Abstract
The invention relates to the technical field of stop valves, in particular to a pneumatic type two-position two-way stop valve used in a pneumatic system. The pneumatic type two-position two-way stop valve comprises a valve body which is provided with an air inlet and an air outlet, pistons are arranged in the valve body, and a partition plate is arranged in the valve body. The partition plate divides the valve body into a pneumatic cavity and a control cavity which are the same in size, the pneumatic cavity is provided with an air injection opening, and each piston is in an H shape formed by two cross bars. The two pistons move synchronously to be arranged in the pneumatic cavity and the control cavity respectively. A spring is arranged between each piston and the corresponding cavity, the springs are not stressed in a normal state, and the length of the springs is half the length of the pneumatic cavity. The air inlet and the air outlet are formed in the positions, corresponding to the left side and the right side of the piston of the control cavity, of the valve body respectively, compressed air is used for controlling, the structure is simple, and control is reliable.
Description
Technical field
The present invention relates to stop valve technical field, be specifically related to the pneumatic type bi-bit bi-pass stop valve in pneumatic system.
Background technique
The advantages such as stop valve is often used in pneumatic system as a kind of control unit, and it is little that stop valve has opening degree, comparatively durable, easy to manufacture, are not only applicable to mesolow, and are applicable to high pressure.But existing stop valve adopts Electronic control mostly, need extra automatically controlled part, complex structure, adds cost.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides pneumatic type bi-bit bi-pass stop valve, controls with pressurized air, and structure is simple, controls reliable.
The present invention solves its technical problem by the following technical solutions:
Pneumatic type bi-bit bi-pass stop valve, comprise and be provided with suction port, the valve body of air outlet, valve inner is provided with piston, described valve inner is provided with dividing plate, valve inner is divided into two chambers in left and right by dividing plate, left side is pneumatic cavity, right side is control chamber, pneumatic cavity is provided with gas injection port, described piston is the I shape that double-piston is formed, connect with cross bar between double-piston, cross bar is through dividing plate, double-piston is separately positioned in pneumatic cavity and control chamber, spring is equipped with between piston with corresponding chamber, control chamber inner spring one end is connected the other end with inwall on the right side of control chamber and is connected with on the right side of piston, pneumatic cavity inner spring one end is connected the other end with pneumatic cavity inner left wall and is connected with on the left of piston, do not stress under described spring normality, its length is the half of pneumatic cavity length, described suction port, air outlet is separately positioned on valve body corresponding to the control chamber piston left and right sides.
Described dividing plate is provided with the hole passed for cross bar, is provided with seal ring between dividing plate and cross bar.Seal ring improves the tightness between two chambers.
Described its length is equal, two-piston Inter cross bar and spring isometric.Spring is to the effect of its auxiliary reset of piston, and piston and spring are the half of pneumatic cavity length, and pneumatic cavity is identical with control chamber length.
Described suction port, air outlet are all in the position of valve body within the range of movement of control chamber piston.
The invention has the beneficial effects as follows: adopt such scheme, utilize the change of pressurized gas in pneumatic cavity to control double-piston to be synchronized with the movement, no matter pneumatic cavity is inflated or venting, and suction port and air outlet all can be made to connect, react more sensitive, the simple pneumatic control of structure is more suitable for pneumatic system.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is cross section structure schematic diagram of the present invention.
Wherein: 1 is valve body, 2 is piston, and 3 is gas injection port, and 4 is suction port, and 4.1 is air outlet, and 5 is dividing plate, and 6 is cross bar, and 7 is seal ring, and 8 is pneumatic cavity, and 9 is control chamber, and 10 is spring.
