The invention discloses a pump head structure of a plunger pump, which comprises a pump head, wherein a water inlet channel, a water outlet channel and three plunger working chambers are formed on the pump head; a temperature control valve mounting hole and a pressure regulation structure mounting hole are formed on the pump head; a temperature control valve and a pressure regulation structure are arranged on the temperature control valve mounting hole and the pressure regulation structure mounting hole respectively; each plunger working chamber, a water outlet one-way valve and a water inlet one-way valve are connected into a group through a central channel; the water outlet one-way valve is arranged above the plunger working chamber of a corresponding group; the water inlet one-way valve is positioned outside the water inlet channel and is positioned below the water outlet one-way valve of a corresponding group; one end of the water inlet channel is provided with a water inlet filter screen, and the other end of the water inlet channel is sealed with a drain plug; the three plunger working chambers are arranged in an erected triangle shape; and the water inlet channel has a V-shaped structure and is inserted into the space between the plunger working chamber on the upper side and the two plunger working chambers on the lower side. The pump head structure has a small volume, a compact structure and attractive appearance.
Description
technical field [0001] The invention belongs to the technical field of plunger pumps, and more specifically relates to a pump head structure of a plunger pump. Background technique [0002] At present, the three plunger working chambers in the pump head structure of plunger pumps on the market are generally arranged horizontally and linearly, and their water inlet channels are linear. The pump head structure of the plunger pump with the above-mentioned structure has the following problems: because the overall volume of the pump head structure of the plunger pump is relatively large, the structure is not compact enough, small enough, and the manufacturing materials are many and the cost is high, and it is not beautiful at the same time. Contents of the invention [0003] The object of the present invention is to provide a plunger pump pump head structure with small volume, compact structure and very beautiful appearance. [0004] The object of the present invention is achi...
