The utility model discloses can realize the three -dimensional transmission simultaneously.
Description
Technical field
This utility model relates to a kind of spool, particularly relates to a kind of threeway jacket structured valve spool.
Background technology
Valve is control parts in pipeline fluid induction system, and it is used to change path section and media flow direction, have water conservancy diversion, end, throttle, non-return, the function such as shunting or overflow release.The valve controlled for fluid, various valves used from simplest stop valve to extremely complex robot control system(RCS), its kind and specification are various, and the inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m from atomic little gauge valve to latus rectum.Can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid fluidly to flow, the operating pressure of valve can supertension from 0.0013MPa to 1000MPa, operating temperature is from the high temperature of the ultralow temperature of-270 DEG C to 1430 DEG C.
The control of valve can use the multiple kind of drive, as manually, electrically, surge, pneumatic, turbine, electromagnetic driven, electromagnetism surge, electro-hydraulic dynamic, air-or liquid-operated, spur gear, bevel gear driving etc.；Can be under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, or it is independent of transducing signal and is simply turned on and off, valve relies on driving or automechanism makes opening and closing element lift, sliding, swing or gyration, thus the size changing its flow area controls function to realize it.Conventional valves is generally one-way transmission or two to transmission, but this cannot meet the demand of some special operation conditions.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of threeway jacket structured valve spool, can realize three-dimensional transmission simultaneously.
This utility model solves its technical problem and be the technical scheme is that a kind of threeway jacket structured valve spool of offer, and described valve core is the hollow structure of bottom opening, and side is provided with perforate；The transverse width of described perforate is slightly less than valve core overall width；When described valve core is positioned at the center of valve pocket, two interfaces of valve pocket both sides are connected with described perforate by respective passage, and the interface bottom valve pocket is connected with bottom valve core by passage.
The latter half of described perforate is camber line structure, the top half of described perforate just position semicircular in shape structure to described arcuate structure centre position, the curvilinear structures that the two ends of described semicircular structure are tapered into by a curvature respectively is connected with the two ends of described arcuate structure.
The transverse width of described perforate is more than the 9/10 of valve core overall width.
Described valve core top is provided with the fixing post for being connected with operating mechanism.
Described fixing post is provided with through hole.
Beneficial effect
Owing to have employed above-mentioned technical scheme, this utility model is compared with prior art, have the following advantages that and good effect: spool of the present utility model has three-port structure, therefore can realize three-dimensional transmission simultaneously, and its valve core opening part is irregular curve structure, by the careful design of perforate can be realized flow-control in transmitting procedure, improve efficiency of transmission, meet special operation condition demand.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model.In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
Embodiment of the present utility model relates to a kind of threeway jacket structured valve spool, as it is shown in figure 1, described valve core 1 is the hollow structure of bottom opening, side is provided with perforate；The transverse width of described perforate is slightly less than valve core overall width；When described valve core 1 is positioned at the center of valve pocket, two interfaces of valve pocket both sides are connected with described perforate by respective passage, and the interface bottom valve pocket is connected with bottom valve core by passage.
When described valve core 1 is positioned at the center of valve pocket, the valve equipped with this valve core 1 can make two response circuit conductings simultaneously.When the reactor of the first response circuit needs repairing, three-way valve operating mechanism drives valve core 1 to rotate to suitable angle, now closes the first response circuit, the only second response circuit conducting；When the second road pipeline needs repairing, operating mechanism drives valve core 1 to rotate to suitable angle, then close the second response circuit, open the first response circuit.So can solve problem in the case of system is not stopped transport, substantially increase running efficiency of system.
As in figure 2 it is shown, the transverse width of described perforate is more than the 9/10 of valve core overall width.The latter half of described perforate is camber line structure 11, the top half of described perforate just position semicircular in shape structure 12 to described arcuate structure 11 centre position, the curvilinear structures 13 that the two ends of described semicircular structure 12 are tapered into by a curvature respectively is connected with the two ends of described arcuate structure 11.The perforate mode of valve core obtains through finite element analysis computation, by machining center, valve core is processed, from valve core structure figure, can be seen that valve core tapping is irregular curvilinear structures, linearly smooth, thus flow-control can be realized in transmitting procedure.
Described valve core 1 top is provided with the fixing post 2 for being connected with operating mechanism, and this fixing post 2 is provided with through hole 21, and this through hole 21, for fixing one end of connecting rod, the other end of connecting rod is provided with driving runner.When rotating driving runner, can directly drive valve core to rotate in valve pocket by connecting rod and fixing post, thus realize the switching of conductive channel.
It is seen that, spool of the present utility model has three-port structure, therefore can realize three-dimensional transmission simultaneously, and it is irregular curve structure at its valve core opening, by the careful design of perforate can be realized flow-control in transmitting procedure, improve efficiency of transmission, meet special operation condition demand.
