It can guarantee with aquatic products excessively and do not burst, but under conditions of some are special, such as under less than 0 DEG C scene of high pressure or temperature
When, usually because internal pressure is excessive or frost leads to pipeline or crosses the explosion of aquatic products, so that water is constantly flowed out in this way, cause
The waste of water resource, while it being likely to occur the case where house is immersed in water, bring many troubles to owner.
Invention content
In order to solve the above-mentioned technical problem, the purpose of the present invention is to provide a kind of explosion-proof water installations excessively.
The present invention is achieved through the following technical solutions：
One kind is explosion-proof to cross water installations, including the inner and outer tubes being arranged inside and outside, and piston is provided between said inner tube and outer tube
Ring, the piston ring can be moved along the axial line of inner tube, and a discharge orifice, the movement of the piston ring are arranged on the outer tube peripheral wall
The connection of appearance water inlet end and discharge orifice can be opened and closed.
It in the embodiment of the present invention, is connected through a connection piece between said inner tube periphery and outer tube inner circumferential, the piston ring is set
The periphery at interior water inlet tube end is set, coupling between the piston ring and connector has spring.
In the embodiment of the present invention, the connector is a connection ring, the connection ring inner ring and inner tube water outlet side
Periphery wall is connected, and the connection ring outer ring is connected with outer tube internal perisporium.
In the embodiment of the present invention, the spring is set in inner tube periphery, and spring one end is engaged with connection ring end face.
In the embodiment of the present invention, the periphery wall of the piston ring is provided with and matched first sealing of outer tube internal perisporium
Circle, said inner tube periphery wall are provided with and matched second sealing ring of the internal perisporium of piston ring.
In the embodiment of the present invention, the piston ring is towards the step for being provided with an annular on the end face of inner tube water outlet side
The other end in face, the spring couples with step surface cooperation.
One kind of the present invention is explosion-proof to cross water installations, has the advantages that：It is explosion-proof antifreeze everywhere in applicable household water,
Overall structure occupies little space.
Description of the drawings
It, below will be to required in embodiment or description of the prior art in order to illustrate more clearly of technical scheme of the present invention
The attached drawing used is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, right
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
Its attached drawing.
Fig. 1 is the explosive view of the present invention.
Fig. 2 is the sectional view of the present invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, is carried out to the technical solution in inventive embodiments clear, complete
Ground describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, the every other reality that those of ordinary skill in the art are obtained without making creative work
Example is applied, shall fall within the protection scope of the present invention.
Reference explanation book attached drawing, one kind is explosion-proof to cross water installations, including the inner tube 10 and outer tube 20 being arranged inside and outside, described interior
It is provided with piston ring 30 between pipe and outer tube, the piston ring can be moved along the axial line of inner tube, be arranged one on the outer tube peripheral wall
Discharge orifice 21, the mobile connection that can open and close appearance water inlet end and discharge orifice of the piston ring, under normal water pressures, water
Stream is directly flowed out from inner tube, and discharge orifice at this time does not work, and when hydraulic pressure reaches certain value, hydraulic pressure forces piston ring toward water
The direction of stream is moved, and so that flow is flowed to relief hole and is carried out pressure release, the pressure in the device is made not exceed the limiting value of explosion.
During a use, it is connected through a connection piece 40 between said inner tube periphery and outer tube inner circumferential, the piston ring
Periphery at interior water inlet tube end is set, and coupling between the piston ring and connector has spring 50, when the hydraulic pressure in the device reduces
When to safety value, piston ring cuts off flow and flows to discharge orifice under the action of the spring, and the device is made normally to work.Specifically
It says：The connector is a connection ring, and the connection ring inner ring and the periphery wall of inner tube water outlet side are connected, the connection
Ring outer ring is connected with outer tube internal perisporium.The spring is set in inner tube periphery, and spring one end is contacted with connection ring end face matches
It closes.
In order to ensure that flow does not flow to discharge orifice under the pressure of normal flow, the periphery wall of the piston ring be provided with
Matched first sealing ring 61 of outer tube internal perisporium, said inner tube periphery wall are provided with and the internal perisporium of piston ring matched
Two sealing rings 62.The piston ring is towards the step surface 31 for being provided with an annular on the end face of inner tube water outlet side, the bullet
The other end of spring couples with step surface cooperation.
In the present invention：Links of the product suitable for family water route.When hydraulic pressure reaches setting value, piston ring is in water
It is pushed under the action of pressure pressure, allows product that there is bearing capacity, if pressure reaches the limit values, interiors of products pressure passes through outer
The discharge orifice pressure release of pipe side wall, to reach explosion-proof.It is swollen when interiors of products liquid is down to solidification point and leads to volume expansion
Swollen pressure can also promote the movement of piston ring, to make water inlet end be connected with discharge orifice, can equally reach explosion prevention function.
In a preferred embodiment of the present invention, the size of bearing area and bearing area can be changed according to use environment, which be
Piston ring is towards the end face of water inlet end, it is also assumed that being the area between inner and outer tubes, so that entire blast resistance construction is more
Step up to gather.
The preferred embodiment of the present invention has shown and described in above description, as previously described, it should be understood that the present invention is not office
Be limited to form disclosed herein, be not to be taken as excluding other embodiments, and can be used for various other combinations, modification and
Environment, and can be changed by the above teachings or related fields of technology or knowledge in the scope of the invention is set forth herein
It is dynamic.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then it all should be appended by the present invention
In scope of the claims.
