The thixotropic mud injection device with the replaceable one-way valve comprises a one-way valve, a threaded short connector and a fixed flange which is fixed inside a shield body through hole; the two ends of the threaded short connector are respectively connected with the one-way valve and a manual ball valve; one end, connected with the one-way valve, of the threaded short connector is arranged in the shield body through hole; the threaded short connector is also connected with a connecting flange; the connecting flange is connected with the fixed flange through a bolt. According to the thixotropic mud injection device with the replaceable one-way valve, the one-way valve is arranged at one end of the threaded short connector, and the end, connected with the one-way valve, of the threaded short connector is arranged in the shield body through hole and is fixed by utilizing the connecting flange and the fixed flange, so that the normal operation of the thixotropic mud injection device is guaranteed, a mud leakage phenomenon is avoided, and the threaded short connector can be taken out conveniently for replacing the one-way valve; the thixotropic mud injection device with the replaceable one-way valve is easy to operate, convenient to use, simple in structure and easy to implement, the work efficiency is greatly improved, and the labor intensity of working personnel is reduced.
Description
Technical field
The utility model relates to a kind of thixotropic slurry injection device, relates in particular to the thixotropic slurry injection unit of the replaceable one-way valve of a kind of use on push pipe.
Background technology
Existing thixotropic slurry injection device, for inject thixotropic slurry (anti-friction agent) around shield body in the time of jacking construction, mainly adopts one way valve to prevent that mud from pouring in down a chimney, and avoids pipeline blockage.First existing thixotropic slurry injection device when mounted, need to be on shield body direct thread mill drilling, then one way valve is screwed into from shield body inner side, make one way valve outer end approach the external side of shield as far as possible.In actual mechanical process, for fear of spillage phenomenon occurs, very high to the technological requirement of thread mill drilling on shield body, to guarantee the threaded engagement precision of one way valve and screwed hole, add shield body steel plate thicker, thread mill drilling difficulty is large, cost is high, adds the inefficiency in man-hour.Secondly in the time that one way valve is installed, because push pipe is shorter by one way valve length, screwed hole space is little, one way valve is in place require a great deal of time with manually.Moreover in work progress; one way valve often can need to change because occur to stop up or damage phenomenon; because the one way valve in existing thixotropic slurry injection device is screwed in screwed hole deeply; when replacing, to one way valve be taken out very difficult; and be easy to the thread damage of shield body screwed hole, cause thixotropic slurry injection device normally to use.
Utility model content
The purpose of this utility model is to provide a kind of thixotropic slurry injection device of replaceable one-way valve, can guarantee that thixotropic slurry injection device normally works, avoid occurring spillage phenomenon, be convenient to staff changes one way valve simultaneously, have advantages of simple to operate, can increase work efficiency, reduce intensity of workers, reduce processing and manufacturing cost simultaneously.
The utility model adopts following technical proposals:
A kind of thixotropic slurry injection device of replaceable one-way valve, comprise one way valve, also comprise screw thread short circuit and the mounting flange that is fixed on shield body through hole inner side, the internal thread at screw thread short circuit two ends connects respectively one way valve and manual ball valve, one end that screw thread short circuit connects one way valve is arranged in shield body through hole, screw thread short circuit is also connected with adpting flange, and adpting flange and mounting flange are bolted.
Between described adpting flange and mounting flange, be provided with rubber washer.
Described screw thread short circuit and adpting flange welding.
Described adpting flange is connected by hexagon-headed bolt with mounting flange.
Between described hexagon-headed bolt and adpting flange, be provided with packing ring.
One way valve is arranged on screw thread short circuit one end by the utility model, and one end of screw thread short circuit connection one way valve is arranged in shield body through hole, utilize adpting flange and mounting flange to be fixed, both guaranteed that thixotropic slurry injection device normally works, avoid occurring spillage phenomenon, can take out easily again screw thread short circuit and change one way valve, simple to operate, easy to use, greatly improve operating efficiency, reduced intensity of workers, simple in structure, be easy to realize.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises screw thread short circuit 2 and is fixed on the mounting flange 4 of shield body through hole 3 inner sides, the two ends of screw thread short circuit 2 connect respectively one way valve 1 and manual ball valve 5, one end that screw thread short circuit 2 connects one way valve 1 is arranged in shield body through hole 3, screw thread short circuit 2 is also connected with adpting flange 6, and adpting flange 6 is connected with mounting flange 4 bolts.
In order further to guarantee result of use, adpting flange 6 is connected by hexagon-headed bolt 7 with mounting flange 4, between hexagon-headed bolt 7 and adpting flange 6, is provided with packing ring 8.Between adpting flange 6 and mounting flange 4, be provided with rubber washer 9.Screw thread short circuit 2 welds with adpting flange 6.
The utility model when mounted, shield body through hole 3 only need be set on shield body, again one way valve 1 and screw thread short circuit 2 are threaded connection, then the one end that screw thread short circuit 2 is connected to one way valve 1 is inserted in shield body through hole 3, finally will be bolted with screw thread short circuit 2 adpting flange 6 welding and the mounting flange 4 that is fixed on shield body through hole 3 inner sides.The utility model, without thread mill drilling on shield body, only needs the lower through hole of accurate to dimension requirement, has greatly reduced difficulty of processing and cost, has improved working (machining) efficiency.After install when one way valve 1, only needing one way valve 1 and screw thread short circuit 2 to be threaded connection in sufficient space, be directly inserted into through hole 3 in again, avoided plenty of time that existing thixotropic slurry injection unit spends in the time that one way valve 1 is installed and manually.In the time changing one way valve 1, user can unclamp the hexagon-headed bolt 7 that is connected and fixed flange 4 and adpting flange 6, and fech connection flange 6 and the welding body that screw thread short circuit 2 forms, can change the one way valve 1 that is arranged on screw thread short circuit 2 one end easily.
