Description
Technical field
The utility model relates to a kind of outlet valve, specifically is a kind ofly to be used to heat or the ducted pipeline automatic control pressure vent of refrigeration system.
Background technique
Automatic control pressure vent generally is applied to the exhaust of pipelines such as independent heating system, central heating system, heating boiler, central air-conditioner, floor heating and solar heating system.This be since in heating or refrigeration system because the variation of water temperature and pressure, can discharge a large amount of gas in the system, part gas can be dissolved in the water, promptly the form with bubble exists, and can cause reduction, the system of system thermal efficiency problems such as noise, corrosive pipeline, local superheating or not hot, components and parts damage to occur like this.Along with the rising of temperature, the bubble in the water can be separated from water gradually, and accumulates in the pipeline top gradually and form big bubble.Therefore, outlet valve is installed at the pipeline top usually, is opened outlet valve in good time, the bubble in the pipeline is released, thus the normal operation of the system of assurance.
The automatic control pressure vent of prior art generally includes valve seat, valve gap, float and valve body, one end of valve seat is connected with pipeline, the other end is connected with valve gap, cavity of the common formation of valve base cavity and valve gap inner chamber, one end of float is connected with valve body, the other end moves back and forth along axial direction in cavity, and valve body is connected in the valve gap.But there is following shortcoming in the automatic control pressure vent of this structure:
1) owing on the valve seat valve body both had been installed, again with system in intake pipe be connected with outlet pipe, therefore the relative position of intake pipe and outlet pipe and valve body is fixed, angle is also fixed, like this, when the as installed situation needs repairing when changing outlet valve, whole automatic control pressure vent be pulled down from the intake pipe of system and outlet pipe, therefore, dismounting is very inconvenient.
2) again because valve seat is connected with intake pipe and outlet pipe, intake pipe and outlet pipe are to be on the same axis generally speaking, in other words, current lead directly to from the intake pipe to the outlet pipe, like this, are easy to make a part of bubble in the current can't go to the valve body place, but along with current enter in the system, therefore, the exhaust effect of this structure is also bad, thereby influences the normal operation of system.
The model utility content
Technical problem to be solved in the utility model is, dismounting pipeline automatic control pressure vent very easily when a kind of maintenance is provided.
For solving the problems of the technologies described above, a kind of pipeline automatic control pressure vent that the utility model provides, comprise valve seat, valve gap, ball float and valve body, described valve seat is connected with valve gap and forms an inner chamber in inside, described ball float is slidingly fitted in the inner chamber, and ball float is connected with valve body by pull bar, and described valve body is connected in the valve gap, and described valve seat is by the removable connecting tube that can be fitted with intake pipe and outlet pipe that is connected with of connection set.
Described connection set comprises attaching nut and collar, and described collar is connected on the connecting tube, and described attaching nut's threaded one end is connected the end of valve seat, the other end and collar chucking.
The joint end face of described connecting tube and valve seat has seal ring.
After adopting above structure, the utility model compared with prior art, has following advantage: owing to be removable the connection at valve seat and the connecting tube that can be fitted with turnover water pipe, like this when the maintain and replace outlet valve, need not pull down from turnover water pipe, the valve seat that only needs to have gas outlet valve is pulled down and is got final product, and dismounting is very convenient during maintenance.
As improvement, have valve seat dividing plate and connecting tube dividing plate in described valve seat and the connecting tube respectively, described valve seat dividing plate is positioned at the centre of valve seat, and described connecting tube dividing plate is between two ports that link to each other with turnover water pipe respectively, and described valve seat dividing plate and connecting tube dividing plate join.After adopting this structure, owing between water inlet port and water outlet port, be provided with dividing plate, can not directly go out after making the interior current of pipeline enter in the valve seat from the water outlet port, in the runner that constitutes by dividing plate, flow, and make the filtration of in flowing, having passed through gas, make from the current that valve seat water outlet port is gone out and contain less bubble, thereby make exhaust effect better, and then the normal operation of the system of assurance.
As further improvement, be provided with spiral helicine metal separation net in the described inner chamber, described metal separation net is positioned at the below of ball float.Described valve body comprises valve rod, sealing block, valve body end cap, gas outlet valve and spring, one end and the pull bar of described valve rod are hinged, the other end end is embedded with sealing block, the end face of the end face of sealing block and valve body end cap one end is rotatably assorted, valve body end cap is connected in the valve gap, the other end of valve body end cap is connected with gas outlet valve, and described spring housing is connected on valve rod and the valve body end cap.The end face of described sealing block is the cambered surface of indent, and the end face of described valve body end cap is the outer convex globoidal that matches with inner concave arc surface.After adopting this structure, owing in inner chamber, be provided with the multiple layer metal separating grid, on the one hand, bubble in these metal separation nets meeting adsorbed water, thereby these metal separation nets are stopped current and are caused turbulence state on the other hand, make by the water velocity at this place slack-off, it is big that resistance becomes, thereby helping discharging is adsorbed on the online bubble of metal separation, owing to becoming, volume breaks away from greatly in the exhaust cabin that wire netting rises to the ball float place after these bubble coalescence, bubble emission effect in the current is better like this, thus the normal operation of the system of assurance, and utilize the centrifugal settling principle of spiral to make gas and liquor separation better.
As further improving, described valve seat is connected to FERRULETYPE with intake pipe and outlet pipe and is connected, this joint comprises cutting ferrule nut and snap ring, described cutting ferrule nut is threaded with the valve seat port, described snap ring is between cutting ferrule nut and valve seat port, and an end of snap ring and the inside trumpet mouth of valve seat port push against, and the inner conical surface of the other end and cutting ferrule nut pushes against.As improving further, the outer surface of described snap ring is a sphere again.After adopting this structure, operate simplyr, only need tighten or unscrew the cutting ferrule nut, just can realize the installation and removal of intake pipe and outlet pipe, therefore, very time saving and energy saving.
