Description
Technical field
This utility model relates to valve element technical field, particularly relates to a kind of direct-acting valve.
Background technology
Water hydraulics is using natural fresh water, sea water or tap water proxy mineral oil as hydraulic pressure system
The new technique of system working media, as hydraulic technology, belongs to hydraulic transmission technology.?
In the development process of hydraulic transmission technology, the media that water transmits as power, exchanges and control
Once very important effect was played.In shortage of resources and today of promotion environmental protection, should use water as
Working media for hydraulic transmission technology mainly has following advantage: 1, ecological friendly, ring
Protect pollution-free；2, clean and safe, can avoid fire；3, cheap, wide material sources；
4, it is easily maintained and maintains.Hydraulic valve as one of the core parts of Hydraulic Drive Technology, its
Performance quality is most important to whole hydraulic system.
Overflow valve is a kind of pressure-control valve, has level pressure, overload protection (safety) and off-load
Deng multiple use.The static characteristic of overflow valve is required mainly have: keying characteristic is good, response
Hurry up, unloading pressure is low, good airproof performance etc.；Requirement to its dynamic characteristic mainly has: dynamically surpass
Tune amount is little, transit time is short, pressure stability is good.
Current direct-acting overflow valve (abbreviation direct-acting valve), in use, valve body with
Sealing property at valve gap is poor, is easily caused leakage, especially in hydraulic pressure direct acting
Valve, owing to the viscosity of the water ratio for hydraulic oil that compares is relatively low, is more prone to cause leakage.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that Yi Zhongzhi
Dynamic valve.
This utility model is to be achieved through the following technical solutions:
A kind of direct-acting valve, including valve body, valve gap, valve rod, the valve that is built in described valve body
Core, valve handle, valve pocket, described valve gap is arranged on described valve body, and described valve rod is with described
Spool is connected, and valve rod is connected through valve gap with described valve handle, and described valve pocket is arranged on described
