Abstract
The utility model relates to a water-saving valve. The water-saving valve comprises a valve body, a water inlet end, a water drain end, a water inlet and a water outlet, wherein the water inlet end is mounted at one side of the valve body; the water drain end is mounted at the other side of the valve body; the water inlet is located at the inner side of the water inlet end; the water inlet end is formed with an internal thread; the water outlet is located at the inner side of the water drain end; the water drain end is formed with an external thread. The inner diameter of the water inlet is greatly larger than that of the water outlet. Since the inner diameter of the water inlet is greatly larger than that of the water outlet, when the water flows into the water inlet tube from the water inlet, the water is slowed down to pass through the water-saving valve and can be used as a water cooling water source. The water-saving valve is simple in structure, is convenient to use, and is safe and reliable.
Description
Technical field
The utility model relates to drainage machinery field, specifically a kind of water-saving valve.
Background technique
Submersible pump refers to the pump of working environment below the water surface, it must be full of liquid in suction pipe and pump, after turn on pump before turn on pump, impeller High Rotation Speed, liquid wherein, along with blade rotates together, under the effect of centrifugal force, flies away from impeller and outwards penetrates, the liquid speed in pump case explosion chamber penetrating is slack-off gradually, pressure increases gradually, and then from pump discharge, discharge tube flows out.Now, in blade center, because being thrown toward, liquid around forms the vacuum low-pressure district that not only there is no air but also there is no liquid, liquid in liquid pool is under the atmospheric effect of pond face, in suction pipe inflow pump, liquid is exactly so continuously from liquid pool, be pumped up and continuously from discharge tube, flow out.
Submersible pump unit is by: water pump, submersible motor (comprising cable), conduit pipe and control switch four is most of forms.Submersible pump is single-suction multilevel vertical centrifugal pump; Submersible motor is airtight water-filling wet type, vertical three-phase squirrel-cage induction motor, and motor is connected by pawl formula or singly-bound cartridge type coupling with water pump; The three core cable of different size is equipped with; Starting equipment is air-break switch and the self-coupling decompression air-operated apparatus of different capacitance grade, and the steel pipe that conduit pipe is different-diameter is made, and adopts flange to connect, and high-lift electric pump adopts gate valve to control.
Because submersible pump working environment is below the water surface, but in some particular surroundings, do not get rid of the possibility that water pump emerges, at this time due to the reason of the outer machinery of environment own, pump body temperature may significantly raise, now just cooling system need to have been used, and water is good cooling medium, so cooling preferred water-cooling pattern of submersible pump, although submersible pump water outlet has higher hydraulic pressure, meet the required hydraulic pressure of cooling water completely, also there is no at present simple in structure can the using higher hydraulic pressure and can not cause the water-saving valve of too large impact to hydraulic pressure of a kind of submersible pump cooling system special use.
Model utility content
The utility model, just for above technical problem, provides simple in structure can the using higher hydraulic pressure and can not cause the water-saving valve of too large impact to hydraulic pressure of a kind of submersible pump cooling system special use.
The utility model is achieved through the following technical solutions.
A water-saving valve, comprises valve body, feed-water end, waterexit end, water intake, water outlet, it is characterized in that valve body one side arranges feed-water end, opposite side sets out water end (W.E.), and water intake is positioned at feed-water end inner side, and feed-water end arranges internal thread, water outlet is positioned at inner side, waterexit end, and waterexit end arranges outside thread.Water intake internal diameter is much larger than water outlet internal diameter.
Because water intake internal diameter described in the utility model is much larger than water outlet internal diameter, when current flow into intake pipe from water intake, the current by water-saving valve can slow down, thereby can be used to do water-cooled water source.
This water-saving valve is simple in structure, easy to use, safe and reliable.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model waterexit end one side structure schematic diagram, and Fig. 2 is the utility model feed-water end one side structure schematic diagram, and Fig. 3 is the utility model water intake schematic diagram, wherein:
1-valve body, 2-feed-water end, 3-waterexit end, 4-water intake, 5-water outlet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of water-saving valve, comprise valve body 1, feed-water end 2, waterexit end 3, water intake 4, water outlet 5, it is characterized in that valve body 1 one sides arrange feed-water end 2, opposite side sets out water end (W.E.) 3, water intake 4 is positioned at feed-water end 2 inner sides, feed-water end 2 arranges internal thread, and water outlet 5 is positioned at 3 inner sides, waterexit end, and waterexit end 3 arranges outside thread.Water intake 4 internal diameters are much larger than water outlet 5 internal diameters.
Because water intake 4 internal diameters described in the utility model are much larger than water outlet 5 internal diameters, when current flow into intake pipe from water intake, the current by water-saving valve can slow down, thereby can be used to do water-cooled water source.
This water-saving valve is simple in structure, easy to use, safe and reliable.
Claims (2)
1. a water-saving valve, comprises valve body, feed-water end, waterexit end, water intake, water outlet, it is characterized in that valve body one side arranges feed-water end, opposite side sets out water end (W.E.), and water intake is positioned at feed-water end inner side, and feed-water end arranges internal thread, water outlet is positioned at inner side, waterexit end, and waterexit end arranges outside thread.
2. a kind of water-saving valve according to claim 1, is characterized in that described water intake internal diameter is much larger than water outlet internal diameter.
