Description

Technical Field

[0001] The present invention relates to the technical field of valve body performance detection, and particularly relates to a performance testing device for a deluge valve assembly. Background Art

[0002] A deluge valve is a valve used in a fire protection system, mainly used in an automatic sprinkler fire extinguishing system. When a fire occurs, it can be quickly opened to allow water to spray out through the sprinkler heads to extinguish the fire. It mainly consists of a hydraulic alarm bell, a water supply butterfly valve, a diaphragm, etc.; the diaphragm is usually made of natural rubber, which includes a middle convex part and a part responsible for closely cooperating with the valve body around the central convex part to form a sealing ring-shaped part. Under normal circumstances, the diaphragm cavity is filled with water to form a sealing surface with the inside of the valve body. When the deluge valve system is activated, it will be broken or displaced by pressure, and the water in the diaphragm is released, thereby opening the valve flap assembly. Therefore, its performance directly affects the reliability and service life of the deluge valve. In order to ensure that the deluge valve can be quickly and reliably activated during a fire, the performance detection of the diaphragm is very important.

[0003] However, the following problems exist in the current diaphragm detection process: The existing diaphragm detection method usually tests the tensile strength and elongation at break of the diaphragm through a tensile testing machine to evaluate its mechanical strength. However, when the diaphragm is specifically used, it will continuously be subjected to the lateral extrusion of the water pressure on the water supply side, and each time the deluge valve is used, the diaphragm will be compressed and restored. The existing testing method cannot detect the service life of the diaphragm under lateral pressure and vertical pushing pressure and the elastic performance of the diaphragm.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 As shown, a device for testing the performance of a deluge valve assembly includes an equipment frame 10 ; a bottom plate 11 is fixedly mounted on the equipment frame 10 , and a detection mechanism 2 and a fixing mechanism 3 are arranged on the bottom plate 11 .

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the detection mechanism 2 includes a rotating drum 20, and the rotating drum 20 is rotatably installed in the middle part of the base plate 11, and a turntable 21 located above the base plate 11 is fixedly installed on the rotating drum 20.

A support 24 is arranged above the turntable 21, and the support 24 is an inverted structure. The lower ends of the two vertical sections of the support 24 are respectively fixedly connected to the two sliders 23, and a push-pull portion 25 for pushing and pulling detection of the diaphragm is arranged at the upper end of the support 24. A driving portion 26 for driving the turntable 21 to rotate and the support 24 to slide is arranged on the base plate 11.

[0036] like Figure 2 , Figure 4 and Figure 5As shown, the fixing mechanism 3 includes a fixing frame 30, and the fixing frame 30 is fixedly installed on the upper end of the bottom plate 11. The fixing frame 30 is an inverted shaped structure. A through hole 31 for placing a diaphragm is opened in the middle of the horizontal section of the fixing frame 30 at a position coaxial with the turntable 21, and a pressing portion 32 is provided on the fixing frame 30 for squeezing, fixing and sealing the diaphragm and for inflating the diaphragm.

[0037] During specific work, the diaphragm is manually placed on the horizontal section of the fixing frame 30, and the spherical part of the diaphragm is passed through the through hole 31, and then the pressing part 32 squeezes and fixes the diaphragm from top to bottom, and then the diaphragm is pushed up and down reciprocatingly by the push-pull part 25 to detect the elastic performance and durability of the diaphragm, and then the push-pull part 25 is adsorbed and connected with the diaphragm, and then the driving part 26 drives the diaphragm to be pulled sideways and shaken circumferentially through the push-pull part 25 to detect the durability of the connection between the raised part and the annular part of the diaphragm, and the diaphragm is pulled vertically downward by the push-pull part 25 to detect the maximum tensile strength of the diaphragm, so as to comprehensively detect the performance of the diaphragm to ensure its service life.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, the pressing part 32 includes a rotation cylinder 320, and the rotation cylinder 320 is fixedly installed on the lower end of the horizontal section of the fixed frame 30. The telescopic section of the rotation cylinder 320 movably passes through the horizontal section of the fixed frame 30 and is fixedly installed with a pressure plate 321. The pressure plate 321 is provided with a measuring component for performing post-inflation detection on the diaphragm after vertical reciprocating extrusion, side pulling and shaking, and vertical stretching test operations.

