Abstract
The utility model relates to a new automatic exhaust valve for a pipeline, which belongs to the field of an exhaust valve for a pipeline. The utility model comprises a valve body, a valve cover and a floating cup. The utility model is characterized in that a valve needle is arranged on the upper part of the floating cup; the upper part of the valve needle is a conical body; an exhaust hole corresponding to the conical body of the upper part of the valve needle is arranged in the center of the valve cover; a sealing groove is arranged on the side of the lower part of the valve cover; a sealing ring is arranged in the sealing groove. The valve cover and the valve body are in screw connection. An arc-shaped convexity is arranged on the side face of an outer circular cylinder of the floating cup; a concave notch is arranged on the lower part of the outer circular cylinder of the floating cup. Because the lower part of the valve cover adopts side seal, the sealing effect is good. The utility model can bear 1.0MPa pressure and can also ensure no water leakage under the condition of low pressure; the utility model has the advantages of ageing resistance, corrosion resistance and high durability. In addition, because of the arc-shaped convexity arranged on the side face of the outer circular cylinder of the floating cup and the concave notch arranged on the lower part of the floating cup, the stability of the floating cup can be increased; the utility model can also continuously or intermittently exhaust, for discharging gas in the pipeline. The utility model can be used for heating and for water pipelines of an air conditioning system.
Description
Technical field
The utility model belongs to the tube exhaust valve field, particularly a kind of novel pipeline automatic control pressure vent.
Background technique
In water heating system, the air that accumulates in the air-conditioning duct system is easy to generate the stifled phenomenon of gas, influence heat-transfer effect, this just need be provided with outlet valve in pipeline, present outlet valve is varied, a kind of " pipeline automatic control pressure vent " disclosed as Chinese patent 01248991.3, be characterized in not having link, sealingly secure, but this patent also exists complex structure, and the seal rubber pad on cursory in the outlet valve is easily aging, can't change, working life is short, outlet valve exhaust moment under low-pressure can leak, and cursoryly after the exhaust does not simultaneously fall, influence the secondary exhaust etc. problem.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and reliable operation is easy to change parts, can get rid of gas in the pipeline rapidly, good sealing effect, the novel pipeline automatic control pressure vent of long service life.
According to novel pipeline automatic control pressure vent of the present utility model, comprise valve body, valve gap, floating cup, it is characterized in that floating cup top is provided with needle, the top of needle is cone, the valve gap center is provided with and the corresponding exhaust port of needle top cone, be provided with seal groove in the bonnet lower side, be provided with seal ring in the seal groove.
Between described valve body and the valve gap for being threaded.
On described floating cup outer cylinder side, be provided with arc convex.
Arc convex on the described floating cup outer cylinder side is 3～6.
Arc convex on the described floating cup outer cylinder side is 4.
Be provided with concave indentation in described floating cup outer cylinder bottom.
The concave indentation quantity of described floating cup outer cylinder bottom is 2.
Novel pipeline automatic control pressure vent of the present utility model, its advantage is: simple in structure, can get rid of ducted gas rapidly, and can be continuously or be interrupted exhaust, can under the low pressure situation, guarantee watertight, good sealing effect, withstand voltage effect can reach 1.0MPa, and it is aging to be difficult for burn into, durable in use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of the floating cup of the utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1 and Figure 2, novel pipeline automatic control pressure vent of the present utility model, comprise valve body 6, valve gap 1, floating cup 7, it is characterized in that floating cup 7 tops are provided with needle 3, the top of needle 3 is cone, valve gap 1 center is provided with and the corresponding exhaust port 2 of needle 3 top cones, is provided with seal groove 4 in valve gap 1 lower side, is provided with seal ring 5 in the seal groove 4.Adopt between valve body 6 of the present utility model and the valve gap 1 and be threaded.Its objective is and be easy to change parts and sealing.
In order to strengthen the stability of floating cup, the utility model is provided with arc convex 8 on described floating cup 7 outer cylinder sides, and its arc convex 8 is generally 3～6, is preferably 4.
According to the utility model, also be provided with concave indentation 9 in described floating cup 7 outer cylinder bottoms.Its concave indentation 9 quantity are generally 2.The ducted gas effect of rapid eliminating can be reached like this, the purpose of continuous and discontinuous exhaust can be reached again.
Novel pipeline automatic control pressure vent of the present utility model is installed on the peak pipeline of heating and air-conditioning system, when having gas in the pipeline, gas is discharged by exhaust port 2 automatically, move when ducted water after the gas emptying will float on the cup 7; needle 3 on the floating cup 7 is sealed exhaust port 2 automatically, finish exhaust and stop water to flow out.
Evidence, novel pipeline automatic control pressure vent of the present utility model is owing to adopted side sealing in the bottom of valve gap 1, sealing effect is very good, can not only bear the pressure of 1.0MPa, and can also guarantee under the low pressure situation watertight, product never corrodes, not aging, durable in use, in addition owing on floating cup 7 outer cylinder sides, be provided with arc convex 8 and float the concave indentation 9 that the cup bottom is offered, can not only strengthen the stability of floating cup, get rid of ducted gas but also can continuously or be interrupted exhaust.The utility model can be widely used in the waterway pipe of heating and air-conditioning system.
