Abstract
A floor drain for a vacuum drainage system comprises a grate, a casing and a water filter component, wherein the water filter component includes a water filter, a rubber diaphragm and a cover board, the rubber diaphragm is fixed onto the water filter through the cover board, a sealed cavity is formed between the upper side of the rubber diaphragm and the water filter, both the upper portion and the lower periphery of the water filter are provided with water through holes, a passage is formed between the upper portion of the water filter and the rubber diaphragm, a drain pipe is arranged on the lower portion of the casing, the drain pipeline projects over the bottom face of the casing via a certain height, the rubber diaphragm tightly contacts with the drain pipe when the water filter component is fixed onto the casing, and the grate is directly placed on the casing. The floor drain has the advantages that the grate and the water filter double-layer filtering component designed can effectively prevent pipeline blockage, and reduce cleaning and maintenance times, the floor drain directly connected to a vacuum pipeline avoids easy blockage and water returning, part of stored water constantly reserved in the casing can function in secondary sealing and odor avoidance, and effectively prevent drying, and the floor drain is convenient in use and simple in maintenance.
Description
Technical field
The utility model relates to a kind of floor drain, particularly a kind of floor drain that is used for vacuum row guiding systems.
Background technology
The disclosed drainage system of Chinese patent literature CN201512858U vacuum floor drain apparatus, comprise at least one gravity floor drain, the gravity floor drain is connected with vacuum plant by the buck connecting line, vacuum plant comprises control module, the end of buck connecting line is grey water out, be provided with bleed valve on the buck connecting line in buck exit, electromagnetic valve is connected with the vacuum pipe network with bleed valve by the vacuum control flexible pipe; Also be provided with liquid-level switch on the buck connecting line, described buck connecting line is provided with blow vent, and blow vent is arranged on the liquid-level switch place, and described liquid-level switch adopts the electric pole type liquid-level switch.This vacuum floor drain apparatus divides by pipeline and links to each other with the vacuum pipe network, can realize that the vacuum type that the vacuum floor drain is produced buck collects automatically, has solved the deficiency of existing building low-pressure drainage system usefulness vacuum floor drain apparatus, but its complex structure, uses and controls very complicated.
The utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of floor drain that is used for vacuum row guiding systems is provided, make it not need control, can be according to the automatic draining of the situation of water level, and possess good draining, sealing, anti-foul smell, anti-water, the anti-dry and anticlogging advantage returned.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of floor drain that is used for vacuum row guiding systems comprises grate, housing, water filter assemblies; Water filter assemblies comprises water strainer, diaphragm of rubber, cover plate, diaphragm of rubber is fixed on the water strainer by cover plate, forming a seal chamber above the diaphragm of rubber and between the water strainer, water hole is all arranged water strainer top and next week, water strainer top to diaphragm of rubber place forms passage; Lower housing portion is provided with drainage pipe, and gutter projects upwards housing bottom surface one height, and diaphragm of rubber closely contacted with gutter when water filter assemblies was fixed on the housing; Grate directly is put on the housing.
Design is jagged on the above-mentioned grate, and the corresponding buckle of design on the housing only needs during installation the grate gap portions is aimed at buckle on the housing, is in place can rotate the grate certain angle gently and can fix.
During use, the gutter of floor drain directly links to each other with vacuum pipe.When keeping vacuum in the pipeline, gutter can tightly hold diaphragm of rubber, well foul smell in the pipeline is isolated, simultaneously, also normally retaining in the housing.When the housing retaining reach a certain height, the pressure that retaining produces can back down diaphragm of rubber, and retaining can be discharged by gutter.This drainage procedure need not also not need control by external force, and the pressure differential that the gravity by water produces is finished.But reserve part retaining in the housing forms secondary seal simultaneously.
Compared with prior art, advantage of the present utility model is:
This floor drain design has grate and water strainer double medium filtration parts, has prevented that effectively pipeline is not blocked, has reduced the number of times that cleans and safeguard.
This floor drain is difficult for stopping up, can not returning water because of being directly connected on the vacuum pipe, simultaneously all the time can the reserve part retaining in the housing, and can play secondary seal and anti-foul smell effect, and can effectively prevent to dry up.
Easy to use, safeguard simple and direct.
Description of drawings
Fig. 1 is the stereogram of the utility model embodiment;
Fig. 2 is the vertical view of the utility model embodiment;
Fig. 3 is the structural representation of the utility model embodiment;
Fig. 4 is the A-A sectional drawing of Fig. 1.
The specific embodiment
Embodiment is further described the utility model below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of floor drain that is used for vacuum row guiding systems comprises grate 1, housing 2, water filter assemblies.
As shown in Figure 3, water filter assemblies comprises water strainer 3, diaphragm of rubber 5 and cover plate 4, diaphragm of rubber 5 is fastened on the water strainer 3 by attachment screw 7 by cover plate 4, water filter assemblies has been assembled the back and has been formed a seal chamber 33 above the diaphragm of rubber 5 and between the water strainer 3, and the cavity inner air pressure is a standard atmospheric pressure.
Above-mentioned water strainer 3 upper design water holes 31 are seen Fig. 4, and water hole 32 is arranged next week, between gutter 21 and the water strainer 3 hole 42 are arranged, and have formed a passage that is temporarily cut off by diaphragm of rubber 5 like this between water strainer 3 and gutter 21.
Above-mentioned gutter 21 also is provided with edge 22, can increase the contact area with diaphragm of rubber 5 like this, seals gutter 21 better.
During use, above-mentioned floor drain inserts in the vacuum pipe 9 and just can normally move.Extraneous water enters in the floor drain by the hole of grate 1, water in the floor drain can flow into housing 2 bottoms by water hole 31,32, collect in the housing 2, be attached to gutter 21 on and vacuum pipe be isolated from the outside owing to the negative pressure of vacuum pipe 9 tightly holds diaphragm of rubber 5 this moment.
Water in housing runs up to a certain degree, and the hydraulic pressure of its generation can back down diaphragm of rubber 5 and enter in the gutter 21, finishes draining.
