Abstract

The utility model relates to a sewage check valve comprising a valve body (1), a rocker (2), a valve flap (3) and a rocker cushioning device (4), wherein a through cavity is formed on the valve body (1); one end of the rocker (2) is arranged on the inner wall of the valve body (1) in a rotating way; the valve flap (3) is arranged at the other end of the rocker (2), and the opening or closing of the through cavity can be realized along with the rotation of the rocker (2); the rocker cushioning device (4) is arranged on the part of the rocker (2) in contact with the inner wall of the valve body (1) after the valve flap (3) is opened; a filtering device is arranged at the position of a water inlet of the valve body (1); a dirt taking-out opening (5) is arranged on the outer side wall of the valve body (1) and is located at the dirt intercepting end of the filtering device; and a closed door capable of being opened is arranged on dirt taking-out opening (5). The sewage check valve not only can prevent failure of the check function due to dirt accumulation at the position of the valve flap, but also is convenient for dirt taking-out.

Description

Wastewater stopping valve

Technical field

The utility model relates to a kind of safety check, specifically, is a kind of wastewater stopping valve.

Background technique

Safety check claims one-way valve or check valve again, is that open-shut device is opened or closed to a kind of strength by media flow voluntarily, with the valve that prevents that medium from flowing backwards.Chinese patent literature CN201273387Y has proposed a kind of safety check rocking bar and safety check, the end of rocking bar is provided with damping device, safety check includes valve body, flap, rocking bar, described rocking bar is connected with flap, and the front end of rocking bar is connected with the valve body of safety check by bearing pin, and described safety check inside is provided with the damping device of avoiding rocking bar and valve body direct collision.This damping device comprises that afterbody forms the T type elastomer block of tapped hole, T type elastomer block is installed in bolt on the rocking bar, and is enclosed within on the T type elastomer block, the spring that the compressive strain of T type elastomer block is resetted.But the prior art is used for sewage conduct, also there is following shortcoming when preventing sewage backflow: be mingled with a large amount of impurity dirts in the sewage, when the obstruction of the flap that meets safety check, a part is deposited in the flap place easily, after these impurity dirt accumulation are more and more, the flap place of safety check can not close tight again, thereby causes sewage backflow, the effect forfeiture of safety check; The impurity dirt that is deposited in the flap place in addition also is inconvenient to draw out.

The model utility content

For this reason, when technical problem to be solved in the utility model was that safety check of the prior art is used for sewage conduct, the flap place can pile up the impurity dirt and cause the problem of safety check effect forfeiture, and a kind of wastewater stopping valve that is suitable on the sewage conduct is provided.

For solving the problems of the technologies described above, a kind of wastewater stopping valve of the present utility model comprises

Valve body forms cavity on the described valve body;

Rocking bar, an end of described rocking bar is arranged on the inwall of described valve body rotationally;

Flap, described flap are arranged on the other end of described rocking bar, by realizing the unlatching of described cavity with the rotation of described rocking bar or closing;

After rocking bar buffering device, described rocking bar buffering device are arranged on described flap unlatching, the position that contacts with described valve interior wall on the described rocking bar;

The water inlet of described valve body is provided with filtrating equipment, also is provided with the dirt conveying end on the described outer side of valve body, and described dirt conveying end is arranged on the dirt interception end of described filtrating equipment, and also is provided with openable seal door on the described dirt conveying end.

Described wastewater stopping valve, described filtrating equipment are filter screen.

Described wastewater stopping valve, described seal door are door made of tempered glass.

Technique scheme of the present utility model has the following advantages compared to existing technology, and 1, in the utility model, the setting of the water inlet filtrating equipment of valve body can either be blocked in the water inlet with dirt, and it is indoor to prevent that also mouse from climbing into by sewage conduct; The setting of dirt conveying end and door made of tempered glass can be observed the situation that dirt impurity is piled up in the safety check, thereby clears up in real time.

Description of drawings

For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below

Fig. 1 is the sectional view of wastewater stopping valve of the present utility model.

Reference character is expressed as among the figure: 1-valve body, 2-rocking bar, 3-flap, 4-rocking bar buffering device, 5-dirt conveying end, 6-filter screen, 7-door made of tempered glass.

Embodiment

As shown in Figure 1, a kind of wastewater stopping valve of present embodiment comprises

Valve body 1 forms cavity on the described valve body 1;

Rocking bar 2, an end of described rocking bar 2 is arranged on the inwall of described valve body 1 rotationally;

Flap 3, described flap 3 is arranged on the other end of described rocking bar 2, by realizing the unlatching of described cavity with the rotation of described rocking bar 2 or closing;

After rocking bar buffering device 4, described rocking bar buffering device 4 are arranged on described flap 3 unlatchings, the position that contacts with described valve body 1 inwall on the described rocking bar 2;

In order to prevent that dirt impurity is deposited in described flap 3 places, the water inlet of described valve body 1 is provided with filtrating equipment, also be provided with dirt conveying end 5 on the outer side wall of described valve body 1, described dirt conveying end 5 is arranged on the dirt interception end of described filtrating equipment, and also is provided with openable seal door on the described dirt conveying end 5.In the present embodiment, described filtrating equipment is a filter screen 6.Described seal door is a door made of tempered glass 7.Observe the situation that dirt impurity is piled up in the safety check by door made of tempered glass, clear up in real time.

Obviously, the foregoing description only is for example clearly is described, and is not the qualification to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being extended out thus or change still are among the protection domain of the utility model creation.
