Description
This control valve belongs to the control valve of adjusting or control technology, particularly liquid fuel furnace (kitchen range) usefulness of burning.
The present control valve of the liquid fuel furnace that uses generally all is to be transported to liquid fuel use amount in the stove with knob, gauge tap control with the band pressure-feed tank, also need lean on other method to go realization to warm-up operation.Whole combustion preheater, vaporization, combustion process can not be finished automatically in once-through operation, make troubles to the user.A kind of quantitative control preheated liquid fuel valve is also arranged, can only control pre-heating fuel usefulness, it and main control valve are disclosed, operation inconvenience, and control valve takies local big.Still there is a kind of liquid gas synchronous valve can not guarantee to be provided with liquid fuel in the gasification installation, increased preheating time.Also have a kind of control valve in addition, the gas after the gasification is through valve body, and valve body serviceability temperature height influences service life.
The research purpose of this control valve provides a kind of compact conformation, quantitative control preheated liquid fuel, automatic a kind of liquid fuel furnace control valve of lighting a fire that long preheating time in easy to use, life-span is short.
The technical scheme of this control valve is: its rotating shaft is installed in the valve body.Valve rod is in screw thread is spun on needle-valve body, and the valve rod other end is fastened in the rotating shaft.The passage m and the passage n that are connected are arranged in the needle-valve body.Two small valve cores are contained in respectively in the corresponding aperture of valve body, all at one end are set with sealing ring and protective sleeve, and the other end all is equipped with sealing ring and sleeve.Spring one end is pressed on the small valve core, and the other end is pressed in respectively on two joints.Two joints are tightened on the valve body respectively.Two small valve cores are with all gapped respectively between the valve body.There is passage g to be communicated with two corresponding apertures of valve body that small valve core is housed in the valve body.Two corresponding apertures of valve body of adorning two small valve cores have channel connection to elastic film one side.Be set with tapping cam and handle in the rotating shaft, on the tapping cam, be set with another handle.Clamp flexible film between gland and the valve body, between gland and the valve body cavity is arranged.Push rod one end is pressed on the elastic film, and the other end passes gland and stretches outside.Spring is installed on the push rod head, and other end roof pressure is at the gland inner face.The tapping cam is distributed with 2-4 raised section with on two contacted end faces of small valve core, and each raised section is made of one section inclined-plane and one section plane, and each planar section has the groove of location usefulness.
This control valve compact conformation, easy to operate, safe and reliable, can light a fire automatically, quantitatively discharging preheated fuel, the vaporization after gas without valve body, reduced heat loss, shorten vaporization time, controlled the temperature of valve simultaneously, improved the service life of valve.This control valve is applicable to that the various liquid fuel furnaces (kitchen range) of the liquefied synthetic fuel that uses alcohols, hydro carbons use.

Below in conjunction with accompanying drawing this control valve is described in further detail: valve body has several main thoroughfares on (24), liquid fuel enters through the joint (9) of feed liquor, enter the downside cavity of elastic film (25) through small valve core (14) and the formed gap a of valve body (24) and passage b, joint (7) through passage d and small valve core (13) and formed clearance C of valve body (24) and fluid enters preheating device again, also can discharge simultaneously through passage g and passage f, and enter gasification installation, carburretion is discharged through passage n and is entered burner after passage m enters.
Small valve core (13), (14) one ends are set with sealing ring (12) and protective sleeve (11), and the other end is equipped with sealing ring (15) and sleeve (16).Two small valve cores (13), (14) all are contained in the valve body (24).Spring (10) one ends are pressed on small valve core (13), (14), and the other end is pressed in respectively on joint (7), (9), and joint (7), (9) are tightened on respectively on the valve body (24).Rotating shaft (20) is installed in the valve body (24).Valve rod (2) is spun on needle-valve body (1) inner valve stem (2) other end through screw thread and is fastened in the rotating shaft (20) by screw (8).Sealing ring (4) is sleeved between needle-valve body (1) and the valve rod (2).Pad (3) pad is between sealing ring (4) and needle-valve body (1).Compacting ring (6) is pressed between sealing ring (4) and the pressure cap (5), and pressure cap (5) is spun on the needle-valve body (1).Pressing plate (17) is screwed on valve body (24).Support (18) is screwed on pressing plate (17).Also be set with tapping cam (19) and handle (23) in the rotating shaft (20), be set with handle (21) on the tapping cam (19).Gland (26) and elastic film (25) are fastened on the valve body (24) with screw, and push rod (27) one ends are through in the gland (26), and the other end is pressed on the elastic film (25) by spring (28).Discharge switch (29) is fixed on the gland (26), and withstands on the push rod (27).
There are three on the end face of tapping cam (19) by 120 ° of equally distributed raised sections, this raised section is made up of one section inclined-plane and one section plane, each planar section has the length range of groove (30) raised section of locating usefulness in 51 ° of angles, wherein the planar section length range is in 15 ° of angles, when rotating tapping cam (19) along center line, small valve core (13), (14) just can move up and down by these three raised sections, reach the purpose that opens and closes the passage that small valve core controls.The effect of groove (30) of location usefulness is the rotate operating position of control tapping cam (19) in the process of tapping cam (19).
This control valve comprises discharging preheated fuel, gas control and three parts of pre-heating fuel igniting.During the work of this valve, the discharging preheated fuel of elder generation.Inhour is rotated the handle (21) of tapping to ignition location, and tapping cam (19) is when some ignition locations, and the small valve core of discharge opeing (13) is in open mode at the peak of tapping cam (19).The small valve core of feed liquor (14) is in closed condition at the lowest part of tapping cam (19).With an ignition location in the process of another ignition location because the rotation of tapping cam (19), the inevitable minimum point that get back to tapping cam (19) under spring (10) effect of the small valve core of discharge opeing (13) is closed apocenosis passage.When being rotated further tapping cam (19), the small valve core of feed liquor (14) is pushed down under the effect on tapping cam (19) inclined-plane, feed pathway is opened, preheated liquid is through joint (9), passage b enters the bottom of elastic film (25), under the fluid pressure effect, push rod (27) is ejected, electrical pulse switch (29) is connected simultaneously, the igniting needle-discharging, the small valve core (13) of discharge opeing this moment is in the minimum point of tapping cam (19), get back to the lowest part of tapping cam (19) up to the small valve core (14) of feed liquor, close feed pathway, the small valve core of discharge opeing (13) under the effect on tapping cam (19) inclined-plane, arrives the peak of tapping cam (19) again again gradually, the small valve core of discharge opeing (13) is depressed, and the liquid of its underpart is through passage d, the joint of discharge opeing (7) is discharged gradually to be entered in the preheating cavity.After the liquid of elastic film (25) bottom had all been arranged, electrical pulse switch (29) cut off, thereby finished quantitatively discharging preheated fuel and igniting action.
After reaching preheating time, be rotated counterclockwise the handle (23) that is used for gas control, rotating shaft (20) drives valve rod (2) and rotates, thereby makes the fuel after the vaporization enter the burner internal combustion through the formed gap of needle point and the passage n of passage m, needle-valve body (1) and valve rod (2).
