Abstract
The invention relates to parts of mechanical equipment, in particular to a hydraulic valve body casing for a large excavator. According to the hydraulic valve body casing for the large excavator, a valve element through hole and a temperature-control medium flow channel are formed in a valve body, an impact rod connector is arranged at one end of the valve element through hole, and a push rod connector is arranged at the other end of the valve element through hole; five circular-ring-shaped flow channels are formed in the valve element through hole, the first circular-ring-shaped flow channel is communicated with the fifth circular-ring-shaped flow channel through a channel, the second circular-ring-shaped flow channel is communicated with the fourth circular-ring-shaped flow channel through a channel, oil grooves are formed in the channels respectively, and the third circular-ring-shaped flow channel located in the middle is connected with an oil outlet in the bottom of the valve body; three small circular-ring-shaped flow channels are further formed in the end, close to the push rod connector, of the valve element through hole; the temperature-control medium flow channel comprises medium channels which are located at the two sides of the valve element through hole, convex medium cavities are further formed in the medium channels, and each convex medium cavity is located between the two corresponding adjacent circular-ring-shaped flow channels. The valve body casting is used for multi-oil-path control and micro-movement control, the problem that only one oil path control mode can be achieved through an existing valve body is solved, a temperature-control medium enters the valve body so as to regulate and control the temperature of the hydraulic valve body, and normal work of a hydraulic valve is guaranteed.
Description
Technical field
The present invention relates to the parts of machinery, be specially large excavator hydraulic valve foundry goods.
Background technique
The large excavator of more than 20 tons, its hydrovalve structure and required precision higher, the particularly valve of some Multi-oil circuits, in working procedure, temperature rises very fast, and temperature is too high, cause the work that hydrovalve can not be stable, and wear extent is large.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of control accuracy high, carry out temperature control valve (TCV) body foundry goods, be mainly applicable to control complicated large excavator.
The present invention is achieved through the following technical solutions:
Large excavator hydraulic valve foundry goods, comprises valve body, has valve core through hole and temperature control medium runner in valve body, and valve core through hole one end is trip rod connection mouth, and trip rod connection mouth comprises preceding thread and sealed groove, and the valve core through hole the other end is push rod connection mouth; Valve core through hole there are five annulus runners, annulus runner communicates with valve core through hole, wherein first annulus runner and the 5th annulus runner pass through channel connection, second annulus runner and the 4th annulus runner pass through channel connection, each passage has oil groove respectively, and middle 3rd annulus runner is connected with the oil outlet of body base; Valve core through hole also has three small circle ring runners near push rod connection mouth one end; Described temperature control medium runner comprises the medium channel being positioned at valve core through hole both sides, the medium channel of both sides has medium inlet and media outlet respectively, the medium channel of both sides is connected by connecting passage, described medium channel also has evagination media cavity, and evagination media cavity is between adjacent rings runner.
Large excavator hydraulic valve foundry goods provided by the invention, can be used for multiple oil circuit control mode, and small circle ring runner is used for minor motion and controls, and solves the monotony that existing valve body oil circuit controls.Simultaneously temperature control medium enter in valve body, regulated and controled the temperature of hydraulic valve by temperature control medium, guarantee that hydrovalve normally works.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention;
Fig. 2 is temperature-controlled portion cross-sectional view of the present invention.
Embodiment
Accompanying drawings the specific embodiment of the present invention, as depicted in figs. 1 and 2, large excavator hydraulic valve foundry goods, comprise valve body 1, valve core through hole 2 and temperature control medium runner is had in valve body 1, valve core through hole 2 one end is trip rod connection mouth, and trip rod connection mouth comprises preceding thread 7 and sealed groove 8, and valve core through hole 2 the other end is push rod connection mouth 9; Valve core through hole 2 there are five annulus runners 3, annulus runner 3 communicates with valve core through hole 2, wherein first annulus runner and the 5th annulus runner pass through channel connection, second annulus runner and the 4th annulus runner pass through channel connection, each passage has oil groove 5 respectively, and middle 3rd annulus runner is connected with the oil outlet 6 bottom valve body 1; Valve core through hole 2 also has three small circle ring runners 4 near push rod connection mouth one end; Described temperature control medium runner comprises the medium channel 11 being positioned at valve core through hole 2 both sides, the medium channel 11 of both sides has medium inlet 10 and media outlet 12 respectively, the medium channel 11 of both sides is connected by connecting passage 13, described medium channel 11 also has evagination media cavity 14, and evagination media cavity 14 is between adjacent rings runner 3.
Be interconnected between annulus runner, can be used for multiple oil circuit control mode, with the addition of small circle ring runner 4, control for minor motion, solve the monotony that existing valve body oil circuit controls.Enter in valve body 1 simultaneously by temperature control medium, regulated and controled the temperature of hydraulic valve by temperature control medium, guarantee that hydrovalve normally works.Retain more temperature control medium between evagination media cavity 14 inherent adjacent rings runner 3, guarantee that temperature control medium can carry out temperature control in valve core through hole 2 fully.
