Embodiment
Refer to Fig. 1 to 4, high pressure water tubular type one-way valve of the present utility model comprises the first flange 11, second flange 12, valve body 2, spool 3, spring 4, gland 5 and fixed component.Spool 3 is placed in valve body 2, and valve body 2 is held between the first flange 11 and the second flange 12, and the first flange 11 is connected by fixed component with the second flange 12, and is clamped by valve body 2.
Particularly, spool 3 is the hat shape of one end open, and its inwall is provided with a collar flange, and spool 3 is divided into opening end to the rear chamber of collar flange and collar flange to the front chamber of cap body by this collar flange.Spring 4 is placed in the rear chamber of spool 3, and an elasticity pressure surface of spring 4 and collar flange offset, and its another elasticity pressure surface stretches out the opening of spool 3.The sidewall of spool 3 front chamber is provided with multiple through hole.Valve body 2 is the tubulose of front end and back end opening.Spool 3 is placed in the inner chamber of valve body 2, and the opening end of spool 3 is towards the rear end of valve body 2, and the cap body of spool 3 is against the front opening place of valve body 2.Be provided with a treatment hole in the middle part of gland 5, its sealing covers the open rearward end of valve body 2, and is embedded in valve body 2, and the elasticity pressure surface that stretches out of the spring 4 in spool 3 and gland 5 offset, and the treatment hole diameter of gland 5 is less than the internal diameter of the elasticity pressure surface of spring 4.The external diameter of the rear chamber of spool 3 is slightly smaller than the internal diameter of valve body 2, leaves space between the front chamber of spool 3 and valve body 2.
First flange 11 is identical with the second flange 12 structure, is plate-like, and one plate face projection is round table-like, its another plate face indent, and matches with the end face of valve body 2.First flange 11 inner concave connects and is communicated with mating with the rear end of valve body 2, and the inner concave of the second flange 12 mates with the front end of valve body 2 and connects and be communicated with.The crowning of the first flange 11 welds with the mouth of pipe of pressure duct and is communicated with, and the crowning of the second flange 12 welds with low pressure line and is communicated with.
Described fixed component is multiple screw rod 61, spring pad 62 and nut 63.After the two ends of each screw rod 61 run through the bolt hole of the first flange 11 and the bolt hole of the second flange 12 respectively, after sheathed spring pad 62, screwed by nut 63 and first flange 11 and the second flange 12 are fixed.
Above-mentioned said, the front opening place that the cap body of spool 3 is against valve body 2 refers to, the external diameter of the cap body of spool 3 is greater than the internal diameter of the front opening of valve body 2.
Above-mentioned said, the open rearward end that gland 5 sealing covers valve body 2 refers to, gland 5 connects with the open rearward end turn-knob of valve body 2, and on gland 5 outer is overlapped seal ring 7.
Due to, the elastic force of spring 4, under normality, the cap body of spool 3 is against the front opening place of valve body 2.When dephosphorization injection valve cuts out without high-pressure water pressure, water on low pressure line promotes spool 3 and Compress Spring 4, form path, low-pressure water enters the space between spool 3 front chamber and valve body 2, and by after the front chamber of the through hole on spool 3 sidewall, spool 3, rear chamber, the treatment hole through overpressure cap 5 enters pressure duct.When dephosphorization injection valve is opened, the water of pressure duct enters spool 3 by treatment hole, pours into the cap body of spool 3, extension spring 4, and the cap body of spool 3 is against the front opening place of valve body 2, cuts off higher than pipeline and low pressure line.
Compared with prior art, high pressure water tubular type one-way valve structures of the present utility model is ingenious, and the pressure that can bear can reach 42Mpa, and the flow passed through reaches 600m
3/ h, pre-water-filling cracking pressure is little, in use low to water quality requirement, failure rate is low.And the utility model can be installed in dephosphorization system preliminary filling water lines, also can be installed on high-pressure water pump outlet and prevent high pressure water anti-channeling in pump, applicability is wide.
The utility model is not limited to above-mentioned mode of execution, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these change and modification.
