Abstract
The utility model belongs to the technical field of valves, and discloses a replaceable non-return water drain apparatus, which is mainly technically characterized in that the replaceable non-return water drain apparatus comprises a valve body with a barrel-shaped valve spool inside, the end of the valve spool is equipped with a non-return valve, the inner wall of the valve body is equipped with threads, a valve spool lock nut is connected with the threads, the top end of the valve body is equipped with a filter screen and a circular valve cover, the outer edge of the valve cover is equipped with a connecting ring, and the non-return valve is a ball valve with a support. After the replaceable non-return water drain apparatus is fixed, the connecting ring is taken off from the valve cover, and the valve cover does not contact with a concrete cement-lining again, thereby bringing more convenience for taking off the valve cover to repair the valve spool. The non-return valve is the ball valve with a support, the opening and the closing of the ball valve are completely automatically adjusted, when pressure at two ends of a water inlet and pressure at two ends of a water outlet are balanced, the ball valve can be closed by aid of self-gravitation, thereby being favorable for maintaining underground water level. Further, the replaceable non-return water drain apparatus is simple in structure and convenient in use.
Description
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of replaceable reverse-stop type hydathode.
Background technique
The reverse-stop type hydathode is specially adapted for hydraulic engineerings such as the channel, wet pit under the phreatic high situation, its objective is and subdue seepage pressure and the floating holder influence of underground water, reach thickness, the assurance structural safety of reducing investment outlay that reduces liner structure and improve the structure purpose in working life liner structure.The patent No. is that 200820005515.0 utility model patent discloses a kind of reverse-stop type hydathode, the structure of this reverse-stop type hydathode comprises the valve body that is built-in with the tubular spool, the spool end is provided with the check dodge gate, the inwall of valve body is provided with screw thread, the screwed annulus of outer wall screws in and wherein constitutes tubular spool locking framework, and the top of valve body is provided with filter screen and valve cover.Because therefore the valve body of this reverse-stop type hydathode and spool, can keep in repair and remove under the situation of not destroying the concrete cement liner structure for dividing body structure spool.But because valve cover is regular hexagon, after being fixed on the reverse-stop type hydathode in the concrete cement lining cutting, if cumbersome when wanting to take off valve cover maintenance spool.In addition, also complex structure of the check dodge gate of this reverse-stop type hydathode.
The model utility content
The technical problems to be solved in the utility model provides that a kind of valve cover takes off conveniently, replaceable reverse-stop type hydathode simple in structure.
For addressing the above problem, the technical solution adopted in the utility model is: comprise the valve body that is built-in with the tubular spool, the spool end is provided with check valve, the inwall of valve body is provided with screw thread, the spool locknut is attached thereto and connects, the top of valve body is provided with filter screen and valve cover, and described valve cover is circular, and the outer of valve cover is provided with connecting ring.
Its additional technical feature is: described check valve is the ball valve that has support; Screw thread on the described valve interior wall is a disconnecting type; The lower end of described valve body is provided with the fixing seal dish; Described fixing seal dish is a cascade.
Replaceable reverse-stop type hydathode provided by the utility model compared with prior art has the following advantages: one, valve cover are circular, and the outer of valve cover is provided with connecting ring.Like this, be fixed on the reverse-stop type hydathode in the concrete cement lining cutting after, connecting ring by taking off on the valve cover, is not had between valve cover and the concrete cement lining again and gets in touch, if very convenient when wanting to take off valve cover and keeping in repair spool; Its two, check valve is the ball valve that has support, the open and close of ball valve is regulated fully automatically, when the pressure at water intake and water outlet two ends reaches balance, rely on self gravitation can be in closed condition, help the maintenance of level of ground water, and it is simple in structure, easy to use; Its three, the screw thread on the valve interior wall is a disconnecting type, is taking off the spool locknut and valve cover time ratio is easier to; Its four, the lower end of valve body is provided with the fixing seal dish, can so that reverse-stop type hydathode and concrete cement lining contact tight, good airproof performance.And the fixing seal dish is a cascade, and then positive and negative use goes for the concrete cement lining of different heights.
Description of drawings
Fig. 1 is the package assembly schematic representation of replaceable reverse-stop type hydathode;
Fig. 2 is the structural representation of valve cover;
Fig. 3 is the structural representation of valve body.
Embodiment
Be described in further detail below in conjunction with the structure and the use principle of accompanying drawing replaceable reverse-stop type hydathode provided by the utility model.
As shown in Figure 1, replaceable reverse-stop type hydathode provided by the utility model comprises valve body 1, valve body 1 is built-in with tubular spool 2, spool 2 has guard 3, spool 2 ends be provided with have support 4 ball valve 5 as check valve, spool locknut 6 is connected with valve body 1, and the top of valve body 1 is provided with filter screen 8 and the valve cover 9 that has fixing frame 7, and the lower end of valve body 1 is provided with cascade fixing seal dish 10.As shown in Figure 2, valve cover 9 is circular, and the outer of valve cover 9 is provided with connecting ring 11.As shown in Figure 3, the screw thread 12 on valve body 1 inwall is a disconnecting type.
During use, be fixed on the reverse-stop type hydathode in the concrete cement lining cutting after, connecting ring 11 by taking off on the valve cover 9, is not had between valve cover 9 and the concrete cement lining again and gets in touch, if very convenient when wanting to take off valve cover 9 and keeping in repair spools 2.And the ball valve 5 that has support 4 is as check valve, and the open and close of ball valve 5 is regulated fully automatically, when the pressure at water intake and water outlet two ends reaches balance, rely on self gravitation can be in closed condition, help the maintenance of level of ground water, and simple in structure, easy to use.Screw thread 12 on valve body 1 inwall is a disconnecting type, is taking off spool locknut 6 and valve cover 9 time ratio is easier to.The lower end of valve body 1 is provided with fixing seal dish 10, can be so that the reverse-stop type hydathode contacts closely good airproof performance with the concrete cement lining.And fixing seal dish 10 is a cascade, and then positive and negative use goes for the concrete cement lining of different heights.
