Description

The cloudy well internally piloted valve of rectangle

Technical field

The utility model relates to municipal renovation technique field, is specifically related to the cloudy well internally piloted valve of rectangle of the automatic opening and closing of a kind of energy.

Background technology

Municipal sewage system claims again sewage ditch, its inner sewage, rubbish etc. of being often detained, and the smell is awful, is also multiple harmful bacteria and viral breeding ground.Although be provided with well lid, but still keeping hole or the gap identical with ground, when often some manhole cover damage is not changed in time, cause dirty smelling out, harmful germ is outwards disseminated, and crisis people are healthy.Special in hot summer, a large amount of visceral-qi, foul smell come up from cloudy well, cause air pollution, welding health.Sewer is again the main place of insect mosquito Overwintering, and cloudy well head is the necessary channel that mosquito is come in and gone out, and a large amount of mosquitoes spreads disease in the middle of coming continuously people by cloudy well head, and harm people's is healthy.

Yet, also there is no at present effective cloudy well SLD, to the very important cloudy well sealing problem of health, seem not to be valued by the people.Retrieval is found, publication number is the disclosed utility model patent of CN101649648A " a kind of municipal sewage system non retern valve and municipal sewage system ", this scheme is that existing municipal sewage system is improved, and is designed to the mouth of a river under rectangle, thereby is convenient to assemble a kind of rubber check valve of rectangle.In fact, this scheme is that the skew wall that two make-ups are pressed is mutually set below rectangular rubber pipe, and sidewall is also set between two skew walls, between skew wall and sidewall, only has straight water outlet ofthe.During use, need to fix rubber check valve upper end, utilize the elastic force of skew wall to reach sealing purpose.Have current by time utilize hydraulic pressure to overcome elastic rubber, move the water to flow in cloudy well.The existing problem of this technology is: 1, rubber check valve upper end fixing after, while utilizing the elastic force of lower end skew wall and sidewall to seal, straight water outlet ofthe stretching degree is less.2, this rubber check valve upper end is difficult for arbitrarily taking off and installing after fixing, and skew wall need to have larger screen resilience otherwise the middle part of straight water outlet ofthe is difficult to seal completely.So the problem that larger screen resilience and rubber tube can not arbitrarily take off is for manually dredging and make troubles.3, the material of this rubber check valve is necessary for rubber and can not is other hard materials, for a long time cruelly leak and in air, there will be problem of aging, especially in adverse circumstances, inevitably Yin Gaowen, rainwater and corrosion and accelerated ageing, periodic replacement must increase huge cost.So this application can not effectively be implemented by long-time on a large scale.

Utility model content

The utility model provides for problems of the prior art and deficiency, provides the good rectangle of a kind of simple in structure but applicable effect cloudy well internally piloted valve.

The technical scheme in the invention for solving the technical problem is: the cloudy well internally piloted valve of a kind of rectangle, comprise a fixing rectangle column jecket and one group of rectangle Taper Pipe that can open, and rectangle Taper Pipe is sleeved on outside, rectangle column jecket lower end and both matched in clearance; Described rectangle Taper Pipe comprises left and right two symmetrical cone sheets, forms the pyramidal structure of sealing after left and right two cone sheet make-ups; Each fixes or is hinged with connecting rod the both sides, upper end of left and right two cone sheets, and the upper end of described connecting rod is hinged on the lateral wall of rectangle column jecket by bearing pin.

Obviously, two cone sheets are rely on deadweight and be together with each other, and utilize bearing pin as the fulcrum swinging, and this structure does not require that cone sheet is hard or soft, thus cone sheet can according to actual conditions select cheapness and application life longer material.Whole internally piloted valve is simple in structure, but is not easy to damage the degree of almost accomplishing maintenance-free.Two cone sheets can be flexible material, for example rubber.Also can be rigid material, the edge of rigid material arranges flexible seal layer, for example stainless steel or aluminium alloys or engineering plastics, and its edge arranges rubber weather strip.Can rectangle outer tube be set in the upper end of combination conical pipe, be distributed in each cone sheet upper end, be conducive to docking of rectangle Taper Pipe and rectangle column jecket.

Further, for increasing the adhesion between two cone sheets, can bore balance weight body is set on sheet at each.Magnetic Phase can also be set at two cone sheet edges and inhale material.

The upper end of described rectangle column jecket can arrange one deck flange, and flange has and can or fix with well head laminating.Being positioned at the bearing pin in rectangle column jecket outside, can be two shared bearing pins of cone sheet, also can a bearing pin be set respectively for two cone sheets.The resistance of two cone sheets is little, and artificial dredging is to carry out simply supporting laggard people to two cone sheets, also can be set to movable structure of installing by two cone sheets, during construction, two cone sheets is unloaded.Movable mode of installing: between connecting rod and bearing pin, or the structure of movable installation is set between connecting rod and two cone sheets, such as buckling or the structure such as latch fitting.

Above scheme also has the following advantages: the utility model is applicable to the conscientious transformation of existing cloudy well head; prevented mosquito turnover breeding; visceral-qi, foul smell have been stopped up again; and do not affect again drain function; to protecting the healthy of people, purifying city air pollution and sanitation of environment have played good social effect.

It is simple in structure, durable in use, and cost is low, can directly use the cloudy well internally piloted valve of this rectangle on the basis of former facility, and easy for installation, water inlet is remarkable from the effect of opening, water closes to the greatest extent certainly.
