Background
The gas bleeding valve is a gas safety device used on gas pressure regulating equipment and has the function of overpressure bleeding and pressure stabilizing. When the outlet pressure of the gas pressure regulator rises and exceeds a set value of the bleeding pressure, the valve port of the bleeding valve is opened, gas is discharged, and safe gas utilization is guaranteed to meet the use requirements of users. The gas diffusion valve comprises a valve body with an air inlet and an air outlet, a valve port and a diaphragm are arranged in the valve body, a tray is arranged on the diaphragm, a spring and an adjusting nut are arranged on the tray, the diaphragm is connected with the top of the valve rod, and a valve core matched with the valve port is arranged at the bottom of the valve rod. When the outlet pressure of the gas pressure regulator is lower than the set value of the relief pressure, the spring on the diaphragm causes the valve core to close the valve port. When the gas pressure exceeds the set value of the diffusion pressure, the valve core is pushed to drive the valve rod to drive the diaphragm to move upwards to compress the spring, a gap is formed between the valve core and the valve port, and the gas is discharged from the gas outlet through the gap between the valve core and the valve port to implement diffusion. According to the gas diffusion valve, when the valve rod runs up and down, deviation is easy to occur, so that the adjustment precision is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a gas safety relief valve that deviation, regulation precision are high is difficult for appearing is provided.
In order to solve the technical problem, the utility model discloses a technical scheme does: the valve comprises a valve body, wherein an air inlet is formed in the bottom end of the valve body, an air outlet is formed in the side portion of the valve body, a bell-mouth-shaped valve port is formed in the lower portion of the valve body, a guide sleeve is arranged above the bell-mouth-shaped valve port, an adjusting spring is arranged in the guide sleeve, an adjusting nut in threaded connection with the inner wall of the valve body is arranged above the adjusting spring, a valve core matched with the bell-mouth-shaped valve port is arranged at the bottom of the guide sleeve.
The additional technical characteristics are as follows: the valve core is movably connected with the guide sleeve.
The utility model provides a gas safety relief valve according to the pressure requirement of diffusing, adjusts adjusting spring through adjusting the pressure mother. When the outlet pressure of the gas pressure regulator is lower than the set value of the diffusion pressure of the gas safety diffusion valve, the valve core closes the bell-mouth-shaped valve port. When the outlet pressure of the gas pressure regulator is higher than the set value of the diffusion pressure of the gas safety diffusion valve, gas enters the valve body from the gas inlet, the valve core is pushed to enable the valve core to move upwards to compress the adjusting spring, the valve core leaves the inner inclined plane of the bell-mouth-shaped valve port, a gap is formed between the valve core and the bell-mouth-shaped valve port, and the gas is discharged from the gas outlet through the gap between the valve core and the bell-mouth-shaped valve port, the first gas guide hole formed in the guide sleeve and the second gas guide hole formed in the adjusting nut to implement diffusion. When the outlet pressure of the gas pressure regulator is lower than the set value of the diffusion pressure of the gas safety diffusion valve, the gas pressure below the valve core is lower than the set value of the diffusion pressure, and the regulating spring pushes the valve core to move downwards until the valve core closes the bell-mouth-shaped valve port. The function of relieving overpressure and stabilizing pressure is realized.
The utility model provides a gas safety relief valve no longer uses diaphragm and valve rod, and the case is connected with the uide bushing, and the case is opened, is closed with horn mouth form valve port, has improved the sensitivity of safety relief valve. When the outlet pressure of the pressure regulating device exceeds a set value of the relief pressure, the pressure regulating device can be quickly relieved in time, and can quickly and automatically return to the seat after being repeatedly tripped, so that the safety gas utilization of the gas equipment is ensured. The device has the advantages of stable performance, high reaction speed, sensitive action, high discharge precision, tight closing, online adjustment, long service life, small volume, light weight, simple and compact structure and convenient installation and maintenance. The valve core is movably connected with the guide sleeve through threads, so that the valve core is convenient to replace.
