Abstract
The invention discloses a novel safety valve. A piston is arranged in an inner cavity of a valve body; a spring is arranged and pressed above the piston from an upper cavity of the valve body; an upper proximity sensor is arranged on a valve cover; and the valve cover is arranged and fixed on the valve body by using bolts. The advantages are that: the novel safety valve has a simple structure, is used for detecting and controlling the leakage of a pneumatic or hydraulic actuator in a pneumatic or hydraulic pipeline system, and can effectively overcome the defects that a method adopting schedule maintenance or preservation frequently cannot solve existing problems effectively in time because of inevitable careless mistakes or other reasons, and a method adopting a monitoring sensor causes the problems that the whole system is complex, the cost is high and the installation and maintenance costs are high.
Description
Technical field
The present invention relates to a kind of safety valve, refer in particular to be installed on pneumatic or hydraulic plumbing system in be used to detect pneumatic or whether hydraulic actuator produces leakage, and can make a kind of New-type safety valve of corresponding control to described executive component, belong to the mechanical part technical field.
Background technique
In pneumatic or hydraulic system, pneumatic or hydraulic actuator takes place to leak the waste that not only can cause the energy, also can cause corresponding security incident and some other corresponding accident simultaneously thus.Containment measures to pneumatic or hydraulic actuator, mainly be to adopt two kinds of ways at present: for general low gear item, leak can not cause serious consequence to safety or other situation or the pneumatic hydraulic executive component be installed on the check point that is easy to of entire equipment, the way that then adopts time-based maintenance to safeguard; Be not easy to check point and can cause serious consequence or be installed on entire equipment for the pneumatic hydraulic executive component for high end equipment or leakage, side adopts the mode of corresponding monitoring sensor to monitor or controls.
In two kinds of above-mentioned methods, though adopt the method for periodic maintenance or maintenance simple to operate, owing to will so have inevitably carelessness or other reason, often can not solve the problem that exists timely and effectively by artificial execution.Though and the method automaticity of employing monitoring sensor is higher,, whole system is complicated, and cost is higher, and the I﹠M cost is higher.
Summary of the invention
The objective of the invention is to: provide a kind of being installed on to be used to detect pneumatic in pneumatic or the hydraulic plumbing system or whether hydraulic actuator produces a kind of element that leaks and can make corresponding control to described executive component.Overcome the method that adopts periodic maintenance or maintenance in the existing technology, owing to having inevitably carelessness or other reason, often can not solve existing problems timely and effectively, and the method that adopts monitoring sensor, the whole system of being brought is complicated, cost is higher, a kind of New-type safety valve of the defective that I﹠M is higher.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of New-type safety valve, it is made up of valve body, piston, spring, valve gap, bolt, proximity detector, have fluid inlet a and outlet b on the described valve body, described piston is installed in the valve body chamber, have damping hole c on the described piston, the diameter of damping hole c is less than the fluid inlet a diameter of opening on the valve body.Piston is divided into two parts with the valve body chamber, and on piston top, the part that promptly has fluid output on the valve body is installed pressure spring.Opening part at valve body is provided with valve gap, and described valve gap is fixed by bolts to the opening part of valve body, and proximity detector is installed above the valve gap.During use the outlet on the valve body is linked to each other with pneumatic or hydraulic actuator, import on the valve body is linked to each other with source of the gas or hydraulic power, its working principle is: the import from the valve body of the air pressure of certain pressure or hydraulic pressure, enter the cavity of resorption of valve body, because the damping hole on the piston is than little many of the import on the valve body, so there is certain pressure difference the both sides of piston, at this moment, piston just rises under action of pressure, the elastic force of pressure difference and spring when rising to a certain degree, pressure in the pneumatic or hydraulic actuator reaches balance, so piston just keeps stable state of equilibrium, fluid is through import, damping hole, outlet enters pneumatic or hydraulic actuator, and when pneumatic or hydraulic actuator take place to leak, pressure in the then pneumatic or hydraulic actuator reduces or is zero, destroyed in above-mentioned state of equilibrium, piston just continues upwards in existing position, until piston sealing is blocked in outlet, simultaneously, because the rising of piston enters the detection action radius of proximity detector, so proximity detector will send the corresponding instruction signal, control corresponding executive component equipment is carried out control corresponding.
The invention has the beneficial effects as follows: simple in structure, the Leak testtion of pneumatic or hydraulic actuator that is used for pneumatic or hydraulic plumbing system is in control, can effectively overcome the method that adopts periodic maintenance or maintenance, owing to having inevitably carelessness or other reason, often can not solve existing problems timely and effectively, and the method that adopts monitoring sensor, the whole system of being brought is complicated, cost is higher, the defective that I﹠M is higher.
