Description

A kind of drainage means

Technical field

The utility model relates to a kind of drainage means, is particularly useful for using on the reaction turbine.

Background technique

Aborning, often liquid to be discharged in the container of lower from the container of eminence, but owing to have convex parts to cut off between two containers, can't realize the gravity flow of liquid, at this moment, the method that people usually adopt is to utilize pump etc. that liquid is taken out toward lower from eminence, for example, reaction turbine is in operation, in order to solve water Oil Guide basin ponding problem, generally adopt the mode of head cover drainage pump drainage at present, so not only waste electric energy, and pump is fragile, and maintenance is inconvenient.

The model utility content

The purpose of this utility model provides a kind of drainage means that utilizes siphon principle to realize unpowered automatic drain, and energy saving is easy to maintenance.

Another purpose of the present utility model is to realize automatic drain when fluid accumulation arrives to a certain degree.

For achieving the above object, drainage means of the present utility model comprises the bending water pipe, than the other end height, at the high-end one-way valve that is equipped with of water pipe, at the low side of water pipe valve is installed in the position of user mode sewer one end.

Above-mentioned drainage means has the filler in the design of the eminence of water pipe.

Above-mentioned drainage means is installed a valvular end at water pipe solenoid valve is installed, and solenoid valve is connected with the buoy electric switch.

Above-mentioned drainage means, its buoy electric switch comprises: main body, the fixed contact of fixing on main body can be connected with buoyancy aid in the lower end of slide bar along the slide bar of main body slide relative, is fixed with the moving contact supporting with fixed contact on slide bar.

Above-mentioned drainage means, fixed contact fixing on main body is upper and lower two pairs, moving contact can move between these two pairs of fixed contacts, article three, circuit parallel connection, wherein article one circuit is in series with normally open contact and solenoid relay valve, the second circuit comprises the relay of connect again after upper static contact and the normally open contact parallel connection normally closed interlock and control normally open contact, and the 3rd circuit is in series with down fixed contact and controls the relay of normally closed interlock.

Above-mentioned drainage means also is connected with the control switch with third gear position on article one circuit.

Because the utility model water pipe is bending, the end that one-way valve is installed is a water intake, be seated in the higher container, it is drain opening that a valvular end is installed, thereby the position of water intake is higher than drain opening, and according to siphon principle, water can enter from the water intake of water pipe, discharge from drain opening, realize the purpose of unpowered draining; Owing to one-way valve is installed at water intake, in drain opening valve is installed, when not needing draining, with valve closing, the water in the water pipe will be stored in the water pipe, reduce when needing draining once more the trouble of can diversion in water pipe; Owing to solenoid valve is installed in drain opening, this solenoid valve is controlled by the buoy electric switch, and the buoy electric switch is to control by the liquid water level of putting in the water pipe water intake container, when the fluid accumulation in putting the water intake container arrives to a certain degree; buoy electric switch control electromagnetic valve, realize automatic drain.Owing to cancelled pump, make the utility model simple in structure simultaneously, long service life, easy to maintenance, saving power.

Description of drawings

Figure 1 shows that the cross-sectional schematic when the utility model is used for reaction turbine.

Fig. 2 is control circuit figure shown in Figure 1.

Embodiment

As shown in the figure, water pipe (10) is the U type, its water intake is seated in the water Oil Guide basin (1), one-way valve (13) is installed on this water intake, valve (12) and solenoid valve (11) are installed on the water outlet, also design has filler (9) and lid (8) on water pipe (10), in water Oil Guide basin (1), the buoy electric switch is installed also, this buoy electric switch comprises tubular type main body (4), on main body (4), be fixed with upper static contact (6) and following fixed contact (5), one slide bar that can slide (3) is arranged in main body (4), on slide bar (3), be fixed with moving contact (7), moving contact (7) moves with moving between upper static contact (6) and following fixed contact (5) of slide bar (3), be fixed with buoyancy aid (2) in the lower end of slide bar (3), this buoyancy aid (2) can be a ball float, also can make with the other materials lighter than water; Between solenoid valve (11) and buoy electric switch, connect by control circuit, control circuit comprises the circuit of three parallel connections, as shown in Figure 2, article one, circuit is control switch (14), normally open contact (15) and relay (16) series connection, control switch (14) has the third gear position, wherein a gear is put with normally open contact (15) and is connected, realize automatically, second gear is only put and is connected with relay (16), realize that manually, the third gear position disconnects normally open contact (15) and relay (16) circuit, realizes stopping; The second circuit is that upper static contact (6) is connected with normally closed interlock (19) and relay (17) with normally open contact (20) back in parallel; Article three, circuit is that fixed contact (5) is connected with relay (18) down.Normally open contact (15) and (20) are by relay (17) control, and normally closed interlock (19) is controlled by relay (18).Working procedure is: open valve (12), control switch (14) is seated in automatic transmission, when the ponding in the water Oil Guide basin (1) acquires a certain degree, buoyancy aid (2) rises, promoting slide bar (3) rises, moving contact (7) on the slide bar (3) is contacted with upper static contact (6), electric current is by upper static contact (6), normally closed interlock (19) and relay (17) form the loop, relay (17) work, normally open contact (15) and (20) closure, on the one hand, electric current is by control switch (14), normally open contact (15) and relay (16) form the loop, relay (16) work is opened solenoid valve, and water pipe (10) is according to the outside draining of siphon principle; On the other hand, electromagnetism is by normally open contact (20), normally closed interlock (19) and relay (17) form the loop, when reducing gradually when the water in the water Oil Guide basin (1) because by water pipe (10) discharging, buoyancy aid (2) descends, moving contact (7) breaks away from upper static contact (6), but this moment is because normally open contact (20) is closed, make water pipe (10) continue draining, water in water Oil Guide basin (1) continues to reduce, moving contact (7) and following fixed contact (5) be when contacting, and electric current is by fixed contact (5) down, relay (18) forms the loop, relay (18) work, normally closed interlock (19) is disconnected, relay (17) quits work, and normally open contact (15) and (20) disconnect, and relay (16) quits work, the valve of solenoid valve (11) is closed under the effect of spring automatically, and water pipe (10) stops draining.
