Abstract
Disclosed is a pointer type pressure gauge of capillary. The utility model is provided with a pressure sensor of an elastic tube (1), which is made of an arc-shaped elastic tube. One end of the pressure sensor of the elastic tube (1) is closed and the other end is connected with a pipe for inputting the pressure. The arc-shaped elastic tube is fixed on a base (2). The base is provide with a rotation axle (3) and a pointer (4) that is fixed on the rotation axle (3) and a gear (11).The closed end of the pressure sensor is connected with a bracket, which is fixed on a pin. The other end of the bracket is provided with a gear (7) that rotates around the pin. The gear (7) meshes with the gear (11) that is fixed on the rotation axle. The utility model is of a mechanical structure and can output the pressure as far as 1-1.5 meters with a simple structure and a small size.
Description
Technical field
A kind of pressure gauge, the especially pointer pressure of kapillary conduction of relating to of the present utility model.
Background technology
Existing tensimeter is the pressure indicator in direct contact pressure source closely, and is difficult to realize the pressure transmission.Even make pointer structure, its volume is also bigger.
Summary of the invention
The purpose of this utility model is: propose a kind of simple in structurely, the pointer pressure that volume is little especially is applicable to the pressure gauge that telemetering type pressure shows, is specially adapted to gas heater, wall hanging stove and similar applications heating equipment.
Technical scheme of the present utility model is: kapillary pointer-type pressure gauge, be provided with circular-arc elastic tube and make the elastic tube pressure transducer, the sealing of one end, the other end is connected with the pipeline of input pressure, circular-arc elastic tube is fixed on the pedestal, pedestal is provided with turning axle and is fixed in the pointer and the gear of turning axle, the pressure transducer blind end connects a support, support is fixed in a bearing pin, the other end of support is the gear around the bearing pin rotation, this gear and the gearing mesh that is fixed in turning axle.
The elastic tube of arcuation is the pipe that one section arc constitutes, and can be circular 1/4 to 3/4 arc length or one section ellipse arc (elastic tube that also comprises other camber line); Especially caliber is flat curved pipe, be that its cross section is round rectangle or ellipse, caliber is from coarse to fine or descending, blind end stretches to the displacement of the direction of circular arc expansion when being under pressure, drive is fixed in the bearing pin support and is rotated around bearing pin, and indicate by the pointer rotation that meshed gears drives fixing turning axle, pointer comes indicating graduation by the indication panel at the back side.One end of caliber thin (little) is a blind end.Make a thin end that suitable elasticity coefficient or modulus are arranged like this, be convenient to respond to the pressure size in pipe, make the displacement of blind end be proportional to the size of the pressure in certain interval, be delivered to pointer and indicate.
Characteristics of the present utility model are: this is a kind of mechanical structure, and is simple in structure, the pointer pressure gauge that volume is little.And can adjust the elasticity coefficient of pressure transducer, thereby provide different pressure indicating ranges by the wall thickness of adjusting the circular-arc elastic tube of indication.Can adapt to bigger pressure indicating range.The utility model can teletransmission reach pressure output at 1-1.5 rice, even longer, and the utility model can be avoided the abominable condition of work at pressure source place etc.Be specially adapted to gas heater, wall hanging stove and similar applications heating equipment.
