Abstract
The utility model relates to a self-balancing differential pressure ball valve. The self-balancing differential pressure ball valve comprises a valve body, two valve bases and two valve channels, a valve rod, fillers, a valve cover, a three-way type ball core and sealing rings respectively arranged between the three-way type ball core and the two valve bases, wherein one channel of the three-way type ball core and a rotary shaft of the three way type ball core are in a straight line; one channel of the valve body is communicated with the channel of the three way type ball core, one side of the valve body corresponding to the other channel of the valve body forms a cavity with a sealing ring; the other channel of the valve body and the cavity are communicated with two channels of the three-way type ball core; the three-way type ball core is also provided with a balancing hole which is communicated with the other channel of the valve body and the cavity. By adopting the technical proposal, the utility model realizes that when the valve is closed, the left and the right differential pressures are balanced and the operating distortion distance is very small, thereby greatly improving the service life of the ball valve and lowering the operating density.
Description
Technical field
The utility model relates to a kind of ball valve, relates in particular to a kind of self-regulation differential pressure ball valve.
Background technique
When traditional ball valve uses on pipeline at present, run under the bigger situation of pressure reduction, particularly the torque of heavy caliber ball valve generation is very big, it is slow and the model final controlling element selected for use is bigger like this to open the speed of ball valve, when running into the rising of urgency pressure anomaly, can occur that ball valve is opened difficulty and the generation that causes the accident, and the operation torque is excessive when opening ball valve valve rod or sealing surface is caused damage, so can reduce ball valve working life.
Summary of the invention
Open difficulty and reduce the shortcoming in working life in order to solve excessive the causing of operation torque that above-mentioned traditional ball valve runs into, the utility model provides a kind of self-regulation differential pressure ball valve.
Technical solution of the present utility model provides a kind of self-regulation differential pressure ball valve, comprise valve body, the two passes of two valve seats and valve body, valve rod, filler, valve gap, Three way type ball core, Three way type ball core and two valve base chambers respectively are provided with a seal ring, the passage of described Three way type ball core and the running shaft of Three way type ball core are a straight line, a passage and the described Three way type ball core passage of described valve body connect, one side valve body of another passage correspondence of valve body and seal ring form cavity, another passage of described valve body and cavity connect with the two passes of Three way type ball core respectively, also be provided with equalizing orifice on the Three way type ball core, described equalizing orifice is communicated with another passage of valve body and cavity.
Because design has equalizing orifice on the self-regulation differential pressure ball valve ball core that provides in the above-mentioned technical solution, realized when ball valve is closed automatic adjusting to pressure reduction, thereby reach the balance of pressure reduction, so no matter ball valve is opened or is closed, perhaps the variation of pressure can not influence the operation torque of ball valve, improve the advantage that manipulation strength reduces greatly working life greatly thereby obtain ball valve.
Description of drawings
Accompanying drawing 1 is an embodiment's of the present utility model structural representation.
Accompanying drawing 2 is that the A-A of the embodiment shown in the accompanying drawing 1 is to structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
It as shown in Fig. 1 and Fig. 2 the self-regulation differential pressure ball valve that is in opening state, comprise valve rod 3, filler 4, valve gap 5, passage 12 in left valve barrel 1 and the left valve barrel, passage 14 in right valve barrel 2 and the right valve barrel, left side valve seat 7 and right valve seat 8 and Three way type Metal Ball core 6, respectively be inlaid with seal ring 10 in left side valve seat 7 and the right valve seat 8, seal ring 10 can adopt material such as teflon, left side valve seat 7 and right valve seat 8 are provided with O type circle 9 with the valve body junction point, 6 times side canals of Three way type Metal Ball core 15 and ball core running shaft are linearly, the two passes in addition of Three way type Metal Ball core 6 linearly and with described is vertical with ball core running shaft following side canal 15 linearly, therefore Three way type Metal Ball core 6 inner passages can be considered the structure of approximate English " T " word, passage 12 in the left valve barrel and the passage 14 in the right valve barrel respectively with the left channel of Three way type Metal Ball core 6 and down side canal 15 connect.The seal ring of inlaying in the right side valve body of passage 12 correspondences in the left valve barrel and the right valve seat 8 10 has constituted cavity 13, and the passage 12 in cavity 13 and the left valve barrel is positioned on the straight line, and cavity 13 connects with the right channel of Three way type Metal Ball core 6.The position, middle, top of Three way type Metal Ball core 6 also is provided with equalizing orifice 11 linearly, and equalizing orifice 11 is vertical setting with ball core running shaft.
Because the setting of the seal ring 10 in aforesaid left valve seat 7 and the right valve seat 8 is arranged, make the inside of whole valve can be considered by Three way type Metal Ball core 6 and seal ring 10 and be divided into 3 chambers: the passage 12 in the left valve barrel can be considered a chamber with the seal ring 10 in the left valve seat 7; Passage 14 in the right valve barrel can be considered second chamber together with the inner passage of Three way type Metal Ball core 6; It is cavity 13 that seal ring 10 in right valve barrel and the right valve seat 8 forms the 3rd chamber.Therefore, when the opening state that is in shown in Fig. 1 and Fig. 2,3 passages of 3 chambers and Three way type Metal Ball core 6 all are in breakthrough status.And when thereby twisting valve rod 3 drove ball core throttle down, 3 chambers of whole valve internal were separated each other by Three way type Metal Ball core 6 and left and right sides seal ring 10, and this moment is by passage 12 and cavity 13 in the equalizing orifice 11 connection left valve barrels.Like this, ball core and two valve seats are realized left and right sides stress balance under pressure action of medium, so when valve closing, left and right sides pressure balance, the operation torque is very little, it is minimum to that is to say that pressure medium has been lowered to the influence of operation torque, the working life of also so simultaneously having improved valve rod, filler.
