Abstract

The utility model relates to a valve, in particular to a rotary open-close type core-floating valve, which comprises a triple valve body, a floating valve core, a valve stem, a valve cap, a sealing ring and a valve stem control device. With full utilization of elastic feature of the plastics, a vertical claw is adopted to replace the cylinder at the upper part of the handle seat and a circular bead is used for limiting and locking, so as to lower manufacturing accuracy, reduce fittings and materials, simplify assembly process, cut down manufacturing cost and improve the stability of product quality. In addition, because a threaded sudden dropping structure and a spring are adopted, the valve can track the retracing position automatically when the water volume is quite small, so as to fasten up the water tap up, solve water-leakage problem for the water tap is not fastened up artificially and also resolve the water-leakage problem of the floating valve core type water tap due to mild wear of the valve core sealing ring.

Description

A kind of water drop proof tap

[technical field]

The utility model relates to valve.

[background technique]

Application number is that 00130747.9 patent application case has been announced a kind of rotary opening and closing formula floating plug stop valve, form by valve body, spool, valve rod, bonnet, Sealing and valve rod control gear, though solved water hammer, control water-outlet quantity easily, but its taper knob is whole tubular, consumptive material is many, lack flexibility, the dismounting difficulty, too big with the socket area of handle, accuracy of manufacturing is had relatively high expectations; And the valve rod control gear will come spacing by retainer ring, and accessory is many, and screw thread is many, has both increased packaging technology, improves manufacture cost, reduces the stability of quality of product again.In addition, existing water tap all can not solve and prevent that the problem, particularly people of dripping are the problem of dripping.

[summary of the invention]

The purpose of this utility model provides that a kind of accuracy of manufacturing is less demanding, and consumptive material is few, and accessory is few, and screw thread is few, and is simple for assembly process, low cost of manufacture, the rotary opening and closing formula valve with float valve core that constant product quality is high; Another purpose of the present utility model provides a kind of water drop proof tap.

The purpose of this utility model can realize by following proposal: a kind of rotary opening and closing formula valve with float valve core is made of three way valve, floating plug, valve rod, bonnet, seal ring and valve rod control gear; Valve stem packing ring, bonnet and La Gai after heat clinkering are passed in valve rod upper end, by snap-in buckle closure with its with draw cover latch to fix; Bar controlling is made up of the handle that draws lid, handle set and be enclosed within on the handle set; The handle set epimere has the perpendicular pawl of having of two symmetries of inside lobe, and hypomere is a tubular, and there is the outstanding shoulder of a circle inwall lower end, by the outstanding shoulder limitation locking on the bonnet outer wall; Two spiral chutes are arranged on the outer wall that draws lid of handle set inner chamber; Two lobes of symmetry are stuck in two spiral chutes on the handle set inwall; Draw the inwall design of lid that at least two uniform guiding grooves are arranged, corresponding with at least two uniform guiding ribs on the bonnet.When the taper knob left-right rotation, the lobe on the taper knob inwall can drive and draw lid to move up and down along the guiding rib on the bonnet, thereby drives the valve rod opening/shutting valve.

Make improvements slightly on the basis of aforesaid rotary opening and closing formula valve with float valve core, promptly obtain water drop proof tap: overlap upper spring on the valve rod, spiral chute upper wall end changes structure into.The initial position of falling screw thread suddenly is respectively 70 °-90 ° and 250 °-270 °.When closing water tap, when two lobes of symmetry on the handle set inwall rotate to when falling the screw thread place suddenly, under the effect of spring force, lobe can rise to the top rapidly, draws lid and valve rod to be about to water tap under rapid and fastens.

The utility model is owing to made full use of the resilient characteristic of plastics, and the handle set epimere replaces cylinder with perpendicular pawl, comes limitation locking with shoulder, has reduced accuracy of manufacturing, reduces accessory and material, and simplified assembling process reduces manufacture cost, the stability of improving the quality of products.In addition, owing to adopted screw thread to fall structure and spring suddenly, when the water yield is very little, can fasten water tap from the motion tracking return, solve the not tight water tap that causes in the artificial pass problem of dripping, also solved the problem that floating plug formula water tap has mild wear to leak because of valve core seal ring.

[embodiment]

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a longitudinal section of the present utility model tectonic maps.

Fig. 2 is the unfolded drawing of drawing cover outer wall.

Among the figure, 1. water nozzle 2. filter screens 3. valve bodies 4. valve seals 5. spools 6. valve core seal rings 7. valves emit 8. handle sets, 9. valve rods, 10. handles, 11. buckle closures, 12. valve stem packing rings 13. to draw to cover 14. springs

Shown in Figure 1 is a kind of rotary opening and closing formula valve with float valve core, by triple-valve body (3), float trap Core (5), valve rod (9), bonnet (7), sealing ring and valve rod control device consist of; On the valve rod (9) End passes valve stem packing ring (12), bonnet (7) He Lagai (13) after heat clinkering, by snap-in buckle closure (11) with its with draw lid (13) buckle to fix; Bar controlling is by drawing lid (13), handle set (8) Form with the handle (10) that is enclosed within on the handle set; The epimere of handle set (8) have two symmetries with The perpendicular pawl of inside lobe, hypomere are tubular, and there is the outstanding shoulder of a circle inwall lower end, by bonnet (7) Outstanding shoulder limitation locking on the outer wall; The outer wall that draws lid (13) at handle set (8) inner chamber has Article two, helicla flute; Two symmetrical on handle set (8) inwall lobes are stuck in two helicla flutes; Draw the inwall of lid (13) to be designed with at least two uniform gathering sills, with at least two on the bonnet (7) The uniform guiding rib of bar is corresponding.

In order to gain in strength, the epimere of handle set (8) can be established the perpendicular pawl of four symmetries in addition; All right Can be inserted in the groove of the perpendicular pawl of handle set (8) epimere the inwall setting of handle (10).

Make improvements slightly on the basis of aforesaid rotary opening and closing formula valve with float valve core aforesaid, promptly obtain water drop proof tap: valve rod (9) is gone up cover upper spring (14), draw spiral chute upper wall end on lid (13) outer wall to change screw thread into and fall structure suddenly, the initial position of falling screw thread suddenly is respectively 80 ° and 260 °.
