Description
Technical Field

Background
The proportional pressure reducing valve has simple structure, the valve body only has one movable part, namely the piston, and pressure difference is generated by utilizing the difference of the sectional areas of two ends of the piston to realize pressure reduction. The outlet pressure and the inlet pressure of the proportional pressure reducing valve are in a fixed proportional relation, and when no flow exists, the valve body is completely closed, so that static pressure reduction is realized. The proportional pressure reducing valve reduces pressure according to a fixed proportion, and the pressure behind the valve changes in proportion along with the pressure before the valve, so that the pressure cannot be adjusted.

In this embodiment, be equipped with rolling bearing in the box of the fluid speed measuring seal box behind the valve, the fluid speed measuring rolling wheel behind the valve rotates through rolling bearing and locates in the box of the fluid speed measuring seal box behind the valve, through setting up rolling bearing, can make the fluid speed measuring rolling wheel behind the valve more free rotation, the produced hindrance of reduction frictional force. Furthermore, a plurality of post-valve fluid speed measuring induction sheets are arranged on the wheel surface of the post-valve fluid speed measuring rotating wheel, and the plurality of post-valve fluid speed measuring induction sheets are distributed in an annular array by taking the rotating shaft of the post-valve fluid speed measuring rotating wheel as the center.
And the fluid pushing wheel behind the valve is in driving connection with the fluid speed measuring rotating wheel behind the valve through the power transmission mechanism behind the valve.
The operation of the proportional pressure reducing valve 10, which can monitor the fluid velocity before and after the valve, will be described below:
fluid with a certain flow rate enters the valve advancing water chamber 110, the fluid in the valve advancing water chamber 110 impacts the fluid blocking end 310 of the piston-type valve flap 300, and the fluid blocking end 310 presses the elastic resetting member 400 to be elastically deformed when the fluid impacts the fluid blocking end 310;
when the elastic restoring member 400 is elastically deformed, the fluid blocking end 310 is separated from the valve flap blocking ring 120, so that the fluid enters the fluid decompression chamber 320 of the piston-type valve flap 300 through the fluid blocking hole 121, and then enters the post-valve outlet chamber 210 from the fluid decompression chamber 320;
when the fluid stops entering the pre-valve water outlet chamber 110, the fluid blocking end 310 of the piston-type valve flap 300 is no longer impacted by the fluid, and the elastic restoring member 400 will restore the elastic deformation, so that the fluid blocking end 310 will engage with the flap blocking ring 120 and block the fluid blocking hole 121, and the fluid cannot enter the fluid pressure reducing chamber 320 and the post-valve water outlet chamber 210;
during the process that fluid with a certain flow rate enters the pre-valve water cavity 110, the fluid in the pre-valve water cavity 110 drives the pre-valve fluid pushing wheel 510 to rotate, and the pre-valve fluid pushing wheel 510 further drives the pre-valve fluid speed measuring rotating wheel 532 to rotate through the pre-valve power transmission mechanism 520;
when the fluid speed is faster, the rotational speed of the fluid before the valve pushing wheel 510 is faster correspondingly, so that the rotational speed of the fluid before the valve measuring rotating wheel 532 is faster; when the fluid speed is slower, the rotational speed of the pre-valve fluid pushing wheel 510 is correspondingly slower, so that the rotational speed of the pre-valve fluid speed measuring rotating wheel 532 is slower;
it can be known that the fluid speed in the pre-valve water feeding cavity 110 can indirectly react to the pre-valve fluid speed measuring rotary wheel 532 through the pre-valve fluid push wheel 510, and since the pre-valve fluid speed measuring rotary wheel 532 is provided with the pre-valve fluid speed measuring sensing piece 535 on the wheel surface, when the pre-valve fluid speed measuring sensing piece 535 passes through the pre-valve fluid speed measuring sensor 533 each time, the pre-valve fluid speed measuring sensor 533 can count for one time correspondingly, so as to calculate the current fluid speed in the pre-valve water feeding cavity 110;
similarly, the fluid velocity in the post-valve outlet chamber 210 can also be monitored using the post-valve flow rate monitoring device 600;
when the fluid speed in the pre-valve water cavity 110 does not need to be measured, the pre-valve fluid speed measuring sensing piece 535 is abutted by the pre-valve fluid speed measuring sensing piece 534 by screwing the pre-valve rotating wheel locking bolt 534, the pre-valve fluid speed measuring sensing piece 535 is limited by the pre-valve rotating wheel locking bolt 534 to drive the pre-valve fluid speed measuring rotating wheel 532 to stop rotating, and the pre-valve fluid speed measuring rotating wheel 532 which stops rotating also indirectly drives the pre-valve fluid pushing wheel 510 to stop rotating.
