Abstract
Disclosed is a controlling mechanism of a lowest liquid elevating valve, which is used for hydraulic presses and high-pressure water descaling water pump stations. The controlling mechanism comprises the lowest liquid elevating valve and an electro-magnetic valve, wherein the lowest liquid elevating valve is provided with a controlling chamber, a balance chamber, a high-pressure chamber and an outlet chamber, the ring-shaped controlling chamber and the balance chamber are connected with the electro-magnetic valve respectively via a pipe passage and a water supply main valve, the high-pressure chamber is connected with a high-pressure water canister, and the outlet chamber is connected with a high-pressure water pump. The utility model with simple structure and relatively low cost has the advantages that time spent on closing and cutting off water supply from the high-pressure canister to a system is less than 1 second, and the main valve can be started only under the dual conditions that the electro-magnetic valve is energizing and the high-pressure water pump is inputting high-pressure water, thereby openness and closeness is reliable.
Description
Technical field
The utility model relates to the valve technology field, especially relates to a kind of liquid level control valve of high pressure water pot.
Background technique
The minimum level valve is widely used on hydraulic press and the high-pressure water descaling pumping station, and existing minimum level valve is a kind of direct control type duty valve, controls two valve distributors with Breake Electromagnet, controls the minimum level valve again; This control mechanism can be realized direct commutation function, but mechanism's complexity, cost height, poor reliability, is easy to generate that the high pressure water pot is metalled run out and the deflation phenomenon.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, and a kind of control mechanism of simple in structure, the reliable minimum level valve of opening and closing is provided.
For achieving the above object, the technical solution adopted in the utility model is such: a kind of control mechanism of minimum level valve, comprise minimum level valve and solenoid valve, said minimum level valve is provided with control chamber, counter balance pocket, hyperbaric chamber and outlet plenum, wherein control chamber is a ring-type, and control chamber and counter balance pocket reach water supply main valve and solenoid valve respectively by the road and join; Hyperbaric chamber and high pressure water pot join; Outlet plenum connects high-pressure water pump.
Working procedure of the present utility model is such: when control system is given the solenoid valve power on signal, electromagnetic valve liquid flows to into the control chamber of minimum level valve and counter balance pocket, in control chamber and counter balance pocket under the acting in conjunction of fluid pressure, main valve is closed rapidly, the time of main valve closing motion was enough to escaping of anti-sealing, gas less than 1 second; When control system is given the solenoid valve power-off signal, electromagnetic valve minimum level valve control chamber liquid stream flows out, the pipeline release of joining with main valve; While is exported high pressure water with the high-pressure water pump that outlet plenum joins, and this moment, main valve was just opened.
Owing to adopted technique scheme, the control mechanism of a kind of minimum level valve of the present utility model, make close and the cutoff high jar to time of system water supply less than 1 second; Main valve is opened to be needed could move under the double condition of solenoid valve energising and high-pressure water pump output high pressure water, thereby opening and closing are reliable, and simple in structure, and manufacture cost is lower.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, solenoid valve, 2, counter balance pocket, 3, control chamber, 4, hyperbaric chamber, 5, outlet plenum.
Embodiment
By shown in Figure 1, the control mechanism of a kind of minimum level valve of the present utility model, comprise minimum level valve and solenoid valve 1, said minimum level valve is provided with control chamber 3, counter balance pocket 2, hyperbaric chamber 4 and outlet plenum 5, wherein control chamber 3 is a ring-type, and control chamber and counter balance pocket reach the water supply main valve by the road respectively and solenoid valve 1 joins; Hyperbaric chamber and high pressure water pot join; Outlet plenum connects high-pressure water pump.
