Description
Technical Field
The utility model relates to a rack formula protection device when relief pressure valve became invalid.
Background
The pressure reducing valves exist in every liquid conveying pipeline in life, such as residential water supply and industrial production, but the pressure reducing valves lack emergency protection measures, once the pressure reducing valves fail, phenomena of pipe damage, downstream flushing and the like can be caused, and certain loss is brought to users. In order to solve the hidden troubles of equipment damage, water flooding downstream and the like caused by the failure of old and old pressure reducing valves and provide very reliable safety guarantee for the majority of residential users and industrial production, the research and development of a failure protection device of the pressure reducing valve are inevitable.
Disclosure of Invention
The utility model aims to solve the technical problem that a rack formula protection device when the relief pressure valve that can close the pipeline at once after the relief pressure valve in the fluid pipeline became invalid is provided.
The utility model adopts the technical proposal that: the utility model provides a rack formula protection device when relief pressure valve is out of service, its includes the valve body, set up the pressure sensor who is used for detecting the valve body internal pressure on the valve body, through pressure sensor control driving motor and with the gate that driving motor transmission is connected, the gate is used for opening or closes the valve body.
The utility model discloses be provided with the gate chamber on the valve body, the gate sets up in the gate intracavity, and driving motor is located the gate chamber top outside, and the gate realizes rising or descends under driving motor's drive.
The utility model discloses be provided with the tongue on the valve body, tongue and gate chamber smooth transition.
The lower part of gate is convex, and upper portion is squarely, the shape and tongue and the gate chamber looks adaptation of gate.
The utility model discloses the top of gate is fixed with the rack be provided with drive gear on driving motor's the output shaft, the driving gear meshes with the rack mutually.
The utility model discloses an actively the effect does: the utility model discloses set up pressure sensor and through motor control's flashboard on the valve body, driving motor automatic control flashboard is closed the valve body when pressure sensor detects the pressure in the valve body and is higher than the default, reaches the purpose in protection low reaches.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic cross-sectional view of an embodiment of the present invention;
fig. 3 is a schematic view of a structure of the shutter according to an embodiment of the present invention.
Detailed Description
Example 1: as shown in the attached drawings 1-3, the utility model discloses a valve body 1, set up pressure sensor 2 and the gate 6 of being connected with the 4 transmissions of driving motor that are used for detecting the fluid pressure in the valve body 1 on the lateral wall of valve body 1, gate 6 is used for opening or closing valve body 1. The valve body 1 is of a tubular structure, flange plates are arranged at two ends of the valve body 1 so as to be conveniently installed on a pipeline, the pressure sensor 2 is connected with a controller, and the controller controls the driving motor to be opened and closed and simultaneously realizes the opening and closing of the gate 6. The pressure sensor can adopt a PLC controller or a singlechip.
The valve body 1 is provided with a gate cavity 3, the gate 6 is arranged in the gate cavity 3, the driving motor 4 is positioned on the outer side of the top of the gate cavity 3, and the gate 6 is driven by the driving motor 4 to ascend or descend. When the pressure sensor 2 senses that the pressure in the valve body 1 is higher than a preset value, a signal is transmitted to the controller, and then the controller enables the driving motor to work.
The valve body 1 is provided with a convex groove 11, the convex groove 11 and the gate cavity 3 are in smooth transition, the lower part of the gate 6 is arc-shaped, the upper part of the gate is square, and the shape of the gate 6 is matched with the convex groove 11 and the gate cavity 3. The sealing degree between the gate 6 and the valve body 1 is increased, and the fluid leakage condition when the gate 6 is closed is reduced.
A rack 5 is fixed on the top of the gate 6, a transmission gear 7 is arranged on an output shaft of the driving motor 4, and the transmission gear 7 is meshed with the rack 5. The driving motor 4 is fixed on the top of the gate cavity 3, and the rack 5 is driven to convey vertically by the rotation of the transmission gear 7, so that the gate 6 is driven to move vertically together, and the opening or closing of the station gate is realized.
The utility model discloses an increase pressure sensor 2 and detect the fluid pressure in the valve body 1 on valve body 1 to control through the controller, when pressure sensor 2 detected the fluid pressure in the valve body 1 and is greater than the default, control driving motor closed gate 6, realized the function of automatic cutout, solved old, old relief pressure valve inefficacy and washed hidden danger such as equipment, water logging low reaches, provide very reliable safety guarantee for vast resident user, industrial production.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
