Abstract
The invention aims to provide a self-closing novel flap valve and aims to solve the problems that a flap valve cover is frequently not closed in place and is easily jammed in closing and opening, reset is difficult, machining processes are complex, sealing performance is poor, and the flap valve cover cannot be adjusted after a pin shaft is mounted in the prior art. The self-closing novel flap valve comprises an L-shaped connecting rod, a flap valve cover and a flap valve seat, a first relative rotation device is arranged between the lower end of the L-shaped connecting rod and the flap valve cover, a second relative rotation device is arranged between the upper end of the L-shaped connecting rod and the flap valve seat, and a sealing device is arranged between the inner surface of the flap valve cover and the flap valve seat. The self-closing novel flap valve can be applied to the field of water supply and drainage engineering.
Description
Technical field
The present invention relates to a kind of flap valve.
Background technology
Flap valve is the tail end that is installed on drainage pipe, has and prevents that outer water from pouring in down a chimney the non retern valve of function.Rely on the opening and closing that realizes door-slapping cover by the pressure reduction of the inside and outside both sides of door-slapping cover, when tidewater higher than pipe in during water level, flap valve can be closed automatically, blocks tidewater and enters pipeline, prevents that sea, river, river from pouring in down a chimney.When tidewater debarks under wind-force effect, water on the bank can flow to rivers by flap valve again.Existing flap valve often occurs that door-slapping cover is closed lightly and closes not in placely, closed easily occurs stuck phenomenon when opening, the difficulty that resets, and processing technology is complicated.And the O type circle adopting sealing, sealing performance is poor, and the closed point of rotation of opening of existing flap valve only has one, installs after bolt axle unadjustable.
Summary of the invention
The object of this invention is to provide the novel flap valve of a kind of self-closing, with solve door-slapping cover that prior art often occurs close lightly close not in place, in the time of closure and unlatching, easily there is stuck phenomenon, difficulty resets, processing technology is complicated, sealing performance is poor, uncontrollable problem after installing bolt axle.
The embodiment of the present invention provides a kind of self-closing novel flap valve, comprise L shaped connecting rod, door-slapping cover and flap valve seat, between the bottom of described L shaped connecting rod and described door-slapping cover, be provided with first-phase to tumbler, between the described upper end of stating L shaped connecting rod and described flap valve seat, be provided with second-phase to tumbler, between the inner surface of described door-slapping cover and described flap valve seat, be provided with sealing device.
Concrete, described sealing device comprises the ring packing pad that is located at described door-slapping cover inner surface, the inner surface of described door-slapping cover is also provided with the cover plate of the described ring packing pad that is fixedly clamped.
Concrete, described first-phase comprises the first rotation seat and moving block to tumbler, described the first rotation seat is located on described door-slapping cover, described moving block bolt is connected to the bottom of described L shaped connecting rod, between described moving block and described the first rotation seat, be provided with first count door bolt, the head of described first count door bolt is provided with the first cottor pin.
Concrete, described connecting rod second-phase comprises the second rotation seat to tumbler, described the second rotation seat is located on described flap valve seat, between described the second rotation seat and the upper end of described L shaped connecting rod, is provided with second count door bolt, and the head of described second count door bolt is provided with the second cottor pin.
The novel flap valve of a kind of self-closing that the embodiment of the present invention provides, can regulate tumbler tumbler and second-phase easily by first-phase, has effectively avoided stuck generation, and adopts ring packing pad, and sealing performance improves greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the novel flap valve of a kind of self-closing that provides of the embodiment of the present invention;
Fig. 2 is the lateral view of Fig. 1;
Fig. 3 is that A-A in Fig. 1 is to sectional view;

The specific embodiment
Existing flap valve often occurs that door-slapping cover is closed lightly and closes not in placely, closed easily occurs stuck phenomenon when opening, the difficulty that resets, and processing technology is complicated.And the O type circle adopting sealing, sealing performance is poor, and the closed point of rotation of opening of existing flap valve only has one, installs after bolt axle unadjustable.
As depicted in figs. 1 and 2, the novel flap valve of self-closing, comprise L shaped connecting rod 1, door-slapping cover 2 and flap valve seat 3, between the bottom of described L shaped connecting rod 1 and described door-slapping cover 2, be provided with first-phase to tumbler, between the described upper end of stating L shaped connecting rod 1 and described flap valve seat 3, be provided with second-phase to tumbler, between the inner surface of described door-slapping cover 2 and described flap valve seat 3, be provided with sealing device.Described sealing device comprises the ring packing pad 4 that is located at described door-slapping cover 2 inner surfaces, and the inner surface of described door-slapping cover 2 is also provided with the cover plate 5 of the described ring packing pad 4 that is fixedly clamped.
As shown in Figure 4, described first-phase comprises the first rotation seat 6 and moving block 7 to tumbler, described the first rotation seat 6 is located on described door-slapping cover 2, described moving block 7 bolts are connected to the bottom of described L shaped connecting rod 1, between described moving block 7 and described the first rotation seat 6, be provided with first count door bolt 8, the head of described first count door bolt 8 is provided with the first cottor pin 9.
As shown in Figure 3, described connecting rod second-phase comprises the second rotation seat 10 to tumbler, described the second rotation seat 10 is located on described flap valve seat 3, between described the second rotation seat 10 and the upper end of described L shaped connecting rod 1, be provided with second count door bolt 11, the head of described second count door bolt 11 is provided with the second cottor pin 12.
By first-phase, to tumbler and second-phase, to tumbler, can regulate easily, can change easily and regulate, effectively avoid stuck generation, and adopt ring packing pad, sealing performance improves greatly.
Comprise the above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
