Abstract

A clamping device capable of replacing flange piece bolts under pressure comprises an upper clamping bolt and a lower clamping bolt which penetrate through centers on two sides of a groove-shaped support and are symmetrically distributed. The clamping bolts are adopted to fix flange pieces through the groove-shaped support, temporarily serve as fastening bolts for fixing the two flange pieces and simultaneously replace rusted fastening bolts so as to achieve the purpose of replacing the fastening bolts in the condition of not stopping production. Therefore, cost is saved, economic benefit is improved, and simultaneously staff safety is ensured.

Description

A kind of clamping device of replace with pressure flange plate bolt
Technical field
The utility model belongs to field of machining, relates to a kind of device of changing the flange plate bolt, especially a kind of clamping device of replace with pressure flange plate bolt.
Background technology
Existing various process pipe is realized connecting with flange connection, uses bolted.Because production technology needs, fluid has very much certain pressure in the pipeline; Because working environment is moist, fastening bolt is under the larger environment of humidity for a long time, and corrosion can occur, and affects bolt strength, causes security of system hidden danger simultaneously.And change the bolt that corrosion has occured, and need generally speaking to release ducted pressure, again it is changed.But because arts demand can not stop production to overhaul, replacing can cause flange connections to reveal to make system pressure unstable by force, and can't guarantee staff's safety.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of clamping device of replace with pressure flange plate bolt is provided, this device can be changed the fastening bolt of flange generation corrosion in situation about not stopping production, and has not only reduced cost, has also guaranteed staff's safety.
The purpose of this utility model solves by the following technical programs:
A kind of clamping device of replace with pressure flange plate bolt comprises through the Troffer both sides, and the upper fishbolt and the lower fishbolt that arrange in opposite directions; Described upper fishbolt and lower fishbolt are arranged on the same axis.
Center, the above-mentioned Troffer both sides Ф 14.5 that holes respectively, tapping M16 * 1.5.
Above-mentioned upper and lower fishbolt adopts the fishbolt of M16 * 1.5.
The utility model adopts fishbolt, by Troffer flange plate is fixed, make it temporarily serve as the fastening bolt bolt of fixing two flange plates, change simultaneously the fastening bolt of corrosion, having reached in situation about not stopping production the fastening bolt to corrosion changes, save cost, when having improved economic benefit, guaranteed staff's safety.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1 and Fig. 5, a kind of clamping device of replace with pressure flange plate bolt comprises through Troffer 2 both sides, and the upper fishbolt 1 and the lower fishbolt 9 that arrange in opposite directions; Described upper fishbolt 1 is arranged on the same axis with lower fishbolt 9.Center, the Troffer 2 both sides Ф 14.5 that holes respectively, tapping M16 * 1.5.Upper and lower fishbolt adopts the fishbolt of M16 * 1.5.
Referring to Fig. 2-4, utilize the utility model that the corrosion bolt 8 on the flange plate 3 is changed.Pipeline 5 links together by the mode that flange connects, and two flange plates 3 are fastening by four groups of nuts 6 and bolt 7, also is provided with gasket seal 4 to guarantee the sealing of pipeline between two flange plates 3, prevents that pressure from leaking; During replacing, the up and down fishbolt 1,9 of this device is positioned over the outer end of two adpting flange sheets 3, near the corrosion bolt 8 that corrosion occurs, use monkey wrench to regulate simultaneously up and down fishbolt 1,9, locked Troffer 2 and flange plate 3 are realized the clamping of flange plate 3 by Troffer 2, this moment just can be in situation about not stopping production, the replacing corrosion bolt 8 of safety has reached the cost that economizes on resources, and guarantees the purpose of staff's safety.
