Abstract
The utility model provides a straight-through viewing mirror for solving problems that when a traditional straight-through viewing mirror is utilized to watch whether fluid flows or not, fluid which flows or not is hard to be judged. The utility model comprises a valve body, and the valve body comprises a fluid channel and an observation channel, the liquid channel hole is provided with a pipeline adapting flange, and the observation channel hole is provided with a viewing mirror adapting flange, and the viewing mirror adapting flange is connected with a stressed top, and glass of the viewing mirror is fixed between the adapting flange and the stressed top, a blade wheel is arranged on the position which is close to the glass of the viewing mirror on the viewing channel. The blade wheel comprises a blade wheel bar and a blade wheel plate which is pivoted on the blade wheel bar, the blade wheel bar which is vertical to the liquid level direction of the liquid in the fluid channel is fixed on a casing body of the valve body. The utility model is suitable for liquid pipelines of petroleum, chemical industry and other industries.
Description
Technical field
The utility model relates to a kind of device of spying on, and particularly a kind ofly is applied to the straight-through visor on the fluid pipeline in oil, chemical industry and other industry.
Background technique
Carry in the operation at oil, chemical industry and other industrial liquid, need regularly to understand the mobility status of liquid in the pipeline, at present, often use straight-through visor to observe flow of fluid situation in the pipeline.The straight-through visor of tradition comprises gland, glass, adpting flange, and gland is fixed on glass on the adpting flange, and visor is connected in the pipeline by adpting flange, has flow of liquid out-of-date in pipeline, sees through visor and observes the inside flow of fluid situation.Yet because fluid properties complexity to be observed, as the homogeneous of quality, situations such as free from admixture are difficult to observe whether liquid is flowing in the visor, wait work to cause difficulty for observation, even can cause doing the judgement that makes mistake, and make visor can't bring into play the effect of application.
The model utility content
The utility model provides a kind of convenient straight-through visor of observing flow of fluid situation in the pipeline.
In order to achieve the above object, the utility model leads directly to visor, it comprises a valve body, described valve body comprises fluid passage and observes passage, described fluid passage mouth is provided with the pipeline adpting flange, described observation passway is provided with the visor adpting flange, the visor adpting flange is connected with gland, endoscopy glass is fixed between adpting flange and the gland, be provided with an impeller near the endoscopy glass place on the described observation passage, described impeller is made up of impeller stem and the impeller blade that is articulated on the impeller stem, and described impeller stem is fixed on the housing of valve body perpendicular to liquid levels direction in the fluid passage.
Preferably, described impeller stem is arranged on the nearest sideline of the elongation line middle distance endoscopy glass of fluid passage in observing passage.
Preferably, described gland is an annular or three-back-shaped.
Preferably, described impeller blade comprises 6 or 8 wheel sheets.
Preferably, the endoscopy glass place near both sides is provided with an impeller respectively on the described observation passage.
The straight-through visor of the utility model at the impeller of installing near the endoscopy glass place perpendicular to liquid level, makes flow of fluid to rotate by the impeller sheet by in the straight-through visor of tradition.When needs are observed the situation of flow of fluid in the pipeline,, whether just can accurately judge ducted liquid at the mobile speed that reaches flow velocity, thereby alleviate the burden of the work of observing by observing the rotation situation of pipeline middle period wheel.
Description of drawings
Fig. 1 is the half sectional view of the straight-through visor of the utility model;
Fig. 2 is that impeller is the front view of 6 wheel sheets in the utility model;
Fig. 3 is the side view of impeller shown in Figure 2.
Embodiment
The utility model provides a kind of straight-through visor, in order to solve the straight-through visor of tradition when observing liquid and whether flow, is difficult to the problem of judging whether liquid flows, below in conjunction with accompanying drawing the utility model is elaborated.
Referring to shown in Figure 1, the utility model leads directly to visor, comprises a valve body 1, and valve body 1 comprises fluid passage 2 and observe passage 3 that fluid passage is provided with pipeline adpting flange 4 for 2 mouthfuls, is connected with fluid pipeline to carry liquid; Observe passage and upward be respectively equipped with two visor adpting flanges 5 in the both sides of valve body 1 for 3 mouthfuls, visor adpting flange 5 is connected with gland 6, observes passage 3 and is used to install straight-through visor; Visor adpting flange 5 and gland 6 can be annular, can be annular in the present embodiment for three-back-shaped also; Endoscopy glass 7 is fixed between visor adpting flange 5 and the gland 6, endoscopy glass 7 places of observing close both sides on the passage 3 are provided with an impeller 8 respectively, as shown in Figure 2, impeller 8 comprises impeller stem 9 and is articulated in impeller blade 10 on the impeller stem 9, impeller blade 10 comprises 6 or 8 wheel sheets, impeller stem 9 is fixed on the inwall of valve body 1 perpendicular to liquid levels direction in the fluid passage 2, makes liquid can rotate by impeller bar 9 when mobile; The wheel sheet of described impeller blade 10 is vertical, spacer ring is established and is articulated on the impeller stem 9, makes when flow of fluid impeller sheet 10 rotates the rotation situation of easier observation impeller blade.
Wherein, in order to make liquid when mobile, the rotation of impeller 8 better, make the rotation of impeller 8 can reflect liquid ground mobility status better, described impeller stem 9 can be arranged on the nearest sideline of the elongation line middle distance endoscopy glass 7 of fluid passage 2 in observing passage 3, ducted liquid flows through from one side of impeller stem 9, makes impeller 8 obtain bigger power from current, and rotational velocity is faster.
The utility model is installed an impeller respectively near two endoscopy glass places in valve body, no matter seeing through the mobility status of liquid in that endoscopy glass observation pipeline so all is easy to, when in the pipeline flow of fluid being arranged, can impeller rotate, be more prone to observe flow of fluid situation in the pipeline by two impellers, alleviated the burden in the work, more whether the liquid in the display pipes is at the mobile speed that reaches flow velocity.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
