Abstract
The utility model relates to valve sleeves used in a kind of regulating valve, four column hole groups are circumferentially evenly equipped with including cylinder, on the barrel wall, there are five the threaded holes being axially distributed along barrel wall for each column hole group tool, flow block is connected in the threaded hole, flow block center offers metering orifice.The flow block for being passed through liquid medium is threadedly attached on cylinder by the utility model, in this way when sleeve blocking occurs, it can be with quick-replaceable flow block, improve maintenance efficiency, especially when technological parameter changes, only flow block need to be directly replaced by traffic requirement, to improve the service life of valve, guarantee the long-period stable operation of produced on-site.
Description
Technical field
The utility model relates to hydraulic valve technology, valve sleeve used in especially a kind of regulating valve.
Background technique
Regulating valve is the terminal filed regulation meter in robot control system(RCS), it is mounted on process pipe, is adjusted by tune medium
Flow, by sets requirement control technological parameter.Regulating valve directly contacts high temperature, high pressure, deep cooling, deep-etching, high viscosity, Yi Jie
Close-burning is brilliant, the process fluids medium such as toxic, thus be easiest to be corroded, erosion, cavitation, the instrument of aging, damage, often give
The control of production process causes difficulty.The valve sleeve window of regulating valve is generally window type and perforating type.Wherein perforating type set
Cylinder is having particle, in the medium for having crystallization, be easy to cause valve blockage, while particle at punching and crystallization are easy to pull set
Cylinder inner wall, causes spool to be pulled, valves leakage, bite.In some operating conditions, since technological parameter change leads to the adjustable model of valve
It encloses to change and causes valve surge phenomenon.Simultaneously punch sleeve blocking after generally need it is offline after could clear up, wash away seriously
Need replacing spare part or re-work, increase maintenance cost.
Summary of the invention
Technical problem to be solved by the utility model is: the utility model provides in order to overcome the deficiencies in the existing technology
A kind of achievable quick-replaceable sleeve reduces valve sleeve used in the regulating valve of maintenance cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows: valve sleeve used in a kind of regulating valve, packet
Cylinder is included, four column hole groups are circumferentially evenly equipped on the barrel wall, there are five the spiral shells being axially distributed along barrel wall for each column hole group tool
Pit is connected with flow block in the threaded hole, and flow block center offers metering orifice.
Preferably, the threaded hole is the internal screw thread of M12, and flow block outer diameter is M12 external screw thread, in the group of each column hole up and down
Center is away from for 13mm between adjacent threaded hole.
To meet different flow needs, the aperture of the metering orifice is φ 8mm or φ 5mm or φ 4mm or φ 2.5mm.
The beneficial effects of the utility model are: the flow block for being passed through liquid medium is threadedly attached in by the utility model
On cylinder, in this way when sleeve blocking occurs, maintenance efficiency can be improved with quick-replaceable flow block, especially be sent out in technological parameter
In the case of raw change, only flow block need to be directly replaced by traffic requirement, to improve the service life of valve, guarantee that scene is raw
The long-period stable operation of production.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1. cylinder, 2. threaded hole, 3. flow block, 4. metering orifice
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Valve sleeve used in a kind of regulating valve as shown in Figure 1, including cylinder 1 are circumferentially evenly equipped on 1 wall of cylinder
Four arrange hole groups, are in the horizontal direction in 90 degree of angles between the group of each column hole.
There are five the threaded holes 2 being axially distributed along 1 wall of cylinder for each column hole group tool, amount to 20 threaded holes 2, each column hole group
In between neighbouring threaded hole 2 center away from for 13mm.The threaded hole 2 is the internal screw thread of M12, in each threaded hole 2
It is connected with the externally threaded flow block 3 of M12,3 center of flow block offers metering orifice 4, and the aperture of the metering orifice 4 is φ
Several specifications of 8mm or φ 5mm or φ 4mm or φ 2.5mm.
The utility model changes traditional direct mode punched on cylinder 1, will be passed through the flow block 3 of liquid medium
It is threadedly attached on cylinder 1, in this way when sleeve blocking occurs, maintenance efficiency can be improved with quick-replaceable flow block 3,
Especially when technological parameter changes, only flow block 3 need to be directly replaced by traffic requirement, to improve valve
Service life, guarantee the long-period stable operation of produced on-site.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
