Abstract
The utility model discloses an exhaust valve structure, which comprises a valve body 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; a floating ball is arranged in a valve body through cavity; the bottom of the floating ball is pressed against the lower orifice of the valve body through cavity; a carrier rod is connected to the center of the top of the floating ball; an installation base is fixed in the central through cavity of the valve cover; a guide rod is arranged in the center of the installation base in a sliding way; the lower end of the guide rod is connected with a valve clack; the centers of the guide rod and the valve clack are provided with central through cavities; and the top end of the carrier rod of the floating ball is aligned with and arranged close to the lower orifices of the central through cavities of the guide rod and the valve clack. The exhaust valve structure is simple in structure, and is easy to realize; and the falling accuracy of the floating ball can be increased effectively, and the performance of an exhaust valve is further improved.
Description
Technical field
The utility model relates to the outlet valve field, is specially a kind of exhaust structure.
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, the position valve body lower portion accent that can squint sometimes when vent valve float falls after rise causes outlet valve to lose efficacy.
The model utility content
The utility model purpose provides a kind of exhaust structure, the problem that deviation can cause outlet valve to lose efficacy occurs to solve existing technology vent valve float falling position.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of exhaust structure 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, and on the center step accent of valve gap the protective housing of blocking center step accent is installed, and 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: but be provided with the ball float of free floating in the said valve body cavity; Said ball float is pressed in accent place, valve body cavity bottom at self gravitation effect lower bottom part, and the ball float top center is connected with vertical push rod, and said valve gap center cavity internal fixation is equipped with fitting seat; The fitting seat central slide is equipped with along the guide rod that vertically stretches in the valve body cavity; Lower end of the guide rod is connected with flap, and guide rod, flap center be provided with the center cavity that supplies ball float top push rod to get into, and the top of said ball float push rod is aimed at and near the bottom accent of guide rod, flap center cavity.
Described a kind of exhaust structure is characterized in that: form circular groove on the said bonnet lower capping, be provided with in the circular groove and be enclosed within the outer ring packing packing ring of guide rod.
The utility model is simple in structure, is easy to realize.The center cavity of guide rail, flap supplies the push rod at ball float top to stretch into; Like this after the ball float come-up; Utilize to cooperate between push rod and guide rod, the flap center cavity and realize the location, ball float can be fallen after rise to blocking the valve body lower portion accent fully along the direction of guide rod, flap and push rod location.The validity that the utility model can effectively improve ball float when falling after rise, and then 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 exhaust structure 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, and on the center step accent 3 of valve gap 2 protective housing 4 of blocking center step accent 3 is installed, and the micro-exhaust valve 5 that is communicated with valve body 1 cavity also is installed on the valve gap 2; But be provided with the ball float 6 of free floating in valve body 1 cavity; Ball float 6 is pressed in accent place, valve body 1 cavity bottom at self gravitation effect lower bottom part, and ball float 6 top center are connected with vertical push rod 7, and valve gap 2 center cavity internal fixation are equipped with fitting seat 8; Fitting seat 8 central slide are equipped with along the guide rod 9 that vertically stretches in valve body 1 cavity; Guide rod 9 lower ends are connected with flap 10, and guide rod 9, flap 10 centers be provided with the center cavity that supplies ball float 6 top push rods 7 to get into, and the top of ball float 6 push rods 7 is aimed at and near the bottom accent of guide rod 9, flap 10 center cavities.Form circular groove on the valve gap 2 bottom cappings, be provided with the ring packing packing ring 11 that is enclosed within outside the guide rod 9 in the circular groove.
Claims (2)
