Abstract

The utility model relates to an anti-smell and anti-overflow floor drain. The utility model is composed of an adjusting sleeve, a water grate, an annular water storing groove which is formed by the combination of an inner cylinder, a flow guiding hood arranged above the inner cylinder and a valve composed of a valve cylinder, a valve plate and a heavy hammer, wherein, a sealed water seal is formed by the flow guiding hood and the water storing groove, and the other end of the water seal is provided with the heavy hammer. When water is not discharged from the valve, the valve plate is stuck and sealed on the valve cylinder under the action of the heavy hammer. When water is discharged from the valve, water overflows on the valve plate via the water seal, and the valve plate is opened under the function of gravity to accomplish the discharging of water. Because the utility model has the two sealing functions of water sealing and mechanical contact sealing, the utility model has the advantages of thorough sealing, convenient installation, convenient cleaning, low cost, etc.

Description

High water seal back-spill preventing floor drain

The utility model relates to a kind of floor drain that discharges indoor waste water, is communicated with sewer, and the floor drain of the check valve that stops return of waste water is particularly arranged.

Existing floor drain in order to reach deodorization, the excessive purpose of counnter attack, can be divided into two classes; One class is the hydrolock floor drain, and it utilizes the interior water of water storage bowl to stop on the interior foul odour of sewer and escapes; But, can not keep the water seal situation for a long time, and to the anti-excessive interception that do not have of the sewage in the sewer because water seal is more shallow.Another kind of is the floor drain that has check valve, although this floor drain can stop anti-spilling water effectively, but it is indoor to still have the part foul smell to escape in drainage procedure, is that the patent that CN2144145Y, name are called " lever automatic open-close downspout device " just belongs to this class as the notification number of Patent Office of the People's Republic of China 1993 bulletin.

The utility model provides a kind of simple in structure at the problems referred to above, deodorization effectively, the floor drain that again can counnter attack overflows.

The purpose of the utility model realizes by following technical proposals: it comprises the overcoat that has inner core, is actively connected on the outer adjustment cover that puts, and is contained in to adjust the water grate that puts and place the kuppe between water grate and the inner core to form.Inner core and overcoat are made one, and constitute the annular groove of water, and the kuppe periphery places in the shape ring groove, and constitute a deep water envelope with water in the annular groove.On the above-mentioned inner core valve cylinder is housed, the valve cylinder outer wall is provided with support, and rotating shaft is connecting valve plate on the support, and valve plate and valve cylinder lower port fit and form sealing, and the other end of valve plate has a weight; During not draining, valve plate closely is sealed on the valve cylinder under the action of gravity of weight; During draining, water overflows on the valve plate of valve cylinder through the groove of water, and under the situation of displaced weight greater than weight weight, valve plate is opened, and sewage enters sewer pipe rapidly; After sewage drained, valve plate returned to original closure state again automatically under the effect of weight, thereby stoped effectively in insect, the anti-excessive sewage inlet chamber.

The utility model forms water seal and the mechanical two seals effect that contacts driving fit, thereby has avoided the effusion of foul smell, fuel gas in the drainage procedure because the waste water water seal of process groove earlier when draining overflows to valve cylinder again.Compared with the prior art it have sealing thoroughly, and it is convenient to install, clear up, and low cost and other advantages is particularly suitable for being installed on washroom, the kitchen surface, with the supporting use of sewer pipe.

Below in conjunction with embodiment shown in the drawings the utility model is further described.

Fig. 1 is the not structural representation during draining of the utility model.

Referring to Fig. 1, high water seal back-spill preventing floor drain is by the overcoat 1 that has inner core 3, be threaded in the adjustment cover 11 on overcoat 1 port, be embedded in and adjust on the cover 11 and, be fixed on the kuppe 2 below the water grate and be contained in automatic open and close valve composition on the inner core 3 with bolt 6 with it at conplane water grate 10.

Overcoat 1 upper end inwall is shaped on internal thread and cooperates with adjustment cover 11, the lower end has tube connector 12, be connected with sewer pipe, overcoat 1 is made one with inner core 3, and forms the annular groove 9 of a water, and kuppe 2 is made garden tubular or dome shape, over against inner core 3 tops, its circumference places in the groove 9, when guaranteeing groove 9 waters, forms airtight water seal.

The automatic open and close valve comprises the taper valve cylinder 4 that is contained on the inner core 3, and valve cylinder 4 upper end outer walls can be equipped with O-ring seals, with 3 close joining of inner core; Valve cylinder 4 outer walls are being fixed support 7, and rotating shaft is connecting valve plate 5 on the support 7, and the shape of valve plate 5, size and valve cylinder 3 lower port are complementary, and can evenly paste and touch, and form sealing; The other end of valve plate 5 is being fixed weight 8, and when not draining, valve plate 5 closely is sealed in valve cylinder 3 lower port under weight 8 actions of gravity, and when displaced weight during greater than weight 8, valve plate 5 is opened, and sewage enters down pipeline.

When the utility model is installed, earlier overcoat 1 and sewer pipe are connected, with cement hole that ground led to and the gap between the overcoat 1 are filled again, then, according to ready-made ground level position, adjust cover 11 height well with threaded adjustment, irritated fixing with cement again, like this, can overcome the contradiction that different for many years work post constructions are difficult for cooperation.

Obviously, the utility model, has prevented in the inlet chambers such as insect, foul smell, fuel gas so both increased the sealing performance of floor drain because deep water envelope and automatic open and close valve are combined, and has avoided the anti-of sewage to overflow again effectively.It is the auxiliary equipment of present comparatively ideal sewer pipe deodorization anti-spill-out.

The used material of the utility model diagram is overall plastic material, but also can be cylinder iron, mixed materials such as copper, stainless steel, ABC engineering plastics constitute.
