Abstract

The utility model provides a sewage draining self-closing valve of a closet pan. The sewage draining self-closing valve of the closet pan can simplify a structure of a toilet or a squatting pan, requires no trap pipes and is invisibly arranged in a port of a sewage draining pipe at an outlet of sanita. A mechanical lever, a spring and a flush water weight control valve are used in automatic opening and closing of the sewage draining self-closing valve. The valve stores water to form a water seal so that stink can be isolated in the sewage draining pipe as well as resistance to sewage draining is reduced and flush water is saved.

Description

Lavatory pan blowdown self-closing valve

Technical field

The utility model relates to New-type mould moulding materials such as stainless steel, Ya Like, SMC makes the water closet of producing, and the structure of pan and performance optimization provide a kind of lavatory pan blowdown self-closing valve to make it not be with trap, improve water-saving performance.

Background technology

Along with continuing to bring out of new material, new technology, the situation that china sanitary ware rules all the land is broken, and makes the sanitaryware of producing with New-type mould moulding materials such as stainless steel, Ya Like, SMC and more and more is subject to pursuing of market.China sanitary ware adopts burning process, does not possess re-workability after the moulding, and the quality precision is difficult to guarantee.And the sanitaryware of the New-type mould moulding materials such as stainless steel, Ya Like, SMC all are through mechanical mold pressing processing and fabricating, steady quality, and machining accuracy is high, possesses re-workability after the moulding, has created condition for making brand-new water-saving type sanitary accessories for closet.The water resources crisis that particularly occurs in the social fast development becomes the economic development of serious restriction China, has a strong impact on people's lives.In the face of this stem reality, various water-saving type sanitary accessories for closets emerge in succession, but water closet, pan as " spending freely " water resource " rich and influential family " in the life, although no matter be that new material is made or all the improving take water saving as purpose of traditional porcelain all the time, but do not break through all the time the form of trap water seal blowdown, all be between urinal and blow-off line, to be designed with the trap structure, be product itself with trap, or be exactly that the blow-off line interface is provided with trap.The effect of trap mainly is to utilize to remain in the trap that certain water level cuts off blow-off line and urinal, prevents that the foul smell string in the blow-off line is extremely indoor.But the trap structure has not only strengthened the manufacture difficulty of product, and increased the resistance of blow-off line, cause blowdown not smooth, even stop up, water in the trap what with certain dirt, to make indoor generation peculiar smell, just to need to cause the waste of water resource with more water even repeatedly bath in order rinsing well.

Summary of the invention

Unobstructed in order to realize making water closet, the pan blowdown of producing with New-type mould moulding materials such as stainless steel, acrylic, SMC, the wash water of minimizing water closet, pan produces brand-new water-saving product.The utility model provides a kind of lavatory pan blowdown self-closing valve, and this self-closing valve can not only water seal in the situation that does not need trap cuts off the foul smell in the blow-off pipe, and ight soil and dirt are flung to blow-off pipe with water.Thereby simplification water closet, squatting pan structure have been realized, have reduced manufacture difficulty, save manufacturing cost that in line unobstructedly do not stop up reduced wash water, saving water resource.

The technical scheme that its technical problem that solves the utility model adopts is: make water closet, the pan of producing with New-type mould moulding materials such as stainless steel, acrylic, SMC, utilize its manufacturing technology and can reprocess characteristic be made into be not with trap, simple in structure, produce simple and easy, can with the supporting brand-new water-saving product of lavatory pan blowdown self-closing valve.Lavatory pan blowdown self-closing valve design grade, radian and urinal end opening suitable for reading is complementary and forms superimposed sealing surface, superimposed sealing surface is through the similar valve sealing of mechanical lapping, be laid with bayonet socket around the urinal end opening, lavatory pan blowdown self-closing valve sealing surface correspondence position suitable for reading is provided with buckle, smear seal grease on the sealing surface when installing and changing, the bayonet socket that buckle on the lavatory pan blowdown self-closing valve is aimed at urinal firmly depresses and screwing hermetic is fixed, in the hidden blow-off pipe interface that is contained in the urinal outlet.

Lavatory pan blowdown self-closing valve is comprised of valve body, valve, mechanical lever and spring, pivot pin etc.Valve body, valve adopt the New-type mould moulding materials such as the stainless steel consistent with the urinal material, acrylic, SMC through mechanical mold pressing machine-shaping.Valve body is up big and down small camcylinder structure, valve then tips upside down on the end opening of valve body like circular bottle cap, eccentric position, valve bottom links to each other with pivot pin with mechanical lever, the mechanical lever other end links to each other with pivot pin with spring, the middle part of mechanical lever links to each other with pivot pin with the valve body upper bracket, the other end of spring links to each other with pivot pin with the valve body upper bracket, mechanical lever, spring and pivot pin are stainless steel products, rely on mechanical lever and this easy device of spring to make valve close the formation self-closing valve, then rely on weight and the lower punch power of water automatically to open valve during flushing, ight soil and dirt are with falling under water, the flushing end is along with water heavily reaches reducing automatic-closing valve and utilizing remaining water water seal airtight of lower punch power.

The beneficial effects of the utility model are: simplify water closet, squatting pan structure, reduce manufacture difficulty, save manufacturing cost.In line unobstructedly do not stop up reduced wash water, saving water resource.Be applied on the lavatory pan of train, can also prevent that valuables from dropping from the urinal mouth.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is vertical section of the present utility model constructional drawing

Fig. 2 is the assembling drawing of the utility model embodiment

Among the figure 1, valve body; 2, valve; 3, mechanical lever; 4, spring; 5, urinal; 6, superimposed sealing surface; 7, buckle; 8, blow-off pipe interface.

The specific embodiment

In Fig. 1, valve body (1) relies on mechanical lever (3) and this easy device of spring (4) to utilize the precompression of spring (4) to make valve (2) close the formation self-closing valve with valve (2).

In embodiment illustrated in fig. 2, lavatory pan blowdown self-closing valve and urinal (5) rely on superimposed sealing surface (6) to smear the formation sealing that is tightened that seal grease adds assembly force and buckle (7).Under normal circumstances, the precompression of spring (4) is in order to the weight of jacking valve (2), water and ight soil, during flushing the toilet after use, valve (2) heavily reaches at water under the stack of lower punch power in case namely automatically open into skewed greater than the precompression of spring (4), with ight soil and dirt by being flushed under water in the blow-off pipe interface, the flushing end, water heavily reaches lower punch power and reduces gradually, valve (2) automatically resets under the effect of mechanical lever (3) and spring (4) and closes, and it is airtight to utilize remaining water to form water seal.
