Problems solved by technology

With the improvement of people's living standards, some devices in the family need no-pressure or low-pressure water supply. In other public places, reducing the tap water pressure can save a lot of water resources, but the water valves we use now do not have a stable pressure-reducing function. , only acts as a switch

Embodiment Construction

[0009] For the decompression and slow flow water-saving valve, a valve core (3), a guide rod (4), a compression spring (5), a stop ring (2), a tail cover (6) and a valve body are installed in the valve body (1). (1) Sealed and fixed, the spool (3) is in the shape of a conical table, with several grooves on its side, the large end of the spool (3) faces the water inlet of the valve body (1), and the large end of the spool (3) is Bowl-shaped concave surface, the small end surface is fixedly connected with the guide rod (4), the compression spring (5) is sleeved on the guide rod (4), one end of the compression spring (5) is against the small end surface of the valve core (3), and the other end is against the tail The cover (6), the stop ring (2) is installed between the water inlet of the valve body (1) and the valve core (3), at the limit position of the movement of the valve core (3), there are several channels on the stop ring (2). Hole, the side wall of the valve body (1) inn...

Abstract

The present invention is one kid of valve and is superior to available water valves without presure reducing function. The valve of the present invention has increased valve core, guide rod, compressing spring, limiting ring and tail cover inside the valve body. The conic valve core has notch on the side, lrge end opposite to the water inlet and small end fixed to the guide rod; the compressing spring has one end pushing against the small end of the valve core and the other end pushing against the tail cover, the limitingring determines the limit position of the valve core; and the valve body has inner wall in the shape fitting the conic valve core. The present invention has simple and compact structure and water flow buffering and pressure reducing effects.

Description

Technical field [0001] The invention belongs to a valve, which relates to a decompression, slow flow and water saving device. Background technique [0002] Now the urban tap water supply system adopts mechanical pressurization, so when the tap water reaches each user, the pressure of the tap water will be different due to the location and time. Some places have high pressure, and some places have low pressure. With the improvement of people's living standards, some devices in the family need no-pressure or low-pressure water supply. In other public places, reducing the tap water pressure can save a lot of water resources, but the water valves we use now do not have a stable pressure-reducing function. , which only acts as a switch. Therefore, people are pressing for a kind of device, can stabilize tap water hydraulic pressure well. Contents of the invention [0003] The object of the present invention is to provide a pressure-reducing, slow-flow and water-saving valve wi...
