Abstract
The utility model relates to a kind of chimney valve of improvement, it comprises valve body and spool, and described spool is located at valve inner, is provided with taper connection limit at described valve body and spool joint, described valve body is provided with actuator, and described actuator is flexibly connected with valve body by rolling bearing.The utility model low cost of manufacture, good sealing effect, leak rate is lower than 5%.
Description
Technical field
The utility model relates to a kind of valve body, is specifically related to a kind of chimney valve body.
Background technique
Existing chimney valve, between valve body and spool, gap is larger, leak rate reaches about 20%, do not meet actual operation requirements, and adopt the cover that rolls to be connected between actuator with valve body, its friction factor is larger, so the actuator that strength is larger must be selected, which adds manufacture cost.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, provides a kind of low cost of manufacture, good sealing effect, leak rate lower than 5% the chimney valve of improvement.
Technological scheme: in order to solve the problems of the technologies described above, the chimney valve of a kind of improvement described in the utility model, it comprises valve body and spool, described spool is located at valve inner, taper connection limit is provided with at described valve body and spool joint, described valve body is provided with actuator, and described actuator is flexibly connected with valve body by rolling bearing.
The tapering of described taper connection limit and Vertical direction is between 10-20 °.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model reasonable in design, overall operation is steadily reliable, adopt the taper connection limit of 10-20 °, sealing between valve body and spool is strengthened, leak rate drops to 5% by former 20%, substantially increase service behaviour, adopt rolling bearing, decrease the friction factor between actuator and valve body, like this can the lower actuator of alternative costs, greatly reduce manufacture cost, realistic usage requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the chimney valve of a kind of improvement described in the utility model, it comprises valve body 1 and spool 2, it is inner that described spool 2 is located at valve body 1, taper connection limit 3 is provided with at described valve body 1 and spool 2 joint, described valve body 1 is provided with actuator 4, and described actuator 4 is flexibly connected with valve body 1 by rolling bearing 5; The tapering of described taper connection limit 3 and Vertical direction is between 10-20 °.The utility model reasonable in design, overall operation is steadily reliable, adopt the taper connection limit of 10-20 °, the sealing between valve body and spool is strengthened, and leak rate drops to 5% by former 20%, substantially increase service behaviour, adopt rolling bearing, decrease the friction factor between actuator and valve body, like this can the lower actuator of alternative costs, greatly reduce manufacture cost, realistic usage requirement.
The utility model provides a kind of thinking and method; the method and access of this technological scheme of specific implementation is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvements and modifications can also be made; these improvements and modifications also should be considered as protection domain of the present utility model, and all available prior art of each constituent element not clear and definite in the present embodiment is realized.
