Abstract

The utility model relates to a closet foul discharging valve suitable for direct-flushing squatting water closets. The water source and the drinking water of the direct-flushing squatting water closet are a system in the prior art, and the water source is only started and closed by a hand valve. Bacterium and viruses are easily bred in a pipe, and the water quality of the drinking water is severely influenced. The utility model is provided with a gas discharging cork and a splicing head at the lower end of the hand valve, a gas discharging path and a gas discharging hole are arranged on the gas discharging cork, one end of the gas discharging cork is connected with the hand valve, and the other end is connected with the splicing head. Consequently the utility model has the advantages that the bacterium is not easily bred, the drinking water is not polluted easily, etc.

Description

Closet foul discharging valve

The utility model relates to a kind of valve, the dirty gas drain valve of particularly a kind of closet, and it mainly is applicable to the direct-flushing squatting pan.

When direct-flushing squatting pan of the prior art uses, after the hand valve is opened, water is just directly gone out, excrements is flushed to blow-off pipe again in septic tank, and when the hand valve cuts out, there is not water in one section pipe under the hand valve, at this moment just gas will enter in the pipe, if when running into patient and using the lavatory, bacterium and the viral bacterium bottom that just inevitably can be trapped in hand valve of patient-sized in just, and hand valve bottom is not open to atmosphere confined space, and bacterial virus is the easiest in this breeding, and its result can pollute the water source on top by the hand valve, because washing away the water source and the drinking water of excrements is a system, so it seriously has influence on the water quality of drinking water, especially, stops up by squatting pan when producing, and the situation of its polluted source is just even more serious.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of bacterium and virus to be difficult for breeding, the dirty gas drain valve of the not contaminated closet in water source.

The purpose that the utility model proposed can be achieved through the following technical solutions: this dirt gas drain valve is provided with blow-cook and iron chains joint, has exhaust duct and steam vent on the blow-cook, and an end of blow-cook is connected with the hand valve, and the other end is connected with the iron chains joint.

Description of drawings is as follows:

Fig. 1 is the structural representation of the utility model blow-cook.

Fig. 2 is the sectional view of the utility model blow-cook.

Fig. 3 is a structural representation of the present utility model.

Following the utility model will be described in further detail in conjunction with the accompanying drawings and by embodiment.

Referring to Fig. 1, Fig. 2, blow-cook 1 of the present utility model can be provided with screw thread at two ends, and has exhaust duct 2 and steam vent 3 thereon, so that dirty gas passes through.

Referring to Fig. 3, this dirt gas drain valve mainly is made up of hand valve 4, blow-cook 1 and iron chains joint 5, and an end of blow-cook 1 is connected with hand valve 4, and the other end is connected with iron chains joint 5, and its connection can be to be threaded.

During use, hand valve 4 is linked to each other with oral siphon 6, and iron chains joint 5 is linked to each other with outlet pipe 7.When hand valve 4 cut out, dirty gas will be discharged through steam vent 3 through the exhaust duct 2 between iron chains joint 5 and the blow-cook 1 in a direction indicated by the arrow, thereby communicates with atmosphere, made bacterium and virus be difficult for breeding, and dirty thus gas just can directly not influence the water source yet.

The utility model compared with prior art has the following advantages: because dirty gas can directly enter atmosphere, so bacterium and virus are difficult for breeding, reduced and reduced the pollution at water source in pipeline, guaranteed that people's is healthy.

Claims

1, the dirty gas drain valve of a kind of just gas, comprise the hand valve, it is characterized in that: also be provided with blow-cook (1) and iron chains joint (5), have exhaust duct (2) and steam vent (3) on the blow-cook (1), one end of blow-cook (1) is connected with hand valve (4), and the other end is connected with iron chains joint (5).

2, dirty gas drain valve as claimed in claim 1 is characterized in that: available being threaded that be connected of blow-cook (1) and hand valve (4) and iron chains joint (5).
