Abstract
The utility model discloses a valve body. The valve body comprises a main body, a joint hole is formed in the main body, the inner end portion of the joint hole is a small tapered end, and the outer end of the joint hole is a straight hole. An annular groove is formed in the inner wall of the main body and located at the end opening of the joint hole, and is parallel to a main hole. The valve body can overcome the defects of existing products, is simple in structure, and can protect a sealing ring and promote the sealing effect.
Description
Technical field
The utility model relates to a kind of valve body.
Background technique
Seen stop valve in the market, valve body structure on it exists not enough, when spool moves up and down by nipple orifice, because the pressure that is subjected between seal ring and the valve interior wall is inhomogeneous, one side is nipple orifice, seal ring is not produced pressure, so cause sealing between seal ring and the valve interior wall asymmetric, sealing effect reduces greatly, haves much room for improvement.
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the inventor has done deep research, and by feat of the experience of being engaged in relevant industries for many years and practice; design a kind of valve body, can solve the deficiency in the existing product, simple in structure; the protection seal ring improves sealing effect simultaneously, and this case produces thus.
The model utility content
The purpose of this utility model is to provide a kind of valve body, can solve the deficiency in the existing product, and is simple in structure, and the protection seal ring improves sealing effect simultaneously.
To achieve these goals, the technical solution of the utility model is as follows:
Valve body comprises body, it is characterized in that: being provided with inner end at body is that taper microcephaly outer end is the nipple orifice of straight hole, is provided with and main aperture parallel annular groove in the nipple orifice port on the inwall of described body.
Further, the both side ends up and down of described annular groove forms chamfered section.
Further, the degree of depth of described annular groove is greater than 0.5mm.
Further, the width of described annular groove is greater than nipple orifice taper microcephaly's diameter.
The beneficial effects of the utility model: the utility model is that taper microcephaly outer end is the nipple orifice of straight hole be provided with inner end at body, be provided with and main aperture parallel annular groove in the nipple orifice port on the inwall of described body, such structure, when spool moves up and down, the seal ring of spool end is because evagination, when moving to the nipple orifice place, because the setting of annular groove, the phenomenon of the asymmetric pressurized in the left and right sides just can not appear in seal ring, like this, when spool passed through nipple orifice, the seal ring on it just the phenomenon that is shifted can not occur, and has just avoided seal failure yet.
In order to prevent that seal ring from being scratched, in the formation of the both side ends up and down chamfered section of annular groove, seal ring slips into annular groove inside easily like this, also skids off annular groove easily, prolongs the working life of seal ring.
As from the foregoing, the utility model is simple in structure, and the protection seal ring improves sealing effect simultaneously.
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
Description of drawings
Fig. 1 is the structural representation in the utility model.
Embodiment
As shown in Figure 1, the utility model relates to a kind of valve body, comprise body 1, it is characterized in that: being provided with inner end at body 1 is that taper microcephaly 21 outer ends are the nipple orifice 2 of straight hole, is provided with and main aperture 11 parallel annular grooves 3 in nipple orifice 2 ports on the inwall of described body 1.
Further arrange, the both side ends up and down of described annular groove 3 forms chamfered section 4.
Further arrange, the degree of depth of described annular groove 3 is greater than 0.5mm.
Further arrange, the width of described annular groove 3 is greater than nipple orifice 2 taper microcephalies' 21 diameter.
The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
