Description
Technical field
the utility model relates to gas drilling elbow technical field, is a kind of erosion resistance elbow for gas drilling.
Background technology
elbow is used frequently in gas drilling operation, thickening process is carried out to the break-in link of 120 degree and the 150 degree elbows in the application of gas drilling scene, its abrasion resistance strengthens, service time lengthens, but the type elbow is using the phenomenon easily occurring being repeatedly pierced, when elbow after piercing through is changed, there is the problem that cost is high, workload is large and risk is high.In addition, gas drilling scene application 90 degree and be provided with mounting flange, buffering cavity and the elbow that can thicken baffle plate, its cushion chamber physical efficiency effectively reduces band landwaste air-flow that pit shaft returns out to the erosion of elbow, when air-flow enters in buffering cavity, flow-disturbing is formed in buffering cavity, effectively reduce the erosion of air-flow to baffle plate, because the flange on elbow is mounting flange, when mounting flange is connected with the flange on liquid-operated flat valve, there is mounting flange and flange (flange on liquid-operated flat valve) and the problem that large and both angle adjustment of connecting bolt difficulty can not put in place is installed to hole.
Summary of the invention
the utility model provides a kind of erosion resistance elbow for gas drilling, overcomes the deficiency of above-mentioned prior art, its can effectively solve existing elbow with the Flange joint process on liquid-operated flat valve in exist the large problem of connecting bolt difficulty is installed to hole.
the technical solution of the utility model is realized by following measures: a kind of erosion resistance elbow for gas drilling, comprise elbow body and baffle plate, left link is had at the left part of elbow body, outside left link, loose flange is installed, right link is had at the right part of elbow body, cushion chamber is formed in right link inside, right flange is fixed with at right link, right flange and baffle plate are fixedly installed togather, there is lower link in the bottom of elbow body, be fixed with lower flange at lower link.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
can be installed with erosion resistance plate on the left of above-mentioned baffle plate, erosion resistance plate is positioned at cushion chamber.
above-mentioned erosion resistance plate can be quartz sand erosion resistance plate.
above-mentioned baffle plate can have installing hole, right flange has the mating holes corresponding with installing hole, right flange and baffle plate are fixedly installed togather by installing hole, mating holes and bolt.
above-mentioned baffle plate can be quartz sand baffle plate.
the utility model reasonable and compact in structure, easy to use, the setting of baffle plate can reduce the erosion of air-flow to elbow body, and the hole that the setting of loose flange is convenient on itself and liquid-operated flat valve is carried out hole, reduce the difficulty of hole being installed to connecting bolt, improve operating efficiency.When baffle plate is pierced, can being worked normally by the baffle plate more renewed, without the need to dismantling elbow, effectively reducing labour intensity and risk.
Accompanying drawing explanation
accompanying drawing 1 is the main TV structure schematic diagram of the utility model most preferred embodiment.
coding in accompanying drawing is respectively: 1 is elbow body, and 2 is baffle plate, and 3 is left link, and 4 is loose flange, and 5 is right link, and 6 is cushion chamber, and 7 is right flange, and 8 is lower link, and 9 is lower flange, and 10 is erosion resistance plate.
Detailed description of the invention
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. determines according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this erosion resistance elbow for gas drilling comprises elbow body 1 and baffle plate 2, left link 3 is had at the left part of elbow body 1, outside left link 3, loose flange 4 is installed, has right link 5 at the right part of elbow body 1, form cushion chamber 6 in right link 5 inside, right flange 7 is fixed with at right link 5, right flange 7 is fixedly installed togather with baffle plate 2, has lower link 8, be fixed with lower flange 9 at lower link 8 in the bottom of elbow body 1.Loose flange 4 is connected with the liquid-operated flat valve on well mouth rotary head side, in connection procedure, by adjustment loose flange 4, be convenient to the hole on loose flange 4 and the hole on liquid-operated flat valve carry out hole, make together with loose flange 4 is mounted by means of bolts on liquid-operated flat valve, lower flange 9 and sediment outflow pipeline are fixedly installed togather, air-flow in well enters elbow body 1 inside by left link 3 and is stopped by baffle plate 2, air-flow forms flow-disturbing in cushion chamber 6, reduce air-flow to the erosion of baffle plate 2, last air-flow enters sediment outflow pipeline.The setting of baffle plate 2 can reduce the erosion of air-flow to elbow body 1, and the hole that the setting of loose flange 4 is convenient on itself and liquid-operated flat valve is carried out hole, reduces the difficulty of hole being installed to connecting bolt, improves operating efficiency.When baffle plate 2 is pierced, can being worked normally by the baffle plate 2 more renewed, without the need to dismantling elbow, effectively reducing labour intensity and risk.
