Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Improvement in the utility model is mainly the structure of flap, and has increased adjustment sheet and regulating sleeve, and wherein adjustment sheet and regulating sleeve are all regulating action, and adjustment sheet and/or regulating sleeve can be according to circumstances optionally installed.Concrete structure is described below:
High temperature resistant pneumatic stopping valve, comprise valve body 1, valve body 26, the interior placement sleeve 2 of valve body 26, one side of sleeve 2 lower ends connects valve body 1, and sleeve 2 inwalls offer the open-work 2-1 of different inner diameters from bottom to top, and open-work is arranged according to the circumferencial direction of sleeve, open-work diameter on every circle circumference is identical, the open-work diameter of axial direction is not identical, and open-work diameter is ascending arrangement from bottom to top, and the diameter of described open-work is 3-11.5mm.
Flap 3 is installed in sleeve, preferably flap is cylindrical-shaped structure, centre has step type blind hole, on flap end face, offer several through hole 3-1, in the middle of flap, be designed with register pin (not shown), streamline groove 3-2 is set on the side of flap, this design is in order to prevent that flap is when being heated high temperature, heat radiation is slow, yielding, fragile.
Valve rod 1 is set on flap, flap 3 is followed valve rod one and can be moved along sleeve lining, valve rod one is through the bottom of valve gap 7 and pedestal 9, the outside socket valve body 26 of sleeve, between valve body one and valve body two, be provided with adjustment sheet 16, valve body one is provided with activity adjustment screw 5 with sleeve joint, the upper end of valve body two connects valve gap 7, between valve gap 7 and valve body two, be provided with seal ring 17, valve gap 7 is by valve body two sealings, on valve gap 7, connection base frame 9, the upper end of pedestal connects valve head base 10, on valve head base, be provided with suction port and air outlet 11, the upper end of valve head base connects valve head 12, in valve head, there is piston 13, piston 13 moves along the inwall of valve head, valve rod two 4-1 are through piston, valve head base, behind pedestal top, be connected with valve rod one, valve rod one is crossed flexible connection button 18 with valve rod two-way and is connected, at the top of valve rod one, connect high-temperature spiral gland 19 simultaneously, valve rod one is prevented valve rod one and is flexibly connected button disengaging by high-temperature spiral gland in movable process.The upper end connection valve skull 14 of valve head, arranges elastic element between valve head lid and valve rod two, the preferred spring 15 of elastic element, and the top of valve rod two is socketed on spring 15.The heat insulation graphite pads 20 of metal hemming edge is set between pedestal and valve head base, positioning work piece 22 and suction port, air outlet are set on valve head lid 14.Piston and valve head inwall contacting point arrange high-temperature resistant seal ring 21 on piston.Steel toothed washer (not shown) is equipped with valve body one, valve body two joints in sleeve bottom, steel dentiform gasket encloses high temperature resistant and seal action, why use steel toothed washer, with valve body one, valve body upper and lower end face, to connect more identical because its tooth Shape Design makes sleeve bottom, sealing is strong, not yielding and damage under high temperature action.Whole part in the utility model accompanying drawing 1 on the heat insulation graphite pads 20 of metal hemming edge should be referred to as valve head in the industry, also makes pneumatic actuator also be cylinder, is commonly called as pneumatic head, has been carried out for convenience of description parts and has disassembled.
The through hole 3-1 offering on flap is the aperture for flow, and side has streamline groove 3-2, and this design is in order to prevent that flap is when being heated high temperature, heat radiation is slow, yielding, fragile designed, when flap moves from bottom to top, the height that rises and arrive according to flap, the open-work that has different inner diameters increases flow, and more upwards flow is larger, contrary, more downward, flow is less. and flap moves up and down and is controlled by positioning work piece 22.After flap is connected with valve rod one, for fear of flap and valve rod one, depart from, in the bottom of flap, connect a nut.
The through hole 3-1 offering on flap can regulate according to valve aperture size, and valve aperture is larger, and required open-work quantity can increase, and it is large that open-work internal diameter also can become.
In prior art, water flows in sleeve from valve body one, the application is the valve for hot environment, after valve temperature height, water can produce gas and enter in the gap between flap and sleeve, although the gap between flap and sleeve is especially little, water also can enter in sleeve by gap once in a while, in order to prevent in use that the G&W of high temperature cannot be discharged in time and in the hot environment lower Disc situation such as stuck of easily swelling, so have many apertures and have at flap the streamline groove that supplies water and reflux around on flap, make to enter the water in sleeve, the open-work of gas from flap refluxes again, and flap can rise or decline according to the water level that enters valve body one, water also can flow out from open-work, in order to control the water yield flowing out from open-work, by positioning work piece, make the height of flap can regulate location, because the diameter of different heights open-work is inconsistent, therefore when the height difference of flap, the water flowing out from open-work can quantitatively flow out.
The utility model is simple in structure, easy to use, practical, can be energy-efficient, flap, sleeve, the design of adjustment sheet efficiently solves high temperature pneumatic stopping valve, and in use noise is large, and flap heat radiation is slow, yielding, regulate inconvenient, the drawback such as pneumatic element is fragile.
In the utility model, changed the structure of pedestal and flap, and pretended adjustment sheet between valve body one and valve body two, in the utility model, the change of structure can make noise of the present utility model little, rapid heat dissipation, reduce the loss of valve pneumatic component in use in hot environment, Yancheng the working life of valve, elegant in appearance, and valve in use section passes through the arbitrary adjusting of adjustment sheet according to needed uninterrupted, valve flap structure in the utility model, make flow more controlled, rapid heat dissipation, can temperature distortion.
These are only the utility model embodiment's preferred embodiment; not in order to limit the utility model embodiment; all within the utility model embodiment's spirit and principle; any modification of doing, be equal to replacement, improvement etc., all should be included in the utility model embodiment's protection domain.
