Description
Technical field
The utility model relates to water tap, especially a kind of high-pressure buffer device of water tap.
Background technique
The structure of water tap generally comprises turnover water pipe, valve body, spool, handle, and we control switch and the water-outlet quantity of spool indirectly by the unlatching of control handle.Under non-working condition, handle is in closed condition, and the spool now in water tap closes, and current are terminated in valve body by spool; And in use, spool moment converts unlatching to by closed, the current be cut off in valve body can cause impacting with high pressure to spool instantaneously under hydraulic pressure effect, and Long-Time Service then causes the shortening in spool life-span, causes the seepage of water tap.
In addition, once water tap generation seepage, we usually need to close the total threshold switch of domestic water and could maintain water tap, and this can impact the normal water supply of other relevant devices, causes inconvenience in life.
Model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of high-pressure buffer device of water tap.
The utility model solves the technological scheme that its technical problem adopts:
A kind of high-pressure buffer device of water tap, it comprises the valve body and spool that are interconnected, buffer volume is provided with between the water inlet of described valve body and described spool, buffering decompressing unit is provided with in described buffer volume, described buffering decompressing unit comprises the chock plug being tightened in described buffer volume port and the adjusting screw rod be threadedly connected in chock plug, described chock plug is set with buffer air bag, and described adjusting screw rod is supported in above described buffer air bag bottom surface, and described buffer air bag is just to water (flow) direction.
Described buffer air bag is U-shaped solid of rotation, and bottom indent forms boss, and described adjusting screw rod is supported in above boss.
Described buffer air bag arranged outside has train of dress to extend to bottom.
Described buffer air bag end face extends annular sealing surface, and described annular sealing surface is located between the limited step of described chock plug and described buffer volume.
Wear-resistant gasket is provided with between described annular sealing surface and described chock plug.
Described chock plug end face is provided with two instrument jacks.
Establish step hole in described chock plug, described adjusting screw rod is limited in described step hole.
The beneficial effects of the utility model are: by the buffering decompressing unit arranged between the water inlet and spool of valve body, carry out step-down buffering to current, reduce current to the direct impact force of spool, avoid because high pressure causes the lost of life of spool; And, by the ingehious design of adjusting screw rod, on the one hand when buffer air bag can be played a supporting role by during water impact, adjusting screw rod can also coordinate the sealing of buffer air bag realization to water channel on the other hand, conveniently the maintenance of faucet valve core is nursed, and the normal water supply of miscellaneous equipment can not be affected.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is decomposing schematic representation of the present utility model;
Fig. 2 is the partial sectional view of utility model works state;
Fig. 3 is the sectional view of buffer air bag;
Fig. 4 is the partial sectional view of another working state of the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of high-pressure buffer device of water tap, it comprises the valve body 1 and spool 4 that are interconnected, buffer volume 3 is provided with between the water inlet 11 of described valve body 1 and spool 4, buffering decompressing unit 2 is provided with in described buffer volume 3, described buffering decompressing unit 2 comprises the chock plug 21 being tightened in described buffer volume 3 port and the adjusting screw rod 22 be threadedly connected in chock plug 21, chock plug 21 is set with buffer air bag 23, adjusting screw rod 22 is supported in above buffer air bag 23 bottom surface, and described buffer air bag 23 is just to water (flow) direction.
When spool 4 is by the closed moment converting unlatching to; high-pressure water flow enters valve body 1 inner chamber by water inlet 11; flow to buffer air bag 23; low pressure water flow after buffering step-down flows into spool 4 again; the current avoiding instantaneous pressure directly flow to spool 4 and form impacting with high pressure; be conducive to protecting ceramic valve core, increase the service life.
With reference to Fig. 3, buffer air bag 23 is U-shaped solid of rotation, and bottom indent forms boss 231, and buffer air bag 23 arranged outside has train of dress 232 to extend to bottom; When current flow into the boss 231 of indent bottom buffer air bag 23 from water inlet 11, boss 231 pairs of high-pressure water flows rise and hinder hypotensive effect for the first time, are the first buffering suface herein; Then the V-type that current are formed through bottom indent again folds and carries out second time step-down, and this is the second buffering suface; Carry out third time step-down finally by train of dress 232, this is the 3rd buffering suface.By three rank buffering step-downs, reduce the pressure of current gradually, finally flow into spool 4.
The annular sealing surface 233 that buffer air bag 23 end face extends, annular sealing surface 233 is located between the limited step 31 of chock plug 21 and buffer volume 3, the installation being convenient to buffer air bag 23 is on the one hand fixed, buffer air bag 23 is prevented to be out of shape or displacement under high-pressure water flow, affect antihypertensive effect, annular sealing surface 233 also can play seal action on the other hand, fills up the gap of valve body 1 and chock plug 21.
Because buffer air bag 23 is elastic silica gel material, causing for avoiding friction damage losing efficacy, between annular sealing surface 233 and tightening nut 3, being also provided with wear-resistant gasket 6.
In the present embodiment, chock plug 21 end face is provided with two instrument jacks 211 for self-control spanner locating rotation; Establish step hole 211 in chock plug 21, adjusting screw rod 22 is limited in this step hole 211, and adjusting screw rod 22 can only be installed by the bottom of chock plug 21, loses when avoiding external.
Under conventional operational state, the boss 231 of buffer air bag 23 is in normal state, adjusting screw rod 22 is supported in above boss 231, buffer air bag 23 plays hypotensive effect with reference to shown in Fig. 4, when spool 4 needs to change or keep in repair, and can by the lifting of adjusting screw rod 22, make buffer air bag 23 that deformation occur, boss 231 moves to osculum 11 end face, thus plays seal action, and so we would not impact the water supply of miscellaneous equipment when maintaining spool 4.
