Abstract
The utility model relates to an automatic exhaust valve for water central heating. A rubber port is closed by a metallic ball near the supporting point of a lever. Mutual contact area is small, and simultaneously the tension of a pressure spring and the interaction of floats are utilized to obtain the aims of opening and closing stress firmly, equally, sensitively, conveniently and reliably, and gas-liquid separation is accelerated. The automatic exhaust valve for water central heating is suitable for exhausting accumulated air in water heating pipe network systems, and the heat supply efficiency of the pipe network is increased.
Description
The utility model belongs to a kind of mechanical valve, is applicable in the liquid network circulating line, particularly gets rid of air accumulation in the water heating network system.
The hot-water heating automatic control pressure vent in practice, the most frequently used problem is: valve seal is not tight, exhaust rate is low, easy to failure, cause exhaust band water easily, pollute living environment etc., lose the due effect of product, the utility model is in former CN2062391U, the enterprising improvement in basis of CN2074864U patent.
It is fast that the purpose of this utility model provides a kind of gas collection, and sealing force is balanced more, corrosion-resistant, open and close more flexibility and reliability, the high speed closed type hot-water heating automatic control pressure vent that practicability is high.
The utility model has been taked following technical measures, and valve lever 8 one ends and float 13 link, and the other end interacts by stage clip 4 and valve gap 9, and the fulcrum of valve lever 8 links with the ear that connects on the valve gap 9 by attachment pegs 6.Valve lever 8 fulcrums are provided with one nearby and open and close the sealing metal spheroid, itself and the keying exhaust passage that interacts in the sealing rubber ring 5 that is installed in valve gap 9.The upper end of valve gap 9 is a square nut, so that valve gap 9 and the stubborn of valve body 15 close, has exhaust nozzle 23 in the square nut, by fastening piece (screw 1), on square nut, be fixed with the plasticity return-air cap that a diameter is slightly larger than square nut diagonal distance, dash with gas-tight and spatter, pollute the room metope.Link in valve body 15 bottoms and gas-liquid separator 21.Gas-liquid separator 21 bottoms and sidepiece respectively are provided with a logical screw socket, directly incorporate with water inlet and outlet pipe network system linking respectively into.
The utility model has advantage compared to existing technology, and the sealing of valve exhaust nozzle is made up of spring and spherical metal and sealing rubber ring, and it is little to reach sealing contact surface, and is strong, balanced, firm.Float and lever rely on buoyancy of water, and the air water lifting changes, and plays down
Hang down to opening and chew exhaust, float closing function.Connect gas-liquid separator at the bottom of the valve, overcome and rely on the nature pneumatosis in the past, reach the pressure gas collection, improve the gas collection rate, reduce pipe network gas-liquid mixed flow.The without hindrance circulation of liquid is unimpeded etc.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is that the high speed closed type is from hot-water heating automatic control pressure vent sectional view
Accompanying drawing 2 is that the high speed closed type is from hot-water heating automatic vent valve gap 9 attached views
Accompanying drawing 3 is that the high speed closed type is from the attached view of hot-water heating automatic control pressure vent gas-liquid separator
Label declaration:
1, screw; 2, return-air cap; 3, stage clip position limit socket; 4, stage clip; 5, sealing rubber ring; 6, lever pin; 7, sealing copper ball; 8, lever; 9, valve gap; 10, float is hung pin; 11, hang the pin rubber ring; 12, sealing rubber ring; 13, float upper body; 14, float lower body; 15, valve body; 16, sealing rubber ring; 17, secondary sealing pin; 18, spring; 19, secondary sealing copper band; 20, secondary sealing rubber ring; 21, gas-liquid separator; 22, interior hexagonal clamping bolt; 23, exhaust nozzle.
Its working principle is: liquid top institute coproduct is deposited gas by the heterogeneous position of the turning one's coat setting-out bit line decline because gas increases that reduces in valve, and float is owing to also descend with water line from hanging down.Lever 8 is under the float traction, drive sealing copper ball 7, also move down thereupon, break away from rubber ring 5 endoporus, decontrol valve and chew exhaust, the other end stage clip 4 inevitable pressurizeds of lever 8 store certain elastic force simultaneously, when gas is discharged to certain position, water level is with rising, float drives lever 8 with water level and moves up, meanwhile stage clip 4 also will be opened reduce to press the outside Shen of storage power, must increase lever 8 and quicken upwards to move power, and value is adjacent to sealing rubber ring 5 inner orifices for extremely to sealing copper ball garden loop-drive under dual mutual power effect, promptly reach and tightly close exhaust port and stop exhaust, count with this and push away circulation.Valve body 15 bottoms and gas-liquid separator 21 link, a screw oral pore is respectively stayed in gas-liquid separator side and bottom, connect with the water inlet and outlet pipe network respectively, force that liquid must be through gas-liquid separator 21 in the pipeline, because gas-liquid separator slows down flow rate of liquid, the imbalance of gas-liquid proportion, make it mixed flow gas separation in the middle of liquid, because gas-liquid is all sought to reduce pressure direction and moved under certain pressure, to alleviate common pressure, flowing fluid ratio gas is heavy, has only flow ipe circulation under forced draught, specific gravity of gas is light, has only upwards to float under pressure and wait for discharge in entering outlet valve, staticizes liquid thereby reach, reduce the gas-liquid mixed flow, it is stifled to avoid reducing gas, and unimpeded acceleration liquid circulation improves heat input rate.
Claims (3)
1, a kind of high speed closed type hot-water heating automatic control pressure vent, comprise that valve body, float, valve are chewed, gas-liquid separator is formed, it is characterized in that valve lever 8 one ends and float link, the other end interacts by stage clip 4 and valve gap 9, and the fulcrum of valve lever 8 links with the ear that connects on the valve gap 9 by attachment pegs 6.Valve lever 8 fulcrums are equipped with one nearby and open and close the sealing metal spheroid, interact with the sealing rubber ring 5 that is installed in the valve gap 9, open and close the exhaust passage.Valve body 15 lower ends link 21 two mouthfuls of gas-liquid separators respectively as incorporating water inlet and outlet pipe network system into.
2, high speed closed type hot-water heating automatic control pressure vent as claimed in claim 1, it is characterized in that: the upper end valve exhaust of valve gap 9 is chewed, and is fixed with the plasticity envelope gas cap that a diameter is slightly larger than nut diagonal distance by fastening piece.
3, as the airtight hot-water heating automatic control pressure vent of right 1 described high speed, it is characterized in that: in the gas-liquid separator 21 that valve body 15 lower ends connect the automatic enclosed construction structure of secondary is housed.
