Abstract
Provided is a valve flange expansion opener. The problem that an existing valve replacing and maintaining tool is complicated in operation, large in labor intensity and unsafe is mainly solved. The valve flange expansion opener is characterized in that a flange clamping gap (4) is respectively under a flange left top block (1) and a flange right top block (2), the flange right top block (2) is fixedly connected at the right end of a hydraulic cylinder (3), the flange left top block (1) is fixedly connected at the left end of the hydraulic cylinder (3), and the hydraulic cylinder (3) is communicated with a manual hydraulic pump through a pipe. The valve flange expansion opener has the advantages of being simple in operation, low in labor intensity, safe and reliable.
Description
Technical field:
The utility model relates to a kind of replacing valve instrument used, especially valve flanges expander.
Background technology:
In oil extraction in oil field field, valve is used widely.In the time of replacing valve and maintenance, need to take off valve with instrument.And existing replacing valve and maintenance tool be because reasons in structure exists complicated operation, the large and unsafe problem of labour intensity, affects replacing valve and maintenance efficiency.
Utility model content:
In order to overcome existing replacing valve and maintenance tool complicated operation, the large and unsafe problem of labour intensity.The utility model provides a kind of valve flanges expander.This valve flanges expander has simple to operate, the feature that labour intensity is low and safe and reliable.
The technical solution of the utility model is: this valve flanges expander comprises the left jacking block of flange, the right jacking block of flange and hydraulic cylinder.Under the left jacking block of flange and the right jacking block of flange, have respectively the blue gap of block-regulations, the right jacking block of flange is fixedly connected on hydraulic cylinder right-hand member, and the left jacking block of flange is fixedly connected on hydraulic cylinder left end, and hydraulic cylinder is connected with hydraulic hand-pump by pipeline.
The utlity model has following beneficial effect: this valve flanges expander is owing to there being respectively the blue gap of block-regulations under the employing left jacking block of flange and the right jacking block of flange, the right jacking block of flange is fixedly connected on hydraulic cylinder right-hand member, the left jacking block of flange is fixedly connected on hydraulic cylinder left end, the structure that hydraulic cylinder is connected with hydraulic hand-pump by pipeline, utilize hydraulic cylinder distending valve two ends pipe flange, so simple to operate, and labour intensity is low, safe and reliable replacing and maintenance valve, and simple in structure.Thus this valve flanges expander have simple to operate, the feature that labour intensity is low and safe and reliable.
Brief description of the drawings:
Accompanying drawing 1 is the utility model structural representation.
The left jacking block of 1-flange in figure, the right jacking block of 2-flange, 3-hydraulic cylinder, the blue gap of 4-block-regulations.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, this valve flanges expander comprises the left jacking block 1 of flange, the right jacking block 2 of flange and hydraulic cylinder 3.The right jacking block 2 of the left jacking block 1 of flange and flange is semicircle, the left jacking block of flange radially has the blue gap 4 of block-regulations for 1 time, the right jacking block of flange radially has the blue gap 4 of block-regulations for 2 times, the right jacking block 2 of flange is fixedly connected on hydraulic cylinder 3 right-hand members, the left jacking block 1 of flange is fixedly connected on the piston of hydraulic cylinder 3 left ends, and hydraulic cylinder 3 is connected with hydraulic hand-pump by pipeline.
When actual use:
Left the flange of this valve flanges expander jacking block 1 and the right jacking block 2 of flange are fastened in respectively on the flange of valve two ends pipeline, then press hydraulic hand-pump, the piston of hydraulic cylinder 3 left ends is outside stretching out, outwards promote the flange of valve two ends pipeline by the left jacking block 1 of flange and the right jacking block 2 of flange, valve is easily taken out between the flange of valve two ends pipeline, complete replacing valve and maintenance operation.
This valve flanges expander, through field experiment, compared with general tool, is raised the efficiency more than 3 times, and a people just can operate.
Claims (1)
