Abstract
The utility model provides a cone-shaped tunnel gate valve comprising a valve body with a guiding rib, a fluid inlet tunnel and a fluid outlet tunnel, a valve cover, a material charging chamber, a sealing filler, a filler gland, a flashboard, a valve rod and a hand wheel. The key of the cone-shaped tunnel gate valve is that the material charging chamber is directly arranged in a cover body on the top of the valve cover; the inner wall of the material charging chamber is provided with a baffle ring groove; the bottom of the material charging chamber under the baffle ring groove is further provided with a check ring; the valve rod is coupled with the check ring via a groove on the valve rod; the baffle ring is embedded into the baffle ring groove and fastens the baffle ring groove in an axial direction; the filler gland is directly coupled with the valve cover via a bolt to compress tightly the filler; and both the fluid inlet and outlet tunnels are cone-shaped tunnels with an inner end diameter and an outer end diameter larger than the inner end diameter. Metal or non-metal anticorrosion pads are arranged on seal surfaces between the flashboard and the fluid inlet tunnel and between the flashboard and the fluid outlet tunnel. The fluid inlet and outlet tunnels of the gate valve are changed from the cylindrical tunnels to the cone-shaped tunnels with relative small inner end diameter and relative large outer end diameter, so that the diameter of the flashboard and the volume of the inner cavity of the valve body are reduced.
Description
Technical field
The utility model belongs to valve and manufactures field, particularly relates to a kind of cone-shape duct gate valve.
Background technique
Conventional gate valve is due to fluid, to be cylindrical (straight-through type) duct into and out of hole, corresponding flashboard and body cavity size are large, material expend many and use in required moment also larger; Owing between valve gap and Gland, establishing a filler microcephaly independently, in order to axial restraint valve rod and filling stuffing box packing, both there is complex structure, its sealing is poor again.Therefore, above-mentioned gate valve exist structure and processing technology than complicated, volume than large, consumptive material is many, sealing is poor and the more high disadvantage of cost of production.
Summary of the invention
The purpose of this utility model is the defect existed for background technique, improves design a kind of cone-shape duct gate valve, simplifies structure and processing technology to reach, and reduces consumptive material and valve weight and cost of production, improves sealing, reduces the purposes such as valve volume.
Solution of the present utility model is that the filler microcephaly is saved, and on lid top, directly set up one for the sealing filler chamber, and by "T"-shaped cancellation of the T-shape axle on traditional gate valve, and coordinate stop ring to replace its function with back-up ring, to the valve rod axially locating; Into and out of hole, change the fluid of gate valve into inner diameter by cylindrical bore simultaneously less, and the larger cone-shape duct of outer end diameter, and the corresponding diameter of flashboard and the volume of body cavity of reducing, thereby realize its purpose.Therefore, the utility model comprises tape guide rib and the fluid valve body into and out of duct, valve gap, filler chamber and stuffing box packing thereof, Gland, flashboard, valve rod and handwheel; Key is that filler chamber directly is located in valve upper part of the cover lid, on the inwall of filler chamber, also be provided with a circlip groove, the following filler chamber bottom of circlip groove also is provided with a stop ring, and valve rod connects back-up ring and is embedded in circlip groove its axial restraint with stop ring by the groove on it; Gland directly connects to compress filler by bolt with valve gap; Fluid is the cone-shape duct that inner diameter is little than the outer end diameter into and out of duct.In order to be applicable to the aggressive medium pipe network system, also be provided with metal or nonmetal anticorrosion pad on flashboard and sealing surface that fluid coordinates into and out of duct.
The utility model is due to filler chamber directly is located in valve gap, and coordinates so that valve rod is made to axial restraint by back-up ring and stop ring, thereby saved the filler microcephaly, simplifies the structure and improved sealing; To change into and out of the duct of fluid and be made as the cone-shape hole, and can make again the consumptive material of same specification valve reduce by 5～25%, the keying moment in its use also can reduce 5～20%.Therefore, the utlity model has simple in structure, reliable, good airproof performance, the characteristics such as volume is little, lightweight, and cost of production is lower.
The accompanying drawing explanation
Fig. 1, Fig. 2, be the utility model structural representation.
In Fig. 1: 1-valve body, 2-fluid enter (going out) duct, 3-flashboard, 4-lower valve rod nut, 5-valve gap, 6-stop ring, 7-back-up ring, 8-filler, 9-handwheel, 10-Gland, 11-Packing seat, 12-valve rod, 13, the anticorrosion pad of 14-.
Embodiment
Below in conjunction with Figure of description, further illustrate.
The utility model cone-shape duct gate valve comprises that tape guide rib and fluid advance the valve body 1 in (going out) duct 2, valve gap 5, filler chamber and stuffing box packing 8 thereof, Gland 10, flashboard 3, valve rod 12 and handwheel 9; It is characterized in that filler chamber directly is located in the lid on valve gap 5 tops, on the inwall of filler chamber, also be provided with a circlip groove, the following filler chamber bottom of circlip groove also is provided with a stop ring 6, and valve rod 12 connects back-up ring 7 and is embedded in circlip groove its axial restraint with stop ring 6 by the groove on it; 10 of Glands directly connect to compress filler with valve gap 5 by bolt; Fluid 2 is the cone-shape duct that inner diameter is little than the outer end diameter into and out of duct.In order to be applicable to the aggressive medium pipe network system, also be provided with metal or nonmetal anticorrosion pad 13,14 on flashboard and sealing surface that fluid coordinates into and out of duct.By cylindrical bore, to change inner diameter into less because the fluid by gate valve enters (going out) duct 2, and the larger cone-shape duct of outer end diameter, and the corresponding diameter of flashboard 3 and the volume of body cavity of reducing.
