Abstract
The utility model discloses a water flow-limiting valve, relating to a water flow-limiting device of the branch pipeline of the water supply system, which is composed of a spring (2) telescoping and sliding along the axial direction (water flow direction), a valve core (3), and a closing ring (4), which are arranged in a valve body (1). The utility model has the advantages of stable water limit, simple structure, convenient installation and operation, etc. People can reaches planned and rational allocation of the procreative and the domestic water, and reduces the waste of the water resources.
Description
The utility model relates to a kind of water flow restricting means of water supply system lateral.
The water flow restricting means of known water supply system lateral, normally shutoff valve or shunting orifice plate.Shutoff valve is installed in the pipeline and passes through the cross section with the positioning control current of regulating block; To be current by predetermined hole then be installed among the pipeline by the cross section shunting orifice plate.Because above-mentioned current restricting means is subjected to the influence of water supply system pressure, changes in flow rate is bigger, still the unbalanced phenomenon that feeds water can appear, be in the same water supply system, the water flow of some lateral surpasses normal need, and other lateral water flows are not enough even be zero and influence people's life and process water to some extent.
The purpose of this utility model provides a kind of water flow limiting valve of water flow within limit that can stably limit lateral.
For reaching this purpose, the utility model is achieved in that
(water (flow) direction) flexible spring and the spool that slides, back-up ring that is fixed in valve body of reaching vertically is set in valve body, and the spool top flat is greater than the endoporus of water intake end back-up ring; The spool post jamb has the current through hole.So, water enters in the valve inleting water chamber through back-up ring endoporus pushing spool, and the gap that cooperates with valve body throat of through hole on the spool post jamb and spool is to the waterexit end again.When the hydraulic pressure of limiting valve feed-water end raises or the hydraulic pressure of waterexit end when reducing, the spool Parallel to the flow direction segment distance that slides, the sectional area that the through hole on the spool post jamb stretches out valve body throat reduces; Otherwise when limiting valve feed-water end hydraulic pressure reduces or the hydraulic pressure of waterexit end when raising, spool is subjected to the effect of the spring segment distance that back slides, and the sectional area that the through hole on the spool post jamb stretches out valve body throat increases, and the variation of water flow is within the flow of limit.
The utlity model has the advantage such as stable, simple in structure, easy for installation of restricting water supply, can make people reach planned with reasonably distribute or use and produce or domestic water, reduce the waste of water resources.
Be described in further detail below in conjunction with accompanying drawing.
Be provided with the spool (3) that can reciprocatingly slide vertically in the valve body (1), spool (3) top flat that is with spring (2) is corresponding to the back-up ring (4) that is arranged on valve body (1) feed-water end.Valve body (1) throat has the shoulder hole that spring (2) and spool (3) can be set, and has limited the axial position of spring (2) toward water (flow) direction than the end face of aperture, has limited the axial position of spool (3) toward water (flow) direction than the end face of macropore.Back-up ring (4) that valve body (1) feed-water end is provided with and the length of valve body (1) throat than end face formation valve body (1) water-inlet cavity of macropore, have the current through hole on the post jamb of spool (3), the top flat of spool (3) is greater than the endoporus of back-up ring (4) and the bore of valve body (1) throat shoulder hole, and the length of spool (3) is greater than the length of valve body (1) water-inlet cavity.Spool (3) can be under the effect of variation in water pressure and spring (2), and telescopic slide in water-inlet cavity vertically is to change the sectional area of current through hole.
When industry is made, can make series product according to different water flow restriction amounts.The length of spool (3) should be greater than the length of valve body (1) water-inlet cavity; Valve body (1) throat should be less than the spring bore than the bore of aperture; Spool (3) post jamb external diameter is slightly less than the bore of valve body (1) throat than macropore, is state movingly; Spool (3) top flat should be greater than the endoporus of back-up ring (4) and valve body (1) the throat bore than macropore.During assembling, back-up ring (4) should be anchored on the feed-water end of valve body (1).The two ends of valve and feedwater lateral are connected to general be threaded or flange plate is connected.The used material of limiting valve with the metallic material, nonmetallic material or the composite material that meet feedwater piping and require all can, be good with Cuprum alloy, stainless steel especially.
Claims (4)
1, a kind of water flow limiting valve of being made up of valve body, current limliting piece is characterized in that being provided with the spool (3) that can reciprocatingly slide vertically in the valve body (1), and spool (3) top flat that is with spring (2) is corresponding to the back-up ring (4) that is arranged on valve body (1) feed-water end.
2, water flow limiting valve according to claim 1 is characterized in that valve body (1) throat has the shoulder hole that spool (3) and spring (2) can be set.
3, limiting valve according to claim 1 and 2 is characterized in that spool (3) top flat is greater than the endoporus of back-up ring (4) and the bore of valve body (1) throat shoulder hole.
4, water flow limiting valve according to claim 1 is characterized in that the length of the length of spool (3) greater than valve body (1) water-inlet cavity.
