Abstract
The invention discloses a U-shaped pipe pressure test fixture used in an alkylation reactor. The fixture realizes U-shaped pipe single-tube pressure testing or linkage pressure testing without temporary welding and comprises a fixture joint, a locknut, an O-shaped sealing ring, a taper sealing sleeve chuck and a taper fastening sleeve chuck. The purpose of pressure testing is realized through pressurization of the fixture joint. The U-shaped pipe pressure test fixture used in the alkylation reactor can also be applied to pressure testing and measurement of other equipment with test pressure of less than 2.4 MPa.
Description
Technical field
The invention belongs to manometric technique field, be specifically related to the U-shaped pipe pressure testing jig in a kind of alkylation reactor, also can be applied to the pressure testing that test pressure is less than the U-shaped pipe of other equipment of 2.4MPa simultaneously.
Background technology
In the U-shaped pipe manufacturer of alkylation reactor, due to the singularity of its stringing, need be before assembling tube bank, each U-shaped pipe is not less than to the hydraulic testing of 2 times of design pressures, check that tubing, open joint and brake forming section have the gentle hole of flawless etc. to run through type defect, guarantee intensity and the tightness of U-shaped pipe.Otherwise, if find to leak in the time of final alkylation reactor pressure test, just cannot remedy.Therefore, the pressure testing of U-shaped pipe is a critical process that guarantees product quality.
Conventional Pressure test program is that one section of U-shaped pipe single tube is welded with jam, and the other end welds screwed tubule, and then carries out pressure testing, after pressure measurement finishes, then carries out gas cutting separation, completes the pressure testing process of one group of U-shaped pipe with this.Such pressure-measuring method, has added a procedure, has caused the waste of manpower and materials, and labour intensity increases, and welding material waste is serious, efficiency step-down.
Summary of the invention
The present invention is intended to address the above problem, and a kind of U-shaped pipe pressure testing jig of simple in structure, low cost of manufacture is provided, and has good airproof performance, is suitable for that pressure is high, labour intensity is low, work efficiency high.
The U-shaped pipe pressure testing of one provided by the invention jig, comprises jig joint, set nut, O RunddichtringO, cone seal cutting ferrule, the fastening cutting ferrule of taper.The two ends, left and right of jig center tap body are with external thread, in joint body, be provided with stepped hole, the left part of set nut has threaded hole, right part has circular hole, and threaded hole is communicated with circular hole, the right-hand member of threaded hole and joint body links together, and O-ring seals, cone seal cutting ferrule and the fastening cutting ferrule of taper are equipped with in inner conical surface place, and the fastening cutting ferrule of cone seal cutting ferrule and taper is fixed by the conical surface.
Jig is easy and simple to handle, and convenient disassembly has not only been saved wlding, goes back linkage pressure testing, i.e. many U-shaped pipes of a pressure testing, and work efficiency improves more than 10 times.Concrete operations are that U-shaped tube end is filled in to jig, rotational lock nut, and the fastening cutting ferrule of taper promotes cone seal cutting ferrule, and extruding O-ring seals tightly blocks U-shaped pipe, then passes through the supercharging of jig joint, thereby reaches the object of pressure testing.
Accompanying drawing explanation
Accompanying drawing 1 is the U-shaped pipe pressure testing jig schematic diagram for alkylation reactor, its concrete digital implication respectively: 1. jig joint; 2.U shape pipe; 3. set nut; 4.O RunddichtringO; 5. cone seal cutting ferrule; 6. the fastening cutting ferrule of taper.
Embodiment
U-shaped pipe pressure testing jig is mainly by jig joint, set nut, and O RunddichtringO, cone seal cutting ferrule, the fastening cutting ferrule of taper form.
The two ends, left and right of jig center tap body are with external thread, in joint body, be provided with stepped hole, the left part of set nut has threaded hole, right part has circular hole, and threaded hole is communicated with circular hole, the right-hand member of threaded hole and joint body links together, and O-ring seals, cone seal cutting ferrule and the fastening cutting ferrule of taper are equipped with in inner conical surface place, and the fastening cutting ferrule of cone seal cutting ferrule and taper is fixed by the conical surface.
Concrete operations are that U-shaped tube end is filled in to jig, rotational lock nut, and the fastening cutting ferrule of taper promotes cone seal cutting ferrule, and extruding O-ring seals tightly blocks U-shaped pipe, then passes through the supercharging of jig joint, thereby reaches the object of pressure testing.
By test, this jig can bear the not pressure higher than 2.4MPa and carry out the hydraulic testing, and the design pressure of alkylation reactor is 0.78MPa, and this jig can meet the requirement of the pressure testing of alkylation reactor single tube completely.
Claims (2)
1. the U-shaped pipe pressure testing jig for alkylation reactor, it is characterized in that without using interim welding can reach the object of the pressure testing of U-shaped pipe single tube or interlock pressure testing, jig comprises jig joint, set nut, O RunddichtringO, cone seal cutting ferrule, fastening cutting ferrule five parts of taper, the two ends, left and right of described jig center tap body are with external thread, in joint body, be provided with stepped hole, the left part of set nut has threaded hole, right part has circular hole, and threaded hole is communicated with circular hole, the right-hand member of threaded hole and joint body links together, there is O-ring seals at inner conical surface place, the fastening cutting ferrule of cone seal cutting ferrule and taper, the fastening cutting ferrule of cone seal cutting ferrule and taper is fixed by the conical surface.
2. a kind of U-shaped pipe pressure testing jig for alkylation reactor according to claim 1, is characterized in that jig joint contains supercharging, pressure measurement instrument.
