[0027] DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0028] In order to make the purpose , technical scheme and advantages of this application more clearly, the application is further explained in detail by combining the attached drawings and embodiments . It is understood that the speci fic embodiments described herein are intended only to explain this Application and are not intended to quali fy it . In order to solve the technical problem of how to avoid the frequent wrong start of the hydraulic pump 110 , this application provides a liquid seal pump line structure . The first hydraulic gauge 320 in the liquid seal pump line structure can accurately measure the internal pressure of the connected pipe 220 , so that the hydraulic pump 110 can accurately start the liquid supply . Avoid the hydraulic pump 110 frequent wrong start and reduce the service li fe of the hydraulic pump 110 technical problems .

[0029] It should be noted that the liquid seal pump line structure of this application is used for but not limited to the autoclave , etc . For the convenience of explanation, in this application, only the liquid seal pump line structure is applied to the autoclave as an example to illustrate , and the principle of the liquid seal pump line structure applied to other types of equipment is essentially the same as the principle applied to the autoclave , which is not described here .

[0030] This application provides a liquid-sealed pump line structure , which includes a liquid supply component 100 , a connecting component 200 and a monitoring component 300 , and a liquid supply component 100 includes a hydraulic pump 110 , a first one-way valve 120 and a liquid supply pipe 130 , a hydraulic pump 110 is connected to one end of a liquid supply pipe 130 , and a first one-way valve 120 is installed on a liquid supply pipe 130 . The connecting component 200 comprises a second check valve 210 and a connecting pipe 220 . One end of the connecting pipe 220 is connected with the end of the liquid supply pipe 130 away from the hydraulic pump 110 , and the other end is connected with the autoclave . The monitoring component 300 includes a controller (not shown in the figure ) and the first hydraulic gauge 320 , which is located between the second one-way valve 210 and the liquid supply pipe 130 . The first hydraulic gauge 320 is used to detect the hydraulic pressure in the connected pipe 220 . The controller (not shown in the figure ) is electrically connected with the hydraulic pump 110 and the first hydraulic gauge 320 , respectively . After the pressure in the connecting pipe 220 is lower than the threshold, the hydraulic pump 110 is controlled to supply liquid to the liquid supply pipe In this embodiment , the first hydraulic gauge 320 is used to detect the pressure in the connecting pipe 220 . When the pressure in the connecting pipe 220 is lower than the threshold, the controller (not shown in the figure ) controls the hydraulic pump 110 to supply liquid to the liquid supply pipe 130 , so as to increase the pressure in the connecting pipe 220 . So that the pressure in the connecting pipe 220 can meet the sealing requirements . Because the first hydraulic gauge 320 is located between the first one-way valve 120 and the second one-way valve 210 , the pressure relief problem caused by the decrease of the sealing of the hydraulic pump 110 will not af fect the test results of the first hydraulic gauge 320 , so as to avoid the technical problems of the hydraulic pump 110 frequent wrong start and reduce the service li fe of the hydraulic pump 110 .

[0031] It should be emphasi zed here that when the pressure in the connected pipe 220 is below the threshold, the controller (not shown in the figure ) controls the hydraulic pump 110 to supply liquid to the liquid supply pipe 130 . The controller (not shown in the figure ) only applies simple logic control and does not involve complex rule algorithm . In addition, the controller with simple logic control is also widely used in the liquid seal pump line structure in the existing technology (not shown in the figure ) . Therefore , the use of the controller (not shown in the figure ) in this application still conforms to the relevant provisions of the patent law concerning the obj ect of application protection .

[0032] See Figure 1 , the hydraulic pump 110 and the first one-way valve 120 in the same dashed frame , which indicates that the first one-way valve 120 is directly installed on the pump body of the hydraulic pump 110 , the first one-way valve 120 and the guide outlet of the hydraulic pump 110 docking, so that the hydraulic pump 110 and the first one-way valve 120 is a complete package , the first one-way valve 120 can also be understood as a component of the hydraulic pump 110 pump body .

[0033] In some embodiments , the liquid seal pump line structure has two sets of liquid supply components 100 , both of which are connected to the connecting pipe 220 .

[0034] In this embodiment , the simultaneous use of two sets of liquid supply components 100 is a redundant design . When one set of liquid supply components 100 fails to work normally, the other set of liquid supply components 100 can still meet the pressure supplement demand . In addition, it can also make the two sets of liquid supply components 100 work alternately, which can avoid the frequent start-up of a single liquid supply component 100 and shorten the service li fe .

[0035] In some embodiings , a first check valve 120 is installed at one end of the supply pipe 130 near the connecting pipe 220 .

