Description
Technical field
The utility model relates to a kind of duplex pass ball valve of good seal performance, belongs to technical field of mechanical equipment.
Background technique
Ball valve is a kind of open-shut device is that spheroid is driven by valve rod, and around the valve that ball valve axis rotates.Be mainly used in the regulation and control of fluid, producing and pipeline in life has a wide range of applications, but due to design and the restriction of conditions of manufacture, causing its sealability bad, easily leak.Often need two groups of pipeline interflow or triage operator simultaneously aborning, need to add valve respectively on two groups of pipelines, but often need two valve Simultaneous Switchings, be unfavorable for operation, and validity is low, be unfavorable for producing.
Model utility content
The technical problems to be solved in the utility model is for above deficiency, provides a kind of duplex pass ball valve of good seal performance, has and can control the first ball valve and the second ball valve simultaneously, good sealing effect, the advantage that structure is simple and easy to use.
For solving above technical problem, the utility model by the following technical solutions:
A duplex pass ball valve for good seal performance, comprises the first ball valve and the second ball valve, is provided with connection set between described first ball valve and the second ball valve;
The first valve ball is provided with in described first ball valve;
The second valve ball is provided with in described second ball valve;
The both sides up and down of described first valve ball and the upside of the second valve ball are equipped with connecting rod;
The both sides of described connecting rod are respectively provided with a retention device;
Described first valve ball and the second valve ball are connected on connection set by retention device.
Below the further optimization to such scheme:
The left and right sides of described first valve ball is provided with seal arrangement, elastic device and valve seat successively.
The left and right sides of described second valve ball is provided with seal arrangement, elastic device and valve seat successively.
Described seal arrangement is for sealing the first valve ball and the second valve ball.
After the utility model adopts above technological scheme, compared with prior art, have the following advantages: the utility model apparatus structure is simple, easy to use, can control the first ball valve and the second ball valve simultaneously; Between seal arrangement and valve seat, be provided with elastic device, make the sealability of the utility model device better.
