Abstract
The utility model discloses a uniflow flow meter which comprises a valve body and a valve cover arranged at the top of the valve body, wherein a fluid inlet and a fluid outlet are respectively arranged at the left side and the right side of the valve body. A vertically arranged L-shaped guide rod is arranged on the lateral wall at one side of the fluid outlet, the horizontal section of the L-shaped guide rod is positioned at the axis center of the fluid inlet and extends to the direction of the fluid inlet, and the tail end of the horizontal section of the L-shaped guide rod is provided with a spherical valve plate capable of moving in a left and right mode along the horizontal section of the L-shaped guide rod in a penetrating mode. A compression spring is arranged between the spherical valve plate and the vertical section of the guide rod, and the spherical valve plate abuts against the end portion of the fluid inlet under the action of the compression spring. The uniflow flow meter has the advantages that when fluid flows in from the fluid inlet, the valve plate can be pushed to move on the L-shaped guide rod, and the fluid enters the valve body. By means of the arrangement, the uniflow flow meter has unidirectional continuity and is good in adaptability during difficulty work conditions. By means of the simple arrangement, the valve plate of the flow meter is stressed in a balanced mode, and flow measurement factors are stable.
Description
Technical field
The utility model relates to a kind of industrial flow rate test instrument, especially a kind of single current flowmeter.
Background technology
The kind of the flowmeter of present industrial existence is a lot, but often volume is excessive for the flowmeter of petroleum industry, is not easy dismounting, and existing flowmeter mainly exists cost too high, be difficult for mediation during obstruction, can not realize the defectives such as real time measure to the oil well produced oil of single port.
Summary of the invention
The utility model is not intended to address the above problem, and a kind of single current flowmeter is provided, and it has overcome traditional petroleum industry flowmeter cost height, and is easy to assemble and can not be to the drawback of single port oil well real time measure, and its technical scheme that adopts is as follows:
A kind of single current flowmeter, comprise valve body and the valve gap that is installed in the valve body top, the left and right sides of valve body is respectively arranged with a fluid inlet and a fluid egress point, a L shaped guide rod of vertically installing is arranged on the sidewall of fluid egress point one side, the horizontal segment of L shaped guide rod is positioned on the fluid inlet axis centre co-current flow body importer to extension, the end of L shaped guide rod horizontal segment installs one can be along the spherical valve plate of L shaped guide rod horizontal segment move left and right, spherical valve plate and guide rod vertically are provided with a compression spring between the section, spherical valve plate is pressed over the end of fluid inlet under the effect of compression spring.
Described spherical valve plate is fixed together with the compression spring.
The sidewall of described fluid egress point one side is provided with a mounting blocks, and L shaped guide rod is installed on the mounting blocks by securing member.
The end of described fluid inlet is set to pre-small post-large taper surface, and spherical valve plate is provided with the O-ring seal that matches with taper surface.
The utlity model has following advantage:
Because the L shaped guide rod that arranges and be installed in compression spring and spherical valve plate on the L shaped guide rod, when being entered from fluid inlet by fluid, it is mobile at L shaped guide rod to promote valve plate, fluid is entered in the valve body, arrange thus, not only have unidirectional conduction but also in the operating mode of difficulty, have excellent adaptability, the simple setting, not only make the valve plate stress equalization of flowmeter, and the flow measurement coefficient is more stable.
Description of drawings
Fig. 1 is the structural representation of the utility model single current flowmeter.
Embodiment
Below in conjunction with the drawings and specific embodiments, single current flowmeter of the present utility model is described in further detail.
As shown in the figure, single current flowmeter of the present utility model, comprise valve body 1 and the valve gap 2 that is installed in the valve body top, valve gap 2 is connected and fixed with securing member after being placed in the top of valve body 1, the left and right sides of valve body 1 is respectively arranged with a fluid inlet 3 and a fluid egress point 4, the sidewall of fluid egress point 4 one sides is provided with a mounting blocks 8, L shaped guide rod 5 is installed on the mounting blocks 8 by securing member, the horizontal segment of L shaped guide rod 5 is positioned on fluid inlet 3 axis centre co-current flow body importer to extension, the horizontal section length of L shaped guide rod 5 extend into the fluid inlet end and is advisable, the terminal cross-under of L shaped guide rod 5 horizontal segments is installed one can be along the spherical valve plate 6 of L shaped guide rod horizontal segment move left and right, spherical valve plate 6 and guide rod vertically are provided with a compression spring 7 between the section, spherical valve plate 6 is fixed together with compression spring 7, and spherical valve plate 6 is pressed over the end of fluid inlet 3 under the effect of compression spring 7.
End that further can fluid inlet is set to pre-small post-large taper surface 9, spherical valve plate 6 is provided with the O-ring seal 10 that matches with taper surface, arrange thus when spherical valve plate 6 closures and can well stop passing through of fluid, guaranteed the acquisition precision of flowmeter.
In use, spherical valve plate 6 under the normal condition is because 7 effects of compression spring are in closure state, when having fluid to pass through, spherical valve plate 6 stressed is equivalent to stressed comprehensive of whole flow area, this resultant force makes spring shorten certain length, converts signal output to through the instrument displaying flow value by dynamic balance mechanism and multiplying arrangement then.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
