The role of valve assembly

The valve assembly is the key component of the hydraulic end of the mud pump. The valve body assembly consists of: valve body, valve rubber, valve nut, guide

Frame, gland, circlip, steel ball, etc. (That is, the valve assembly has the valve seat removed). High working frequency, shock

Its quality directly affects the service life of the hydraulic cylinder, and it is the main component in the hydraulic end system of the drilling mud pump.

It is also one of the most used wearing parts in drilling work. Depending on the bore form of the valve seat, the valve assembly can be

It is divided into through-hole valve, three-rib valve and four-rib valve. The valve body and valve seat of the valve assembly are made of high-quality bonded steel 20CrMnTi

Carburizing and quenching, the surface hardness is greater than HRC60, and the cone surface is ground to ensure high roughness requirements and geometry

size. The four-rib valve body is made of high-quality forged steel, with high strength and hardness; the rubber is fixed on the valve body by the valve nut.

The valve seat has high strength and impact resistance, suitable for high pressure jet drilling. Compared with the four-rib valve body seat, the displacement of the three-rib valve body is larger,

At the same time, it can provide the valve body and valve rubber for direct assembly, and the service life is long. The rubber is made of polyurethane material, which is effective

The use time is more than 300 hours, which greatly improves the overall life of the valve assembly. The valve body produced by our company,

The material of the valve seat is 20CrMnTi, which is processed in strict accordance with the process requirements of the drawings, with high smoothness and high product quality.

Strength and high toughness. Our company can produce F series, 3NB series and other series of drilling pumps

Various specifications of valve body, valve seat. Supply tens of thousands of sets for domestic and foreign oil fields every year. Valve assembly consists of valve body assembly and valve seat

composition. The valve body and valve seat supplied by our company are formed by integral die forging of high-grade alloy steel, and are made in accordance with strict

The process stipulates the processing.
