Abstract
The utility model relates to the technical field of valves, in particular to a novel pressure balanced plug valve, which is characterized by comprising a valve body, a steel ball, a seal ring, a plug body, a tapered sleeve, a pressure pad, a filler, an upper cover, a filler gland and a handle. The plug body in a cylindrical shape is provided with the seal ring and is matched with the valve body through fixation of the tapered sleeve, and the seal ring of the cylindrical plug body adopts a soft seal. Since the metal plug body and the valve body are directly contacted for sealing, and the soft seal type seal ring can reinforce sealing, the utility model achieves the dual sealing effect. Moreover, the plug body can not be worn, thereby improving the sealing performance and preventing leakage.
Description
Technical field
The utility model relates to valve technology field, especially a kind of novel pressure balanced plug valve.
Background technique
Stopcock is to use a kind of valve the earliest, and is simple in structure, switch is rapid, fluid resistance is little.Common stopcock seals with direct contact the between valve body by accurately machined metal cock body, so sealing is relatively poor, hoisting capacity is big, easily to the cock body wearing and tearing, produces and leaks, and therefore needs often to change the cock body part, thereby has improved maintenance cost.
Summary of the invention
A kind of novel pressure balanced plug valve, its feature, comprise: valve body 1, steel ball 2, seal ring 3, cock body 4, tapered sleeve 5, pressure pad 6, filler 7, loam cake 8, Gland 9, handle 13, the cock body 4 of described a kind of novel pressure balanced plug valve is the cylindrical body form, be provided with seal ring 3, with fixing by tapered sleeve 5 between valve body 1 cooperates, the seal ring 3 of the cock body 4 of described cylindrical body form is soft seal, can wearing and tearing not arranged to cock body, therefore need not often change cock body 4 component, save maintenance cost greatly.A kind of novel pressure balanced plug valve, not only directly contact seal of metal cock body and valve body itself, and seal ring 3 enhanced leaktightness by soft seal have the double seal effect, can itself not produce cock body 4 and wear and tear, and improve the sealability height, can not leak.
The beneficial effects of the utility model: 1. cock body 4 rotates with handle 13 and realizes switching motion, and cock body is cylindrical body, relies on seal ring 3 to reach effective seal action, can not produce leakage, can not wear and tear to cock body, and good sealing effect is cut the saving maintenance cost.2. eliminated thermal expansion problem, need not heat release and valve body and release automatically.3. improve working efficiency, reduced parts loss and maintenance cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of novel pressure balanced plug valve, described cock body 4 is cylindrical body forms, be provided with seal ring 3 in cock body 4 bottoms, and fixing between the valve body 1 by tapered sleeve 5, the seal ring 3 of cock body 4 is soft seals, cock body 4 rotates with handle 13 and realizes switching motion, cock body is cylindrical body, relies on seal ring 3 to reach effective seal action, can not produce leakage, can not wear and tear to cock body, good sealing effect is cut the saving maintenance cost.
Claims (2)
1. novel pressure balanced plug valve, it is characterized in that, comprising: valve body, steel ball, seal ring, cock body, tapered sleeve, pressure pad, filler, loam cake, Gland, handle, described cock body are the cylindrical body forms, be provided with seal ring, and fix by tapered sleeve between the valve body.
2. a kind of novel pressure balanced plug valve as claimed in claim 1, the seal ring that it is characterized in that described cock body is soft seal.
