Abstract
The utility model discloses a vacuum interlocking gear is prevented in preliminary treatment, including activated carbon filter, secondary filter and high -pressure pump, activated carbon filter, secondary filter and high -pressure pump are connected in proper order, the last vacuum break valve that installs of activated carbon filter, install low -voltage protective switch between secondary filter and the high -pressure pump. The utility model discloses a vacuum interlocking gear is prevented in preliminary treatment has increased behind the vacuum break valve and hou mian low -voltage protective switch formation dual fail -safe effect, does benefit to the operation of equipment safety and stability more.
Description
Technical field
The utility model relates to pre-treatment anti-vacuum interlocking mechanism technical field, the anti-vacuum interlocking mechanism of specifically a kind of pre-treatment.
Background technology
Due in equipment running process, low-voltage protective switch is improper owing to regulating, or in long wet environment, pressure switch is failure to actuate because of corrosion.Extremely easily because to cut off the water above or water yield supply is not gone up, high-pressure pump cannot be stopped, and causes strainer above to inhale flat damage.
Utility model content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, solves the technological deficiency existed at present, the utility model discloses the anti-vacuum interlocking mechanism of a kind of pre-treatment.
The technical scheme that the utility model adopts is:
The anti-vacuum interlocking mechanism of pre-treatment; comprise activated charcoal filter, secondary filter and high-pressure pump; described activated charcoal filter, secondary filter and high-pressure pump are linked in sequence, and described activated charcoal filter is provided with vacuum breaker valve, are provided with low-voltage protective switch between described secondary filter and high-pressure pump.
The beneficial effects of the utility model are,
The anti-vacuum interlocking mechanism of a kind of pre-treatment disclosed in the utility model, after adding vacuum breaker valve, and low-voltage protective switch below forms double insurance effect, is more beneficial to device security steady running.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-vacuum interlocking mechanism of the utility model pre-treatment.
In figure, 1, activated charcoal filter 2, secondary filter 3, high-pressure pump 4, vacuum breaker valve 5, low-voltage protective switch.
Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1; the anti-vacuum interlocking mechanism of pre-treatment; comprise activated charcoal filter, secondary filter and high-pressure pump; described activated charcoal filter, secondary filter and high-pressure pump are linked in sequence; described activated charcoal filter is provided with vacuum breaker valve, between described secondary filter and high-pressure pump, low-voltage protective switch is installed.
The anti-vacuum interlocking mechanism of pre-treatment disclosed in the utility model, by add vacuum breaker valve on activated charcoal filter after, and low-voltage protective switch below forms double insurance effect, is more beneficial to device security steady running.
Be noted that, the above embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendments made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
