DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0039] See also Figures 1 to 4 The height valve 200 test device 100 includes a test seat 1, a drive assembly 2 and a pneumatic assembly; the test seat 1 includes a base 11 and a bracket 12, the side of the base 11 located in the thickness direction is the installation side 111, the bracket 12 is arranged on the installation side 111, and is formed with a first installation rod 121 and a second installation rod 122 which are arranged at intervals with the installation side 111 and extend along the length direction of the base 11, the first installation rod 121 and the second installation rod 122 are arranged at intervals along the width direction of the base 11, and the first installation rod 121 is provided with a first installation block 13 movable along the length direction of the base 11, and the second installation rod 122 is provided with a second installation block 14 movable along the width direction of the base 11; the drive assembly 2 includes a first drive shaft 21, and a first transmission member 22 drivingly connected to the first drive shaft 21, the first drive shaft 21 revolves around the first drive shaft 21 located in the thickness direction of the base 11 The upward axis rotation is arranged on the installation side 111 and is arranged corresponding to the first installation rod 121. The first transmission member 22 is transmission-connected with the first installation block 13 to convert the rotation of the first drive shaft 21 into the movement of the first installation block 13 along the length direction of the base 11, wherein one of the first installation block 13 and the second installation block 14 is used to fix the valve body 210 of the height valve 200, and the other is used to fix the rocker rod 220 of the height valve 200, so that when the first installation block 13 moves along the length direction of the base 11, the valve body 210 and the rocker rod 220 can move relative to each other; the pneumatic component includes a gas supply tank for providing an air source to the height valve 200, and a gas storage tank for monitoring the air pressure output of the height valve 200, wherein the gas supply tank is used to communicate with the air inlet of the height valve 200, and the gas storage tank is used to communicate with the air outlet of the height valve 200.

[0040] When the height valve 200 test device 100 provided by the present invention is used, the rotation of the first drive shaft 21 is converted into the movement of the first mounting block 13 along the length direction of the base 11 through the transmission member 22, so that the valve stem and the swing rod 220 can move relative to each other, that is, the swing rod 220 can reciprocate around the valve body 210, simulating the state of the height valve 200 when it is working normally, so as to test the durability of the height valve 200. The transmission structure of this scheme is simple, reliable, and space-saving. In addition, since the second mounting block 14 can move along the width direction of the base 11, the stroke of the swing rod 220 rotating around the valve body 210 is expanded, the inspection range is expanded, and the inspection result is more reliable.

[0041] It should be noted that, in this embodiment, the thickness direction of the base 11 is shown as F1, the length direction is shown as F2, and the width direction is shown as F3. In addition, when inspected at room temperature, the pressure of the gas source provided by the gas tank is generally controlled at about 11 bar; the gas storage tank is provided with a pressure sensor, which is a prior art and will not be described here. Specifically, in this solution, the first mounting block 13 is used to fix the valve body 210, and the second mounting block 14 is used to fix the swing rod 220.

[0042] For further information, see Figure 5 and Figure 6 The first transmission member 22 includes a transmission bar 221 fixed to the first driving shaft 21 and extending radially along the first driving shaft 21, and a first rotating shaft 222 is provided at one end of the transmission bar 221 in the extension direction; the first mounting block 13 is sleeved on the outer periphery of the first mounting rod 121, and a first guide groove 13a is provided on the side close to the first driving shaft 21 along the extension direction of the transmission bar 221, and the first rotating shaft 222 is slidably arranged in the first guide groove 13a, so as to drive the first mounting block 13 to move along the length direction of the base 11 when the first driving shaft 21 rotates.

[0043] In this solution, the first rotating shaft 222 is arranged at one end of the transmission bar 221 in its own length direction, that is, the first rotating shaft 222 is eccentrically arranged relative to the first driving shaft 21, so that when the first driving shaft 21 rotates, it can drive the transmission bar 221 to rotate. Since the first rotating shaft 222 is arranged in the first guide groove 13a, the first rotating shaft 222 can drive the first mounting block 13 to move along the length direction of the base 11, that is, this solution only uses the transmission bar 221 and the rocker arm 220 to realize the reciprocating motion around the valve body 210.

[0044] Furthermore, the first mounting block 13 is provided with a first fixing hole 13b of various types on a side away from the first driving shaft 21, for fixing one of the valve body 210 and the swing rod 220 of a corresponding type; the second mounting block 14 is provided with a second fixing hole of various types, for fixing the other of the valve body 210 and the swing rod 220 of a corresponding type. In this embodiment, by providing a first fixing hole 13b of various types on the first mounting block 13, and correspondingly providing a second fixing hole of various types on the first mounting block 13, valves 200 of different sizes and specifications can be fixed.

