Embodiment
Below with reference to drawings and Examples the present invention is done concrete explaination.
As shown in fig. 1, the stop valve of the high frequency infrared ray carbon sulphur analyser in the embodiments of the invention comprises valve body 1, stopper rod 2, elastic element 3, rubber sealing ring 4;
One end of valve body 1 is provided with stopper rod opening 11, and the other end is provided with power gas import 12;
Stopper rod 2 is located at stopper rod opening 11 places of valve body 1.Stopper rod 2 is provided with by end 21, elastic element and connects platform 22 and seal ring connecting end 23.Elastic element 3 one ends are connected platform 22 and link to each other with elastic element, the other end links to each other with stopper rod opening 11.The stopper rod opening 11 by end 21 turnover valve body along with stretching of elastic element 3 on the stopper rod 2.When elastic element 3 compressions, the end 21 that ends of stopper rod 2 places outside the stopper rod opening 11 of valve body 1; When elastic element 3 stretched, the end 21 that ends of stopper rod 2 placed in the stopper rod opening 11 of valve body 1;
The seal ring connecting end 23 of stopper rod 2 seals by rubber sealing ring 4 and valve body 1, and forms the cavity with an opening with valve body 1, power gas import 12, rubber seal 4.
So, the stopper rod 2 of embodiments of the invention by end 21 can be along with the flexible of elastic element 3 the stopper rod opening 11 of turnover valve body 1, carry out straight reciprocating motion and ash releasing tube is unclamped in compression.Thereby the sealing of control ash discharge pipeline and unobstructed.Valve body 1, power gas import 12, rubber seal 4 form the cavity of an opening simultaneously, power gas is by in the power gas import 12 turnover cavitys, compressing rubber seal ring 4 also impels stopper rod 2 to move, and further control the flexible of elastic element 3, thereby realize by end the compression of ash releasing tube being unclamped.
The stop valve of high frequency infrared ray carbon sulphur analyser of the present invention adopts integrated design, and is simple in structure, is convenient to install, and the sealing of system is stronger, can effectively prevent the generation of gas leak phenomenon, provides guarantee for accurately measuring.
As shown in fig. 1, in an embodiment of the present invention, by the hemisphere that is shaped as of end 21.Hemispheric shape can better compress and be unlikely to block ash releasing tube, suits to be repeatedly used.
Shown in Fig. 1, in an embodiment of the present invention, the cross section of rubber sealing ring is Y shape.The shape of Y shape has the characteristic that moment opens, moment resiles, and the rubber of opening utilizes the pressure of the power gas inwall of valve body of can better fitting, thereby reaches better tightness; Also suit simultaneously to be repeatedly used, not fragile.Make ash discharge work be carried out completely
As shown in fig. 1, in an embodiment of the present invention, elastic element is selected spring for use.Certainly, in other embodiments, can use other elastic elements yet, carry out straight reciprocating motion as long as can drive stopper rod, present embodiment is not restricted this.
Shown in Fig. 1, in an embodiment of the present invention, also be provided with jump ring 5 between elastic element 3 and the valve body 1.Also be provided with back-up ring 6 between elastic element 3 and the valve body 1.Jump ring 5 and back-up ring 6 have the effect of axial restraint.Certainly, in other embodiments, yet can not arrange or arrange the device of other same functions, present embodiment is not restricted this.
In addition, as shown in fig. 1, also be provided with adjusting nut 7 on the seal ring connecting end 23 of stopper rod 2.Also be provided with rubber band 8 between adjusting nut 7 and the rubber sealing ring 4.Adjusting nut 7 and rubber band 8 have to be regulated and the fixedly effect of rubber sealing ring 4.Certainly, in other embodiments, yet can not arrange or arrange the device of other same functions, present embodiment is not restricted this.
As shown in fig. 1, in an embodiment of the present invention, stopper rod 2 be shaped as cylindrical body, the cylindrical body that is shaped as hollow aperture of valve body 1.Certainly, in other embodiments, can be arranged to other shapes, present embodiment is not restricted this yet.
When the analysis of high frequency infrared ray carbon sulphur analyser begins, power gas enters by power gas import 12, the rubber sealing ring 4 that is connected with seal ring connecting end on the stopper rod 2 opens rapidly under the pressure of power gas, and the inwall that is attached to valve body tightly, and air-flow is intercepted on rubber sealing ring 4.The pressure that power gas produces forces simultaneously with stopper rod 2 and descends, be connected the elastic element 3 compression decline rapidly that platform connects with elastic element on the stopper rod 2, what make stopper rod 2 bottoms compresses the ash releasing tube that passes stopper rod 2 bottoms by end 21 in moment, reaches the purpose of system sealing; After analyzing end, the power air valve is closed, and unpowered gas feeds valve body 1, and elastic element 3 returns to original state again, and rubber sealing ring 4 also recovers former state in moment, and ash releasing tube becomes unobstructed state immediately, and tail gas and dust are discharged to outside the system rapidly.
More than specific embodiments of the invention are described in detail, but it is as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that this practicality is carried out and substituting also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of doing under the spirit and scope of the present invention, all should contain within the scope of the invention.
