Abstract
The utility model discloses an inelastic reset one-way valve which comprises a valve body (1) with an inlet/outlet and a steel ball (6), wherein an outlet joint (2), a backing ring (4), an outlet valve sleeve (5) and an inlet valve seat (7) are arranged in the valve body; the steel ball (6) is arranged on a taper hole at the upper end of the inlet valve seat (7) and is limited in a channel type cavity hole (9) between the outlet valve sleeve (5) and the inlet valve seat (7); and a pressure medium enters the outlet channel of the backing ring (4) through a radial inclined hole (8) formed on one side of the outlet valve sleeve (5). In the utility model, by adopting a non-spring one-way valve structure formed by the pressure medium entering the outlet channel through the radial inclined hole of the outlet valve sleeve, the reliability is high, the passing loss of the pressure medium is little, and the problem of fault generation caused by the failure or damage of the spring of the prior art is avoided. The inelastic reset one-way valve disclosed by the utility model is suitable for the medium-low pressure working environment as well as the ultrahigh-pressure working environment, and the failure parts are very convenient to maintain and replace.
Description
Technical field
The utility model relates to a kind of one-way valve that is applied to hydraulic transmission and control or Pneumatic Transmission and control.
Background technique
One-way valve is hydraulic transmission and the control valve commonly used of controlling perhaps Pneumatic Transmission and control, is used for realizing only allowing medium to flow to a direction, and does not allow reverse flow.The one-way valve that generally is used for middle low-pressure system all is the structure that prevents the medium reverse flow that adopts spring and steel ball (perhaps cone) to form usually.The deficiency of this structure is that pressure medium gets into from import, need overcome the resistance of spring, makes to import and export to communicate, and therefore the pressure loss is arranged; At work, spring is prone to lose efficacy, even is damaged, and will produce hydraulic system fault, poor reliability.
Summary of the invention
It is little that the task of the utility model provides a kind of pressure loss, and reliability is high, both has been applicable to the mesolow working environment, is applicable to the one-way valve of ultrahigh pressure working environment again.
The utility model solves the technological scheme that its technical problem adopted: a kind of non-resilient reset check valve; Comprise; A valve body 1 that is provided with import and export; Outlet connection 2, gasket ring 4, outlet valve pocket 5, import valve seat 7 are arranged in the valve body, be arranged on the steel ball 6 on the import valve seat 7 upper end taper holes, it is characterized in that; Described steel ball 6 is limited in the channel-style lumen pore 9 between outlet valve pocket 5 and the import valve seat 7, and pressure medium gets into gasket ring 4 outlet passages through the radially inclined hole 8 that is arranged on outlet valve pocket 5 one sides.
The utility model has following beneficial effect than existing technology:
The utility model adopts steel ball 6 to be limited in the channel-style lumen pore 9 between outlet valve pocket 5 and the import valve seat 7; The radially no spring non-return valve structure of inclined hole 8 entering outlet passages formations of outlet valve pocket is set; Not only reliability is high; Pressure medium is little through loss, and has avoided the existing technology spring failure or damaged the failure problems that produces.This mode of structure need not spring driving steel ball and resets, and steel ball automatically replies under action of gravity; Accomplish the break-make of one-way flow; Both be applicable to the mesolow working environment, and be applicable to the working environment of ultrahigh pressure again, the maintenance of inefficacy part and replacing are all very convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model one-way valve.
Among the figure: 1 valve body, 2 outlet connections, 3 combination seals, 4 gasket rings, 5 outlet valve pockets, 6 steel balls, 7 import valve seats, 8 inclined holes radially, 9 channel-style lumen pores, 10 step side openings, 11 central small hole, 12 taper hole passages.
Embodiment
Consult Fig. 1.The non-resilient reset check valve that the utility model proposes has a valve body 1 that is provided with import and export, and outlet connection 2, gasket ring 4, outlet valve pocket 5, import valve seat 7 are arranged in the valve body, is arranged on the steel ball 6 on the import valve seat 7 upper end taper holes.Steel ball 6 is arranged on the import valve seat 7 upper end taper holes.Taper hole that import valve seat 7 upper-end surfaces are provided with and steel ball sphere form linear sealing.Between outlet valve pocket 5 and the import valve seat 7 combination seal 3 is arranged, be used for the medium of leakproof one-way valve outlet end.Steel ball 6 is limited in the channel-style lumen pore 9 between outlet valve pocket 5 and the import valve seat 7.Be shaped on the axial taper hole passage 12 and step side opening 10 that is communicated with upper end gasket ring 4 on outlet valve pocket 5 cylndrical surface, central small hole 11 is communicated with upper end gasket ring 4 taper hole passages 12.Outlet valve pocket 5 is shaped on and forms the fluid passage, and the radially inclined hole 8 in continuous passage die cavity hole 9.Taper hole passage 12 continuous outlet connection 2 holes in the gasket ring 4 make MEDIA FLOW to channel B.Outlet connection 2 can connect through screw thread or flange arrangement with valve body 1.
After pressure medium got into from import A, pressure medium promoted steel ball 6 and moves upward, and fluid gets into gasket ring 4 outlet passages through the radially inclined hole 8 that is arranged on outlet valve pocket 5 one sides, gets into gasket ring 4 fluid passageway, gets at last in outlet connection 2 holes.
When import A did not have pressure medium, steel ball 6 automatically reset under action of gravity, formed sealing with import valve seat 7, and pressure medium can not reverse flow.
It is the superhigh pressure sealing structure that combination seal between combination seal and outlet valve pocket and the import valve seat is arranged between outlet connection and the last gasket ring.
Claims (4)
1. non-resilient reset check valve; Comprise that a valve body (1) that is provided with import and export has outlet connection (2), gasket ring (4), outlet valve pocket (5), import valve seat (7) in the valve body; Be arranged on the steel ball (6) on the taper hole of import valve seat (7) upper end; It is characterized in that described steel ball (6) is limited in the channel-style lumen pore (9) between outlet valve pocket (5) and the import valve seat (7), pressure medium gets into gasket ring (4) outlet passage through the radially inclined hole (8) that is arranged on outlet valve pocket (5) one sides.
