Abstract
Multiviscosisty is hydraulic system relief valve for appearance, the problem that will solve is that the miniature air pump that has now or air compressor machine are after the shut down, also have certain atmospheric pressure to exist in the cylinder, starting next time make air pump or air compressor machine when, the start -up load of motor is great, the energy consumption is higher, life is shorter, its multiviscosisty is hydraulic system relief valve for appearance is the interior unnecessary gas of mode release cylinder that adopts manual pressure release, inconvenient operation, and miniature air pump or the too high problem of air compressor machine ubiquitous during operation atmospheric pressure, influence normal use, the utility model provides a being fixed with the proscenium on the procapsid, being fixed with the spring holder on the back casing, be provided with the diaphragm between procapsid and back casing, the geometric centre position of diaphragm is provided with the valve rod, and the one end of valve rod is provided with the needle, and it is together fixed with the spring holder separation blade that the other end passes the diaphragm, and the needle fills up through the direction and the seal cover inserts in the valve body.
Description
Technical field
The utility model belongs to multiviscosity meter hydraulic system Decompression valves technical field, is specifically related to a kind of multiviscosity meter hydraulic system Decompression valves being applied to quality detection apparatus.
Background technique
Existing hydraulic system after a shutdown; certain air pressure is also had to exist in oil hydraulic pump; make hydraulic system when starting next time; the startup load of motor is comparatively large, and energy consumption is higher, and working life is shorter; its Decompression valves adopts the mode of manual pressure release to discharge excessive gas in cylinder; operation inconvenience, and the problem that during work of hydraulic system ubiquity, air pressure is too high, impact normally uses.
Summary of the invention
The purpose of this utility model is to provide a kind of multiviscosity meter hydraulic system Decompression valves being applied to quality detection apparatus.
The purpose of this utility model realizes like this, it comprises: front case and rear case, it is characterized in that: front case is fixed with foreground, rear case is fixed with spring seat, between front case and rear case, be provided with diaphragm, the geometrical center position of diaphragm is provided with valve rod, and one end of valve rod is provided with needle, the other end is fixed together through diaphragm and spring seat catch, and needle is inserted in valve body by guiding pad and stuffing box gland.
Described diaphragm is the dish-shaped sheet with sealing edge.
Be provided with O shape circle between foreground and front case, between rear case and spring seat, be provided with O shape circle.
Be provided with spring between spring stop piece and spring seat, the end of spring seat is also provided with adjusting bolt.
The utility model has the advantages that: this multiviscosity meter hydraulic system Decompression valves can discharge gas unnecessary in cylinder; when air pump is started; be in normal atmosphere pressure condition; reduce electric motor starting load; can save energy energy consumption, and when air pump air pressure exceeds setting pressure, can be exitted by multiviscosity meter hydraulic system Decompression valves; shield, increase the service life.
