Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Embodiment.
Referring to Fig. 1 to Fig. 4.
A kind of through type of the utility model embodiment can shut off the safe hydraulic pressure connection valve of voltage stabilizing, including valve body 1 and valve rod
2, valve rod 2 is located in valve body 1, the hexagonal bar shape of shape of valve body 1.
In the utility model embodiment valve body 1 contain three-stage inner cavity, be followed successively by first inner chamber 1-1, second inner chamber 1-2 and
Third inner cavity 1-3.It is equipped with joint screw thread in first inner chamber 1-1 and third inner cavity 1-3, is respectively used to connection flexible pipe and hard tube.
Between first inner chamber 1-1 and second inner chamber 1-2 setting there are one through-hole 1-4 and six oil outlets 1-5, six oil outlet 1-5 with
It is rounded uniformly distributed centered on through-hole 1-4, a diameter of 5.5mm of a diameter of 6mm of oil outlet 1-5, through-hole 1-4.Second inner chamber 1-2
Third inner cavity 1-3 is provided with conical hole 1-6.
Valve rod 2 includes taper end and butt end in the utility model embodiment.The butt end of valve rod 2 is located in the 1-3 of third inner cavity,
Ontology is in a circular table shape, is closed with the matching size of conical hole 1-6.The taper end of valve rod 2 sequentially passes through conical hole 1-6 and through-hole 1-4 stretches
Into in first inner chamber 1-1, it is equipped with spring 3 thereon, spring 3 is located at second inner chamber 1-2 and the by the way that conical hole 1-6 is telescopic
In three inner cavity 1-3.The end set of the taper end of valve rod 2 has screw thread, for connecting for the end of taper end to be limited in first
The nut 4 of chamber 1-1.
Pressure relief vent 1-7 is further opened in the utility model embodiment on valve body 1, is communicated with third inner cavity 1-3, pressure relief vent
Joint screw thread is equipped in 1-7, for installing pressure measuring tie-in.
A diameter of 12mm of spring 3 in the utility model embodiment.
The use state of the utility model embodiment in normal operation is：The taper end of valve rod 2 puts on spring 3, according to
It is secondary to be put in first inner chamber 1-1 across conical hole 1-6 and through-hole 1-4, and be limited in first inner chamber 1-1 by nut 4；
