The utility model belongs to the technical improvement of the equipment of fluid switch valve. The utility model has the advantages of reliable and tight sealing, long service life, low resistance, flexible opening and closing, convenient repair, etc. The valve is used for the use of the fluid systems of water supply, steam supply, oil supply, etc.
Description
The utility model relates to a kind of butterfly valve that is used for fluid switch.
The butterfly valve kind that is used for fluid switch at present is more, commonly middle line style and two eccentric butterfly valve, the common deficiency that these two kinds of butterfly valves exist is that the sealing surface of valve plate when valve wide open is positioned at pipeline center, just in face of liquid stream Peak Flow Rate, sealing surface wear is very fast, life-span is short, and increases resistance.The maximum deficiency that middle line style butterfly valve exists is that sealability is not good, the switch effort.Mostly two eccentric butterfly valves are to utilize skeleton alive that seal ring is contained on the valve body, will unload whole valve down replacing from pipeline when the deficiency of Cun Zaiing is the major valve replacing seal ring that has been installed on the pipeline like this, this maintenance for large-scale valve is a trouble.
The purpose of this utility model provides a kind of eccentric HYDRAULIC SPHERICAL locking of tight list reliable, that the life-span is long, resistance is less, switch is flexible, easy to maintenance butterfly valve that seals.
The utility model realizes that the above-mentioned purpose technical solution is, greater than outlet end, import is a straight length an entrance point, exports the valve pocket that is constituted for the sphere pipe and is set in the valve body that is made of upper end band disk vertical pivot cover and horizontal pipe.Have the position of sphere that the sphere valve plate of band inlet opening is housed at valve pocket, inlet opening is at valve plate pressure ball face T RunddichtringO place, and the axis hole that valve plate matches with the upper valve rod bottom is a long hole shape; With sphere hold-down ring and screw sphere T RunddichtringO is fixed on the valve plate; Be equipped with on the valve plate and pass the manual electronic or pneumatic of valve pocket, valve body, O RunddichtringO, muff, stuffing box packing, sealing gland and outside or valve rod that pushswitch actuator is connected.Sealing gland is screwed on the disk of valve body vertical pivot set upper side.Sealing gland cylindrical 1/4th peripheries are provided with valve plate aperture positioning recess.Valve rod is made up of for two sections upper valve rod, lower valve rod, and the bottom of upper valve rod is oblate, is positioned at the straight length position of valve pocket import.The top of upper valve rod and manual electronic or pneumatic or pushswitch actuator binding, the bottom of upper valve rod links with screw rod and valve plate, screw rod bracelet one end is screwed on the valve plate, the polished rod of screw rod partly passes hole corresponding with it, upper valve rod bottom, its aperture is greater than the diameter of screw rod polished rod part, for orientation is slidingly matched.The top of lower valve rod is fixed on the valve plate with taper pin, and the following muff that endoporus is a long hole shape is passed in the bottom, and the bottom withstands on the pad; Lower valve rod passes the minimum diameter of the diameter of lower shaft hub sections less than the lower shaft bush hole, for directed (liquid flow path direction) is slidingly matched; Valve plate can directed (liquid flow path direction) be moved.Become 90 ° orientation on valve body and valve pocket, to open a hole with valve rod, load onto the valve plate seal-locking mechanism.The valve plate seal-locking mechanism is that locking cam is fixed on the lock shaft boom end, be positioned at tube hub, the locking axostylus axostyle passes locking moving rod (manual electronic or the pneumatic or surge) binding of lock sealing circle, lock shaft bushing, lock shaft rod seal filler, lock shaft rod seal gland and outside on the valve pocket.Lock shaft rod seal gland is screwed on valve body.
The utility model is owing to take abovementioned technology, and compared with prior art, difference is: (1) has improved the shape of valve pocket, makes valve pocket become entrance point greater than outlet end, and import is a straight length, and outlet is the pipe of sphere shape; (2) valve plate is the sphere valve plate that has inlet opening, and the axis hole that valve plate matches with the upper valve rod bottom is a long hole shape, and the ball face sealing circle is housed on the valve plate; (3) bottom of upper valve rod is oblate, upper valve rod and valve plate are to link with screw rod is movable, and lower valve rod and valve plate are to link with dowel fixes, and the muff of lower valve rod is the endoporus of long hole shape, the bottom of lower valve rod withstands on the pad, and valve plate can directed (liquid flow path direction) be moved; (4) set up the valve plate seal-locking mechanism; When (5) valve plate was closed, sealing surface promptly was subjected to the axial force of fluid to be subjected to radial force again, also is subjected to the compressing power of mechanical interlocking simultaneously, and the big more sealing of hydrodynamic pressure is tight more; (6) during the valve standard-sized sheet, valve plate departs from tube hub, and sealing surface is avoided the wearing and tearing of Peak Flow Rate.Advantages such as it is tight reliable to have sealing, and the life-span is long, resistance is little, switch is flexible, easy to maintenance.
