Abstract
The utility model discloses a joint with a pressure protection device, which mainly comprises a joint part and an overvoltage protection device, wherein the overvoltage protection device comprises an aluminum foil and a protection seat, the aluminum foil is pressed in the protection seat, the protection seat is connected with the joint part through a thread, and an O-shaped sealing ring ensures the sealing of the joint; when the pressure of the working medium in the joint exceeds the rupture pressure of the aluminum foil, the aluminum foil is ruptured, the working medium overflows from the joint, and the pressure of the hydraulic system is reduced, so that other components in the system are protected. When the pressure protection device is used next time, the protection seat and the aluminum foil are detached, and the pressure protection device is installed again. The utility model discloses simple structure, part size are less, use and maintain simply, can guarantee that the hydraulic system oil circuit is in safe state.
Description
Technical Field
The utility model relates to a pressure protection device, concretely relates to take pressure protection device's joint.
Background
The hydraulic pipeline joint plays a role in connecting all components of the system in a hydraulic system, and the main parameters include pressure bearing capacity, pipe diameter and the like. The safety valve is generally designed in the hydraulic system, and when the pressure exceeds the opening pressure of the safety valve, the safety valve is opened to release the pressure, so that the purpose of protecting the hydraulic system by the pressure is achieved.
Pipeline joint and relief valve generally set up alone, and above-mentioned structure is complicated, and the cost is higher. At present, a device which is designed with a pressure relief device and a connector together and has the functions of pipeline connection and pressure relief in overpressure does not exist.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a take pressure protection device's joint.
Realize the utility model discloses the technical scheme of purpose does: a joint with a pressure protection device comprises a joint part, wherein the joint part is connected with a protection seat, and an aluminum foil is pressed in the protection seat.
Compared with the prior art, the utility model discloses a show the advantage and do: the utility model adopts the 'film' pressure relief principle, when the pressure exceeds the rupture pressure of the aluminum foil, the film is opened to relieve the pressure, thereby protecting the other components in the system; when the pressure protector is used next time, the protecting seat and the aluminum foil are detached, and the pressure protector is installed again; the utility model discloses simple structure, part size are less, use and maintain simply, can guarantee that the hydraulic system oil circuit is in safe state.
Drawings
Fig. 1 is a schematic view of a joint structure with a pressure protection device according to the present invention.
Detailed Description
As shown in figure 1, the joint with the pressure protection device comprises a joint part 1, wherein the joint part 1 is connected with a protection seat 2, and an aluminum foil 3 is pressed in the protection seat 2.
An O-shaped sealing ring 4 is arranged at the joint of the protective seat 2 and the joint part 1.
The protection seat 2 is connected to the joint portion 1 by a screw.
The protection seat 2 is provided with an opening in the middle, and the opening and the inside of the joint part 1 are separated by an aluminum foil 3.
The present invention will be described in detail with reference to the following examples.
Examples
A joint with a pressure protection device comprises a joint part 1 and the pressure protection device, wherein the pressure protection device is composed of an aluminum foil 3 and a protection seat 2, the aluminum foil 3 is pressed in the protection seat 2, the protection seat 2 is connected with the joint part 1 through threads, and an O-shaped sealing ring 4 ensures sealing of the joint. When the pressure of the working medium in the joint exceeds the rupture pressure of the aluminum foil, the aluminum foil is ruptured, the working medium overflows from the joint, and the pressure of the hydraulic system is reduced, so that other components in the system are protected. When the pressure protection device is used next time, the protection seat and the aluminum foil are detached, and the pressure protection device is installed again. The joint with the pressure protection device has the advantages of simple structure, small part size and simple use and maintenance, and can ensure that an oil circuit of a hydraulic system is in a safe state.
