Description

Critical gate gurgle valve
Technical field
The present invention relates to a kind of critical gate gurgle valve, belong to steam turbine equipment field.
Background technology
Security personnel's oil circuit of steam turbine, as the term suggests it is to ensure that safe oil circuit.It is to support automatically when normally running The unlatching of closer, when running into protection act, security personnel's oil cuts off steam turbine into vapour to protect steam turbine failure not by pressure release Expand again.
The content of the invention
Present invention aims at a kind of critical gate gurgle valve is provided, in the quick draining of clutch, so as to quickly release guarantor Pacify oil pressure, main inlet throttle-stop valve and extraction valve is faster closed, be not to damage because Steam Turbine Over-speed Accident is excessive.
To solve the above problems, the present invention provides a kind of critical gate gurgle valve, it is characterised in that valve body one end is equipped with valve deck, Valve rod passes through valve deck, and valve rod is fixedly connected with being arranged on the valve head of valve inner, and the part that the valve rod is located in valve body is cased with Elastic component;Valve outer surface is equipped with oil leak hole, and oil leak hole is fully sealed in the valve head;Body base is equipped with security personnel's oil-in chamber, institute State security personnel's oil-in chamber bottom and be equipped with security personnel's oilhole;Valve stem top is equipped with handwheel.
Preferably, it is equipped with baffle between the valve rod and valve head, the valve rod, valve head, baffle are suitable according to from top to bottom Sequence is bolted to connection.Valve rod, valve head, baffle can move up and down at the same time.
Preferably, the elastic component is spring.Valve rod is set to move down opening draining rapidly with valve head using elastic force.
Preferably, the both ends of the spring is fixed between baffle and valve deck.
Preferably, valve rod is connected with handwheel by hand wheel nut.It is convenient to recover to lift valve rod and valve head during security personnel's oil pressure.
Preferably, the valve head side is equipped with sealing plate, and the sealing plate can seal oil leak hole.Sealing plate can be with valve head Slide up and down, oil leak hole is sealed.
Beneficial effect of the present invention:
The present invention can make when security personnel's oil reduces to a certain extent, and valve rod and valve head are fast under the action of upper springs power Speed moves down, and opens draining, faster releases security personnel's oil pressure in clutch, main inlet throttle-stop valve and extraction valve is faster closed, It is not Steam Turbine Over-speed Accident excessive and damages.Want to recover security personnel's oil pressure at the same time, it is necessary to which pulling top handwheel closing draining can just build Vertical security personnel's oil pressure, which prevent open main inlet throttle-stop valve and extraction valve causes the accident because maloperation rises security personnel's oil pressure.

Embodiment
Embodiment 1:
With reference to Figure of description, the present invention provides a kind of critical gate gurgle valve, it is characterised in that 10 one end of valve body is equipped with valve deck 12, valve rod 2 passes through valve deck 12, and valve rod 2 is connected with the baffle 9 being arranged on inside valve body 10, and baffle 9 is connected with valve head 3, valve rod 2, Baffle 9, valve head 3 are bolted to connection according to order from top to bottom.Valve rod 2 is cased with spring 7, and 7 both ends of spring are fixed on Between baffle 9 and valve deck 12.10 outer surface of valve body is equipped with oil leak hole 6, and 3 side of valve head is equipped with sealing plate 5, and sealing plate 5 can be complete Hermetically sealed oil leak hole 6;10 bottom of valve body is equipped with security personnel's oil-in chamber 4, and 4 bottom of security personnel's oil-in chamber is equipped with security personnel's oilhole 8, security personnel Oilhole 8 is used for oily inflow and outflow of ensuring public security, and the top of valve rod 2 is equipped with handwheel 1, valve rod 2 and handwheel 1 and passes through the fixation of hand wheel nut 11 company Connect.
The present invention is installed on security personnel's oil circuit of steam turbine, and operation principle is:When oil pressure of ensuring public security is normal, oil pressure of ensuring public security Equal with the elastic force of spring 7, the sealing plate 5 on valve head 3 seals oil leak hole 6, and oil reduction is ensured public security to a certain extent in clutch When, oil pressure reduces, and valve rod 2 moves down rapidly with valve head 3 under the action of 7 spring force of spring, drives sealing plate 5 to move down rapidly, beats Oil leak hole 6 is opened, so that quick draining, makes main inlet throttle-stop valve and extraction valve faster close, it is excessive and damage to be not Steam Turbine Over-speed Accident It is bad.To recover oil pressure of ensuring public security, the oil pressure for oil of ensuring public security changes from small to big in recovery process, due to oil leakage of ensuring public security before, security personnel Pressure reduces in oil-in chamber 4, and less than the elastic force of spring 7, valve head 3 and valve rod 2 are subject to the downward elastic force of spring 7, can not establish guarantor Pacify oil pressure, it is therefore necessary to pull top handwheel 1 and offset elastic force closing draining, recover security personnel's oil, then recover security personnel's oil pressure Security personnel's oil pressure could be established to the state equal with elastic force, which prevent open main vapour because maloperation rises security personnel's oil pressure Door and extraction valve cause the accident.
The foregoing is merely the embodiment of the present invention, is not intended to limit the scope of the invention, every to utilize this hair The equivalent structure or equivalent flow shift that bright specification and accompanying drawing content are made, is directly or indirectly used in other relevant skills Art field, is included within the scope of the present invention.
