Abstract
The invention relates to an O-shaped sealing ring. An O-shaped sealing ring for sealing a water path comprises an O-shaped sealing ring body, wherein an annular water storage tank is formed in the inner side of the O-shaped sealing ring body in the radial direction; the depth of the annular water storage tank is 60-70% of the line diameter of the O-shaped sealing ring body; the width of the annular water storage tank is 30-40% of the line diameter of the O-shaped sealing ring body; and a water inlet notch which is communicated with the annular water storage tank is formed in an axial compression inner end face of the O-shaped sealing ring body. The O-shaped sealing ring for sealing the water path disclosed by the invention has the advantages of novel structure, long service life and good sealing performance.
Description
Technical field
The present invention relates to a kind of O RunddichtringO.
Background technique
Every product that relates to water, on connecting, water route all to consider the sealing problem to water, all the more so with the direct-connected product of water supply pipe, the pressure of tap water supply system is generally the 2-5 kilogram, can be higher in the time of at dead of night, in a single day can not get ensureing, leaking as the sealability of fruit product on water route connects, consequence is with hardly imaginable.The seal approach that is used at present the water route sealing is that a cross section is set in the joint, water route is solid O RunddichtringO, then by other mechanism, in axial or footpath, upwards gives O RunddichtringO certain pressure and makes its modification, thereby realize sealing.Such O RunddichtringO fatigue resistance is poor, during the joint that often changes especially for needs, and long-time the use namely after compressed many times, its elasticity can become worse and worse, and the risk of leaking improves; On the other hand, the O RunddichtringO is generally to be made by materials such as butyronitrile rubber or silica gel, and working life is short, and is of long duration easy to be aging, if change not in time or safeguard, easily leaks.
Summary of the invention
The objective of the invention is the deficiency that exists in order to solve the above-mentioned existing O RunddichtringO that is used for the water route sealing, provide a kind of novel structure, long service life, the O RunddichtringO that is used for the water route sealing of good seal performance.
In order to realize above-mentioned purpose, the present invention has adopted following technological scheme:
The O RunddichtringO that is used for the water route sealing, comprise O RunddichtringO body, the radially inner side of O RunddichtringO body is provided with annular aqua storage tank, and the degree of depth of annular aqua storage tank is the 60%-70% of O RunddichtringO body wire diameter, and the width of annular aqua storage tank is the 30%-40% of O RunddichtringO body wire diameter; The axial compression interior edge face of O RunddichtringO body is provided with the water inlet breach that is communicated with annular aqua storage tank.
As preferably, the water inlet breach that described and annular aqua storage tank is communicated with is regularly arranged a plurality of on the axial compression interior edge face of O RunddichtringO body, can rule intake, makes more balance of the interior water pressure of annular aqua storage tank.
As preferably, described water inlet breach is 4, and is convenient for production.
Adopted the O RunddichtringO that is used for the water route sealing of above-mentioned technological scheme, water enters annular aqua storage tank by the water inlet breach, when the hydraulic pressure in flow channel increased, the hydraulic pressure in annular aqua storage tank can make the O RunddichtringO be in the state of " expansion ", and the larger sealing effect of hydraulic pressure is better.The degree of depth of annular aqua storage tank is the 60%-70% of O RunddichtringO body wire diameter, the width of annular aqua storage tank is the 30%-40% of O RunddichtringO body wire diameter, the volume of annular aqua storage tank is large and intensity O RunddichtringO body is high, and namely the balance of volume and intensity reaches best.When the hydraulic pressure in flow channel diminishes or disappears, act on that pressure in the annular aqua storage tank of O RunddichtringO is also corresponding to be reduced or disappear, the O RunddichtringO is in free state, need not be in for a long time compressive state, and also can significantly improve its working life.In sum, the advantage that should be used for the O RunddichtringO of water route sealing is novel structure, long service life, good seal performance.

Fig. 3: the O RunddichtringO for the water route sealing of the present invention uses view.
Embodiment
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the specific embodiment of the present invention is made a detailed explanation.
The O RunddichtringO that is used for the water route sealing as depicted in figs. 1 and 2, comprise O RunddichtringO body 1, the radially inner side of O RunddichtringO body 1 is provided with annular aqua storage tank 3, the degree of depth of annular aqua storage tank is the 60%-70% of O RunddichtringO body wire diameter, and the width of annular aqua storage tank is the 30%-40% of O RunddichtringO body wire diameter.The axial compression interior edge face of O RunddichtringO body 1 is provided with 4 water inlet breach 2 that are communicated with annular aqua storage tank 3, and 4 water inlet breach 2 that are communicated with annular aqua storage tank 3 are regularly arranged on the axial compression interior edge face of O RunddichtringO body 1.Relatively the wire diameter of O RunddichtringO body 1 commonly used is 4mm, and the degree of depth of annular aqua storage tank is 2.5mm, and the width of annular aqua storage tank is 1.3mm.
During use, as shown in Figure 3, the O RunddichtringO that is used for the water route sealing is arranged between link 1 and link 25, and the water 6 in flow channel enters in annular aqua storage tank 3 by water inlet breach 2.When having certain hydraulic pressure in flow channel, can produce the hydraulic pressure that equates after annular aqua storage tank 3 water storages, hydraulic pressure makes the O RunddichtringO be in the state of " expansion ", and the larger sealing effect of hydraulic pressure is better.The O RunddichtringO is compacted with the position that contacts of link 1, link 25, and hydraulic pressure is larger, and the sealing effect of O RunddichtringO is better.When the hydraulic pressure in flow channel diminishes or disappears, act on that the pressure of O RunddichtringO is also corresponding to be reduced or disappear, the O RunddichtringO, in free state, need not be in compressive state for a long time, and also can significantly improve its working life.
