Abstract
The invention relates to a valve, in particular to an out-of-control preventing wedge gate valve, which is characterized in that: an inner hole through bearing cover (11) is improved to an inner hole stepped bearing cover (11); and a step of the inner hole of the bearing cover (11) presses on an increased anti-penetration step of a valve rod nut (4). The bearing cover and the valve rod nut are improved, so that even if the valve rod nut on the valve is broken, a valve rod component cannot escape, and the ideal effects of preventing jet and preventing leakage are achieved; simultaneously, the valve rod nut of the valve can be continuously rotated to close a flashboard in an ideal state, so the valve does not influence the normal work of a whole pipeline, effectively ensures the safety of life and property of the people, and is very suitable to open and close high pressure pipelines of petroleum, chemical industry, power stations and the like.
Description
Technical field:
The present invention relates to a kind of valve, especially a kind of out-of-control preventing wedge gate valve.
Background technique:
In the process pipelines of all trades and professions, Wedge gate valve is owing to be clear opening, and its flow resistance is little, has and opens flexibly, and characteristics such as good seal performance are widely used, and Wedge gate valve only supplies standard-sized sheet, complete shut-down in whole pipeline, does not do throttling and uses.The transmission program of Wedge gate valve is: carry out mechanism driving by handwheel, handle or transmission device, transmission passes to valve rod by Stem Mut for Stem Mut (design code is a copper material) again, drives flashboard by valve rod and opens or close.By handwheel rotating band ovable valve stem nut rotation, the internal thread by Stem Mut passes to the valve rod outside thread, and valve rod is because the effect of guide mechanism forms rectilinear to-and-fro motion, the dextrorotation handwheel, and flashboard cuts out, left-handed handwheel, flashboard is opened, and whole passage connects.
(DN 〉=50mm PN 〉=14MPa) the copper Stem Mut of band rolling bearing use is analyzed according to market survey with to Wedge gate valve, the point of rupture of its fatigue damage has two places promptly in Stem Mut: 1. trapezoidal internal thread and endoporus junction, 2. shoulder supporting place of top rolling bearing.See " A-A " " B-B " two location in the accompanying drawing 1 for details, if use traditional endoporus straight-through type bearing gland, DN 〉=50mm PN 〉=14MPa Wedge gate valve is in use because of fatigue damage, in " A-A " zone or " B-B " zone, rupture and (normally could take place under the situation of closing, because of closing moment) greater than opening moment, then valve can't be closed, the unlatching of gate valve or close and just become out of control, at this moment valve rod and copper nut assembly can be scurried out to fully open position, so just influenced the proper functioning of whole pipeline, and, be easy to take place device security and life security incident with potential safety hazard.Sometimes can not normally close because of valve, cause pipeline and device damage, its economic loss is difficult to estimate.
Summary of the invention
The object of the present invention is to provide a kind of working life that prolongs this class gate valve, eliminate accident potential, guarantee Wedge gate valve can be in whole pipeline a kind of out-of-control preventing wedge gate valve of safe and reliable operation.
For achieving the above object, the technical solution adopted in the present invention is: out-of-control preventing wedge gate valve comprises valve body, valve gap, connect supporting sleeve, Stem Mut, bearing, handwheel, flat key, handwheel cover, valve rod, bearing gland, Cock screw, oil nozzle, flashboard, valve seat, inlet union, outlet connection is formed, it is characterized in that: with endoporus straight-through type bearing gland, be modified into endoporus step type bearing gland, the step of bearing gland endoporus is pressed in increase on the Stem Mut anti-and passes on the step.
Described a kind of out-of-control preventing wedge gate valve; it is characterized in that: between the endoporus of bearing gland and Stem Mut periphery, be furnished with the enhancing protecting jacket; the top that strengthens protecting jacket fits over increase on the Stem Mut anti-and passes above the step, and its underpart is crushed on below the step of bearing gland endoporus.
Described a kind of out-of-control preventing wedge gate valve is characterized in that: inlet union, outlet connection are made as one of structural type of flange plate or thimble connector.
The present invention's beneficial effect compared with prior art:
By the improvement to bearing gland, Stem Mut, the steel that increases strengthens protecting jacket again, even the Stem Mut fracture, valve rod assembly also can not be scurried out.Played the ideal effect of blowout prevention, anti-leak, simultaneously, this valve also can continue the rotary valve rod nut, flashboard cuts out reach perfect condition, thereby does not influence the proper functioning of whole pipeline, ensured the people's lives and property safety effectively.Be fit to very much do on the high-voltage tube roads such as oil, chemical industry, power station to open and close to use.
