The utility model comprises a cylinder body, and a movable cover plate, wherein, the cylinder body is hollow, and the cover plate is assembled at the lower part of the cylinder body; seal rubber sheets are arranged between the cylinder body and the movable cover plate; the left end of the movable cover plate is provided with a matching block; the upper part of the cylinder body is provided with a flange ring; the lower part of the cylinder body is provided with a rust prevention pinhole which is installed in a rust prevention inserting pinhole.
Description
This practical water-saving kitchen, washroom deodorization anti-overflow one way valve relate to is that a kind of kitchen, washroom sewer of preventing gives out foul smell and pipeline stops up because of foreign matter or septic tank overflows overflowing to indoor of causing to indoor, to the protection of home environment.
Can the foul smell (some family diffuses out from three building water closets, and sewage drops down Stall always) that low floor washroom overflows and the kitchen sewer pipe gives out looks for the people to dredge again, find in advance to prevent.Several years ago, a kind of existing deodorization anti-overflow device has appearred, it is under a round plastic mouth of pipe, with the fixing identical thin plastic sheet of size that flushes with this mouth of pipe of screw, dress is formed under the water closet, when leaving behind Cistern valve, the pressure of water is washed about 45 degree plastic tab open and is arranged down, and bath finishes, and thin slice is because of elastic reset, sewer pipe and air are isolated, practical saying, it still is passable beginning to load onto, but has used less than 1 year, when the above level in the 5th buildings is washed by water, send bigger bubble sound and foul smell in the water closet.
Known to the applicant, present commercially available deodorization anti-overflow device, prior art exists weak point to be: 1, the every bath of this plastic sheet once, will tension and relaxation once, easily aging, ferrule increases gradually, sewer pipe and air can not be isolated.2, as because of carelessness, pour hot water into, can make the thin slice distortion.3, to guarantee each bath after, thin slice can rebound, and will get well thickness and elasticity in the selection, comparatively speaking, it is big that the pressure of bath is wanted.Therefore, whenever install this product after, the water tank ball float will be heightened, concerning one family, everyone one day bath secondary, whole family's water rate in January spending will increase.
The purpose of this utility model is the deficiency that exists at present deodorization, anti-overflow device, and a kind of water-saving kitchen, washroom deodorization anti-overflow one way valve are provided.
Water-saving kitchen, the washroom deodorization, the anti-overflow one way valve takes following scheme to realize, mainly has cylinder body, removable cover, its cylinder body and removable cover are by the one-shot forming of hard pvc tubing (PVC) thermoplastic, cylinder body hollow, the flange circle is arranged at the top that cylinder body connects together, inferior part of the cylinder block has antirust pin hole, removable cover is contained in inferior part of the cylinder block, between cylinder body and the removable cover diaphragm seal is arranged, cover plate left end device has balancing weight, cylinder body and removable cover are assembled into one, because antirust pin and hole are movingly, the antirust pin that cylinder body is connected with removable cover can be considered the fulcrum of a lever in point, cover plate right-hand member weight is greater than left end, and cover plate is to right-hand member inclination 90 degree (the cover plate position of dotted line among Fig. 1).Because the cover plate left end has been fixed balancing weight with screw, make its cover plate keep balance, this cylinder is loaded in the toilet seat organ pipe blocks up to the cylinder body upper flange, peripheral water mudding is good, just often, be in closed state, sweep away if any little water, the removable cover disequilibrium tilts, and bath finishes, removable cover restores balance, and air and sewer cut off.When stopping up, because of being subjected to the cylinder body lower end, removable cover stops, and sewage can only be arranged down, can not reflux, and can dredge the obstruction point ahead of time, has reached that economize on water in kitchen, washroom, the purpose of deodorization overtopping prevention.
The utility model is described in further detail with enforcement below in conjunction with accompanying drawing.
Fig. 1 is water-saving kitchen, washroom deodorization anti-overflow one-way valve structures schematic diagram.Fig. 2, Fig. 3 are water-saving kitchen, washroom deodorization anti-overflow one way valve cover plate schematic diagram.Fig. 4 is water-saving kitchen, washroom deodorization anti-overflow one way valve cylinder body vertical view.1 is hard pvc material (PVC) material cylinder body in the accompanying drawing 1,2 for fixing hard pvc cover screw and balance weight iron (obliquity), 3,5 is removable cover, screw, balance weight iron position just often, 4 box out for cylinder body gives, the 6th, waterproof rubber (connecting) with resin, 7 removable covers, the flange that 8 cylinder bodies connect together (being stuck in the mouth of pipe).1 is cover plate in the accompanying drawing 2,3, and 2 are anti-pin pin hole, and 3 is fixed weight iron hole on the removable cover.1 just in time is stuck in the mouth of pipe for cylinder upper flange dish size in the accompanying drawing 4, and 2,3 are connected pin hole for giving the fixedly removable cover that stays with cylinder body.
With reference to accompanying drawing, water-saving kitchen, washroom deodorization, anti-overflow one-way valve structures have cylinder body 1, removable cover 7, and cylinder body 1 is a hollow, and flange circle 8 is arranged at cylinder body top, be used for cylinder body is contained in pipeline opening, inferior part of the cylinder block has antirust pin hole 4, and removable cover 7 is contained in cylinder body 1 bottom, between cylinder body 1 and the removable cover 7 the sealed rubber sheet is arranged, removable cover 7 left end device balancing weights 3, adopt screw 5 fixing, antirust latch is contained in the antirust pin hole 4, and cylinder body and removable cover are assembled into one.Engineering plastics such as cylinder body and removable cover employing hard pvc PVC are made.
Toilet seat periphery cement is removed, water-saving deodorization, anti-overflow check valve are put into down The water pipe road junction is fixed with cement to flange circle place, and toilet seat resets. Drain of kitchen is former by this The reason minification, cancellation flange circle can normally use. Its advantage is: 1, flat owing to what adopt Weighing apparatus principle, little water can make removable cover tilt using water wisely. Even 2 mistakes are hot water, Can not be out of shape. 3, a little screw is done antirust processing, prolongs the pot life, reaches kitchen, health Between deodorization, anti-overflow, keep good air ambient.