[0039] like Figure 5 and Figure 7 As shown, the measuring component includes a No. 2 air inlet pipe 322, and the No. 2 air inlet pipe 322 and the pressure gauge 323 are fixedly installed on the upper end of the pressure plate 321, and the No. 2 air inlet pipe 322 and the pressure gauge 323 are both located in the range above the through hole 31, and the lower end of the No. 2 air inlet pipe 322 and the lower end of the pressure gauge 323 both pass through the pressure plate 321.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, the push-pull portion 25 includes a support plate 250, the support plate 250 is fixedly installed on the upper end of the support 24, a slide 251 is slidably installed on the front end of the support plate 250, a curved shell 253 with a concave upper part and a convex lower part is fixedly installed on the upper end of the slide 251 through a pillar 252, an actuator 4 for driving the slide 251 to move up and down is arranged on the support plate 250, and an adsorption component 5 for fixing it to the diaphragm is arranged on the curved shell 253.

[0041] like Figure 2 , Figure 4 and Figure 5 As shown, the actuator 4 includes a No. 2 motor 40, and the No. 2 motor 40 is fixedly installed on the rear end of the support plate 250. After the output shaft of the No. 2 motor 40 rotates and passes through the support plate 250, a disk 41 located below the slide 251 is fixedly installed, and a connecting rod 42 is hinged between the eccentric position of the disk 41 and the slide 251.

[0042] During specific operation, the corner cylinder 320 first drives the pressure plate 321 to move downward and rotate toward the diaphragm from a position away from the through hole 31 in the initial state until the pressure plate 321 rotates to just above the diaphragm, and then the corner cylinder 320 pulls the pressure plate 321 vertically downward to squeeze and fix the diaphragm. At this time, the diaphragm is sealed and only the No. 2 air inlet pipe 322 and the pressure gauge 323 are connected to its inner cavity; then the No. 2 motor 40 drives the disc 41 to rotate, and the disc 41 pushes the slide 251 to move back and forth up and down through the connecting rod 42, and the slide 251 makes the curved shell 253 move back and forth up and down through the support 252 to squeeze the diaphragm back and forth, so as to observe whether the diaphragm can rebound and recover, so as to detect the elastic performance and durability of the diaphragm, and the gas in the diaphragm can enter and exit through the No. 2 air inlet pipe 322 during the squeezing of the diaphragm.

[0043] After the diaphragm is squeezed in the vertical direction, the external air pump is connected to the No. 2 air inlet pipe 322 through the external delivery pipe to inflate the diaphragm, and then the No. 2 motor 40 pushes the curved shell 253 to fit the diaphragm through the disc 41, the connecting rod 42, the slide seat 251 and the support 252, and the diaphragm is inflated to keep the curved shell 253 squeezing the diaphragm, and then the curved shell 253 and the diaphragm are adsorbed and connected through the adsorption part 5, and then the gas in the inflated diaphragm is released, and then the driving part 26 first pulls the diaphragm through the curved shell 253 side , so that the pillar 252, which is initially concentric with the through hole 31, moves to the eccentric position of the through hole 31, and the driving unit 26 then drives the diaphragm that is kept side-pulled to shake to detect the durability of the connection between the raised portion and the annular portion of the diaphragm. Finally, the driving unit 26 drives the curved shell 253 to move and reset. At this time, the pillar 252 is concentric with the through hole 31 again, and the curved shell 253 remains connected to the diaphragm. Then the actuator 4 pulls the curved shell 253 downward, and the curved shell 253 pulls the diaphragm downward to measure the maximum tensile strength of the diaphragm.

[0044] After each test, the external air pump is connected to the No. 2 air inlet pipe 322 through the external delivery pipe to fill the diaphragm with gas of a certain pressure, and then observe whether the value of the pressure gauge 323 changes. If the value decreases, the tested diaphragm is unqualified, otherwise, the diaphragm is qualified.

[0045] like Figure 4 , Figure 5 and Figure 8As shown, the adsorbent 5 includes a No. 1 air inlet pipe 50, and the lower surface of the curved shell 253 is installed with a No. 1 air inlet pipe 50 connected with its interior, and the concave portion of the curved shell 253 is evenly installed with a number of suction cups 51 connected with its interior.

[0046] like Figure 5 , Figure 6 and Fig. 9 As shown, the driving part 26 includes a No. 1 motor 260, and the No. 1 motor 260 is fixedly installed at the lower end of the base plate 11. The output shaft of the No. 1 motor 260 rotates and passes through the rotating drum 20 and is fixedly installed with a spur gear 261. The left end of the right vertical section of the support 24 is fixedly installed with a rack 262 meshing with the spur gear 261, and a locking member 6 for limiting the rotation of the turntable 21 is provided on the turntable 21.

