Abstract
The utility model discloses a joint connecting and sealing device, comprising a double-head straight joint and a high-pressure metal hose, wherein one end of the double-head straight joint is connected with a plunger-type cylinder and the other end of the double-head straight joint is connected with the high-pressure metal hose; the other end of the high-pressure metal hose is communicated with a flange disc and the two ends of the high-pressure metal hose are all provided with metal wound sealing gaskets. The utility model overcomes the defects of a traditional pipeline joint and a sealing way and scientifically overcomes the defects of a hydraulic pipeline and a joint seal, so as to radically solve high-pressure oil leakage faults, improve the safety performance of equipment and reduce the production cost. In the utility model, the high-pressure metal hose is used for replacing a previous seamless steel pipe to solve the problems of frequently damaging sealing components due to seriously movement of a high-pressure pipeline in an axial direction and a radial direction, thereby realizing the aims of greatly improving the production efficiency, saving energy and reducing consumption.
Description
Technical field:
The utility model relates to a kind of joint connection, particularly relates to a kind of joint and connects seal arrangement.
Background technique:
The main body manufacturing mechanism of assembly room returns workshop section; Because the defective that its plunger case off-load pipe joint connects and sealing means designs, makes; Pressure moment is reduced to 0Mpa rapidly and the string that produces is moving from 15Mpa when adding off-load; Caused since main body manufacturing mechanism to the operation, plunger case off-load pipe joint connects sealing part and exists serious seepage effectively to solve always.And under high pressure conditions, the hydraulic oil seepage just can reach more than 170 kilogram in the moment of finding, in order to produce needs, must constantly replenish new hydraulic oil, and therefore waste is very serious.And receive the restriction of off-load pipe mounting point, jointing seal defect, make that the manufacturing mechanism running rate is low, the cost of overhaul is higher, and the environmental pollution that hydraulic fluid leak caused is serious.
The model utility content:
The utility model technical problem to be solved is: the deficiency that overcomes existing technology; Provide a kind of modern design, scientific and reliable joint to connect seal arrangement; Avoid hydraulic fluid leak, hydraulic tubing string to move to greatest extent; Avoid the damage of solenoid valve and the pollution of environment, increase substantially manufacturing efficiency and energy saving purposes thereby reach.
The utility model is that the technological scheme that the technical solution problem is taked is:
A kind of joint connects seal arrangement; Comprise double end straight coupling and high-pressure metal flexible pipe; One end of said double end straight coupling is connected with plunger case, and the other end is connected with the high-pressure metal flexible pipe through the buckle nut, and the other end of said high-pressure metal flexible pipe and flange plate are communicated with.
The two ends of described high-pressure metal flexible pipe are provided with metal and twine sealing gasket.
The cross section at said double end straight coupling two ends is the cambered surface seal form.
The good effect of the utility model is:
1, the utility model has solved the defective of former pipe joint and sealing means, scientifically hydraulic tubing and joint sealing defective is effected a radical cure, thereby has effected a radical cure the high pressure oil leakage failure, has improved device ', enhances productivity, and reduces production costs.
2, the utility model has solved the axial of high pressure pipe line and the moving Sealing frequent breakage that is caused of serious string radially owing to used the high-pressure metal flexible pipe to replace former seamless steel pipe.
3, the utility model is simple in structure, easy to process, under the support of existing mechanical technology, realizes having market prospects easily.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Referring to Fig. 1, wherein: 1---double end straight coupling, 2---buckle nut, 3---high-pressure metal flexible pipe, the 4---flange plate, the 5---metal twines sealing gasket.
Embodiment: a kind of joint connects seal arrangement; Comprise double end straight coupling 1 and high-pressure metal flexible pipe 3; One end of said double end straight coupling 1 is connected with plunger case, and the other end is connected with high-pressure metal flexible pipe 3 through buckle nut 2, and the other end of said high-pressure metal flexible pipe 3 and flange plate 4 are communicated with; The two ends of described high-pressure metal flexible pipe 3 are provided with metal and twine sealing gasket 5; The cross section at said double end straight coupling 1 two ends is the cambered surface seal form.
The cross section at the double end straight coupling two ends of the utility model is the cambered surface seal form, and the screw thread that is used to install forms a kind of seal form, and such double-sealing performance is safe and reliable.And replace former seamless steel pipe with the high-pressure metal flexible pipe, discharged the high pressure action string power of pipeline down, guaranteed sealability.
