Description
Technical field
The invention belongs to valve arrangement technical fields, and in particular to a kind of steam converter valve convenient for adjusting.
Background technique
With the further implementation of national energy conservation and emission reduction strategy, various press devices are grown rapidly, and are especially with steam
The large capacity large-sized unit press device of power source is quickly grown, wherein pressure reducing valve, especially using steam as the power station high temperature of medium
The purposes of high-pressure pressure-reducing valve is more and more wider.
Pressure reducing valve is inlet pressure to be reduced to the outlet pressure of a certain needs, and by the energy of medium itself by adjusting
Amount, makes outlet pressure automatically keep stable valve.From the viewpoint of hydrodynamics, pressure reducing valve is that a local resistance can become
The restricting element of change changes the kinetic energy of flow velocity and fluid, causes the different pressure losses that is, by change orifice size, from
And achieve the purpose that decompression.Then by the adjusting of control and regulating system, the fluctuation of downstream pressure is made to balance each other with spring force,
It keeps constant downstream pressure in certain error range, while spraying into cooling water in valve body or after valve, by the temperature of medium
Degree reduces.
Traditional pressure reducing valve is the structure of simple flap and valve rod, and valve rod connection flap simultaneously provides for the operation of flap
Hoisting capacity, but due to the effect of medium power, so that the closing forces pushed away under flap are larger, the opening force above opened is smaller, to lead
Cause fluctuation of service.In order to solve this problem, balance hole path is provided on flap to be connected to the space of flap segmentation, made
Certain media can balance medium power, reduce the hoisting capacity of flap by balance hole path flowing.But due to
The presence of hole path is balanced, so that medium can be flowed out by balance hole path, when not needing balance media power, medium still can be deposited
The case where revealing, the loss of pressure is caused.
Summary of the invention
Aiming at the problem that being mentioned in background technique, the purpose of the present invention is: it is intended to provide and a kind of subtracts convenient for the desuperheat of adjusting
Pressure valve, it can avoid the influence due to medium power to hoisting capacity, so that valve opening and closing is more convenient, while avoid pressure damage
It loses.
To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:

It states valve deck to be fixedly installed on valve body, executive device is installed on the valve deck, the valve body is equipped with air inlet and exhaust outlet,
The valve body includes uuper valve chamber and lower valve chamber, and the uuper valve chamber is connected to air inlet, lower valve chamber is connected to exhaust outlet, the upper valve
It is equipped with separation layer between chamber and lower valve chamber, on the separation layer is installed communicating pipe, offers first on the communicating pipe side wall
Connectivity slot is connected between the uuper valve chamber and lower valve chamber by the first connectivity slot, and the spool bottom end is equipped with flap, the valve
Valve includes flap column and fixed installation and the flap cylinder on flap column, and the flap cylinder side wall axially offers and the first connectivity slot
Matched second connectivity slot is equipped with limit plate between the valve body and valve deck, the spool is arranged in limit plate and spool
It is clearance fit between limit plate, the valve deck axially offers accommodating chamber, and the spool is in being equipped with adjusting in accommodating chamber
Tin, shape of threads sliding slot is offered inside the adjustment barrel, is slided in the adjustment barrel and is equipped with adjustment axis, outside the adjustment axis
On be fixedly installed with card column, the card column sliding is arranged in shape of threads sliding slot, and the valve deck top is equipped with sealing plate, the envelope
Plate is slidably located in adjustment axis, and the executive device is mounted on sealing plate, and the executive device and adjusting axis connection are used for band
Adjustment axis moves up and down.
In the technology of above-mentioned technical proposal, the present invention has also done following improvement:
It further limits, the range of the central angle of circular arc where first connectivity slot is 90 °~120 °, such structure
It designs, closed area angle is greater than the angle of the first connectivity slot on flap cylinder, and preferable first connectivity slot of flap cylinder is enable to carry out
Closing.
It further limits, the flap top end and limit plate bottom end offer mutual corresponding annular groove, the ring
Be equipped with the steel ball to match with annular groove in shape slot, such structure design, by steel ball by between flap column and limit plate by
Sliding friction becomes rolling friction, consequently facilitating the rotation of flap column.
Further limit, the separation layer in communicating pipe lower end it is concentric offer tapped blind hole, in the tapped blind hole
It is threaded with inner cylinder, the inner cylinder is ladder pipe structure, and the inner cylinder bottom end is screwed onto tapped blind hole, upper end is arranged in valve
In valve cylinder, for clearance fit and axial offer matches with the first connectivity slot between the upper end and flap cylinder of the inner cylinder
Third connecting slot, such structure design, protects valve body by inner cylinder, steam is direct when the first connectivity slot being avoided to open
Valve body is impacted, reduces valve body damage and extends valve service life.
It further limits, the valve body bottom end offers preformed hole, and the aperture size of the preformed hole is greater than tapped blind hole
Aperture size, the valve body bottom end is equipped with lower flange, and sealing ring, such structure are equipped between the lower flange and valve body
Design, directly can replace inner cylinder by preformed hole.
Further limit, be equipped with desuperheat water pipe in the lower flange, the desuperheat water pipe in closed at one end in valve body and
