Abstract

The utility model relates to an inserted siphon discharge fitting which comprises a lifting cavity, a water feeding pipe connected to the lifting cavity, a lifting rod and a water discharging pipe, wherein, the lifting rod is contained in the lifting chamber, the water discharging pipe and the outer wall of the lifting chamber form a half inserted shape, and the half of the lifting rod is exposed out of the wall body of the lifting chamber for forming an inserted structure. The utility model which is combined with the advantages of a common siphon discharge fitting and the advantages of a bell type siphon discharge fitting has the advantages of simple structure, small size, high siphon sensitivity and small energy loss. In addition, the utility model which can be matched with a national standard water tank is unexampled by a general siphon discharge fitting.

Description

Inserted siphon discharge fitting part

The utility model relates to a kind of low case siphon drainage accessory, especially a kind of inserted siphon drainage accessory.

Common siphon drainage accessory on the market in the past, it promotes chamber and separates with sewer pipe, so shared volume is big in casing, be unsuitable for putting into the water tank that meets country's " sanitary ceramics " standard, and because structure is disperseed poor sealing performance, influence drainage speed, make troubles to the user.

Once disclosed a kind of siphon drainage accessory of bell-jar in No. the 916678th, the Russian Patent, the characteristics of this accessory are that sewer pipe is placed in and promotes in the chamber, and the volume of drainage fitting has just dwindled like this.But promote in the chamber because sewer pipe directly is placed in, thus during draining water to carry out the transition to sewer pipe in the chamber very unexpected from promoting, therefore cause siphon sensitivity not high, and defective such as energy loss is bigger.

The purpose of this utility model will overcome the structural shortcoming of above-mentioned various drainage fitting exactly, designs a kind ofly can make volume-diminished, can improve siphon sensitivity again, reduces the siphon drainage accessory of energy loss.

For achieving the above object, design of the present utility model is as follows:

A kind of low level cistern siphon drainage accessory, comprise that one promotes the chamber, one is connected in the upper hose that promotes on the chamber, one is included in a lifting arm and a sewer pipe that promotes in the chamber, described sewer pipe is made with the outer wall that promotes the chamber and is become half embedding shape, has half to expose and promotes the chamber wall body, becomes an embedded structure, described sewer pipe center is to promoting the center, chamber and becoming 36 degree angles to promoting upper hose mouth center, chamber, described lifting arm projection centre and lifting chamber center-biased one distance (6 millimeters).

Advantage of the present utility model is to combine the advantage of common siphon drainage accessory and bell-jar accessory, and simple in structure, volume is little, can with the supporting use of the water tank that meets national standard, and siphon is highly sensitive, and energy loss is few, for general siphon drainage accessory can not be compared.

For further understanding architectural feature of the present utility model, existing accompanying drawings is as follows:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a right view of the present utility model;

Fig. 3 is a vertical view of the present utility model;

Referring to Fig. 1 and Fig. 2, the utility model low level cistern siphon drainage accessory comprises that one promotes chamber 1, one is connected in the last water bend pipe 2 that promotes on the chamber, one is installed in the riser 6 that promotes in the chamber, one is included in the lifting arm 3 in the described lifting chamber 1, one end of this lifting arm 3 is fixed with the riser 6 that promotes in the chamber 1 by

nut

4 and 5, the other end slidably passes the apical pore 13 that promotes chamber 1, and be connected with eyenut 7 in the end, can link to each other with the follower lever (not shown) of water tank spanner by this nut, a weight 8 passes lifting arm 4 and is placed on the riser 6; One sewer pipe 9 is made and is become half embedding shape with the outer wall that promotes chamber 1, there is half to expose the wall body that promotes chamber 1, become an embedded structure, the top of sewer pipe also is provided with a bend pipe 10 that is communicated with sewer pipe 9, referring to Fig. 3, the center A of sewer pipe 9 is to promoting chamber 1 center B and becoming 36 degree angles to promoting chamber 1 upper hose, 2 mouth of pipe center C, and compact conformation can match with the standard water tank like this.

In addition, as shown in Figure 3, lifting arm projection centre D and lifting center, chamber B setover one apart from t, in the utility model be 6 millimeters, when lifting arm 3 spurs like this, power is operated upon by on the position of centre of gravity of riser 6, be unlikely to take place riser 6 unbalance stress phenomenons, and bend pipe 2 can not collided yet with follower lever.

See also Fig. 2 again, siphon drainage accessory of the present utility model also is provided with a water seal storehouse 11 around the apical pore 13 that promotes chamber 1, defectives such as, gas leakage big with the noise that prevents from that liquid from having air to enter in the ring process that contracts, overcome to adopt in the past the sealing of asphaltic felt or rubber seal to bring and life-span are short.

In addition, be provided with a moisturizing hole 12 in bend pipe 10 1 sides of sewer pipe 9, aging to prevent rubber tube, cause draining valve to leak.

The lifting cavity of the utility model siphon drainage accessory all adopts thin-wall part, and volume is little, is suitable for ceramic water tank and matches.

Claims

1, a kind of inserted siphon drainage accessory, comprise that one promotes the chamber, one is connected in the upper hose that promotes on the chamber, one is included in a lifting arm and a sewer pipe that promotes in the chamber, it is characterized in that described sewer pipe is made with the outer wall that promotes control becomes half embedding shape, has half to expose and promotes the chamber wall body, becomes an embedded structure, described sewer pipe center is to promoting the center, chamber and becoming 36 degree angles, described lifting arm projection centre and lifting chamber center-biased one 6 mm distance to promoting upper hose mouth of pipe center, chamber.

2, siphon drainage accessory as claimed in claim 1 is characterized in that being provided with a water seal storehouse around the apical pore of described lifting chamber.

3, siphon drainage accessory as claimed in claim 1 is characterized in that described sewer pipe bend pipe one side is provided with a moisturizing hole.
