Problems solved by technology

However, on civil high-pressure pumps, especially cleaning high-pressure pumps with a pressure lower than 210BAR, safety protection valves have not been considered due to cost issues.
However, once these civil high-pressure pumps burst or explode, they are also very prone to safety accidents. Therefore, there is an urgent need for an accident-proof safety structure that does not increase costs and can also play a safety protection function.

Embodiment 1

[0013] Embodiment 1: see figure 1 As shown, an accident-proof safety structure includes a pump cover 1 and a plunger frame 2. A water outlet valve 3 is fixedly arranged on the pump cover 1. A safety hole 31 is arranged on the water outlet valve 3. A water outlet valve is arranged above the safety hole 31. 3. Sealed and fixedly connected safety element 32. The plunger frame 2 is provided with a plunger frame front cover plate 21, the plunger frame front cover plate 21 is covered on the water outlet valve 3, the plunger frame front cover plate 21 is provided with an overflow groove 22, the overflow groove 22 above the safety element 32 . When an unexpected situation occurs in the high-pressure plunger pump, the high-pressure water in the pump cover 1 will break through the safety member 32 , and the high-pressure water will flow out through the overflow groove 22 after breaking through the safety member 32 .

Embodiment 2

[0014] Example 2: see figure 2 As shown, the plunger frame 2 is provided with a plunger frame front cover plate 21 , and the water outlet valve 3 is provided with several support columns 33 , and the plunger frame front cover plate 21 covers the support columns 33 . When an accident occurs in the high-pressure plunger pump, the high-pressure water in the pump cover 1 will break through the safety member 32 through the safety hole 31 , and the high-pressure water will flow out through the gap between the support columns 33 after breaking through the safety member 32 . Other features are consistent with Example 1.

Embodiment 3

[0015] Embodiment 3: see image 3 As shown, the plunger frame 2 is provided with a plunger frame front cover plate 21, the plunger frame front cover plate 21 covers the water outlet valve 3, and the plunger frame front cover plate 21 is provided with a pressure transmission through hole 23 , the pressure transmission through hole 23 is disposed above the safety element 32 . The diameter of the end of the pressure transmitting through hole 23 close to the safety element 32 is larger than that of the safety element 32 . When an accident occurs in the high-pressure plunger pump, the high-pressure water in the pump cover 1 will break through the safety member 32 through the safety hole 31 , and the high-pressure water will flow out through the pressure transmission hole 23 after breaking through the safety member 32 . This is that other equipment can be connected in addition at the pressure transmission through hole 23, so that the high-pressure water can be gathered in one place...

Abstract

The invention discloses an accident prevention safety structure, and relates to an accident prevention safety structure for a high-pressure pump. A water outlet valve and a plunger frame are arranged on a pump cover. A plunger frame front shroud cover plate is arranged on the plunger frame, and covers the water outlet valve. A safety hole is formed in the water outlet valve. A safety part is arranged above the safety hole, and is fixedly connected with the water outlet valve in a sealed way; a gap is formed between the plunger frame front shroud cover plate and the safety part. Compared with the prior art, the accident prevention safety structure has the advantages that a pressure bearing part of the high-pressure pump can be prevented from being burst or exploded in case of an accident of the high-pressure pump, and pressure in the pump can also be rapidly released.

Description

technical field [0001] The invention relates to an anti-accident safety structure of a high-pressure pump, in particular to an anti-accident safety structure for a high-pressure plunger pump. Background technique [0002] Due to the high internal pressure of the high-pressure plunger pump during work, once an accident occurs, such as: the failure of the pressure regulating unloading valve, the failure of the one-way valve that acts as an unloading function, the blockage of the nozzle, etc., there will be pressure on the high-pressure pump. Possibility of parts bursting or exploding. Based on safety factors, safety protection devices must be configured on high-pressure pumps. In the field of high-pressure cleaning equipment, commercial high-pressure pumps with a general pressure greater than 350BAR are equipped with independent safety protection valves in structure. However, on civil high-pressure pumps, especially cleaning high-pressure pumps with a pressure lower than 210...
