According to the hoop, the pipelines can be connected rapidly and conveniently, and meanwhile no leakage can be ensured.
Description
Technical field
The utility model relates to the joint that pipeline connects fast, is specially a kind of FGD spraying tube and connects and use clip fast.
Background technique
At present, domestic flue gas desulfurization technique has the multiple sulfur removal technologies such as wet desulphurization, dry desulfurization, and wherein, Limestone-gypsum Wet Flue Gas Desulfurization Process technique (being called for short FGD) technology maturation, be most widely used, and social benefit is remarkable.
Both at home and abroad thermal power plant FGD spraying tube arm and arm and arm with usually all adopt bonding or flange connection being connected of nozzle.In use as pipeline when cracking occur, the cracking unit subtube can only be clipped again bondingly, the pipeline strength after bonding, lower than former integrated piping, makes spraying tube entire system strength decreased.Nozzle in use is prone to blocking phenomenon, will have a strong impact on the FGD desulphurization efficiency, while changing nozzle, as adopts the form of bonding connection, needs the section of tubing of joint is clipped in the lump; As adopt the flange Connecting format, need it is pulled down to replacing.Above several Placements have not only increased the maintenance workload of system, and when adopting flange to connect because of requirement for anticorrosion is arranged, need a large amount of expensive alloy material making of adopting, increased system cost.For realizing that the FGD spray system is conveniently safeguarded, reduce maintenance workload and maintenance cost, in the urgent need to developing a kind of clip that can realize quick connection.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of FGD spraying tube simple in structure, ingenious, rational to connect fast and uses clip, and this clip connected pipeline is quick and convenient, can guarantee simultaneously without leaking.
The technological scheme provided according to the utility model: a kind of FGD spraying tube connects fast uses clip, be characterised in that: comprise the first snap ring, the second snap ring, one end of described the first snap ring and an end of the second snap ring link together by bearing pin, the other end of the first snap ring is connected by clamping bolt with the other end of the second snap ring, inboard and the second snap ring inboard is provided with the groove of mutual perforation at the first snap ring, in described groove, tensioning has seal ring, seal ring has the first sealed department extended vertically, the 3rd sealed department and the second sealed department radially extended, and the second sealed department is placed in described the first sealed department, in the middle of the 3rd sealed department.
As further improvement of the utility model, described the second sealed department inner ring has the V-type groove.
Compared with prior art, advantage is the utility model: the utility model can effectively reduce the maintenance workload of FGD spraying tube system, improves entire system intensity, reduces the system fabricating cost; Find in actual applications, the utility model FGD spraying tube connects fast uses clip, has obtained and has reduced workload and fall for power plant the good result that this section is propped up, and has reached the purpose of research and development fully.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, the first snap ring 1, clamping bolt 2, seal ring 3, bearing pin 4, groove 5, the second snap ring 6, the first pipeline 7, second pipe 8 etc.
As shown in Figure 1, a kind of FGD spraying tube connects fast uses clip, comprise the first snap ring 1, the second snap ring 6, one end of one end of described the first snap ring 1 and the second snap ring 6 links together by bearing pin 4, the other end of the other end of the first snap ring 1 and the second snap ring 6 is connected by clamping bolt 2, inboard and the second snap ring 6 inboards are provided with the groove 5 of mutual perforation at the first snap ring 1, in described groove 5, tensioning has seal ring 3, seal ring 3 has the first sealed department 3-1 extended vertically, the 3rd sealed department 3-3 and the second sealed department 3-2 radially extended, and the second sealed department 3-2 is placed in described the first sealed department 3-1, in the middle of the 3rd sealed department 3-3.
Described the second sealed department 3-2 inner ring has the V-type groove.
The utility model working procedure and principle are as follows: at first seal ring 3 is arranged on and needs between the first pipeline 7 and second pipe 8 that connect, the first sealed department 3-1 of seal ring 3 and the 3rd sealed department 3-3 fit tightly respectively on the outer peripheral surface of the first pipeline 7 and second pipe 8, the pipe end of the pipe end of the first pipeline 7 and second pipe 8 is clamped in the second sealed department 3-2 between the two, for guaranteeing that pipeline connects rear good sealing effect, the second sealed department 3-2 inner ring preferably extends to the inner-walls of duct place; Then the first snap ring 1 of split type clip and the second snap ring 6 are locked on to seal ring 3 outsides, make seal ring 3 be placed in the groove 5 of the first snap ring 1 and the second snap ring 6, then the first snap ring 1 and the second snap ring 6 two ends are fastened by bearing pin 4 and clamping bolt 2 respectively, the first pipeline 7 and second pipe 8 can be tightly connected.
The utility model adopts split type structure, can meet the quick mounting requirement, and the seal ring 3 of pipeline junction adopts lip formula three surface seal structures simultaneously, takes full advantage of the elasticity of rubber and the pressure of the interior liquid of pipeline and seals, and guarantees to use without leaking.Shell ring adopts high strength fibre reinforced plastic (Fiber Reinforced Plastic, FRP) mold pressing is made, and guarantees the bulk strength of shell ring, and seal ring 3 adopts neoprene to make, utilize the elasticity of rubber and the pressure of the interior liquid of pipeline to seal, can guarantee without leaking; Further, in product development process, with Multi-axial composite felt and woven roving, replace the method for lamination, and in vinylite, add the ceramic carbon SiClx, FRP is improved, improve intensity and the antiwear property of FRP, guarantee the usability of clip; Clamping bolt 2 adopts anti-corrosive alloy material to make, to meet the clip whole service life.
The utility model can effectively reduce the maintenance workload of FGD spraying tube system, improves entire system intensity, reduces the system fabricating cost; Find in actual applications, the utility model FGD spraying tube connects fast uses clip, has obtained and has reduced workload and fall for power plant the good result that this section is propped up, and has reached the purpose of research and development fully.
