The utility model is composed of a valve core, a valve seat, a spring and a blocking plate, wherein the valve seat is a cylindrical shell, a water outlet hole or a slot is formed on the wall of the valve seat, and the lower end of the valve seat is fixed with the blocking plate; a hollow member with a water flow channel is formed in the valve core; the valve core and the valve seat are sheathed and can oppositely slide; the spring is acted between the valve core and the blocking plate; a hole or a notch on the wall of the valve core, or the end surface of the valve core forms a flow regulating channel with the water outlet hole or the slot on the wall of the valve seat. The utility model can automatically convert water supply with high pressure into stationary flow which is suitable for use, and the water is effectively saved on the precondition of ensuring the washing effect.
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.
The summary of the invention the purpose of this utility model provides a kind of motor valve, and this motor valve can not only adjust water flow automatically, realize water saving according to pressure of supply water, and valve core structure is reasonable, guidance quality is good, long product lifecycle.
The purpose of this utility model is achieved in that motor valve comprises spool, valve seat, spring, baffle plate, and described valve seat is a cylindrical shell, is formed with osculum or groove on the wall, and lower end and baffle plate are fixed; Spool is the hollow member that inside is formed with flow channel; 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; Osculum on hole on the spool wall or breach or spool end and the valve seat wall or groove constitute the Flow-rate adjustment passage.
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 blind plate, orifice plate, the gondola water faucet or the bubbler of spring-loaded mechanism is arranged.
The utility model has overcome defectives such as the known technology valve core structure is unreasonable, guidance quality is poor, and product is short working life, and mounting type is single; 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 the A-A sectional drawing of Fig. 2.
Fig. 4 is main sectional view of the embodiment three.
Fig. 5 is main sectional view of the embodiment four.
Fig. 6 is embodiment one, two, three a scheme of installation.
Among the figure, 1, spool, 2, valve seat, 3, spring, 4, baffle plate, 5, pipe member, 6, motor valve, 7, the water outlet pipe fitting.
Embodiment Figure 1 shows that embodiment one of the present utility model, and the Flow-rate adjustment passage of present embodiment is formed by the osculum on adjustment hole on the spool wall and the valve seat wall.As shown in the figure, spool 1 is a cup-shaped member, and Qi Bishang is provided with adjustment hole, and the bottom is provided with the minimum stream metering-orifice, and cup end outer wall has spacing preiection; The cylindrical of valve seat 2 is divided into two sections that diameter does not wait, and there is the installing and locating flange wherein big section upper end, and osculum is arranged on the segment, and inner upper end has positive stop lug boss, and baffle plate 4 is fixed on the lower end of segment, and osculum is arranged on the baffle plate; The two ends of spring 3 act on respectively on spool and the baffle plate; But spool, the inside and outside cover of valve seat merge slide relative, and the osculum on adjustment hole on the spool wall and the valve seat wall constitutes the Flow-rate adjustment passage.
The motor valve of present embodiment adopts embedded installation, as shown in Figure 6.When pressure of supply water is lower than setting value, spool is motionless, current flow out through two-way: the one tunnel through the spool wall raise knothole, valve seat wall upper water-out orifice flow goes out, one the tunnel through minimum osculum on the spool and the outflow of the osculum on the baffle plate, this moment, motor valve was not worked, promptly low-pressure water is not produced throttling action, do not influence water under the low hydraulic pressure.Intake pressure reaches setting value, and water pressure promotes spool and moves down, and adjustment hole on the spool wall and the osculum on the valve seat stagger, and the area of Flow-rate adjustment passage reduces; 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 Flow-rate adjustment pathway closure, current can only flow out by the minimum osculum on spool; Pressure of supply water reduces, and spring promotes to move on the spool, and the osculum on the adjustment hole on the spool wall, the valve seat wall overlaps gradually, and the Flow-rate adjustment passage is opened and become big gradually, is returned to state shown in Figure 1 at last, at this moment Flow-rate adjustment passage maximum.
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.
Fig. 2, shown in Figure 3 be embodiment two, the Flow-rate adjustment passage of present embodiment is formed by the osculum on breach on the spool wall and the valve seat wall, between above-mentioned breach and the osculum minimum flow channel is arranged when spool lower end and baffle plate are fitted, baffle plate is a blind plate.The mounting type of present embodiment, working procedure are with embodiment one.
Shown in Figure 4 is embodiment three, and the Flow-rate adjustment passage of present embodiment is directly formed by the osculum on spool wall lower end surface and the valve seat wall, and all the other are with embodiment one.
Shown in Figure 5 is embodiment four, and the Flow-rate adjustment passage of present embodiment is formed by the upper-end surface of the hole on the spool wall with " recessed " shape baffle plate.As shown in the figure, screw thread and the spacing inward flange that connects with the first-class pipeline parts of the fire hose arranged at valve seat top, the groove of a ring-type is fixed and formed to the baffle plate of bottom and " recessed " tee section, the hole of this annular slot and baffle plate outer ring constitutes exhalant canal, and one group of aperture at baffle plate " recessed " end constitutes minimum osculum.Present embodiment is a kind of gondola water faucet or basket strainer that adjusts the water flow function automatically that have.
