Specific embodiment
Below against attached drawing, by the description of the embodiment, making to the specific embodiment of the present invention further details of
Explanation.
Fluid pressure type pressure retaining valve of the present invention, as shown in Figure 1, 2, including valve body 1, valve body 1 is the main component of this pressure retaining valve, in valve
Body 1 is covered with valve pocket 2.The inner cavity 11 of connection oil inlet 13 is equipped in valve body 1, oil inlet 13 is equipped with 11 junction of inner cavity and blocks
The roller plug 5 of oil inlet 13, inner cavity 11 is interior to be equipped with spring 4,5 upper end of roller plug and 4 times end in contact of spring, 11 upper end of inner cavity
The spring base 3 for being supported in 4 upper end of spring is additionally provided with, the oil outlet I 12 outside connection with inner cavity 11 is equipped on 1 side wall of valve body.
In the present invention, as shown in Figure 1,3, valve body 1 is connected by sequentially connected construction section, tapering transition section, cervical part of esophagus and screw thread
Section 15 is connect to form.Integral into hexagon socket head cap screw shape, upper end construction section tightens hole 14,15 outer wall of threaded connection section equipped with interior hexagonal
Equipped with external screw thread, for being connected in the throttle orifice of engine cylinder cover or valve chamber cover oil circuit.
In the present invention, as shown in the figure, valve pocket 2 is covered on tapering transition section and cervical part of esophagus.Oil outlet I 12 is set on cervical part of esophagus,
Valve pocket 2 is equipped with the oil outlet II 21 with I 12 corresponding connection of oil outlet.The upper end of valve pocket 2 and construction section lower face gluing, sealing,
The lower end sealing limiting of valve pocket 2 is connected on the step surface of the stretching of threaded connection section 15.
The bottom surface of inner cavity 11 is the arcuate structure face being connect with 13 transition of oil inlet, and roller plug 5 is placed in arcuate structure face
On, to ensure good closure, under usual state, oil inlet 13 is blocked by roller plug 5, is closed.
The upper end of inner cavity 11 is equipped with the limiting stand terrace of limiting clamping spring base 3.
In the present invention, inner cavity 11 is provided on valve body 1, one end of valve body 1 is provided with oil inlet 13, in valve body 1
The oil outlet 12 being interconnected with inner cavity 11 is provided on side wall；Roller plug 5 is against the oil inlet 13 of above-mentioned 1 one end of valve body
On, spring base 3 and spring 4 are arranged in the inner cavity 11 of valve body 1, and roller plug 5 is against at oil inlet 13, and one end of spring 4 is supported
On roller plug 5, the other end is mounted on spring base 3；Valve pocket 2 is in empty cup, is sleeved on valve body 1, plays rigid seal
