The structure of this product can be made more compact again, save space, volume may be reduced unexpectedly simultaneously in the performance for guaranteeing this product.
As shown in Figure 1, being provided with the first O-ring 7 between the aperture and telescopic rod 31 of counterbore 111 in the present embodiment;Mushroom
The second O-ring 8 is provided between head sleeve joint hole 121 and mushroom head 32;It is O-shaped that third is provided between pressure holes 123 and top pillar 51
Circle 9.Above-mentioned O-ring is arranged in the present invention, and the sealing performance inside this product can be effectively ensured.
As shown in Figure 1, in the present embodiment, the top side of telescopic rod 31 offers radial side opening 311, side opening 311 with
The macropore of counterbore 111 communicates, which is set to the front end of the first O-ring 7;The top of the mushroom head 32 of mandril 3 offers
Penetrate through the venthole 323 of side opening 311.Above-mentioned side opening 311 and through-hole 323 is arranged in the present invention, it is ensured that the macropore of counterbore 111
With the perforation between the space at the second pressure spring 4, guarantees that the pressure stable phase at two is same, both guaranteed the pressure at pressure export
It is always consistent with the pressure at the second pressure spring 4, to realize that the pressure of the pressure export of this product is stablized.Example: mandril 3
Top pressure is adjusted to x, and is F in the pressure of the pressure inlets of the top end of mandril 3, is set at the macropore of counterbore 111
Pressure at the pressure of pressure export and the second pressure spring 4 is all y;As F > x+y, the top of mandril 3 is opened by pressure inlets,
The pressure and the pressure at the second pressure spring 4 for being set to the pressure export at the macropore of counterbore 111 at this time are both greater than y, and until F-x
When reach pressure stationary value;Because when pressure at the second pressure spring 4 is greater than F-x, the both pressure at the second pressure spring 4 and mandril 3
Both top pressure, which is added, is greater than F, and the top of mandril 3 is caused to block pressure inlets, and then guarantees the macropore for being set to counterbore 111
The pressure of the pressure export at place may remain in F-x value always, realize the pressure stabilizing output function of this pressure reducing valve;In addition, working as F < x+
When y, mandril 3 blocks pressure inlets always, it is possible to prevente effectively from occurring the case where pressure upstream.
As shown in Figure 1, the top of the telescopic rod 31 of mandril 3 is provided with the rubber block of matching connection in the present embodiment
312, increase the sealing performance between the top and pressure inlets of mandril 3.
The above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
It says, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
