Abstract
The utility model discloses a valve rod sealing mechanism of a valve, which comprises a valve rod (1), a valve body (5) and a packing gland (6). The valve body (5) is provided with a through hole for the valve rod to pass through. The end part of the through hole is provided with padding (3). The valve rod sealing mechanism of the valve is characterized in that the end part of the through hole is provided with a pressing ring (2); a spring (7) is sleeved on the valve rod (1); one end of the spring (7) is in contact with the pressing ring (2), and the other end of the spring (7) is in contact with the packing gland (6); and the end part of the through hole is sealed by the pressing ring (2). The valve rod sealing mechanism of the valve can be used for automatically regulating the padding when the padding is loosened, and has the advantages of convenience and safety.
Description
Technical field
The utility model relates to a kind of valve, and what be specifically related to is a kind of valve stem seal mechanism of valve.
Background technique
At present, the structure of valve all has valve rod and valve body, and its valve rod passes the through hole of valve body, these valves are used for opening or closing of liquid or gas, and the contacting point of its valve rod and valve hole all seals with filler, are provided with gland in the end of through hole, gland uses bolton on valve body, in long-term use, filler is worn, and just can cause gas leakage or leakage, at this moment want running check, if any the filler wearing and tearing, just to tight a bolt once more, filler is compressed its sealing.The valve stem seal mechanism of this structure, owing to will often check valve, and want often the degree that compresses of gland and filler to be regulated, very inconvenience, simultaneously, if inspection has carelessness slightly or neglects, just can cause the leakage of liquid or gas, very dangerous.
Summary of the invention
In view of the deficiency that background technique exists, the technical problems to be solved in the utility model provides a kind of valve stem seal mechanism that automatically filler is compressed the valve that degree regulates.
For this reason, the utility model adopts following technological scheme to realize: a kind of valve stem seal mechanism of valve, comprise valve rod, valve body and Gland, described valve body is provided with the through hole that passes for described valve rod, and the end of described through hole is provided with filler, it is characterized in that being provided with trim ring in the end of described through hole, be with spring on the described valve rod, one end of described spring contacts with described trim ring, and the other end contacts with described Gland, and described trim ring is sealed the end of described through hole; Described Gland is fixed by bolts on the described valve body.
This structure of the present utility model, the spring on its valve rod according to the degree of wear of filler, because himself elastic force can withstand trim ring automatically, compresses filler, needn't often check and regulate, and has safety and characteristics easily.
Description of drawings
Further describe relevant details of the present utility model below more in conjunction with the accompanying drawings.
Fig. 1 is the structural drawing of the utility model background technique;
Fig. 2 is a structural drawing of the present utility model.
Embodiment
With reference to accompanying drawing 2, the valve stem seal mechanism of this valve, comprise valve rod 1, valve body 5 and Gland 6, described valve body 5 is provided with the through hole (not marking among the figure) that passes for described valve rod 1, and the end of described through hole is provided with filler 3, is provided with trim ring 2 in the end of described through hole, be with spring 7 on the described valve rod 1, one end of described spring 7 contacts with described trim ring 2, and the other end contacts with described Gland 6, and described trim ring 2 is sealed the end of described through hole; Described gland 6 usefulness bolts 4 are fixed on the described valve body 5, during installation, after placing filler 3 in the through hole, push down with trim ring 2, cover upper spring 7 on valve rod 1 in that Gland 6 is enclosed within on the valve rod 1, is fixed with bolt 4 again, during with bolt 4 stationary gland 6, spring 7 has suitable compression degree and is advisable.When valve rod 1 often moves, filler 3 just can wear and tear loosening, the elastic force that have by compression owing to spring 7 this moment, can automatically trim ring 2 be pressed toward filler 3, keep the degree that compresses of filler 3, make to keep sealing forever, needn't often regulate bolt 4, have characteristics convenient and safety.This structure of the present utility model can be used for the sealing of pump rotatingshaft, because same because the frequent rotation of rotatingshaft causes the leakage of oil of the pump housing, also can seal equally with this structure.
Claims (2)
1. the valve stem seal mechanism of a valve, comprise valve rod (1), valve body (5) and Gland (6), described valve body (5) is provided with the through hole that passes for described valve rod, the end of described through hole is provided with filler (3), it is characterized in that being provided with trim ring (2) in the end of described through hole, be with spring (7) on the described valve rod (1), one end of described spring (7) contacts with described trim ring (2), the other end contacts with described Gland (6), the end that described trim ring (2) is sealed described through hole.
2. the valve stem seal mechanism of valve according to claim 1 is characterized in that described Gland (6) is fixed on the described valve body (5) with bolt (4).
