Preferably, two closing means include spring groove, and limit plate and more is equipped in two spring grooves A spring, each limit plate are mounted on expansion plate on the side wall of valve body side.
Each of be preferably located in the same spring groove one end of the spring with the bottom wall of spring groove is fixed connects It connects, the other end of the spring is fixedly connected with the bottom wall of limit plate each of in the same spring groove.
Preferably, each expansion plate all extends to the side of valve body far from one end of ipsilateral limit plate and is equipped with rubber Rubber mat.
Preferably, inlet channel is collectively formed in first curved plates and the second curved plates.
Preferably, the valve body includes shaft and valve plate, is fixedly connected in the middle part of the shaft and valve plate.
Compared with the prior art, the utility model has the beneficial effects that:
1, when valve body is opened, air-flow is flowed according to direction shown in arrow in Fig. 2, to improve output power, valve body is closed When, air-flow is flowed according to direction shown in arrow in Fig. 1, can increase the air velocity and air pressure level of air inlet, so that gasoline can Preferably atomization, burning sufficiently, improve torque.
2, when valve body is closed, reaction force can be applied to rubber pad under the mutual cooperation of spring, limit plate and expansion plate, Promote the valve plate of rubber pad and valve body to be in close contact, realizes better seal.
In conclusion can be passed through when valve body is closed in this programme by the way that two closing means are arranged in the two sides of valve body Rubber pad on the cooperation control expansion plate of spring is closely contacted with the valve plate of valve body, so that it is guaranteed that valve body closure is close Feng Xing.
Detailed description of the invention

Fig. 2 be the utility model proposes the structure of state two of floating type check valve of variable intake manifold a kind of show It is intended to;
Fig. 3 be the utility model proposes the part A structure of floating type check valve of variable intake manifold a kind of put Big figure.
In figure: 1 tube body, 2 first curved plates, 3 second curved plates, 4 valve bodies, 5 baffles, 6 springs, 7 limit plates, 8 expansion plates, 9 rubber pads, 10 spring grooves.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.
In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right", The orientation or positional relationship of the instructions such as "top", "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Referring to Fig.1-3, the floating type check valve of a kind of variable intake manifold, including tube body 1, the inside installation of tube body 1 There are the first curved plates 2 and the second curved plates 3, inlet channel is collectively formed in the first curved plates 2 and the second curved plates 3, and first is curved Valve body 4 is installed, valve body 4 includes shaft and valve plate, is fixedly connected in the middle part of shaft and valve plate between plate 2 and the second curved plates 3.
For engine in high revolving speed, valve body 4 is open state (i.e. state shown in Fig. 2), and air-flow passes through arrow institute in Fig. 2 Show that direction is flowed.
First curved plates 2 are equipped with baffle 5 on the side wall of 4 one end of valve body, and the second curved plates 3 are close to 4 one end of valve body Side wall on baffle 5 is equally installed, be equipped with closing means on the side wall of two baffles 5 and valve plate opposite side.
Two closing means include spring groove 10, are equipped with limit plate 7 and multiple springs 6, position in two spring grooves 10 It is fixedly connected with the bottom wall of spring groove 10 in one end of each spring 6 in the same spring groove 10, is located at the same spring The other end of each spring 6 in slot 10 is fixedly connected with the bottom wall of limit plate 7, and each limit plate 7 is close to 4 side of valve body Expansion plate 8 is mounted on side wall, each expansion plate 8 all extends to side and the peace of valve body 4 far from one end of ipsilateral limit plate 7 Equipped with rubber pad 9.