The structural design principle of the pre-valve flow rate monitoring device 500 is explained below:
1. by providing the pre-valve fluid push wheel 510 within the cavity of the pre-valve water cavity 110, the pre-valve fluid push wheel 510 can sense the velocity of the fluid in real time and react the change in the velocity of the fluid to the pre-valve fluid velocity measurement mechanism 530 via the pre-valve power transmission mechanism 520;
2. by arranging the before-valve fluid speed measuring seal box 531, the before-valve fluid speed measuring rotary wheel 532 is placed in the before-valve fluid speed measuring seal box 531, so that the influence of external factors on the before-valve fluid speed measuring rotary wheel 532 can be reduced, the before-valve fluid speed measuring rotary wheel 532 rotates more stably, and the accuracy of the rotating speed of the before-valve fluid speed measuring rotary wheel 532 is improved;
3. the fluid tests the speed and is equipped with the fluid and tests the speed response piece 535 before the valve on the wheel face of the fluid wheel 532 before the valve, and the fluid tests the speed response piece 535 can play the effect in following two aspects simultaneously before the valve: on one hand, the pre-valve fluid velocity measurement sensing chip 535 may cooperate with the pre-valve fluid velocity measurement sensor 533 to calculate the current fluid velocity in the pre-valve water cavity 110; on the other hand, the pre-valve fluid velocity measurement sensing piece 535 can be matched with the pre-valve fluid velocity measurement driving wheel locking bolt 534, when the fluid velocity in the pre-valve water cavity 110 does not need to be measured, the pre-valve fluid velocity measurement driving wheel locking bolt 534 is screwed, so that the pre-valve fluid velocity measurement driving wheel locking bolt 534 is abutted against the pre-valve fluid velocity measurement sensing piece 535, the pre-valve fluid velocity measurement sensing piece 535 is limited by the pre-valve fluid velocity measurement driving wheel locking bolt 534 to enable the pre-valve fluid velocity measurement driving wheel 532 to stop rotating, and the pre-valve fluid velocity measurement driving wheel 532 which stops rotating also indirectly enables the pre-valve fluid pushing wheel 510 to stop rotating;
4. the front valve fluid speed measuring sensor pieces 535 are arranged on the wheel surface of the front valve fluid speed measuring rotating wheel 532, and due to the structural design, the front valve fluid speed measuring sensor pieces 535 can enable the front valve fluid speed measuring rotating wheel locking bolts 534 to easily enter a gap between two adjacent front valve fluid speed measuring sensor pieces 535, so that the front valve fluid speed measuring rotating wheel 532 can be timely and stably locked.
According to the proportional pressure reducing valve 10 capable of monitoring the fluid speeds before and after the valve, the front valve body 100, the rear valve body 200, the piston type valve clack 300 and the elastic resetting piece 400 are arranged, particularly, the flow speed monitoring device 500 before the valve and the flow speed monitoring device 600 after the valve are optimally designed, the fluid speeds before and after the valve are monitored in real time, accidents are effectively prevented, and the water safety of production and life is ensured.
