Abstract

The utility model discloses a self-control valve of an inspection well. The self-control valve of the inspection well comprises a cylindrical pipe and a combined taper pipe, wherein the combined taper pipe comprises a left taper sheet and a right taper sheet which are symmetrical, the two sides of the upper end of each taper sheet are respectively and fixedly connected with a connection rod, and the upper end of each connection rod is hinged to the outer side wall of the cylindrical pipe through a pin shaft. The self-control valve of the inspection well is suitable for dedicated improvement on an existing inspection well mouth, mosquitoes are prevented from going in and out of the inspection well for reproduction, dirt air and bad smell are blocked, the drainage function is not affected, and the good social effects of protecting the good health of people, purifying urban air pollution and achieving environmental sanitation are achieved. The self-control valve of the inspection well is simple in structure, durable, low in cost and convenient to install; the self-control valve of the inspection well can be directly used on the basis of original facilities, and the effects that the self-control valve is automatically switched on when water enters the inspection well and is automatically closed when no water enters the inspection well are remarkable.

Description

Cloudy well internally piloted valve

Technical field

The utility model relates to municipal renovation technique field, is specifically related to the cloudy well internally piloted valve 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.

But, 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, its enforcement is only suitable for rectangle well head and is not suitable for circular well head.And circular well head can not only be economized on material, compared with The Small Well mouth floor space, and be beneficial to construction, be beneficial to into people or equipment for dredging and maintenance, so this scheme scope of application is narrower.2, after rubber check valve upper end is fixed, while utilizing lower end skew wall elastic shrinkage, sidewall provides restraint forces for straight water outlet ofthe, so straight water outlet ofthe stretching degree is less, impact is the water yield and lower water speed down, need to extend well head width and just can reach and the lower water yield of justifying well head equivalent.3, fixing rear being difficult for of rubber check valve upper end arbitrarily takes off and installs, 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.4, the rubber check valve time of rectangle cruelly leaks and in air, there will be problem of aging, especially in adverse circumstances, and 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, and a kind of simple in structure but good cloudy well internally piloted valve of applicable effect is provided.

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

Obviously, two cone sheets are that dependence is conducted oneself with dignity and is 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, thereby cone sheet can be selected the material of growing in cheapness and application life according to actual conditions.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 combination cylindricality outer tube be set in the upper end of combination conical pipe, be distributed in each cone sheet upper end, be conducive to combine docking of Taper Pipe and column tube.

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

The upper end of described column tube can arrange one deck flange, and flange has and can or fix with well head laminating.Being positioned at the bearing pin in column tube outside, can be two shared bearing pins of cone sheet, can be also that two cone sheets arrange respectively a bearing pin.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, for example, buckles 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, on the basis of former facility, can directly use this moon well internally piloted valve, easy for installation, and water inlet is remarkable from the effect of opening, water closes to the greatest extent certainly.
