Abstract
The utility model discloses a combined butterfly valve, which comprises a butterfly valve body (1), a connector (4) and a connector (6). The combined butterfly valve is characterized in that two sides of the butterfly valve body (1) are respectively provided with a flange (2), one side of each flange is fixedly connected with one connector, and screw holes of the other sides of the two flanges are fixedly connected with screw holes on the butterfly valve body via bolts (3). As the butterfly valve body and the two connectors are integrally connected via the bolts and the flanges, the butterfly valve can be mounted, dismounted and repaired fast and conveniently.
Description
Technical field
The utility model relates to a kind of shut-off means that has closure member, especially a kind of combined butterfly valve.
Background technique
As everyone knows, butterfly valve has that volume is little, simple in structure, and flow resistance is little, and it is little to open and close moment, flexible operation, can by, regulate flow and store up many advantages, and be widely used in controlling the middle or tube end of pipeline that fluid flows.But when in use installing or changeing normal structure length butterfly valve, because the size of pipeline length in reserve is difficult to guarantee, brings difficulty to installation, often needs to regulate connection with telescopic pipe, but telescopic pipe is often former thereby lose Telescopic because of corrosion, is difficult to pull down butterfly valve in maintenance.In reality is executed, be everlasting and place a cock wheel in the butterfly valve shaft, when the maintain and replace butterfly valve, have to adopt the plumbous mouth of gas welding method roastingization cock wheel, take off butterfly valve after removing cock wheel, increased butterfly valve replacing difficulty in order to substitute telescopic pipe.In addition, when movable (moving freely) tube end is installed butterfly valve, except that the need butterfly valve, also need joint,, both are closely cooperated so that link to each other with pipeline or storage interface, both are coupled together fast, present butterfly valve, the joint connector element need be purchased respectively, row combination again, be difficult to purchase supporting member simultaneously, make troubles to work, the interim connection expended the more time when using on the other hand, also cumbersome, influence working efficiency.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of installation, dismounting, combined butterfly valve easy to maintenance are provided.The purpose of this utility model realizes by following technical proposals: the utility model comprises butterfly type valve and joint, it is characterized in that the butterfly type valve both sides respectively establish a flange plate, flange plate one side and joint are affixed, and two flange plate opposite sides are integral through bolt is affixed by screw on screw on it and the butterfly valve.
Said joint is set as required, can be tool joint pin, also can be female joint.
Said tool joint pin is to be connected with ram's horn on the short tube exterior edge face.
Said female joint is that short tube outer end oral area is provided with one " O " RunddichtringO groove, is connected with seal ring is chimeric, is with a differential sliding sleeve on the short tube, and differential sliding sleeve is provided with the spiral projection outward.
During use, with combined butterfly valve two end connectors with need connecting tube or storage on corresponding connections of joint, i.e. tool joint pin links to each other with female joint, female joint be connected with tool joint pin and by ram's horn and spiral protruding rotate to fix get final product.
From above-mentioned situation as can be known, the purpose of this utility model can realize that butterfly valve and two joints link into an integrated entity by bolt and flange plate on the one hand, are convenient to the butterfly valve quick mounting, fast quick-detach and maintenance, and the utility model is particularly useful for oil well cementation ash can and connects.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises butterfly type valve 1 and joint 4,6, and a flange plate 2 is respectively established in the butterfly type valve both sides, and flange plate one side and joint are affixed, and said joint is set as required, can be tool joint pin 4, also can be female joint 6.Said tool joint pin is to be connected with ram's horn 5 on the short tube exterior edge face, the ram's horn number is decided as required, it generally is symmetric arrays, also can be and equidistantly distribute arrangement, present embodiment is selected two symmetric arrays for use, said female joint is that short tube outer end oral area is provided with one " O " RunddichtringO groove, so that peg graft with seal ring, is with a differential sliding sleeve 7 on the short tube.Differential sliding sleeve is provided with spiral projection 8, and the spiral projection can be a symmetric design, also equidistantly distributes arrangement design, and its number is decided according to tool joint pin ram's horn number, and present embodiment is selected two symmetric designs for use.Two flange plate opposite sides by screw on screw on it and the butterfly valve through bolt 3 affixed being integral.
