Abstract
The invention relates to a novel sulfur hexafluoride gas micro-water test leak-proof joint and belongs to the field of connecting devices. A sulphur hexafluoride circuit breakers gas moisture test is one of detection means so as to ensure the safe operation of the device, the test has high requirement on the sealability of the gas pipeline joint, and most of the existing joint forms can not meet the requirement and have high possibility of deformation and air leakage after long time using, thereby influencing the accuracy of the measurement and the personal safety of testing staffs, and polluting the environment. The connecting part of joint is improved, the above problem is solved by changing the cylindrical shape into the hydraucone shape, and the leakage phenomenon is not discovered through leak hunting. The leak-proof joint provided by the invention has the advantages that the process cost is cheap, the use is convenient, the joint is easy to popularize to the direct production, and the leak-proof joint is also a simple means for effect improvement in the sulfur hexafluoride gas on-site detecting work.
Description
Technical field
The present invention relates to a kind of joint form, especially a kind of sulfur hexafluoride breaker gas moisture measurement joint form.
Background technique
Sulfur hexafluoride breaker gas moisture measurement is one of detection means that guarantees equipment safety operation, this test has very high requirement to gas pipeline joint sealing, the general joint form that generally adopts is difficult to meet the demands mostly now, after long-term the use, also be prone to the problem of distortion gas leakage, thereby influence accuracy and tester's personal safety of measuring, and environment is polluted.
Summary of the invention
The technical problem to be solved in the present invention is the defective that overcomes prior art, provides a kind of novel sulfur hexafluoride gas little water test leakproof joint.
In order to solve the problems of the technologies described above, the invention provides following technological scheme:
The little water test leakproof joint of a kind of novel sulfur hexafluoride gas is made up of joint head body and joint joint two-part, and described joint joint is bell mouth shape.
As preferably, described joint joint is made up of horn mouth overlay cladding and internal connection joint.
The present invention makes it compared with prior art owing to adopted above technological scheme, has the following advantages and characteristics:
1. after transforming, hunt leak with leak detector butt joint place when the little water of sulfur hexafluoride gas is tested, do not find the seepage situation, improve a lot through improved joint tighness.
2. with low cost, easy to use, be easy to promote.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification, is used from explanation the present invention with embodiments of the invention one, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is a surface structure schematic representation of the present invention,
Fig. 2 dissects structural representation for joint of the present invention joint.
The title of each label is as follows among the figure: 1-joint head body, 2-overlay cladding, 3-joint joint, 4-internal connection joint.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Embodiment one
As shown in Figure 1, the little water test leakproof joint of a kind of novel sulfur hexafluoride gas is made up of joint head body 1 and joint joint 3 two-part, and joint joint 3 is bell mouth shape.
Embodiment two
Ordinary couplings joint joint is similar cylindric in the test of sulfur hexafluoride breaker gas moisture measurement, there is obvious space in the joint joint when being connected with pipeline junction, easily cause sulfur hexafluoride gas to leak in the test, stability, accuracy to experimental test have considerable influence, cause unsafe factors such as environmental pollution and harm tester health of human body simultaneously.
As shown in Figure 2, now this ordinary couplings is transformed, with this ordinary couplings joint joint as internal connection joint 4, utilize welding process to transform internal connection joint 4, with 0# sand paper internal connection joint 4 is handled earlier, smear with solder flux cream then, carry out built-up welding again and form overlay cladding 2, in the weld deposit process joint joint is rotated roughly to reach bell mouth shape, earlier with the file polishing, form the horn mouth shape of the joint joint 3 that requires then with sand papering after cooling.
It should be noted that at last: the above only is the explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. the little water test leakproof joint of novel sulfur hexafluoride gas is made up of joint head body and joint joint two-part, and it is characterized in that: described joint joint is bell mouth shape.
2. the little water test leakproof joint of a kind of novel sulfur hexafluoride gas according to claim 1, it is characterized in that: described joint joint is made up of horn mouth overlay cladding and internal connection joint.
