Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, present embodiments provide a kind of low-pressure drainage system, this low-pressure drainage system mainly includes dredge pump 1, vacuum pump 4, vacuum tank 2, vacuum water tank 5, the parts such as vacuum valve 6 and vacuum collector 8, further, the PLC control system for controlling vacuum valve is also included in the present embodiment, the import of dredge pump connects vacuum tank bottom, blowdown delivery side of pump connects sewage disposal system or city planting ductwork by pipeline, vacuum pump connects vacuum tank and vacuum water tank, vacuum tank connects vacuum valve and vacuum collector by vacuum pipe 9, its course of work is as follows: vacuum arrives vacuum valve by vacuum line, the switch of vacuum valve is controlled by control system, the sewage of vacuum collector is drawn onto in the vacuum tank of vacuum station, when sewage in vacuum tank arrives after certain liquid level, dredge pump automatically starts sewage is discharged to city planting ductwork or sewage disposal system.
In the present embodiment, be also provided with the balance pipe 3 for being communicated with dredge pump 1 and vacuum tank 2 in the exit of dredge pump.There is no this in prior art to arrange, just must overcome the pressure differential between import and outlet when which results in dredge pump work, not only operating noise is comparatively large, and adds energy consumption, shortens application life.Balance pipe is communicated with dredge pump outlet and vacuum tank, makes pressure balance therebetween, namely makes dredge pump operationally, without the need to overcoming the pressure differential between import and outlet, reducing operating noise and energy consumption, extending the application life of pump.
As shown in Figure 2, the present embodiment adopts bivalve to control, namely after vacuum collector, be equipped with two vacuum valves, the vacuum valve structure that the present embodiment adopts is as follows: vacuum valve is vacuum diaphragm valve, this vacuum diaphragm valve comprises valve seat, be connected with valve seat and form the valve gap of valve body with valve seat, valve seat is provided with import and outlet, on the bottom of valve seat and import and outlet between be provided with base stalk, and with base obstruct be flexibly connected and obstruct closed cut-off equipment in its natural state with base, the outer of cut-off equipment is connected with valve seat, valve body is divided into upper and lower two parts, wherein lower part is the fluid passage of liquid communication.Further, cut-off equipment comprises and obstructs with base closed in its natural state, and make the trapped convex rubber diaphragm in fluid passage and be located at the rib of convex surface of convex rubber diaphragm, convex rubber diaphragm is connected with valve seat with the outer of rib.Further, down, concave surface is installed in valve body the convex surface of convex rubber diaphragm upward.This vacuum valve utilizes the elastic force of special rubber diaphragm self to realize first time sealing (due to special rubber diaphragm and suitable deformation stroke, cancel the spring above rubber diaphragm, rubber diaphragm deformation degree of freedom is unrestricted, not only simple valve body structure further increases the stability in use procedure), then the rib of rubber diaphragm convex surface sucked to obstruct at the base of valve seat by pull of vacuum and carry out secondary seal; When startup working programme, negative pressure of vacuum picks up rubber diaphragm to connect the pipe-line system of vacuum, when the program of quitting work, rubber diaphragm drops on the base stalk of valve seat by the dynamics of convex shape down naturally, to block the pipe-line system of vacuum, thus realize the program of the Push And Release of vacuum diaphragm valve.Owing to decreasing in valve the unfavorable factor using spring, and use bivalve, so the stability of whole system is strengthened.
The present embodiment adopts the opening and closing of PLC control system to vacuum valve to control, its for existing control system unlike: by the quantity of PLC control system setting vacuum collector work, before setting value does not reach requirement, all the other vacuum collector do not participate in work, as: setting can only use by 4-6 vacuum collector simultaneously, after this 4-6 vacuum collector exhausts, carry out next step action again.By above-mentioned setting, there is the phenomenon of taking out not to the utmost in the system that avoids, thus adds the stability of a system because of multiple vacuum collector.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on above-mentioned design principle; for solving same technical problem; even if some making on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
