Abstract

The present invention relates to a kind of abrasive suspension reduction valve, it is made up of valve box, gate throttle, nozzle needle and nozzle needle bearing.The valve box is made of spherical housing, and cylindrical throttle valve body adjoins with it, and nozzle needle is bearing in the spherical housing, and it can move along the direction of gate throttle, and stretch out from spherical housing on the top of nozzle needle, and inserts in the throttle valve body.Reduction valve long service life of the present invention, easy to maintenance.

Description

Reduction valve
The present invention relates to a kind of abrasive suspension reduction valve, it is made up of a valve box, gate throttle, nozzle needle and nozzle needle bearing.
This class also is called the reduction valve of " adjustable nozzle " in mechanical manufacturing engineering, known have diversified structural type.Often utilize it that steam flow is throttled to predetermined size, vapor pressure is then controlled by valve rod on conical wing valve and film.Even this device is used for regulating relatively cleaner process steam, but, still in steam line, install filter in order to tackle little scale crust and other particulate.
When what carry through reduction valve is not steam, but abrasive suspension just brings some specific questions for example during vanadine suspension.After the short time, the degree deficiency that pressure is reduced owing to high wear rate, thus and no longer can keep the specified value be scheduled to.
The objective of the invention is, produce under the situation of above-mentioned shortcoming avoiding, make a kind of reduction valve that is used for abrasive suspension, when being convenient to safeguard, it can have long working life.
The feature that is proposed in the claim of purpose of the present invention by the application protection reaches; be that the valve box is made of spherical housing; spherical housing and cylindrical throttle valve body adjoin; nozzle needle is bearing in the spherical housing; it can move along the direction of gate throttle; stretch out from spherical housing on the top of nozzle needle, and insert in the cylindrical throttle valve body.By accompanying drawing an instantiation is elaborated below.
Two opposed vertically flanges 6,7 are housed in spherical housing 1, are provided with the bearing 8,9 of nozzle needle 3 in the flange.Insert in the cylindrical throttle valve body 2 on the top 4 of the nozzle needle 3 that can screw out, and is provided with gate throttle 5 at this end.The diameter of gate throttle 5 is all the time greater than the nozzle needle 3 that inserts wherein, that is the diameter on its top 4.This has just prevented the complete atresia reduction valve.
Abrasive suspension is through the 10 inflow spherical housings 1 that enter the mouth, flow in throttle valve body 2 and the gate throttle 5 through flange 6 therefrom again, nozzle needle 3 can be driven vertically by servomotor (not shown) and move, and therefore variation has taken place in the throttling cross section that forms between the top 4 of nozzle needle and gate throttle 5 walls.The control signal of servomotor is taken from the outlet of gate throttle 5 by the pressure transducer (not shown).This control signal also can be taken from the front of spherical housing 1, so that regulate the pressure at this place.
