Abstract
The utility model relates to a pipe hoop type water saving device which is arranged on a water inlet pipeline of a valve and is controlled to be closed by means of the pressure difference of running water. The utility model is composed of a positioning sleeve, throttling disks, pressure springs, etc., wherein, the pressure springs are arranged between the two throttling disks or are arranged among the throttling disks and a positioning sheet. The maximum control quantity of water supply depends on the pressure of the pressure springs. When water pressure is too large, the utility model can automatically close a water supply passage. The utility model which can save water, can prevent accident overflow, can simultaneously control the water pressure of the water supply passage, and can improve water supply conditions for high floors has the advantages of convenient installation and good sealing performance.
Description
The utility model relates to a kind of water economizer that is installed on the valve inlet pipeline.Belong to the throttling components and parts.
When cutting off the water, people often open valve and forget again and shut, and indoor unmanned valve again can not automatic control during water supply, and overflow completely causes damage.In addition, water supply line designs by maximum water supply volume, and does not often need peak discharge at ordinary times, but people often get used to water tap is reached maximum, causes water waste.
Present existing water economizer, though can reach the purpose of water saving, water economizer need be contained in the inside of water tap water inlet, because the internal diameter of water tap water inlet is lack of standardization as Chinese patent 90223558.3 described water economizers, sealing between water economizer and the water tap is bad, leaks easily.
The purpose of this utility model provides a kind of water economizer of collar-shaped, can be contained in the outside of valve, and is easy for installation, and sealing better.
The purpose of this utility model is achieved in that water economizer is made up of positioning sleeve, dam dish, compression spring etc., it is characterized in that: the positioning sleeve of water economizer is inner to be the bucking ladder shape, two dishes that dam are oppositely arranged (perhaps the dish that dams is oppositely arranged with spacer), the dish that dams is provided with guide rod, and two dam between the dish or the setting pressure spring between dish and the spacer that dams.
Import and export in the positioning sleeve of water economizer has a ring groove, and jump ring is housed in the groove, works dish, the spacer effect of damming of locating.
The dam dish outside is the plane, and the inner central section position is round table-like, carves a groove on the round platform, and sealing ring is housed in the groove, is 120 ° or 180 ° vertically at the external diameter of round platform and is provided with guide rod.There is an outstanding garden platform or a cone spacer inner central section position, and its external diameter plays positioning pressure spring and shunting action less than the internal diameter of compression spring.
When hydraulic pressure was excessive, the pressure that the dish that dams is born forced length of spring compressed, causes throttling dish and positioning sleeve closure.When hydraulic pressure hour, the dish pressure that dams reduces, spring is opened automatically, the dish that dams separates with positioning sleeve, realizes the purpose of economizing on water.
The utility model is because of on the inlet pipeline that is installed in valve, and is easy for installation, and sealing better can be directly used in existing supply channel and existing valve (water tap) is used.Reach the purpose of water saving, anti-overflow, improvement water supply environment.
The present invention is further detailed explanation below in conjunction with specific embodiment:
Fig. 1 is the sectional drawing that the utility model adopts the water economizer of two dishes that dam;
Fig. 2 is the sectional drawing that the utility model adopts the water economizer of dam a dish and a spacer;
Fig. 3 is the elevation of the dish that dams of the utility model water economizer.
The utility model water economizer outward appearance is as pipe collar, and positioning sleeve 3 inside of water economizer are the bucking ladder shape, and import and export has an annular recess, and jump ring 2 is housed in the groove.Two dishes that dam 1 are oppositely arranged, and (perhaps the dish 1 that dams is oppositely arranged with spacer 7), the outer wing that dish 1 outer ring of damming is 120 ° or yi word pattern plays location and position-limiting action.The dish 1 inner central section position of damming is round table-like, carves a groove on the platform of garden, and sealing ring 6 is housed in the groove, fixes several guide rods 4 on the dish 1 that dams, and plays fixation pressure spring 5.When water economizer adopted two dishes 1 that dam to be oppositely arranged, compression spring 5 was contained in two and dams between the dish 1.When adopting the dish 1 that dams to be oppositely arranged with spacer 7, compression spring is contained in and dams between dish and the spacer.There is an outstanding garden platform or a cone spacer 7 inner central section positions, and its external diameter plays positioning pressure spring and shunting action less than the internal diameter of compression spring.There is screw thread at the import and export both ends of positioning sleeve, match with supply channel.The maximum limit flow that supplies water is controlled by the pressure of adjusting compression spring.When hydraulic pressure is excessive, the pressure that the dish that dams is born forces spring to shrink, cause dam dish and positioning sleeve closure, thereby prevent the accident of metalling run out when hydraulic pressure increases suddenly, also guaranteed the hydraulic pressure of supply channel, improve the building water supply condition, the effect of sealing ring is the gap sealing that makes the contact surface between dish and the positioning sleeve that dams, and anti-sealing flows through from the gap.Jump ring be used for locating another one dam the dish or spacer.Work as valve-off, eliminate the differential water pressures of the device both sides of intercepting water, compression spring is opened automatically, and the dish that dams is separated with positioning sleeve, reopens the water supply path.
The inlet pipeline specification with the institute mounted valve of selecting for use of water economizer is complementary.The material of water economizer can be selected nontoxic, rush-resisting material for use.
Water economizer adopts the effect of two dishes that dam just to be that water economizer two can use.Because of being installed in the pipeline outside, easy for installation, seal better again.Can be directly used on the existing supply channel, reach the purpose of water saving, anti-overflow, improvement water supply environment.
