Abstract
The utility model relates to a liquid draining valve, which is characterized in that a valve base provided with a conical valve port and a valve cap provided with a drainage tube are provided; the valve base and the valve cap compose a valve cavity by screw thread; the valve cavity is provided with a valve core which is formed by the method that a conical valve plug is integrally connected with a cylinder with transversal through holes; when the valve cap is screwed down, the valve plug of the valve core closes the valve port of the valve base to stop the liquid; when the valve cap is screwed off, a clearance between the valve plug of the valve core and the valve port is formed; the liquid passes through the clearance and enters the cylinder of the valve core through transversal through holes of the cylinder of the valve core, and then the liquid is drained out from the drainage tube of the valve cap. The draining valve has simple structure, low cost, safety and reliability.
Description
The utility model relates to a kind of liquid emission valve.
Liquid emission valve is commonly called as tap.At present, tap is made up of parts such as valve casing, valve seat, valve core, hexagonal locking nut, handle, metal washer and rubber seal.Because its part is many, so this tap structure is complicated, manufacture cost is higher; Simultaneously because it uses seal ring that following deficiency is arranged: after service time was long, leading seal ring can ageing failure, will produce serious consequence if run into the unexpected damage of leading seal ring when discharging toxic liquid or flammable and combustible liquids.
The purpose of this utility model is to provide a kind of simple in structure, safe and reliable new liquid escape cock to replace present liquid emission valve.
Technical solution of the present utility model is to adopt a valve seat and the bonnet with liquid-discharging tube and assembling screw thread that is fused by liquid inlet pipe with taper valve port and cylinder with assembling screw thread and constitute, described valve seat and bonnet by its screw thread in conjunction with constituting a valve pocket; Cylinder by taper valve plug and band cross through hole is set in described valve pocket fuses and the valve core that constitutes, the taper valve plug of described valve core is facing to described valve seat taper valve port; The taper valve plug blocks the taper valve port to stop the flow of liquid mistake when tightening bonnet, produce the gap between taper valve plug and the taper valve port when unscrewing bonnet, liquid is entered in the valve core cylinder by valve core cylinder cross through hole after by this gap, discharges by flowing to the bonnet liquid-discharging tube in the valve core cylinder thereafter.The size of regulating gap between the valve plug of valve core and the valve seat valve port by the degree of tightness of regulating valve bonnet is with the purpose of the flow that reaches controlling liquid.
Brief description is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of valve seat described in the utility model;
Fig. 3 is the plan view of bonnet described in the utility model;
Fig. 4 is the plan view of valve core described in the utility model;
Fig. 5 is the left view of valve core described in the utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
Referring to Fig. 1, the utility model comprises that a valve seat (9) that is fused by liquid inlet pipe with taper valve port (7) (8) and cylinder (5) with assembling screw thread (12) and constitute, bonnet (1) with liquid-discharging tube (19) and assembling screw thread (13), one are fused by taper valve plug (11) and the cylinder (17) that has cross through hole (15) and the valve core (3) that constitutes; Described valve seat (9) and bonnet (1) by its screw thread (12) and (13) in conjunction with constituting a valve pocket, the taper valve port (7) that valve core (3) is among the described valve pocket, its taper valve plug (11) faces toward valve plug; Valve plug (11) and valve port (7) can not flow through for drive fit makes liquid when tightening bonnet (1), produce the gap between valve plug (11) and the valve port (7) when unscrewing bonnet (1) and make the flow of liquid mistake.For conveniently tightening or unscrewing bonnet (1), bonnet outside symmetry connects two handles (14).Referring to Fig. 2, valve seat described in the utility model (9) is fused by a liquid inlet pipe (8) and a cylinder (5) and constitutes, and liquid inlet pipe (8) is that bend pipe, its right-hand member with 90 ° of bendings has screw thread (10), its underpart of using in order to the connection fluid pipeline that a taper valve port (7) that flows through in order to controlling liquid is arranged; The cone-apex angle α of taper valve port (7) is 15 °～150 °, and the size of valve port cone-apex angle has a significant impact fluid flow, and the best cone-apex angle α of taper valve port (7) is 60 °～120 °.For guaranteeing no leakage, the conical surface roughness of taper valve port (7) to be had relatively high expectations, its roughness should be at least
Left-handed assembling screw thread (12), its inboard place near taper valve port (7) are arranged is an annular recess (6) to side surface outside the cylinder (5).Referring to Fig. 1, the effect of groove (6) is to be convenient to the cross through hole (15) that liquid enters valve core (3).Be free to slide in cylinder (5) for ease of valve core (3), the side surface roughness should be at least within the cylinder (5)
, be Spielpassung between valve core (3) and the cylinder (5).Referring to Fig. 3, bonnet described in the utility model (1) is fused by cylinder (4) and funnel (2) and constitutes.Side has two symmetrically arranged screw (20), its inboards in order to assembling handle (14) that the left-handed assembling screw thread (13) that is complementary with valve seat assembling screw thread (12) is arranged outside the cylinder (4).Referring to Fig. 4 and Fig. 5, that be complementary and cylinder (17) that have cross through hole (15) fuses and constitutes valve core described in the utility model (3) by the taper valve plug (11) that is complementary with valve seat taper valve port (7) with valve seat cylinder (5).The conical surface roughness of valve plug (11) and cone-apex angle should be with the taper valve port (7) of valve seat identical, directly should mate within footpath and the valve seat cylinder (5) outside the cylinder (17), its outer surface roughness should be identical with valve seat cylinder (5) inner surface roughness.The chamfering that the end of cylinder (17) has funnel (2) conical surface with bonnet to be complementary is beneficial to valve core (3) and locatees in the valve pocket that valve seat and bonnet constitute; The end of cylinder (17) has a vertical horizontal translot (18) by axis among the valve core (3) to let out from the threaded connection place of bonnet and valve seat with the assurance liquid that can not.Enter among the cylinder (17) of valve core (3) by the cross through hole (15) of valve core (3) for ease of liquid, 60 ° reaming is carried out in the aperture of described cross through hole (15).
Brief description mechanism of the present utility model.Referring to Fig. 1, bonnet (1) is tightened at ordinary times, and liquid enters valve seat liquid inlet pipe (8) back because the taper valve plug (11) of valve core (3) blocks valve seat taper valve port (7) by fluid pipeline, and liquid can not pass through valve port (7); When needing discharge liquid, unscrew bonnet (1), at this moment produce the gap between the taper valve plug (11) of valve core and the valve port (7), the size in this gap depends on the tightness of bonnet (1), liquid arrives annular groove (6) by this gap, thereafter entered the cylinder bore (16) of valve core (3) by valve core cross through hole (15), the liquid that enters cylinder bore (16) flows out by the liquid-discharging tube (19) of bonnet (1).
Simple in structure, the low cost of manufacture of the utility model is not simultaneously owing to holding flimsy sealing ring, so its safe and reliable, long service life.
