Abstract
The utility model relates to the technical field of valves, in particular to a novel air constant pressure valve. The novel air constant pressure valve is characterized in that the upper end of an air valve body is rotationally connected with an air valve exhaust cover; a sealing column is arranged at the center in the air valve body; a sealing gasket is connected between the lower end of the sealing column and the interior of the air valve body in a sleeving mode; springs are connected outside the middle portion of the sealing column in a sleeving mode; and the upper end of the springs is provided with a spring baffle block which is externally connected with the upper end of the sealing column in a sleeving mode. The novel air constant pressure valve has following beneficial effects: the novel air constant pressure valve is simple in structure, reasonable in design and convenient in operation; the exhaust cover at the upper end of the constant pressure valve is of an arc structure so that air can be well circulated when being exhausted, resulting in a fine muting effect during an air-exhausting process; and control on the internally-arranged spring baffle block is achieved by rotating the exhaust cover at the upper end by the air constant pressure valve so that control on elasticity of the integrally-arranged springs is achieved, thus adjusting the constant pressure valve without detachment.
Description
Technical field:
The utility model relates to valve technology field, is specifically related to a kind of novel air constant pressure valve.
Background technique:
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.Various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Constant pressure valve in use, adopt screw to carry out the spring of control valve inside, thereby carry out the size of modulating valve internal air pressure, if inner air pressure surpasses constant air pressure, gas can back down the sealing column of valve inside, overflow valve body, thereby realize the effect of constant voltage, existing constant pressure valve, when utilizing screw control spring, need to disassemble constant pressure valve from product, then carry out screw adjusting, operation is very inconvenient like this, and validity does not reach requirement, simultaneously existing constant pressure valve when Exhaust Gas owing to be directly discharge, therefore can produce very large noise.
Model utility content:
The purpose of this utility model is to provide a kind of novel air constant pressure valve, it is simple in structure, reasonable in design and easy to operate, the exhaust cap of constant pressure valve upper end is designed to arc structure, when exhaust, gas can well circulate like this, thereby during exhaust, reach good muting function, constant pressure valve is controlled inner spring block by the exhaust cap of rotation upper end simultaneously, thereby controls the elastic force of contained spring, and constant pressure valve also can be regulated in the situation that not dismantling.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises air valve body 1, air valve exhaust cap 2, sealing column 3, spring block 4, spring 5, gasket seal 6, seal ring 7 and exhaust port 8, the lower end of air valve body 1 is provided with seal ring 7, the upper end of air valve body 1 is connected with air valve exhaust cap 2, the inside, outside of air valve exhaust cap 2 is provided with several exhaust ports 8 uniformly, the inside center of air valve body 1 is provided with sealing column 3, between the inside of the lower end of sealing column 3 and air valve body 1, be socketed with gasket seal 6, the outside, middle part of sealing column 3 is socketed with spring 5, the upper end of spring 5 is provided with spring block 4, and spring block 4 is socketed in the outside, upper end of sealing column 3.
The upper end of described air valve exhaust cap 2 is set to arcuate structure.
The utility model working principle: the lower end of air valve body 1 utilizes seal ring 7 and tracheae to be tightly connected, and when the gas atmosphere of tracheae inside is identical with the setting value of constant pressure valve, all parts of constant pressure valve inside is state of rest; When the gas atmosphere of tracheae inside is too high, gas can upwards push up the sealing column 3 of air valve body 1 inside, sealing column 3 and gasket seal 6 are separated, thereby gas is discharged, and be drained in atmosphere by the exhaust port 8 in air valve exhaust cap 2 outsides, until the air pressure of tracheae inside and setting value maintain an equal level, exhaust port 8 designs simultaneously, at the circular arc side of air valve exhaust cap 2, are difficult for being stopped by foreign object when exhaust.
The air valve exhaust cap 2 of constant pressure valve can be carried out clockwise and is rotated counterclockwise, when air valve exhaust cap 2 turns clockwise, air valve exhaust cap 2 drives inner spring block 4 to move downward, thereby strengthen the elastic force of spring block 4 lower end springs 5, when spring 5 elastic force increase, increase the pressure of air pressure inside, otherwise fallen hypobaric pressure.
The utlity model has following beneficial effect: it is simple in structure, reasonable in design and easy to operate, the exhaust cap of constant pressure valve upper end is designed to arc structure, when exhaust, gas can well circulate like this, thereby during exhaust, reach good muting function, constant pressure valve is controlled inner spring block by the exhaust cap of rotation upper end simultaneously, thereby the elastic force of controlling contained spring also can regulate constant pressure valve in the situation that not dismantling.
