Detailed Description
An adjusting exhaust valve comprises a valve body 1, a valve cover 9 and a valve core 2, wherein the valve body 1 and the valve cover 9 are in threaded connection to form a valve cavity 1-1 inside, the bottom of the valve body 1 is provided with a lower through hole 1-2 communicated with the valve cavity 1-1, the side wall of the valve body 1 is provided with a plurality of side through holes 1-3 communicated with the valve cavity 1-1, the valve core 2 is of an inverted T-shaped structure, the valve core 2 is movably arranged in the valve cavity 1-1 up and down, the valve core 2 is sleeved with a sealing seat 4, the sealing seat 4 is sleeved with a sealing gasket 3, the valve cavity 1-1 is internally provided with a positive pressure spring 7 and a spring gasket 8, the lower end of the positive pressure spring 7 is pressed on the sealing seat 4, the upper end of the positive pressure spring is pressed on the spring gasket 8, the valve rod 2-1 of the valve core 2 is sleeved with, The lower end of the valve seat is pressed against the sealing seat 4, the clamp spring 6 is clamped on the valve rod 2-1, the valve cover 9 is in threaded connection with an adjusting rod 10, and the inner end of the adjusting rod 10 extends into the valve cavity 1-1 to drive the spring gasket 8 to move downwards.
The utility model discloses install on jar body, jar internal pressure is too high, overcomes malleation spring 7 elasticity, and the working medium is upwards backed up seal receptacle 4 from lower through-hole 1-2 to discharge by side through-hole 1-3.
When negative pressure occurs, the valve core 2 moves downwards for a certain distance by overcoming the elasticity of the negative pressure spring 5, and outflow gas enters the valve cavity 1-1 from the side through hole 1-3 and then enters the tank body from the plane hole 4-1 on the sealing seat 4.
The plane hole 4-1 is arranged on the sealing seat 4 in a vertically through way, and under the positive pressure condition, the plane hole 4-1 is sealed by the sealing valve disc 2-2 at the lower part of the valve core 2.
When the positive pressure is used, the pressure can be adjusted (the pressure in the positive pressure can be adjusted by rotating the adjusting rod 10 and pressing the positive pressure spring 7 through the spring gasket 8). The pressure value is checked by the manometer to the required pressure of adjustment, and the pressure regulating is adjusted by adjusting pole 10 screw thread, and clockwise rotation adjusts pole 10, and pressure increases, and anticlockwise rotation adjusts pole 10, and pressure reduces. The negative pressure can not be adjusted, is determined by the elasticity of the negative pressure spring 5, is set when leaving a factory, and has the negative pressure within 0.01 MPA.
The outer end of the adjusting rod 10 is integrally formed to be a rotating disc 10-1.
The lower end face of the valve body 1 is provided with a sealing groove 1-4, and the sealing groove 1-4 and the lower through hole 1-2 are concentrically arranged.
