Abstract
The utility model discloses an use gas accuse valve of cylinder as execute component, make the cylinder of reciprocating action including valve body, valve rod and control valve rod, the cylinder is on by the fixed valve body of support, and valve rod one end links to each other with piston rod of the cylinder, is equipped with reset spring in the working chamber of cylinder, and another working chamber communicates with each other through trachea and control gas circuit, and the gas vent that is equipped with reset spring's working chamber in the cylinder has intake pipe and control gas circuit to communicate with each other, is equipped with pressure relief valve in the intake pipe. Incline through the reset spring at the cylinder and let in the steady pressure air supply, can increase the effort of reset spring to cylinderpiston to solve the not enough valve bite problem that causes of spring force, make the operation that the valve can be smooth and easy, eliminate the potential safety hazard.
Description
Technical field
The utility model relates to Air control valve, specifically a kind of gas control taking cylinder as executive componentValve.
Background technology
Conventionally the valve using cylinder as executive component is a kind of single-acting valve, controls source of the gas and gasWorking chamber of cylinder communicates, the piston rod of the cylinder action of stretching or contract in the time that compressed air enters working chamber,The valve rod that drive is attached thereto enters or moves back, thus the unlatching of by-pass valve control or close. In Chemical Manufacture,Often there will be the instrument air fault cannot air feed or electric fault cannot power time, need valve inAbort situation (standard-sized sheet or complete shut-down), to ensure the safety of Chemical Manufacture. But, in actual production processIn, due to reasons such as valve control medium and valve service lives, such as answering in executive component cylinderPosition spring is long-term there is flexibility decrease after using, or the parts such as valve rod or spool get rusty, or because mixingThe many factors such as thing obstruction, often there will be valve bite, and valve cannot normally complete conditioned disjunction standard-sized sheetComplete shut-down operation, brings potential safety hazard to production. This just needs an interim processing scheme to ensure rawProduce stable. The present invention can solve the valve bite problem that spring force deficiency causes, and makes the valve can be suitableSmooth operation.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of taking cylinder as carrying out unitThe Air control valve of part, can avoid valve to occur bite phenomenon, eliminates safe hidden trouble.
For achieving the above object, the utility model has adopted following technical scheme: comprise valve body, valve rodWith control valve rod and make the cylinder of reciprocating action, cylinder is by support fixed valve body, valve rod one end and cylinderPiston rod is connected, and in a working chamber of cylinder, is provided with back-moving spring, and another working chamber passes through tracheaeCommunicate with controlling gas circuit, the exhaust outlet that the working chamber of back-moving spring is housed in cylinder has air inlet pipe and controlGas circuit communicates, and pressure relief valve is housed in air inlet pipe.
Further, in the air inlet pipe communicating with the working chamber exhaust outlet that back-moving spring is housed in cylinder, fillThere is vacuum filter.
Preferably, back-moving spring is arranged in the cylinder working chamber with the reverse side of valve rod.
The beneficial effects of the utility model are: pass into steady pressure by the back-moving spring side at cylinderSource of the gas, can increase the active force of back-moving spring to cylinder piston, causes thereby solve spring force deficiencyValve bite problem, valve can be operated smoothly, eliminate safe hidden trouble.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is carried out clearly and completelyDescribe.
As shown in Figure 1, the utility model comprises valve body 1, valve rod 3 and controls valve rod 3 and do toward double actionThe cylinder 4 of doing, cylinder 4 is by support 2 fixed valve bodies 1, valve rod 3 one end and cylinder 4 piston rodsBe connected. Cylinder inner cavity is divided into two working chambers, one of them working chamber by piston 41 in cylinder 4In 43, be provided with back-moving spring 42, another working chamber 44 communicates with controlling gas circuit by tracheae 45, gasThe exhaust outlet that the working chamber 43 of back-moving spring 42 is housed in cylinder 4 has air inlet pipe 46 to pass through vacuum filter5 communicate with controlling gas circuit, and pressure relief valve 6 is housed in air inlet pipe 46.
In this example, back-moving spring 42 is arranged in the working chamber 43 with the reverse side cylinder of valve rod 2.
Its operation principle is as follows: as shown in Figure 1, valve is in closed condition, and compressed air is through decompressionFilter 5, air inlet pipe 46 are delivered to the working chamber 43 at back-moving spring 42 places, with back-moving spring 42Keep together the pressure downward to piston 41. Control the work that gas circuit is transported to back-moving spring 42 placesCompressed air pressure in chamber 43 is less than the air pressure being delivered in working chamber 44.
In the time that needs are opened valve, control gas circuit is transported to compressed air the work of cylinder by tracheae 45Do in chamber 44, promotion piston 41 is up and back-moving spring 42 is compressed to the gas in working chamber 43Pressure raises, and is discharged through pressure relief valve 6 by air inlet pipe 46. Meanwhile, piston 41 drives phase with itThe valve rod 2 connecting is up, valve open, and medium passes through valve body 1 along the direction of arrow. Otherwise, reset bulletThe downward release pressure of spring 42 resets, simultaneously by control compressed air that gas circuit carries through vacuum filter 5,Air inlet pipe 46 is delivered to the working chamber 43 at back-moving spring 42 places, promotes together with back-moving spring 42Piston 41 is descending, drives the valve rod 3 being attached thereto to move downwards, valve-off.
