Abstract
The utility model discloses an exhaust valve, which comprises a valve body with a through cavity, and a valve cover connected to the top of the valve body, wherein a protective cover is arranged on a central step orifice on the top of the valve cover; a trace exhaust valve body is further arranged on the valve cover; an inner container is arranged on the inner wall of the lower part of the valve body; a conical orifice is molded upwards at the bottom of the inner container; a floating ball is arranged in the inner container; and the floating ball is pressed against the upper conical surface of the bottom conical orifice of the inner container. The exhaust valve is simple in structure, and is easy to realize. The bonding airtightness between the floating ball and the lower orifice of the valve body can be enhanced effectively, and the performance of the exhaust valve is further improved.
Description
Technical field
The utility model relates to the outlet valve field, is specially a kind of outlet valve.
Background technique
Water heating system generally adopts water as the medium that transmits heat; Usually be dissolved with certain air in the water; When water temperature raise, the gas in the water can be separated from water gradually, and get together gradually formation big bubble even gas column; Therefore, generally need in the water heating system to adopt outlet valve that the gas in the water is discharged.Outlet valve generally by valve body be arranged on float in the valve body etc. and constitute; Gas is from valve body lower portion accent entering valve body and make the float come-up of blocking the valve body lower portion accent to realize exhaust, and the valve body lower portion accent was blocked in float falling under action of gravity again after exhaust finished.In the existing technology, owing to airtightly combine not thoroughly, the problem that often leaks air influences the proper functioning of outlet valve between vent valve float and the valve body lower portion accent.
The model utility content
The utility model purpose provides a kind of outlet valve, is prone to the problem that gas leakage influences the outlet valve proper functioning to solve the existing technology outlet valve.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of outlet valve comprises the valve body with cavity, and flange is tightly connected at the valve gap at valve body top; Valve gap has the center cavity, and the top of valve gap has center step accent, and on the center step accent of valve gap the protective housing of blocking center step accent is installed; The micro-exhaust valve that is communicated with the valve body cavity also is installed on the said valve gap; It is characterized in that: said valve body lower portion inwall is provided with inner bag, and the inner bag bottom is positioned at the following accent place of valve body cavity, and the inner bag bottom upwards forms the taper accent; But be provided with the ball float of free floating in the inner bag, said ball float self gravitation effect lower bottom part be pressed in inner bag bottom taper accent on the conical surface.
Described a kind of outlet valve; It is characterized in that: the bottom has the bench port of undergauge in the said micro-exhaust valve; Be positioned at bench port in the trace exhaust valve and be provided with the rubber column that can get lodged on the bench port; Trace exhaust valve top has valve port, and is provided with exhaust bolt in the valve port of micro-exhaust valve top.
The utility model is simple in structure, is easy to realize.Valve body cavity inwall bottom is provided with inner bag; The inner bag bottom has the taper accent that upwards is provided with; Be pressed under the ball float on the taper accent epicone face of inner bag; The last conical surface through the taper accent cooperates with ball float sphere bottom, can effectively improve the tightness that combines between ball float and the valve body lower portion accent, and then has improved the performance of outlet valve.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1.A kind of outlet valve comprises the valve body 1 with cavity, and flange is tightly connected at the valve gap 2 at valve body 1 top; Valve gap 2 has the center cavity, and the top of valve gap 2 has center step accent 3, and on the center step accent 3 of valve gap 2 protective housing 4 of blocking center step accent 3 is installed; The micro-exhaust valve 5 that is communicated with valve body 1 cavity also is installed on the valve gap 2; Valve body 1 lower inner wall is provided with inner bag 6, and inner bag 6 bottoms are positioned at the following accent place of valve body 1 cavity, and inner bag 6 bottoms upwards form taper accent 7; But be provided with the ball float 8 of free floating in the inner bag 6, ball float 8 self gravitation effect lower bottom part be pressed in inner bag 6 bottom taper accents 7 on the conical surface.
The bottom has the bench port of undergauge in the trace exhaust valve 5; Be positioned at bench port in the trace exhaust valve 5 and be provided with the rubber column 9 that can get lodged on the bench port; Trace exhaust valve 5 tops have valve port, and are provided with exhaust bolt 10 in the micro-exhaust valve 5 top valve ports.
