Abstract
The utility model provides a low-temperature cable seal joint and relates to the field of power line seal. The low-temperature cable seal joint comprises an internal fixing and clamping member (1), a first support member (2), a seal member (3), a second support member (4), a rotary locating member (5) and an external rotary clamping member (6). The first support member (2), the seal member (3), the second support member (4) and the rotary locating member (5) are disposed in the internal fixing and clamping member (1); the external rotary clamping member (6) is connected with the internal fixing and clamping member (1) in a sleeving manner and is in threaded connection with the internal fixing and clamping member (1) on the outer side thereof; the first support member (2) is connected with the seal member (3) which is connected with the second support member (4); and the outer side of the second support member is provided with the rotary locating member (5). The low-temperature cable seal joint is made of material characterized by low temperature resistance and electric insulation performance and used for sealing and thus is characterized by seal performance, low temperature resistance and electric insulation performance, and is simple to process, reasonable in design, easy to use, highly practical and easy to promote and use.
Description
Technical field
The utility model relates to the power line field of sealing technology, is specifically related to a kind of cryocable seal nipple.
Background technology
Because requirements of one's work, low temperature immersed pump need power supply when working in low temperature, Pressure Vessel, therefore need to solve sealing and the isolating problem of cable.But domestic not relevant product parts, thus need to be from external import, and not only price is higher but also difficulty of processing is very large for the commodity of import, thereby has improved cost.
Summary of the invention
The purpose of this utility model provides a kind of cryocable seal nipple, and the materials processing that its adopts low temperature resistant, electric insulation, can seal forms, thereby can possess simultaneously sealing, characteristic and processing method low temperature resistant, electric insulation are simple.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises interior fixed clamping piece 1, the first strutting piece 2, seal 3, the second strutting piece 4, rotatable positioning member 5 and inner rotary clamping element 6; The inside of interior fixed clamping piece 1 arranges the first strutting piece 2, seal 3, the second strutting piece 4 and rotatable positioning member 5, inner rotary clamping element 6 is spirally connected with interior fixed clamping piece 1 relative socket and in its outside, the first strutting piece 2 connection sealing elements 3, the arranged outside that seal 3 connects the second strutting piece 4, the second strutting pieces 4 has rotatable positioning member 5.
Interior fixed clamping piece 1 under the test that is sealed in 2MPa between the inner rotary clamping element 6 without leakage phenomenon.
The first strutting piece 2, seal 3 and the second strutting piece 4 are provided with aperture and the hole count that is complementary with the low-temperature insulation cable.
Operation principle: the utility model product parts all can work under low temperature condition, many low-temperature insulation cables pass the first strutting piece 2 in order, seal 3, the hole of the second strutting piece 4 correspondences, rotation inner rotary clamping element 6, distance between interior fixed clamping piece 1 and the inner rotary clamping element 6 can diminish along with the rotation of screw thread, deformation occurs cable is formed sealing in seal 3 under the clamping of the first strutting piece 2 and the second strutting piece 4, deformation and the 1 formation sealing of interior fixed clamping piece occur in seal 3 simultaneously, have so just formed interior fixed clamping piece 1 to the sealing of inner rotary clamping element 6.
That the utility model adopts is low temperature resistant, electric insulation, the materials processing that can seal form, thereby can possess simultaneously sealing, characteristic and processing method low temperature resistant, electric insulation are simple, reasonable in design, easy to use, practical, is easy to promote and use.
Description of drawings:
Fig. 1 is cross section view of the present utility model.
Embodiment:
With reference to Fig. 1, this embodiment by the following technical solutions: it comprises interior fixed clamping piece 1, the first strutting piece 2, seal 3, the second strutting piece 4, rotatable positioning member 5 and inner rotary clamping element 6; The inside of interior fixed clamping piece 1 arranges the first strutting piece 2, seal 3, the second strutting piece 4 and rotatable positioning member 5, inner rotary clamping element 6 is spirally connected with interior fixed clamping piece 1 relative socket and in its outside, the first strutting piece 2 connection sealing elements 3, the arranged outside that seal 3 connects the second strutting piece 4, the second strutting pieces 4 has rotatable positioning member 5.
Interior fixed clamping piece 1 under the test that is sealed in 2MPa between the inner rotary clamping element 6 without leakage phenomenon.
The first strutting piece 2, seal 3 and the second strutting piece 4 are provided with aperture and the hole count that is complementary with the low-temperature insulation cable.
Operation principle: the utility model product parts all can work under low temperature condition, many low-temperature insulation cables pass the first strutting piece 2 in order, seal 3, the hole of the second strutting piece 4 correspondences, rotation inner rotary clamping element 6, distance between interior fixed clamping piece 1 and the inner rotary clamping element 6 can diminish along with the rotation of screw thread, deformation occurs cable is formed sealing in seal 3 under the clamping of the first strutting piece 2 and the second strutting piece 4, deformation and the 1 formation sealing of interior fixed clamping piece occur in seal 3 simultaneously, have so just formed interior fixed clamping piece 1 to the sealing of inner rotary clamping element 6.
That this embodiment adopts is low temperature resistant, electric insulation, the materials processing that can seal form, thereby can possess simultaneously sealing, characteristic and processing method low temperature resistant, electric insulation are simple, reasonable in design, easy to use, practical, be easy to promote and use.
