Abstract
The utility model discloses an exhaust valve with a plug. The exhaust valve comprises a valve body and a valve cover, wherein the top of the valve cover is provided with a central step orifice; a plug is arranged in the central step orifice of the valve cover in a sliding way; the bottom end of the plug extends into a through cavity of the valve body, and an annular step is molded on the side wall of the bottom end of the plug; a spring is connected between the inner wall of the top of the valve body and the annular step at the bottom end of the plug; the exhaust opening of a central exhaust hole in the plug is formed on the side wall of the plug; the bottom of the valve body is provided with a lower orifice; a sealing ring is arranged above the lower orifice; a floater is pressed against the sealing ring; and a plurality of carrier rods are connected to the top of the floater. The exhaust valve is simple in structure, and is easy to realized; and the floater can be reset in time, and the performance of the exhaust valve is improved.
Description
Technical field
The utility model relates to the outlet valve field, is specially a kind of outlet valve with obstruction.
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, vent valve float is behind gas pressure effect float downward, and often return speed is slower, influences the proper functioning of outlet valve.
The model utility content
The utility model purpose provides a kind of outlet valve with obstruction, to solve the slow-footed problem of existing technology vent valve float return.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of outlet valve with obstruction 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; The top of valve gap has center step accent, it is characterized in that: be slidingly fitted with the obstruction of blocking valve gap center step accent in the step accent of said valve gap center, the obstruction bottom is stretched in the valve body cavity and is stopped up the bottom sidewall and forms ring-shaped step; Be connected with spring between the ring-shaped step of said valve body top inner wall and obstruction bottom; Have the center vent in the said obstruction, and the relief opening that stops up vent is arranged on and stops up on the sidewall, said valve body bottom has the following accent of undergauge; Following accent top is connected with seal ring; But be provided with the float of free floating in the valve body cavity, said float is pressed on the seal ring under the self gravitation effect, and the float top is connected with a plurality of vertical replacing at the push rod that stops up on the bottom.
The utility model is simple in structure, is easy to realize.Be provided with in the valve gap slidably and stop up; Float is floated by gas pressure during exhaust, and the push rod at float top will stop up upwards top, and the relief opening of vent exposes from valve gap in stopping up; Thereby carry out exhaust; Be blocked in after exhaust finishes under gravity and the spring action and glide, and replace the push rod at float top, be pressed on the seal ring thereby float can in time be reset to.Float can in time reset in the utility model, 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 with obstruction 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; The top of valve gap 2 has center step accent 3, is slidingly fitted with the obstruction 4 of blocking valve gap 2 center step accents 3 in the valve gap 2 center step accents 3, stops up 4 bottoms and stretches in valve body 1 cavity and stop up 4 bottom sidewalls and form ring-shaped step 5; Be connected with spring 6 between the ring-shaped step 5 of valve body 1 top inner wall and obstruction 4 bottoms; Stop up in 4 and have center vent 7, and the relief opening that stops up vent 7 is arranged on and stops up on 4 sidewalls, valve body 1 bottom has the following accent 8 of undergauge; Following accent 8 tops are connected with seal ring 9; But be provided with the float 10 of free floating in valve body 1 cavity, float 10 is being pressed under the self gravitation effect on the seal ring 9, and float 10 tops are connected with a plurality of vertical replacing at the push rod 11 that stops up on 4 bottoms.
