Description

Manual pressure regulating device of plunger pump

Technical Field

The utility model relates to a plunger pump, more precisely, is a manual regulator of plunger pump.

Background

The plunger pump is an important device of a hydraulic system, and the plunger pump mainly depends on the reciprocating motion of a plunger in a cylinder body to change the volume of a sealed working cavity so as to realize oil absorption and oil pressing. Because the pressure in the cavity of the plunger pump is large, the pressure needs to be reduced to a proper pressure value during oil injection maintenance, but the existing method can only be completely emptied, so that the pressure in the cavity is too small.

Disclosure of Invention

The utility model discloses solve the technical problem that prior art exists to a manual regulator of plunger pump is provided.

The above technical problem of the present invention can be solved by the following technical solutions:

the manual pressure regulating device of the plunger pump is characterized in that the manual pressure regulating device of the plunger pump comprises a pump shell, the side wall of the pump shell is provided with a pressure regulating pipe orifice, the pressure regulating pipe orifice is provided with a detachable regulating part, the regulating part comprises an outer pipe and an inner pipe, the outer pipe is detachably connected with the inner pipe, the top center of the outer pipe is provided with an outer pipe hole, the bottom side wall of the outer pipe is provided with a pair of through expansion seams, the inner pipe comprises an inner screwed pipe and an inner clamping head, the bottom side wall of the inner pipe is provided with a pair of through pressure relief holes, a regulating handle respectively penetrates through the outer pipe and the inner pipe, the regulating handle comprises a vertically arranged handle rod, the top of the handle rod is provided with a transversely arranged handle head, and the tail end of the handle rod is provided with a conical regulating head, the adjusting head is matched with the pressure relief hole.

As the preferred embodiment of the utility model, the outer tube, the inner tube and the adjusting handle are made of brass.

The utility model discloses a manual pressure regulating device of plunger pump's advantage is: when the pressure regulating pipe is used, the inner pipe can be easily fixed into the pressure regulating pipe by a user by utilizing the inner screwed pipe, and the outer pipe is screwed on the inner screwed pipe. When needs pressure release, the user can directly hold the crown to promote adjustment handle, make the gap grow between conical regulation head and the pressure release hole, slowly release the high pressure in the plunger pump to a suitable pressure value, made things convenient for the oiling to maintain convenient operation greatly. The manual pressure regulating device of the plunger pump is simple in structure, obvious in effect, low in cost and high in practicability.
