Description
Technical field
This utility model relates to the valve of a kind of domestic water circuit system, more specifically, it relates to a kind of check valve.
Background technology
Check valve is a kind of common pipeline valve, is mostly arranged on the heating system of closed cycle or the water pipe of refrigeration system, can be used for keeping system pressure a stationary value, for instance on wall-hung boiler, floor heating, miniature boiler, central air conditioning water system.
When the pipeline in floor heating blocks, the hydraulic pressure in pipeline will raise, and is at this moment accomplished by using check valve, is delivered to by check valve by the water in pipeline in other loop, it is to avoid cause pipeline breaking because hydraulic pressure is too high.
At present, application number be 201510690347.8 Chinese patent disclose a kind of convenient check valve cleaned, it includes valve body, oil-in is arranged at the top of valve body, oil-out is arranged at the top of body wall, the spring base arranged below of body cavity, spring base has the spring towards oil-in, that section of spring correspondence oil-in there is spherical spool, by the pressure of spring, spool is acted against on oil-in, when the pressure on pipeline increases, spool is moved by the liquid in pipeline, so that liquid enters from oil-in, then discharges from oil-out.Although this convenient check valve simple in construction cleaned, but owing to the use time of spring is long, often make the elastic reduction of spring, cause the liquid in pipeline that spool just can be driven under less hydraulic pressure to move, namely the hydraulic pressure in pipeline cannot be remained stable for by check valve, now it is accomplished by being replaced the spring in valve body, and the spring under changing just can only abandon, and causes the wasting of resources.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of check valve that can regulate pipeline pressure.
For achieving the above object, this utility model provides following technical scheme: a kind of check valve, including valve body and spool, described valve body offers water inlet and outlet, described spool is connected to elastic component, and described elastic component one end is connected with spool, and the other end is connected to mounting seat, described mounting seat coordinates with valve body, and described elastic component is provided with the telescoping mechanism for regulating elongation and the limit assembly for telescoping mechanism location.
By adopting technique scheme, when the elastic component elasticity in check valve reduces, the elongation of elastic component is regulated by telescoping mechanism, make elastic component because of the change of elongation thus improving elastic force, the pressure of water inlet is improved by spool, so that the liquid in pipeline can by spool jack-up after bringing up to certain hydraulic pressure again, it is that current enter from water inlet, outlet flows out, thus the pressure in pipeline is played stable effect, and the elastic component without more renewing, do not result in the wasting of resources, thus having saved cost.
This utility model is further arranged to: described telescoping mechanism includes for connecting the first connector of elastic component, the second connector and for driving the runner assembly of the first connector, the second connector displacement.
By adopt technique scheme, the rotation of runner assembly, is that the distance between the first connector and the second connector is increased or reduces, from but elastic component produce deformation, then make the elastic force of elastic component increase because of the deformation of elastic component.
