Abstract
The invention discloses a brand-new pressing type delay self-closing faucet. The technical problems that after an ordinary pressing type delay self-closing faucet is used for a long term, water closing is not tight, rapid bouncing occurs after pressing, and consequently the delay self-closing effect is lost are solved, and the service life of the faucet is greatly prolonged.
Description
Technical field
The present invention relates to a kind of water tap, particularly relate to a kind of push type time-delayed self-turning off tap.
Background technique
Public sanitary place, for water-saving object, often uses time-delayed self-turning off tap.Common push type time-delayed self-turning off tap structure is simple, low price, but it is shorter to there is working life, holds flimsy shortcoming.Common technical problem is: the water bolt that closes of push type time-delayed self-turning off tap is generally made up of rubber, and Long-Time Service easily weares and teares, and causes closing water imprecision, occurs leaking, seeping water phenomenon.And after closing the wearing and tearing of water bolt, because the friction factor closing water bolt and water tap cavity inner wall reduces, water tap resilience fast after pressing can be caused again, lose the function that water is closed in time delay.The present invention designs a kind of brand-new push type time-delayed self-turning off tap, solves above-mentioned technical problem, makes water tap have longer working life.
Summary of the invention
As shown in Figure 1, push type time-delayed self-turning off tap, comprises cavity 15, intake pipe 1, outlet pipe 2, pressure cap 7, returning spring 8, quality of rubber materials close water bolt 9, cross section is circular connecting rod 11.Cavity 15 is divided into water-inlet cavity 3 and water chamber 4.Intake pipe 1 is connected with water-inlet cavity 3, and outlet pipe 2 is connected with water chamber 4.Spilled water hole 5 and water inlet 6 is had between water-inlet cavity 3 and water chamber 4.Be enclosed within above cavity 15 outside pressure cap 7, between pressure cap 7 and cavity 15, be connected with returning spring 8.Connecting rod 11 longitudinally penetrates water chamber 4, connecting rod 11 upper end is connected with pressure cap 7, connecting rod 11 lower end with close water bolt 9 and be connected, close water bolt 9 and remain close contact with the madial wall of water chamber 4, and close water bolt 9 and can pump in water chamber 4, when pressure cap 7 does not press, close water bolt 9 and just in time block water inlet 6.The feature of this push type time-delayed self-turning off tap is: the threaded connecting rod cap 12 of appearance is processed in connecting rod 11 upper end, connecting rod cap 12 is connected with pressure cap 7 bolt, the top of connecting rod cap 12 has the screw edge of a knife, connecting rod 11 lower end is the connecting rod head 13 of reverse frustoconic, close in the middle of water bolt 9 and have reverse frustoconic groove 10, connecting rod head 13 is equal with the cone angle of the frustoconic shape of groove 10, the degree of depth of groove 10 equals the height of connecting rod head 13, groove 10 base diameter is slightly less than connecting rod head 13 lower end surface diameter, groove 10 is connected with connecting rod head 13 bolt, time initial, groove 10 is connected bottom rear groove 10 with connecting rod head 13 bolt and leaves a part of space.
The working procedure of this push type time-delayed self-turning off tap is as follows: pressing pressure cap 7 downwards, compression reaction spring 8, drivening rod 11 and close water bolt 9 and move downward, open initially by the water inlet 6 closed water bolt 9 and block, current flow into water chamber 4 by intake pipe 1, water-inlet cavity 3 under hydraulic pressure, and then flow out outlet pipe 2.Stop downwards after pressing pressure cap 7, under the effect of returning spring 8, pressure cap 7 slowly floats, drivening rod 11 and close water bolt 9 and move upward, and gets back to original state, closes water bolt 9 and block water inlet 6, thus stop water outlet.After this water tap Long-Time Service, to close outside water bolt 9 due to excessive wear, cause closing water imprecision, occur leaking, seeping water phenomenon.And after closing water bolt 9 wearing and tearing, reduce with the frictional force of water chamber 4 madial wall owing to closing water bolt 9, water tap resilience fast after pressing can be caused again, lose the function that water is closed in time delay.Now, pressure cap 7 can be pressed down, make the bottom close contact closing water bolt 9 and water chamber 4, with screw-driver firmly downward turn connecting rod cap 12, drivening rod 11 and connecting rod head 13 rotate descending suitable stroke, because groove 10 base diameter is slightly less than connecting rod head 13 lower end surface diameter, therefore groove 10 radially can be strutted, what extrude quality of rubber materials closes water bolt 9 radial outward expansion, thus strengthen the pressure closed between water bolt 9 and water chamber 4 madial wall, make to close water bolt 9 and again keep close contact with the madial wall of water chamber 4, elimination is leaked, infiltration phenomenon, increase the frictional force of closing between water bolt 9 and water chamber 4 madial wall simultaneously, eliminate the phenomenon of water tap resilience fast after stopping pressing, recover the function that water is closed in its time delay, eliminate after tested and leak, the downward turn of screw-driver can be stopped after the phenomenon of infiltration and resilience fast after stopping pressing.After this leak, seep water or stop the phenomenon of resilience fast after pressing in using as again occurred, again can carry out aforesaid operations, stop until connecting rod head 13 lower end surface is met bottom groove 10.Such scheme substantially prolongs the working life of push type time-delayed self-turning off tap, and structure is simple, easily processes, cost-saving.In addition, this push type time-delayed self-turning off tap can also pass through with screw-driver turn connecting rod cap 12 downward or upward in routine use process, regulate and close the degrees of expansion of water bolt 9 in its radial direction, and then regulate the pressure size of closing between water bolt 9 and water chamber 4 madial wall, regulate the speed stopping pressing rear pressing cap 7 to float, reach the effect regulating delay duration.
