Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As shown in Figure 1-2, the High Pressure Difference high temperature angle valve described in this utility model embodiment, including valve body 1, be arranged on described
Valve rod 4 that valve seat 2 in valve body 1, the spool 3 being arranged in described valve seat 2 are connected with described spool 3 and be arranged on described valve
The bonnet, 5 at body 1 top, it is internal that described spool 3 is fully mounted at described valve seat 2, is welded with at the fluid intake of described valve body 1
Throttling element 6；Described spool 3 is threaded connection with described valve rod 4, and described valve rod 4 is through described valve seat endoporus, described valve rod 4
It is arranged in described bonnet, 5；Described bonnet, 5 is connected by stud 7 with described valve body 1.
Spool is positioned at inside valve seat, the impulsive force of spool is greatly reduced by fluid, it is to avoid spool is in high pressure for a long time
In difference working environment, and the problem causing the blastic deformation of spool.The tune of flow is realized by the distance adjusting valve seat and spool
Whole.Valve seat construction uses unique extension design, reduces fluid and washes away outlet.The spool of whole tungsten carbide and valve seat tool
There is longer service life.
Weld throttling element at fluid intake, reduce the flow velocity of fluid intake, thus reduce the impact to trim.Joint
Stream part can be welded on valve body side or bottom, according to actual demand, it is achieved valve body fluid side is entered or valve body fluid bottom surface is entered
Enter.
In this example, described spool 3 is Pyatyi buck parabolic structure, makes pressure reduce step by step, and this structure is suitable for high pressure
