Abstract
The invention discloses a flow-limiting valve seat of a high-pressure pump. The flow-limiting valve seat comprises a valve seat body. Liquid inlet channels are formed in the two sides of the valve seat body. One end of each liquid inlet channel is obliquely arranged, a conical opening is formed in a liquid inlet of each liquid inlet channel, and the bottom of each conical opening communicates with the corresponding liquid inlet channel. The two sides of each liquid inlet channel are further provided with flow-limiting chambers. The end, connected with the corresponding liquid inlet channel, of each flow-limiting chamber is a water inlet. Each flow-limiting chamber is internally provided with a buoy block, wherein a lug is arranged at the upper end of the buoy block and correspondingly clamped onto the corresponding water inlet. A water drainage channel is formed in the center of the valve seat body. In this way, the stability of the valve seat of the high-pressure pump can be improved, flow-limiting treatment can be carried out in time when high-pressure water flow spills into the liquid inlet channels of the valve seat, and the situation that the liquid inlet channels are impacted and damaged by the water flow is avoided; and when rapid water flow enters the liquid inlet channels, the buoy blocks in the flow-limiting chambers float to eject the lugs into the liquid inlet channels so that the liquid inlet channels can become narrow and play a flow-limiting role.
Description
Technical field
The present invention relates to high-pressure pump field, particularly relate to a kind of high-pressure pump current limliting valve seat.
Background technology
Jetting machine, is to make high-pressure plunger pump produce water under high pressure by power set to rinse the machine of body surface.Dirt can be peeled off by it, washes away, and reaches the purpose on cleaning of objects surface.Because being to use water jets under high pressure cleaning dirt, so high-pressure wash is also one of cleaning mode of universally acknowledged most scientific, economy, environmental protection.And high-pressure pump is that jetting machine is as important device, the stability of high-pressure pump directly affects the quality of jetting machine, and high pressure pump valve is the significant components in high-pressure pump, but traditional high pressure pump valve can not current limliting process, make high pressure pump valve after high-pressure pump extrudes the current of more high pressure by impact failure, and then the use of high-pressure pump can be had influence on.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of high-pressure pump current limliting valve seat, it is possible to increase the stability of high-pressure pump valve seat, can carry out current limliting process in time when valve seat feed pathway pours into supertension current.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of high-pressure pump current limliting valve seat, including valve seat body, described valve seat body both sides are provided with feed pathway, described feed pathway one end is obliquely installed, a bell is offered on described feed pathway inlet, connect with described feed pathway bottom described bell, described feed pathway both sides are additionally provided with current limliting chamber, it is water inlet that described current limliting chamber is connected end with described feed pathway, a buoy block it is provided with in described current limliting chamber, described buoy block upper end is provided with a projection, described projection correspondence is stuck on water inlet, described valve seat body central authorities offer drainage channel.
In a preferred embodiment of the present invention, described valve seat body two ends end face being equipped with seal washer, described seal washer is arranged in embedding described valve seat body.
In a preferred embodiment of the present invention, described projection and described buoy block are integral type attachment structure, it is connected to bottom described projection on described buoy block, described projection top is stuck on water inlet, described projection top is a curved end, described current limliting chamber water inlet after described buoy block float drive described projection eject water inlet to described feed pathway current limliting.
In a preferred embodiment of the present invention, described bell is that a reverse taper is opened on described feed pathway port, is slope outside described bell, and described bell upper end open is more than described feed pathway opening.
The invention has the beneficial effects as follows: the present invention can improve the stability of high-pressure pump valve seat, current limliting process can be carried out in time when valve seat feed pathway pours into supertension current, avoid feed pathway by water-hammering damage, when turbulent water enters feed pathway, buoy block in current limliting chamber floats in projection top to feed pathway, feed pathway is narrowed and plays metering function, and then it is the most steady to allow high-pressure pump run.
