Abstract
The invention discloses a vacuum valve having opening and closing functions and relates to vacuum valves. The vacuum valve comprises a valve body, a vacuum opening arranged on the upper end of the valve body, a lower cover arranged on the lower end of the valve body, a water inlet formed on the lower cover, a bracket arranged on the inner side of the lower cover, a guide sleeve arranged on the bracket, a water opening arranged on the lower end of the guide sleeve, a float arranged inside the guide sleeve, a spring seat arranged below the float, a spring arranged between the spring seat and the float, an adjusting bolt arranged on the spring seat, and two electrodes arranged on one side of the valve body. Due to the two electrodes arranged on one side of the valve body, when the water level meets the requirement and the vacuum valve is closed, the water floods the two electrodes to turn on the electric loop to send electrical signals automatically so as to realize the automatic control of a primer pump and a main pump. Therefore, the vacuum valve is suitable for automatic water supply and fire equipment.
Description
Technical field
The present invention relates to vacuum valve, is a kind of vacuum valve with switching function specifically.
Background technique
We know, existing vacuum valve, be to be provided with vacuum port in the valve body upper end, valve body lower end is provided with lower cover, under cover and be provided with water intake, the lower cover inboard is provided with support, support is provided with guide sleeve, and the guide sleeve lower end is provided with the mouth of a river, is provided with float in the guide sleeve, the float below is provided with spring seat, be provided with spring between spring seat and the float, spring seat is provided with adjusting screw, and this vacuum valve is installed in the vacuum line, after water level reaches requirement, vacuum valve and closes, can not send the automatic control that electrical signal is realized priming pump and main pump automatically.
Summary of the invention
The technical problem that the present invention solves is that solution can not be sent the problem that electrical signal is realized the automatic control of priming pump and main pump automatically after water level arrival requirement, vacuum valve are closed.Provide a kind of after water level reaches requirement, vacuum valve and closes, can send the vacuum valve that electrical signal is realized the automatic control of priming pump and main pump automatically with switching function.
Technological scheme of the present invention is, is provided with valve body, and the valve body upper end is provided with vacuum port, valve body lower end is provided with lower cover, covers down and is provided with water intake, and the lower cover inboard is provided with support, support is provided with guide sleeve, the guide sleeve lower end is provided with the mouth of a river, is provided with float in the guide sleeve, and the float below is provided with spring seat, be provided with spring between spring seat and the float, spring seat is provided with adjusting screw, and the main structure characteristics are that valve body one side is provided with two electrodes.
The invention has the beneficial effects as follows that because valve body one side is provided with two electrodes, after water level reached requirement, vacuum valve and closes, two electrodes of water flooding can the conducting electric control circuit, can send the automatic control that electrical signal is realized priming pump and main pump automatically.The present invention is applicable to automatic water-supply and fire-protection equipment.
Description of drawings
Accompanying drawing is a kind of structural representation of the present invention, also is a kind of embodiment's schematic representation.
Embodiment
The vacuum valve with switching function as shown in the figure is provided with valve body 8, and valve body 8 upper ends are provided with vacuum port 10, valve body 8 lower ends are provided with lower cover 1, lower cover 1 is provided with water intake 2, and lower cover 1 inboard is provided with support 3, and support 3 is provided with guide sleeve 7, guide sleeve 7 lower ends are provided with the mouth of a river 11, be provided with float 9 in the guide sleeve 7, float 9 belows are provided with spring seat 5, are provided with spring 6 between spring seat 5 and the float 9, spring seat 5 is provided with adjusting screw 4, and valve body 8 one sides are provided with two electrodes 12,13.During use this valve is contained in the vacuum water diversion pipeline, vacuum port 10 is connected with vacuum pump, two electrodes 12,13 are connected on the electric control circuit, when degree of vacuum reaches certain value, will be entered in the valve from the water intake 2 of lower cover 1 by diversion, under the acting in conjunction of the elastic force of buoyancy of water and spring 6 and vacuum negative pressure, float 9 will rise rapidly and push down top vacuum port 10, at this moment two electrodes 12 of water flooding, 13, the conducting electric control circuit, electric control circuit can be controlled vacuum pump and stop immediately, and to controlled diesel engine unit or water supply, the fire-fighting main pump sends enabled instruction, and the present invention can realize that the vacuum pump after diversion puts in place stops automatically and supplies water, the purpose of the unlatching automatically of fire-fighting main water pump.
