Description
Technical field
This utility model relates to a kind of pipe safety device, specifically, relates to a kind of compound compensator of bidirectional guide.
Background technology
The version of pipeline compensator is varied, has single entry type, compound type, equilibrated type etc., compound type compensator
It is typically all and is connected by corrugated tube by between middle adapter with two ends pipe nipple, constitute compound compensator.Existing compound compensation
Being provided with the mozzle axially covering corrugated tube in the corrugated tube of device, mozzle set-up mode is along pipeline at the corrugated tube of two ends
Medium flows to respectively arrange a mozzle, although this setup can guide medium to circulate effectively, but there is defect:
In two mozzles in a middle adapter to be welded on, middle adapter has the longest distance outside pipe nipple, work during welding
Skill is poor；When pipeline medium has granular substance, granular substance enters corrugated tube from the gap location of mozzle with adapter endoporus
Inner chamber, corrugated tube lost efficacy because solid particle scratches, had a strong impact on service life.
Summary of the invention
This utility model for the deficiencies in the prior art, proposes a kind of to solve asking of mozzle welding usability difference
Topic, the granular substance that is avoided that again in medium enters corrugated tube inner chamber, and the notable bidirectional guide extending compensator service life is multiple
Formula compensator.
This utility model is achieved through the following technical solutions technical goal.
The compound compensator of bidirectional guide, including pipe nipple, corrugated tube, left mozzle, middle adapter, right mozzle, described
It is connected by corrugated tube between middle adapter with two ends pipe nipple, constitutes complex corrugated pipe collocation structure；Set in described corrugated tube
Have and axially cover the left mozzle of corrugated tube and right mozzle；It thes improvement is that: described left mozzle, right mozzle are relative
Setting up, the left end of left mozzle is fixedly connected on the inwall of left-hand end adapter, and the right-hand member of right mozzle is fixedly connected on right-hand end
The inwall of adapter, the right-hand member of left mozzle, the left end fit of right mozzle, suit place is provided with sealing structure.
In said structure, the sealing structure of described left mozzle and right mozzle suit place is labyrinth seal structure.
In said structure, the right-hand member of described left mozzle is provided with in-flanges, and the left end of right mozzle is provided with flanging；Described
Left mozzle right-hand member in-flanges and right mozzle left end flanging gap fit, constitute labyrinth seal structure.
This utility model compared with prior art, has the positive effect that:
The most left mozzle, right mozzle are set up relatively, and the left end of left guide shell is fixedly connected on the inwall of left-hand end adapter,
The right-hand member of right guide shell is fixedly connected on the inwall of right-hand end adapter, significantly improves welding technological properties, reduces cost of manufacture；Left
The sealing structure of flanging in right mozzle, it is not necessary to increase other encapsulants, significantly reduce production cost；Left and right flow-directing shroud
Also there is after conjunction protection compensator corrugated tube in extreme cases be not straightened and lost efficacy.
2. labyrinth seal structure protects corrugated tube not to be etched effectively, improves the service life of corrugated tube, thus enters
One step extends compound compensator service life, reduces use cost.
3. compensator is not flowed to be affected by medium when installing, easy for installation.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is I part partial enlarged drawing in Fig. 1.
Detailed description of the invention
Below according to accompanying drawing and the utility model is described in further detail in conjunction with the embodiments.
The compound compensator of bidirectional guide shown in the drawings, including pipe nipple 1, corrugated tube 2, left mozzle 3, middle adapter 4,
Right mozzle 5, is connected by corrugated tube 2 between middle adapter 4 with two ends pipe nipple 1, constitutes complex corrugated pipe compensator structure；
Left mozzle 3 and the right mozzle 5 axially covering corrugated tube 2 it is provided with in corrugated tube 2；In the present embodiment, left mozzle 3, the right side are led
Flow tube 5 is set up relatively, and the left end of left mozzle 3 is fixedly connected on the inwall of left-hand end adapter 1, and the right-hand member of right mozzle 5 is fixed
Being connected to the inwall of right-hand end adapter 1, the right-hand member of left mozzle 3 is provided with in-flanges, and the left end of right mozzle 5 is provided with flanging；
Left mozzle 3 right-hand member in-flanges and right mozzle 5 left end flanging gap fit, constitute labyrinth seal structure, both to ripple
The inner chamber of pipe 2 effectively seals protection, has again protection compensator corrugated tube 2 in extreme cases and is not straightened and lost efficacy.