[0036] In this embodiment , because the first one-way valve 120 is installed at one end of the l iquid supply pipe 130 near the connected pipe 220 , the liquid flow in the connected pipe 220 can be ef fectively avoided from flowing back to the liquid supply pipe 130 .

[0037] In some embodiments , the connected component 200 al so includes a three-way valve 230 connected to a connecting pipe 220 and two supply pipes 130 , respectively .

[0038] In this embodiment , the connecting pipe 220 and the two supply pipes 130 are connected through the three-way valve 230 , respectively, so that the connecting pipe 220 and the two supply pipes 130 are connected to each other .

[0039] In some embodiations , the connecting component 200 also includes a third check valve 240 , which is installed in the connecting pipe 220 , and the third one-way valve 240 is located between the second one-way valve 210 and the autoclave .

[0040] In this embodiment , because the third one-way valve 240 is located between the second one-way valve 210 and the autoclave , the backflow of the autoclave seal liquid to the connecting pipe 220 can be avoided under the j oint action of the second one-way valve 210 and the third one-way valve 240 .

[0041] In some embodimentsthe monitoring assembly 300 also includes a second hydraulic gauge 330 installed between a third check valve 240 and an autoclave , which is used to detect the pressure in a connecting pipe 220 .

[0042] In this embodiment , a second hydraulic gauge 330 is installed between a third check valve 240 and an autoclave and is used to detect the pressure in a connecting pipe 220 . The second hydraulic gauge 330 can calibrate the first hydraulic gauge 320 , and whether the first hydraulic gauge 320 is faulty can be j udged by the second hydraulic gauge 330 . I f there is a di f ference between the number of the first hydraulic gauge 320 and the second hydraulic gauge 330 in the process of the hydraulic pump 110 , it indicates that the first hydraulic gauge 320 has a fault .

[0043] In some embodimentsthe first hydraulic gauge 320 is an electronic hydraulic gauge .

[0044] In this embodiment , since the first hydraulic gauge 320 and the controller (not shown in the figure ) are electrically connected to each other, the electronic hydraulic gauge can feed back an electrical signal to the controller (not shown in the figure ) .

[0045] In some embodiments , the second hydraulic gauge 330 is a mechanical hydraulic gauge .

[0046] In this embodiment , the mechanical hydraulic meter is more reliable , so that the mechanical hydraulic meter with higher reliability can be used to calibrate the electronic hydraulic meter with lower reliability .

[0047] In some embodiments , the supply pipe 130 is a stainless steel supply pipe 130 .

[0048] In this embodiment , because the supply pipe 130 is stainless steel supply pipe 130 , the supply pipe 130 has better corrosion resistance .

[0049] In some embodiments , the connecting pipe 220 is a stainless steel connecting pipe 220 .

[0050] In this embodiment , because the connecting pipe 220 is stainless steel connecting pipe 220 , the liquid supply pipe 130 has better corrosion resistance .

[0051] In order to better understand this application, the technical scheme of this application is explained in detail in accordance with Figure 1 below :

[0052] Firstly, the first hydraulic gauge 320 is used to detect the pressure in the connected pipe 220 . When the pressure in the connected pipe 220 is lower than the threshold, the controller (not shown in the figure ) controls the hydraulic pump 110 to supply liquid to the liquid supply pipe 130 , so as to increase the pressure in the connected pipe 220 , so that the pressure in the connected pipe 220 can meet the sealing requirements . Using two sets of liquid supply components 100 at the same time is a redundant design . When one set of liquid supply components 100 fails to work normally, the other set of liquid supply components 100 can still meet the pressure supplement demand . In addition, it can also make the two sets of liquid supply components 100 work alternately, which can avoid the frequent start-up of a single liquid supply component 100 and shorten the service li fe . Since the first hydraulic gauge 320 is located between the first oneway valve 120 and the second one-way valve 210 , the pressure relief problem caused by the sealability decline of the hydraulic pump 110 will not af fect the test results of the first hydraulic gauge 320 , and the second hydraulic gauge 330 is installed between the third one-way valve 240 and the autoclave , which is used to test the pressure in the connected pipe 220 . The second hydraulic gauge 330 can calibrate the first hydraulic gauge 320 , and whether the first hydraulic gauge 320 is faulty can be j udged by the second hydraulic gauge 330 . The first hydraulic gauge 320 in the above liquid seal pump line structure can accurately measure the pressure in the connected pipe 220 , so as to accurately start the hydraulic pump 110 for liquid supply, and avoid the technical problems of frequent wrong start of the hydraulic pump 110 and reduce the service li fe of the hydraulic pump 110 .

[0053] The above speci fic mode of implementation of this application shall not limit the scope of protection of this application . Any other corresponding changes and deformations made according to the technical ideas of the application shall be included in the scope of protection of the claims of the Application .
