Abstract
The utility model discloses an anti-siphon water-saving valve, which comprises a body, wherein the body comprises a straight cylinder section, a first O-shaped ring is arranged outside the straight cylinder section, a limiting disc body convenient for being scratched out by bare hands is arranged at the water inlet end of the straight cylinder section, and the limiting disc body and the straight cylinder section are integrally formed; a clamping cylinder is arranged in a central hole of the straight cylinder section, an anti-siphon valve sheet is fixed in the clamping cylinder, and water inlet holes are uniformly distributed on the periphery of the clamping cylinder; the clamping cylinder is sleeved with a second O-shaped ring, and the water inlet hole is located on the inner side of the second O-shaped ring. The utility model discloses a water pressure makes the form control flow of intaking in O type circle deformation plugged hole, and water pressure is big more, and O type circle deformation is big more, and the flow of intaking just is little to reach the effect of water conservation. When water flows, the anti-siphon valve piece is opened along the deformation of water flow direction, thereby forming a water inlet state, when water is cut off, the water flowing backwards in the cavity can restore the anti-siphon valve piece to a normal state, thereby sealing all around, forming anti-siphon, and prolonging the service life greatly.
Description
Technical Field
The utility model relates to a valve body especially relates to an anti-siphon water-saving valve.
Background
At present, the anti-siphon water-saving valve on the market is of a straight cylinder type, is installed on a spray head in a plug-in installation mode, is difficult to take out during replacement, and needs to be detached by using other tools. When water enters, the spring water sealing shaft assembly in the middle is pressed down by using water pressure, and the water inlet flow is adjusted by using the water pressure, so that the water-saving effect is achieved. When the spring is fatigued or fails, the anti-siphon effect can be caused, and in severe cases, water can not enter or abnormal sound can be caused. Therefore, the development of an anti-siphon water-saving valve becomes a problem to be solved urgently by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model provides an anti-siphon water-saving valve for solving the defects.
The above object of the present invention is achieved by the following technical solutions: the utility model provides an anti-siphon water-saving valve, includes the body, the body includes the straight section of thick bamboo section, and the straight section of thick bamboo section outside is equipped with first O type circle, its characterized in that: a limiting disc body convenient for being pulled out by hands is arranged at the water inlet end of the straight cylinder section, and the limiting disc body and the straight cylinder section are integrally formed; a clamping cylinder is arranged in a central hole of the straight cylinder section, an anti-siphon valve sheet is fixed in the clamping cylinder, and water inlet holes are uniformly distributed on the periphery of the clamping cylinder; the clamping cylinder is sleeved with a second O-shaped ring, and the water inlet hole is located on the inner side of the second O-shaped ring.
Furthermore, the anti-siphon valve piece comprises a horn-mouth-shaped valve piece and a fixing plug pin, the horn-mouth-shaped valve piece and the fixing plug pin are integrally formed, and the fixing plug pin is provided with a reverse buckling chuck and is inserted into the clamping cylinder for fixing.
Compared with the prior art, the utility model the advantage be:
1. the water inflow rate is controlled in the mode that the O-shaped ring deforms to block the hole through the water pressure, the larger the water pressure is, the larger the O-shaped ring deforms, the smaller the water inflow rate is, and therefore the water saving effect is achieved.
2. When water flows, the anti-siphon valve piece is opened along the deformation of water flow direction to form the state of intaking, when cutting off the water supply, the water of intracavity refluence can resume normal state to the anti-siphon valve piece, thereby will seal all around, form anti-siphon (waterproof refluence), because the water of intaking all controls through water, there is not fatigue state, life promotes greatly.

Fig. 2 is a schematic side view of the present invention.
Fig. 3 is a cross-sectional view taken at a-a in fig. 2.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the anti-siphon water-saving valve comprises a body 1, wherein the body 1 comprises a straight cylinder section 1-1, a first O-shaped ring 2 is arranged on the outer side of the straight cylinder section 1-1, a limiting disc body 1-2 convenient for being pulled out by bare hands is arranged at the water inlet end of the straight cylinder section 1-1, and the limiting disc body 1-2 and the straight cylinder section 1-1 are integrally formed; a clamping cylinder 1-4 is arranged in a central hole 1-3 of the straight cylinder section 1-1, an anti-siphon valve piece 3 is fixed in the clamping cylinder 1-4, and water inlet holes 1-5 are uniformly distributed around the clamping cylinder 1-4; the clamping cylinder 1-4 is sleeved with a second O-shaped ring 4, and the water inlet hole 1-5 is positioned on the inner side of the second O-shaped ring 4.
Further, the anti-siphon valve piece 3 comprises a horn-shaped valve piece 3-1 and a fixing plug pin 3-2, the horn-shaped valve piece 3-1 and the fixing plug pin 3-2 are integrally formed, and the fixing plug pin 3-2 is provided with an inverted clamping head 3-3 and is inserted into the clamping cylinder 1-4 to be fixed.
When water flows, the water inflow is controlled in the mode that the second O-shaped ring 4 is deformed to block the hole through water pressure, the larger the water pressure is, the larger the deformation of the second O-shaped ring 4 is, the smaller the water inflow is, and therefore the water saving effect is achieved.
When leading to water, anti-siphon valve piece 3 is opened along water flow direction deformation to form the state of intaking, when cutting off the water supply, the water of intracavity refluence can resume normal condition to anti-siphon valve piece 3, thereby will seal all around, form anti-siphon (waterproof refluence), because the water of intaking all controls through water, there is not fatigue state, life promotes greatly.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
