Abstract
The utility model overcomes the shortcomings of the prior art, provide a kind of seal nipple of pressure adjustable, it may insure that joint seals and can tolerate certain pressure, Reagent Tube fixation is difficult for drop-off, and is not in phenomena such as Reagent Tube is obstructed in use；In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of seal nipple of pressure adjustable, including Reagent Tube, pressure head, pressure pad, O-ring and undertaking body, one end end set of the Reagent Tube has flange, the pressure head, pressure pad and O-ring are sleeved in reagent pipe outer wall successively, the pressure head is correspondingly inserted into undertaking body, and the grafting depth by adjusting pressure head and undertaking body controls the pressure between O-ring and flange；The utility model can be widely applied to water quality monitor field.
Description
Technical field
A kind of seal nipple of pressure adjustable of the utility model, belongs to water quality monitor technical field.
Background technology
Water quality monitor conveys various reagents by Reagent Tube, and its joint need to meet seal request and resistance to pressure request simultaneously.
The consequence that leakage may be brought has：Measurement result skew, damage monitoring instrument, to operator bring injury.
The joint in water quality monitor realizes sealing using cone sealing more at present, is realized using the deformation of Reagent Tube resistance to
Pressure, but its sealing effectiveness and pressure-resistant effect are all not satisfactory.When sealing force is smaller, its Reagent Tube can take off under less power
Fall；When sealing force is big, the excessive deformation of Reagent Tube can cause Reagent Tube obstructed.
Utility model content
The utility model overcomes the shortcomings of the prior art, there is provided a kind of seal nipple of pressure adjustable, can be with
Ensure that joint seals and can tolerate certain pressure, Reagent Tube fixation is difficult for drop-off, and will not go out in use
Phenomena such as now Reagent Tube is obstructed.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of sealing of pressure adjustable connects
Head, including Reagent Tube, pressure head, pressure pad, O-ring and undertaking body, one end end set of the Reagent Tube have flange, the pressure
Head, pressure pad and O-ring are sleeved in reagent pipe outer wall successively, and the pressure head is correspondingly inserted into undertaking body, by adjusting pressure head
The pressure between O-ring and flange is controlled with the grafting depth of undertaking body.
The undertaking body end is in hollow stepped, the corresponding insertion undertaking of the Reagent Tube, pressure head, pressure pad and O-ring
The end of body, the cavity between the O-ring and undertaking body are undertaking unthreaded hole section.
The undertaking body passes through grafting depth of the threaded adjusting pressure head in undertaking body end with pressure head.
The both ends of the Reagent Tube are provided with flange.
The utility model has an advantageous effect in that compared with prior art：The utility model can simply realize joint
Sealing, and tolerable certain pressure, and because of the increase of proof pressure Reagent Tube will not be caused obstructed.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1 be Reagent Tube, 2 be pressure head, 3 be pressure pad, 4 be O-ring, 5 be undertaking body, 6 be flange, 7 be accept unthreaded hole
Section, 8 are screw thread.
Embodiment
As shown in figure 1, a kind of seal nipple of pressure adjustable of the utility model, including Reagent Tube 1, pressure head 2, pressure pad 3, O
Type circle 4 and undertaking body 5, one end end set of the Reagent Tube 1 have flange 6, and the pressure head 2, pressure pad 3 and O-ring 4 cover successively
On the outer wall of Reagent Tube 1, the pressure head 2 is corresponding to be inserted into undertaking body 5, is indulged by adjusting pressure head 2 and the grafting of undertaking body 5
Pressure between deep control O-ring 4 and flange 6.
The end of undertaking body 5 is in hollow stepped, the corresponding insertion of the Reagent Tube 1, pressure head 2, pressure pad 3 and O-ring 4
The end of undertaking body 5, the cavity between the O-ring 4 and undertaking body 5 are undertaking unthreaded hole section 7.
The undertaking body 5 adjusts grafting depth of the pressure head 2 in the end of undertaking body 5 with pressure head 2 by screw thread 8.
The both ends of the Reagent Tube 1 are provided with flange 6.
Operation principle of the present utility model：The end of Reagent Tube 1 flanged 6 in the utility model, by O-ring 4, pressure pad 3, pressure
First 2 are set on Reagent Tube 1 successively, O-ring 4 is located among flange 6 and pressure pad 3., will when pressure head 2 is rotatably connected in undertaking body 5
Pressure pad 3, O-ring 4, Reagent Tube 1 have been again secured in undertaking body 5.Pressure head 2 is screwed, O-ring 4 deforms under stress, and its outside is tight
The inwall of undertaking body 5 is affixed on, the wall of Reagent Tube 1 is close in inner side, so as to realize sealing.Because flange 6 is contained in the end of Reagent Tube 1, because
This Reagent Tube 1 is difficult for drop-off；The presence of flange 6 also enhances the rigidity of Reagent Tube 1 simultaneously, Reagent Tube 1 is not easy in O-ring 4
Extruding is lower to produce deformation, so as to ensure that the unimpeded of Reagent Tube.
The course of work of the present utility model：The receiving hole of the utility model undertaking body 5 includes two sections, accepts unthreaded hole section 7 and holds
Screw thread hole section is connect, flange 6, O-ring 4, the pressure pad 3 of the end of Reagent Tube 1, which are extend into, accepts unthreaded hole section 7, and pressure head 2, which screws in, accepts screw thread
Hole section, and the leading portion of pressure head 2 is pressed onto on pressure pad 3.Continue to screw in pressure head 2, O-ring 4 produces deformation under stress, and its inner side is close to
Reagent Tube 1, outside, which is close to, accepts unthreaded hole section 7, realizes sealing.O-ring 4 can be prevented damaged under extrusion for pressure pad 3 or fracture, together
When pressure pad 3 can prevent from driving O-ring 4 and the special concomitant rotation of Reagent Tube 1 when pressure head 2 screws in.When poor sealing, continue
Sealing effectiveness can be improved by screwing in pressure head 2.In addition, flange 6 can prevent Reagent Tube 1 from coming off, and Contrast agent pipe 1 connects with O-ring 4
Touch the rigidity of sealing position.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in those of ordinary skill in the art's possessed knowledge, the utility model aims can also not departed from
On the premise of various changes can be made.
