Description
Technical field:
The present invention relates to pipeline fittings, pressurized container, pressure facility and valve, particularly the housing of pressure piping, pressurized container, pressure facility and valve and internals is connected sealing configuration.
Background technique:
The pressure piping interface of conveyance fluid medium, import and export and accent with the housing of all kinds of valves of the pressurized container of fluid storage medium, the pressure facility that improves flowing medium, control flows body medium, comprise core shell and core lobe and plunger and flap on valve seat and valve seat jack, the combination valve core in all kinds of valve valve pockets, all need connect seal or connection every slag.Existing internal thread, outside thread, flange, folder, butt welding, SOCKET WELDING, clamp, cutting ferrule, socket joint close-fitting and socket joint cunning such as are joined at the structure that is connected sealing or connects every slag respectively have excellent scarce.Wherein: though worm structure is simple compact, part is few, radial dimension is little, after the difficult processing of mouth of pipe screw thread, easy-to-rust, the corrosion dismounting difficult, when installing rotation is arranged and be not easy sealing, more inapplicable big latus rectum connects sealing.Though flange and reliable to clamping structure easy accessibility, sealing, be suitable for big or small latus rectum, part is many, radial dimension big, pipeline appearance protection inconvenience.Though butt welding and the SOCKET WELDING structure is the simplest, radial dimension is minimum, the most suitable big or small latus rectum, sealing are also the most reliable can not repeat dismounting and be heated place's yielding, usability attenuating.Though the dismounting of clamp structure is quick and convenient, non-circular clamp shell shaping is difficult, processing is also difficult.Though not rotation and sealing easily of obturator during the dismounting of cutting ferrule structure, simple compact, radial dimension is also little, rotates dismounting difficulty after the difficult processing of screw thread, easy-to-rust, corrosion of degree of tightness, also inapplicable big latus rectum.
Valve seat in the valve valve pocket generally all adopts the separated type valve seat construction except the monolithic construction of built-up welding on housing and directly processing, separated type valve seat and valve seat jack generally adopt the structure of fixed connection and sealing.Wherein: screw thread is fixed, screw (similar flange arrangement), SOCKET WELDING isostructural excellent lack existing aforementioned, and be pressed into the plastic deformation of angle single face and be pressed into socket joint close-fitting structures such as the two-sided plastic deformation of dovetail groove, though simple compact, close-fitting sealing surface difficult processing, connect unreliable, easy leakage, also inapplicable big latus rectum.For the hard sealing surface that makes ball valve, butterfly valve, stopcock and the optional sealed valve of plate valve class is not killed, few scratch, be suitable for flowing mediums such as slag slurry, high temperature, also adopt at the valve seat afterbody to add the floating valve seat structure that socket joint cunning that spring, cylindrical add seal ring is joined, promptly valve seat can axially reciprocal structure.Even in order to wear and tear evenly between the hard sealing surface, to wash away evenly, increase the service life, on ball seat end and ball core, be shaped on the gear of mating engagement in addition, make the every switch of ball core once promptly drive the structure that floating valve seat radially rotates to an angle.But the floating valve seat structure exists seal ring non-refractory, sealing difficulty, leak easily and the Gear Processing of mating engagement is debugged more defectives such as difficulty.If floating valve seat is become float flap or unsteady core lobe, not only there are not defectives such as seal ring non-refractory, sealing difficulty, easy leakage, because unsteady flap or unsteady core lobe just are seated in the middle of the valve pocket that is full of the pressure fluid medium, so do not need sealing.The hard sealing surface of floating valve seat is not killed, few scratch but also kept, and advantage, particularly ball valve, butterfly valve and the stopcock that is suitable for slag slurry, high temperature fluid medium can also keep to open or cut out only makes the rotating advantage of 90 degree.Can axially back and forth and radially rotate is the prerequisite that unsteady flap or unsteady core lobe keep the floating valve seat advantage, and valve rod or plunger and flap or flashboard or combination valve core in the existing valve valve pocket, being connected of core shell and core lobe on the combination valve core particularly, generally do not have axially back and forth and the advantage of rotation radially.Wherein: though flap lid or the structure that is threaded can be axially back and forth and radially rotation, but the screw thread easy-to-rust, Conncetion cimension is long, assembly space is big, except that the stop valve flap, core shell and core lobe is connected on the combination valve cores such as the butterfly valve that inapplicable axial Conncetion cimension is short, assembly space is little, ball valve, plate valve; Though the structure Conncetion cimension that T type groove, dovetail groove connect is short, join strength is relatively poor, damages easily, also is unfavorable for every slag; Particularly core shell and core lobe adopt linkage structures such as dovetail groove, spiral chute on the interior combination valve core of ball valve, butterfly valve and stopcock valve pocket, have also lost the advantage that 90 degree revolutions open and close.
In existing nonfluid machinery and architectural hardware, also have and adopt the structure that connects as elastic pawls such as EXPANSION ANCHOR BOLTS or expansion tubes.But can only be used in being connected and fixed between part, and can not be used in the connection sealing of flowing medium, more can not be used in the core shell of combination valve core and being connected on slag of core lobe.
Summary of the invention:
The purpose of this invention is to provide on two kinds of housings that are applicable to fluid line, container, equipment, valve, set port is connected sealing configuration with pipe fitting or accent with the elastic pawl of capping; Provide a kind of and be applicable to that the separated type valve seat is connected sealing configuration with the elastic pawl of valve seat jack in the valve valve pocket; A kind of core shell and core lobe on the interior combination valve core of ball valve, butterfly valve, stopcock, safety check and plate valve valve pocket that be applicable to is provided, or plug type stop valve, plug type screw down nonreturn valve valve pocket inner plunger be connected every the slag structure with the elastic pawl of flap, and the fluid impact that is stressed core lobe or the flap structure that just can radially rotate.
The present invention is directed in the above-mentioned background technology existing seal with screwed joint structure, flange with folder is connected sealing configuration, butt welding is connected sealing configuration with SOCKET WELDING, clamp connects sealing configuration, the defective of cutting ferrule connection sealing configuration existence; Adopt the fixed connection and sealing structure to be connected the defective that sealing configuration exists with floating valve seat at separated type valve seat in the existing valve valve pocket with the valve seat jack; The defective that exists every the slag structure that is connected that is connected core shell and core lobe on slag structure, particularly combination valve core at existing valve valve pocket inner valve stem or plunger and flap or flashboard or combination valve core; Defective at existing elastic pawl linkage structure existence; Propose to solve described defective, and obtain the technological scheme of beneficial effect, and realize purpose of the present invention.
