Abstract
The utility model discloses a pressure regulator. A fixing ring is arranged at an operation end of a casing of a piston, and a piston rod is axially arranged in a cavity in the axis of the casing. A displacement indication rod is arranged on the piston rod, and an indication end of the displacement indication rod extends out of the outer circumference of the casing. The piston rod is connected with one end of a rotating shaft and is connected with the rotating shaft in a trapezoidal thread mode, and the other end of the rotating shaft penetrates out of the fixing ring to be connected with a cross-shaped hand wheel. A first bearing and a second bearing are sleeved on a part of the rotating shaft in the casing. The fixing ring is connected with the first bearing through a bearing locking ring, and the second bearing is abutted against and fixed with a shoulder in an inner cavity of the casing. The pressure regulator has the advantages that when pressure is boosted, a user can rotate the cross-shaped hand wheel to drive the rotating shaft to rotate, the rotating shaft is matched with the piston rod in trapezoidal thread mode to transmit power and to drive the piston rod to move axially, thereby realizing boost-buck output.
Description
Technical field
The utility model belongs to the instrument and equipment technical field, relates to a kind of pressure governor.
Background technique
Existing pressure governor, owing to adopt traditional piston rod (leading screw) structure, the piston range ability is long, and the physical dimension of whole device is bigger, and the operating space has been subjected to very big restriction, has influenced the scope of its use.
Summary of the invention
The purpose of this utility model provides a kind of pressure governor, has solved prior art and has adopted traditional piston rod (leading screw) structure, and the piston range ability is long, and the physical dimension of whole device is bigger, and the operating space has been subjected to the problem of very big restriction.
The technological scheme that the utility model adopted is, operation one end that is included in the shell of piston is equipped with retaining ring, in enclosure axis heart cavity, piston rod is installed vertically, the displacement indicating arm is installed on the piston rod, the excircle of shell is stretched out in the indication end of displacement indicating arm, piston rod is connected with an end of running shaft, and piston rod adopts trapezoidal thread to be connected with running shaft, and the other end of running shaft passes retaining ring and is connected with the cross handwheel; The part of running shaft in shell is set with bearing one, bearing two, and retaining ring is connected with bearing one by the bearing locking ring, and bearing two is close to fixing with the convex shoulder of shell inner cavity.
The beneficial effects of the utility model are that by rotating the rotation of cross handwheel driven rotary axle, running shaft cooperates transferring power with piston rod by trapezoidal thread during pressurization, moves axially the output of realization buck thereby drive piston rod.
Description of drawings
Fig. 1 is the gabarit structural representation of the utility model device;
Fig. 2 is the A-A schematic cross-section among Fig. 1.
Among the figure, 1. cross handwheel, 2. displacement indicating arm, 3. running shaft, 4. retaining ring, 5. bearing one, and 6. bearing two, 7. bearing locking ring, 8. shell, 9. piston rod.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
With reference to Fig. 1, Fig. 2, the structure of the utility model device is, operation one end that is included in the shell 8 of piston is equipped with retaining ring 4, in shell 8 axle center cavitys, piston rod 9 is installed vertically, displacement indicating arm 2 is installed on the piston rod 9, and the excircle of shell 8 is stretched out in the indication end of displacement indicating arm 2, and piston rod 9 is connected with an end of running shaft 3, piston rod 9 adopts trapezoidal thread to be connected with running shaft 3, and the other end of running shaft 3 passes retaining ring 4 and is connected with cross handwheel 1; The part of running shaft 3 in shell 8 is set with bearing 1, bearing 26, and retaining ring 4 is connected with bearing 1 by bearing locking ring 7, and bearing 26 is close to fixing with the convex shoulder of shell 8 inner chambers.
Bearing 1, bearing 26 all adopt deep groove ball bearing to cooperate with running shaft 3, rotate very light and flexible of cross handwheel 1 during pressurization.
During the pressurization of the utility model device, rotating cross handwheel 1 driven rotary axle 3 rotates, running shaft 3 and piston rod 9 cooperate transferring power by trapezoidal thread, move axially and realize buck output thereby drive piston rod 9, and the position of running shaft 3 is constant in this process.When not working, piston rod 9 one ends are retracted in the running shaft 3, compare with traditional piston rod (leading screw), have saved the operating space greatly.
