Description
Technical field
The utility model relates to a kind of one-way valve that is used for massaging pool or bathing pool, is specifically related to a kind of one-way valve sealing configuration.
Background technique
One-way valve is the common components in the conduit pipeline in jacuzzi or pond, is installed on usually on the pipeline between the annular air channel in control box and jacuzzi or pond, is used to control the flow direction of massage with gas, prevents that the water in the body of pond from refluxing.China Patent No. ZL200920208571.9, name are called in the utility model patent of " one-way valve " has described two kinds of traditional one-way valves, a kind of traditional one-way valve wherein as shown in Figure 1, comprising valve body 1, being arranged at a end in the valve body 1 is that the mast 21 and the other end are the spring 3 on the mast 21 of the spool 2 of spherical column cap 22, the seal ring 4 that is arranged at valve body 1 top and sheathed and spool 2, the column cap 22 of described spool 2 is a spherical, and described seal ring 4 contacts by the sphere with described spherical column cap 22 and realizes sealing.When ventilation, gas presses down spool 2, pushes spring 3, and the spherical column cap 22 of spool 2 separates with seal ring 4, and gas enters in the one-way valve, feeds the annular air channel in jacuzzi or pond then by connecting tube.When stopping to ventilate, the elastic force effect of spring 3 is pushed the column cap 22 of spool 2 to seal ring 4, and the slip of column cap 22 spheres contacts with seal ring 4 and realizes sealing, prevents that the water in the body of pond from refluxing.Realize in this one-way valve that the structure that seals mainly is arranged on the seal ring 4 on valve body 1 top and the spherical column cap 22 of spool 2 matches, promptly match by the sphere of the side margin on the seal ring 4 with the spherical column cap 22 of spool 2, the formation line contacts with face, realizes sealing.Because the preparation process of sphere is difficult to control, sphere is difficult to make rounding, like this will be because of sphere rounding and cause seal ring 4 and spool 2 column caps 22 ball face sealings unreliable and cause the one-way valve backwater not.
Another kind of traditional one-way valve of describing in the above-mentioned utility model patent as shown in Figure 2, the structure of the one-way valve among its structure and Fig. 1 is similar basically, different places is that the column cap 202 of the spool 20 of the one-way valve among Fig. 2 is designed to cylinder type, its outer surface contacts with the internal surface of seal ring 40 and realizes sealing, and area of contact is bigger.The structure that realizes sealing in this one-way valve mainly is that the internal surface by seal ring 40 contacts with the outer surface of spool 20 column caps 202 and realizes sealing, area of contact is bigger, when for a long time need not in the pond, two faces just are bonded together easily, cause one-way valve not open, can't be to jacuzzi or pond ventilation.Therefore, need the sealing configuration of existing one-way valve be improved.
The model utility content
The purpose of this utility model just is to provide a kind of one-way valve sealing configuration, and the sealing configuration that has one-way valve now is unreliable, sealing effect is relatively poor and the flimsy defective of sealing configuration to overcome.
One-way valve sealing configuration of the present utility model, comprise that one-way valve and one-way valve upper end is connected to the pipeline of inflation inlet, described one-way valve comprises that valve body, spool and spool below are used for the spring of contact spool, and described spool comprises valve rod and the set valve head of valve stem tip, wherein
The top of described valve head is a ball-crown body, and the below of described ball-crown body is provided with one first round platform, also is provided with one first annular slot between the described ball-crown body and first round platform, and a sealing snare is stuck in described first annular slot;
The lower end that described one-way valve upper end is connected to the pipeline of inflation inlet is provided with a ring packing line corresponding to described seal ring, the diameter of sealing line is realized sealing to be used for contacting with described seal ring between the external diameter of the external diameter of the bottom surface of described ball-crown body and described seal ring.
Further, first round platform of described valve head below also is provided with second round platform, is provided with one second annular slot between described second round platform and first round platform, is used for fixing the described upper end that is used for the spring of contact spool.
The external diameter of described second round platform is less than the external diameter of described first round platform.
Compared with prior art, the beneficial effect that the utlity model has is:
1, one-way valve sealing configuration of the present utility model is to adopt the ring packing line on the valve body to contact cooperation with the face of seal ring and realize sealing, this fitted seal mode, sealing effect are better than the mode and the effect of the contact seal of traditional seal ring and column cap sphere, can overcome that rounding causes the contact seal of sphere and seal ring unreliable owing to traditional spool column cap sphere is made not, thereby improve reliability of products;
2, compare with the preparation process of traditional column cap sphere, the preparation process of the ring packing line on the valve body is more easy.
