Abstract
The utility model discloses a temperature-control valve core mainly comprising a valve core body, an adjusting piece, a metal rod, a locknut, a spring and a plug. By adopting two O-rings which are arranged at the contact part of the valve core body and the outer surface of the adjusting piece and at the contact part of the metal rod and the locknut and by increasing two rings for double protection, the temperature-control valve core has the advantages that the sealing performance is excellent, no water leakage occurs, the product performance can be improved and the service life is prolonged.
Description
Technical field
The utility model relates to the thermostat valve field, refers specifically to a kind of temperature controlled valve core structure.
Background technique
Thermostat valve is the topmost regulating equipment of heating system Flow-rate adjustment, also claims thermostatic control valve, and heating system is by the hot water flow in the thermostat valve control radiator, thereby the assurance room temperature is relatively more balanced.
Existing temperature controlled valve core structure is referring to shown in the accompanying drawing 1, and valve body 1 mainly relies on O RunddichtringO 11 to realize with the sealing of steel pole 10, and valve body 1 mainly relies on O RunddichtringO 13 to realize with the sealing of copper split nut 12.The temperature controlled valve core of said structure only is provided with one seal ring protection; sealing intensity is not high; in the use; in case O RunddichtringO 11 damages; will occur leaking in a large number at the junction point of copper split nut 12,, will occur leaking in a large number at the junction point of copper split nut 12 with valve body 1 in case O RunddichtringO 13 damages with steel pole 10; the integral product poor performance, working life is short.And the not predeterminable adjusting water flow of existing temperature controlled valve core, influenced the normal use of thermostat valve.
The model utility content
The purpose of this utility model is to provide a kind of temperature controlled valve core, and it has good sealing property, predeterminablely decides water flow.
In order to achieve the above object, the utility model is realized by following technological scheme.
A kind of temperature controlled valve core, mainly comprise valve core, adjusting element, metallic rod, locking nut, spring and plug, it is characterized in that: adjusting element is assemblied in the valve core, adjusting element can be in valve core mobile lifting, be provided with the O RunddichtringO in the contacting point of valve core and adjusting element outer surface; The sheathed spring section of metallic rod is located in the adjusting element, and metallic rod one end exposes adjusting element, and the metallic rod the other end passes the locking nut that is fixedly arranged in the adjusting element and is connected with plug; Be provided with the O RunddichtringO in the contacting point of metallic rod and adjusting element, be provided with the O RunddichtringO in the contacting point of metallic rod and locking nut.
Described contacting point at valve core and adjusting element outer surface is provided with two O RunddichtringOs.
Described contacting point at metallic rod and locking nut is provided with two O RunddichtringOs.
Describedly be located at locking nut in the adjusting element and the contacting point of adjusting element is provided with the O RunddichtringO.
The utility model beneficial effect is; employing is provided with two O RunddichtringOs in the contacting point of contacting point, metallic rod and the locking nut of valve core and adjusting element outer surface; can play duplicate protection by increasing the two seals circle; it has good sealing property; can not produce and leak; can enhance product performance, increase the service life.The utility model adjusting element can be at the valve inner mobile lifting, thereby can preset the water flow size.
