comprises a sealed outer cover; wherein, the sealed outer cover has a faceplate inside, and the faceplate has at least one hole that has a flat and smooth hole socket; the lower part of the hole socket has a shaft hole and the upper part of the hole socket has a valve flap that has a stand shaft that is inserted into the inner valve flap of the shaft hole at the lower part of the hole socket to seal the hole. The sealed outer cover also has an intracavity with a pipe at the lower part; wherein, the pipe is connected with a water discharging pipe net. When a negative pressure appears in the water discharging pipe, the inner part and the outer part of the sealed outer cover form a pressure deviation. The air pressure rises up the valve flap from the lower part of the hole and then enters into the intracavity. Later, the air pressure straightly reaches the water discharging pipe net to charge in the air along the pipeline, to further realize the aim of protecting the water sealing safety of the sanitary installation. The utility model has the advantages of simple structure, excellent protecting performance of the water sealing, high sensitivity, and low cost as well as high practicability.

Description

A kind of water seal protective valve
Technical field
The utility model relates to a kind of water seal protective device that is used for the building water-wastewater system.
Background technology
The so-called Togo import inlet valve of domestic a large amount of uses at present belongs to the monolithic valve body, and the rubber bad sealing is easy to wear, and gas leakage is big, and product sensitivity is not high, thereby shallow water envelope utensil is failed to bring into play the water seal protective effect, and cost is also higher.
Summary of the invention
The purpose of this utility model is to provide the water seal protective valve that a kind of water seal protective value is good, highly sensitive, cost is low.
A kind of water seal protective valve that the utility model provides, comprise a seal casinghousing, has a panel in the seal casinghousing, at least be provided with an aperture on the panel, have a smooth smooth hole seat on the aperture, the bottom of hole seat is provided with an axis hole, and the top of hole seat is equipped with a flap, flap has a vertical shaft, and the interior flap of axis hole that vertical shaft is inserted in seat bottom, hole seals the aperture; Also have an inner chamber in the seal casinghousing, the bottom of inner chamber is provided with conduit, and conduit connects drainage pipeline networks.When negative pressure appears in drainage pipeline networks, the inside and outside formation pressure reduction of seal casinghousing, atmospheric pressure backs down flap from the bottom, aperture, enters inner chamber then, replenishes atmosphere along the through drainage pipeline networks of conduit again, eliminates negative pressure, thereby reaches to protection sanitary equipment water seal security purpose.
For avoiding flap displacement and air-flow to damage flap, the periphery, top of the utility model hole seat is provided with guardrail, and flap is positioned at guardrail.
According to actual needs, the utility model can be provided with a plurality of apertures, hole seat, above the seat of hole flap is installed.
The utility model is not only simple in structure, the water seal protective value is good, highly sensitive, and cost is low, has advantages of high practicability.
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a longitudinal plan of the present utility model;
Fig. 2 is a flat sectional drawing of the present utility model.
The specific embodiment
The utility model water seal protective valve, comprise a seal casinghousing 1, have a panel 2 in the seal casinghousing 1, panel 2 upper edge perimeter rows are shown four apertures 3, has a smooth smooth hole seat 4 on the aperture 3, the bottom of hole seat 4 is provided with an axis hole 5, and the top of hole seat 4 is equipped with a flap 6, and the periphery, top is provided with guardrail 11, flap 6 is positioned at guardrail 11, flap 6 has a vertical shaft 7, and vertical shaft 7 is inserted in the axis hole 5 of hole seat 4 bottoms, and flap 6 just can tightly be pressed in above the hole seat 4 aperture 3 sealings; Also have an inner chamber 8 in the seal casinghousing 1, the bottom of inner chamber 8 is provided with conduit 9, and conduit 9 connects drainage pipeline networks 10.When negative pressure appears in drainage pipeline networks 10, seal casinghousing 1 inside and outside formation pressure reduction, atmospheric pressure backs down flap 6 in 3 bottoms from the aperture, enters inner chamber 8 then, replenishes atmosphere along conduit 9 through drainage pipeline networks 10 again, eliminates negative pressure, thereby reaches to protection sanitary equipment water seal security purpose.
