Description
Technical Field
The utility model belongs to the technical field of measuring force, and particularly relates to a piston type putty isolator.
Background
In water conservancy grouting construction, accurate measurement of grouting pressure relates to grouting quality. When measuring grouting pressure, because grouting cement slurry can solidify, the manometer can not direct contact cement slurry, must connect on grouting pipeline through the putty isolator, and the effect of putty isolator is the transmission pressure, does not let cement slurry and pressure transmitter contact, prevents that cement slurry from getting into the manometer and solidifying and blocking up and leading to the damage. The traditional putty isolator adopts a rubber cup to isolate cement slurry, hydraulic oil is filled in the rubber cup to transfer pressure, in the use process, the rubber cup is easy to break, the cement slurry enters the pressure gauge to cause damage, the rubber cup needs to be checked once in two or three days, the rubber cup needs to be replaced frequently, the damage frequency is higher when the grouting pressure is higher, and the maintenance workload is higher. The bottom cavity of the putty isolator is large, cement slurry is easy to remain, the slurry is solidified, the bottom cavity is blocked, the bottom cavity is frequently cleaned, butter is also frequently filled in the bottom cavity in the field construction process to prevent the cement slurry from entering, but the effect is not obvious, the butter is easy to be washed away by the slurry, and finally the slurry is blocked.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, but the present utility model is not limited to the following embodiments.
In fig. 1, a piston type putty isolator of the present embodiment is formed by connecting a pressure interface member 1, a compression nut 2, a seal ring 3, an outer cylinder 4, a metal piston 5, and a retainer ring 6. The outer cylinder body 4 is cylindrical, the external diameter is 5cm, the length is 10cm, the check ring 6 is connected to one port of the outer cylinder body 4 through threads, the pressure interface piece 1 is fixedly installed on the other port through the compression nut 2, the thickness of the check ring 6 is 2.5-5 mm, the thickness of the check ring 6 in the embodiment is 3mm, the piston is prevented from falling out, meanwhile, the space at the bottom of the outer cylinder body 4 is reduced, the residue of grouting liquid is reduced, the cleaning is easy, the outer cylinder body 4 is prevented from being blocked, the compression nut 2 is in threaded connection with the other end of the outer cylinder body 4, the sealing ring 3 is installed between the pressure interface piece 1 and the other end port of the outer cylinder body 4, the hydraulic oil is prevented from leaking, the inner diameter of a pressure inlet a of the pressure interface piece 1 is smaller than the inner diameter of the outer cylinder body 4, the metal piston 5 is installed in the outer cylinder body 4, the outer diameter of the metal piston 5 is in the shape of a cylindrical barrel, the bottom of the metal piston 5 is located at one end of the check ring 6, and hydraulic oil is filled in the outer cylinder body 4 between the metal piston 5 and the pressure interface piece 1.
When the grouting device is used, one end of the outer cylinder body 4 provided with the retainer ring 6 is arranged on the grouting pipeline 8, the pressure gauge 7 is arranged on the pressure interface piece 1, as shown in fig. 2, the hydraulic pressure of cement slurry in the grouting pipeline 8 is increased, the piston is pushed to move towards the direction of the pressure interface piece 1, hydraulic oil is compressed, the hydraulic oil acts on the pressure gauge 7, and the pressure of the grouting pipeline 8 is detected by the pressure gauge 7. The thickness of the retainer ring 6 is 2.5-5 mm, so that the bottom of the metal piston 5 is almost flush with the port of the outer cylinder body 4, the bottom space of the putty isolator is reduced, the bottom space of the metal piston 5 can be completely washed by washing a pipeline after grouting is finished, cement slurry is not easy to remain, and the putty isolator is not easy to be blocked.
