Description
Technical field
This utility model relates to valve element technical field, particularly relates to a kind of modified model hydraulic valve.
Background technology
Water hydraulics is using natural fresh water, sea water or tap water proxy mineral oil as hydraulic work system
The new technique of medium, as hydraulic technology, belongs to hydraulic transmission technology.At hydraulic transmission technology
Development process in, water transmits as power, exchange and the media that control once played very important work
With.In shortage of resources and today of promotion environmental protection, the working media of hydraulic transmission technology should be used water as
Mainly there is following advantage: 1, ecological friendly, environment friendly and pollution-free；2, clean and safe, can avoid
Fire；3, cheap, wide material sources；4, it is easily maintained and maintains.Hydraulic valve passes as hydraulic pressure
One of core parts of dynamic technology, its performance quality is most important to whole hydraulic system.In view of water is situated between
The physicochemical property that matter is special, there is cavitation erosion in hydraulic valve, seal and lubrication etc. have a strong impact on service behaviour and
The problem in service life, and seem more as the water hydraulic relief valve of one of main element in hydraulic system
Prominent.So on the basis of taking into full account aqueous medium physicochemical property, in terms of structure, material etc.
Hands, researches and develops that a kind of pressure is high, good and length in service life the water hydraulic relief valve of performance is the most necessary.
But when with aqueous medium proxy mineral oil as working media, with traditional oils pressurized overflow valve design theory
Occur inharmonious between water hydraulic relief valve meeting and the hydraulic system of design, cause the most whole hydraulic pressure system of valve
System job insecurity.
In use, it is Direct Action Type hydraulic pressure overflow that wire drawing is corroded to current One-stage Water Hydraulic Relief Valve
One of FAQs in valve.Owing to the viscosity of water is low, poor lubricity, hydraulic pressure under identical working condition
The velocity ratio oil pressure valve of valve valve port is high, and high pressure, high-velocity flow are very strong to the impulsive force of spool and valve seat,
In the course of time can form a thread groove of the rule, when in current with some tiny grit, it breaks
Bad power is bigger.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of modified model water
Pressure valve.
This utility model is to be achieved through the following technical solutions:
A kind of modified model hydraulic valve, including overflow valve body, valve gap, stop nut, valve seat, spring,
Spool, the bottom of described overflow valve body offers feed pathway, and the inside of described overflow valve body offers
The valve pocket communicated with feed pathway, and offer liquid outlet channel on the outer wall of described overflow valve body, should
Direct-acting overflow valve also includes the spring seat of honour, spring lower seat, and one end contact of described spring is at described bullet
On the end face at the spring seat of honour, the other end contact of spring on the end face of described spring lower seat, described spool
Centre position, lower surface offer isosceles trapezoid groove, and on the inwall of described isosceles trapezoid groove
Offer the first through flow hole and the second through flow hole.
As optimal technical scheme of the present utility model, described a kind of modified model hydraulic valve also includes sealing
Pad, described sealing gasket is arranged between described overflow valve body and valve gap.
As optimal technical scheme of the present utility model, described first through flow hole and the second through flow hole size
Identical, the centrage along isosceles trapezoid groove is symmetrical arranged.
As optimal technical scheme of the present utility model, the end face diameter of described isosceles trapezoid groove is valve
0.3-0.5 times of core end face diameter.
Its operation principle is: when overflow valve normally works, and water under high pressure enters from feed pathway, then leads to
Crossing spool, after reaching the pressure set by spring, push spool open, water under high pressure is i.e. left from the spring seat of honour
The liquid outlet channel on limit flows out.
Compared with prior art, the beneficial effects of the utility model are: this utility model is on spool
Offer isosceles trapezoid groove, the first through flow hole, the second through flow hole, it is possible to the pressure reduction at fall spool,
Improve its anti-cavitation ability, reduce its wire drawing and corrode.
