Description
Technical field
The utility model relates to a kind of tool structure, belongs to heat exchanger tube checkout equipment field, is specifically related to a kind of tool structure for single tube pressure testing.
Background technology
Heat exchanger tube be current oil, chemical industry heat interchanger main pressurized without part.Occur leaking for preventing assembling rear pipe body, before carrying out assembling, the single hydraulic testing is very important.
Traditional heat exchanger tube test adopts welding joint method, and structure as shown in Figure 1.Its end sealing relies on Site Welding closure plate to complete, and often completes a pipe and must cut open closure plate and again be soldered to another root two ends.This scheme is time-consuming takes material, and needs to cut away closure plate and cause heat exchanger tube to shorten after completion.The equipment large on device diameters, heat exchanger tube quantity is many is very inconvenient and affect manufacturing schedule.
Utility model content
The utility model mainly solves the single tube pressure testing inefficiency existing for prior art, the technical matters that manufacturing schedule is slow; Provide a kind of tool structure for single tube pressure testing.This structure have employed lifting jack fast-holding pressure testing pipe, substantially reduces the pressure testing cycle, improves pressure testing efficiency.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of tool structure for single tube pressure testing, comprise: the inlet damper be oppositely arranged and guard rails, this inlet damper and guard rails are respectively arranged with for inserting and the inlet damper groove of fixation test tube end and guard rails groove, be provided with a water inlet in described inlet damper groove, the top of the one side and lifting jack that described guard rails are not arranged guard rails groove connects.
Optimize, above-mentioned a kind of tool structure for single tube pressure testing, described water inlet is connected with tensimeter with inlet valve.
Optimize, above-mentioned a kind of tool structure for single tube pressure testing, is provided with an O-ring seal in described inlet damper groove.
Optimize, above-mentioned a kind of tool structure for single tube pressure testing, also comprise several and be placed on location-plate on described developmental tube, described location-plate is provided with register pin.
Optimize, above-mentioned a kind of tool structure for single tube pressure testing, the bottom of described lifting jack is fixed on force bearing plate.
Therefore, the utility model tool has the following advantages: (1) seals reliable, easy to use; (2) improve product quality, shorten the duration.
Accompanying drawing explanation
Fig. 1 is structure for pressure test structural representation of the prior art.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.In figure, inlet valve 1, straight joint 2, tensimeter 3, flexible pipe 4, fast joint 5, inlet damper 6, O-ring seal 7, developmental tube 8, location-plate 9, register pin 10, guard rails 11, lifting jack 12, force bearing plate 13, inlet damper groove 14, guard rails groove 15, water inlet 16.
Embodiment:
As shown in Figure 1, a kind of tool structure for single tube pressure testing, comprise: the inlet damper 6 be oppositely arranged and guard rails 11, this inlet damper 6 and guard rails 11 are respectively arranged with for inserting and the inlet damper groove 14 of fixation test pipe 8 end and guard rails groove 15, be provided with a water inlet 16 in inlet damper groove 14, this water inlet 16 is connected with tensimeter 3 with inlet valve 1.Be provided with an O-ring seal 7 in this inlet damper groove 14, flow out from interface for anti-sealing.One side guard rails 11 not being arranged guard rails groove 15 connects with the top of lifting jack 12, and the bottom of lifting jack 12 is fixed on force bearing plate 13.Developmental tube also has several location-plates 9, this location-plate 9 is provided with register pin 10.
After adopting said structure, before the hydraulic testing, inlet damper 6 is inserted in developmental tube 8 one end, and end adds O-ring seal 7, and the other end inserts the guard rails 11 of band O-ring seal, then inserts register pin 10 at location-plate 9.Quick startup tailjack 12, after being sealed by developmental tube 8, opens water intaking valve 1, when pressure rises to test pressure, and valve-off 1.Observation tensimeter 3 changes and check test pipe has ne-leakage or abnormal voice, and after stand the test, rapid resilience lifting jack 12, pull-out register pin 9, takes off developmental tube 8, separately change one and repeat above process.
Single tube structure for pressure test after improvement has sealing feature reliable, easy to use, by using this frock, ensure that product quality, shortening the duration, obtain the consistent affirmative of user.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as inlet valve 1, straight joint 2, tensimeter 3, flexible pipe 4, fast joint 5, inlet damper 7, developmental tube 8, location-plate 9, register pin 10, guard rails 11, lifting jack 12, force bearing plate 13 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
