Abstract
The utility model relates to a hydraulic floating gate which is composed of a doorframe, an abutment and gates, and a buoyancy tank with a hydrovalve is fixed on the gate. The gate can also be the structure of double gates formed by an upper gate and a lower gate that can rotatablely connected with each other via a free bearing with the buoyancy tank provided with the hydrovalve fixedly installed respectively on the upper gate and the lower gate. Due to the abutment being fixed directly on the doorframe, the accuracy of the mounting position of the gate relative to the sealing device of the doorframe is guaranteed, and the tightness of sealing water is improved. The buoyancy of the upper gate and the lower gate under water is controlled independently by charging and discharging water in the buoyancy tank. So, either a suitable degree of opening is guaranteed, or the force of percussion of the gate is decreased.
Description
Technical field
The utility model relates to a kind ofly controls the waterpower control technology field that flap valve opens and closes automatically by current self kinetic energy, specifically is meant a kind of waterpower floating flap valve.
Background technology
The existing employed flap valve of hydraulic engineering, doorframe and bearing adopt pre-embedded bolt to be anchored in the reinforced concrete structure respectively, influenced by construction condition, and flap valve can't accurately be located, and antipriming is difficult to reach the sealing effectiveness of expection.The flap valve that is in tilted layout is pressed on the antipriming of doorframe by deadweight, makes its water shutoff, and from great, then open degree reduces as flap valve; Little as the flap valve deadweight, then sealing is poor.Because the flap valve that is in water is subjected to the acting in conjunction of gravity and buoyancy simultaneously, this is a pair of direction opposite effect power, the existing employed flap valve of hydraulic engineering is after making installation, the gravity that the flap valve that is in water is subjected to, buoyancy are changeless, can not regulate the difficult result of use that reaches expection according to the real work situation.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art part, provides a kind of good sealing effect, opening resistance little, can control the waterpower floating flap valve of its opening angle by regulating flap valve buoyancy.
Waterpower floating flap valve described in the utility model comprises doorframe, bearing and flap valve, it is characterized in that, fixed installation has the buoyancy tank of water valve on the described flap valve.Described flap valve can also be made up of last flap valve that is rotationally connected mutually by free bearing and following flap valve, and described going up on flap valve, the following flap valve fixedly mounts the buoyancy tank that has water valve respectively; Described flap valve is rotationally connected by bearing and the doorframe that is fixed on the doorframe.
The utility model compared with prior art has following advantage and beneficial effect:
The utility model has guaranteed the installation site precision of the antipriming on the relative doorframe of flap valve because bearing directly is fixed on the doorframe, has improved the tightness of water shutoff.The buoyancy of flap valve (or going up flap valve and following flap valve) in water carries out independent regulation by filling, discharging water of buoyancy tank, both can guarantee suitable open degree, can reduce the impact of flap valve again, can adapt to different job requirements.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment one
As shown in Figure 1, flap valve 3 and the bearing 2 that is fixed on the doorframe 1 are rotationally connected, and flap valve 3 is subjected to the acting in conjunction of buoyancy in gravity and the water, and during the low discharge duty, flap valve 3 opening angles are little; During big flow duty, flap valve 3 opening angles are big, because the buoyancy of flap valve 3 can be by the last draining valve 4 of buoyancy tank 5 and the independent regulation of filling, discharge water of following draining valve 6, so the opening angle of flap valve 3 has also obtained effective control, double dot dash line is the position of flap valve 3 when being in closed condition.
Embodiment two
As shown in Figure 2, present embodiment is the doublebeat door.Last flap valve 9 and following flap valve 8 are rotationally connected by free bearing 7, last flap valve 9 is rotationally connected with the bearing 2 that is fixed on the doorframe 1 again, and last flap valve 9 and following flap valve 8 are subjected to the acting in conjunction of buoyancy in gravity and the water, during the low discharge duty, following flap valve 8 local unlatchings, opening resistance is little; During big flow duty, last flap valve 9 and following flap valve 8 are opened simultaneously, since the buoyancy of last flap valve 9 can be by buoyancy tank 11 the independent regulation of filling, discharge water (operating principle of following flap valve 8 is identical) of last draining valve 10 and following draining valve 12, so the opening angle of last flap valve 9 and following flap valve 8 has also obtained effective control, double dot dash line is the position of last flap valve 9 when being in closed condition with following flap valve 8.
The utility model can be used for the cutout of pumping plant outlet to be controlled automatically, also can be used for the outfall of rivers,lakes and seas limit unattended hydraulic pipe, is preventing flow backwards in the draining smoothly, and it is simple in structure, uses flexible and safe and reliable.
Claims (3)
1. waterpower floating flap valve comprises doorframe, bearing and flap valve, it is characterized in that, fixed installation has the buoyancy tank of water valve on the described flap valve.
2. waterpower floating flap valve according to claim 1 is characterized in that, described flap valve is made up of last flap valve that is rotationally connected mutually by free bearing and following flap valve, and described going up on flap valve, the following flap valve fixedly mounts the buoyancy tank that has water valve respectively.
