Abstract
The utility model discloses a valve core which comprises a valve core body. A sealing ring is sleeved on the outside of the valve core body. The valve core is characterized in that a circle of flange is arranged between the valve core body and the sealing ring. The sealing ring can be clamped at a fixed position and prevented from sliding by the flange, external impurities can be hindered above the flange and can be prevented from dropping into a lower core seat, and sealing performance of the sealing ring is improved.
Description
Technical field
The utility model relates to a kind of valve inside core body, belongs to the valve inside technical field.
Background technology
The core body outside of valve inside can be with a circle seal ring usually, and one plays sealing function.Because seal ring is a rubber structure; And the core body of valve inside is a metal construction; Not between the two bonding very infirm, and, influence sealing effectiveness because seal ring slides; Extraneous simultaneously meetings such as dust impurity are called in the core print seat of below through the gap of seal ring and core body, have influenced the use of valve inside.
The utility model content
The utility model relates to a kind of valve inside core body, produces sliding phenomenon in order to solve between traditional valve inside core body and the seal ring, influences the problem of sealing effectiveness.
For realizing this purpose, the method that the utility model adopted is: a kind of valve inside core body, comprise body, and it is characterized in that between body and seal ring, be provided with a circle flange, said flange (2) is formed in one with body on body.
Its beneficial effect is: flange can say that seal ring blocks, and prevents its slippage, intercepts introduced contaminants simultaneously, improves sealing effectiveness.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the utility model semisectional view.
The specific embodiment
Disclosed all characteristics in this specification sheets, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification sheets (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1, a kind of valve inside core body comprises body 1, between body 1 and seal ring 3, is provided with a circle flange 2, and flange 2 is on body 1, and is one-body molded with body 1.Flange 2 blocks seal ring 3, prevents its slippage, and the impurity with the external world intercepts above flange 2 simultaneously, prevents that impurity from falling into, and improves the sealing effectiveness of seal ring 3.
The utility model is not limited to the aforesaid specific embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
Claims (2)
1. a valve inside core body comprises body (1), and body (1) is outer to be with a seal ring (3), it is characterized in that, between said body (1) and seal ring (3), is provided with a circle flange (2).
2. a kind of valve inside core body according to claim 1 is characterized in that, said flange (2) is formed in one with body (1) on body (1).
