Abstract
The invention provides a pipe burst self-closing valve, and belongs to the technical field of city water supply pipe network safety. The pipe burst self-closing valve can effectively solve the valve self-closing problem after pipe burst. The pipe burst self-closing valve comprises an upper valve body and a lower valve body. A valve deck is arranged on the top of the upper valve body with a water outlet, and the valve deck is of a through structure with steps. One end of a switch lever with a reset spring is connected with the valve deck, and a buckle is arranged at the other end of the switch lever. A water inlet is connected with the lower valve body through a straight joint, and a hydraulic cylinder which is parallel to the water inlet is arranged in the middle of the lower valve body. A buckle is arranged at the front end of a piston rod. The hydraulic cylinder is fixedly connected with the lower valve body through a connecting piece. A liquid inlet of the hydraulic cylinder is connected with the water inlet through a hose. A flange piece with a hole is arranged between the upper valve body and the lower valve body. The pipe burst self-closing valve is mainly used in a city water supply pipe network.
Description
Technical field
The invention belongs to public supply mains security technology area, particularly a kind of technology of booster automatic-closing valve.
Background technique
Water supply network is important urban infrastructure, and its system is huge, external interference factor is many, and pipeline own material quality and installation quality differ greatly.This makes water supply network pipe explosion accident of common occurrence.Water supply network pipe explosion accident not only damages water work, and can cause large-scale waterflooding, and impact is produced and life, thrusts highway, affects public transport, cause huge economic loss.And after running water pipe occurs, often there is the maintenance Kong Chuan district of a long duration.Therefore we devise this booster water valve and solve this problem.
From present Research both domestic and external, mainly for the detecting method of tap water pipe network control centre for whole region pipe network, and also very few for the research of emergency action method after running water pipe booster.There is now the patent of a lot of research Self-closed water valve, mostly also can realize the function of water-cut off self-closure, but these water valves often also exist some defects.A wherein maximum defect is that most self closing stop valves is back down spool to realize by hydraulic pressure the function that water valve is opened under service position, the maximum deficiency of this design is that the size of hydraulic pressure is usually unstable, sometimes the continuous motion of spool can be caused to make flow instability due to the fluctuation of hydraulic pressure, in addition because the athletic meeting that spool is long-term makes spring failure, and water valve is caused to lose efficacy.As the self closing stop valve designed by Chinese patent CN94230689, be just the use of this structure.
In addition, the structure of some Self-closed water valves is too complicated, and as China Patent No. CN201310701044, this invention is realizing employing four motions in self-closing whole process, and we know, the structure of machinery is complicated, and often rate of fault is higher.This invention also exists the not quick detachable shortcoming with assembling of structure in the design in addition, and any breaks down, and will not easily discharge.
Summary of the invention
The object of this invention is to provide a kind of self-closing valve for tube bursting door, it can solve the automatic closing problem of booster late gate effectively.
The object of the invention is to be achieved through the following technical solutions: a kind of self-closing valve for tube bursting door, comprise upper valve body and lower valve body, the top being provided with the upper valve body of water outlet is provided with valve gap, valve gap is the communicating structure with step, the one end being provided with the switch lever of Returnning spring is connected with valve gap, and the other end is provided with buckle; Water intake is by being directly connected with lower valve body, the oil hydraulic cylinder parallel with water intake is provided with in the middle part of lower valve body, the front end of piston rod is provided with buckle, oil hydraulic cylinder is fixed by link and lower valve body, the liquid entering hole of oil hydraulic cylinder is connected with water intake by flexible pipe, is provided with flange plate with holes between upper valve body and lower valve body.
Described buckle is fixed on switch lever lower end, and its top is provided with gasket seal.
Returnning spring is provided with in described oil hydraulic cylinder.
Described buckle is provided with O RunddichtringO.
Working principle:
Under normal operation, current enter valve body from water intake, and produce pressure by the flexible pipe be connected with water intake to oil hydraulic cylinder, Hydraulic Cylinder buckle enters valve body, now presses switch, buckle and buckle) be mutually engaged, form self-locking, the osculum be now positioned on flange plate is unimpeded.
Once generation booster, the rapid drawdown of tap water pipe network hydraulic pressure, oil hydraulic cylinder decompression, under the effect of oil hydraulic cylinder Returnning spring, oil hydraulic cylinder resets, buckle is retracted, buckle self-locking was lost efficacy, and be positioned at the action of reset spring below switch, buckle is retracted with switch lever, sealing gasket compresses the osculum be positioned on flange plate, water valve cuts out, even if now have current in water pipe, also cannot pass through water valve.
Process accordingly, make use of pressure reduction before and after booster and achieves self-closing function.
Compared with prior art, the invention has the beneficial effects as follows:
One. employ buckle structure innovatively, realize Logic judgment by mechanical structure, upper some comparing market adopt the product of control circui more reliable, and rate of fault is lower.
Two. make use of the energy difference before and after tap water pipe burst, do not need extra power, energy saving
Three. solve running water pipe booster and keep in repair the empty window phase and reach water resource waste
Working principle:
Under normal operation, current enter valve body from water intake, and produce pressure by the flexible pipe be connected with water intake to oil hydraulic cylinder, Hydraulic Cylinder buckle enters valve body, now presses switch, and buckle is engaged mutually with buckle, form self-locking, the osculum be now positioned on flange plate is unimpeded.
Once generation booster, the rapid drawdown of tap water pipe network hydraulic pressure, oil hydraulic cylinder decompression, under the effect of oil hydraulic cylinder Returnning spring, oil hydraulic cylinder resets, buckle is retracted, buckle self-locking was lost efficacy, and be positioned at the action of reset spring below switch, buckle is retracted with switch lever, sealing gasket compresses the osculum be positioned on flange plate, water valve cuts out, even if now have current in water pipe, also cannot pass through water valve.
Process accordingly, make use of pressure reduction before and after booster and achieves self-closing function.
