Abstract

The utility model relates to a pedal pneumatic controller for a valve, which comprises a pneumatic device, a connecting arm, a screw rod, a slot arm, a pedal switch and a fixing plate. An air inlet end of the pneumatic device is connected with an air outlet of the pedal switch through an air tube. A piston rod of a cylinder is fixedly connected with one end of the connecting arm, and the other end of the connecting arm is fixedly connected with the screw rod. The middle part of the slot arm is provided with a slot, and the screw rod can slide in the slot. One end of the slot arm is fixedly connected with a valve rod of a valve. The pneumatic device and the valve are fixed on the fixing plate. The utility model adopts a pedal switch to control the action of the pneumatic device, and the connecting arm which is connected with a piston rod of the pneumatic device is driven by the straight reciprocating motion of the piston rod to move linearly. The screw rod on the end of the connecting arm slides in the slot arm to drive the slot arm to rotate axially around the central axis of the valve rod of the valve which is connected with the slot arm. Therefore, the opening or the closing of the valve is realized. After the valve adopts the structure to control a paint spraying device, a user can easily control the paint spraying device by only stepping the pedal switch.

Description

Valve is ridden air control unit

Technical field

The utility model relates to a kind of control device, concretely, relates to the foot-operated air control unit of a kind of valve.

Background technology

Valve on the spray-painting plant of the prior art is generally manual control, and when spraying paint, the user must manually move tap wrench at every turn, such tap wrench of moving repeatedly, and very effort is unfavorable for long-time operation.

Summary of the invention

The purpose of this utility model is to overcome the technical problem that exists in the prior art, provides a kind of by foot-operated control pneumatic means, the foot-operated air control unit of the valve of valve on the control spray-painting plant.

For achieving the above object, the foot-operated air control unit of valve of the present utility model comprises pneumatic means, linking arm, screw rod, groove arm, pedal switch, pneumatic means fixed head; The inlet end of described pneumatic means links to each other with the gas outlet of described pedal switch, the piston rod of described cylinder and described linking arm one end are connected, and the linking arm other end and described screw rod are connected, and described groove arm is provided with groove, described screw rod can slide in described groove, and groove arm one end and valve rod are connected; Described pneumatic means and valve are fixed on the pneumatic means fixed head.

The utility model adopts the action of floor push control pneumatic means, and the piston rod straight reciprocating motion by pneumatic means drives the linking arm rectilinear motion that is attached thereto, making the screw rod of linking arm end slide to drive the groove arm in the groove arm serves as that axle rotates with the central shaft of coupled valve rod, thereby realizes the unlatching of valve or close.Adopt the valve of this kind structure control spray-painting plant, the controlled valve of need not the operator requiring great effort only needs a pushes pedals switch to control easily spray-painting plant.

Features and applications of the present utility model will be described further in conjunction with the accompanying drawings by the specific embodiment.

Description of drawings

Fig. 1 is the closed condition figure of the foot-operated air control unit of valve of the present utility model.

Fig. 2 is the opening figure of the foot-operated air control unit of valve of the present utility model.

Fig. 3 is the vertical view of the foot-operated air control unit of valve of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 3, the foot-operated air control unit of the valve in this specific embodiment comprises pedal switch 1, cylinder 2, U type linking arm 3, screw rod 4, groove arm 5, air cylinder fixed plate 6, pedal switch 1 is provided with air inlet 101, gas outlet 102, and cylinder 2 is provided with piston rod 201, and the groove arm is provided with groove 501; Pedal switch links to each other by tracheae with the air inlet/outlet of cylinder, the end of cylinder piston rod 201 welds mutually with the arc tips of U type linking arm 3, the openend of U type linking arm is provided with hole 301, groove arm 5 is provided with groove 501, screw rod 4 shafts pass the groove 501 that the hole 301 on the U type linking arm reaches between U type linking arm openend, and the bar head is fixed on the U type linking arm openend lateral surface with nut; The groove arm at one end is provided with hole 502, and valve 7 is provided with valve rod 701, and stem head passes described hole 502, and on stem head fastening nut; Cylinder and valve body all are fixed on the air cylinder fixed plate.

Fig. 1,2 are respectively the unlatching that this reality is the foot-operated air control unit of valve of mode, and closure state figure briefly describes the course of work of this specific embodiment with reference to the accompanying drawings.Be that pedal switch is given gas at first by air inlet pipe and air inlet, when stepping on pedal switch, the cylinder air feed is given by tracheae in gas outlet 102, piston rod 201 outwards moves, and the U type linking arm that promotes to be attached thereto moves, behind the U type linking arm setting in motion, being fixed in its terminal screw rod will be slided to an end that links to each other with valve rod by the end of groove 501, increase along with the piston rod displacement, the displacement of the screw rod 4 of U type linking arm end in groove 501 increases, and to drive groove arm 5 serve as that axle rotates with the central shaft of valve rod, rotates thereby drive coupled valve rod, realizes the unlatching of valve; The process of valve closes is similar to the above process, and just direction is opposite.

Described air cylinder fixed plate should be installed in position, is in the dead-centre position to avoid linking arm mechanism.

The above-mentioned specific embodiment is a kind of optimal way of the present utility model, should illustrate, originally is existing in this mode with novel never office; all are by pedal switch, pneumatic means, groove arm; screw rod, the control device that linking arm is formed all should fall within the protection domain of the present utility model.
