The utility model has the advantages that the structure sets up rationally, and thermal -insulated radiating effect is good.
Description
Technical field
The utility model relates to a kind of butterfly valve, specifically refers to a kind of high temperature butterfly valve.
Background technique
Butterfly valve is Flap valve again, is the simple modulating valve of a kind of structure, can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.The structure of existing butterfly valve, generally comprises valve body, valve rod, dish plate, bottom etc., and valve plate rotates the function realizing body cavity and open or close under the effect of valve rod on body cavity.
Existing butterfly valve is when for high temperature fluid regulable control, and its electric actuator distance valve body is comparatively near, and the heat of fluid transmits out and is very easy to make electric actuator be in the condition of high temperature, causes electric actuator to cross cause thermal damage, therefore, is necessary to make improvements.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of vibrational power flow reasonable, the high temperature butterfly valve that heat insulation and dissipation is effective.
For achieving the above object, the technical solution of the utility model includes valve body, valve rod, butterfly plate and electric actuator, the corresponding valve rod bottom position of valve body is provided with bottom, the upper end of described valve body is provided with valve stem casing, valve body is provided with fluid passage, described butterfly plate is positioned at fluid passage and joint rotation is fixed on valve rod, described valve interior wall is provided with and seals adaptive valve seat with butterfly plate, the upper end of described valve rod is passed valve stem casing and is linked with electric actuator, the upper end of described valve stem casing is fixedly installed support, this pedestal upper end is provided with drum frame, described electric actuator is mounted on the upper end of drum frame, this drum frame includes the middle axle sleeve of the drum frame being positioned at its center, the upper end of described valve rod is passed axle sleeve in the middle of this drum frame and links with electric actuator, described drum frame jack shaft puts the radiating fin that longitudinal separation is distributed with multiple ring.
By this setting, support and drum frame is utilized the distance of the fluid passage of electric actuator and valve body to be pulled open, thus the high temperature media in minimizing fluid passage is to the heating radiation of electric actuator, in addition, drum frame jack shaft cover is provided with multiple radiating fin, the entirety cooling of drum frame can be contributed to, thus, the temperature of further reduction electric actuator, improves the stability that it runs.
Further setting is provided with packing cavity between described valve stem casing and valve rod, is provided with filler in this packing cavity, and valve stem casing is fixedly installed the Gland for closed packing cavity upper-end surface opening.This setting, improves the sealing of valve rod.
Further setting is that described valve body is provided with valve rod rotating sleeve relative to the bottom of valve rod, and described bottom closes the lower end surface being fixed on this valve rod rotating sleeve, and between this valve rod rotating sleeve and valve rod, movable sheath is provided with stainless steel sleeve.This setting, improves the flexibility that stem bottom is rotated.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 the utility model embodiment structural representation.
