Abstract
It the utility model is related to instrumentation pipeline connection area, disclose particularly a kind of test splice, including joint body and adjusting nut, the joint body includes the seal shaft coordinated with the sealing hole of the adjusting nut, seal is provided between the seal shaft and the sealing hole, and the seal being arranged between adjusting nut seal face and tested product the interface end face.The utility model is convenient and fast connection, without winding raw material band, greatly improves the operating efficiency of test jobs, joint design is light and handy, and manufacturing cost is low.
Description
Technical field
Instrumentation pipeline connection area is the utility model is related to, relates more specifically to a kind of test splice.
Background technology
, it is necessary to can shipment by pressure test after finished product be made in valve and complete pipe fitting.Valve pipe fitting is surveyed in pressure
, it is necessary to which some interfaces and pressure source of product are connected during examination, the interface shape of currently used valves and fittings is cone
Screw thread., it is necessary to be linked up product interface with pressure source with the joint of taper thread during test.Taper thread connection is usually required in sun
Upper raw material band is wound on screw thread, and joint is tightened according to corresponding torque, to ensure that connection is reliable.Winding raw material band takes very much manually
Time, reduce the testing efficiency of product；After test terminates in addition, raw material can be bonded on negative thread with part, before packaging, made
Special messenger is wanted to clear up；Furthermore raw material band is also disposable, often connecting once needs to rewind a raw material band, waste of materials.
Therefore, it is necessary to a kind of new test splice, to solve the above problems.
Utility model content
According to the deficiencies in the prior art, the utility model provides a kind of test splice, including joint body, adjusting nut,
Characterized in that, have in the middle part of the joint body one be used for clamp six sides, six side, one section of external screw thread of adjoining is described
The seal shaft that external screw thread adjacent one radially reduces, is provided with annular groove on the seal shaft.The adjusting nut includes one
Female thread portion, a sealing hole and a seal face, the regulation spiral shell engage with the joint body screw thread, the sealing
Hole coordinates with the seal shaft, and when the joint is connected with tested product interface port, the adjusting nut can rotate to
Seal face is bonded with the tested product interface end face.
Preferably, the seal face and the sealing hole are provided with sealing by a concave transition in the depression
Part.
Preferably, it is provided with seal in the annular groove.The seal in the adjusting nut rotary course,
All the time it is maintained in the groove.
The beneficial effects of the utility model are：
1st, without winding raw material band and using specific purpose tool, improving the operating efficiency of test jobs.
2nd, using repeatable practical seal, material is saved.
3rd, design is easy to use, and manufacturing cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of the pressure test tap comprising the utility model design；
Embodiment
For the ease of the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.
Reference picture 1, the test splice include joint body 16, adjusting nut 22, and joint body 16 has one to be located at
Six sides 26 in portion, when joint installs or removes, six sides 26 can be used for clamping or anchor tip.The left end 32 of six sides 26 is used to connect
Source of the gas end is connect, connected mode is optional, and in the present embodiment, 32 be the end of thread.The adjacent one end straight thread 28 in the right side of six side 26 is adjacent
Straight thread 28 has a seal shaft 56 radially reduced, the screw thread for extending a connecting test product port 42 of seal shaft 56
Connection end 38.
Adjusting nut 22 has a female thread portion 34 engaged with the joint body straight thread 28, and with the seal shaft 56
The sealing hole 58 of cooperation, annular external groove 18 is provided with seal shaft 56, seal 36 is positioned in groove 18.
Adjusting nut 22 also includes the seal face 52 being bonded with test product interface end face 46, seal face 52 and sealing
Connected between hole 58 by 24 transition that are recessed, seal 20 is provided with depression 24, when seal face 52 connects with tested product
When mouth end face 46 is bonded, the seal 36 is maintained in groove 18 by sealing hole 58.
It is of the present utility model to be using step；Seal 36 is arranged in the groove 18 of joint body 16, regulation spiral shell
Mother 22 from joint body 16 screw in until joint body right-hand member 38 be completely exposed, then by seal 20 be put into adjusting nut be recessed 24
It is interior.Joint body 16 is turned, right-hand member 38 is connected with tested product interface 42, then rotating adjusting nut 22, makes regulation spiral shell
Female seal face 52 is bonded with tested product interface end face 46.
The utility model is described by reference to preferred embodiment, and the content mentioned in above-described embodiment is not
To restriction of the present utility model, by reading this specification, those skilled in the art can go out the modification of many to the structural framing
And change, it is without departing from the concept of the premise utility, any obviously to replace in protection of the present utility model
Within the scope of.
Claims (3)
