Abstract
The utility model discloses a backhoe draining check valve of seepage controlling canal, inside a tube-shaped valve body a combined valve core with a water purifier is positioned through screw thread; the outer end of the combined valve core is a tube holder with a block shoulder, another end of the tube holder is provided with a valve core base through screw thread fit, a drain screw hole is positioned at the center of the valve core base and connects the drain pipe of water purifier, a valve core tube whose outer diameter is less than inner diameter of the tube holder positioned at the upper valve core base and an internal screw is positioned inside the upper end of the valve core tube, drain holes are arranged evenly on the lower side for the tube wall of the valve core tube, a control valve controlled by a stopper spring is positioned inside the valve core tube and matches the joint face of the base of the valve core base. The utility model can not only meet the seepage controlling function of the seepage controlling canal, but also can drain seepage water below the bottom plate of the canal in time and improve stability of the seepage controlling canal and prolong the period of usage. The utility model has the advantages of reasonable structure designing, durability in use, convenient maintenance, reliable running and high sensibility.
Description
Technical field
The utility model belongs to the solution anti-seepage channel and discharges reverse osmosis water under the plate, prolongs the anti-seepage channel device, particularly anti-seepage channel reverse drainage check valve in working life.
Background technique
In the last few years, the building anti-seepage channel generally all adopted concrete slab, and the back side of the concrete slab of installing on channel is being provided with antiseepage film and bed course.Its barrier performance is good, easy construction, and cost is lower.But concrete slab can antiseepage can discharge again that the problem of seepage water never is well solved under the plate.When anti-seepage channel stops water delivery, percolating water between antiseepage film and bed course can not in time be discharged, reverse osmosis water will take place and concrete slab occur by the floating holder of reverse osmosis water in canal base plate and bank protection, cause channel to destroy, because the percolating water between antiseepage film and bed course can not in time be discharged, occur canal base plate and bank protection in the winter time by frost heave, and make the destroyed problem of anti-seepage channel.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-seepage channel reverse drainage check valve, anti-seepage channel reverse drainage check valve is installed on the channel bottom panel, not only can satisfy the antiseepage function of anti-seepage channel, and can also in time discharge the percolating water of canal base plate bottom, can improve the steadiness of anti-seepage channel and increase the service life.
The purpose of this utility model is achieved in that a kind of anti-seepage channel reverse drainage check valve, the combination valve core that has water filter is installed by being threaded in tubular valve body, combination valve core is the base that the outer end has shoulder block, by the cooperation that is threaded valve core case is installed in the base of its other end, the base center of valve core case has the draining screw, the waste pipe of water filter is connected on the draining screw of base, the valve core tube of external diameter less than the base internal diameter is being set on the top of valve core case base, in the valve core tube upper pipes, internal thread is being set, the uniform weep hole that is being provided with on the downside tube wall of valve core tube, the spool of limit spring control is installed in valve core tube, and spool matches with the mating face of valve core case base.
When on the canal base plate of anti-seepage channel, the utility model being installed; on the canal base plate, punch; insert certain thickness mung bean stone in the extending bore that below the hole, digs; put into check valve; again mung bean stone is inserted under the base plate along annular gap; after closely twining the polyamine ester asbestos rope between canal base plate and the check valve case, put into the jointing of Kong Zhongyong concrete mortar, protective cover is installed, can cross water after solidifying fully on the top of check valve.The effect of water pressure of the operation current in the anti-seepage channel closes check valve on the end face of spool, guarantees that anti-seepage channel normally uses, and guarantees the antiseepage function of anti-seepage channel.After anti-seepage channel was cut off the water, the percolating water of canal base plate bottom entered combination valve core behind water purifier filtration, and the hydraulic pressure of percolating water backs down spool, make percolating water in time be discharged to the canal base plate above.Because the utility model can in time discharge the percolating water of canal base plate bottom, thereby effectively prevented to make canal base plate and bank protection produce floating holder destruction and winter by the problem of frost heave because the percolating water that canal base plate bottom exists produces reverse osmosis.Improve the steadiness of anti-seepage channel and prolonged working life.The utility model is simple and reasonable, and is durable in use, easy to maintenance, reliable, highly sensitive.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a sectional structure schematic representation of the present utility model.
Embodiment
A kind of anti-seepage channel reverse drainage check valve, as shown in drawings, the combination valve core that has water filter is installed by being threaded in tubular valve body 1, combination valve core is the base 2 that the outer end has shoulder block, by the cooperation that is threaded valve core case 3 is installed in the base 2 of its other end, the base center of valve core case 3 has the draining screw, and the waste pipe of water filter is connected on the draining screw of valve core case 3 bases.Between the shoulder block surface of contact of tubular valve body 1 exterior edge face and combination valve core, seal ring 7 is installed.Water filter is in the filter core support 10 of cylindrical cage shape filter core 11 to be installed, and on the center hole of filter core support 10 base plates screwed waste pipe is being set.Water filter can filtering enters the water quality in the valve body 1, the sensitivity and the working life of having improved check valve.The valve core tube 4 of external diameter less than base 2 internal diameters is being set on the top of valve core case 3 bases, in valve core tube 4 upper pipes, internal thread is being set, the uniform weep hole 8 that is being provided with on the downside tube wall of valve core tube 4, the spool 9 of limit spring 5 controls is installed in valve core tube 4, and spool 9 matches with the mating face of valve core case 3 bases.By screw thread gland 6 is installed in valve core tube 4 upper pipes, gland 6 is with limit spring 5 location.Filter screen 12 is installed on the external port of base 2, filters, prevent that the utility model from stopping up, and improves working life for entering water of the present utility model from base 2 external port.
