Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of without friction two way seal plug valve, including valve body 1, after valve body 1 inner chamber machining (grinding), through Nickel Plating Treatment, make valve body 1 inner chamber have corrosion resistant, resistance to erosion, wear-resistant, corrosion resistance.Valve body 1 both sides are provided with pipeline communication mouth 101, and the inner side of connected entrance is respectively equipped with slide plate 2, and the side of slide plate 2 is sealing surface, and opposite side is inclined-plane, and the sealing surface of slide plate 2 is provided with groove 21.Being provided with resilient fluoro-elastomer sealing ring 15 in groove 21, viton seal ring 15 compression molding in groove 21, adds the adhesion of viton seal ring and valve body 1, substantially increases the sealing property of valve, service life.Cock 10 metal sealing seals the backing as elastic packing in the face of slide plate 2 metallic sealing section, makes valve when meeting with fire or other accidents, has dual-seal, improves the security reliability of valve.
Be installed with valve gap 3 and bottom 4 on valve body 1, valve can on-line maintenance, be not required to from pipeline, pull down valve, only valve bottom 4 need to be taken apart, exchange slide plate 2, easy to maintenance.Valve gap 3 is fixing with support 5 to be connected.
Valve rod 6 one end is drive end, in the other end of valve rod 6 stretches into support 5 and threadeds with swivel nut 7, and valve rod 6 uses multiple thread to greatly reduce the rotation number of turns of handwheel with the trapezoidal thread of swivel nut 7, and driving means can use Worm wheel transmission mechanism.
Jointly shown in conjunction with Fig. 1 and Fig. 2, it is rotationally connected between valve rod 6 and support 5.Swivel nut 7 is provided with gathering sill near the lateral wall of one end of valve body 1, and gathering sill includes vertical slot 71 and the translot 72 being mutually communicated, and support 5 is fixed with feather key 8, and feather key 8 is partially disposed in gathering sill；The other end of swivel nut 7 is provided with spiral end face 74 and is provided with pin-and-hole 73 on sidewall, finger 9 it is provided with in pin-and-hole 73, offering the vertical guide groove 52 coordinated with finger 9 on support 5, valve rod 6 is provided with part and accommodates the detent 61 of finger 9, and valve rod 6 is fixed with the block 62 limiting swivel nut 7；Swivel nut 7 is fixing with the upper shaft 11 of cock 10 to be connected, and is provided with stuffing seal 12 between valve gap 3 and upper shaft 11.Window 51 is offered in support 5 both sides, when filler position produces leakage, can increase online or change filler.The lower axle 13 of cock 10 inserts bottom 4, and the both sides of cock 10 are slidably connected with corresponding slide plate 2 respectively, and cock 10 is provided with flow-guiding mouth 14.
The upper shaft 11 of cock 10 and lower axle 13 one piece casting of cock 10 are structure as a whole, and during cock 10 unidirectional pressurized, upper shaft 11 and lower axle 13 have enough rigidity and intensity and bending resistance.The upper and lower axle of cock 10 have employed bearing with bottom 4, valve gap 3 place of cooperation, and the hardness of bearing ensure that upper shaft 11 and the accuracy of lower axle 13 location, prevents upper shaft 11 and lower axle 13 from being produced friction with bearing by the effect of pressure medium and wearing and tearing.
Being communicated with the pipeline 17 of pipeline communication mouth 101 and valve body 1 lumen outside valve body 1, pipeline 17 is provided with control valve 18, thus realizes the automatic leakage playing function of valve, prevents the abnormal boosting of valve pocket after valve completely closes.Foam cock 16 is installed on bottom 4, can blowdown cleaning online.
This valve also includes that indicating arm 20, one end of indicating arm 20 are provided with indicator 19, and the other end runs through valve rod 6 and fixing with swivel nut 7 is connected.Valve switch indicator 19 can accurately show the on off state of valve.I.e. when indicator 19 is parallel with pipeline, valve is opening；When indicator 19 is vertical with pipeline, valve is closed mode.
Operation principle of the present utility model is:
During valve opening, valve rod 6 rotates, feather key 8 slides in vertical slot 71, finger 9 slides in vertical guide groove 52, cock 10 first makes slide plate 2 depart from valve body 1 sealing surface with swivel nut 7 vertical movement, being limited by block 62 after swivel nut 7 motion certain distance and start to rotate, finger 9 is squeezed in detent 61, and feather key 8 slides in translot 72, cock 10 opens valve with swivel nut 7 90-degree rotation, and during this, the sealing surface of slide plate 2 valve body 1 is without Relative friction.
During valve closing, finger 9 makes to position between valve rod 6 and swivel nut 7, feather key 8 slides in translot 72, cock 10 reversely rotates 90 degree with swivel nut 7, after feather key 8 arrives well translot 72 termination, block 62 promotes swivel nut 7 to rotate, and feather key 8 slides along vertical slot 71, finger 9 is extruded detent 61 and falls into and slide along vertical guide groove 52 between support 5 and valve rod 6, and cock 10 struts slide plate 2 with swivel nut 7 slide downward and closes valve.
Valve is in switching process, and valve body sealing surface and slide plate sealing surface are without friction, abrasion, so that the service life of valve is long, switch moment is little, and runner is unobstructed, without turning phenomenon.
Additionally, the groove 21 of the sealing surface of slide plate 2 is through Nickel Plating Treatment, slide plate 2 metallic sealing section can be made to have corrosion resistant, resistance to erosion, performance wear-resistant, erosion-resisting.After cock 10 machining, through Nickel Plating Treatment, cock 10 corrosion resistant, corrosion-resistant can be made.After valve rod 6 roughing, carry out modifier treatment, after polish, carry out Nitrizing Treatment, its case hardness HV >=900 can be made, improve the wear resistance of valve rod 6 and swivel nut 7.Gathering sill and feather key 8 head on swivel nut 7 carry out Quenching Treatment, can make its case hardness HRC >=45, improve abrasion resistance properties, it is ensured that feather key 8 in gathering sill slidably can alleviate keying moment.
