Description
Technical field
The utility model relates to joint field, particularly relates to a kind of hand-wring type butt joint.
Background technique
Butt joint is used for connecting fast between flexible pipe, is communicated with the pipeline such as gas, liquid, is widely used in the every field in productive life.But existing butt joint is not do not have auto-lock function, is exactly that sealing effect is general, is particularly useful for the low pressure gas circuit that required precision is higher, as the gas circuit under 2.5KPa air pressure, often occurs micro-leakage, affect test result.
Model utility content
The utility model is not do not have auto-lock function in order to the butt joint solved in the market, is exactly the general problem of sealing effect, proposes a kind of hand-wring type butt joint with auto-lock function, good sealing effect.
To achieve these goals, the utility model is by the following technical solutions: a kind of hand-wring type butt joint, male and female, described male is axially followed successively by tracheae joint, screws portion and male end-to-end joint part, male axis runs through and has vent, be provided with outside thread outside described male end-to-end joint part, end face is provided with boss, and boss is provided with breach; Described female is axially followed successively by tracheae joint, screws portion and female end-to-end joint part, female axis also runs through and has vent, described female end-to-end joint part end face is provided with the internal thread mated with male end-to-end joint part outside thread, be provided with sealing cover inside internal thread, sealing cover is by spring compresses shutoff screw mouth; Described male and the portion of screwing of female are all provided with the ear mechanism be convenient to hand and twisted.
As preferably, inside described spring, be provided with the retaining post of sealing cover.
As preferably, described tracheae attachment portion is nut joint, input termination and nut, and described nut joint connects valve body and input termination, and nut joint is provided with the outside thread mated with nut, and described input end head portion is taper.
As preferably, sealing cover material is silica gel.
Therefore, the utility model has following beneficial effect: (1) has auto-lock function, low pressure seal is effective; (2) adopt thread mechanism docking, connect reliable; (3) portion of screwing of male and female is all provided with ear mechanism, both twists by spanner, also can twist by hand.
