Abstract
The utility model provides a high pressure activity elbow, it includes that arc male joint, arc female joint, short connector and ladder lock nut constitute, and wherein, arc female joint one end combines with arc male joint, and the other end cartridge all adopts the steel ball location to be connected characterized by between public, female joint, between female joint and the short connector: the steel ball mounting hole is sealed by a rubber plug and a spring retainer ring, and oil injection and storage holes communicated with the end surface connected between every two joints are processed on the female joint and the short joint. The utility model has the advantages that: reasonable in design, safe and reliable, long service life, small, light in weight, the arc radius of public, female joint is only 54 mm.
Description
The utility model relates to a kind of oil, chemical industry of being applicable to and carries out the high pressure movable elbow that high-pressure liquid is carried.
At present, its structural type of high pressure movable elbow that is widely used in FLUID TRANSPORTATION is roughly: it comprises the arc tool joint pin, the arc female joint, short circuit head and ladder lock nut are formed, wherein, arc female joint one end combines with the arc tool joint pin, the other end is inserted in the short circuit head, public, between the female joint, all adopt steel ball to be located by connecting between female joint and the short circuit head, in the steel ball mounting hole, adopt jackscrew locking steel ball then, owing to belong to rigid sealing, in use because of pressure raises suddenly jackscrew is burst out sometimes, easily meet accident, moreover, because the seal face that joins between per two joints can't add Lubricants, cause between two joints rotational resistance big, serious wear reduces this class high pressure movable elbow working life, and maintain and replace is frequent, increased comprehensive cost of production, and it is public, the arc radius of female joint is bigger, is generally 64～94mm, causes whole movable joint volume, weight increases.
A kind of novel high-pressure movable elbow that the purpose of this utility model designs in order to overcome existing deficiency in the above-mentioned prior art just, this movable elbow is reasonable in design, and is safe and reliable, and volume is little, and is in light weight, long service life.
The purpose of this utility model realizes by following measure: this high pressure movable elbow comprises arc tool joint pin, arc female joint, short circuit head and ladder lock nut composition, wherein, arc female joint one end combines with the arc tool joint pin, the other end is inserted in the short circuit head, between the male and female joint, all adopt steel ball to be located by connecting between female joint and the short circuit head, the steel ball mounting hole is stifled and check ring sealing by glue, on female joint and short circuit head, all be processed with per two joints between the oiling oil storage hole that is communicated with of contact surface mutually.
In the utility model, the oiling oil storage hole all is provided with in pairs, is 45 ° of angles between two holes, and its bottom communicates; The arc radius of arc tool joint pin and arc female joint is preferably 54mm.
The advantage that the utility model is compared with prior art possessed is: reasonable in design, safe and reliable, long service life, volume is little, in light weight, the arc radius of male and female joint only is 54mm, since on female joint and short circuit head, all be processed with per two joints between the oiling oil storage hole that is communicated with of contact surface mutually, can add rare matter lubricant oil by it, rotational resistance between per two joint phase contact surfaces is greatly reduced, have special superiority, guaranteed continuously or when being interrupted high-voltage construction and using joint rotate reliability relatively flexibly.Moreover, because the steel ball mounting hole adopts the stifled and check ring sealing of elastic gum, increased buffer function, improved shock resistance greatly.
Accompanying drawing is that master of the present utility model cuts open figure.
The utility model is done with detailed description below in conjunction with accompanying drawing:
As shown in the figure: short circuit head (3) composition that this high pressure movable elbow comprises arc tool joint pin (1), arc female joint (2) and is linked with ladder lock nut (4), wherein, arc female joint (2) one ends combine with arc tool joint pin (1), the other end is inserted in the short circuit head (3), and the arc radius of arc tool joint pin (1) and arc female joint (2) is preferably 54mm.Between the male and female joint, all adopt three roads (or twice) steel balls (5) to be located by connecting between female joint and the short circuit head, (steel ball number in the circuit is then fixed according to actual conditions), steel ball mounting hole (9) is by glue stifled (6) and check ring (7) sealing, on female joint (2) and short circuit head (3), all be processed with per two joints between the oiling oil storage hole (8) that is communicated with of contact surface mutually, the oiling oil storage hole all is provided with in pairs, be 45 ° of angles between two holes, its bottom communicates.
Claims (3)
1, a kind of high pressure movable elbow, it comprises arc tool joint pin (1), arc female joint (2), short circuit head (3) and ladder lock nut (4) are formed, wherein, arc female joint (2) one ends combine with arc tool joint pin (1), the other end is inserted in the short circuit head (3), public, between the female joint, all adopt steel ball (5) to be located by connecting between female joint and the short circuit head, of the present utility model being characterised in that: steel ball mounting hole (9) is by glue stifled (6) and check ring (7) sealing, all be processed with on female joint (2) and the short circuit head (3) with per two joints between the oiling oil storage hole (8) of contact surface connection mutually.
2, high pressure movable elbow according to claim 1 is characterized in that: oiling oil storage hole (8) all is provided with in pairs, is 45 ° of angles between two holes, and its bottom communicates.
3, high pressure movable elbow according to claim 1 is characterized in that: the arc radius of arc tool joint pin (1) and arc female joint (2) is preferably 54mm.
