Abstract
The invention relates to an energy saving noise abatement check valve comprising a valve body, a valve stem, a valve clack, a spring and a liner; the center of the liner is provided with a through hole; a valve clack seal ring is arranged between the valve stem and the valve clack; the liner is fixedly connected with the valve body through bolts; two ends, close to end faces of the valve body, of the valve stem are respectively fixedly connected with a first guide copper sleeve and a second guide copper sleeve; one end of the first guide copper sleeve is arranged in the valve body, and the other end is arranged outside the valve body and provided with a guide copper sleeve stop ring; the center of an outer surface of the second guide copper sleeve is arranged in the through hole of the liner, and two ends of the second guide copper sleeve extend outside the through hole of the liner; one end, close to the valve body end face, of the second guide copper sleeve is provided with a guide copper sleeve stop ring; an inner wall of the valve body is fixedly connected with a protection plate. The energy saving noise abatement check valve can ensure an energy saving effect, can ensure a sealing property, and can be conveniently repaired when being broken.
Description
Technical field
The present invention relates to a kind of energy-saving damping safety check.
Background technique
Damping check valve refers to and relies on medium flowing itself and automatic open and close flap, is used for the valve preventing medium from flowing backwards, and its Main Function prevents medium refluence, prevents water pump and drive motor from reversing.Protection pipe network normally runs.Damping check valve mainly comprises valve body, guide sleeve, valve rod, flap, spring, lining, existing damping check valve, cast iron valve body targeting part wear resistant corrosion resistant is poor, valve rod runs a period of time post gap and increases on valve body guide sleeve, guidance quality reduces, noise increases, and energy-saving effect declines, and time serious, valve rod is stuck; Flap and valve rod are an entirety, once valve rod and flap perpendicularity are processed with deviation, cannot ensure sealing; Lining adopts with valve body and is threaded, once spring cannot be used by sludge blockage, when breaking down, if do not have professional tool just bad replacing, is not easy to maintenance, and the insufficient strength of existing valve body, easily damage.
Summary of the invention
The object of the invention is to solve cast iron valve body targeting part wear resistant corrosion resistant poor, after running a period of time, guidance quality reduces, the problem that energy-saving effect declines; If valve rod and flap perpendicularity are processed with deviation, the problem that sealing can reduce; The problem of keeping in repair is not easy to when breaking down.
The technical solution used in the present invention is: a kind of energy-saving damping safety check, comprise valve body, valve rod, flap, spring, lining, the central authorities of lining are provided with through hole, valve clack sealing ring is provided with between described valve rod and flap, described lining is fixedly connected with valve body bolt, described valve rod two ends are fixed with the first guide copper sleeve and the second guide copper sleeve respectively near valve body end, and one end of the first guide copper sleeve is positioned at valve body, the other end is provided with the guide copper sleeve back-up ring be positioned at outside valve body; Second guide copper sleeve outer surface central authorities are positioned at the through hole of lining, two ends are stretched out outside the through hole of lining, and described second guide copper sleeve is provided with guide copper sleeve back-up ring in one end of close valve body end, and described valve interior wall is fixed with protection apron.
The beneficial effect that the present invention adopts is: after have employed this structure, valve rod is provided with guide copper sleeve, improves wear resistance and corrosion resistance, guidance quality will being caused to reduce because using for a long time, ensure that energy-saving effect; Between valve rod and flap, be provided with valve clack sealing ring, because seal ring is flexible, valve rod and flap will cause sealing to reduce because of the deviation of processing, and ensure that sealing; The bolt only need pulling down lining when breaking down just can take out spring and flap, and does not need by professional tool, is convenient to maintenance; Protection apron strengthens body strength, extends working life.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Shown in figure: 1 valve body, 2 valve rods, 3 flaps, 4 springs, 5 linings, 6 valve clack sealing rings, 7 first guide copper sleeves, 8 second guide copper sleeves, 9 guide copper sleeve back-up rings, 10 bolts, 11, protection apron.
Embodiment
Below in conjunction with Fig. 1, the present invention is described further.
As shown in Figure 1, a kind of energy-saving damping safety check, comprise valve body 1, valve rod 2, flap 3, spring 4, lining 5, the central authorities of lining 5 are provided with through hole, valve clack sealing ring 6 is provided with between described valve rod 2 and flap 3, described lining 5 is fixedly connected with valve body 1 bolt 10, and it is outer and be provided with guide copper sleeve back-up ring 9 that described valve rod 2 two ends are fixed with the first guide copper sleeve 7 and the second guide copper sleeve 8, first guide copper sleeve 7 respectively one end near valve body 1 end is positioned at valve body 1, the other end is positioned at valve body 1; Second guide copper sleeve 8 outer surface central authorities are positioned at the through hole of lining 5, two ends are stretched out outside the through hole of lining 5, and described second guide copper sleeve 8 is provided with guide copper sleeve back-up ring 9 in one end of close valve body 1 end, and described valve body 1 inwall is fixed with protection apron 11.
After present invention employs said structure, valve rod is provided with guide copper sleeve, improves wear resistance and corrosion resistance, guidance quality will being caused to reduce because using for a long time, ensure that energy-saving effect; Between valve rod and flap, be provided with valve clack sealing ring, because seal ring is flexible, valve rod and flap will cause sealing to reduce because of the deviation of processing, and ensure that sealing; Lining is fixedly connected with valve body bolt, and the bolt only need pulling down lining when breaking down just can take out spring and flap, and does not need by professional tool, is convenient to maintenance; Protection apron strengthens body strength, extends working life.
