Description
Technical field
The utility model relates to and belongs to valve technology field, and underground water is eliminated to the osmotic pressure of liner structure and the flap valve formula water trap of floating holder influence in especially a kind of canal slope that is used for.
Background technology
In present remote Inter-Basin Water Transfer Project or large-scale irrigation district, in order to reduce investment outlay, water delivery, water distribution system adopt the channel of trapezoidal cross-section mostly, in order to reduce the canal seepage amount, often adopt concrete that channel is carried out full section lining cutting.In the higher canal section of groundwater table, groundwater table is higher than at the bottom of the canal, often makes underground water row less than in the channel because of the anti-seepage of channels, make it to produce bigger uplift pressure, the canal lining stringcourse is risen, destroy canal lining, therefore for guaranteeing canal lining safety, channel draining depressurized system must be set; At present, measure commonly used is that drain hole is set on liner structure, and underground water freely is communicated with complementary with surface water.When underground water level was lower than in the canal face of land water level, this conventional way had following drawback: the one, and channel water can permeate the ground continuously by drain hole, causes a large amount of water bodys wastes; The 2nd, because water body permeates the ground in a large number, easily cause the ground seepage failure, particularly in the zones that easily subsides such as underground goafs, can cause secondary geological disaster; The 3rd, along with the following of water oozes, deposit in the canal one now can be brought into undergroundly, stop up basic infiltration capillary channel and drain hole, cause drain function to lose efficacy, influence structural safety.
In order to address the above problem, the patent No. is that the Chinese patent of ZL200820005515.0 discloses a kind of inverse-stopping type water trap, this inverse-stopping type water trap comprises that inwall is provided with the valve body of the integral structure of fixed part, the tubular spool that has the annular wing limit of mating with described valve body snaps in wherein, this spool end is provided with the check dodge gate, the inwall of valve body is provided with screw thread, and the screwed annulus of outside wall surface screws in the valve body tubular spool is compressed locking.Above-mentioned inverse-stopping type water trap can be implemented in 360 ° the interior direction of adjusting the check dodge gate arbitrarily of scope when mounted, makes the movable axis of check dodge gate be in the position of top, makes things convenient for its opening and closing.
Though having solved groundwater table to a certain extent, above-mentioned inverse-stopping type water trap is lower than the problem that canal oozes under the channel water when low, but, the projected life of described inverse-stopping type water trap is generally about 10 years, and be at least 50 years the application life of hydraulic engineering concrete lining structure, therefore the spool that need change water trap in the course of work of hydraulic engineering guarantees the quality and the life-span of hydraulic engineering, in the replacing process, the staff wears diving dress operation under water, in the replacing process, unloading annulus could take out spool, and the spool of above-mentioned inverse-stopping type water trap cooperates screw-in to compress by a screwed annulus of outside wall surface with valve body, therefore the staff needs under water annulus to be screwed out in the replacing process, so big leap ahead the underwater time of staying of staff, increased the danger of changing spool, simultaneously, because water trap is under water for a long time, its surperficial smoother, this has increased difficulty also for the replacing to spool.
Summary of the invention

For achieving the above object, the utility model adopts following technical scheme: flap valve formula water trap, comprise spool and valve body with water inlet pipe and outlet pipe, described spool comprises spool locking device, flap valve seat and is articulated in flap valve on the flap valve seat that described flap valve seat is fixed in the valve body by the spool locking device by its endoporus.
Described flap valve seat is a loop configuration, and described spool locking device is provided with can be by the through hole of flap valve sealing, and an end of spool locking device is provided with the limit wing that is used to compress the flap valve seat.
Described spool locking device is threaded with valve body, and the end that the spool locking device is provided with the limit wing is provided with instrument and clamps mouth.
Described spool locking device is provided with the card key, and the spool locking device is connected on the valve body.
Described spool locking device water outlet side is provided with the sealing ring of sealing when being used to realize spool locking device and check dodge gate closure.
Be pressed with sealing ring between described spool locking device and the flap valve seat.
Be pressed with sealing ring between described flap valve seat and the valve body.
The water outlet side of described valve body is provided with filtering cover.
The outer adhesive pad that circumferentially is provided with of described valve body.
The water inlet end of described water inlet pipe is bolted with adjustable tube connector, and adjustable tube connector is set to taper closing in structure away from an end of water inlet pipe.
Spool of the present utility model is made of movable flap valve of check and spool locking device, by the spool locking device the movable flap valve of check is fixed in the valve body, does not need to install fixed spool by other again, has simplified the structure of inverse-stopping type water trap; The spool locking device is threaded with valve body, reduced the length of threaded engagement in the installation process, make the installation and removal of spool more fast, simultaneously on the spool locking device, instrument is set and clamps mouth, avoided giving and installed and change the inconvenience that causes because of spool locking device smooth surface; The spool locking device cooperates with valve body with the form of clamping, can make the installation and removal of spool more quick, the sealing when spool locking device water outlet side is provided with sealing ring and can guarantees that spool locking device and check dodge gate are closed; Be pressed with sealing ring between described spool locking device and the flap valve seat, guaranteed the sealing of spool locking device and flap valve seat cooperation place; Be pressed with sealing ring between flap valve seat and the valve body, can guarantee the sealing between flap valve seat and the valve body; The water outlet side of valve body is provided with filtering cover, has prevented that floating thing is deposited in obstruction valve body in the valve body in the channel; The outer adhesive pad that circumferentially is provided with of valve body has guaranteed that valve body contacts closely with the concrete lining course, improves sealing; The water inlet end of water inlet pipe is bolted with adjustable tube connector, and the height of the regulation valve body that can manually make progress makes the outer end of valve body concordant with the lining cutting laminar surface.
