Abstract
The utility model relates to a constant-flow water-saving valve, which can automatically regulate water out pressure and water out flow according to water supply pressure. The utility model comprises a valve core, a valve seat, a spring and a baffle plate, wherein the valve core and the valve seat are sheathed, and the spring and a position-limit mechanism are arranged between the valve core and the valve seat along an axial direction; the valve core can slide within a range limited by the position-limit mechanism; a flow regulating channel is formed between the valve core and the valve seat. When water in pressure is raised, the valve core is downward slid and the flow area of the flow regulating channel becomes small. When the water pressure decreased, the valve core is upward slid, the flow area of the flow regulating channel becomes big. Consequently, the automatic regulation of water supply flow, pressure and flow speed can be realized, optimal flow is provided for the water use and the water is effectively saved.
Description
It is dividing an application of 200520003919.2 utility application that the utility model name that to be the claimant propose on January 25th, 2005 is called " automatic water-saving device ", application number.
Technical field the utility model relates to a kind of water saving equipment, is specifically related to a kind of automatic flow rate adjusting device that can adjust water flow according to pressure of supply water automatically.
In the background technique prior art, the automatic flow rate adjusting device that can retrieve is that the Korean invents " running water output regulator ", this device has been applied for patent of invention and utility model patent in China, utility model patent notice of authorization CN2542897Y.Running water output regulator is converted into pressure, the moderate current of flow by the tap water that pressure is higher, reduces water consumption under the prerequisite that guarantees washing effect, has good water-saving result.But there is following defective in this device: 1, under the most frequently used DN15 caliber condition, the connecting part of spool flange and adjusting pin forms thin neck, and fatigue fracture takes place this thin neck easily; 2, the spool guide surface is short and have the shape that overhangs and regulate pin, and guidance quality, poor stability cause guide surface scratch, wearing and tearing easily, influences product working life; 3, regulate pin easily wearing and tearing and wearing and tearing cause the minimum current area of device to increase, thereby reduce water-saving result high hydraulic pressure under, shortening product working life; 4, the compression area of spool Parallel to the flow direction when the extreme higher position leaves the compression area of this position less than it, when reaching certain value, spool, hydraulic pressure produces when sliding off the extreme higher position downwards, compression area increases suddenly and causes spring moment surrender, spool sharply to glide, regulate pin and the water outlet hole wall bumps, quickens to regulate the wearing and tearing of pin, causes the water flow instability simultaneously, makes troubles to water.
The summary of the invention the purpose of this utility model provides a kind of constant current water-saving valve, this constant current water-saving valve can not only adjust water flow automatically according to pressure of supply water, promptly optimal stabilizing water quantity is provided, under the prerequisite that guarantees washing effect, reduces water consumption, realizes water saving for water automatically, and adjustment process is steady, water flow stable, valve core structure advantages of simple, guidance quality are good, long product lifecycle.
The purpose of this utility model is achieved in that the constant current water-saving valve comprises spool, valve seat, spring, baffle plate, and described valve seat is a cylindrical shell, and lower end and baffle plate are fixed; Spool is a cylindrical body, on its cylndrical surface tank is arranged; Valve core housing is combined in the valve seat and can slides in the position-limit mechanism restricted portion; Effect has spring between spool and the baffle plate; Tank on the spool and valve seat end face or boss form the Flow-rate adjustment passage.
Tank on the described spool cylndrical surface has at least one section cross section to become big from top to bottom gradually.
Tank on the described spool cylndrical surface does not run through the upper end of spool.
Have on the described valve seat locating flange that is suitable for embedded installation or directly with the screw thread of pipeline parts connection or flange, tooth, button.
Described position-limit mechanism comprises boss, back-up ring, position limit pin.
Described baffle plate comprises orifice plate, the gondola water faucet or the bubbler of spring-loaded mechanism is arranged.
The utility model has overcome the known technology adjustment process impact, water flow instability, and valve core structure is unreasonable, guidance quality is poor, defectives such as product weak point in working life; Break foreign technology monopolization simultaneously, helped the sound development of China's water saving cause.
Description of drawings Fig. 1 is main sectional view of the utility model embodiment one.
Fig. 2 is main sectional view of the embodiment two.
Fig. 3 is embodiment one a scheme of installation.
Among the figure, 1, spool, 2, valve seat, 3, spring, 4, baffle plate, 5, pipe member, 6, the constant current water-saving valve, 7, the water outlet pipe fitting, 8, position limit pin.
Embodiment Figure 1 shows that embodiment one of the present utility model, and baffle plate 4 is fixed on the lower end of valve seat 2, is provided with spring 3 between spool 1 and the baffle plate 4.Spool 1 is the cylindrical body that symmetrical tank is arranged on the cylndrical surface, and it is big that the cross section of top tank becomes from top to bottom gradually, and the upper-end surface of this section variable cross section tank and valve seat 2 forms Flow-rate adjustment passage, the circulation area maximum of shown position Flow-rate adjustment passage; Hydraulic pressure raises, and spool moves down, and the flow area of tank diminishes; Hydraulic pressure reduces, spool return upwards under spring promotes, and the tank flow area increases gradually.
Shown in Figure 3 is the scheme of installation of present embodiment.When pressure of supply water was lower than setting value, spool was motionless, the circulation area maximum of constant current water-saving valve Flow-rate adjustment passage, and promptly the constant current water-saving valve does not produce throttling action, does not influence water under the low hydraulic pressure low-pressure water.Intake pressure reaches setting value, and water pressure promotes spool and moves down, and the circulation area of Flow-rate adjustment passage diminishes gradually, intake pressure is high more, and the downward displacement of spool is big more, and the area of Flow-rate adjustment passage is more little, when spool and baffle plate applying, the area minimum of Flow-rate adjustment passage.When pressure of supply water reduced, spring promoted to move on the spool, and the circulation area of Flow-rate adjustment passage becomes greatly gradually, is returned to state shown in Figure 1 at last.
The flow of fluid and pressure, circulation area are directly proportional, so the utility model can the water supply that pressure is higher be converted into the stationary flow that pressure, flow are fit to, and reduce water consumption under the prerequisite that guarantees washing effect, realize water saving.
Shown in Figure 2 is embodiment two, be fixed with position limit pin 8 on the valve seat 2, spool 1 is that cylindrical body, the damaged surface that the upper end is formed with flange has tank and tank not to run through flange, on the spool cylinder restraining groove is arranged, tank on the spool and the upper-end surface of valve seat formation Flow-rate adjustment passage.The circulation area maximum of shown position constant current water-saving valve Flow-rate adjustment passage.
The effect that spool top is provided with flange is to form certain back pressure between spool flange and valve seat end face, improves the force-bearing situation of position limit pin.
The mounting type of present embodiment, working procedure are with embodiment one.
