Description
Technical field:
The utility model relates to a kind of novel bracing type ball valve, belongs to valve technology field.
Background technique:
At present, in industrial piping system, often need use gate valve and track ball valve.
The gate valve fluid resistance is little, and switching station needs external force less, and flowing to of medium is unrestricted, and during standard-sized sheet, sealing surface is subjected to the erosion of working medium littler than stop valve, and the bodily form is fairly simple, and casting manufacturability is better.But gate valve has following deficiency simultaneously: 1, boundary dimension and Lift are all bigger, and installation footprint is bigger; 2, in the switching process, relative friction is arranged between sealing surface, cause the scratch phenomenon easily; 3, gate valve generally has two sealing surfaces, gives processing, grinds and some difficulties of maintenance increase.
The spheroid of track ball valve is a whole ball, can realize the metal sealing, and is high temperature resistant, but it also has following deficiency: 1, one-way sealing flows to requirement; 2, guiding groove is installed on the valve rod, and guide finger is rack-mount, and friction between the two is sliding friction, and frictional force is bigger; 3, sealing should not be designed, filler can not be under valve band pressure situation, increased or change; 4, under the valve closing state, can not clean inner chamber.
In sum, existing gate valve or track ball valve have been difficult to satisfy the fast-developing needs of industry, are badly in need of a kind of plurality of advantages that comprises existing gate valve and track ball valve, abandon the valve of its shortcoming.
The model utility content:
At the problems referred to above, the technical problems to be solved in the utility model provides a kind of novel bracing type ball valve.
Bracing type ball valve of the present utility model, it comprises valve body, lower valve rod, following base ring, last base ring, the sphere flap, the wedge-type cone, valve rod, middle cover, lining, Packing seat, filler, Gland, support, guide finger, roller, check ring and man-operated mechanism, the valve body inner bottom part is provided with lower valve rod, the arranged outside of lower valve rod has following base ring and last base ring, and last base ring is fixed on down the base ring upper end by socket head screw, be provided with two sphere flaps that have the inclined-plane in the upper end of last base ring, be movably set with the wedge-type cone by T-slot between the sphere flap that two have an inclined-plane, fixedly connected by screw thread and straight pin with the lower end of valve rod in the upper end of wedge-type cone, fixedly there is middle cover at the middle part of valve body by double-screw bolt, and the joint of middle cover and valve rod is provided with lining, the arranged outside of lining has Packing seat, Packing seat is provided with filler, the upper end of filler is provided with Gland, support is fixed on the middle cover upper end by double-screw bolt, the valve rod on support top is provided with guide finger, the two ends of guide finger are provided with two rollers, the outside at two rollers respectively is provided with a check ring, and the top of valve rod is connected with man-operated mechanism by trapezoidal thread.
As preferably, the above and below of described sphere flap is respectively arranged with limited ring and spacer, makes it not rise or to descend with the wedge-type cone, can only do translation with the wedge-type cone in a horizontal space or rotatablely moves.
The beneficial effects of the utility model: it combines the advantage of gate valve and track ball valve, has abandoned the shortcoming of the two, and sealing surface does not have friction, corrosion-resistant, stroke is short, and opening speed is fast, installing space is little, two way sealed, and nothing flows to requirement, guide finger is rolling friction in guiding groove, frictional force is little, can design sealing, can increase or change filler under valve band pressure situation, and under the situation of valve closing, also can purge its inner chamber, easy to use.
Description of drawings:
In order to be easy to explanation, the utility model is done to describe in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation.
The 1-valve body; The 2-lower valve rod; Base ring under the 3-; The last base ring of 4-; 5-sphere flap; 6-wedge-type cone; The 7-valve rod; The 8-middle cover; The 9-lining; The 10-Packing seat; The 11-filler; The 12-Gland; The 13-support; The 14-guide finger; The 15-roller; The 16-check ring; The 17-man-operated mechanism.
Embodiment:
As shown in Figure 1, this embodiment is by the following technical solutions: it comprises valve body 1, lower valve rod 2, following base ring 3, last base ring 4, sphere flap 5, wedge-type cone 6, valve rod 7, middle cover 8, lining 9, Packing seat 10, filler 11, Gland 12, support 13, guide finger 14, roller 15, check ring 16 and man-operated mechanism 17, valve body 1 inner bottom part is provided with lower valve rod 2, the arranged outside of lower valve rod 2 has following base ring 3 and last base ring 4, and last base ring 4 is fixed on down base ring 3 upper ends by socket head screw, be provided with two sphere flaps 5 that have the inclined-plane in the upper end of last base ring 4, be movably set with wedge-type cone 6 by T-slot between the sphere flap 5 that two have an inclined-plane, fixedly connected by screw thread and straight pin in the lower end of the upper end of wedge-type cone 6 and valve rod 7, fixedly there is middle cover 8 at the middle part of valve body 1 by double-screw bolt, and middle cover 8 is provided with lining 9 with the joint of valve rod 7, the arranged outside of lining 9 has Packing seat 10, Packing seat 10 is provided with filler 11, the upper end of filler 11 is provided with Gland 12, support 13 is fixed on middle cover 8 upper ends by double-screw bolt, the valve rod 7 on support 13 tops is provided with guide finger 14, the two ends of guide finger 14 are provided with two rollers 15, respectively be provided with a check ring 16 in the outside of two rollers 15, the top of valve rod 7 is connected with man-operated mechanism 17 by trapezoidal thread.
