Abstract
The utility model discloses an adjustable U-shaped pipe pressure gauge which comprises a casing and joints; flexible plastic tubes and straight glass tubes connected at two ends of the flexible plastic tubes are arranged in the casing; the flexible plastic tubes and the straight glass tubes connected at two ends of the flexible plastic tubes form a U-shaped tube; supporting springs are arranged inside the flexible plastic tubes; and buffer tanks are arranged at two ends of the U-shaped tube. The joints are connected with the buffer tanks through latex tubes; and adjusting nuts are arranged on the joints. A ruler is arranged on the casing. The adjustable U-shaped pipe pressure gauge has the benefits that the adjustable U-shaped pipe pressure gauge has simple structure, is convenient to use, hard to damage during the use and convenient for zero adjustment, and eliminates the maintenance work requiring frequent addition of the operating fluid.
Description
Technical field
The utility model relates to a kind of adjustable U type pipe pressure meter.
Background technology
Present U type pipe liquid manometer generally be glass tube is curved the U type and be fixed on plank or other solid panel on, pressure measurement pipeline joint direct and glass tube links, because the glass tube tube wall is thin and material is crisp frangible, very easily clashing and breaking in the use, and can not bear higher static pressure, pulse and when causing under temporary transient no to scale of force value acute variation or the roughly pressure unknown situation that outrange is used when institute's fluid measured pressure simultaneously at fluid suddenly, working fluid in the pipe is known from experience ejection or is sucked away, need frequent safeguarding, the zero-bit of liquid level can only be by injecting or extracting liquid out and regulate in addition, use trouble, so range of application is subjected to great restriction.
Summary of the invention
At above-mentioned prior art, in order to overcome the shortcoming that existing U type pipe liquid manometer is fragile and the easy loss of hydraulic fluid, zero-bit adjusting bother, the utility model provides a kind of novel U type pipe pressure meter, this U type pipe pressure meter is in use not fragile, hydraulic fluid also can not spray or be sucked away and cause loss, zero-bit is regulated flexibly, need not safeguard in the use.
The utility model is achieved through the following technical solutions:
Adjustable U type pipe pressure meter comprises shell, joint, the straight glass tube that is provided with flexible plastic tube in the shell and is connected the flexible plastic tube two ends, and flexible plastic tube constitutes U type pipe with the straight glass tube that is connected its two ends, and wherein, flexible plastic tube inside is provided with support spring; U type pipe two ends are provided with baffle-box.
Described joint is connected with baffle-box by emulsion tube, and joint is provided with setting nut.
Described baffle-box is connected U type pipe two ends by emulsion tube.
Described shell is provided with scale.
Shell of the present utility model is made by metal or engineering plastics, and strength of materials height, shock-resistant is not fragile.Inner have the plastic tube of support spring to constitute U type pipe by two straight glass tubes and an inside, U type pipe is connected by emulsion tube with two baffle-boxs respectively, the volume of each baffle-box is reasonable in design, its volume is greater than the normal volume of the hydraulic fluid that injects, so in use, cause the temporary transient no to scale of force value acute variation if pulsation takes place suddenly institute's fluid measured pressure or when may outrange under not clear situation using, the baffle-box of both sides all provides a cushion space respectively, working fluid cognition in the U type pipe enters baffle-box and can not spray or be sucked away, when hydrodynamic pressure just often hydraulic fluid can be back in the U type pipe, therefore can not cause the loss of hydraulic fluid; On two joints screw thread is arranged, can regulate liquid level in the U type pipe by setting nut, thereby be easy to regulate zero-bit, therefore needn't check maintenances, interpolation hydraulic fluid constantly, easy to use.
The beneficial effects of the utility model are: simple in structure, easy to use, and not fragile in the use, regulate zero-bit conveniently, exempt the maintenance work of often adding hydraulic fluid.

Fig. 1 is a structural representation of the present utility model.
Wherein, 1, joint; 2, setting nut; 3, baffle-box; 4, straight glass tube; 5, flexible plastic tube; 6, support spring; 7, scale; 8, shell.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of adjustable U type pipe pressure meter comprises shell, joint, as shown in Figure 1, the straight glass tube that is provided with flexible plastic tube in the shell and is connected the flexible plastic tube two ends, flexible plastic tube constitutes U type pipe with the straight glass tube that is connected its two ends, and wherein, flexible plastic tube inside is provided with support spring; U type pipe two ends are provided with baffle-box.
Described joint is connected with baffle-box by emulsion tube, and joint is provided with setting nut.
Described baffle-box is connected U type pipe two ends by emulsion tube.
Described shell is provided with scale.
Shell of the present utility model is made by engineering plastics, and strength of materials height, shock-resistant is not fragile.Inner have the plastic tube of support spring to constitute U type pipe by two straight glass tubes and an inside, U type pipe is connected by emulsion tube with two baffle-boxs respectively, the volume of each baffle-box is reasonable in design, its volume is greater than the normal volume of the hydraulic fluid that injects, so in use, cause the temporary transient no to scale of force value acute variation if pulsation takes place suddenly institute's fluid measured pressure or when may outrange under not clear situation using, the baffle-box of both sides all provides a cushion space respectively, working fluid cognition in the U type pipe enters baffle-box and can not spray or be sucked away, when hydrodynamic pressure just often hydraulic fluid can be back in the U type pipe, therefore can not cause the loss of hydraulic fluid; On two joints screw thread is arranged, can regulate liquid level in the U type pipe by setting nut, thereby be easy to regulate zero-bit, therefore needn't check maintenances, interpolation hydraulic fluid constantly, easy to use.
