Abstract
The utility model discloses an anti-striking protective device of a flowmeter. The anti-striking protective device comprises a tube body (1), a first rectifying flow stopping board (2) and a second rectifying flow stopping board (3), the first rectifying flow stopping board (2) and the second rectifying flow stopping board (3) are installed in the tube body in a spaced mode, a plurality of rectifying flow stopping holes are distributed in the first rectifying flow stopping board (2) and the second rectifying flow stopping board (3), and the rectifying flow stopping holes of the first rectifying flow stopping board (2) are different from the rectifying flow stopping holes of the second rectifying flow stopping board (3) in position, and all the parts form the anti-striking protective device. The anti-striking protective device is simple in structure, convenient to install, and firm in connection, fluid passes through a flow sensor in a regular state, measuring accuracy is improved, and the flowmeter is prevented from being damaged.
Description
Technical field
the utility model relates to flowmeter, is specifically related to a kind of anti-impact protective device of flowmeter.
Background technology
Industrial control automation requires more and more higher, various flow instruments use a lot, but industry spot installation and use complicated condition, can not well meet the measurement requirement of various flow instruments, due to misoperation, greatly affected the instrument measurement precision, even the major injury meter life, cause unnecessary loss.
Summary of the invention
the purpose of this utility model is: a kind of anti-impact protective device of flowmeter is provided, and the rectification fluid, allow fluid be rule state through flow sensor, improves measuring accuracy, avoids the damage of flowmeter.
Technical solution of the present utility model is: this anti-impact protective device comprises body, a rectification spoiler and No. two rectification spoilers; a rectification spoiler and No. two rectification spoiler intervals are arranged in body; some rectification restricted orifice distribute on rectification spoiler and No. two rectification spoilers; the rectification restricted orifice position of a rectification spoiler and No. two rectification spoilers is not identical, whole formation anti-impact protective device.
Wherein, at the two ends of body difference mounting flange.
During installation, this anti-impact protective device is arranged on fluid line, and is positioned at the front orientation of flowmeter; When fluid, through a rectification spoiler, fluid is forced to pass through along the rectification restricted orifice of plate face, a rectification of convection cell; When fluid arrives No. two rectification spoilers, because the position of the rectification restricted orifice of the rectification restricted orifice of No. two rectification spoilers and a rectification spoiler is different, fluid can not be fast through No. two rectification spoilers, must pass through along the rectification restricted orifice of No. two rectification spoilers, the rectification of convection cell secondary, fluid velocity is further cut down, and the formation rule fluid state is through flow sensor.
The utility model has the advantages that:
1, the fluid in body is through the rectification of a rectification spoiler and No. two rectification spoilers, reduced Flow Measuring System to the requirement of pipeline straight length, improve Flow Measuring System operability has been installed, saved industrial flow system installation cost, there is good economy.
2, after fluid is rectified, the fluid flow fields state is greatly improved, and reduces the impact of fluid fluctuation convection current system for measuring quantity, improves Flow Measuring System stability.
3, the rectification restricted orifice position of a rectification spoiler and No. two rectification spoilers, the impact of slowing down fluid to Flow Measuring System greatly, improve the Flow Measuring System life-span, improved the Flow Measuring System security.
4, simple in structure, install reliably, adopt the industrial standard flange connection before Flow Measuring System, be applicable to various flow control systems.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 body, No. 2 rectification spoilers, 3 No. two rectification spoilers, 4 flanges.
Embodiment
As shown in Figure 1; this anti-impact protective device comprises body 1, rectification spoiler 2 and No. two rectification spoilers 3; a rectification spoiler 2 and No. two rectification spoiler 3 intervals are arranged in body 1; some rectification restricted orifice distribute on rectification spoiler 2 and No. two rectification spoilers 3; the rectification restricted orifice position of a rectification spoiler 2 and No. two rectification spoilers 3 is not identical, whole formation anti-impact protective device.
Wherein, at the two ends of body 1 difference mounting flange 4.
During installation, this anti-impact protective device is arranged on fluid line, and is positioned at the front orientation of flowmeter; When fluid, through a rectification spoiler 2, fluid is forced to pass through along the rectification restricted orifice of plate face, a rectification of convection cell; When fluid arrives No. two rectification spoilers 3, because the position of the rectification restricted orifice of the rectification restricted orifice of No. two rectification spoilers and a rectification spoiler is different, fluid can not be fast through No. two rectification spoilers, must pass through along the rectification restricted orifice of No. two rectification spoilers, the rectification of convection cell secondary, fluid velocity is further cut down, and the formation rule fluid state is through flow sensor.
Claims (2)
1. the anti-impact protective device of flowmeter; it is characterized in that: this anti-impact protective device comprises body (1), a rectification spoiler (2) and No. two rectification spoilers (3); a rectification spoiler (2) and No. two rectification spoilers (3) interval are arranged in body (1); the upper some rectification restricted orifice that distribute of a rectification spoiler (2) and No. two rectification spoilers (3); the rectification restricted orifice position of a rectification spoiler (2) and No. two rectification spoilers (3) is not identical, whole formation anti-impact protective device.
2. the anti-impact protective device of flowmeter according to claim 1, is characterized in that: at the two ends of body (1) difference mounting flange (4).
