Further, the outer end of the valve rod in two main valve unit is set with connecting sleeve, and described handwheel is connected with the outer end of described valve rod by this connecting sleeve.
Further, the connecting sleeve of the valve rod outer end in two main valve unit is equipped with a sprocket wheel respectively, and is connected by chain between two sprocket wheels in two main valve unit.
Further, the pipeline between the first flow being connected to two main valve unit and the pipeline between the second runner being connected to two main valve unit are also connected to bypass valve.
Further, described pipeline comprises straight pipeline and curved pipe.
The beneficial effects of the utility model are: the flap in main valve unit of the present utility model coordinates with the sealing seat in two runners, form two direction of flow, thus synchronously drive the flap in two main valve unit to open or close two runners in two main valve unit by handwheel, and then a runner in two runners can be selected as direction of flow according to requirement of actual working condition, thus this device is provided with two washabilitys flowed to, meet the demand under different operating mode, achieve multiple choices, applicability is strong.Meanwhile, the pipeline of this device defines a cavity pressure control structure by connection safety valve, ensure that main valve unit internal pressure is no more than permitted value, carry in case press through in occurring, whole device safety and reliability can be made.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1, a kind of two combination chain moves fluid control device, comprise two main valve unit 1, be in transmission connection by sprocket chain strip transmission mechanism 3 between these two main valve unit 1, two main valve unit 1 include handwheel 11, valve rod 12, valve body 13, flap 14 and sealing seat 15, wherein, the outer end of described valve rod 12 is connected with handwheel 11, the inner of described valve rod 12 is connected with flap 14, lumen 131 is provided with in described valve body 13, laterally be provided with in valve body 13 and communicate with the lumen 131 of described valve body 13 and relative to the symmetrical first flow 132 of lumen and the second runner 133, a sealing seat 15 is respectively equipped with in first flow 132 and the second runner 133, the flap 14 be connected with valve rod 12 is movably arranged between the sealing seat 15 in first flow 132 and the sealing seat 15 in the second runner 133, the middle part of valve body 13 is provided with the fluid flow port 134 communicated with described lumen 131, connect respectively by pipeline between the first flow 132 of two main valve unit 1 and between the second runner 133, and described pipeline is connected with safety valve 2.
Furtherly, the outer end of the valve rod 12 in two main valve unit 1 is set with connecting sleeve 16, and described handwheel 11 is connected with the outer end of described valve rod 12 by this connecting sleeve 16.
Furtherly, the connecting sleeve 16 of valve rod 12 outer end in two main valve unit 1 is equipped with a sprocket wheel 31 respectively, and connected by chain 32 between two sprocket wheels 31 in two main valve unit 1, thus the chain 32 connected between two sprocket wheels 31 and these two sprocket wheels 31 define the sprocket chain strip transmission mechanism 3 of transmission two main valve unit 1.
Furtherly, the pipeline between the first flow 132 being connected to two main valve unit 1 and the pipeline between the second runner 133 being connected to two main valve unit 1 are also connected to bypass valve 4, the convenient trapped fluids medium removed in pipeline, to clear up pipeline.
