Description
Technical field
The utility model relates to valve technology field, especially a kind of butterfly valve.
Background technique
In existing butterfly valve, its valve body is that left and right two video disc laminating is formed, and two video discs are connected by flange-type bolt.There is at the in-out end of valve body the tube head of plugging into extended outwardly, namely to have extended outwardly tube head of plugging at the phase dorsal part of two video discs of valve body, tube head of plugging into is adopted directly welding or is connected with external pipe by the accessory such as flange, clip, connect relative complex, inconvenience installation operation, user cost is high, is also inconvenient to safeguard.
Summary of the invention
The purpose of this utility model is the absence overcoming prior art, provides a kind of welding to connect butterfly valve fast, and assembling easily, is easy to safeguard, and assembles convenient and swift, good airproof performance.
For achieving the above object, the utility model adopts following technological scheme:
Welding connects butterfly valve fast, there is valve body and be mounted on the dish plate valve core in valve body, described valve body is made up of folder upper and lower two-part, extend outwardly at the two ends of valve body and be socketed the extension belled part of pipeline, the sleeve joint hole extended in belled part is communicated with dish plate valve core, and the inwall of sleeve joint hole is embedded with stuffing box gland.
The outer circumferential face of described extension belled part is provided with interlocking platform, and interlocking platform wears up and down for bolt, and attaching nut or screw interlocking, reach two-part up and down of valve body to clamping fixed.
Described interlocking platform constructs by extending belled part outer circumferential face local dent.
Described interlocking platform radially extends lobe configurations by extending belled part outer circumferential face.
Described stuffing box gland is the independent silica gel part arranged, or with coordinate the seal ring connecting body structure of dish plate seal spool in valve body.
Valve design is that upper and lower two-part are formed folder by the utility model, and the extension belled part of the socket pipeline that extends outwardly at the two ends of valve body, the sleeve joint hole extended in belled part is communicated with dish plate valve core, the inwall of sleeve joint hole is embedded with stuffing box gland, also can comply with when realizing valve body assembling thus and external pipe is clamped and connected, assemble convenient and swift, and have stuffing box gland to be tightly connected, good airproof performance.
The utility model again an advantage be that structure is simple, volume is little, lightweight, cost of investment is low, and cost performance is high, is applicable to the production and processings such as food, medicine, beverage and uses.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model one form structure schematic diagram;
Accompanying drawing 2 is one embodiment internal structure schematic diagram of the present utility model;
Accompanying drawing 3 is its two embodiments internal structure schematic diagram of the present utility model;
Accompanying drawing 4 is the utility model and external pipe connection diagram.
embodiment:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consult shown in Fig. 1,2,3,4, it is preferred embodiment schematic diagram of the present utility model, the utility model connects butterfly valve fast about a kind of welding, there is valve body 1 and be mounted on the dish plate valve core 2 in valve body, in valve body, also group is provided with the seal ring 5 coordinating dish plate valve core 2 to seal, sealing ring 5 seals face width, good airproof performance.Dish plate valve core 2 has the drive end 21 extended outside valve body, for connecting driving handle or automatic utensil, realizing thus driving dish plate valve core 2 to rotate outside, reaching butterfly switch work.Described valve body 1 is made up of folder upper and lower two-part, extend outwardly at the two ends of valve body 1 and be socketed the extension belled part 11 of pipeline, the sleeve joint hole 111 extended in belled part 11 is communicated with dish plate valve core 2, the inwall of sleeve joint hole 111 is embedded with stuffing box gland 3, sealing cover 3 be the silica gel part of independent setting, or with seal ring 5 connecting body structure coordinating dish plate valve core 2 to seal in valve body; Shown in Fig. 2, when stuffing box gland 3 is independently arranged, the inner and seal ring 5 respective end of stuffing box gland 3 are socketed, and form stacked sealing of plugging into; And shown in Fig. 3, stuffing box gland 3 and interior seal ring 5 connecting body structure coordinating dish plate valve core 2 to seal of valve body, then obtain integrated sealing, convenient making and assembling.As shown in Figure 4, external pipe 6 inserts in the sleeve joint hole 111 extended in belled part 11, determined and the friction sealed reinforcing of stuffing box gland 3 clamping by two-part up and down of valve body 1, also can comply with when realizing valve body assembling and external pipe is clamped and connected, assemble convenient, fast, welding and have stuffing box gland to be tightly connected, good airproof performance.
Shown in Fig. 1,4, in the present embodiment, the outer circumferential face of described extension belled part 11 is provided with interlocking platform 112, and interlocking platform 112 wears for bolt about 4, and attaching nut or screw interlocking, reach two-part up and down of valve body 1 to clamping fixed.Interlocking platform 112 can be constructed by extension belled part 11 outer circumferential face local dent, also can be radially extend lobe configurations by extension belled part 11 outer circumferential face.In the present embodiment, the extension belled part 11 at valve body 1 two ends all has bolt 4 interlocking to fix, and bolt 4 can be movable insertion and arranges, also can be bolt 4 is directly installed in extend in the upper part of belled part 11 or lower part, structure is simple, volume is little, lightweight, assembling easily, is easy to safeguard.
