Abstract

The utility model discloses an automatic exhaust valve. The automatic exhaust valve adopts a valve sealed mode, and comprises a housing, an exhaust valve plug, an exhaust valve, a conduit and a floating body. The automatic exhaust valve is characterized in that a cylindrical bump is formed on a base of the exhaust valve plug; conical inclined planes are formed between the cylindrical bump and the exhaust valve plug; the conical inclined planes are fit with inner inclined planes at the lower part of the exhaust valve conduit; and both the conical inclined planes and the inner inclined planes have the inclined angles of 45 DEG. Due to adoption of the technical scheme, the utility model has the advantages that the automatic exhaust valve has a simple structure; contact surfaces can be fit for a long time; and the service life is prolonged.

Description

Automatic control pressure vent

Technical field

The utility model discloses a kind of automatic control pressure vent.

Background technique

In the prior art from produce heating many with steam or hot water as heat transfer medium.In hot water supply system, be maintenance equipment proper functioning and energy saving, generally use stop valve or gate valve to get rid of steam and unsuspicious gas in the heating system, but this exhaust mode must manually start; Be difficult to operation, safety perhaps influences heat transfer efficiency because of exhaust is untimely inadequately; Therefore, some outlet valve changes automatic type into, and this float type automatic control pressure vent is operated exhaust in time automatically; Safe and reliable, present automatic control pressure vent adopts the pin type air-tight manner more, and working life is short; And phenomenons such as long-time practicality causes part aging, deforms, fracture cause serious consequence.

Summary of the invention

The utility model proposes a kind of automatic control pressure vent to existing problem in the above-mentioned existing technology, has adopted the air gate type air-tight manner, has reduced the wearing and tearing to installing in exhaust process, has prolonged working life, has increased device and has born pressure.

The utility model solves the problems of the technologies described above the technological scheme that adopted like following description:

A kind of automatic control pressure vent; Adopted the air gate type air-tight manner; Comprise shell, drain tap plug, drain tap, conduit and buoyancy aid, it is characterized in that: have cylindrical protrusion on the base of described drain tap plug, have conical inclined surface between cylindrical protrusion and the drain tap plug; The introversion inclined-plane of this conical inclined surface and exhaust valve guide bottom coincide, and described conical inclined surface is 45 with described tilt face tilt angle and spends.

The aperture of described exhaust valve guide is 3 millimeters, and wall thickness is 1 millimeter.

The diameter of described drain tap plug is 5 millimeters, and protrusion diameter is 2.5 millimeters.

The utility model the beneficial effect of having taked technique scheme such as below description;

This apparatus structure is simple, in long-term using process, through the thickening eroded area, can effectively reduce the wearing and tearing of exhaust process to each original paper, and can keep in touch surperficial anastomose property for a long time; About the pressure 4KG that existing product bore, can bear the pressure of 8KG after the improvement, improve the Security of device, prolong working life, and structural stability, should not rupture, be out of shape.

Description of drawings

Through the description of its exemplary embodiment being carried out below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the utility model will become apparent and understand easily.

Fig. 1 is the structural representation of a kind of automatic control pressure vent of the utility model.

Fig. 2 is the partial structurtes schematic representation of the utility model.

1 conduit wherein, 2 drain tap plugs, 3 shell upper bodies, 4 buoyancy aids, 5 shell lower bodies, 6 projections, 7 bases, 8 drain taps.

Embodiment

Carry out detailed description below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing.

This device has used the air gate type air-tight manner, and wherein shell upper body 3 fixedly mounts through screw with shell lower body 5, and exhaust valve guide 1 is arranged at 3 tops, shell upper body; Drain tap 8 is arranged under the drain tap conduit, and wherein the projection 6 of drain tap plug 2 is in drain tap conduit 1, and the base 7 of drain tap plug 2 is fixed on the buoyancy aid 4; Through improvement to outlet valve, make it in long-term exhaust process, antiwear property is strong; Should not deform, can prolong the life-span of single unit system.

It should be noted that; Above-mentioned specific embodiment is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.

It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection domain of the utility model is limited claim and equivalent thereof.
