Abstract

The invention provides a combined sealing floor drain, which comprises a floor drain main body, a floor drain cover, a check valve and a trap. The floor drain is characterized in that the check valve and the trap both are independent components, the floor drain main body is internally provided with two or more check valves and traps, and the combined seal is performed by using mechanical seal of the check valve and/or a dodge gate and/or water seal of the traps. The combined sealing floor drain has the advantages of rapid switch, good sealing effect, small flow resistance, large displacement, strong self-cleaning capacity, good return-proof performance and the like.

Description

A kind of combined sealing floor drain

Technical field

The present invention relates to a kind of floor drain, especially a kind of combined sealing floor drain.

Background technology

Existing floor drain mainly is divided into two kinds of water-seal floor drain and mechanical seal floor drains, and the floor drain kind that has water seal and mechanical seal simultaneously seldom.The existing ubiquitous problem of floor drain mainly is: 1. the water seal height of most of water-seal floor drain is not enough, and majority has only 10-30mm, and is very easily dry; The sealing effectiveness of mechanical seal floor drain is relatively poor, often loses sealing function because of mechanical breakdown or foreign material attach; 2. the deep water feud drainability of leaking a little less than, be prone to the phenomenon of impeded drainage; 3. the self-purification ability of floor drain is poor, tangles hair, settled sludge easily, forms to stop up, and need often clear up.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, good sealing effect, big, strong, the non-maintaining combined sealing floor drain of self-cleaning ability of water-flowing amount.

Combined sealing floor drain of the present invention mainly is made up of drain cover, floor drain body, one way valve and trap.Drain cover is installed in the top of floor drain body, and one way valve and trap are independently parts, and one way valve and trap are installed in the inside or the bottom of floor drain body successively.The water inlet of one way valve matches with the water inlet of floor drain body, be generally circle, one way valve side direction center below water inlet is contracted to an end of outfall, the position of respective side below more also is contracted to the other end of outfall to the center, a valve is installed at the outfall place, one end of valve has rotating shaft, rotates by the rotating shaft fastening devices that is arranged on the check valve body, and valve utilizes the gravity of self that delivery port is sealed; The plane at valve place and the central axis of one way valve have an angle α, and its angle is the 0-90 degree, is advisable with the 5-10 degree.The water inlet of trap also is circular, and to opposite side, the bottom that makes trap is a hemispherical to the side below water inlet by arc transition; The opposite side of water inlet below is shrunk to a plane to the center and inserts in the hemisphere, thereby forms water seal; The water seal height of trap is 0-50mm, is advisable with 5-10mm.For strengthening the sealing performance of floor drain, at the delivery port place of trap one dodge gate can be installed, dodge gate rotates by the rotating shaft that is installed in the inboard place of delivery port, utilizes the gravity of self that delivery port is sealed.The bottom of floor drain body is the pipe of long delivery port undergauge, and trap and one way valve are packed in the pipe successively, and the delivery port undergauge of pipe helps forming siphon drainage, increases the drainability of floor drain.The bottom of floor drain body also can be adopted short pipe or do not had pipe, and one way valve is directly installed on the trap inner upper end of increasing, and trap is installed on the floor drain body again, can reduce the shared height of floor drain when being applied in the Homofloor drainage system.One way valve and trap should be installed in opposite directions, and promptly its delivery port is beneficial to reduce the height of floor drain in the both sides of correspondence; So not only can reduce cost, and help application in Homofloor drainage system.Trap can be replaced by one way valve, and two one way valves that promptly are installed in series in the floor drain body to improve the drainability and the self-cleaning ability of floor drain, are applicable to the occasion that displacement is bigger.The quantity of one way valve or trap can continue to increase, its quantity is many more, the sealing performance of floor drain is good more, promptly, in the floor drain body two or more one way valves and trap can be installed, that is the quantity sum of floor drain body internal check valve and trap is more than or equal to 2 according to different needs.

The invention has the beneficial effects as follows that combined sealing floor drain has advantages such as switch is rapid, displacement big, good sealing effect, resistance to water-flow is little, the self-cleaning ability is strong, simple in structure, easy to use, need not safeguard.In addition, owing to have mechanical seal, so floor drain also has good overflow-proof performance.

Fig. 1 is the structural representation of embodiment 1.

Fig. 2 is the structural representation of embodiment 2.

Fig. 3 is the structural representation of embodiment 3.

Among the figure: 1. floor drain body, 2. drain cover, 3. one way valve, 4 traps, 5. dodge gate.

The specific embodiment

Embodiment 1

With reference to figure 1, combined sealing floor drain is made up of floor drain body 1, drain cover 2, one way valve 3, trap 4 and dodge gate 5.Drain cover 2 is arranged at the top of floor drain body 1, and the lower end is the pipe of an outlet undergauge, and one way valve 3 and trap 4 are installed in the pipe of floor drain body 1 lower end, and dodge gate 5 is installed in the delivery port place of trap 4.The course of work of combined sealing floor drain is as follows: current enter in floor drain body 1 and the one way valve 3 by drain cover 2, the valve open of one way valve 3 under the gravity of current and momentum effect, and the angle of big more its unlatching of current is also big more; Current accumulate in the trap 4 after by one way valve 3, and current are washed the undergauge delivery port of dodge gate 5 by floor drain body 1 open and entered in the sewer after the water seal of trap 4 is full of.After current stopped, one way valve 3 and dodge gate 5 were closed thereupon, and the water in the trap 4 no longer flows out, and formed water seal; If long-time anhydrous the entering of floor drain, the water seal of one way valve 3 and dodge gate 5 formed twice mechanical seals and middle trap 4 still exists, and floor drain still is in sealing state completely.

Embodiment 2

With reference to figure 2, combined sealing floor drain is made up of floor drain body 1, drain cover 2 and one way valve 3.Drain cover 2 is arranged at the top of floor drain body 1, and the lower end is a pipe, and one way valve 3 has two, is installed in series in the pipe of floor drain body 1 lower end.Compare with embodiment 1, trap is replaced by one way valve, more helps increasing the displacement and the self-cleaning ability of floor drain, is suitable for the big occasion of displacement.

Embodiment 3

With reference to figure 3, combined sealing floor drain is made up of floor drain body 1, drain cover 2, one way valve 3 and trap 4.Drain cover 2 is arranged at the top of floor drain body 1, and one way valve 3 is installed in the trap 4, and trap 4 is installed in the lower end of floor drain body 1.Compare with embodiment 1, floor drain body 1 lower end does not have the exit of pipe, trap 4 not have dodge gate, not only can reduce the cost and the height of floor drain, and helps increasing the displacement and the self-cleaning ability of floor drain.
