Problems solved by technology
At present, automatic air release valves and independent safety valve devices are usually used in the interstages of positive displacement pumps and diaphragm reciprocating pumps. The product structure is complicated, and the installation is inconvenient, which is also not conducive to future maintenance.

Embodiment Construction
[0023] like figure 1 As shown, an exhaust safety device, the device includes a valve seat 1, the valve seat 1 is connected with a cylindrical valve body 3, and the valve seat 1 is provided with a hollow inlet along the direction of flow guide of the valve seat 1 13. The valve body 3 is provided with an outlet 14, and the cylindrical inner cavity of the valve body 3 is provided with an air release mechanism that communicates or closes the passage between the inlet 13 and the outlet 14. The air release mechanism is arranged in the valve body 3 connected to the pressure regulator.
[0024] In actual use, the valve seat 1 is installed at the radial position of the pump body or the hydraulic chamber casing, and the hollow inlet 13 of the valve seat 1 along its flow guiding direction constitutes a gas flow accumulation chamber to facilitate the discharge of gas and accumulation, the cleared gas pushes the deflation mechanism to open under the action of pressure to exhaust outward;...

The invention belongs to the technical field of pumps, in particular to a safe venting device which is used for venting between a volume delivery pump and a diaphragm type reciprocating pump. The safe venting device comprises a valve seat which is connected with a barrel-shaped valve body; a hollow inlet is arranged at the upper end of the valve seat along the flow diversion direction of the valve seat; the valve body is provided with an outlet; a gas releasing mechanism is arranged in the barrel-shaped inner chamber of the valve body and is used for communicating or closing a channel between the inlet and the outlet; and the gas releasing mechanism is connected with a pressure adjusting mechanism arranged in the valve body. The safe venting device is arranged at the radial position of a pump body or a hydraulic chamber shell and can avoid the reduction of the stroke volume of liquid actually generated in the pump body, or noise or vibration of equipment operation in the pump chamber caused by contraction or expansion movement generated by gas at a high pressure outlet end or in a hydraulic pressure cavity passageway due to the compressibility of gas. The safe venting device has a simple and compact structure, is simple and convenient to dismantle and is easy to maintain and replace.
Description
technical field [0001] The invention belongs to the technical field of pumps, and in particular relates to an exhaust safety device for interstage exhaust and safety of displacement pumps and diaphragm reciprocating pumps. Background technique [0002] For the air release valve, there are often two types of manual air release valve and automatic air release valve in chemical pump equipment. The manual air release valve needs to be operated manually, and when the gas is congested, if the air is not exhausted in time, the equipment will be in an abnormal working state. , and need to be manually closed after deflation, the operation is more troublesome, so the manual deflation valve has gradually faded out of the market; the automatic deflation valve can automatically deflate at any time, so the exhaust is more timely. Safety valves are mainly used to protect the discharge and utilization of high-pressure fluid pressure energy on industrial devices, and can also be used for ex...
