Abstract
The utility model relates to the field of ball valves, in particular to a two-position three-way ball valve. The two-position three-way ball valve comprises a valve body. An axial channel which extends in the vertical direction is formed in the valve body. A valve rod is installed inside the axial channel in an inserted mode. The periphery of the valve rod is sleeved with a protective sleeve in an axially-limiting mode. The protective sleeve is provided with an inner circumference face and an outer circumference face, wherein the inner circumference face is matched with the valve rod in an attached mode, and the outer circumference face is matched with the inner wall of the axial channel of the valve body in an attached mode. The end portion of the protective sleeve axially extends out of the axial channel along the axial direction of the axial channel. According to the two-position three-way ball valve, impurities like aluminum scraps can be effectively prevented from entering the axial channel, and abrasion, caused by grinding of the impurities in a gap between the valve rod and the valve body, to the valve rod and the valve body is effectively avoided. Therefore, occurrences of the seizure phenomenon are reduced, and the service life of the two-position three-way ball valve is long.
Description
Technical field
The utility model relates to the ball valve field, particularly a kind of two-bit triplet ball valve.
Background technique
Existing two-bit triplet ball valve comprises valve body, valve rod, valve seat, be arranged at the valve ball in valve base cavity, be provided with the axial passage extended along the vertical direction in valve body, valve rod is plugged in axial passage, the top of valve rod is connected with the handle of aluminum, handle is connected by pin with the upper end portion of valve body, in use, pin is due to vibration, the reasons such as extruding occur loosening, handle is scratched, handle can produce the aluminium bits, the aluminium bits enter in the axial passage of valve body, during rotation valve rod, between valve rod and valve body, grind, can scratch valve rod and valve body, when the aluminium in axial passage is considered the quantity that reaches certain to be worth doing, to there will be and kill phenomenon, valve rod can not rotate.In addition, the bilateral symmetry up and down in valve ball in valve base cavity is provided with seal ring, employing face sealing between seal ring and valve ball, and sealing effect is poor, easily occurs leaking, and the working life of seal ring is short.
Summary of the invention
The purpose of this utility model is to provide a kind of two-bit triplet ball valve, with impurity such as aluminium bits in the solution prior art, enters the problem in the gap between valve rod and valve body.
To achieve these goals, the utility model adopts following technological scheme: the two-bit triplet ball valve, comprise valve body, be provided with the axial passage extended along the vertical direction in valve body, be fitted with valve rod in axial passage, the peripheral, axial of described valve rod is spacing is arranged with sheath, sheath have with the inner peripheral surface of valve rod close fit and with the outer circumferential face of the inwall close fit of valve body axial passage, the sheath end is axially stretching out outside axial passage of passage vertically.
On the periphery of described valve rod, offer for the groove to the sheath axial limiting, sheath has the protuberance be installed in groove.
Described sheath is made of plastics.
The spacing containment vessel that is provided with of the peripheral, axial of valve rod, containment vessel and sheath be the axially spaced-apart setting of passage vertically, containment vessel have with the inner peripheral surface of valve rod close fit and with the outer circumferential face of the inwall close fit of valve body axial passage, containment vessel adopts plastics to make.
Be provided with the radial passage of extending along left and right directions in valve body, axial passage and radial passage are intersection and distribute, be provided with valve seat in radial passage, be provided with valve ball in the inner chamber of valve seat, bilateral symmetry up and down in valve ball in valve base cavity is provided with seal ring, seal ring has the conical surface for being sealed and matched with valve ball, between seal ring and valve ball, is linear sealing.
The beneficial effects of the utility model: due to the peripheral, axial of valve rod spacing be arranged with sheath, sheath in use can not be moved along the vertical direction, and stretch out outside the axial passage of valve body the sheath end, sheath can effectively prevent that the impurity such as aluminium bits from entering in axial passage, effectively avoided grinding in the gap of impurity between valve rod and valve body and valve rod and valve body have been caused to wearing and tearing, and then reduced the generation of killing phenomenon, thereby, long service life of the present utility model.
Further, because adopting plastics, makes sheath, the hardness of being considered to be worth doing well below aluminium by the hardness of plastics, and when having a small amount of aluminium bits to enter axial passage, the aluminium bits can be inlaid in plastics, reduce the damage to valve body and valve rod.
Further, the containment vessel be made of plastics can be inlayed the aluminium bits that enter in axial passage, reduces the damage of aluminium bits to valve body and valve rod generation.
Further, between seal ring and valve ball, be linear sealing, good sealing effect, effectively avoided leakage.
