Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to a kind of floating ball valve.
Background technique
The spheroid of floating ball valve floats, and under the pressure of medium, spheroid can produce certain displacement and be pressed on the sealing surface of outlet end, guarantees the outlet end sealing; The main feature of floating ball valve is compact structure own, and sealing is reliable, and is simple in structure; Easy to maintenance, sealing surface and the sphere closed state of being everlasting is difficult for by the medium erosion; Easy operating and maintenance are applicable to general work media such as water, solvent, acid and rock gas, but also are applicable to the medium that operating conditions is abominable.
Traditional floating ball valve is constructed as follows: comprise valve body, valve gap, spheroid, valve rod and handle, valve body is connected setting with valve gap, and stem bottom is connected setting with spheroid, be provided with valve seat in the valve body, and spheroid places between the valve seat.When the floating ball valve of this structure was worked under low-temperature condition, the medium of internal flow was prone to freezed, and made that spheroid is difficult to rotate or even can't realize rotation, thereby made the work of whole floating ball valve be affected, and reduce working life.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of floating ball valve that can under the operating mode of low temperature, also can effectively work, increase the service life.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of floating ball valve, comprise valve body, valve gap, spheroid and valve rod, and valve body is connected setting with valve gap; Stem bottom is connected setting with spheroid; Be provided with valve seat in the valve body, the suitable setting of spheroid and valve seat is characterized in that: be provided with the spheroid through hole corresponding to the valve rod connection on the said spheroid.
Through adopting technique scheme, the gas-flow resistance in the time of can flowing through spheroid through hole buffer medium makes that when rotation valve rod opening force reduces, and makes whole floating ball valve under the operating mode of low temperature, also can effectively work, and increases the service life.
The utility model further is set to: be arranged with vacuum valve on the said valve rod, vacuum valve is provided with the vacuum valve through hole, and the other end of the corresponding spheroid through hole of valve rod is provided with passage, and passage and the conducting of vacuum valve through hole are provided with.
Through adopting technique scheme, can pour lubricant oil into through valve stem passage, lubricant oil can flow out from the vacuum valve through hole, and it is more flexible to make that valve rod rotates, and further prolong the working life of whole floating ball valve.
The utility model further is set to: the end face of the other end of the corresponding spheroid through hole of said valve rod is provided with lubricating cup, and lubricating cup and passage are conducted.
Through adopting technique scheme, can pour lubricant oil into through lubricating cup, prevent that water clock causes waste on the surface of valve rod in the lubricant oil falling.
The utility model further is set to: be provided with Sealing between said valve rod and valve body, valve body and the valve gap.
Through adopting technique scheme, further strengthen the sealing and the Security of the spheroid that floats.
Description of drawings
Fig. 1 is the utility model floating ball valve embodiment's a structural representation.
Embodiment
With reference to Fig. 1 the utility model floating ball valve embodiment is further specified.
A kind of floating ball valve comprises and draws together valve body 1, valve gap 2, spheroid 3, valve rod 4 and handle 5 that valve body 1 is connected setting with valve gap 2; Valve rod 4 bottoms are connected setting with spheroid 3, and valve rod 4 tops are connected setting with handle 5, are provided with two valve seats 6 in the valve body 1; Spheroid 3 places between two valve seats 6, is provided with spheroid through hole 31 with valve rod 4 connections on the spheroid 3, is arranged with vacuum valve 7 on the valve rod 4; Vacuum valve 7 is provided with vacuum valve through hole 71, and valve rod 4 is provided with passage 41 with respect to the other end of spheroid through hole 31, passage 41 and the 71 conducting settings of vacuum valve through hole; The other end of passage 41 relative vacuum valve through holes 71 is provided with lubricating cup 8, and (what need explain is here, and lubricating cup 8 can need not to be provided with, for preventing to fall in the lubricant oil water clock on the surface of valve rod; Cause waste, present embodiment is preferred, at valve rod 4 top is provided with a lubricating cup 8 with passage 41 conductings); Lubricating cup 8 is conducted with passage 41, is provided with Sealing 91 between said valve rod 4 and the valve body 1, is provided with Sealing 92 between said valve body 1 and the valve gap 2.
When floating ball valve is worked, the setting of spheroid through hole 31, the gas-flow resistance when can the hole buffer medium flowing makes that when rotation valve rod opening force reduces, and makes whole floating ball valve under the operating mode of low temperature, also can effectively work, and increases the service life; Being equipped with of passage 41 and vacuum valve through hole 71 makes when valve rod 4 rotations are dumb, splashes into lubricant oil, makes valve rod rotate flexibly; The setting of Sealing 91,92 makes the Security of floating ball valve and sealing all improve greatly.
