Description

Soft sealing plunger

Technical Field

The utility model belongs to thermostatic cartridge field relates to a plunger, in particular to soft sealing plunger.

Background

As a core device for regulating water temperature, the thermostatic valve core is widely applied to a thermostatic water heater and a thermostatic faucet. When the water pressure of hot water or cold water changes suddenly or the temperature of hot water changes suddenly, the thermostatic regulating valve core can automatically balance the water pressure of the cold water and the hot water in a short time, so that the temperature of mixed water can be automatically kept at a set temperature to keep the temperature of outlet water stable. The plunger is positioned in the thermostatic valve and is matched with the temperature sensing element to play a core device for adjusting the cold-heat matching ratio, and when cold water or hot water fails, the plunger can close the other path of water under the action of the temperature sensing element to prevent the thermostatic valve core from discharging water, so that the scald or the frostbite of a human body can be prevented.

The upper end face and the lower end face of the traditional thermostatic plunger are made of rigid materials, the upper end face and the lower end face of the traditional thermostatic plunger are not easily attached to a valve core sealing surface tightly, the thorough cutting water cut-off effect is difficult to achieve under the condition that cold water and hot water fail, the flatness processing requirement between the upper end face and the lower end face of the traditional thermostatic plunger and the sealing surface corresponding to the valve body is high, and the flatness of the valve body sealing surface can be reduced after the thermostatic plunger works for a long time.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide a sealed face of plunger that comprises flexible material, make and reach the leakproofness better, the longer soft sealing plunger of life.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a soft sealing plunger, its characterized in that includes plunger main part and the sealing ring that comprises flexible material, the arrangement recess that supplies the embedding of corresponding sealing ring is all seted up at the upper and lower both ends of plunger main part, the plunger main part on seted up along its circumferencial direction with cold, hot water separated water proof ring mounting groove, the plunger main part in seted up the installation thread groove with temperature-sensing element threaded connection, the plunger main part in still seted up a plurality of and be the water hole of crossing of circumference interval distribution.

In the soft sealing plunger, the sealing rings at the upper end and the lower end of the plunger are respectively an upper sealing ring and a lower sealing ring, the upper end surface of the upper sealing ring forms an upper sealing surface with a soft sealing effect, and the lower end surface of the lower sealing ring forms a lower sealing surface with a soft sealing effect.

In one of the above soft seal plungers, the plunger body and the seal ring are integrally formed to form a one-piece plunger member.

In the above soft sealing plunger, the mounting grooves are provided with a plurality of fixing holes communicated with the outside.

In the above soft seal plunger, the seal ring is made of soft rubber.

Compared with the prior art, the soft sealing plunger has the following advantages:

1. the sealing rings symmetrically arranged up and down in the plunger main body are made of soft rubber materials and are integrally formed with the plunger main body to form an integral plunger element, so that the abrasion degree of the plunger during up-and-down movement and adjustment in the valve core is reduced, and the service life of the plunger is prolonged;

2. elastic deformation's characteristic through flexible material itself has, the sealing ring at both ends produces elastic deformation under the effect of external force about the plunger, form a flexible seal's effect, make the sealing ring thoroughly laminate on the sealed face of relative unevenness about the case, after external force gets rid of, elastic deformation disappears, go up the sealing ring and all reply initial condition with lower sealing ring, make the leakproofness of plunger reset, the water clearance of plunger and case is unchangeable, the rigidity that constitutes relative traditional single material sealed plunger has higher stability, better leakproofness and longer life.
