Description

Technical Field

[0001] The utility model relates to the field of configuration or installation of control or safety devices, in particular to a boiling boiler pressure control valve. Background Art

[0002] When the boiler is in use, the pressure inside the boiler will change with the change of volume or temperature. Therefore, during the long-term use of the boiler, the internal pressure will gradually increase. If the pressure is not released in time, it will cause damage to the internal structure of the boiler or even explosion. Therefore, a pressure control valve is needed to ensure that the pressure inside the boiler is within a safe range. Most of the existing boiling boiler pressure control valves are directly fixed on the boiler by bolts when in use, which makes it more troublesome to inspect and replace the pressure control valve, making it inconvenient to quickly disassemble the pressure control valve, and then it is inconvenient to quickly fix the pressure control valve on the boiler; therefore, it is necessary to provide a boiling boiler pressure control valve to solve the above problems. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a boiling boiler pressure control valve, including a fixed base, a valve body is installed on the top of the fixed base, four corners of the fixed base are vertically opened with through holes, and a fixing rod is movably arranged inside each through hole, a circular seat body is fixedly arranged at the bottom of each fixed rod, and the circular seat body is located at the bottom of the four corners of the fixed base, the bottom of each circular seat body is fixedly set on the boiler, and fixing components are arranged at the front and rear ends of the fixed base, and the fixed base can be detachably installed on the boiler through the fixing components.

[0005] Furthermore, the fixing assembly includes a groove transversely opened on the end surface of the fixing base, a sliding rod is fixedly arranged between the two ends of the groove, and sliders are slidably arranged on the two end surfaces of the sliding rod, and the two sliders are slidably arranged at the two ends of the groove respectively.

[0006] Furthermore, a spring is fixedly connected between the two sliders, and the spring is sleeved on the surface of the slide rod. A handle is vertically fixed on the top of the two sliders, and the handle is located outside the groove.

[0007] Furthermore, a rectangular groove is transversely opened on the inner end surface of the groove in the fixed base, and the rectangular groove is transversely penetrated into the through hole, and a clamping rod is transversely slidably arranged inside the rectangular groove, and the inner end of the clamping rod is fixedly arranged on the inner end surface of the slider.

[0008] Furthermore, a clamping hole is formed transversely through the center of the fixing rod, and the clamping hole is correspondingly connected to the rectangular groove, and the outer end of the clamping rod is clamped into the clamping hole.

[0009] The beneficial effects of the utility model are as follows: the utility model is provided with a matching arrangement between structures such as a fixing rod, a sliding rod, a block, a spring, a handle, a clamping rod and a clamping hole. When the pressure control valve needs to be inspected and replaced, the two handles are pulled to drive the two sliders to move closer to each other. The movement of the two sliders closer to each other facilitates the compression of the springs. The movement of the two sliders closer to each other drives the two clamping rods to move closer to each other, so that the outer ends of the two clamping rods leave the two clamping holes, and then the fixing rod moves in the through hole, so that the pressure control valve can be quickly disassembled; the two handles are released, and the two sliders move away from each other under the action of the spring rebound force. The movement of the two sliders away from each other drives the two clamping rods to move away from each other, so that the outer ends of the two clamping rods are clamped into the two clamping holes, and then the fixing rod is fixed in the through hole, so that the pressure control valve can be quickly fixed on the boiler.
