Abstract
The invention belongs to pressure regulator valve manufacturing process, and in particular to a kind of pressure regulator valve production technology.The pressure regulator valve production technology, --- laser marking --- setting pressure regulation power --- valve leakage --- dress O-ring --- dress strainer --- 100% visual inspection specifically includes the following steps: pre-assembled.The beneficial effect is that: a kind of pressure regulator valve production technology assembly of the present invention is simple, and investment amount is small, high degree of automation, the wide advantage of appropriate products, simultaneously because the stronger feature of press device flexibility is set, so that product qualification rate improves.
Description
Technical field
The invention belongs to pressure regulator valve manufacturing process, and in particular to a kind of pressure regulator valve production technology.
Background technique
In existing pressure regulator valve production technology, wherein most importantly pressure process is set, since product itself designs original
Cause, cause current setting adjust pressure process can only by the physical deformation of punching press come compressed spring to carry out setting pressure, by
Part has carried out physical deformation after punching press, so that can not rebound if punching press physical deformation is excessive, can not do over again,
It will lead to that set pressure unqualified, so as to cause scrap of the product.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of pressure regulator valve production technologies.
A kind of pressure regulator valve production technology of the invention, specifically includes the following steps: pre-assembled, --- laser marking --- is set
Pressure of setting the tone --- valve leakage --- dress O-ring --- dress strainer --- 100% visual inspection.
Further, when the setting pressure regulation power, by screw part tail springs seat come so that spring-compressed to generating
Pressure, during screwing, system can be monitored and feed back to spring compression force at the moment, and system passes through the power of monitoring
Size, which compensates, to screw: if monitoring the pressure value greater than setting, convolution spring base being carried out to make it so that spring force becomes smaller
Reach setup pressure value, then stops screwing after qualified；If monitoring the pressure value less than setting, continue to screw spring base come so that
Spring force increases, and reaches setup pressure value, then stops screwing after qualified.
The beneficial effects of the present invention are: a kind of pressure regulator valve production technology assembly of the present invention is simple, investment amount is small, automation
Degree is high, the wide advantage of appropriate products, simultaneously because the stronger feature of press device flexibility is set, so that product qualification rate mentions
It is high.
Specific embodiment
Specific embodiments of the present invention are given below, for further explaining the composition of the present invention.
A kind of pressure regulator valve production technology of the invention, specifically includes the following steps: pre-assembled, --- laser marking --- is set
Pressure of setting the tone --- valve leakage --- dress O-ring --- dress strainer --- 100% visual inspection.
Further, when the setting pressure regulation power, by screw part tail springs seat come so that spring-compressed to generating
Pressure, during screwing, system can be monitored and feed back to spring compression force at the moment, and system passes through the power of monitoring
Size, which compensates, to screw: if monitoring the pressure value greater than setting, convolution spring base being carried out to make it so that spring force becomes smaller
Reach setup pressure value, then stops screwing after qualified；If monitoring the pressure value less than setting, continue to screw spring base come so that
Spring force increases, and reaches setup pressure value, then stops screwing after qualified.
A kind of pressure regulator valve production technology of the invention carries out the process for setting pressure by screwing compressed spring, so that
If pressure qualification rate is higher, flexibility is stronger.
The present invention is not limited to the above-described embodiments, anyone should learn make under the inspiration of the present invention with the present invention
With same or similar technical solution, fall within the scope of protection of the present invention.
Claims (2)
1. a kind of pressure regulator valve production technology, which is characterized in that specifically includes the following steps: pre-assembled, --- laser marking --- is set
Pressure of setting the tone --- valve leakage --- dress O-ring --- dress strainer --- 100% visual inspection.
2. a kind of pressure regulator valve production technology according to claim 1, it is characterized in that: passing through rotation when the setting pressure regulation power
It twists part tail springs seat to come so that spring-compressed is to generate pressure, during screwing, the system meeting moment is to spring-compressed
Power is monitored and is fed back, and system is compensated by the size of the power monitored and screwed: if monitoring the pressure greater than setting
Force value carries out convolution spring base to reach setup pressure value, then stop screwing after qualified so that spring force becomes smaller；If prison
The pressure value less than setting is measured, continues to screw spring base setup pressure value to be reached, after qualified so that spring force increases
Then stop screwing.
