Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, technical scheme of the present invention will be carried out below
Detailed description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work
Other embodiment belongs to the range that the present invention is protected.
Referring to Fig. 1-Fig. 3, the present invention provides a kind of inner pressed flow control valve, including valve body 1, valve deck 2 and flashboard 3,
Wherein, valve deck 2 is connected with valve body 1, and flashboard 3 is located in valve body 1 and flashboard 3 can be moved along the direction of 3 central axis of flashboard, valve
It is the part-structure for forming liquid containing chamber 4 that liquid containing chamber 4 and flashboard 3 are provided in body 1, and liquid containing chamber 4 can accommodate liquid
When accommodating liquid in body and liquid containing chamber 4, the liquid in liquid containing chamber 4 and the liquid from the entrance of 1 inlet 11 of valve body
The two sides of flashboard 3 can be respectively acting on and position of the flashboard 3 in valve body 1 can be adjusted under the collective effect of the two.It is existing
Flow control valve need to configure flashboard driving mechanism, such as pneumatic control valve, need to configure cylinder, air compressor so that
The complicated of flow control valve, cost of manufacture are high；And interior 1 pressure type flow control valve provided by the invention, it is not necessarily to above structure,
It is respectively acting on flashboard 3 by liquid in liquid containing chamber 4 and the liquid entered from 1 inlet 11 of valve body to adjust flashboard
3 position in valve body 1, and then the adjusting to fluid flow is realized, for example, when there is no liquid in liquid containing chamber 4, from
The liquid that 1 inlet 11 of valve body enters can push flashboard 3 to be moved extremely to close to the direction of valve deck 2 along 3 central axis of flashboard
Extreme position so that flashboard 3 is in full open position；When liquid containing chamber 4 has partially liq, by liquid containing chamber 4
Liquid and the liquid that enters from 1 inlet 11 of valve body can be respectively acting on the both sides of flashboard 3, flashboard 3 is in two side hydraulic pressures
Reach equilibrium state under effect；When hydraulically full in liquid containing chamber 4, the liquid in liquid containing chamber 4, which applies flashboard 3, presses
