The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of oil and gas pipeline simulated leakage valve is provided.
The utility model is to be achieved through the following technical solutions:
The utility model provides a kind of oil and gas pipeline simulated leakage valve, this leakage valve comprises the valve body that is provided with leak holes, one end in described valve body is provided with connecting head, position in described valve body between described connecting head and described leak holes is provided with seat board, on described seat board, be provided with multiple valve openings, in described valve body, slidable fit has valve plug dish, on described valve plug dish, be provided with towards the one side of described seat board the valve plug that multiple length is not identical, and the not identical valve plug of multiple length is corresponding one by one with the setting position of described multiple valve openings.
Preferably, described valve plug is needle type valve plug.
Preferably, also comprise rotatable handle, described rotatable handle is connected with promotion rotating disk by the valve rod being connected with described valve body spiral, and described promotion rotating disk and described valve plug dish are rotationally connected.
Preferably, described promotion rotating disk is connected with described valve rod by valve rod connector.
Preferably, be provided with valve stem seal connecting body on described valve body, described valve rod is connected with described valve stem seal connecting body spiral.
The beneficial effects of the utility model are: can be continuously, multiregion, highi degree of accuracy regulate the fluid flow of the leakage valve of flowing through, and conveniently realizes the requirement of the higher experiment of precision, simple in structure, be convenient to manufacture.
Brief description of the drawings

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, the oil and gas pipeline simulated leakage valve mechanism schematic diagram that Fig. 1 provides for the utility model the utility model, the plan view of the oil and gas pipeline simulated leakage valve that Fig. 2 provides for the utility model, the side view of the oil and gas pipeline simulated leakage valve that Fig. 3 provides for the utility model.
The utility model embodiment provides a kind of oil and gas pipeline simulated leakage valve, this leakage valve comprises the valve body that is provided with leak holes 6, one end in valve body is provided with connecting head 1, position in valve body between connecting head 1 and leak holes 6 is provided with seat board 2, on seat board 2, be provided with multiple valve openings, in valve body, slidable fit has valve plug dish 5, on valve plug dish 5, be provided with towards the one side of seat board 2 valve plug 4 that multiple length is not identical, and the not identical valve plug 4 of multiple length is corresponding one by one with the setting position of multiple valve openings.
In use, the connecting head 1 of valve is connected with pipeline, and in the time of original state, the valve plug 4 on valve plug dish 5 is all positioned at seat board 2 valve openings, now without leakage rate.At the trial, make the valve plug 4 of different length will depart from step by step valve opening, fluid also will flow into valve body by valve opening, enter Leak hole and produce leakage rate.Preferably, valve plug 4 is needle type valve plug.The length of multiple needle type valve plugs is all not identical, when valve plug 4 separates and makes gradually with the valve opening on seat board 2, produce different leakage rates, the number separating with valve opening by adjusting valve plug 4, can be continuously, multiregion, highi degree of accuracy regulate the fluid flow of the leakage valve of flowing through, and adopts said structure, conveniently realizes the requirement of the higher experiment of precision, simple in structure, be convenient to manufacture.
In the time that valve plug 4 is separated with valve opening, can adopt different structures, preferably, this leakage valve also comprises rotatable handle 11, rotatable handle 11 is connected with promotion rotating disk 8 by the valve rod 9 being connected with valve body spiral, promotes rotating disk 8 and is rotationally connected with valve plug dish 5.Now, by rotatable handle 11 is rotated, the valve plug dish 5 gradually valve rod 9 being connected is pulled away from seat board 2, meanwhile, by adopting helix structure, can control very accurately the vent flow of fluid.In the time being rotatably connected, its concrete structure is: on valve body, be provided with valve stem seal connecting body 10, valve rod 9 is connected with valve stem seal connecting body 10 spirals.
