Abstract
The utility model relates to an ultrahigh pressure difference water supply regulating valve comprising an executing mechanism, a valve body, a valve cover, a valve clack, an upper and a lower pressure reducing component and a pressure reducing hole plate, wherein the upper end of the valve body is fixedly provided with the valve cover; the executing mechanism passes through the valve cover to be connected with the valve clack; the valve clack is installed in the channel of the valve body; the upper pressure reducing component is fixed between the water inlet and an inner channel of the valve body; the lower pressure reducing component is fixed between the water outlet and the inner channel of the valve body; and the pressure reducing hole plate is fixed on the wall of the inner channel of the valve body. The ultrahigh pressure difference water supply regulating valve is simple in structure, reliable in operation, strong in regulating capacity and durable.
Description
Technical field
The water that the utility model relates to hyperpressure is depressured to the system that the normal pressure collection is recycled again, is specifically related to a kind of superhigh pressure difference feed-regulating valve.
Background technique
In fields such as oil, thermoelectricity, because of arts demand, the water of hyperpressure is depressured to normal pressure, and (0.1 ~ 1.0MPa) collects and recycles.In the prior art, usually adopt two common feed-regulating valves of series connection, the water of hyperpressure is depressured to normal pressure.Because common modulating valve decompression progression few (generally having only 1 ~ 2 grade), so every grade has been born great pressure drop, and flash distillation and cavitation phenomenons often take place, and has both made the working life of valve very short, pressure surge greatly also is difficult to control in the operating process, also usually sends vibrations and noise.
Summary of the invention
For fear of the effective means that flash distillation and cavitation phenomenons take place is to manage to limit the pressure drop of every grade in modulating valve, and the purpose of this utility model provides a kind of superhigh pressure difference feed-regulating valve.
To achieve these goals, the utility model is by the following technical solutions:
The superhigh pressure difference feed-regulating valve has designed two mazy type decompression members (every mazy type decompression member has the level Four decompression) and the decompression of Pyatyi orifice plate up and down, by the flap change actual internal area that moves up and down, carrying out flow and pressure regulates, every grade of pressure drop of only bearing about 1.0 ~ 2.0MPa, avoid the generation of flash distillation and cavitation phenomenons effectively, operate easily steadily, can not send vibrations and noise, prolong the working life of valve greatly
The superhigh pressure difference feed-regulating valve, it comprises actuator, valve body, valve gap, flap, two decompression members and pressure reducing orifice up and down, the valve body upper end is valve gap fixedly, actuator wears valve gap and is connected with flap, flap is installed in the passage of valve body, last decompression member is fixed between valve inleting water mouth and the internal channel, and following decompression member is fixed between valve body water outlet and the internal channel, and pressure reducing orifice is fixed on the internal channel wall of valve body.
Superhigh pressure difference feed-regulating valve working principle, the mazy type decompression member above the water of hyperpressure flows in the valve body by the valve inlet end, the pressure reducing orifice of flowing through again by following mazy type decompression member, flows out valve body.When flap was in zero-bit, the conical surface of flap compressed the conical surface of the first plate pressure reducing orifice, and runner is blocked fully, and valve is in closed condition.When flap moved upward, runner was opened, and valve is in throttle; When continuing to move up to total travel, the whole turn-on flow rate maximums of valve.
The superhigh pressure difference feed-regulating valve simple in structure reliable, regulating power is strong, durable in use.

Fig. 1 is the utility model structural representation.
Specific embodiments
Further specify below in conjunction with accompanying drawing:
As shown in Figure 1, the superhigh pressure difference feed-regulating valve, it comprises actuator, valve body 2, valve gap 3, flap 4, two decompression members 5,1 and pressure reducing orifice 6 up and down, valve body 2 upper ends are valve gap 3 fixedly, actuator wears valve gap 3 and is connected with flap 4, and flap 4 is installed in the passage of valve body 2, and last decompression member 5 is fixed between valve body 2 water intakes and the internal channel, following decompression member 1 is fixed between valve body 2 water outlets and the internal channel, and pressure reducing orifice 6 is fixed on the internal channel wall of valve body 2.
