Description
Technical Field
This novel butterfly valve that belongs to, concretely relates to high performance butterfly valve for high humidity environment.
Background
The butterfly valve has simple structure, small volume, light weight and material consumptionChinese character shao (a Chinese character of 'shao')The valve has the advantages of small installation size, small driving moment, simple and rapid operation, good flow regulation function and closing sealing property, and is one of the fastest valve varieties developed in the last decade.
Butterfly valves are widely used. The variety and number of the valve are still continuously expanded, and the valve has a trend towards a plurality of fields such as high temperature, high pressure, large caliber, high sealing property, long service life, excellent regulation characteristic, one-valve multifunctional development and the like. In industrial system application, the reliability and other performance indexes of the system reach higher levels. The common butterfly valve is called a single eccentric butterfly valve and a central line butterfly valve, is generally used for water treatment, has the temperature and the pressure within normal ranges, and rarely has opening and closing functions. The high-performance butterfly valve is designed according to the difference of the axis, the butterfly plate and the cross section, so that the friction at the sealing surface is reduced, the service life is prolonged, and the sealing degree is improved.
However, the marine high-performance butterfly valve has a defect that: under the high humidity working condition, if the valve has the condition of multi-angle or inverted installation, the driving shaft sleeve connecting the valve rod and the actuating mechanism can cause the valve rod to be seriously rusted due to water vapor flowing backwards, the transmission capacity is influenced, the normal opening and closing movement of the valve is further influenced, and serious consequences are caused. Because the shaft sleeve has poor maintainability, long time is wasted for manual overhaul and replacement when the machine is stopped every time, and certain maintenance cost is increased from the economic aspect.
SUMMERY OF THE UTILITY MODEL
This is novel to prior art's defect, provides a high performance butterfly valve for high humidity environment.
This is novel to realize like this: the utility model provides a high performance butterfly valve for high humidity environment, wherein, includes the valve body, sets up the valve rod in the valve body, and the valve body is stretched out on the top of valve rod, and the part that stretches out the valve body at the valve rod sets up and supports seal assembly, and the tip of valve rod is connected with actuating mechanism through supporting seal assembly.
As above high performance butterfly valve for high humidity environment, wherein, support seal assembly includes the support, and the support is the disc part, sets up the through-hole that matches with the valve rod at the center of support, sets up two-layer annular groove around this through-hole, still sets up a plurality of bolt holes at the support, and the support is equipped with two journal stirrup, sets up the screw hole on the journal stirrup.
According to the high-performance butterfly valve for the high-humidity environment, the shaft sleeve is arranged above the support, and the size of the shaft sleeve is matched with that of the valve rod.
The high-performance butterfly valve for the high-humidity environment is characterized in that the sealing ring is arranged in the annular groove with the smaller size of the bracket.
The high-performance butterfly valve for the high-humidity environment is characterized in that the positioning plate is arranged in the annular groove with the larger size of the bracket.
The high-performance butterfly valve for the high-humidity environment is characterized in that the support is fixed on the valve body through the support lug and the screw.
The high-performance butterfly valve for the high-humidity environment is characterized in that the sealing gasket is arranged at the position, extending out of the valve body, of the valve rod.
This neotype effect that is showing is: the utility model has the characteristics of economy, reliability and the likeIs higherPractical value can reduce manual work and cost of maintenance after popularizing and applying, produces good economic benefits, can improve the corrosion resistance of driving shaft cover, improves the life of valve.

In the figure: 1, a valve body; 2, flange; 3, a disc plate; 4, a pin; 5, a valve rod; 6, sealing gasket; 7, bolts; 8, filling; 9, a bracket; 10, sealing rings; 11, positioning a plate; 12, bolts; 13 shaft sleeve; 14 actuator
Detailed Description
The structure is similar to the structure of a common butterfly valve as shown in figure 1, the valve main body is composed of a valve body 1 and a flange 2 which are connected by bolts 7, and a sealing gasket 6 is arranged between the valve main body and the flange to form a complete pressure boundary. The disc 3 is located inside the valve body 1 and is connected to the valve stem 5 by a pin 4. And a packing 8 is arranged between the valve body 1 and the valve rod 5 to ensure the lower part of the valve rod 5 to be sealed. A sealing ring 10 and a positioning plate 11 are arranged between the actuating mechanism 14 and the valve rod 5, so that the upper part of the valve rod 5 is sealed. The actuating mechanism 14 is connected with the support 9 through the bolt 12, the actuating mechanism 14 drives the shaft sleeve 13 to drive the valve rod 5 and the disc plate 3 to move, and the opening and closing functions of the valve are achieved.
The upper sealing of the valve rod is ensured by improving the structural design of the support, the sealing ring and the positioning plate. When water vapor flows back from the outside and enters the driving shaft sleeve, the water vapor flowing into the inside of the actuating mechanism is greatly reduced through the double sealing structure of the sealing ring and the positioning plate, and the influence on the shaft sleeve is avoided; the design of the bracket can be comprehensively manufactured by a process, and when the requirement of marine or high-humidity working conditions is met, the requirement can be met only by installing the sealing ring and the positioning plate.
The following provides a further description of the present invention.
The structure diagram of the interior of the high-performance butterfly valve execution device is shown in figure 2, compared with the structure of a common butterfly valve, the structure is mainly characterized in that two sealing concave surfaces are processed on a flange on a support, two sealing rings and a positioning plate are installed in the concave surfaces, and when water vapor in the atmosphere is poured into an actuator from a valve rod, the water vapor can be blocked by the sealing rings in contact with the valve rod; when water vapor in the air flows into the actuator from the gap between the actuator and the support, the water vapor is blocked by the sealing ring between the support and the actuator; therefore, the requirement of blocking water vapor from entering the inside of the execution is met, and the failure of the valve caused by the corrosion of the driving shaft sleeve is reduced.
