In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a doubly-forced meter seat, includes cylinder body, piston seal assembly, superhigh pressure seal assembly and connects the pole, the inside of cylinder body is fixed with the piston, be fixed with piston seal assembly between piston and the cylinder body, the one end of cylinder body is fixed with connects the pole, connect and be provided with superhigh pressure seal assembly between pole and the cylinder body, the other end that connects the pole is fixed with attach fitting, attach fitting is connected with superhigh pressure equipment, the cylinder cap is installed to the other end of cylinder body, it is sealed to be provided with the cylinder body between cylinder cap and the cylinder body, and manometer or pressure transmitter install on the cylinder cap.
Preferably, the cylinder cover, the cylinder body, the connecting joint and the connecting rod are made of stainless steel, and the pressure-bearing part is made of high-strength stainless steel.
Preferably, the cylinder is machined into a small hole diameter capable of reducing high-pressure water pressure at the position of the extension rod for limiting sliding of the piston.
Preferably, the cylinder body is filled with hydraulic oil, the cylinder cover is in threaded connection with the cylinder body, and the cylinder body is arranged to be sealed.
Preferably, the piston seal and the ultrahigh pressure seal are specially designed seals.
Preferably, the specially designed seal can ensure that hydraulic oil filled in the cylinder body is not leaked, high pressure and low pressure are not leaked, and the service life is more than 2000 hours.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses utilize attach fitting and connect the pole to be connected the superhigh pressure side with being detected equipment, superhigh pressure fluid promotes the piston motion through connecting the pole, fill hydraulic oil in the cylinder body, because the lifting surface area of piston both sides is unequal, thereby realized converting the superhigh pressure into the low pressure, then adopt relatively low-priced, stable performance's low pressure detecting element obtains the superhigh pressure signal indirectly, whole doubly power gauge stand passes through the cylinder body and seals, piston seal assembly and superhigh pressure seal assembly seal, improve the leakproofness, it detects the low pressure to convert the superhigh pressure to the detection, the shortcoming of current superhigh pressure direct detection has been overcome, make and detect the precision higher, long service life, the component cost reduces by a wide margin.
