The pressure reducing valve detecting device comprises a machine frame, a detecting sliding block and an alarm switch, wherein the detecting sliding block and the alarm switch are arranged on the machine frame, and the detecting sliding block is in sliding fit with the machine frame. The alarm switch is arranged above the detecting sliding block, the detecting sliding block is connected with an output shaft of an air cylinder and comprises a shell, a sliding rod and a piston, the sliding rod is arranged in an inner cavity of the shell, the piston is in close fit to the sliding rod in a sleeved mode, an upper air hole and a lower air hole are formed in the shell, the upper air hole is communicated to the upper portion of the cavity where the piston is located, and the lower air hole is communicated to the lower portion of the cavity where the piston is located. The upper end of the sliding rod can be in contact with the alarm switch, a sealing plug is in close fit with the lower end of the sliding rod, the lower end face of the shell is provided with a sealing ring, and a pressure reducing valve can be covered with the sealing ring. Air pipes are connected to the upper air hole and the lower air hole respectively. According to the technical scheme, the pressure reducing valve detecting device is simple in structure and high in detecting work efficiency.
Description
Technical field
The present invention relates to a kind of device of performing leak test of structure member, be specifically related to a kind of reduction valve pick-up unit.
Background technology
Reduction valve is a kind of special arrangement of automatic reduction working pressure of pipeline, and effect is after given pressure relief ranges, the medium of elevated pressures can be reduced to setting pressure.It can be reduced to the higher fluid pressure of pipeline before valve the required level of pipeline after valve.So the sealing of reduction valve is most important factor in its quality standard, it is also one of project that must detect.The artificial efficiency of using hand-operated tools to detect its sealing is lower.
Summary of the invention
The technical problem to be solved in the present invention is manually reduction valve to be detected to the inefficient shortcoming of impermeability in prior art.
In order to solve the problems of the technologies described above, the invention provides a kind of reduction valve pick-up unit, comprise frame, be arranged on detection slide block and alarm switch in frame, described detection slide block and frame are slidably matched; Alarm switch is arranged on and detects slide block top, detecting slide block is connected with the output shaft of cylinder, described detection slide block comprises housing, slide bar and piston, described housing and frame are slidably matched, described slide bar is arranged in housing inner chamber body, and piston closely cooperates and is enclosed within on slide bar, is provided with pore and lower pore on described housing, described upper pore leads to the top of piston place cavity, and described lower pore leads to the bottom of piston place cavity; Alarm switch can be touched in the upper end of described slide bar, and the lower end of slide bar is provided with close-fitting sealing-plug, and the lower surface of described housing is provided with the sealing ring that can cover reduction valve; Described upper pore and lower pore are connected with respectively tracheae.
Adopt the reduction valve pick-up unit tool of technique scheme to have the following advantages: reduction valve is sent to this pick-up unit below by rotary table, detect slide block down sliding, sealing ring covers reduction valve, and keep the impermeability of sealing ring and rotary table table top formation test chamber good, lower pore imports low-pressure air, slide bar is moved upward, make every effort to form vacuum in test chamber; If the sealing of reduction valve is qualified, the lower end of sealing-plug produces vacuum, and slide bar can upwards be done small movement, and slide bar can not touch alarm switch; If the sealing of reduction valve is defective, air will enter, and slide bar will continue to rise until touch alarm switch.Pressurized air is entered by upper valve, by test rod pushed home.
Further, sealing ring all has bolt to be fixedly connected with top cover.Simple in structure, working stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of reduction valve pick-up unit of the present invention.
Embodiment
Reference numeral in Figure of description comprises: frame 1, detects slide block 2, alarm switch 3, housing 4, slide bar 5, piston 6, upper pore 7, lower pore 8, sealing-plug 9, sealing ring 10.
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, a kind of reduction valve pick-up unit, comprises frame 1, is arranged in frame 1 and detects slide block 2 and alarm switch 3, and described detection slide block 2 is slidably matched with frame 1; Alarm switch 3 is arranged on and detects slide block 2 tops, detecting slide block 2 is connected with the output shaft of cylinder, described detection slide block 2 comprises housing 4, slide bar 5 and piston 6, described housing 4 is slidably matched with frame 1, described slide bar 5 is arranged in housing 4 inner chamber body, and piston 6 closely cooperates and is enclosed within on slide bar 5, is provided with pore 7 and lower pore 8 on described housing 4, described upper pore 7 leads to the top of piston 6 place cavitys, and described lower pore 8 leads to the bottom of piston 6 place cavitys; Alarm switch 3 can be touched in the upper end of described slide bar 5, and the lower end of slide bar 5 is provided with close-fitting sealing-plug 9, and the lower surface of described housing 4 is provided with the sealing ring 10 that can cover reduction valve; Described upper pore 7 and lower pore 8 are connected with respectively tracheae.Sealing ring 10 all has bolt to be fixedly connected with top cover.
Reduction valve is sent to this pick-up unit below by rotary table, detect slide block 2 down slidings, sealing ring 10 covers reduction valve, and keep sealing ring 10 and rotary table table top to form the impermeability of test chamber, lower pore 8 imports low-pressure air, slide bar 5 is moved upward, make every effort to form vacuum in test chamber; If the sealing of reduction valve is qualified, the lower end of sealing-plug 9 produces vacuum, and slide bar 5 can upwards be done small movement, and slide bar 5 can not touch alarm switch 3; If the sealing of reduction valve is defective, air will be by entering, and slide bar 5 will continue to rise until touch alarm switch 3.Pressurized air is entered by upper valve, by test rod pushed home.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
