Abstract

The utility model relates to a rotary support type jack, which is composed of a rotary nut, two ejector rods, two supporters and one rotary shaft, wherein both ends of the supporters are provided with sleeves while one end of the supporter is sheathed on the rotary shaft and the other end of the supporter is sheathed on the ejector rod; the ejector rods are oppositely screwed into the nut which is provided with forward buckles and backward buckles; the rotary nut enables the two ejector rods to move forwards and backwards. When a connecting flange of a valve is pushed away, the valve and a flange mat can be easily replaced.

Description

The rotary-supporting type jack
One, technical field
The utility model relates to a kind ofly to be changed valve or changes the rotary-supporting type jack that the flange mat is used.
Two, background technology
At present, it all is the butt flange that crowbar is pried open the valve both sides that the oil worker changes valve, takes down old valve and changes new valve, dismounting is all very hard, is difficult to levelling, and the several people is busy half a day and just valve is changed, can't guarantee once to change success, during because of the replacing valve, often the flange mat is made a mess of, caused leakage, sometimes be good and sound flange mat, the dismounting valve more than once could be good and sound, could guarantee not miss, and this work is to allow a job of the headache of oil worker.
Three, summary of the invention
The purpose of this utility model provides a kind of rotary-supporting type jack, solves the problem that the oil worker changes valve or changes flange mat difficulty.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of a swivel nut, two push rods, two supports, a rotating shaft, it is characterized in that supporting two ends and be provided with sleeve, one end is enclosed within the rotating shaft, one end is enclosed within on the push rod, push rod screws in the nut with positive left-hand thread relatively, swivel nut makes two forward and reverse motions of push rod, backs down the butt flange of valve, can easily change valve and flange mat.
One end of push rod is provided with male thread, and an end is provided with circle or criss-cross or M shape stay bearing plate.
Nut is many prismatics, is provided with the female thread of the positive left-hand thread of band that the male thread with push rod is complementary in it.
But angle is pacified a cover rotary-supporting type jack again in the rotating shaft, but angle revolves the butt flange of overhead-valve door, makes flange stressed more balanced.
That compared with the prior art the utility model has is simple in structure, change valve or the flange mat light, time saving and energy saving, guaranteed workmanship, be oil worker's good assistant.
Four, description of drawings

Five, embodiment
For further disclosing the technical solution of the utility model, be further described by embodiment below in conjunction with Figure of description:
The utility model is by a swivel nut 1, two are supported 2, two push rods 3, a rotating shaft 4 is formed, it is characterized in that supporting two ends and be provided with sleeve, one end is enclosed within the rotating shaft, one end is enclosed within on the push rod, push rod screws in the nut with positive left-hand thread relatively, swivel nut makes two push rod both forward and reverse directions motions, back down the butt flange of valve, can easily change valve and flange mat, in order to make the flange stress equalization, can in rotating shaft, pacify a cover rotary-supporting type jack again, but angle revolves the butt flange of overhead-valve door, make the distance equity of top flange, guarantee to change the quality of valve or flange.
