Abstract
The utility model relates to a back stop hose joint; the utility model is a component which has a back stop function and is used for connecting a hose with a water heating pipeline. A bush (2), an end cover (3), a valve core (5) and springs (4) are installed in a housing. The utility model has the advantages of favorable air tightness, small opening pressure and little possibility of leakage. The utility model is suitable for applying to a pipeline under the condition that water (air) pressure is less than 0.03MPa.
Description
The utility model belongs to the hot-water heating pipeline fittings.
Known hose coupling does not have the check function.Known pipeline check valve all has seepage in various degree, and cracking pressure is bigger, uses poor air-tightness on the pipeline of water (gas) pressure less than 0.03MPa.
The purpose of this invention is to provide a kind of check function that has, be used for the parts that flexible pipe is connected with the hot-water heating pipeline.And when on the pipeline of water (gas) pressure less than 0.03MPa, using, ne-leakage, cracking pressure is little.
The hose coupling that the utility model relates to adopts following structure to realize: an end of being known housing (1) by figure connects flexible pipe, and the other end has pipe thread and can be connected with pipeline.Lining (2), end cap (3), spool (5) and spring (4) are equipped with in the inside of housing (1).Wherein lining (2) adopts elastic material (as rubber) to manufacture.The round platform inlay busher (2) of end cap (3) inner end makes lining (2) fixing.The round bar of spool (5) is overlapping the circular hole that spring (4) inserts end cap (3) center.Under the effect of spring (4), the conical end of spool (5) contacts with the circular hole of lining (2) bottom, thereby plays the check seal action.When water (gas) pressure of the connection hose end of housing (1) during greater than the water that end cap (3) one ends are housed (gas) pressure, spool (5) is opened, water (gas) one-way flow.Because employing lining (2) connects together with end cap (3) and sleeve is the structure of valve seat, has improved the check tightness.Spool (5) is when closing, and the length of spring is almost free length, has therefore reduced cracking pressure.
The spheroid that spool (5) can adopt corrosion resistant material to manufacture replaces.
The utlity model has the check function, cracking pressure is little, ne-leakage.Be adapted at using on the pipeline of water (gas) pressure less than 0.03MPa.
When the utility model was used for the automatic water-adding system of solar water heater, the pipeline nominal diameter was 15mm, and the design water temperature is 90 ℃, and housing (1), end cap (3), spool (5) are manufactured with brass material.Lining (2) silica gel or neoprene are manufactured.It is the coiling of 0.3mm Stainless Steel Wire that spring (4) adopts diameter, and its external diameter is that 6mm, free length are that 10mm, pitch are 1.8mm.

Claims (2)
1. the check hose coupling is characterized in that lining (2), end cap (3), spool (5) and spring (4) are equipped with in the inside of housing (1).Lining (2) connects together with end cap (3), and sleeve is a valve seat.
2. check hose coupling according to claim 1 is characterized in that the spheroid that spool (5) can adopt corrosion resistant material to manufacture replaces.
