Abstract
The utility model discloses a steam thermal insulation blowing gas butterfly valve and belongs to the field of pipeline valves. The steam thermal insulation blowing gas butterfly valve comprises a main valve body (2) and a transmission device (1) which are fixedly connected, wherein a blowing device, a fixing ring (6), a butterfly plate (7) and a valve rod (5) are arranged in the main valve body (2); and the steam thermal insulation blowing gas butterfly valve is characterized in that the main valve body (2) is provided with an integral jacket (6); the jacket is provided with an outlet (4) and an inlet (3); and the mounting positions of the outlet (4) and the inlet (3) are symmetrical to a central line of the pipeline of the main valve body (2). By the integral jacket, steam/hot water and other thermal media are circularly heated in the jacket of the main valve body through the inlet and the outlet; when the thermal media enter the jacket from the inlet and are discharged out of the outlet, the thermal media come around the total periphery of the pipeline of the main valve body; the steam flow and heat exchange area are increased; the thermal insulation effect is improved; and coal tar attached to the metal sealing surface can be well removed under the action of a blowing device, so that the valve is flexibly opened and closed and reliably sealed.
Description
Technical field
The utility model provides a kind of steam insulation injection coal gas butterfly valve, belongs to the pipeline valve field.
Background technique
Existing steam blast metal hard-sealing butterfly valve, when outside air temperature reduced, impurity and coal tar oil solidified easily in the gas pipe line, and the winding-up that makes is not thorough, and difficult spray is swept clean, influences the gas valve sealing.
Chinese patent CN200920097707.3 discloses the special-purpose butterfly valve of a kind of blowing type coal gas.The special-purpose butterfly valve of this coal gas comprises the sealing surface that is formed by valve body and valve plate sealing; On the inwall of valve body, be fixed with annular steam pipe; On the tube wall of the annular steam pipe of sealing surface, be provided with several winding-ups mouthful; Annular steam pipe port closed wherein, another port lead on the outer wall of valve body and are connected with pipe valve.Realized high-temperature steam is evenly jetted to the sealing surface of easy blocking, the function that is set in the coal tar oil on the sealing surface is dissolved in dilution, and the deficiency of existence is that annular steam pipe is made difficulty; Cost is high, after steam gets into, big pressure need be provided; Have only steam that insulation is provided in addition, heat is not enough.
The model utility content
According to above deficiency of the prior art, the problem that the utility model will solve is: provide existing injection coal gas butterfly valve sealing surface impurity of a kind of solution or coal tar oil to solidify the poorly sealed close problem in back, the steam insulation injection coal gas butterfly valve of high insulating effect.
The utility model solves the technological scheme that its technical problem adopted: steam insulation injection coal gas butterfly valve; The main valve body and the transmission device that comprise fixed connection; Blowing device, retaining ring, butterfly plate and valve rod are set in the main valve body; It is characterized in that: main valve body is provided with the integral type chuck, and chuck is provided with import and outlet, and the mounting point of import and outlet is about main valve body pipeline center line symmetry.
On original steam winding-up metal hard-sealing butterfly valve basis; The integral type chuck is set; Make the heating that in the main valve body chuck, circulates of thermal mediums such as steam/heat water through import and export; Solidifying did not appear in interior impurity of gas pipe line or coal tar oil when particularly winter, outside air temperature reduced, and made valve opening and closing flexible, sealed tight.
Wherein preferred version is:
Described outlet is arranged on the main valve body bottom, and import is arranged on upper part of the main valve body.Line between import and the outlet can with valve rod at an angle, be provided with as required.
Described import is provided with the screw thread internal thread, and outlet is provided with the screw thread internal thread.The convenient connection, further reduce volume.
The beneficial effect that the steam insulation injection coal gas butterfly valve of the utility model is had is: through on original steam winding-up metal hard-sealing butterfly valve basis, the integral type chuck is set, makes the heating that in the main valve body chuck, circulates of thermal medium such as steam/heat water through import and export; Thermal medium gets into chuck from import, during from the outlet discharge, has walked around whole peripheries of main valve body pipeline; Steam flow and heat exchange area have been increased; Improve heat insulation effect, make valve opening and closing more flexible, seal more reliable; Can not only keep the interior medium temperature of valve to make it softening automatically, and under the blowing device effect, can better remove the coal tar oil that adheres on the metallic sealing section.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Embodiment 1:
As scheme shown in the l; Main valve body 2 is fixedly connected with transmission device 1, and blowing device, retaining ring, butterfly plate and valve rod are set in the main valve body 2, and main valve body 2 is provided with integral type chuck 6; Chuck 6 is provided with outlet 4 and import 3, and the mounting point of outlet 4 and import 3 is about main valve body 2 pipeline center lines symmetry.
On original steam winding-up metal hard-sealing butterfly valve basis, integral type chuck 6 is set, make the heating that in main valve body chuck 6, circulates of thermal medium such as steam/heat water through import and export.Be fixed with the suction valve 5 of steam blast device on the side of main valve body 2, the fixed installation blowing device arranged in main valve body 2 inboards over against air valve.The retaining ring below is equipped with seal ring, and annular pressing plate is fixed on seal ring on the butterfly plate through set screw, and butterfly plate is installed in the main valve body 2 through valve rod, and closely cooperates with the butterfly plate seal ring, under the worm and gear transmission, opens and closes flexibly.Outlet 4 and the import 3 arbitrarily angled setting that can tilt at the chuck 6 of main valve body 2.
Embodiment 2:
On embodiment 1 basis, outlet 4 is arranged on main valve body 2 bottoms, and import 3 is arranged on main valve body 2 tops.Import 3 and export between 4 line can with valve rod at an angle, be provided with as required.
Embodiment 3:
On above embodiment's basis, import 3 is provided with the screw thread internal thread, and outlet 4 is provided with the screw thread internal thread, increases the simplicity that connects steam pipework.
