Abstract
The utility model discloses an anti-backflow siphon apparatus, which comprises a siphon destroying device. A water inlet pipe and a breather pipe are respectively connected on the upper end of the siphon destroying device. The lower end of the siphon destroying device is connected with a water outlet pipe. The anti-backflow siphon apparatus can prevent harmful siphoning generated in the water inlet pipe on the upper end of the siphon destroying device from damaging an on-line analyzing instrument probe and further make the on-line analyzing instrument probe work in a condition with a stable flow state. The accuracy of monitoring data is thus guaranteed.
Description
Technical field
The utility model belongs to on-line analysis instrument servicing unit technical field, is specifically related to a kind of counterflow-preventing syphon device.
Background technology
The on-line analysis instrument has been widely used in the industrial water supply system.Existing on-line analysis instrument mounting means is all directly to be connected with the probe apparatus of on-line analysis instrument after arm is drawn in the service main road; this connected mode tends to affect the on-line analysis instrument and steadily works; especially when technique is stopped transport; probe place water can occur and be entered the service main by back suction, thereby cause probe effectively to be protected by water.
The industrial water supply pipeline is generally pressure pipeline.When one, normally moving due to technique, the variation of flow causes the instability of fluidised form, can cause that not only washing away of analysis meter probe is larger, also causes analysis meter probe apparatus the transmission of data error larger, can't reach effective monitoring.Two, due to the existence of pipeline and equipment potential difference factor, when process abnormality is stopped transport or is normally stopped transport, the capital causes that pressure pipeline produces negative pressure, cause the water in analysis meter device probe to be entered in pipeline by suck-back, thereby the whole or local disengaging hygrometric state of popping one's head in is exposed in air, probe is caused irreversible damage.
The utility model content
The purpose of this utility model is to provide a kind of counterflow-preventing syphon device, has solved the problem that the direct connecting water pipe of existing on-line analysis instrument easily produces siphonage and sustains damage.
The technical scheme that the utility model adopts is: counterflow-preventing syphon device, comprise the siphon destructive device, and siphon destructive device upper end connects respectively water inlet pipe and snorkel, and the lower end connects rising pipe.
Characteristics of the present utility model also are,
The siphon destructive device is cylindrical shape.
Siphon destructive device inside is provided with the current stabilization weir plate, and the current stabilization weir plate is connected on the inner bottom surface and madial wall of siphon destructive device, and the upper end of current stabilization weir plate is unsettled and be the right angle serrate.
The siphon destructive device is provided with view window.
Siphon destructive device lower end is provided with floss hole.
Water inlet pipe is provided with valve.
Water inlet pipe is provided with filtrator.
Filtrator is the Y type.
The port of snorkel is provided with filter cap.
The beneficial effects of the utility model are: the utility model counterflow-preventing syphon device not only can be afraid of to destroy harmful siphon of producing in water inlet pipe to the harm of on-line analysis instrument probe, on-line analysis instrument probe is worked under stabilization of fluidized, thereby guarantee the accuracy of Monitoring Data.

In figure, 1. floss hole, 2. view window, 3. siphon destructive device, 4. valve, 5. filtrator, 6. water inlet pipe, 7. snorkel, 8. filter cap, 9. current stabilization weir plate, 10. rising pipe.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of counterflow-preventing syphon device, as shown in Figure 1, comprises siphon destructive device 3, and siphon destructive device 3 upper ends connect respectively water inlet pipe 6 and snorkel 7, and the lower end connects rising pipe 10.Siphon destructive device 3 is cylindrical shape.Siphon destructive device 3 inside are provided with current stabilization weir plate 9, and current stabilization weir plate 9 is connected on the inner bottom surface and madial wall of siphon destructive device 3, and the upper end of current stabilization weir plate 9 is unsettled and be the right angle serrate.Siphon destructive device 3 is provided with view window 2.Siphon destructive device 3 lower ends are provided with floss hole 1.Water inlet pipe 6 is provided with valve 4.Water inlet pipe 6 is provided with filtrator 5.Filtrator 5 is the Y type.The port of snorkel 7 is provided with filter cap 8.
During installation, water inlet pipe 6 connects feedwater piping, and rising pipe 10 is connected to the probe apparatus of line analysis instrument.
When technique is normally moved, current enter siphon destructive device 3 along water inlet pipe 6 and by valve 4, filtrator 5, after current stabilization weir plate 9 deceleration buffers, most of kinetic transformation of current is static energy, and jump over current stabilization weir plate 9 right angle, upper end sawtooth and the overflow of last water flow stationary enters on-line analysis instrument probe apparatus.Adjust with 4 pairs of flow of inlet water of valve, by the head that view window 2 is observed on current stabilization weir plate 9, be advisable to be no more than current stabilization weir plate 9 upper end sawtooth drift angles.When technique is stopped transport; feedwater piping produces negative pressure; in water inlet pipe 6, current can enter feedwater piping to the opposite direction suck-back; because snorkel 7 is communicated with atmosphere always; this moment, atmosphere entered siphon destructive device 3 by snorkel 7; eliminate siphon, protected the water at on-line analysis instrument probe place can not be reversed and siphoned away.
In the process operation process, whether finder has leakage and spilling water to occur often.When finding that flow of inlet water reduces gradually, should in time dismantle the cleaning y-type filter.Whether have dirt adhere to, should in time dismantle cleaning when affecting observing effect if making regular check on view window 2.Regularly siphon destructive device 3 inside are cleared up according to the water quality situation, this moment can be with view window 2 as clean-up port use, and open floss hole 1 knob and disconnect rising pipe 10, must with soft brush or soft cloth, avoid damaging siphon destructive device 3 inner structures during cleaning.Filter cap 8 prevents that snorkel 7 from stopping up, and affects the anti-backflow siphon effect.
Like this, the harm that the utility model has just effectively avoided siphonage that probe is brought, and make the probe monitoring also more accurate.
