Description
Technical field
The utility model relates to a kind of lock-up valve.
Background technique
When the instrument air system broke down, lock-up valve can cut off the passage of regulator and valve automatically, makes valve remain on the origin-location; To guarantee normally carrying out of manufacturing process, after air failure is eliminated, recover proper functioning; Lock-up valve is applicable in the important automatic control loop as safety protection device, and on the market lock-up valve at present, it is not ideal enough that its structure is provided with; The effect of being played is stable inadequately; Effect is obvious inadequately, can't well guarantee normally carrying out of manufacturing process, and important automatic control loop is not had good safety protection.
Summary of the invention
The purpose of the utility model is to overcome the defective of existing technology, provides a kind of internal structure setting more reasonable, more reliable, the lock-up valve that safety protection function is higher.
For realizing above-mentioned purpose, the utility model adopts a kind of lock-up valve, comprises upper valve body, middle valve body, following valve body, spool, pressure-regulating device, middle diaphragm, following diaphragm, adjustable lever; Said pressure-regulating device comprises screw press, pressure adjusting spring, look nut and voltage regulation diaphragm, and said screw press runs through and is axially disposed within on the upper valve body, and look nut is arranged in the inner chamber of upper valve body and is fixedly connected with screw press; The upper-end surface of valve body during voltage regulation diaphragm is arranged on; The bottom of said screw press and the upper-end surface of voltage regulation diaphragm are provided with a steel ball, being set on the screw press of pressure adjusting spring, and an end withstands the upper wall of upper valve body; The upper-end surface of valve body was provided with during the other end held out against; On the intermediate throughholes of valve body, said spool was arranged on down the bottom of valve body under adjustable lever was axially disposed within, and the top of spool contacts with the bottom of adjustable lever.
The utility model further is provided with again; Upper valve body, middle valve body and following valve body jack shaft are to forming the through hole of always wearing; The said bilateral symmetry of valve body down is provided with access port and delivery outlet; Diaphragm arrangement is between middle valve body and voltage regulation diaphragm in said, and following diaphragm arrangement is between middle valve body and following valve body.
The utility model further is provided with again; Valve body is provided with a ventilation inclined hole and an aperture in said; Form a cavity in said between valve body and the voltage regulation diaphragm, between said upper valve body and screw press, between steel ball and the voltage regulation diaphragm, between voltage regulation diaphragm and the middle valve body, being connected between the end face, being provided with the O RunddichtringO between the top end of the bottom of adjustable lever and spool of middle valve body and adjustable lever.
In sum, the beneficial effect of the utility model is: signal gets into from interface, during aperture through middle valve body and inclined hole get in the cavity of valve body and voltage regulation diaphragm formation; Move up because compressed-air actuated effect promotes voltage regulation diaphragm, pressurized air is got in O type closed hole, depress down diaphragm promotion valve rod and open spool; Access port and delivery outlet form path like this, after the Signal Compression air cuts off, because the Signal Compression air is released the pressure of following diaphragm; The Returnning spring at spool place makes valve core reset, and access port and delivery outlet open circuit, through above setting; Make that the internal structure setting of lock-up valve is more reasonable; The function of product is more reliable, can better guarantee normally carrying out of technological process, and control loop is had a good safety protection effect.
