Abstract
The utility model provides a ball type valve inside. The valve inside body is a cavity structure. The ball valve body abuts with the internal opening of the inside valve body inlet passage, forming the sealed sphere. One end of the return spring is fixed in the cavity while the other end abuts with the ball valve body, forming a one-way valve structure. When the air current enters from the inlet passage, the air current can overcome the elastic force of the spring to open the ball valve body for inflation. When the air current enters in the opposite direction, the ball valve body can closely abut with the internal opening of the airflow passage to prevent the air current from leaking outwards. Thus, the one-way valve function of the valve inside is completed. The ball valve body structure ensures that the valve body is combined with the inlet passage forming the sealed sphere. No matter how the ball valve body position changes, the inlet passage can be sealed thoroughly to prevent the gas from leaking. Thus, the gas leakage phenomenon is avoided due to the valve body deviation from the inlet passage. The normal operation of the valve inside is ensured.
Description
Technical field
The utility model is to the improvement of existing valve inside, and a kind of ball formula valve inside is provided, and belongs to pneumatic tire component technical field.
Background technique
Existing tyre valve core be generally rubber plug structure, often occur rubber stopper in actual use and depart from valve, cause gas leak phenomenon, reliability is relatively poor, often owing to have a flat tire and much bother to the daily living voice band of people.
Summary of the invention
The utility model provides a kind of ball formula valve inside, has overcome the phenomenon generation of eccentric gas leakage easily of rubber stopper formula valve inside.
Technical solution of the present utility model is as follows: the valve inside body is a cavity structure, be provided with spherical valve body and Returnning spring in the chamber, wherein, spherical valve body withstands on the internal orifice of valve inside body gas-entered passageway and forms ball face sealing, Returnning spring one end is fixed in the cavity, the other end withstands on and constitutes one-way valve structures on the spherical valve body, when air-flow when the inlet stream passage enters, the elastic force that air-flow overcomes spring backs down spherical valve body, inflate, when air-flow oppositely enters, then spherical valve body is pressed closer on the air-flow path internal orifice, prevented that air-flow from leaking, finished the non-return valve function of valve inside.
Good effect of the present utility model is: adopt the spherical valve body structure, make valve body and gas-entered passageway constitute ball face sealing, no matter how displacement of spherical valve body, all gas-entered passageway can be sealed fully, prevented gas leakage, overcome because of valve body and gas-entered passageway depart from gas leak phenomenon has taken place, guaranteed the proper functioning of valve inside.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Embodiment
According to shown in Figure 1, valve inside body 4 is a cavity structure, front end is provided with gas-entered passageway 1, the internal orifice of gas-entered passageway 1 is taper, spherical valve body 2 is made and is withstood on by steel ball on the internal orifice of gas-entered passageway 1 and forms ball face sealing, Returnning spring 3 one ends are fixed in the valve inside cavity 4, and the other end withstands on the spherical valve body 2 and constitutes one-way valve structures.
Claims (1)