[0045] It should be understood that in one embodiment, at least one of the first mounting rod 121 and the second mounting rod 122 can be movably arranged along the width direction of the base 11 so that the distance between the first mounting rod 121 and the second mounting rod 122 can be adjusted, further improving the versatility of the device.

[0046] Further, one of the first mounting rod 121 and the first mounting block 13 is provided with a slide rail, and the other is provided with a slide groove matched with the slide rail, wherein the slide rail and the slide groove are extended along the length direction of the base 11. This solution realizes the movement of the first mounting block 13 through the cooperation of the slide rail and the slide groove, and the structure is simple, reliable, and easy to implement. Specifically, in this embodiment, the first mounting block 13 is provided with a guide hole along the length direction of the base 11, the first mounting rod 121 is inserted into the avoidance hole, the inner wall of the avoidance hole is recessed with a slide groove, and the first mounting block 13 is provided with a slide rail corresponding to the slide groove.

[0047] For further information, see Figure 7 , a mounting seat 15 is sleeved on the second mounting rod 122, and two guide plates 151 are arranged opposite to each other on the side of the mounting seat 15 away from the base 11, and each guide plate 151 is extended along the width direction of the base 11; the second mounting block 14 is slidably clamped between the two guide plates 151. In this solution, a guide channel is formed between the two guide plates 151, and the second mounting block 14 is slidably arranged in the guide channel, so that when the first mounting block 13 moves along the length direction of the base 11, the swing rod 220 can still drive the second mounting block 14 to move along the width direction of the base 11 when the stroke is large, avoiding interference between the swing rod 220 and the valve body 210, expanding the inspection range, and making the inspection structure more reliable.

[0048] Furthermore, in one embodiment, the second mounting block 14 is detachably disposed in the mounting seat 15 so as to be replaced with different second mounting blocks 14 having different fixing holes, thereby improving versatility.

[0049] For further information, see Figure 5 and Figure 6, the mounting seat 15 is movably arranged on the second mounting rod 122 along the length direction of the base 11. Specifically, the height valve 200 test device 100 also includes a second drive shaft 3 arranged corresponding to the mounting seat 15, the second drive shaft 3 is rotatably arranged on the mounting side 111 around an axis located in the thickness direction of the base 11, and a second rotating shaft 31 is eccentrically arranged at one end away from the mounting side 111; a second guide groove 15a is arranged on one side of the mounting seat 15 close to the second drive shaft 3 along the width direction of the base 11, and the second rotating shaft 31 is slidably arranged in the second guide groove 15a, so as to drive the mounting seat 15 to move along the length direction of the base 11 when the second drive shaft 3 rotates.

[0050] In this solution, the mounting seat 15 moves along the length direction of the base 11, so that the second mounting block 14 can also move along the length direction of the base 11, so that the range of movement of the swing rod 220 is further expanded and the operation is more flexible. In addition, since the second rotating shaft 31 is directly eccentrically arranged on the second driving shaft 3, when the second driving shaft 3 rotates, the second rotating shaft 31 drives the mounting seat 15 to move with improved accuracy, that is, the swing rod 220 can move more accurately relative to the valve body 210.

[0051] Specifically, the height valve 200 test device 100 further includes a first drive motor 23 and a second drive motor 4, wherein the first drive motor 23 and the second drive motor 4 are arranged on the side of the base 11 opposite to the installation side 111, wherein the first drive motor 23 is drivingly connected to the first drive shaft 21, and the second drive motor 4 is drivingly connected to the second drive shaft 3. In this solution, two motors are used to drive the first drive shaft 21 and the second drive shaft 3 to move separately, so that the device can improve its ability to cope with faults, that is, improve its risk resistance.

[0052] Further, in one embodiment, see Figure 8 and Fig. 9 , the height valve 200 test device 100 also includes a cabinet 5, and the side of the base 11 opposite to the installation side 111 is fixed to the inner wall of the cabinet 5. Specifically, in the present embodiment, the height valve 200 test device 100 also includes a temperature control system, and the temperature control system is used to control the temperature inside the cabinet 5. This scheme adjusts the ambient temperature inside the cabinet 5 through the temperature control system, so that the height valve 200 is tested at a predetermined temperature, simulating an extreme environment and increasing the reliability of the test indicators. It should be noted that the specific structure of the temperature control system belongs to the prior art and will not be elaborated here.

[0053] In addition, in another embodiment, at least one side wall of the cabinet 5 is provided with a plurality of heat dissipation holes to prevent the internal temperature of the cabinet 5 from being too high and ensure the normal operation of the device.
