Description

The stepless adjustable valve of taper hole

(1) technical field:

The utility model relates to valve, the stepless adjustable valve of taper hole on particularly a kind of gas circuit or the liquid paths.

(2) background technique:

Valve on gas circuit or the liquid paths, with the gas ring lighting valve is example, the inlet hole of its valve body is a taper hole, the air outlet hole that communicates with taper hole is offered in the valve body side, the spool that cooperates with the valve body taper hole is a cone, two counterbores corresponding to the valve body air outlet hole are offered in the cone side, and two counterbore Edge Distances offer each pore of one of pore size respectively and communicate with the spool endoporus less than the air outlet hole diameter on the counterbore.During igniting, valve knob is opened maximum, drive valve core rotation make the counterbore of large aperture pore and valve body air outlet hole over against, the flame maximum of this moment, progressively turn round electronic striking knob (spool), the counterbore of the large aperture pore area that communicates with air outlet hole reduces gradually, flame is controlled to be reduced, when the counterbore of large aperture pore will turn over air outlet hole, the counterbore of another small aperture pore begins to connect with air outlet hole, along with constantly revolution of electronic striking knob (spool), the counterbore of large aperture pore turn over air outlet hole and the counterbore of small aperture pore and air outlet hole over against, continue revolution electronic striking knob (spool), the counterbore of the small aperture pore area that communicates with air outlet hole reduces gradually, and flame is controlled as minimum.

Can grow from said structure and to find out, the gas ring lighting valve has only two grades of flame intensities controls, though every grade of flame intensity control can realize step-less adjustment, can't accomplish omnidistance step-less adjustment control, brings inconvenience to the user.

(3) model utility content:

The utility model provides a kind of taper hole stepless adjustable valve, and its main purpose is to realize the omnidistance step-less adjustment flow of valve.

Can realize the stepless adjustable valve of taper hole of above-mentioned purpose, comprise spool and valve body, offer air inlet (liquid) hole on the valve body and (liquid) hole of giving vent to anger, different is that described air inlet (liquid) hole and (liquid) hole of giving vent to anger communicate by through hole, described spool is the awl bar, the awl bar be snug fit in the valve body with the concentric slideway of through hole in, bore shank diameter greater than through hole, the conehead of awl bar front end enters in the through hole, and the awl bar connects awl bar mobile mechanism outside valve body.

The awl bar is driven in the valve body slideway by awl bar mobile mechanism and moves forward to the end, awl bar conehead stops up through hole, air inlet (liquid) hole and give vent to anger and close between (liquid) hole, awl bar mobile mechanism drives the awl bar and moves after gradually in the valve body slideway, awl bar conehead leaves through hole conducting air inlet (liquid) hole gradually and gives vent to anger (liquid) hole, gap between conehead and the taper hole increases gradually, air inlet (liquid) hole increases gradually with ventilation (liquid) amount in (liquid) hole of giving vent to anger, otherwise then flow weakens gradually until closing, thereby realize omnidistance stepless control flow rate adjusting, advantage promptly of the present utility model place.

For preventing to bore the fitting surface clearance leakage gas of bar and slideway, be necessary to be provided with and to bore the seal ring that bar cooperates at the slideway inwall.

A kind of structure of described awl bar mobile mechanism is an eccentric rotary mechanism, comprise cam pin head and regulator plate, regulator plate is axially connecting the awl bar, the cam pin head is located on the electronic striking knob end face and is matched with in the square groove of regulator plate, described regulator plate is parallel with electronic striking knob end face, and described square groove is vertical with the awl bar.Described eccentric rotary mechanism is converted to awl bar moving back and forth in slideway by the rotation motion of cam pin head.

Described square groove length realizes moving back and forth of awl bar ultimate range greater than cam pin head swing diameter.

Guarantee good plugging effect, described through hole adopts the taper hole with the conehead coupling.

(4) description of drawings:

Fig. 1 is the structural representation of a kind of mode of execution of the utility model, shows the valve closing state.

Fig. 2 is in Fig. 1 mode of execution structural representation, shows valve opening state.

Figure number sign: 1, regulator plate; 2, valve body; 3, air inlet (liquid) hole; 4, (liquid) hole of giving vent to anger; 5, awl bar; 6, cam pin head; 7, electronic striking knob.

(5) embodiment:

The stepless adjustable valve of the utility model taper hole comprises spool and valve body 2.Described spool is the awl bar 5 that front end has conehead; Offer orthogonal air inlet (liquid) hole 3 and (liquid) hole 4 of giving vent to anger on the valve body 2, the taper hole of the conducting in air inlet (liquid) hole 3 and (liquid) hole 4 of giving vent to anger for offering to (liquid) hole 4 of giving vent to anger from air inlet (liquid) hole 3, offer and bore the slideway of bar 5 coupling along the axis of taper hole in valve body 2, slideway originates in gives vent to anger (liquid) hole 4 inwalls and ends on valve body 2 end faces; Awl bar 5 enters in the valve body 2 from the slideway mouth, and the conehead of awl bar 5 enters taper hole; The slideway inwall is provided with the seal ring of sealing awl bar 5 and slideway matching gap.

Awl bar 5 ends outside valve body 2 connect awl bar mobile mechanism, described awl bar mobile mechanism is an eccentric rotary mechanism, eccentric rotary mechanism is made of regulator plate 1 and cam pin head 6, regulator plate 1 is connected in awl bar 5 ends vertically, offer the square groove vertical with boring bar 5 on the regulator plate 1, cam pin head 6 is engaged in the square groove; Described cam pin head 6 off-centre are installed on the end face of electronic striking knob 7, and the end face of electronic striking knob 7 is parallel with regulator plate 1, and electronic striking knob 7 axis normal are in regulator plate 1.

The length of described square groove is greater than cam pin head 6 swing diameters.

As shown in Figure 1, when cam pin head 6 returned back to the outermost of square groove, the conehead of awl bar 5 stopped up through hole, and air inlet (liquid) hole 3 and gas (liquid) road of giving vent to anger between (liquid) hole 4 are closed.

Electronic striking knob 7 rotates, when the motion of square groove middle part, the conehead of awl bar 5 leaves through hole gradually gradually for 6 revolutions of cam pin head, cam pin head 6, slit between conehead and the through hole increases gradually, air inlet (liquid) hole 3 and gas (liquid) the road conducting between (liquid) hole 4 of giving vent to anger.As shown in Figure 2, when cam pin head 6 returns back to the middle part of square groove, the slit maximum between conehead and the through hole, air inlet (liquid) hole 3 and ventilation (liquid) amount of giving vent to anger between (liquid) hole 4 are maximum.
