Abstract
The utility model discloses a novel sealing gate valve, which comprises a valve body (7) and a valve rod (9). Filler (8) is arranged between the valve rod (7) and the valve rod (9) for sealing, and a gland bush (1) is arranged on the filler (8) to position the filler (8). The novel sealing gate valve is characterized in that an H-shaped sealing ring (6) with an H-shaped section is also arranged in the middle of the filler (8), a plurality of small holes (5) are arranged at the middle part of the H-shaped sealing ring (6), the valve body (7) which corresponds to the H-shaped sealing ring (6) is provided with a plurality of oil holes (10), and oil nipples (4) for sealing the oil holes are arranged on the oil holes (10). The utility model has long use time and good sealing effect and greatly reduces the cost of a factory.
Description
Technical field
The utility model relates to a kind of gate valve, especially a kind of seal arrangement of gate valve.
Background technique
Gate valve is a kind of ducted standard equipment such as plumbing, food, medicine, industrial and mineral, chemical industry, gas delivery that are widely used in.Gate valve more and more is subjected to the favor in market because of advantages such as its volume are little, in light weight, opening and closing time is short, and the weight key of valve is sealing, and the effect key of sealing depends on the quality of seal form.The structure of gate valve mainly is made up of valve body and valve rod.Between valve body and valve rod, be respectively equipped with the filler that is used for sealing, reach the effect of sealing.The shortcoming of this sealing is: because mostly filler is the oiliness packing, it is volatile, dry, gate valve rotation valve rod in use often makes dry filler fragmentation, and then make gate valve very easily cause seal failure, can only reach effective seal by frequent replacing filler like this, because it is big to change the labor intensity of filler, make when gate valve uses, maintain more difficult.
The model utility content
The purpose of this utility model solves existing gate valve exactly because of sealing flimsy problem, and a kind of gate valve of novel seal is provided.
The technical solution adopted in the utility model is: the novel seal gate valve, it comprises valve body and valve rod, being provided with filler between valve body and the valve rod seals, filler is provided with gland filler is positioned, it is characterized in that it is I-shaped I-shaped seal ring that described filler centre also is provided with the cross section, I-shaped seal ring middle part is provided with several apertures, and the valve body of I-shaped seal ring correspondence is provided with several oilholes, and oilhole is provided with and is used for oil nozzle that oilhole is sealed.
Adopt technique scheme, when gate valve is regularly opened oil nozzle in use, in oilhole, inject lubricant oil, lubricant oil enters the inboard by the middle part aperture of I-shaped seal ring, along making filler obtain soaking between valve rod and the filler gradually, thereby can not make filler become dry, therefore can guarantee the long-time use of filler, thereby make that maintenance is more convenient.
In sum, the beneficial effects of the utility model are: owing to the utility model passes through regularly to inject lubricant oil to filler, thereby can guarantee the sealing of gate valve, maintain easily maintenance, therefore reduce factory cost.

Embodiment
The utility model novel seal gate valve, as shown in Figure 1, it comprises valve body 7 and valve rod 9, being provided with filler 8 between valve body 7 and the valve rod 9 seals, filler 8 is provided with 1 pair of filler 8 of gland and positions, gland 1 is between filler 8 and valve gap 2, and valve gap 2 connects by several bolts 3 with valve body 7, makes gland 1 push the firmly upper end of filler 8 all the time.Being provided with the cross section in the middle of the filler 8 is I-shaped I-shaped seal ring 6, and I-shaped seal ring 6 middle parts are provided with several apertures 5, and the valve body 7 of I-shaped seal ring 6 correspondences is provided with several oilholes 10, and oilhole 10 is provided with and is used for oil nozzle 4 that oilhole is sealed.
