Abstract
The utility model relates to a totally-enclosed mechanical valve handle confinement valve, comprising a valve body 10, a bonnet 1 and a valve handle8, wherein the valve handle8 is arranged with a handwheel9. The utility model is characterized in that the outside of the valve handle 8 between the bonnet 1 and the handwheel9 is arranged with a bonnet4 which is provided with a pressure sleeve2 and a sleeve pipe female screw6, wherein the pressure sleeve2 is arranged on the bonnet 1, the sleeve pipe female screw6 is sleeved with the outside of the valve handle 8 and is threadingly connected with the valve handle 8, the sleeve pipe female screw6 is arranged with a bearing5, the upper portion of the bearing 5 is arranged with a bearing stressed top7, the inner ring and the outer ring of the pressure sleeve2 are respectively arranged with seal rings3. The utility model has the advantages that the valve handle8 is totally enclosed in the bonnet4, the valve handle8 is uneasy to be corroded, and the valve handle8 is simultaneously sealed with only two zero-shaped seal rings3, thereby making the valve handle8 open more flexible and laborsaving, and achieving beautiful appearance and simple structure.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of valve that is applicable to a kind of totally-enclosed mechanical valve rod seal that uses on enterprise's production flow lines such as oil, chemical industry.
Background technique
Along with the fast development of industries such as oil, chemical industry, the consumption of pipeline valve also significantly increases, and simultaneously science, rationality, convenience and the economic serviceability of valve mechanism is also had higher requirement.The valve of conventional construction, from the valve gap to the handwheel between, be to take support to be connected mostly, the sealing between its valve rod and the valve gap is to fill up crack therebetween with filler, and then compresses the purpose that filler reaches sealing with Gland and bolt.The deficiency of this structure is: (1) valve rod is most of to be exposed outside, and corrosion is easily opened dumb; (2) must often change stuffing box packing, bring very big inconvenience to the user; (3) complex structure, the cost height.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes above-mentioned the deficiencies in the prior art, and a kind of valve of mechanical type full enclosed type valve rod is provided.
Technical solution of the present utility model is, comprise valve body, valve gap and valve rod, valve rod is provided with handwheel, it is characterized in that: the valve rod outside between valve gap and the handwheel is provided with bonnet, be provided with gland and sleeve pipe nut in the bonnet, gland places on the valve gap, and sleeve pipe nut is placed in the valve rod outside and connects with threaded stem, sleeve pipe nut is provided with bearing, and the upside of bearing is provided with bearing gland.
Bonnet and valve gap scyewed joint, bearing gland place in the bonnet and with the bonnet scyewed joint.
The gland inner ring is provided with two seal rings, and the gland outer ring is provided with three seal rings.
The advantage that the utility model is compared with prior art had is: valve rod is totally-enclosed in bonnet, make valve rod be difficult for corrosion, valve rod seals by two " O " RunddichtringOs simultaneously, thereby make valve rod open and become laborsaving more flexibly, and beautiful shape, simple in structure, processing, assembling have been saved great amount of manpower and material resources easily.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Number in the figure: 1-valve gap, 2-gland, 3-seal ring, 4-bonnet, 5-bearing, 6-sleeve pipe nut, 7-bearing gland, 8-valve rod, 9-handwheel, 10-valve body.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The utility model comprises valve body 10, valve gap 1 and valve rod 8, and valve rod 8 is provided with handwheel 9.Valve rod 8 outsides between valve gap 1 and the handwheel 9 are provided with bonnet 4.Be provided with a boss in the bonnet 4, the lower end of boss is provided with gland 2, and the upper end of boss is provided with sleeve pipe nut 6.Sleeve pipe nut 6 is placed in the outside of valve rod 8, and passes through scyewed joint with valve rod 8.Sleeve pipe nut 6 is provided with a shaft shoulder, and the shaft shoulder two sides are respectively equipped with bearing 5, and the upside of bearing 5 is provided with bearing gland 7, and bearing gland 7 places the inboard of bonnet 4 upper ends, and bearing gland 7 and bonnet 4 link by screw thread.
When rotating handwheel 9, by thread belt ovable valve stem 1 upstream or downstream on sleeve pipe nut 6 and the valve rod 1, two bearings 5 make handwheel 9 rotations more laborsaving at this.Seal by two seal rings 3 fully between valve rod 8 and the valve gap 1 in addition, so handwheel 9 is more laborsaving when rotating.
