Abstract
The utility model relates to a valve, particularly a voltage stabilization adjustor which makes use of a mechanical valve to control gas pressure to achieve the purpose of stabilizing voltage. The voltage adjustor comprises a valve body, a valve seat, and a spring which is installed in the valve seat. An air inlet port and an air exhaust port are arranged in the valve seat. The utility model is characterized in that a block of diaphragm which can lead the air inlet port and the air exhaust port to be mutually separated is arranged between the valve body and the valve seat. The upper surface of the diaphragm contacts the spring. The lower surface of the diaphragm is stuck on the air inlet port or / and the air exhaust port under the action of the spring. The utility model has the advantage of simple structure.
Description
The utility model relates to a kind of valve, specifically a kind ofly utilizes mechanical valve to come control gaseous pressure, reaches the voltage regulation adjustor of voltage stabilizing purpose.
In the gas application field, the quality of gaseous mass more and more is subjected to everybody attention, and whether stablizing of gas pressure directly has influence on the quality of product.Primary component as control gaseous pressure---voltage regulation adjustor is a kind of very important device.In the prior art, a kind of safety valve commonly used is controlled, and its defective is that effect is undesirable; Also the someone adopts solenoid valve to come the air pressure of control gaseous, and its deficiency is manufacture cost height, complex structure, easy break-down, and the user is difficult to maintenance or renewal part.
I had once designed a kind of voltage regulation adjustor of fully-machinery type, utilize steel ball to make valve, whole valve divides upper, middle and lower 3 air cavitys, the middle part air cavity is mainly used in and lifts valve rod, opens the bottom valve, make lower stream of airflow enter bottom and top air cavity by the steel ball valve port, the top air cavity is used for gas storage and voltage stabilizing, and unnecessary pressed gas is discharged smoothly, enter the actuator of control source of the gas, realize voltage stabilizing.But because this structure more complicated, thereby volume is bigger, and the manufacturing trouble, cost is higher.
The purpose of this utility model is a kind of simple in structure, manufacturing of design and easy for installation, cheap board-like voltage regulation adjustor.
Its main technical schemes comprises valve body, valve seat and installation spring within it, suction port and relief opening are set in valve seat, it is characterized in that valve body and valve base chamber have one with suction port and relief opening diaphragm spaced apart from each other, top and the spring of diaphragm contacts, and the following of diaphragm is attached to suction port or/and on the relief opening under the effect of spring.
Its another feature is at the two ends of spring the spring seat of honour and spring lower seat to be arranged respectively, and wherein, spring lower seat contacts with diaphragm, the spring seat of honour and a following end in contact that is connected the adjusting bolt of valve body upper end.
On the adjusting bolt, nut and stiffnut are arranged; Bottom at valve body is provided with vent; The annular flow path that has a circle to open wide on the top of suction port, the lower end of suction port and the lower end of relief opening all are positioned at the bottom of valve seat.
The utility model has the advantages that because the through and off of suction port and relief opening are controlled by diaphragm and spring, when suction pressure during greater than spring pressure, suction pressure backs down diaphragm, suction port directly is communicated with relief opening, the air-flow conducting, when suction pressure during less than spring pressure, diaphragm is close on the relief opening, and suction port and relief opening are separated, and has blocked the circulation of air-flow, thereby realized the purpose of adjustments of gas pressure, this structure and the original steel ball that utilizes back down piston, and suction port is compared with the mode of relief opening break-make, and it is much simple that its structure is wanted, manufacturing is more convenient, and the possibility that breaks down is also smaller; Secondly, behind the bolt that has connected a Regulation spring preload pressure on the valve body, setting spring pretightening force as required, so that obtain different gas pressures, when the spring force of setting was big, corresponding suction port pressure was also big, vice versa.
Fig. 1 is a structural drawing of the present utility model.
As shown in the figure: valve body 4 utilizes screw 12 to interconnect with valve seat 13, and diaphragm 11 is set betwixt, in valve seat 13, have separately respectively and go up, the suction port 10 and the relief opening 14 of following perforation, when diaphragm is attached on the relief opening 14, just relief opening 14 and suction port 10 are separated, the annular flow path that the top of suction port 10 has a circle to open wide, so that diaphragm 11 can be controlled the break-make of suction port 10 and relief opening 14 better, on the inner chamber 7 of valve body 4, following two ends have the spring seat of honour 5 and spring lower seat 9 respectively, spring 6 is positioned on the spring, following seat 5, between 9, spring lower seat 9 wherein is close on the diaphragm 11, diaphragm 11 can be pressed on the relief opening 14, the upper end at the spring seat of honour 5 contacts with the adjusting bolt 1 that a utilization is threaded in valve body 4 upper ends, on adjusting bolt 1, nut 2 and stiffnut 3 are arranged, wherein nut 2 is used for after regulating suitable spring pressure, to regulate bolt locking, stiffnut 3 is actual to be the bolt of a middle part band screw, regulating bolt 1 cooperates with the screw of this nut 3, can avoid like this because of using the adjusting bolt to damage valve body repeatedly, the vent 8 that a communication with cavity 7 and atmosphere are arranged in the bottom of valve body 4 is so that guarantee that diaphragm can move under free state.
