Abstract
The utility model provides a nuclear power is with smart small -size self -operated pressure control valve, belongs to governing valve technical field. It includes valve body, disk seat, case, valve rod, valve gap, regulating spring and adjustment disk, the valve rod top pass the adjusting nut locking through setting up behind valve body, valve gap and the adjustment disk, valve rod bottom be connected with actuating mechanism after wearing out the valve body. The utility model discloses an actuating mechanism of valve rod and valve body below is connected, can effectively reduce the assembly space requirement of valve body top, and debugging pressure control point be as long as can debug with conventional nut runner, has realized using the dismouting that the scene just can relax and the requirement of debugging at the nuclear power.
Description
Technical field
This utility model belongs to regulating valve technical field and in particular to a kind of nuclear power is adjusted with smart small-sized Self-operated pressure
Valve.
Background technology
In recent years, domestic valve industry develops rapidly, and the product structure type of each valve producer emerges in an endless stream.But it is domestic existing
Some self-contained pressure regulators, the assembly space of needs is higher, because the molding of the pipe laying on nuclear power, and arranges
Closely, existing self-contained pressure regulator space is installed and just seems that very Shan is little, valve dismounting, debugging difficulty are big, impact
The normal procedure of nuclear power production process；Existing self-contained pressure regulator needs special wrench set, versatility when adjusting pressure control point
It is restricted, this increased cost to producer, bring inconvenience to client.
Utility model content
The problem existing for prior art, the purpose of this utility model is that design provides a kind of nuclear power essence small-sized certainly
The technical scheme of power formula pressure-regulating valve.
A kind of described nuclear power with smart small-sized self-contained pressure regulator, including valve body, valve seat, valve element, valve rod, valve gap,
Adjust spring and adjustment disk it is characterised in that described valve stem top passes through the tune of setting after passing through valve body, valve gap and adjustment disk
Section nut check, described stem bottom is connected with actuator after passing valve body.
A kind of described nuclear power with smart small-sized self-contained pressure regulator it is characterised in that described actuator include with
Cylinder cap, the cylinder sleeve being arranged in cylinder cap and the piston being arranged in cylinder sleeve that body base connects, described piston is solid with valve rod
Fixed connection.
A kind of described nuclear power is with smart small-sized self-contained pressure regulator it is characterised in that between described piston and cylinder sleeve
It is equipped with sealing ring.
This utility model is connected with the actuator below valve body using valve rod, and the assembling that can effectively reduce above valve body is empty
Between require, as long as debugging pressure control point is adjustable with the nut spanner of routine it is achieved that can be light using scene in nuclear power
The dismounting of pine and the requirement of debugging.

Fig. 1 is structural representation of the present utility model.
In figure: 1- cylinder cap；2- cylinder sleeve；3- sealing ring；4- piston；5- valve body；6- valve seat；7- valve element；8- valve rod；9- valve
Lid；10- adjusts spring；11- adjusting nut；12- adjustment disk.
Specific embodiment
To further illustrate this utility model below in conjunction with Figure of description.
As illustrated, a kind of smart small-sized self-contained pressure regulator of nuclear power include valve body 5, valve seat 6, valve element 7, valve rod 8,
Valve gap 9, regulation spring 10 and adjustment disk 12, wherein valve rod 8 top pass through setting after passing through valve body 5, valve gap 9 and adjustment disk 12
Adjusting nut 11 is locked, and valve rod 8 bottom is connected with actuator after passing valve body 5.Actuator includes being connected with valve body 5 bottom
Cylinder cap 1, the cylinder sleeve 2 being arranged in cylinder cap 1 and the piston 4 being arranged in cylinder sleeve 2, piston 4 is fixedly connected with valve rod 8, piston 4
It is equipped with sealing ring 3 and cylinder sleeve 2 between.
During work, valve is in normally off, and medium direction shown in arrow enters valve body 2, by valve seat 6 and valve element 7,
Flow out through outlet.When before valve, pressure medium enters actuator upper chamber, the initial pretightning force adjusting spring 10 is by upstream pressure
Balance is destroyed, and valve rod 8 moves downward, and opens valve element 7, and medium passes through valve element 7 and after valve seat 6 sectional area flows to valve, upstream pressure
Decline.If down thrust produced by medium is equal with adjusting spring 10 pretightning force (setting power), valve element 7 aperture is motionless, works as valve
, to during less than adjusting spring 10 pretightning force, balance is destroyed for front pressure drop, adjusts spring 10 and shrinks, and tension valve element 7 valve is opened
Degree reduces, otherwise valve opening increases.Adjust the height of adjusting nut 11 with spanner, be adjustably controlled the size of pressure.
Above-mentioned is only preferred implementation under this utility model thinking, is not construed as to restriction of the present utility model, all
Belong to the technical scheme under this utility model thinking and belong to protection domain of the present utility model.It should be pointed out that for this technology
For the those of ordinary skill in field, some improvements and modifications under the premise of without departing from this utility model principle, also should be regarded as
Protection domain of the present utility model.
