Abstract
The utility model discloses an exhaust valve structure with a guide column. The exhaust valve structure with the guide column comprises a valve body and a valve cover, a protective shield is installed on a step cavity mouth in the center of the valve cover, and the valve cover is further provided with a trace exhaust valve body. The side wall of a lower cavity mouth of the valve body extends upwards and forms a step cavity seat, the bottom of a floating ball in the valve body is connected with a gas nozzle, and a gas outlet is arranged on the side wall of the gas nozzle. The floating ball is pressed on the top of the step cavity seat, and the gas nozzle at the bottom of the floating ball is installed inside a sliding hole of the step cavity seat in a sliding mode. An annular fixing seat is disposed on the top of the floating ball, the inner wall at the bottom of the valve cover is provided with the guide column, and the annular fixing seat on the floating ball is installed on the guide column in a sliding mode. The exhaust valve structure with the guide column is simple in structure and easy to achieve, the accuracy can be effectively improved when the floating ball falls back, and the exhaust function can be timely quickly achieved, and thus the exhaust valve structure with the guide column has good exhaust effect.
Description
Technical field
The utility model relates to the outlet valve field, is specially a kind of exhaust structure with guide pillar.
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 with guide pillar, 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 with guide pillar 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 said cavity of resorption oral-lateral wall extends upward to the valve body cavity and constitutes step chamber seat, and step chamber seat top center is provided with slide opening; Also comprise the ball float that is arranged on the hollow in the valve body cavity; Ball float bottom be connected with ball float in the valve that is communicated with, the valve sidewall is provided with a plurality of air outlets, said ball float is pressed in seat top, step chamber and blocks the slide opening of step chamber seat under the self gravitation effect; And the valve of ball float bottom is slidingly mounted in the slide opening of step chamber seat; The ball float roof anchorage is equipped with annular fixed seat, is separately installed with guide pillar on the valve gap bottom interior wall of ball float both sides, and the annular fixed seat on the said ball float is slidingly mounted on two guide pillars.
The utility model is simple in structure, is easy to realize.The valve of ball float bottom is slidingly mounted in the slide opening of step chamber seat, and gas is introduced in the ball float during exhaust, makes ball float float, and valve also rises along with ball float, exposes from the seat of step chamber until the air outlet of valve sidewall, so just can gas be discharged.On the valve gap bottom interior wall guide pillar is installed; Annular fixed seat and ball float on the ball float are fixed as one; Annular fixed seat is slidingly mounted on the guide pillar simultaneously, moves along guide pillar when ball float receives the gas pressure come-up, can accurately be pressed in accent place, valve body cavity bottom when ball float falls after rise like this.Validity when the utility model can effectively improve the ball float falling, and can in time realize having exhaust effect preferably by degassing function apace.
