The invention discloses a vacuum suppressor applied in non-negative pressure water supply equipment. The vacuum suppressor comprises a valve sleeve, a movable vent valve, a locating sleeve, a spring, a valve cover, a solenoid valve and an outer protection cover, wherein a first venting through hole and a first guiding hole arranged on the bottom part of the valve sleeve; a second venting through hole is arranged on a side wall of the valve cover; the movable vent valve is provided with a seal plate and a vent valve core connected with the seal plate; the seal plate is fit to the bottom part of the valve sleeve and covers the first venting through hole; the spring is accommodated in a cavity of the valve sleeve, and is sleeved on the vent valve core; the locating sleeve is fixed on the vent valve core and is arranged on the upper part of the spring; the valve cover is arranged on an opening part of the cavity of the valve sleeve, and is provided with a second guiding hole communicated with the cavity of the valve sleeve; the solenoid valve is arranged on the valve cover, and is provided with a solenoid valve core; and the outer protection cover is coated on the peripheries of the valve sleeve and the solenoid valve. The vacuum suppressor can suppress the generation of negative pressure, has good sealability, and is stable and reliable to operate.
Description
technical field [0001] The invention relates to a vacuum suppressor, in particular to a vacuum suppressor used in non-negative pressure water supply equipment. Background technique [0002] The vacuum suppressor is the technical core component of the non-negative pressure water supply equipment to realize the non-negative pressure function. The vacuum suppressor is generally installed on the voltage regulator of the water supply equipment. The exhaust and air compensation functions of the vacuum suppressor are to realize the pressure regulator The key to the technology of no negative pressure, therefore, the reliability and stability of the structural performance of the vacuum suppressor directly affects the reliability and stability of the entire non-negative pressure water supply equipment. [0003] Existing vacuum suppressors generally control the opening and closing of the valve by the water level rise and fall in the voltage stabilizer regulator and the float moves up a...
