Description
Technical field
The utility model relates to the technology of flowmeter, particularly relates to a kind of technology of adjustable plug-in type vortex shedding flow meter.
Background technology
The plug-in type vortex shedding flow meter is a kind of flow instrument, during use its vortex street measuring head is inserted the pipeline ad-hoc location, can measure the local flow of this position.
In the structure of existing plug-in type vortex shedding flow meter, tubular stinger all is inserted in one and is provided with in the pedestal of tubular intracavity, the inner peripheral surface hermetic seal of the outer peripheral face of tubular stinger and pedestal tubular intracavity merges fixing, and converter and vortex street measuring head are installed on the two ends up and down of tubular stinger respectively; Existing plug-in type vortex shedding flow meter is because the length of tubular stinger insertion pedestal is changeless, the length that the vortex street measuring head stretches out the pedestal lower end also is changeless, therefore the vortex street measuring head insertion depth of every kind of plug-in type vortex shedding flow meter all is changeless, when using, the user must select the plug-in type vortex shedding flow meter of different model according to the demand of the different measuring degree of depth, therefore the user need purchase the plug-in type vortex shedding flow meter of multiple model to satisfy kind of a demand that fathoms, thereby increased the cost expenditure, and must cut off pipeline need clean pipeline or take out the maintenance of vortex street measuring head when measuring the time, therefore use and safeguard also very inconvenient.
The utility model content
At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides a kind of user cost of saving and pays, and use and easy to maintenance, can regulate the adjustable plug-in type vortex shedding flow meter of vortex street measuring head insertion depth.
In order to solve the problems of the technologies described above, a kind of adjustable plug-in type vortex shedding flow meter provided by the utility model comprises pedestal, vortex street measuring head, tubular stinger and converter; Described pedestal is provided with the tubular intracavity of both ends open, and described tubular stinger is movably set in the tubular intracavity of pedestal, and its outer peripheral face engages with the inner peripheral surface hermetic seal of the upper end open of pedestal tubular intracavity; Described vortex street measuring head is installed in the lower end of tubular stinger, and described converter is installed in the upper end of tubular stinger; It is characterized in that: described pedestal is provided with the ball valve that is used to control its tubular intracavity break-make, and described pedestal is provided with a regulating device;
Described regulating device comprises handwheel, screw mandrel and at least one connecting link, described screw mandrel rotates and is installed on the pedestal, and its parallel axes is in the axis of tubular stinger, and described handwheel is fixed in the screw mandrel upper end, one end and the tubular stinger of every connecting link are affixed, and the other end is connected with wire rod thread.
Further, described pedestal is provided with rule, and the scale increase and decrease direction of described rule is parallel to the axis of tubular stinger.
The adjustable plug-in type vortex shedding flow meter that the utility model provides, can move up and down by rotating handwheel drive tubular stinger, thereby can regulate the insertion depth of vortex street measuring head according to the demand of the different measuring degree of depth, can save the cost that the user purchases instrument, and drive and after the vortex street measuring head rises to ball valve top ball valve is closed by rotating handwheel, can under situation, clean pipeline or take out the vortex street measuring head and carry out on-line maintenance need not to cut off pipeline, use and safeguard very convenient.
Description of drawings
Fig. 1 is the structural representation of the adjustable plug-in type vortex shedding flow meter of the utility model embodiment.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.
As shown in Figure 1, a kind of adjustable plug-in type vortex shedding flow meter that the utility model embodiment is provided comprises pedestal 1, vortex street measuring head 2, tubular stinger 3 and converter 4; Described pedestal 1 is provided with the tubular intracavity of both ends open, and described tubular stinger 3 is movably set in the tubular intracavity of pedestal 1, and its outer peripheral face engages with the inner peripheral surface hermetic seal of the upper end open of pedestal tubular intracavity; Described vortex street measuring head 2 is installed in the lower end of tubular stinger 3, and described converter 4 is installed in the upper end of tubular stinger 3; It is characterized in that: described pedestal 1 is provided with the ball valve 5 that is used to control its tubular intracavity break-make, and described pedestal 1 is provided with a regulating device;
Described regulating device comprises handwheel 6, screw mandrel 7 and two connecting links 8, described screw mandrel 7 rotates and is installed on the pedestal 1, and its parallel axes is in the axis of tubular stinger 3, and described handwheel 6 is fixed in screw mandrel 7 upper ends, one end and the tubular stinger 3 of every connecting link 8 are affixed, and the other end is threaded with screw mandrel 7.
Among the utility model embodiment, described pedestal 1 is provided with rule 9, and the scale increase and decrease direction of described rule 9 is parallel to the axis of tubular stinger 3, and described connecting link 8 is provided with pointer 10.
The utility model embodiment is under normal condition, and ball valve is in opening state, and the two ends up and down of the tubular intracavity of pedestal are communicated with at this moment;