[0047] like Figure 5 and Figure 6 As shown, the locking member 6 includes a limit column 60, and two limit columns 60 located on the rear side of the support 24 are symmetrically arranged at the upper end of the turntable 21, and a limit hole 61 corresponding to the limit column 60 is opened on the bottom plate 11. The lower end of the limit column 60 slides through the turntable 21 and is located in the corresponding limit hole 61. The upper end of the limit column 60 is fixedly installed with an axle seat, and a tension spring 62 is fixedly installed between the lower end of the axle seat and the turntable 21, and the tension spring 62 is sleeved on the corresponding limit column 60. A limit component for limiting the rotation direction of the turntable 21 is arranged on the bottom plate 11, and a pushing member 7 for pushing the limit column 60 out of the limit hole 61 is arranged on the support 24.

[0048] like Figure 5 , Figure 6 and Fig. 9 As shown, the pushing member 7 includes a roller shaft 70, which is rotatably installed between two shaft seats, and a pushing block 71 is fixedly installed at the rear end of the support 24. The pushing block 71 is a right-angled trapezoidal structure with a rear end surface area smaller than a front end surface area and an inclined surface facing upward.

[0049] like Figure 2 , Fig. 9 and Fig.10 As shown, the limiting assembly includes a ring plate 63 , and the upper end of the base plate 11 is fixedly mounted with a ring plate 63 which is concentric with the turntable 21 and located outside the turntable 21 , and a ratchet pawl mechanism 64 is provided between the ring plate 63 and the turntable 21 .

[0050] During specific operation, the actuator 4 drives the curved shell 253 to fit with the diaphragm, and then the external air pump is connected to the No. 1 air inlet pipe 50 through a pipeline to suck the internal gas of the curved shell 253, so that the diaphragm can be adsorbed through the suction cup 51 to connect the curved shell 253 with the diaphragm, and then the No. 1 motor 260 drives the spur gear 261 to rotate forward. At this time, the limit column 60 limits the rotation of the turntable 21 in the limit hole 61, so that the rotation of the spur gear 261 will drive the support 24 to move backward through the rack 262, and the movement of the support 24 will cause the inclined surface of the pushing block 71 to come into contact with the roller shaft 70 to push the roller shaft 70 to move upward, and the roller shaft 70 will The two limit columns 60 are driven upward by the shaft seat to disengage from the limit holes 61 while the tension spring 62 is stretched. At this time, the slider 23, which initially contacts the inner wall of the front side of the slide groove 22, will slide to contact the inner wall of the rear side of the slide groove 22, thereby limiting the further movement of the support 24. The support 24 pulls the diaphragm to the side through the curved shell 253, and then as the spur gear 261 continues to rotate forward, it will drive the support 24, the turntable 21 and the curved shell 253 to drive the diaphragm to maintain a side-pulled state and perform periodic unidirectional shaking, so as to perform pulling tests on multiple positions of the connection between the diaphragm protrusion and the annular portion to detect the durability of the connection between the diaphragm protrusion and the annular portion.

[0051] After the detection is completed, the No. 1 motor 260 drives the spur gear 261 to reverse. Since a ratchet pawl mechanism 64 is provided between the turntable 21 and the ring plate 63, the rotation direction of the turntable 21 is limited. Therefore, the reverse rotation of the spur gear 261 will drive the support 24 to move forward and reset through the rack 262, and the pushing block 71 will move away from the roller shaft 70 with the movement of the support 24. The limit column 60 moves downward under the action of the tension spring 62 and is inserted into the corresponding limit hole 61 to completely limit the rotation of the turntable 21. Then the slider 23 contacts the front inner wall of the slide groove 22 to complete the reset, and then a certain amount of gas is filled into the diaphragm again to make the inside of the diaphragm reach a specific air pressure value, and then observe whether the pressure gauge 323 changes to detect whether the diaphragm is qualified. In addition, the amount of gas filled into the diaphragm can be changed to change the air pressure inside the diaphragm, and the above-mentioned vertical pushing and forward and backward pulling operations are repeated, and the changes in the value of the pressure gauge 323 are observed to detect the effective pressure value range required for the diaphragm to work.
