The invention discloses an operating mechanism for simultaneously opening and closing two ball valves. The operating mechanism comprises a first quadrilateral hinge mechanism, a second quadrilateral hinge mechanism, a T-shaped connecting mechanism, an operating hand wheel, a clamping mechanism, a first ball valve rod, a second ball valve rod, a first key and a second key, wherein the first quadrilateral hinge mechanism is connected with the first ball valve rod, the second quadrilateral hinge mechanism is connected with the second ball valve rod, the T-shaped connecting mechanism is connected with the first quadrilateral hinge mechanism and the second quadrilateral hinge mechanism, the operating hand wheel drives the T-shaped connecting mechanism and is connected with the same, the first key is positioned on the first quadrilateral hinge mechanism, the second key is positioned on the second quadrilateral hinge mechanism, and the clamping mechanism is used for clamping the first key and the second key. The T-shaped connecting mechanism is connected with the two same quadrilateral hinge mechanisms, and the operating hand wheel drives the T-shaped connecting mechanism, so that the two ball valves can be simultaneously opened and closed.
Description
Technical field
The present invention relates to a kind of operating device, particularly relate to the operating device that a kind of two billiard ball valves open and close simultaneously.
Background technique
On the upper and long transfer line of commercial plant pipeline, pipeline is in parallel sometimes, and two billiard ball valves are installed simultaneously, also require in the working site to open simultaneously, close, or a deck valve door is opened, another deck valve door is closed.This requires two to be furnished with two operated valve switch gears, and does not reach the simultaneously purpose of valve switch.
Summary of the invention
Technical problem to be solved by this invention provides the operating device that a kind of two billiard ball valves open and close simultaneously, it utilizes two same quadrilateral linkages, T shape connects mechanism and connects respectively two same quadrilateral linkages, the operation handwheel drives T shape and connects mechanism, guarantees to open and close simultaneously the requirement of two billiard ball valves.
The present invention solves above-mentioned technical problem by following technical proposals: the operating device that a kind of two billiard ball valves open and close simultaneously, it is characterized in that, it comprises the first quadrilateral linkage, the second quadrilateral linkage, T shape connects mechanism, the operation handwheel, fastening device, the first ball-valve valve rod, the second ball-valve valve rod, first key, the second key, the first quadrilateral linkage is connected with the first ball-valve valve rod, the second quadrilateral linkage is connected with the second ball-valve valve rod, T shape connects mechanism and the first quadrilateral linkage, the second quadrilateral linkage connects, the operation handwheel drives and connects T shape and connects mechanism, first key is positioned on the first quadrilateral linkage, the second key mapping is on the second quadrilateral linkage, and fastening device is used for clamping first key, the second key.
Preferably, described the first quadrilateral linkage comprises the first upper hinge cover, the first hinge, the second hinge, the 3rd hinge, the second quadrilateral linkage comprises the second upper hinge cover, the 4th hinge, the 5th hinge, the 6th hinge, the first upper hinge cover is enclosed within on the first ball-valve valve rod, the second upper hinge cover is enclosed within on the second ball-valve valve rod, T shape connects an end of mechanism by the first hinge, the second hinge, the 3rd hinge is connected with the second upper hinge cover, T shape connects the other end of mechanism by the 4th hinge, the 5th hinge, the 6th hinge is connected with the second upper hinge cover, first key is positioned at the first upper hinge and puts, and the second key mapping puts in the second upper hinge.
Positive progressive effect of the present invention is: of the present invention simple in structure, simple to operation and convenient, operate simultaneously two deck valve gate switch.
Description of drawings
Fig. 1 is the structural representation of the operating device that opens and closes simultaneously of the present invention's two billiard ball valves.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technological scheme of the present invention in detail.
As shown in Figure 1, the operating device that the present invention's two billiard ball valves open and close simultaneously comprises the first quadrilateral linkage, the second quadrilateral linkage, T shape connects mechanism 3, operation handwheel 4, fastening device 5, the first ball-valve valve rod 11, the second ball-valve valve rod 21, first key 12, the second key 22, the first quadrilateral linkage is connected with the first ball-valve valve rod 11, the second quadrilateral linkage is connected with the second ball-valve valve rod 21, T shape connects mechanism 3 and the first quadrilateral linkage, the second quadrilateral linkage connects, operation handwheel 4 drives and connects T shape and connects mechanism 3, first key 12 is positioned on the first quadrilateral linkage, the second key 22 is positioned on the second quadrilateral linkage, and fastening device 5 is used for clamping first key 21, the second key 22.Fastening device clamps first key, the second key, and the operation handwheel drives two ball-valve valve rods by two quadrilateral linkages and promotes first key, the second key, can open simultaneously or close two billiard ball valves.The first quadrilateral linkage comprises the first upper hinge cover 1, the first hinge 13, the second hinge 14, the 3rd hinge 15, the second quadrilateral linkage comprises the second hinge sleeve 2, the 4th hinge 23, the 5th hinge 24, the 6th hinge 25, the first upper hinge cover 1 is enclosed within on the first ball-valve valve rod 11, the second upper hinge cover 2 is enclosed within on the second ball-valve valve rod 12, T shape connects an end of mechanism 3 by the first hinge 13, the second hinge 14, the 3rd hinge 15 is connected with the first upper hinge cover 1, T shape connects the other end of mechanism 3 by the 4th hinge 23, the 5th hinge 24, the 6th hinge 25 is connected with the second upper hinge cover 2, first key 12 is positioned on the first upper hinge cover 1, and the second key 22 is positioned on the second upper hinge cover 2.
As shown in Figure 1, the operation handwheel drives T shape and connects mechanism, makes two quadrilateral linkages mobile simultaneously, drives two ball-valve valve rod rotations, reaches the effect of opening simultaneously or closing two billiard ball valves, and is of the present invention simple in structure, convenience simple to operation, and using effect is good.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make various changes or modifications to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
