【Specific embodiment】
The three-dimensional view of seal assembly 1 that one embodiment of the invention provides from different perspectives is shown with reference to figure 1a to 1b.
The seal assembly 1 includes first shell 2.1 and second shell 2.2.In present embodiment, the first shell 2.1 and the second shell
Spherical section shape of the body 2.2 for two identical sizes.It is in 90 degree between the first shell 2.1 and second shell 2.2.
The first shell 2.1 includes the first shell surface 2.1a outside, which includes the second shell outside
Body surface face 2.2a.The first shell 2.1 includes the outlet portion 3 of a circulation, which includes an outlet portion 4 being closed.
In present embodiment, the opening portion 3 of the circulation is a circular recessed portion, is flowed through for supplied gas.
The seal assembly 1 further includes two and is used to support the seal assembly 1 in the side bearing part 6 in valve 8.Each
Include a bearing pin 5 on bearing part 6 and open up a groove 7.In present embodiment, which is circular cross section.The sealing
Component 1 is rotatably supported at by two bearing pins 5 inside the valve 8.If the seal assembly 1 is revolved by bearing pin 5
A closed position is gone to, in the closed position, which interrupts gas in a gas flow 10 (with reference to figure 3a, 3b)
Flowing, so as to achieve the effect that closure valve 8.If the seal assembly 1 is rotated by 90 degrees by bearing pin 5 so that this is close
Sealing assembly 1 is in an open position, and in the open position, which is on the gas flow 10 so that the gas
Gas in runner 10 can pass through, so as to achieve the effect that open valve 8.
Fig. 1 b show seal assembly provided by one embodiment of the present invention in the stereoscopic schematic diagram of second angle.Relative to
Seal assembly 1 in Fig. 1 a, Fig. 1 b is rotated by 90 degree.The closure outlet portion 4 be a baffle (with reference to figure 2a), the flow outlets
Portion 3 is a circular through hole.Two bearing parts 6 are set to the both sides of first shell 2.1 and second shell 2.2, and between the two
The both sides of the seal assembly 1 are relatively arranged on, so that two bearing pins 5 are towards the outside of seal assembly 1, to reach
Far from the effect inside seal assembly 1.
It is the seal assembly 1 shown with different view with reference to figure 2a to 2d.In fig. 2 a, the first shell of the seal assembly 1
Body 2.1 and its flow outlets portion 3 are shown in left side.In figure 2b, which is rotated by 90 degree, the second shell 2.2
And its it is closed outlet portion 4 and is shown in right side.In figure 2 c, which is shown in top, meanwhile, the flow-through opening portion 3
It is shown in left front.In figure 2d, on the right side of the opening portion 3 of the first shell 2.1 and its circulation is shown in, and the second shell
2.2 and its be closed opening portion 4 be shown in bottom.Meanwhile as can be seen that being wrapped on the 2.1a of the first shell surface from Fig. 2 a-2d
A border circular areas 2.1b for surrounding the flow-through opening portion 3 is included, includes one and first shell surface on the 2.2a of the second shell surface
The corresponding border circular areas 2.2b of border circular areas on 2.1a.On border circular areas 2.1b and second shell in first shell 2.1
Border circular areas 2.2b corresponding with border circular areas 2.1b is also shown simultaneously.Border circular areas 2.1b and border circular areas 2.2b
Size it is identical, such first shell and second shell can well be sealed with sealing ring 11.In present embodiment
In, both border circular areas 2.1b and border circular areas 2.2b are overlapped at least part.The first shell surface
The border circular areas of 2.1a and the curvature of the border circular areas on the 2.2a of second shell surface are identical.Due to the first shell surface
2.1a is identical with shape, the curvature of second shell surface 2.2a, thus by seal assembly 1 and sealing ring 11 (with reference to figure 3a,
Combination 3b) can carry out better seal when valve 8 (with reference to figure 3a, 3b) is in gas circulation and interrupt status, avoid
Gas flows out.In present embodiment, the sealing ring 11 is lip-type packing 11.
Valve 8 as shown in figs. 3 a and 3b.In fig. 3 a, which is in opening state, in fig 3b, at the valve 8
In closed state.The valve 8 includes a valve closed cell 9.Based on the position of the valve closed cell 9, the gas is negotiable
As shown in Figure 3a or it is interrupted as shown in Figure 3b.If the valve closed cell 9 is parallel with gas flow 10 by positioning,
The valve 8 is in opening state, whereas if the seal assembly 1 and its valve closed cell 9 are rotated by 90 degrees so that the valve
Closed cell 9 is vertical with gas flow 10, then the valve 8 is closed, and gas circulation is interrupted.
Further, which further includes position of the driving unit 13 for control valve 8.Present embodiment
In, which includes a motor.
Seal assembly 1 as shown in Figure 4 includes first shell 2.1 upward and the second shell for being set to rear
2.2.The seal assembly 1 includes a series of additional reinforcing ribs 12 being set in first shell and second shell.The additional reinforcement
Muscle 12 is used to strengthen or increase the intensity of first shell and second shell.In present embodiment, which can pass through note
Modeling technological forming is made.
The schematic diagram of seal assembly 1 as shown in Figure 5, the first shell 2.1, the flow-through opening portion 3 and first shell
Top is located in around the border circular areas 2.1b in flow-through opening portion 3 on 2.1, meanwhile, the second shell 2.2, closure opening
Border circular areas 2.2b corresponding with the border circular areas 2.1b in first shell is located in left side in portion 4 and second shell 2.2.
For those of ordinary skill in the art, without departing from the inventive concept of the premise, if can also make
Dry modification and improvement, these belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended right
Subject to it is required that.
