The utility model is achieved by following technological scheme:
A kind of positive/negative-pressure seal water system, comprises water sealed tank body, internal partition, inner gas phase connecting tube, emptying interpolation pipe, technique gas port, drain, flow-off, drain and water supplement port; Described water sealed tank body is divided into upper chamber and lower chambers by internal partition, and upper chamber is connected by described inner gas phase connecting tube with lower chambers; Described technique gas port is positioned at above water sealed tank body, and is connected with storage tank by storage tank gas phase pipeline; Described upper chamber and lower chambers respectively arrange a drain, are connected with air respectively by emptying interpolation pipe; Described water supplement port is arranged on upper chamber top; Described flow-off is arranged on lower chamber top; Described drain has two, is separately positioned on upper chamber and lower chambers bottom side;
Further, the quantity of described technique gas port is 1, and under being provided with and extending to water sealed tank body interior liquid level by emptying interpolation pipe; The quantity of described flow-off is 1; The quantity of described water supplement port is 1;
Further, described upper chamber and lower chambers are respectively arranged with this stereoscope, to observe liquid level situation in water seal;
Further, described positive/negative-pressure seal water system environmentally temperature can arrange necessary heat tracing insulating system;
Further, described flow-off connects separately the discharge opeing of skirt line or shares the discharge opeing of same skirt line with described drain;
Further, the drain that described upper chamber and lower chambers are arranged respectively connects blow-down pipe respectively by emptying interpolation pipe and is connected with air, or shared same blow-down pipe is connected with air.
The beneficial effects of the utility model are:
(1), the utility model only adopts a water sealed tank body to realize malleation water seal and negative-pressure water-sealing two kinds of functions, the occupation of land of the equipment of minimizing simultaneously.
(2), the utility model only has a technique gas port, a flow-off and a water supplement port, the complexity of the outside pipe arrangement of minimizing, reduces the length of outside pipe arrangement and the quantity of related valve and pipe fitting.
(3), the utility model decreases the Flange joint quantity of apparatus body, the risk that the equipment of reduction is revealed.
(4), the utility model structure is simple, is easy to operation and maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. water sealed tank body; 2. this stereoscope; 3. internal partition; 4. inner gas phase connecting tube, 5. emptying interpolation pipe; 6. technique gas port; 7. drain; 8. flow-off; 9. drain; 10. water supplement port; 11. heat tracing insulating systems.
Embodiment
As shown in Figure 1, the utility model discloses a kind of positive/negative-pressure seal water system, comprise water sealed tank body 1, this stereoscope 2, internal partition 3, inner gas phase connecting tube 4, emptying interpolation pipe 5, technique gas port 6, drain 7, flow-off 8, drain 9, water supplement port 10 and heat tracing insulating system 11.Wherein connect inner upper and lower two chambers of water seal inner gas phase connecting tube 4; Technique gas port 6 is connected with storage tank; Drain 7 is connected with air.
Storage tank gas phase pipeline is only connected with a technique gas port 6 of positive/negative-pressure seal water system, and technique gas port 6 is provided with and extends interpolation pipe under water sealed tank body interior liquid level.Positive/negative-pressure seal water system is only provided with a flow-off 8 and a water supplement port 10, and its upper and lower chamber respectively arranges a drain 7.Flow-off 8 can connect separately the discharge opeing of skirt line, also can share the discharge opeing of same skirt line with drain 9; Drain 7 can connect separately skirt line and be connected with air, also can share same blow-down pipe.Positive/negative-pressure seal water system respectively arranges this stereoscope 2 in upper chamber and lower chambers, to observe liquid level situation in seal water system, positive/negative-pressure seal water system also environmentally temperature can arrange necessary heat tracing insulating system 11 simultaneously.
Using process of the present utility model is: first from water supplement port 10 to water filling water seal during use, the water filling situation of water seal upper chamber can be observed by this stereoscope of upper chamber 2, after upper chamber fills water, water flows into lower chambers by inner gas phase connecting tube 4, until hypocavate be full of water after water flow out from flow-off 8, the water filling situation of hypocavate can be observed from this stereoscope of hypocavate.Now set up stable liquid level in water seal, then connected technique gas port 6 and water seal is connected with system gas, positive/negative-pressure water seal is come into operation.If ambient temperature is lower, heat tracing insulating system 11 can be come into operation, ensure that the water in water seal can not freeze.When positive/negative-pressure water seal is stopped using, first close technique gas port 6 and water seal and system are disconnected, then open drain 9 and the water in water seal is put only.
