Abstract
The utility model relates to a pump tube coupling, comprising two flanges. Each flange is provided with a way tube and forms a body with the way tube. The characteristics are: The mouth of the way tube is provided with a spherical shell. The two spherical shells of the two way tubes match each other and sleeve together. A seal ring is arranged between the two spherical shells. A chain to prevent rotation is arranged between the two flanges. A rubber tube can be sleeved on the two way tubes. The pump tube to install the pump tube coupling can realize the bending between the two pump tubes and the convenience of installing deep-well pump. The working vibration of the deep-well pump has little impact force on the well pipe, thus the service life of the well pipe is prolonged.
Description
(1) technical field
The utility model belongs to the deep-well pump pipe connector.
(2) background technique
Existing deep-well pump pipe connector is actually two flange plate with bolton together, flange plate and water pump pipe are fixed as one, so just, a section pump line is connected into the water pump pipe that goes out that reaches hundreds of rice, fastening deep-well pump stretches in the deep-well under the pump line.Because the deep-well pipe range reaches hundreds of rice, well casing is crooked with complex geological conditions under the soil, camber ratio is bigger, the flange plate Pump pipe jointing device can not be crooked, and the pump line camber is little, when taking deep-well pump, deep-well pump is pressed on well casing and the well casing inboard rubs, and deep-well pump when work, motor vibration damages well casing easily, even causes deep-well to scrap.Deep-well pump works long hours under water, and rotor copper sheathing, steel bushing have loosening slightly, and deep-well pump produces strong vibration, and the sandstone material that filter pipe is outer shakes and falls in the well casing, causes the deep-well pump damage in impeller, also can cause the well casing breakage, causes disused well.
(3) summary of the invention
The utility model is for overcoming the above-mentioned deficiency of existing pump pipe connector, provide a kind of energy crooked Pump pipe jointing device, it and pump line tighten together, and the pump line that reaches hundreds of meters can be crooked with the bending of well casing, obviously reduces the friction between pump line and the well casing.
The technical solution of the utility model is to add at a certain distance to have spherical shell shape coupling arrangement between two pump lines that link, to realize connecting the crooked and sealing of pump line.This Pump pipe jointing device comprises two flange plate, each flange plate have a siphunculus and with siphunculus be one, it is characterized in that: at the siphunculus mouth one spherical shell is arranged, the spherical shell of two siphunculus matches and is nested together mutually, between two spherical shells seal ring is arranged; Between two flange plate, be provided with the chain of rotation inhibiting.
Above-mentioned Pump pipe jointing device is characterized in that: rubber pipe at the two siphunculus overcoat, rubber pipe has one section to be bellows.
This Pump pipe jointing device is taked said structure, connect with spherical shell, realize the bending between two pump lines, and bend angle is bigger, the pump line that reaches hundreds of meters is according to circumstances every between two two pump lines that connect a Pump pipe jointing device being installed about 30 meters or 10 meters, hundreds of meters pump line just can be crooked with the bending of well casing, well casing only play the guiding role, and obviously reduces the friction between pump line and the well casing, and it is very convenient that deep-well pump is installed, during the deep-well pump operational vibration, little to the percussion power of well casing; Deep-well pump works long hours under water, even that rotor copper sheathing, steel bushing have slightly is loosening, deep-well pump produces strong vibration, very little to the collision of filter pipe, the outer sandstone material of filter pipe is difficult for shaking and falls in the well casing, has prolonged the working life of deep-well; The sealing of overcoat rubber pipe is more reliable, the rotation angle of two flange plate about deep-well pump work timing system of the chain between two flanges.Can be at deep-well pump overcoat rubber ring, vibration-isolating effect is better.

(5) embodiment
The specific embodiment of this Pump pipe jointing device is seen Fig. 1, it comprises flange plate 1 and flange plate 15, flange plate 1 is an one with siphunculus 4, flange plate 15 is an one with siphunculus 12, it is characterized in that: spherical shell 7 outside the reducing section 6 of siphunculus 4 has, spherical shell 10 in the reducing section 11 of siphunculus 12 has, outer spherical shell 7 match with interior spherical shell 10 and are enclosed within outside the interior spherical shell 10, interior spherical shell 10 has circular groove, and seal ring 8 is installed in circular groove and is built between two spherical shells; Be provided with the chain 16 of two rotation inhibiting between two flange plate 1 and flange plate 15, the two ends of chain 16 are connected in flange plate 1 and flange plate 15 respectively.Present embodiment rubber pipe 5 at siphunculus 4 and siphunculus 12 overcoats, and rubber pipe 5 has one section to be bellows 9.
Installing and using of present embodiment sees that Fig. 2, this Pump pipe jointing device are connected between two pump lines, tightens together with bolt 20 and last pump line 17, between flange plate 1 and flange plate 18 sealing gasket 19 is installed.
Claims (2)
1, this Pump pipe jointing device, it comprises two flange plate, each flange plate have a siphunculus and with siphunculus be one, it is characterized in that: at the siphunculus mouth one spherical shell is arranged, the spherical shell of two siphunculus matches and is nested together mutually, between two spherical shells seal ring is arranged; Between two flange plate, be provided with the chain of rotation inhibiting.
