Abstract
The invention discloses a kind of crystallization-preventive regulating valve of valve arrangement, its valve stem contacts heater, makes the hull-skin temperature of valve rod remain crystalline temperature temperature higher than crystal, prevents crystallization from reducing frictional force, so as to ensure that valve rod swimmingly does piston movement, make whole valve normal work.
Description
Technical field
The invention belongs to valve arrangement, and in particular to a kind of crystallization-preventive regulating valve.
Background technology
In nonferrous smelting industry, oxygen leaching regulating valve need to possess corrosion resistant, antiscour, anti-particle, anti-caking in reactor
Brilliant operating mode.The resistance when valve rod of regulating valve does piston movement in valve seat is essentially from frictional force, if there is knot in valve seat
Brilliant thing (such as crystallization sulphur), then can increasing friction force, if frictional force has exceeded piston power, valve rod will be stuck.Once valve
Badge is dead, directly affects the normal operation of reactor, forces emergency shutdown to overhaul.
The content of the invention
The technical problem to be solved in the present invention is to overcome the defect of prior art there is provided a kind of regulating valve of crystallization-preventive.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of crystallization-preventive regulating valve, including with
The valve body of the hollow structure of charging aperture and discharging opening, valve body, which is plugged with, can do the valve rod of piston movement, and valve rod is located at discharging opening
The inserting paragraph of same axis and valve rod withstands discharging opening, the section of stretching out connection driver of valve rod, the valve stem contacts heater, with
Prevent crystallization.
Further, the inside of the valve rod sets heater.
The heater is resistance wire.
The end of the valve rod inserting paragraph connects the valve element of conical structure, and valve element withstands discharging opening.
The outside parcel sleeve of the connecting portion of the valve body and valve element.
The junction of the valve rod and valve body has space, and guide ring and filler are disposed with this space.
The valve body sets valve seat, and valve rod is inserted in valve seat.
The beneficial effect that is reached of the present invention is：Due to valve stem contacts heater, the hull-skin temperature of valve rod is set to protect all the time
The crystalline temperature temperature higher than crystal is held, prevents crystallization from, to reduce frictional force, so as to ensure that valve rod swimmingly does piston movement, making
Whole valve normal work.
Brief description of the drawings
Fig. 1 is the structural representation of crystallization-preventive regulating valve.
Fig. 2 is the structural representation of valve rod.
Embodiment
As shown in figure 1, regulating valve is mainly made up of valve body 4, valve seat 8, valve rod 1 and valve element 5.
Valve body 4 is hollow structure cavity, and its sidepiece opens up charging aperture, and bottom opens up discharging opening.On the inside of the discharging opening of valve body 4
Insert expects pipe 3.Valve seat 8 is installed on the top of valve body 4, and the center of valve seat 8 opens up through hole.
The through hole of valve seat 8 plants valve rod 1, and the head end of valve rod 1 passes through through hole and stretched into the inner chamber of valve body 4.Valve rod 1 is axle
Shape structure, the axis of valve rod 1 is overlapped with the axis of expects pipe 3.The end face connection valve element 5 of the inserting paragraph of valve rod 1.The head end of valve rod 1 and
The periphery parcel sleeve 9 of the first half of valve element 5.The lower half of valve element 5 is in cone shape, external diameter and the expects pipe 3 of the lower half of valve element 5
Internal diameter be engaged.Valve element is used to adjust fluid flow, and different valve element shapes, regulation form is different, also can be according to different medium
Do the valve element of corresponding material, such as special cermacis PSZ, Hastelloy.
Space is formed between the through hole madial wall of valve seat 8 and the lateral surface of valve rod 1, the He of filler 11 is provided with the space
Guide ring (support ring) 12, to fix valve rod.
The upper mounting bracket 10 of valve seat 8, support 10 installs transfer bar mechanism 13, the connection push rod 2 of transfer bar mechanism 13, push rod 2
Shaft coupling 6 is connected, shaft coupling 6 connects the section of stretching out of valve rod 1.Push rod is achieved a butt joint with valve rod by shaft coupling 6.Transfer bar mechanism can
To be cylinder.
Heater 7 is planted in the axle center of valve rod 1, and heater is used to heat valve body, removes crystallization.Heater 7 is by the He of housing 7.1
Thermal resistance 7.2 is constituted, and housing is made up of ceramic armour material, and resistance wire 7.2, the connection power line of resistance wire 7.2 are set in housing 7.1
7.4 and temperature sensor 7.3.Valve rod is heated to more than 115 degree by heater, can prevent crystal.
Crystallization-preventive regulating valve, it is adaptable to nonferrous smelting control line, with high temperature resistant, resist crystallization, resistance to erosion and corrosion resistant
Feature, making modularization, fabrication cycle are short, made exclusively for oxygen leaching technique.
