Embodiment Construction
[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0024] The specific embodiment of all special tool of the present invention, as figure 1 As shown, it includes an installation unit 1 and a disassembly unit 2. The disassembly unit 2 includes a frame body 21 on which a drive motor 25 is installed. Where support seat 24 middle part is provided with transmission shaft installation hole 241, as figure 2 As shown, the transmission shaft 28 extends into the transmission shaft mounting hole 241 and is relatively fixed with the Verser support seat 24 , and the driving motor 25 drives the Versus support seat 24 to rotate through the transmission shaft 28 . The frame body 21 is also provided with a transmission shaft fixing pressing piece 29 . The Vall support base 24 has a support and fixing structure for supporting and fixing the Vall 5. When the Vall 5 is fixed on the Vall support base 24, the Vall 5 axis e...

The invention relates to a Vall rubber dismantling device and a Vall special tool. The Veril special tool includes an installation unit and a dismantling unit. The dismantling unit includes a frame body, which is provided with a Veril support seat. The upper guiding movement is equipped with a pressure knife. When the valve is fixed on the valve support seat, the pressure knife corresponds to the gap between the rubber and the upper side groove wall of the valve body and its guiding movement direction is perpendicular to the axis of the valve. The valve support seat and / or the pressure knife mounting seat can rotate around the valve axis, and the knife head of the pressure knife has a wedge surface that pushes the rubber towards the lower groove wall of the valve body when it radially approaches the gap. The valve special tool of the invention is easy to operate, greatly improves disassembly efficiency and can avoid damage to the valve body.
Description
technical field [0001] The invention relates to a Vall rubber dismantling device and a Vall special tool. Background technique [0002] In the development of oil and gas fields, in order to increase the production of oil and gas wells, fracturing operations are often performed on downhole formations. The current fracturing pump trucks widely rely on high-pressure plunger pumps to pump liquid from low pressure to high pressure into oil and gas wells, press open formations, and generate oil and gas channels. The pump valve assembly in the high-pressure plunger pump is commonly known as valve body, which is mainly composed of valve body and rubber. The valve body has a rubber installation groove, and valve rubber is installed in it. Due to the high pressure, it often occurs that the Vall rubber is severely worn and the sealing performance is deteriorated. Therefore, the Vall rubber needs to be replaced frequently during the on-site operation. However, the Vall rubber and the ...
