Abstract
The utility model discloses a direct -acting pressure reduction valve, its characterized in that: it includes valve body, disk seat, case, regulation pole, adjusting collar and push rod, the adjusting collar install the one end at the valve body, adjust the pole and pass gland nut and install in the adjusting collar, the other end at the valve body is installed to the disk seat screw, the push rod is through installing in same one side of disk seat with the valve body cooperation, the case passes through the steel ball and installs and install inside the disk seat with the push rod contact, the whole exterior structure of direct -acting pressure reduction valve is close with the general appearance of SUN valve. To be provided with O type circle sealed adjusting collar and valve body junction. The valve body on be provided with the drain tap. The utility model discloses practiced thrift installation space, it corresponds jack can borrow SUN jack shaping sword, and easily processing has avoided the hydraulic oil seepage of spring cavity outside to the valve body, has guaranteed its outward appearance aesthetic property, and O type circle sealing method reliability is high, greatly increased its life.
Description
Technical field
This utility model relates to a kind of air relief valve, is specifically related to a kind of direct acting pressure.
Background technology
Direct acting pressure, as the one of air relief valve, is used in the hydraulic system of low pressure or low discharge.The most existing
Direct acting pressure installation form great majority be board-like, take installing space relatively big, the Direct Action Type of minority screw thread inserting type subtracts
Pressure valve is not owing to having special drain tap, and long-time application hydraulic oil can leak into outside valve body, affects the outward appearance of air relief valve；Again
Person, mostly is linear sealing at the sealing between air relief valve oil-in and pressure-reduction outlet, easy to wear at life-time service seal line, thus causes subtracting
Pressure disabler.
Utility model content
For drawbacks described above and deficiency present in prior art, this utility model provides a kind of direct acting pressure.
This utility model is achieved by the following technical solution: direct acting pressure, and it includes valve body, valve seat, valve
Core, adjusting rod, regulation set and push rod, described regulation set is arranged on one end of valve body, and adjusting rod is arranged on through sealing nut
In regulation set, valve seat is threadably mounted at the other end of valve body, and push rod is arranged on the same side of valve seat with valve body by coordinating, described
Spool contacts installation by steel ball and is arranged on inside valve seat with push rod；Direct acting pressure integral outer structure is logical with SUN's
Close by profile, may be mounted to the common jack of SUN.
Described regulation set and valve body junction are provided with O and seal, to ensure that fluid does not exosmoses.
It is provided with drain tap, it is simple to the hydraulic oil in valve body inner spring chamber leads to fuel tank on described valve body.
Additionally, the outside of described valve seat is additionally provided with the O matched with SUN common jack, to ensure decompression effect
Really.
This utility model has saved installing space, and its corresponding jack can use SUN jack forming cutter, it is easy to processing, it is to avoid
The hydraulic oil of spring cavity leaks into outside valve body, it is ensured that its cosmetic look, and O sealing means reliability is high, significantly
Add its service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure, 1, valve body, 2, valve seat, 3, spool, 4, adjusting rod, 5, regulation set, 6, push rod, 7, O seal, 8, seal
Nut, 9, O seal, 10, steel ball, 11, drain tap.
Detailed description of the invention
Below by the embodiment of indefiniteness and combine accompanying drawing to utility model further instruction:
As shown in drawings, direct acting pressure, it includes valve body 1, valve seat 2, spool 3, regulates 4 bars, regulation set 5 and push rod
6, described regulation set 5 is threaded connection the one end being arranged on valve body 1, and adjusting rod 4 is by the threaded installation of sealing nut 8
In regulation set 5, it is additionally provided with O between described regulation set 5 and valve body 1 and seals 9, to ensure that fluid does not exosmoses.
Valve seat 2 is threaded connection the other end being arranged on valve body 1, and push rod 6 is arranged on valve seat 2 by coordinating with valve body 1
The same side, spool 3 contact installation by steel ball 10 with push rod 6, is arranged in inside valve seat 2, valve seat 2 and fixing seat screw thread company
Connect, with the position of fixed spool 3；Direct acting pressure integral outer structure is close with the generic external shape of SUN, may be mounted to SUN
Common jack, saved installing space, it is easy to processing.It is additionally provided with O between described valve seat 2 and SUN common jack
Seal 7, to ensure effect of easing stress.It is additionally provided with drain tap 11, it is simple to the hydraulic oil in valve body 1 inner spring chamber leads on described valve body 1
Toward fuel tank.
