Description
Technical field
The utility model relates to the valve body of the flow of a kind of adjustments of gas or liquid, relates in particular to a kind of oil gas with the oblique flap valve of the step type on the burner.
Background technique
Flow and the pressure that use needle-valve to carry out control gaseous or liquid on the conveyance conduit of present various vaporized light oil stove, petroleum gas or liquid oil plant etc. more.By adjusting the gap of spool and valve base cavity body, thereby reach the gas that adjustment will carry or the flow and the pressure of liquid.For example the someone has applied for patent: " a kind of needle-valve of precision (CN2505652) ", it is made up of valve body and needle two-part, air valve body inner chamber front aperture is conical, the front end of needle is a cone, needle once is equiped with O type rubber seal backward, regulates outside thread, is equipped with cap, handwheel, and needle inserts body cavity and matches, liquid gas drives the rotation of needle adjusting outside thread by the rotation of handwheel, reaches the size and the switching gas effect of control flow of lpg.The front end of valve body is a cone, though can adjust the throughput of liquid gas, accurate inadequately, needle passes in and out in valve body fast, can not the better controlled air demand.
Summary of the invention
The utility model has mainly provided a kind of simple and reasonable, adjustment air feed or the pressure of fuel feeding and the oblique flap valve of step type of flow that can be in proper order; Solve adjustment throughput or fluid flow that existing in prior technology can not be in proper order, the problem that wastes energy.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the oblique flap valve of step type comprises valve body, the spool that is slidingly matched with body cavity; Valve body is provided with inlet pipeline and outlet conduit, one end of spool is connected with valve rod, and external peripheral surface is the inclined-plane or the conical surface on the spool, is connected with control section at the other end of spool, described control section is the multidiameter shaft shape, and the maximum diameter of multidiameter shaft is less than or equal to the diameter of inlet pipeline.Described inclined-plane can be that the capable inclined-plane of the tongue of stroke also can be that cylindrical body is lathed a round platform or coniform, makes the outer surface of spool become the conical surface with cylindrical body or plane of cone cutting.The inclined-plane or the conical surface can both make when spool by valve rod during to inner rotary, the gap of spool and valve body is gradual change, has so just well regulated the proportioning of oil gas.In order further to control the gas oil ratio ratio, thereby make the burning intensity of a fire can be divided into different grades, step is set, limited the oil mass that import enters at the free end of spool according to user's demand, thereby can better control the proportioning of oil gas, reach different intensity of a fire requirements.When not using, ladder shaft part integral body is in the inlet pipeline, utilizes the inclined-plane airtight; During use,, thereby be divided into several stage control oil-gas ratins with the sectional back-out of ladder section.
The shape of spool can be the halfpace shape, also can be round table-like, and the ladder number of spool end can be divided according to user's selection, and as preferably, described spool is round table-like, and inlet pipeline and spool connecting part are arc section; The ladder shaft part of spool end is divided into three sections, and the bottom surface of multidiameter shaft is the cambered surface that cooperates with inlet pipeline.In the inlet pipeline cooperation place of spool and body cavity, the body cavity wall is made circular-arc, not only combination process requirement, and can be so that spool and valve seal are better.The ladder shaft part is divided into three sections, controls big fire, moderate heat and little fire respectively.When spool and valve seal, ladder section integral body is in the inlet pipeline, and during use, match with inlet pipeline all the time in the bottom surface of ladder shaft part, and oil inlet quantity is by the shoulder height control of ladder section, and is more accurate.In little when fire, screw out sub-fraction with spool, and the first ladder section of ladder shaft part screws out pipeline, spills certain clearance; When needs are transferred the intensity of a fire when big, rotary spool makes the second ladder section screw out pipeline again, and the gap increases and cooperating corresponding air inflow; When the intensity of a fire of needs maximum, the ladder section is all screwed out inlet pipeline.
As preferably, the bottom one layer surface of described ladder shaft part is oblique ligule.The incremental adjusting oil and gas content of oblique ligule energy.
As preferably, described spool is in axial direction gone up the valve rod that connects and is provided with one section screw thread, and the valve rod behind the thread section is provided with seal ring; Be socketed with the tightening nut that is connected with valve body on the valve rod.Worm structure is made simple, and is easy to operate, seal ring is set thereon prevents leakage of oil or gas, exposes when making the unlikely because rotary spool of liquid.Nut can be locked valve rod, closely is connected with valve body.
Screw thread can be a multiple thread, also can be single screw thread, and number of starts can be regulated according to the length of ladder section.As preferably, described screw thread is a multiple thread.Multiple thread can screw out spool fast, makes things convenient for oil gas to mix.As more preferably, number of starts is 3.
As preferably, be provided with fork or be socketed with gear in the free end side of valve rod.By the openings of sizes synchronization control of the inlet hole on fork or gear and the burner, thereby make firing effect better.
As preferably, valve body suction port one end dorsad is provided with screw thread, which is provided with nut.
Therefore, the oblique flap valve of step type of the present utility model has simple and reasonable, use easy to operate, adjusting throughput or fluid flow that can be in proper order, the advantage of energy saving.
When the oblique flap valve of step type of the present utility model has improved original conical needle valve regulation flow, just reach the peak quickly, change comparatively fast relatively, regulate insensitive shortcoming, can make flow, become the curvilinear motion of approximate direct ratio along with the moving of spool.
