Specific implementation mode
As shown in Figure 1 to Figure 2,
A kind of commutation type equalizer valve includes valve body 9, and upper cover plate 4 and bottom plate 16 are equipped on the valve body 9, and described is upper
It is equipped with first guide bracket 3 on cover board 4, electromagnet coil component 1 is provided on elder generation's guide bracket 3, valve rod is equipped in the valve body 9
10, it is provided with spring 15 between the valve rod 10 and the bottom plate 16,10 middle part of valve rod is provided with cage ring 10a, described
Valve body 9 in the both sides of cage ring 10a be respectively formed with A chambers and B chambers, the A chambers are connected with the first stomata, described
B chambers are connected with the second stomata；The shuttle valve core 12 that can be moved in shuttle valve chamber 9a is also equipped in the valve body 9, it is described
The both sides of shuttle valve core 12 be respectively arranged with shuttle valve end cap 5, the holes A1 communicated with A chambers are offered on side shuttle valve end cap 5, it is another
The holes B1 communicated with B chambers are offered on side shuttle valve end cap 5, the holes A1 and the holes B1 are communicated with shuttle valve chamber 9a；The shuttle valve
After core 12 moves, the shuttle valve chamber 9a is conducted with first guide bracket 3.
First guide bracket 3 is fixed with upper cover plate 4 by cross flat head bolt 2, passes through bottom bolts 18 between bottom plate 16 and valve body 9
It is fixed.
Valve rod 10 is matched with electromagnet coil component 1, and when electromagnet coil component 1 powers off, equalizer valve is closed, electromagnet
When coil block 1 is powered, valve rod 10 overcomes the elastic force of spring 15 to move right.
Spring retention chamber is offered on the valve rod 10, the spring 15 is placed in the spring retention intracavitary.
The periphery of the cage ring is equipped with c-type sealing ring 14.
