The two-position five-way double pneumatic control reversing valve is controlled to reverse through the upper pilot valve and the lower pilot valve, so that the piston of the cylinder and the piston rod of the cylinder are controlled to reciprocate up and down in the cylinder barrel. The reversing gas signal for controlling the two-position five-way double-pneumatic reversing valve is directly connected from a gas source, so that the reversing is flexible; the two-position five-way double pneumatic control reversing valve, the pilot valve and the cylinder body are integrally installed, so that the structure is compact, great convenience is brought to installation and maintenance, and leakage is not easy to occur.
Description
Technical field:
This reality is novel to relate to a kind of pump, specifically pressurized air is inserted in the pump housing through filtering, and this pump piston drives piston rod and gets final product automatic reciprocating motion.If the piston rod output terminal is linked to each other with the oil cylinder plunger and is equipped with cylinder tube is transfusion fluid pressure, by changing the piston rod of different-diameter, can obtain different delivery pressures.Promptly be that a kind of it is applicable to that hydraulic pressure, oil pressure such as petrochemical industry, valve, tubing carry out the liquid pressure testing by the air-driven hydraulic pump of the bigger pneumatic piston of diameter to the less hydraulic plunger transmission pressure of diameter, also can be used as the hydraulic control system pressure source and use.
Background technique:
At present, known to each valve of pneumatic pump structure disperse to put, its reversing mode of pneumatic pump that is used on the pneumatic hydraulic test pump is realized with mechanical slide formula and spring steel ball locate mode, dumb, the incomplete phenomena of this kind structure ubiquity commutation.It is more to connect required exposed conduit road in addition, gives to install to overhaul and makes troubles, and is prone to accidents such as leaking termination of pumping.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of compact structure, installs and overhaul conveniently and can not leak the pneumatic pump of termination of pumping accident.
Purpose of the present utility model is achieved in that it comprises cylinder piston, cylinder piston rod, selector valve, cylinder barrel and the upper cylinder body that connects as one with cylinder barrel, lower cylinder body, it is characterized in that: described selector valve adopts two-position five-way double air controlled selector valve, and this valve adopts and board-likely links to each other with upper cylinder body; The pilot valve that is made of flower cover, striker, spring and plug is housed in upper cylinder body and lower cylinder body respectively, and this pilot valve belongs to bi-bit bi-pass spring reset machinery control selector valve; External air source communicates with upper and lower air chamber in the cylinder barrel through two-position five-way double air controlled selector valve.
When external air source entered lower chamber by two-position five-way double air controlled selector valve, cylinder piston moved up, and drives piston rod simultaneously and moves up.During the pilot valve striker, the commutation of two-position five-way double air controlled selector valve is controlled in this valve commutation simultaneously in cylinder piston collides upper cylinder body, at this moment external air source enters upper gas chamber by two-position five-way double air controlled selector valve, at this moment, cylinder piston moves down, and drives piston rod simultaneously and moves down.During the pilot valve striker, the commutation of two-position five-way double air controlled selector valve is controlled in this valve commutation simultaneously in cylinder piston collides lower cylinder body, and at this moment external air source imports upper gas chamber again, makes cylinder piston drive piston rod and moves down.When cylinder piston collided the pilot valve striker that is contained in the lower cylinder body, the commutation of two-position five-way double air controlled selector valve was controlled in this valve commutation simultaneously, and cylinder piston moves up, and drives piston rod simultaneously and moves up.To-and-fro motion so voluntarily.If piston rod output is linked to each other with cylinder plunger, and is equipped with oil suction and fuel-displaced one-way valve, hydraulic coupling output can be arranged, when hydraulic coupling that is subjected to when the oil cylinder plunger and bleed pressure acted on and reach balance on the cylinder piston, pneumatic pump quit work automatically, reaches vapor liquid equilibrium.
The utility model has the advantages that the commutation gas signal of controlling two-position five-way double air controlled selector valve comes from source of the gas and directly inserts, thereby commutation flexibly; Two-position five-way double air controlled selector valve, pilot valve and cylinder body are mounted to one, thus compact structure, give to install, maintenance brings great convenience, open conduit wiring reduces, two-position five-way double air controlled selector valve adopts the pneumatic element universal product, reliable performance is easy to buying, the difficult leakage.
Below in conjunction with accompanying drawing the utility model is explained.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the pneumatic transfer fundamental diagram.
Embodiment:
By accompanying drawing as can be known, the utility model mainly comprises upper cylinder body 11, lower cylinder body 2, cylinder barrel 3, two-position five-way double air controlled selector valve 10, cylinder piston 6, cylinder piston rod 5 and overlaps two pilot valves 13,14 that 13-2, striker 13-1, spring 13-4, plug 13-5 and flower cover 14-2, striker 14-1, spring 14-4, plug 14-5 constitute by flower respectively.Upper cylinder body 11 and lower cylinder body 2 be placed in cylinder barrel 3 about, fixing by bolt 1.Two pilot valves 13,14 are respectively charged in upper cylinder body 11 and the lower cylinder body 2, and two-position five-way double air controlled selector valve 10 and lower cylinder body 2 are by interior hexagonal garden stud bolt and 11 board-like connections of upper cylinder body, and " O " RunddichtringO is adopted in each respective channel attachment portion sealing.Cylinder piston rod 5 belongs to motive sealing with lower cylinder body 2, realizes sealing by " O " RunddichtringO 15.External air source P is through two-position five-way double air controlled selector valve 10 communicate with upper and lower air chamber in the cylinder barrel 3 (seeing B among Fig. 3, A).Two pilot valves 13,14 are respectively equipped with source of the gas access port (seeing P2 among Fig. 3, P1) among the figure, the conduit 4 that is communicated with pilot valve links to each other with the control signal end K1 of two-position five-way double air controlled selector valve 10, is come out to be sent to the conduit of cylinder barrel 3 lower chambers on the sequence number 9 by two-position five-way double air controlled selector valve 10.When external air source entered lower chamber by two-position five-way double air controlled selector valve 10 outlet A, cylinder piston 6 moved up, and drives piston rod 5 simultaneously and moves up.When cylinder piston 6 collides pilot valve 13 strikers, this valve commutation, control signal P2 and K2 connect, make 10 commutations of two-position five-way double air controlled selector valve, at this moment external air source enters upper gas chamber B, makes cylinder piston 6 drive piston rod 5 and moves down, when cylinder piston collides pilot valve 14 strikers that are contained on the lower cylinder body, this valve commutation, 10 commutations of control two-position five-way double air controlled selector valve, to-and-fro motion so voluntarily.The big I of regulating input gas source and flow amount P realizes the frequent speed of piston rod movement.The big I of bleed pressure P realizes the size of piston rod ouput force.Sequence number 7,8,15,13-3,14-3 are " O " RunddichtringO among the figure, and sequence number 17 is a silencing apparatus.
