It can effectively prevent the sprinkler tip of sealing ring Yu frame adhesion.
To achieve the above object, The technical solution adopted by the invention is as follows: a kind of sprinkler tip of anti-seal circle adhesion, packet
Frame, seal receptacle, temperature-sensitive element and splash box are included, the framework upper includes the inlet and outlet connecting with water pipe, institute
It states seal receptacle to connect by the support of temperature-sensitive element with water outlet, it is characterised in that: the water outlet is provided with cricoid close
Sealing groove, is provided with sealing ring in the seal groove, and the seal groove diameter is greater than water outlet diameter, and sealing ring and seal receptacle it
Between there are space, the sealing groove height is not more than sealing ring diameter of section.
Preferably, the seal receptacle is inverted " T-shaped structure ", and the seal receptacle upper diameter is less than in sealing ring
Diameter.
Preferably, the water inlet diameter is greater than water outlet and internal diameter is gradually reduced by inlet end to water outlet end.
Preferably, the seal receptacle top is provided with groove.
By using above-mentioned technical proposal, the beneficial effects of the present invention are: by be arranged seal groove give sealing ring with it is close
It seals and forms a space between seat, enable water to full of the space and directly contacted with sealing ring, it is old to slow down sealing ring
The speed of change and the heated generation for melting caused adhesion phenomenon.By changing outlet structure, solve in the prior art
High production cost and installation procedure is cumbersome and critical component can only pass through the technical problems such as import.Effective solution sealing ring is viscous
Even key technical problem in this industry, and all kinds of costs are controlled to the full extent.
Detailed description of the invention
Fig. 1 is the structure sectional view of the sprinkler tip of the anti-seal circle adhesion of one kind provided by the invention.
Specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Such as Fig. 1, a kind of sprinkler tip of anti-seal circle adhesion, including frame 1, seal receptacle 2, temperature-sensitive element 7 and splash box
8,1 top of frame includes the water inlet 11 and water outlet 12 connecting with water pipe, and the seal receptacle 2 passes through temperature-sensitive element 7
Support is connect with water outlet 12, it is characterised in that: cricoid seal groove 4, the seal groove 4 are provided at the water outlet 12
It is inside provided with sealing ring 3,4 diameter of seal groove is greater than 12 diameter of water outlet, and there is sky between sealing ring 3 and seal receptacle 2
Between, 4 height of seal groove is not more than 3 diameter of section of sealing ring.By adding seal groove 4, and will directly be extruded in out originally
Sealing ring 3 between the mouth of a river 12 and seal receptacle 2 is set between seal groove 4.While so that sealing ring 3 is kept its sealability,
Mitigate water outlet 12 and seal receptacle 2 to the pressure of sealing ring 3.The deformation degree of sealing ring 3 can be effectively reduced, is reduced old
Change speed.Since 4 diameter of seal groove is greater than water outlet 12, and a space is formed between sealing ring 3 and seal receptacle 2.Water can
To pour into the space, and direct covering is generated to a part of sealing ring 3.The case where this covering, can be effectively to close
Seal 3 carries out water seal, and effective solution adhesion phenomenon because of caused by 3 aging of sealing ring enhances 3 service life of sealing ring.Together
When, continual cool is carried out to sealing ring 3 by the covering of water.Enable sealing ring 3 that can occur in temperature-sensitive element 7 dynamic
Guarantee not heated always before making.Effectively solving the very fast raising of temperature when daily room temperature is excessively high or on fire leads to sealing ring 3
Adhesion problems caused by heated thawing.
Such as Fig. 1, the seal receptacle 2 is inverted " T-shaped structure ", and 2 upper diameter of seal receptacle is less than in sealing ring 3
Diameter.Pass through above structure effective solution adhesion problems.But the sealing ring 3 not limited by 2 edge of seal receptacle is possible to direct
