Description
Technical field
The present invention relates to modulating valve technical field, especially relate to a kind of ball float pry type modulating valve.
Background technique
Water heating type radiator is the major way of current north of china in winter heating.In the process of heating, once have air in radiator, the hot water in radiator cannot circulate, thus radiator venting in good time.For this reason, radiator must be provided with relief opening, and this relief opening is provided with lid, in the time of needs exhaust, only needs lid to take down.But in exhaust process, user must keep at the scene and spray with the drained rear water of gas-tight, thereby convenient not.Although, there are some modulating valve that can help radiator to exit voluntarily, most structures are comparatively complicated, or volume is larger, and versatility is not strong.
Summary of the invention
The object of this invention is to provide a kind of ball float pry type modulating valve, it has simple in structure, small volume, feature that versatility is stronger.
The technical solution adopted in the present invention is: ball float pry type modulating valve, comprise valve body, this valve body has inner chamber, the left side of this inner chamber is provided with gas-entered passageway and switch passage, this inner chamber bottom is provided with the tapered opening upwards of large end, in this tapered opening, be provided with large end at conical head upper and that prepare for rubber material, between the upper end of this conical head and the top of this valve body, be provided with extension spring, and, in this switch passage, be provided with ripping bar, the middle part of this ripping bar is hinged in the middle part of this switch passage, and the right-hand member of this ripping bar is connected with the upper end of this conical head, the left side of described valve body is provided with switch body, this switch body has ball float chamber, and the left part in this ball float chamber is provided with suction port, this suction port has internal thread, simultaneously, in this ball float chamber, be provided with ball float, this ball float middle part is provided with perforation, the left part of this ripping bar is through in this perforation, and, the left end of this gas-entered passageway is communicated to this ball float chamber.
The left part in described ball float chamber is bolted with lid, and this suction port is positioned on this lid.
The top of described tapered opening is provided with guard.
The advantage that the present invention has is: simple in structure, and small volume, versatility is stronger.Ball float pry type modulating valve of the present invention utilizes ball float to drive ripping bar, realizes the sealing of conical head to tapered opening and opens, thereby realizing the self-exhausting of radiator.Because all parts of this modulating valve are comparatively concentrated, thereby small volume can directly be connected on the air outlet of radiator by the mode being spirally connected, thereby versatility is stronger.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks sectional view.
In figure: 10, valve body, 11, inner chamber, 12, gas-entered passageway, 13, switch passage, 14, tapered opening; 20, conical head; 30, extension spring; 40, ripping bar; 50, switch body, 51, ball float chamber; 60, ball float, 61, perforation; 70, lid; 80, guard.
Embodiment
Embodiment, as shown in Figure 1: ball float pry type modulating valve, comprises the valve body 10 linking together and be positioned at the switch body 50 in these valve body 10 left sides.Wherein:
This valve body 10 has inner chamber 11.The left side of this inner chamber 11 is provided with gas-entered passageway 12 and switch passage 13.These inner chamber 11 bottoms are provided with the tapered opening 14 upwards of large end.In this tapered opening 14, be provided with large end at conical head 20 upper and that prepare for rubber material, between the upper end of this conical head 20 and the top of this valve body 10, be provided with extension spring 30.And, in this switch passage 13, being provided with ripping bar 40, the middle part of this ripping bar 40 is hinged in the middle part of this switch passage 13, and the right-hand member of this ripping bar 40 is connected with the upper end of this conical head 20.
This switch body 50 has ball float chamber 51, and the left part in this ball float chamber 51 is provided with suction port 52, and this suction port 52 has the internal thread that can carry out with the air outlet of radiator threaded.Meanwhile, in this ball float chamber 51, be provided with ball float 60, these ball float 60 middle parts are provided with perforation 61, and the left part of this ripping bar 40 is through in this perforation 61.And the left end of this gas-entered passageway 12 is communicated to this ball float chamber 51.
Further say, the left part in this ball float chamber 51 is bolted with lid 70, and this suction port 52 is positioned on this lid 70.Like this, be convenient to the assembling of this ball float 60.
Continue to optimize, the top of this tapered opening 14 is provided with to protect the top of this conical head 20 and the guard 80 of this tapered opening 14.
Course of action of the present invention: have air in radiator time, this ball float is in bottom, and the right-hand member of this ripping bar lifts under the effect of this extension spring, and this conical head can not stop up this tapered opening, and then air in radiator can automatically be discharged in this tapered opening.Once the air in this radiator drains only, the water in radiator enters in this ball float chamber, and this ball float is lifted, thereby the left end of this ripping bar lifts, right-hand member moves down, and stops up closely this tapered opening after then making this conical head move down, and has avoided the ejection of water.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
