Abstract
The utility model discloses an exhaust valve with a middle separator, which comprises a valve body and a valve cover. A protection cover is arranged on a cavity opening of a center step of the valve cover; a micro exhaust valve body is also arranged on the valve cover; a lower cavity opening is arranged at the bottom of a valve body communication cavity; the upper part of the lower cavity opening is connected with a sealing ring; a float ball in the valve body is pressed into the sealing ring under the action of the gravity of the float ball; the separator is also arranged in the valve body communication cavity above the float ball; the center of the separator is provided with a through hole; and a plurality of exhaust through holes are also arranged on the separator. The exhaust valve has simple structure, is easy to implement, can effectively avoid the problem that a float floats upward to block up the center communication cavity of the valve cover, and has a good exhaust effect.
Description
Technical field
The utility model relates to the outlet valve field, is specially a kind of outlet valve with intermediate clapboard.
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 stops up the valve gap central through bore live when gas pressure effect float downward sometimes, and gas in time is discharged from, and influences the proper functioning of outlet valve.
The model utility content
The utility model purpose provides a kind of outlet valve with intermediate clapboard, to solve the problem that the existing technology vent valve float can stop up the valve gap central through bore.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of outlet valve with intermediate clapboard 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 cavity bottom has the following accent of undergauge, and following accent top is connected with seal ring, but is provided with the ball float of free floating in the valve body; Said ball float its underpart under the self gravitation effect presses under the valve body cavity in the seal ring above the accent; The valve body cavity that is arranged in the ball float top also is provided with the dividing plate that separates the valve body cavity, and said dividing plate center has through hole, also is provided with a plurality of exhaust holes around the dividing plate central through bore on the dividing plate.
The utility model is simple in structure, is easy to realize.The valve body cavity is separated by the dividing plate of centre; The dividing plate center has central through bore, also is provided with the exhaust hole around central through bore on the dividing plate, during the float come-up; Can be pressed in the central through bore of dividing plate spacing by dividing plate; Gas continues to discharge from the exhaust hole on the dividing plate then, and float no longer floats, and therefore can not stop up the center cavity of valve gap.The utility model can effectively avoid the float come-up to stop up the problem of valve gap center cavity, has exhaust effect preferably.
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 intermediate clapboard; Comprise 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 3 mouthfuls in the step chamber, center 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 cavity bottom has the following accent 6 of undergauge; Following accent 6 tops are connected with seal ring 7; But be provided with the ball float 8 of free floating in the valve body 1, ball float 8 its underpart under the self gravitation effect presses under valve body 1 cavity in the seal ring 7 above the accent, and valve body 1 cavity that is arranged in ball float 8 tops also is provided with the dividing plate 9 that separates valve body 1 cavity; Dividing plate 9 centers have through hole 10, also are provided with a plurality of exhaust holes 11 around dividing plate 9 central through bores 10 on the dividing plate 9.
