Abstract
The invention discloses a water-pressure regulating type high-pressure pump valve seat which comprises a valve seat body. Liquid inlet channels are formed in the two sides of the valve seat body obliquely. Water pressure regulating chambers are arranged on the two sides of each liquid inlet channel and are of a hollow cavity structure inside. One end of each water pressure regulating chamber communicates with the corresponding liquid inlet channel through a water inlet, and flow limiting plates are further arranged at the two ends of each water inlet. Water absorbing resin balls are arranged in the water pressure regulating chambers. A drainage channel is arranged in the center of the valve seat body. In this way, water flow entering the liquid inlet channels in the high-pressure pump valve seat can be automatically regulated, when the water flow is rapid, the water absorbing resin balls in the water pressure regulating chambers adsorb water and then expand to be ejected out of the corresponding water inlets, the liquid inlet channels are narrower, and therefore the function of limiting the speed of the water flow is achieved.
Description
Technical field
The present invention relates to high-pressure pump field, particularly relate to a kind of hydraulic pressure regulation type high-pressure pump valve seat.
Background technology
High-pressure plunger pump is applicable to oil, chemical industry, chemical fertilizer industry as the high pressure water cleaning scale removal of industry, oil-field flooding, boiler feedwater, the power sources of hydraulic machinery such as flow process pump, metallurgy, the high-pressure water descaling of steel rolling mill, building, shipbuilding, sugaring, papermaking, chemical industry, and food, pharmacy etc. need to produce the part of highly pressurised liquid, pumped (conveying) medium is the fluid without solid particle.And high pressure pump valve is the significant components of high-pressure pump, but the water entering feed pathway can not be regulated and controled by traditional high-pressure pump valve seat, can not current limliting when current are the most anxious so that feed pathway or even whole valve seat are impacted by rapid stream, reduce valve seat service life.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of hydraulic pressure regulation type high-pressure pump valve seat, the current of feed pathway in entrance high-pressure pump valve seat can be regulated and controled voluntarily, expanding after water-absorbing resin ball absorption water allows feed pathway narrow, and then plays the function of current speed limit.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of hydraulic pressure regulation type high-pressure pump valve seat, including valve seat body, described valve seat body both sides offer feed pathway, described feed pathway is oblique to be opened in described valve seat body, described feed pathway both sides all offer hydraulic pressure regulation and control chamber, described hydraulic pressure regulation and control chamber interior is cavity structure, described hydraulic pressure regulation and control chamber connects with described feed pathway by offering water inlet, water inlet two ends are additionally provided with current limiting plate, it is provided with water-absorbing resin ball in described hydraulic pressure regulation and control chamber, described valve seat body central authorities are provided with drainage channel.
In a preferred embodiment of the present invention, described valve seat body two ends are also respectively embedded into sealing ring.
In a preferred embodiment of the present invention, push up described hydraulic pressure regulation and control chamber after the water suction of described water-absorbing resin ball and be connected on the water inlet of end with described feed pathway current are carried out speed limit regulation and control.
In a preferred embodiment of the present invention, described drainage channel vertically runs through to be offered in described valve seat body.
The invention has the beneficial effects as follows: the current of feed pathway in entrance high-pressure pump valve seat can be regulated and controled by the present invention voluntarily, expand after water-absorbing resin ball absorption water in hydraulic pressure regulation and control chamber when current are the most rapid and eject water inlet, allow feed pathway narrow, and then play the function of current speed limit.
