Abstract
The utility model relates to a high-temperature butterfly valve, particularly a butterfly valve used for conveying high-temperature media. The utility model comprises a valve body, a valve plate arranged in the valve body, a valve rod connected with the valve plate and a driver used for driving the valve rod to move. The utility model is characterized in that the valve rod is provided with a cooling water passage, two ends of the valve body along the valve rod are symmetrically provided with a reinforcing steel frame and a supporting frame, and the supporting frame is provided with a cooling water connecting port communicated with the cooling water passage on the valve rod. A heat dissipation and cooling structure is adopted in order to lower the working temperature of the valve rod as a critical component, and thus the problem that the influence on normally opening and closing the butterfly valve due to deformed components caused by high temperature is fundamentally solved. The utility model is particularly suitable for making into the high-temperature butterfly valve having a wide caliber.
Description
Technical field
The utility model relates to the butterfly valve in a kind of pipeline feedway, particularly be a kind of high temperature butterfly valve of carrying high temperature media to use.
Background technique
In the pipeline feedway of high temperature media, owing to the reason of high temperature makes butterfly valve temperature distortion in the pipeline easily, cause that switch is ineffective very directly to lose efficacy, the sealing configuration of butterfly valve also is subjected to the influence of high temperature and very easily damages.Improvement to high temperature butterfly valve mostly is aspect the resistance to heat that improves sealing configuration at present, as Chinese patent 87203330.9 disclosed " high cryogenic seal butterfly valve ", form at interior each several part by valve body, the main shaft, butterfly plate, bearing bracket, bearing, Stuffing box and the sealing seat that are loaded in the valve body, adopted high temperature resistant or Stuffing box that the cold plasticity filler constitutes and the sealing seat that constitutes by tinsel and plastic filler by multilayer, and the filler in the Stuffing box is contacted with sealing seat, to reach high-and low-temperature resistance, sealing is reliable, the purpose of stable working.
Summary of the invention
The purpose of this utility model is intended to overcome this shortcoming of butterfly valve temperature distortion, provide a kind of high-intensity, can reduce butterfly valve self operating temperature and guarantee the high temperature butterfly valve of its high reliability.
The valve rod that high temperature butterfly valve of the present utility model comprises valve body, be located at valve plate in the valve body, join with valve plate, the driver of actuate valve stem motion, it is characterized in that on described valve rod, having cooling water passage, the two ends along valve rod of valve body are arranged with strengthens steelframe and support, is offering the cooling water connection mouth that communicates with cooling water passage on the valve rod on the support.During work the cooling water connection mouth of cooling water from the support inserted, discharge after cooling water enters valve rod valve rod is cooled off again, so the heat of valve rod is taken in circulation out of, makes it unlikely and is heated excessive and deformation takes place and influences normal operation.Be arranged on the reinforcement steelframe at two ends and the bulk strength that support has been strengthened valve body on the one hand, also strengthened simultaneously the distance between high temperature media in heat diffusion area and driver and sealing configuration and the valve, make parts such as the valve rod that is installed in wherein, sealing seat also not yielding, thereby realize the purpose of high temperature butterfly valve reliably working.
The utility model has the advantages that and adopted the radiating and cooling structure that the operating temperature of this critical component of valve rod is decreased, fundamentally solve the problem that the component distortion that causes owing to high temperature influences the normal open and close of butterfly valve, be particularly suitable for being made into bigbore high temperature butterfly valve.
Below in conjunction with drawings and Examples the utility model is done further explanation.But content of the present utility model is not limited only to this embodiment.
Description of drawings
Fig. 1 is the structural representation of present embodiment
Fig. 2 is the I portion enlarged view of Fig. 1
Embodiment
As shown in Figure 1, the formation of this high temperature butterfly valve comprises valve body 04, be located at the valve plate 05 in the valve body 04, the valve rod 11 that joins with valve plate 05, the driver 01 of actuate valve stem motion, have cooling water passage 07 on described valve rod 11, the two ends along valve rod of valve body are arranged with strengthens steelframe 03,13 and support 02,12, is offering the cooling water connection mouth 10,08 that communicates with cooling water passage 07 on the valve rod on the support 02,12.Structural relation between driver, valve body, valve plate, the valve rod is continued to use the structural type of existing butterfly valve, valve rod is except that the integral form that adopts present embodiment to disclose, also can adopt the form of common last lower valve rod, this moment cooling water path then separately by being configured to separately.
Still can offer a wind pushing hole 06 at a end of strengthening steelframe,, can blow down the dust and other impurities between valve seat and valve rod to this wind pushing hole air-supply by inlet valve body.
Claims (2)
1, a kind of high temperature butterfly valve, the valve rod that comprises valve body, is located at valve plate in the valve body, joins with valve plate, the driver of actuate valve stem motion, it is characterized in that on described valve rod, having cooling water passage, the two ends along valve rod of valve body are arranged with strengthens steelframe and support, is offering the cooling water connection mouth that communicates with cooling water passage on the valve rod on the support.
2, high temperature butterfly valve as claimed in claim 1 is characterized in that offering a wind pushing hole at the end by inlet valve body of described reinforcement steelframe.
