As a kind of preferred scheme, described emptying pressure relief device comprises an atmospheric valve, and described atmospheric valve is installed on the valve body and with medium channel and is communicated with.
After having adopted technique scheme, effect of the present utility model is: because pipeline ball-valve, comprise valve body, described valve body is provided with medium channel, be rotatablely equipped with on the described valve body and be used for the spheroid that switching station is given an account of the band cavity of matter passage, the spin axis place of described spheroid is equipped with valve rod, be sealed and installed with the adpting flange that is used to connect power plant on the described valve rod, be equipped with in the medium channel of described valve body along media flow direction and spheroid and contact the left valve component of sealing and contact the right valve component of sealing along the contrary direction of media flow and spheroid; Described left valve component comprises left valve seat bracing ring, on the described left valve seat bracing ring left valve seat is installed, described left valve seat bracing ring is provided with and makes the left load end face portion of left valve seat bracing ring along media flow direction forced-slip, is provided with between described left valve seat bracing ring and the valve body to make described left valve seat and spheroid contact the left elastic component of sealing; The emptying pressure relief device that is communicated with described medium channel is installed on the described valve body, therefore, in use, medium flows in the medium channel of valve body, the power plant actuate valve stem that is installed on the adpting flange is rotated, valve rod rotates and just drives the spheroid rotation, thereby switching station is given an account of the matter passage, and left valve seat bracing ring is provided with left load end face portion, therefore, medium produces pressure to left load end face portion, though left valve seat is opposite to the pressure direction that the medium channel inner peripheral surface also has suffered pressure medium of a bit of area and left load end face portion to be subjected to the point of contact of spheroid, but the lifting surface area of left load end face portion is can design area bigger, simultaneously, left elastic component produces elastic force to left valve seat bracing ring, and what left valve seat bracing ring was subjected to makes a concerted effort to remain along the media flow direction, lean to the spheroid outer circumferential face thereby promote left valve seat bracing ring, left valve seat and spheroid contact sealing; Right valve component then contacts sealing along contrary direction of media flow and spheroid outer circumferential face, and the valve body medium channel may be subjected to Temperature Influence and volumetric expansion by sealing back, left and right sides medium, it is big that pressure becomes, this moment can be by emptying pressure relief device safety relief, like this, the spheroid upstream side and the downstream side two way sealed of ball valve have just been realized, the two-way dual partition effect that stops is arranged, when a side sealing was lost efficacy, opposite side sealing also can guarantee the ball side sealing, guarantee that ball valve is long-term, safety, effectively, operation reliably.
Because described left valve seat bracing ring is provided with left mounting groove, described left valve seat is installed in the left mounting groove again; Described right valve seat bracing ring is provided with right mounting groove, and described right valve seat is installed in the right mounting groove, therefore, has just avoided when spheroid rotates left side valve seat and right valve seat to be squeezed out outside the groove, thereby has guaranteed that ball valve sealing is reliable.
Again because described left valve seat bracing ring and right valve seat bracing ring are equipped with the standby hard sealing surface with described spheroid fitted seal, therefore after when left valve seat and the use of right valve seat, wearing and tearing, can be by standby hard sealing surface and spheroid fitted seal, thereby further guarantee the sealing reliability of ball valve, prolong the working life of ball valve.
Again because described left valve seat bracing ring and right valve seat bracing ring are equipped with the standby hard sealing surface with described spheroid fitted seal, therefore, when left valve seat bearing ring and right valve seat bracing ring when spheroid moves, the standby hard sealing surface of bearing ring and spheroid keep metal hard-sealing, and the valve seat of elastic material is realized soft seal, metallic seal, effectively avoided valve seat to be damaged by the solid particle polluter in the medium, double seal, good sealing effect seals more reliable.
Again because described valve body comprises left valve barrel, right valve barrel and middle valve body, described left valve barrel and right valve barrel are welded on the left and right sides of valve body in described respectively, described spheroid is installed on the described middle valve body, welding connects in light weight than original bolt, the adhesive strength height, compact structure has avoided the interior medium of valve body to leak.
Again because described spheroid is provided with the last axle head and the lower shaft end of extending along spin axis, be installed with upper bracket and undersetting on the described valve body, the last axle head of described spheroid and lower shaft end are rotatably installed in respectively on upper bracket and the undersetting, described valve rod is connected with the described axle head of going up, general ball valve is to be rotatably installed on the valve body by upper valve rod and lower valve rod, this common ball valve in use, spheroid is except being subjected to the warping force that valve rod transmits, also be subjected to medium it is produced the impulse force that extends along medium channel, spheroid has been directly passed to upper valve rod and lower valve rod with the medium impulse force, therefore, occurring upper valve rod and lower valve rod bending deflection easily causes the ball valve unlatching dumb, sealing is also bad, the existence of last axle head and lower shaft end, make its medium produce impulse force and directly passed to valve body by spheroid, spheroid just can not pass to valve rod with impulse force, last axle head and lower shaft end length can design shortlyer, and the extension axis of close medium channel, its impulse force is reduced as far as possible, spheroid bears the flexural load of impulse force to its generation hardly, valve rod only is subjected to pure warping force, spheroid opens and closes more flexible, also avoid medium that the excessive sealability that causes of impulse force that spheroid produces is reduced, thereby improved the operational safety of ball valve.
Again because described valve rod is provided with the shaft shoulder, described valve rod one end runs through described valve body and is connected with spheroid, described adpting flange compresses the described shaft shoulder and fixedlys connected with described valve body, be provided with first seal ring between described adpting flange and the described valve rod, by fastening piece gland is installed detachably on the described adpting flange, be provided with second seal ring between described gland and the described valve rod, therefore, the good sealing effect at valve rod place is guaranteed in the double seal of first seal ring and second seal ring, prolong the working life of ball valve, when first seal ring and second seal ring lost efficacy simultaneously, can be with to press and detect, gland is disassembled, and valve rod can't be by the valve body internal pressure and bullet flies, after changing second seal ring, ball valve can effectively be worked equally, just ball valve is concentrated trimming during pipeline overhaul by the time, thereby guaranteed the normal use of pipeline, reduced maintenance cost simultaneously.
Again because between described valve rod and the spheroid, contacted conduction between valve rod and the valve body and contacted part, therefore, spheroid can produce static with left valve seat and right valve seat friction in rotation process, at this moment, contact the electric action of part, just static can be passed to valve rod by conduction, passing on the valve body and then importing the earth then, so just guarantee the static derivation, avoided static to cause spark and cause the burning of medium, guaranteed the safe transport of medium.
