Abstract
The invention discloses a method for manufacturing a soft sealing ring of a three-eccentric center soft sealing butterfly valve, which comprises the following steps of: (1) preparing a soft sealing ring on which a working allowance is reserved; (2) preparing a copying cutting clamp, wherein the shape of the cutting clamp is similar with that of the soft sealing ring which needs to be cut; (3) clamping the soft sealing ring on which the working allowance is reserved by the copying cutting clamp; and (4) cutting the soft sealing ring on which the working allowance is reserved along the copying cutting clamp. Due to the adoption of the method, the processing speed of the soft sealing ring of the three-eccentric center butterfly valve is greatly improved and the quality of the soft sealing ring with large size is also ensured.
Description
Technical field
The present invention relates to the production method of the soft seal circle of three eccentric soft sealing butterfly valves.
Background technique
Number of patent application be 201110237049.5 and the patent of 201120300548.X in put down in writing a kind of three eccentric soft sealing butterfly valves; The valve rod center line of this butterfly valve and sealing surface centerline axis are to off-centre; Constitute first off-centre, valve rod center line and valve channel longitudinal center line radial disbalance constitute second off-centre; Valve seat gyration center line and valve channel longitudinal center line angle are eccentric, constitute the 3rd off-centre; Because above-mentioned characteristic, its seal ring is non-symmetry structure as shown in Figure 1.The existing direct sulfuration of the normal employing of seal ring of making the type is processed through the mode of mould injecting glue; But for larger-size seal ring; Mould can't be realized too greatly because of size on technology or can't reach usage requirement; And its processing cost of seal ring through the mode of mould injecting glue is processed is higher, and Forming Quality is poor.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of production method of soft seal circle of three eccentric soft sealing butterfly valves in order to solve the deficiency of existing technology, enhances productivity, and guarantees quality of product
.
Technological scheme: in order to realize above purpose, the production method of the soft seal circle of three eccentric soft sealing butterfly valves of the present invention may further comprise the steps:
(1). prepare to leave the soft seal circle of machining allowance;
(2). prepare the profiling anchor clamps, the soft seal circle profile of this Cutting jip and required cutting is similar;
(3). the clamping of profiling anchor clamps leaves the soft seal circle of machining allowance;
(4). leave the soft seal circle of machining allowance along the cutting of profiling anchor clamps.
Further comprising the steps of: the soft seal circle to after the cutting completion carries out polishing treatment again.
Beneficial effect: the production method of the soft seal circle of three eccentric soft sealing butterfly valves provided by the invention, improved the processing speed of three eccentric butterfly valve soft seal circle greatly, guaranteed the quality of larger-size soft seal circle simultaneously.
Description of drawings
Fig. 1 is the seal ring sectional drawing of three eccentric soft sealing butterfly valves.
Fig. 2 is the profiling phase diagram.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
The production method of the soft seal circle of three eccentric soft sealing butterfly valves of the present invention may further comprise the steps:
(1). prepare to leave the soft seal circle of machining allowance; As shown in Figure 1, the soft seal circle of three eccentric soft sealing butterfly valves adopts nonmetallic material to process, and is preferably rubber; It is non-symmetry structure; When preparation leaves the soft seal circle of machining allowance, at first prepare the long strip raw material, carry out building up by welding by certain-length then; At last that its ending is gluing, thus acquisition leaves the soft seal circle of surplus.
(2). prepare the profiling anchor clamps, the soft seal circle profile of this Cutting jip and required cutting is similar, and size is slightly larger than the structure of the dish plate and the fastening soft seal circle that retainer constitutes of three eccentric soft sealing butterfly valves.
(3). the clamping of profiling anchor clamps leaves the soft seal circle of machining allowance;
(4). leave the soft seal circle of machining allowance along the cutting of profiling anchor clamps.As shown in Figure 2, along profiling anchor clamps periphery the soft seal circle that leaves machining allowance is carried out cutting operation with milling cutter 3, with its surplus excision, make that the cross-section structure that cuts the soft seal circle after accomplishing is consistent with the cutting face of profiling anchor clamps.
After cutting was accomplished, the soft seal circle after can also accomplishing cutting carried out polishing treatment again, makes its cutting face more smooth, improves sealing effect.
Technical conceive of the present invention and characteristics its objective is to let and are familiar with these those skilled in the art and can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
Claims (2)
1. the production method of the soft seal circle of three eccentric soft sealing butterfly valves is characterized in that, may further comprise the steps:
(1). prepare to leave the soft seal circle of machining allowance;
(2). prepare the profiling anchor clamps, the soft seal circle profile of this Cutting jip and required cutting is similar;
(3). the clamping of profiling anchor clamps leaves the soft seal circle of machining allowance;
(4). leave the soft seal circle of machining allowance along the cutting of profiling anchor clamps.
2. the production method of the soft seal circle of three eccentric soft sealing butterfly valves according to claim 1 is characterized in that, and is further comprising the steps of: the soft seal circle after cutting is accomplished carries out polishing treatment again.
