Embodiment
At first see also Fig. 1-4, be transverse (being that along continuous straight runs is settled) according to the utility model first embodiment's counterweight type opening and closing device 10, it mainly comprises a body 1, a counterweight type open and close member 2 and a sealing cover 3.
Counterweight type open and close member 2 is installed in the body 1, and it is roughly rounded, matches with the shape of cross section with body 1.Counterweight type open and close member 2 has a balance weight body 21, a baffle plate 22, a counterweight pivot 23 and a stop flange 24.Balance weight body 21 is arranged on a projection of counterweight type open and close member 2 upper ends, and its weight is greater than baffle plate 22.The baffle plate 22 that links to each other with balance weight body 21 is the disk shape, and it matches with sealing cover 3 and plays the effect of closing or opening the fluid passage.Baffle plate 22 can adopt uniform sectional shape, but preferably adopts from balance weight body 21 wedge shape of attenuation gradually, so that its center of gravity is further shifted to balance weight body 21, thereby is more convenient for closing or opening action.Counterweight pivot 23 is installed in the counterweight pivot fixed groove 14 of body, thereby makes counterweight type open and close member 2 be installed on body 1 pivotly.Should be appreciated that,, and the pivot fixed groove is arranged on the counterweight type open and close member 2, equally counterweight type open and close member 2 can be installed on body 1 pivotly and the realization the purpose of this utility model if pivot is arranged on the body 1.As shown in Figure 4, when counterweight type open and close member 2 was shown in an open position, stop flange 24 matched with the protruding rank 13 of the stop on the body 1, used to prevent that 2 rotations of counterweight type open and close member are excessive.Should be appreciated that it also is a preferable feature of the present utility model that stop flange 24 cooperates with the stop on the protruding rank 13 of stop, does not have them can realize the purpose of this utility model equally.
During practical application, the counterweight type opening and closing device 10 according to this embodiment can be installed in the fluid line of lateral arrangement.With common horizontally-arranged waterpipe is example, and counterweight type opening and closing device 10 can be installed therein.When not having current out-of-date at ordinary times, counterweight type open and close member 2 keeps normally off under the action of gravity of balance weight body 21, can prevent that foul smell from entering from the external world.As water from import 11 when outlet 12 is flowed, counterweight type open and close member 2 is opened under flow action and is allowed water to flow through, after water flow through, counterweight type open and close member 2 fell again under action of gravity and keeps closed condition.From exporting 12 when import 11 is flowed, counterweight type open and close member 2 remains closes, and does not allow water pass through as water.Therefore, counterweight type opening and closing device 10 has formed an automatic switch device that is similar to one-way valve.
Fig. 5 and 6 is sectional views of second embodiment of the utility model counterweight type opening and closing device.The composition structure of this counterweight type opening and closing device 10A and first embodiment's counterweight type opening and closing device 10 are identical, but it settles the position of using just in time opposite with the latter.That is to say that body 1a, counterweight type open and close member 2a compare with the corresponding part of counterweight type opening and closing device 10 with sealing cover 3a, all are the installations of turning upside down.What particularly point out is that balance weight body is arranged on the lower end that counterweight type opens and closes 2a.
Second embodiment's counterweight type opening and closing device 10A can for example be used for exhaust duct.Under normal conditions, counterweight type open and close member 2a keeps normally open under the action of gravity of balance weight body, can allow waste gas to flow through from left to right.When extraneous wind was big, counterweight type open and close member 2a closed under the wind-force effect, forbade the wind-fall filling.When the abatement of wind, counterweight type open and close member 2a reopens under action of gravity and carries out exhaust.
Fig. 7 and 8 is sectional views of the 3rd embodiment of the utility model counterweight type opening and closing device.This counterweight type opening and closing device 10B is " vertical type " (promptly vertically settling).Compare with first embodiment shown in Fig. 1-4, this counterweight type opening and closing device 10B is just settling difference to some extent on the direction, and it forms structure and working principle is all identical with first embodiment's opening and closing device 10.What particularly point out is that counterweight type open and close member 2b is arranged on the below of sealing cover 3b.
The 3rd embodiment's counterweight type opening and closing device 10B can be used in the upright drainage pipe of arranging.When not having current out-of-date at ordinary times, counterweight type open and close member 2b keeps normally off under action of gravity, can prevent that foul smell from entering from the external world.When water flow through from top to bottom, counterweight type open and close member 2b opened under flow action and allows water to flow through, and after water flow through, counterweight type open and close member 2b turned under action of gravity and keeps closed condition.Fig. 9 and 10 is sectional views of the 4th embodiment of the utility model counterweight type opening and closing device.This counterweight type opening and closing device 10C also is " vertical type ".Compare with the 3rd embodiment shown in Fig. 7-8, the position that its arrangement is used just in time in contrast.That is to say that body 1c, counterweight type open and close member 2c compare with the corresponding part of counterweight type opening and closing device 10B with sealing cover 3c, all are the installations of turning upside down.What particularly point out is that counterweight type open and close member 2c is arranged on the top of sealing cover 3c.
The 4th embodiment's counterweight type opening and closing device 10C also can be used in the upright drainage pipe of arranging.When having current out-of-date at ordinary times, counterweight type open and close member 2c keeps normally open under action of gravity.When from top to down acted on counterweight type open and close member 2c, counterweight type open and close member 2c closed, and prevented that foreign matter from falling into pipeline as extra power (for example human body or other foreign matter weight).After foreign matter was removed, counterweight type open and close member 2c turned under action of gravity and keeps normally open.
Though abovely counterweight type opening and closing device of the present utility model is described in conjunction with several preferred embodiments, but should be appreciated that, be familiar with those skilled in the art and should on the basis of above disclosure, make various modification that are equal to or change.For example, the shape of body can change according to the shape of its place fluid line, and as square, ellipse etc., this moment, the shape of counterweight type open and close member and sealing cover also should be done corresponding variation.Therefore, protection domain of the present utility model is not limited to the description of specification, but should be limited by appended claims.
