This utility model is achieved through the following technical solutions：
A kind of control valve of valve controlling type accumulator, including T-shaped valve seat, valve element and valve gap, the top surface of the valve seat
Be provided with mounting groove, the valve element is screwed onto in the mounting groove, the valve gap lid is located at the top surface of the valve seat, the valve element by
The mounting groove is divided into upper and lower annular seal space, institute by the connecting portion on top and the conical seal composition of bottom, the connecting portion
The top surface for stating valve seat is provided with the air discharge duct connected with the upper annular seal space, and upper and lower annular seal space is communicated with the connecting portion
Exhaust hole, the bottom land of the mounting groove are provided with tubaeform through hole of the osculum in upper end, and the conical seal is pressed on loudspeaker
On the osculum of shape through hole, between the conical seal and lower annular seal space, gap is left.
The further improvement project of this utility model is, the outer peripheral face of the valve element connecting portion is periphery, the installation
Groove is circular trough, and the periphery is provided with and is coordinated the external screw thread being spirally connected with the mounting groove.
The further improvement project of this utility model is, the vertical portion outer peripheral face of T-shaped valve seat be provided with middle cover of battery
The external screw thread that is connected of steam vent, the externally threaded upper end on the valve seat is provided with sealing ring.
The further improvement project of this utility model is that the osculum diameter of the tubaeform through hole is less than the bottom land of mounting groove
Footpath.
The further improvement project of this utility model is that the conical surface of the conical seal props up the osculum of tubaeform through hole
Inner edge.
The further improvement project of this utility model is that the conical seal is made using quality of rubber materials.
The further improvement project of this utility model is that the bottom surface of the valve gap is provided with fixed lobe, sets on the valve seat
There is the slot coordinated with the fixed lobe.
The further improvement project of this utility model is that the upper sealing intracavity is provided with air filter piece.
Compared to the prior art this utility model has advantages below：
This utility model simple structure, is scalable pressure, the sealing of valve element and the contact of valve seat by rotary spool
For linear contact lay, whole sealing structure is linear contact lay, greatly shortens valve-closing time, it is to avoid because of the battery dehydration that valve-closing time length is caused
Phenomenon, greatly prolongs battery life.
