Description
Technical field
The utility model relates to valve field, particularly relates to a kind of forged steel integral type floating ball valve.
Background technique
Integral type floating ball valve is compared to conventional float ball valve, have that structure is simple, take up room little, the feature such as leakage point is few, but existing integral type floating ball valve, it is casting structure, manufacture cycle is long, casting quality is unstable, delivery date can not ensure, be difficult to the new demand meeting client, and traditional integral type floating ball valve, be seat ring is directly screwed in valve body to compress valve seat, the valve seat but such structure is is easily worn and torn while seat ring screws in valve body, cause the sealing of valve seat not firm, and the life-span is short.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of forged steel integral type floating ball valve, adopts one-piece integrated structure, without leaking leak source, avoiding under high pressure fastening piece to lose efficacy, causing seal leakage; Adopt forged steel valve body, structure is simple, cost is low, with short production cycle, quality of product is high.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of forged steel integral type floating ball valve, comprise: valve body, valve seat, spheroid, valve rod and handle, described valve seat and spheroid are arranged in valve body, one end of valve rod connects spheroid, the other end stretches out outside valve body and is connected with handle, gland is provided with between described handle and valve body, the arranged outside of described valve seat has seat ring, the arranged outside of described seat ring has an independently valve seat pressure ring, described valve seat pressure ring is threaded into valve body and pressed against valve seat and valve seat by connection mouth, O shape circle is provided with between described seat ring and valve seat pressure ring.
Preferably, described valve body adopts forged steel, and for integral type overall structure is without leaking leak source, avoids under high pressure fastening piece to lose efficacy, causing seal leakage.
Preferably, adopt locking nut to be connected with disc spring between described valve rod and handle, described disc spring is arranged between gland and handle, and locking nut is arranged at handle upper-end surface, makes the sealingly secure of valve rod reliable.
Preferably, between described handle and disc spring, be provided with locking plate, valve can only be opened to a direction.
Preferably, between described spheroid and valve rod, be provided with anti-static spring, prevent accumulation of static electricity and produce spark, improve the Security of floating ball valve.
Preferably, described spheroid also offers relief hole, prevent when the valve is closed, medium residual in valve sharply raises because of be rapidly heated gasification, pressure of the relatively-high temperature of surrounding environment, causes seal leakage, fastening piece inefficacy etc.
Preferably, described handle adopts two limit structure, handle is offered four restraining grooves, and arranges stop screw on the top of valve body, and when valve opening or when closing, the stop screw at two ends, left and right is collided with the restraining groove on handle simultaneously, ensures that switch puts in place.
The beneficial effects of the utility model are: the utility model (1), fluid resistance are little; (2), structure is simple, volume is little, lightweight; (3), sealing is reliable, reaches zero leakage; (4), with short production cycle, forged steel reliable in quality; (5), easy to maintenance, ball-valve structure is simple, and it is all more convenient to take replacement apart; (6), applied widely.
