Abstract

The utility model discloses a cutoff alarm comprising a casing, an upper sealing cap and a base, wherein a fluid passage communicated with the casing inner cavity is arranged in the base, and a connecting tube is arranged at the outer end port of the fluid passage. The cutoff alarm is characterized in that the upper sealing cap is equipped with a longitudinal blind hole, a floating ball is arranged in the casing, a bearing rod is fixedly connected to the top portion of the floating ball, a probe is fixedly connected to the top portion of the bearing rod and is disposed in the blind hole, further, a contact switch is arranged in the lateral wall of the upper sealing cap, the longitudinal position of the contact switch is arranged correspondingly to the position of the probe when the floating ball is located at the bottom of the inner cavity of the casing, and an alarm device controlled by the contact switch is arranged outside the casing. The cutoff alarm can accurately detect flow rate and alarms without being influenced by the flow speed.

Description

The cutout alarm

Technical field

The utility model relates to a kind of cutout alarm that is used for fluid line.

Background technique

The extensive structure that the Pressure testing sheet is set in fluid line that adopts of existing flow alarm, when the flow alarm was installed on reflow pipe, when hanging down owing to the flow velocity in the pipeline, detection lug is detected pressures exactly, was difficult to reach the purpose that detects flow.

The model utility content

The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of cutout alarm is provided, and it is not subjected to the influence of flow velocity, can detect flow and warning exactly.

For achieving the above object, cutout alarm of the present utility model, comprise housing, upper cover, base, wherein be provided with the fluid passage that communicates with the housing inner chamber in the base, and be provided with connecting tube in the external port of fluid passage, it is characterized in that in upper cover, being provided with blind hole longitudinally, in housing, be provided with a ball float, a pole is connected at the top of ball float, the probe that is connected at the top of pole, probe is positioned at blind hole, is provided with a contact-making switch in the sidewall of upper cover, the position at probe place was provided with the warning device by contact-making switch control when the lengthwise position of contact-making switch was in the housing intracavity bottom corresponding to ball float outside housing;

During use, connecting tube is installed on the middle and lower part of fluid line, housing inner chamber and fluid line form a connecting vessels like this, lower or when cutout when liquid level in the fluid line, ball float drives probe and moves down, and close with contact-making switch, contact-making switch gets electric startup warning device; Because the position of probe is irrelevant with flow velocity by the decision of the liquid level in the pipeline, can detect flow exactly and also report to the police;

As further improvement of the utility model, also be provided with a guide rod in the lower end of described ball float, in the fluid passage of base, be provided with the guide hole plate that cooperates with guide rod; The may command ball float only moves up and down, and avoids contacting with the bigger remaining flow liquid of viscosity on the housing internal chamber wall, thereby avoids normally rising floating, improves sensitivity;

As further improvement of the utility model, described housing is a transparent material, also is provided with urceolus in hull outside, and the upper and lower end of urceolus is installed on respectively on upper cover, the base, and urceolus is provided with peephole, is provided with scale at the edge of peephole; Flow in the considerable fluid measured pipeline;

In sum, cutout alarm of the present utility model is not subjected to the influence of flow velocity, can detect flow and warning exactly.

Embodiment

By illustrated in figures 1 and 2, this embodiment's cutout alarm, the housing 1 that comprises glass material, be arranged at the urceolus 2 in housing 1 outside, upper cover 3, base 4, wherein urceolus 2 on, the lower end is installed on upper cover 3 respectively, on the base 4, urceolus 2 is provided with peephole 5, edge at peephole 5 is provided with scale, be provided with the fluid passage 7 that communicates with the housing inner chamber in the base 4, and in the fluid passage 7 external port is provided with connecting tube 8, be provided with blind hole 9 longitudinally in the upper cover 3, in housing 1, be provided with a ball float 10, a pole 11 is connected at the top of ball float 10, a probe 12 is connected at the top of pole 11, probe 12 is positioned at blind hole 9, in the sidewall of upper cover 3, be provided with a contact-making switch 13, pop one's head in when the lengthwise position of contact-making switch 13 is in the housing intracavity bottom corresponding to ball float 10 position at 12 places, outside housing 1, be provided with warning device 6 by contact-making switch 13 controls, as buzzer, warning light etc., also be provided with a guide rod 14 in the lower end of described ball float 10, in the fluid passage of base 4, be provided with the guide hole plate 15 that cooperates with guide rod 14;

During use, the bottom of connecting tube 8 with fluid line 16 is connected, housing inner chamber and fluid line 16 form a connecting vessels like this, lower or when cutout when liquid level in the fluid line 16, ball float 10 drives probe 12 and moves down, and is close with contact-making switch 13, and contact-making switch 13 gets electric startup warning device; Because the position of probe 12 is irrelevant with flow velocity by the decision of the liquid level in the pipeline, can detect flow exactly and also report to the police.
