Description

Quick clamping fixture for valve leakage detection

Technical Field

The utility model relates to the technical field of valve detection tools, in particular to a rapid clamping fixture for valve leakage detection.

Background

At present, leakage of the valve before pressure test is observed, and the valve is fully judged whether to be assembled by the experience of pressure test personnel or not because a special clamp is not used, so that the condition of missing detection can occur; in addition, some fastening operations are required to be performed manually, so that the operation is very complicated and the working efficiency is reduced.

Therefore, a quick clamping fixture for detecting valve leakage is needed at present, and the problems that whether the existing valve is leaked or not is very complicated and inaccurate are solved.

Disclosure of Invention

The utility model provides a rapid clamping fixture for valve leakage detection, which solves the problems that the operation process is very complicated and inaccurate in the existing valve leakage detection mode.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

a valve leak detection quick clamp comprising:

the bottom plate is provided with a support column for placing the valve, and an L-shaped channel is arranged in the support column; one end of the L-shaped channel is positioned on the end surface of the support column far away from the bottom plate, and the other end of the L-shaped channel is positioned on the outer wall of the support column;

the limiting assembly comprises three corner cylinders and limiting rods, wherein the three corner cylinders are arranged on the bottom plate at intervals, one end of each limiting rod is connected with a main shaft of each corner cylinder, and each limiting rod is perpendicular to the main shaft of each corner cylinder.

Further, the support column is provided with the recess far away from the one end of bottom plate, be provided with the silica gel sealing pad in the recess, be provided with on the silica gel sealing pad with the communicating through-hole of L type passageway one end.

Further, the limiting rod is a component made of plastic.

Further, the bottom plate is connected with the support column, and the support column is connected with the corner cylinder through lock nuts.

Furthermore, the shape of the bottom plate is circular, and the three corner cylinders are circumferentially arranged on the bottom plate at equal intervals.

Further, the device also comprises a manual valve, and the manual valve is connected with the corner cylinder.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:

when the detected valve is put into the support column, and then when the 3 corner cylinders are ventilated, the limiting rod rotates to downwards compress the valve, water is injected into the valve at the upper end, the leakage quantity of the valve is checked at one end of the outer wall of the support column through the L-shaped channel on the support column, and when the detection is finished, the movement direction of the corner cylinders is changed by controlling the air inlet direction of the corner cylinders, and the limiting rod connected to the corner cylinders moves upwards to rotate by 90 degrees, so that the detected valve is quickly loosened. Compared with the method for judging whether the valve leaks or not manually by experience, the utility model can improve the working efficiency and the accuracy.

FIG. 1 is a schematic view of the internal structure of the present utility model;

fig. 2 is a schematic top view of the present utility model.

In the figure, marks and part names:

the device comprises a 1-bottom plate, a 2-supporting column, a 3-L-shaped channel, a 4-corner cylinder, a 5-limiting rod and a 6-valve.

Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings.

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In this embodiment, a valve leakage detection quick clamping fixture is provided, as shown in fig. 1-2, including:

the valve comprises a bottom plate 1, wherein a support column 2 for placing the valve is arranged on the bottom plate 1, and an L-shaped channel 3 is arranged in the support column 2; one end of the L-shaped channel 3 is positioned on the end surface of the support column 2 far away from the bottom plate 1, and the other end of the L-shaped channel is positioned on the outer wall of the support column 2;

the limiting assembly comprises three corner cylinders 4 and limiting rods 5, wherein the three corner cylinders 4 are arranged on the bottom plate 1 at intervals, one ends of the limiting rods 5 are connected with a main shaft of the corner cylinders 4, and the limiting rods 5 are perpendicular to the main shaft of the corner cylinders 4.

The detected valve is put into the support column 2, then when the 3 corner cylinders 4 are ventilated, the limiting rod 5 rotates to downwards compress the valve, water is injected into the valve at the upper end, the leakage of the valve is checked at one end of the outer wall of the support column 2 through the L-shaped channel 3 on the support column 2, when the detection is finished, the movement direction of the corner cylinders 4 is changed by controlling the air inlet direction of the corner cylinders 4, and the limiting rod 5 connected to the corner cylinders 4 moves upwards to rotate by 90 degrees, so that the detected valve is quickly loosened.
