Abstract
The utility model relates to an O-shaped seal ring. The O-shaped seal ring which is used for waterway sealing comprises an O-shaped seal ring body, wherein an annular water storage tank is formed on the radial inner side of the O-shaped seal ring body, the depth of the annular water storage tank is 60-70% of the line diameter of the O-shaped seal ring body, the width of the annular water storage tank is 30-40% of the line diameter of the O-shaped seal ring body, and a water inlet gap communicated with the annular water storage tank is formed in the axial compression inner end surface of the O-shaped seal ring body. The O-shaped seal ring provided by the utility model has the advantages of novel structure, long service life and good sealing performance.
Description
Technical field
The utility model 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, once leak as the sealability of fruit product on water route connects can not get ensureing, consequence is by hardly imaginable.For the seal approach of water route sealing, be at present that a cross section is set in the joint, water route is solid O RunddichtringO, then by other mechanism, in axial or footpath, upwards give O RunddichtringO certain pressure and make 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 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, of long duration easy to be aging, if change not in time or safeguard, easily leaks.
Summary of the invention
Goal of the invention of the present utility model is in order to solve the above-mentioned deficiency had now for the O RunddichtringO existence of water route sealing, a kind of novel structure to be provided, long service life, the O RunddichtringO for the water route sealing of good seal performance.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
O RunddichtringO 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 be 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, convenient for production.
Adopted the O RunddichtringO 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 increases, the hydraulic pressure in annular aqua storage tank can make the state of O RunddichtringO in " 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 the balance of volume and intensity reaches best.Hydraulic pressure in flow channel diminishes or while disappearing, and acts on that pressure in the annular aqua storage tank of O RunddichtringO is also corresponding to be reduced or disappear, and the O RunddichtringO, need not be for a long time in compressive state in free state, and also can significantly improve its working life.In sum, the advantage of the O RunddichtringO that should seal for water route is novel structure, long service life, good seal performance.

Fig. 3: the O RunddichtringO for the water route sealing of the present utility model is used view.
Embodiment
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, embodiment of the present utility model is made a detailed explanation.
The O RunddichtringO 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.The wire diameter of O RunddichtringO body 1 more 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 sealed for water route 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.While in flow channel, having certain hydraulic pressure, after annular aqua storage tank 3 water storages, can produce equal hydraulic pressure, hydraulic pressure makes the state of O RunddichtringO in " 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.Hydraulic pressure in flow channel diminishes or while disappearing, and acts on that the pressure of O RunddichtringO is also corresponding to be reduced or disappear, and the O RunddichtringO, need not be for a long time in compressive state in free state, and also can significantly improve its working life.
