Background technique
The super flow control valve of adjustable suction magnet is mainly used in the keying control of the super stream of compressed petroleum gas gas, be installed in the valve of gas steel cylinder, its structure is that " control valve of improvement " of 200620113819.X is similar with disclosed China Patent No., mainly constitute by copper pressure head, air inlet joint, steel ball and magnetic stripe etc., be provided with first flow in the copper pressure head, be provided with second runner in the air inlet joint, between the first flow and second runner, be provided with the control mouth that connects.When magnetic stripe holds steel ball, compressed petroleum gas flows into second runner through first flow, control mouth, and when flow abnormity was excessive in the control valve, fluid strength overcame magnetic stripe suction and makes the steel ball sealing control mouth that comes off, thereby closed control valve prevents the danger of gas leak.Two kinds of structures that this patent mainly discloses control valve reach above-mentioned implementation result, and the magnetic stripe in first kind of structure is directly installed on copper pressure head the inner, can't adjust steel ball suction size during use, thus only can control a kind of keying of flow, comparatively single on the function; Second kind of structure is that passage is set on air inlet joint, adjustment piece and magnetic stripe are housed in the passage, adjust the height of magnetic stripe mounting point in passage by adjustment piece, thereby reach the purpose of control steel ball suction size, can satisfy various flow needs and surpass flow resistance cutout amount adjustment setting at any time though this structure is compared first kind of structure, but the adjustment of steel ball suction size comparatively bothers, and magnetic stripe is installed also comparatively inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and provides a kind of steel ball suction size to adjust simple, the magnetic stripe super flow control valve of adjustable suction magnet easy for installation.
Technical problem of the present utility model is achieved through the following technical solutions:
The super flow control valve of a kind of adjustable suction magnet, be installed in the valve of gas steel cylinder, comprise the copper pressure head and the air inlet joint that is connected valve export that connect non-return structure in the valve, described copper pressure head close-fitting is connected the air inlet end of air inlet joint, be provided with the first flow and second runner that connect in this copper pressure head and the air inlet joint, and between the first flow and second runner, be provided with the control mouth that connects, magnetic stripe is equipped with at this control mouth place, and be subjected to this magnetic stripe absorption to open the control mouth or the steel ball of the sealing control mouth that comes off, be provided with the steel ball chamber that connects the first flow and second runner respectively in the described copper pressure head, above-mentioned steel ball is located in this steel ball chamber; The inner side face of described copper pressure head is provided with annular groove, also is provided with the passage that connects annular groove and steel ball chamber respectively, and above-mentioned magnetic stripe is located on this passage.
Magnetic stripe central angle alpha in the described annular groove is 90 °～180 °.
Compared with prior art, the utility model mainly is to be provided with the steel ball chamber of installing for steel ball in the copper pressure head of control valve, the side face of copper pressure head is provided with annular groove, also be provided with the passage that connects annular groove and steel ball chamber respectively, and on this passage, be provided with magnetic stripe, area coverage by control magnetic stripe and passage to be reaching the purpose of adjusting magnetic stripe and steel ball suction size, and the structure after the improvement has that steel ball suction size is adjusted simply, magnetic stripe is easy for installation, can satisfy various flow needs and surpass the advantage of flow resistance cutout amount adjustment setting at any time.

Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1～shown in Figure 3,1. copper pressure head, 2. steel ball chamber, 3. annular groove, 4. steel ball, 5. air inlet joint, 6. second runner, 7. control mouth, 8. passage, 9. magnetic stripe, 10. first flow.
The super flow control valve of a kind of adjustable suction magnet, be installed in the valve of gas steel cylinder, be mainly used in the inlet end of control compressed petroleum gas reduction valve, it comprises the air inlet joint 5 at the copper pressure head 1 that connects non-return structure in the valve and the valve export place that is threaded, and copper pressure head 1 riveting close-fitting is connected the air inlet end of air inlet joint 5.
Be provided with the first flow 10 and the steel ball chamber 2 that connect in the described copper pressure head 1, first flow is positioned at copper pressure head outer end, and the steel ball chamber is positioned at copper pressure head the inner, and steel ball 4 is housed in steel ball chamber 2; Simultaneously, copper pressure head 1 inner side face is provided with annular groove 3, the magnetic stripe 9 that coincide with annular groove is housed in this annular groove, the central angle alpha of magnetic stripe is 90 °～180 °, also be provided with the passage 8 that connects annular groove and steel ball chamber 2 respectively, this channel width is less than magnetic stripe length, can form the suction structure mutually of magnetic stripe 9 and steel ball 4 through this passage.
Before installing, described magnetic stripe 9 need elder generation to determine the compressed petroleum gas flow size of passing through in the control valve, and then the suction power of magnetic stripe and steel ball 4 is set, specifically be to decide by the size of adjusting magnetic stripe 9 covering passages 8 width, magnetic stripe covers whole passage fully, and then suction is the strongest; The area coverage of magnetic stripe and passage is more little, and then suction is weak more.After the compressed petroleum gas flow that magnetic stripe 9 passes through in according to control valve has been determined the mounting point, can dash a little spacing at the magnetic stripe two ends.
Be provided with second runner 6 that communicates with first flow 10, the steel ball chamber 2 of copper pressure head 1 in the described air inlet joint 5, and be provided with control mouth 7 at the second runner place in adjacent steel ball chamber, the bore of this control mouth is less than steel ball 4 external diameters, so can be sealed by steel ball.
The super stream that this control valve is mainly used in compressed petroleum gas gas opens and closes control, satisfies various flow needs by adjusting 9 pairs of steel ball 4 suction sizes of magnetic stripe, and the adjustment that therefore can surpass flow resistance cutout amount is at any time set.Compressed petroleum gas shown in Fig. 1, Fig. 3 arrow, is to flow to air inlet joint 5 from copper pressure head 1 in the flow direction in the utility model.Under the normal working, magnetic stripe 9 absorption steel balls 4 are opened control mouth 7, and compressed petroleum gas flows in second runner 6 of air inlet joint 5 through control mouth 7 by first flow 10, the steel ball chamber 2 of copper pressure head; When flow abnormity was excessive in the control valve, fluid strength overcame magnetic stripe 9 suction and makes the steel ball 4 sealing control mouth 7 that comes off, thus closed control valve, to prevent the danger of gas leak.
