Description
One, technical field
The present invention relates to a kind of test splice, especially a kind of energy replaces manual bleed valve, is applicable to domestic air conditioning, heating installation or various heating equipment, is specially adapted to hot-water heating, is used to test the also test splice of exhaust.
Two, background technique
Along with improving constantly of the warming of global weather, people's living standard, air-conditioning, heating installation have entered huge numbers of families, and at present, the manual bleed valve of generally installing on air-conditioning, the heating installation often because forget venting, and can not make air-conditioning, heating installation normally bring into play effect; And artificial venting often there are flowing out, and easily pollutes wall, ground or furniture; Also have, because not discharging in time of air, water flows " to gurgle " at pipeline always and makes a sound, and in early morning, usually stirs us awake from fond dream.Because air makes progress away the influenced maximum of the family that lives on the top floor.
Three, summary of the invention
The objective of the invention is to solve above-mentioned existing air-conditioning venting undesirable, often deficiency such as there are flowing out, a kind of test vent connection that is used for heating equipment is provided, can replace manual bleed valve, be applicable to domestic air conditioning, heating installation or various heating equipment, can test and the interior air of timely blowdown piping, and can prevent that water overflows in the pipeline, make its have venting convenient, do not have the phenomenon of metalling run out, rational in infrastructure, safe and reliable, make characteristics such as simple, easy to use.
The objective of the invention is to adopt following scheme to realize: a kind of test vent connection that is used for heating equipment, it comprises the nut that has internal thread and has externally threaded adapter body, be characterized in: it also comprises the test exhaust component, described nut and adapter body constitute valve body, through hole is arranged in the adapter body, the through hole internal diameter is littler than the internal diameter of nut, and is connected with the conical surface between the through hole of adapter body and the internal thread through hole; The outside thread and the airexamination apparatus of valve body one end are connected to become relief opening, and the internal thread of the other end and refrigerant water pipe or circulating pipe are connected to become suction port; Described test exhaust component comprise dress insert spool in the valve body, be enclosed within the spool middle part seal ring, be contained in the nut to cross to coil and cooperate and be fixed on the back-up ring in the valve body and be enclosed within spool lower end one end and withstand the spring that spool, an end withstand back-up ring with internal thread.
Above-mentioned spool inserts in the through hole of adapter body of valve body, can move up and down in valve body, contact by seal ring between spool and the valve body, utilizes elastic force to make seal ring contact closing seam with the valve body inner conical surface, is used for preventing that the interior water of pipeline from overflowing; Below spool lower end, seal ring, become U-shaped crotch cover upper spring; It is exhaust port that spool middle part, seal ring top are provided with through hole, and the axial direction on spool top has a upright opening to be communicated with exhaust port.
The present invention adopts the beneficial effect of such scheme to be: 1) open or close passage between joint suction port and the relief opening by moving up and down of spool, whole test splice is simple in structure, and venting is convenient, low price; 2) test splice all is made up of mechanical part, and joint stimulates the menstrual flow big or small unfettered, safe and reliable; 3) spool of dress seal ring is to adopt spring to support, and utilizes elastic force to make the closure that contacts of seal ring and valve body inner conical surface, guarantees the sealing under the situation of not exhaust, guarantees the nothing phenomenon of metalling run out; 4) adopt movable connection of spring that spool is moved freely,, cause system can not work and leak so can when long-time running, not produce corrosion; 5) back-up ring is contained in the nut, can be used for withstanding spring spool can be moved up and down, and can also dwindle the space and stop that water overflows in the pipeline.

Five, embodiment
Below in conjunction with accompanying drawing the embodiment that the present invention is used for the test vent connection of heating equipment is described in detail.
As shown in Figure 1, 2, the schematic perspective view that is used for the test vent connection of heating equipment for the present invention, a kind of test vent connection that is used for heating equipment, it comprises the nut that has internal thread 7 and has the adapter body of outside thread 6, it also comprises the test exhaust component, and described nut and adapter body constitute valve body 2, and through hole is arranged in the adapter body, the through hole internal diameter is littler than the internal diameter of nut, and is connected with the conical surface between the through hole of adapter body and internal thread 7 through holes; The outside thread 6 and the airexamination apparatus of valve body 2 one ends are connected to become relief opening, and the internal thread 7 of the other end is connected to become suction port with refrigerant water pipe or circulating pipe; Described test exhaust component comprise dress insert spool 1 in the valve body 2, be enclosed within spool 1 middle part seal ring 3, be contained in the nut and cross dish with internal thread 7 and cooperate and be fixed on the interior back-up ring 5 of valve body 2 and be enclosed within spool 1 lower end one end and withstand the spring 4 that spool 1, an end withstand back-up ring 5.
As shown in Figure 3, spool 1 inserts in the through hole of adapter body of valve body 2, can move up and down valve body 2 in, is contacted by seal ring 3 between spool 1 and the valve body 2, utilizes elastic force to make seal ring 3 contact closing seam with valve body 2 inner conical surfaces, is used for preventing that the interior water of pipeline from overflowing; Below spool 1 lower end, seal ring 3, become U-shaped crotch cover upper spring 4; It is exhaust port 1a that spool 1 middle part, seal ring 3 tops are provided with through hole, and the axial direction on spool 1 top has a upright opening to be communicated with exhaust port 1a.
When chilled water or water flow in refrigerant water pipe or circulating pipe, according to air in pipeline with water together, the proportion of air ratio water is much smaller, the reason that air is up walked when airexamination apparatus is tested, is pressed lower valve core 1, seal ring 3 leaves the conical surface, air in the pipeline just enters spool 1 from suction port through back-up ring 5, exhaust port 1a, sends to tester for test from relief opening again, by with airexamination apparatus testing conduit that outside thread 6 is connected in whether air is arranged; If air is arranged in the pipeline, do not need other operation, directly press lower valve core 1 and get final product, spool 1 is to lower slider, and pressure spring 4 moves down exhaust port 1a, main sectional view when spool is pressed as shown in Figure 4, the air in pipeline gives off outside the pipe in just injecting spool 1 from exhaust port 1a again.
