Description
Technical field
The utility model relates to plumbing valve field, particularly relates to a kind of sewage exhaust valve protective gear.
Background technique
China's domestic sewage and industrial wastewater need long distance pressure to be delivered to sewage treatment works.In course of conveying, the gas that the gas that impeller sucks, microorganism produce, if do not discharged in time, can cause that carrying capacity declines, pipeline causes damage because pressure is excessive.Therefore sewage network all installs outlet valve additional for the gas discharging in pipeline, guarantees the pressure balance in pipeline.
Existing composite exhaust valve is installed on the place of likely high speed intake and exhaust, air during water-filling in high speed purging line, sucks air and keeps draining unobstructed, constantly can get rid of the air of precipitation when pipeline normally works when pipeline emptying.
The outlet valve that the current blow-off line of China is installed mostly is the composite exhaust valve of SCAR type; as China Patent Publication No.: a kind of Combined sewage exhaust valve disclosed in 202946747U; because sewage collecting is uneven in using; startup-shutdown is frequent; pipeline pressure is unbalanced; add impurity in sewage more, exhaust valve float ball driving mechanism often blocks, slow movement, ageing of rubber, impurity is bonded at the first-class phenomenon of rubber ring, cause outlet valve to produce leakage phenomenon.The generation of fault can cause the security incident of environmental pollution, and social repercussion is larger.And erection unit under inspection shaft can not be realized to be immersed in water and the differentiation of water inlet and water outlet under rainy day two kinds of environment, no matter be therefore that sewage leaks or the blowdown of normal rainwater, also will also can trigger signal cause reporting by mistake.
Model utility content
The utility model, in order to solve prior art problem, designs a kind of sewage exhaust valve protective gear that can prevent sewage network exhaust valve leaks and wrong report.
The technical solution of the utility model is: a kind of sewage exhaust valve protective gear, the shell being provided with protective gear is coordinated at the cap locations of composite exhaust valve, upper shed is closed by rubber seal and top cover, and there is position shelf the upper shed position of shell, position shelf bottom is connected to ball float by movable rod, movable rod can touch through the guide rod in position shelf in the moving upward of ball float, the end that guide rod stretches out position shelf bottom is provided with rubber stopper, the arc seal ring with rubber seal interference fit is had in the middle part of guide rod, arc seal ring can touch the mechanical switch valve be arranged in top cover, the base of shell and top cover are provided with pressure transducer to be respectively used to detect the pressure in composite exhaust valve and protective gear.
Preferred as one, there are the impeller for detecting flow direction or electromagnetic flowmeter in position shelf.
Preferred as one, top cover there are solar panels.
In sum, the beneficial effects of the utility model are:
After composite exhaust valve leaks; sewage flows in protective gear; movable rod is up pushed away by ball float; arc seal ring is impelled to touch mechanical switch valve; and make the read value of the pressure transducer detected in composite exhaust valve equal with the value of the pressure transducer detecting pressure in protective gear; now arc seal ring covers rubber seal completely, solves secondary pollution problem.The force value of two pressure transducers can be coordinated in addition, judge total state of leaking, thus solve the problem revealed and report by mistake.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of embodiment of the utility model.
Embodiment
As shown in Figure 1: a kind of sewage exhaust valve protective gear; composite exhaust valve 1 is conventional SCAR type; after removing original cover plate, coordinate at the cap locations of composite exhaust valve 1 shell 20 being provided with protective gear 2, and the relief opening of composite exhaust valve is communicated with protective gear 2.The upper shed of shell is closed by rubber seal 26 and top cover 3, and there is position shelf 23 the upper shed position of shell 20, position shelf 23 bottom is connected to ball float 21 by movable rod 22, movable rod 22 can touch through the guide rod 27 in position shelf 23 in the moving upward of ball float 21, the end that guide rod 27 stretches out position shelf 23 bottom is provided with rubber stopper 28, have the arc seal ring 24 with described rubber seal 26 interference fit in the middle part of guide rod 27, arc seal ring 24 can touch the mechanical switch valve 29 be arranged in top cover 3.Like this, original composite exhaust valve is defined as one-level outlet valve, substitutes the protective gear of original cover plate as secondary exhaust valve.The base of shell 20 and top cover are separately installed with pressure transducer 30 and 31 to be respectively used to detect the pressure in composite exhaust valve and protective gear.
The operation of the anti-leak considered during design and bio-occlusion draining is as follows:
1) when leaking; arc seal ring 24 touches the direction of action from lower to upper of mechanical switch valve 29, and judges that current are by the interior abnormal direction outbound flowed in conjunction with whether the pressure transducer 30 on SCAR outlet valve is equal with the pressure transducer 31 in protective gear.
2) when rain or inspection shaft in store up the bio-occlusion drainage situation of full water under, arc seal ring 24 touches the basipetal direction of action of mechanical switch valve 29 to judge that current are from the outer bio-occlusion draining toward interior stream, in addition in the composite exhaust valve 1 closedown situation of pipe interior draining, protective gear 2 is opened as secondary exhaust valve, and time protective gear is soaked to inspection shaft and the rainwater of rainy day, when hydraulic pressure in protective gear is equal with external water pressure, in order to prevent the wrong report of secondary protection device, judge whether composite exhaust valve normally closes by pressure transducer 30.
3) hydraulic pressure to compare point below two kinds of situations judge:
A. bio-occlusion draining time; when composite exhaust valve 1 is as one-level exhaust valve closure, when protective gear 2 is opened as secondary exhaust valve, one-level outlet valve pressure transducer pressure 30 is very large; secondary exhaust valve pressure transducer 31 pressure is little, thinks bio-occlusion draining.B., when the value that pressure transducer 30 and 31 records is equal, exhaust gas leakage is thought.
In order to better auxiliary pressure sensor in the present embodiment, realization erection unit under inspection shaft is immersed in the differentiation with water inlet under rainy day two kinds of environment and water outlet in water, judgement is that sewage leaks or the blowdown of normal rainwater, has the impeller for detecting flow direction or electromagnetic flowmeter in position shelf.Solar panels 5 are equipped with when the timing of employing Electromagnetic Flow, the block 4 of top cover 3, providing for electric energy.
After composite exhaust valve 1 leaks; sewage is collected in the protective gear 2 designed by embodiment; along with the continuity of time; movable rod 22 is up pushed away by buoyancy of water effect by ball float 21; arc seal ring 24 is impelled to touch mechanical switch valve; and make the read value of the pressure transducer 30 detected in composite exhaust valve equal with the value of the pressure transducer 31 detecting pressure in protective gear 2; now arc seal ring 24 covers rubber seal 26 completely, solves secondary pollution problem.The force value of two pressure transducers can be coordinated in addition, judge total state of leaking, thus solve the problem revealed and report by mistake.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
