Abstract
The utility model discloses a low and medium pressure valve mid-head sealing. The structure comprises a valve body, a tooth type gasket and a valve cover, wherein the tooth type gasket is arranged between the valve body and the valve cover, closed pattern teeth are correspondingly arranged on the valve body and the valve cover, original closed pattern grooves in the valve body and the valve cover are changed into planes, and the processing difficulty and the processing cost are lowered; the whole tooth type gasket is round, teeth arranged on the tooth type gasket are correspondingly meshed with the closed pattern teeth, the manufacturing is simple, the maintenance is convenient, and the sealing is reliable. The closed pattern grooves are changed into the planes, the sealing gaskets are designed, so that the raw material cost is reduced, the processing difficulty is lowered, and the maintenance is convenient.
Description
Technical field
The utility model relates to a kind of sealing configuration, relates in particular to a kind ofly for head sealing in the mesolow valve of mesolow valve, belongs to valve field.
Background technique
In petroleum machinery mesolow valve, the sealing of valve body and valve gap generally adopts metal o-ring sealing at present, conventional method is on valve body and valve gap, to process concentric groove groove, metal o-ring is put in valve body concentric groove groove, by the prefastening force of bolt, make the concentric groove tooth pressure of valve body and valve gap enter the effect that reaches sealing in metal o-ring; It is larger that such structure is processed concentric groove groove difficulty on valve body and valve gap, once damaging appears in the concentric groove groove on valve body and valve gap, is difficult to repair, and can only scrap.
Summary of the invention
In order to solve problems of the prior art and deficiency, the utility model provides head sealing in a kind of mesolow valve, by architecture advances, can reduce cost of material, reduces difficulty of processing, can maintain easily simultaneously.
The purpose of this utility model realizes by the following technical solutions.
Head sealing in mesolow valve, comprises in structure: valve body, and dentiform gasket, valve gap, dentiform gasket is arranged at valve body and valve cover chamber, valve body and the corresponding concentric groove tooth that is provided with on valve gap.
Described valve body and valve gap, original concentric groove groove is revised as plane by it, reduces difficulty of processing and processing cost.
Described dentiform gasket, entirety is circular, is provided with the tooth of engagement corresponding to concentric groove tooth on it, makes simply, easy to maintenance, sealing is reliable.
The utility model is revised as plane by concentric groove groove and to sealing gasket design, can reduces the cost of raw material, reduce difficulty of processing, maintains easily.
Brief description of the drawings
Fig. 1 is the utility model one example structure schematic diagram
Fig. 2 is the structural representation of the utility model sealing gasket.
In figure: 1 valve body, 2 dentiform gaskets, 3 valve gaps, 21 teeth.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described
Embodiment as shown in Figure 1 and Figure 2, head sealing in mesolow valve, comprises in structure: valve body, dentiform gasket, valve gap, dentiform gasket is arranged at valve body and valve cover chamber, valve body and the corresponding concentric groove tooth that is provided with on valve gap.
Further, described valve body and valve gap, original concentric groove groove is revised as plane by it, reduces difficulty of processing and processing cost.
Further, described dentiform gasket, entirety is circular, is provided with the tooth of engagement corresponding to concentric groove tooth on it, makes simply, easy to maintenance, sealing is reliable.
The utility model is revised as plane by concentric groove groove and to sealing gasket design, can reduces the cost of raw material, reduce difficulty of processing, maintains easily.
Above embodiment is only in order to the utility model non-limiting the utility model to be described, any to amendment of the present utility model or within replacing and being all encompassed in claim of the present utility model.
