Description
Technical Field
The utility model relates to the technical field of valves, specifically be a novel two H valves.
Background
The double H valves are arranged on the gear box and control the switching of high and low gears. The high-low gear switching is very frequent when the automobile runs, and the working condition environment of the position of the gearbox is severe. The traditional double H valve for the commercial vehicle gearbox generally comprises a valve body, an upper cover and a lower cover, wherein a valve rod is arranged in the valve body, a piston is pushed by a push rod to open or close a corresponding input port and an output port, and the gearbox is switched between a high gear and a low gear by controlling the switching of ventilation and air cut-off of the ports. The upper cover, the lower cover and the valve body are connected by bolts, so that the air tightness is poor, high-pressure gas in the valve body is easy to leak when the valve is used, and the phenomenon that high and low gears cannot be switched or the gear is difficult to engage is caused.
SUMMERY OF THE UTILITY MODEL
To the problem pointed out in the background art, the utility model provides a novel two H valves has the characteristics that the gas tightness is good.
The technical scheme of the utility model is realized like this:
the utility model provides a novel two H valves, includes valve body, upper cover, lower cover, be equipped with the valve rod in the valve body, be equipped with the ejector pin in the upper cover, be equipped with the spring in the lower cover, the valve rod is located the ejector pin with between the spring, its characterized in that: the upper cover with the lower cover all adopt the thread connection cover with the valve body is connected, the upper cover with the lower cover with the connection position of valve body is equipped with the sealing washer, the outside of sealing washer is equipped with the sealed piece that a plurality of intervals set up, and a plurality of sealed pieces are followed the circumference evenly distributed of sealing washer, every sealed piece all is equipped with the adjusting bolt who corresponds with it, the bolt runs through behind the thread connection cover with sealed piece butt cooperation.
The utility model discloses further set up to: the cross-sectional shapes of the sealing ring and the sealing block are both trapezoidal.
The utility model discloses further set up to: the upper cover with the lower cover with the interval of valve body sets up, the upper cover with the lower cover all is equipped with the butt arch, be equipped with the fixed slot on the valve body, the butt arch with the bottom butt cooperation of fixed slot.
The utility model discloses further set up to: and the abutting protrusions and the bottoms of the fixing grooves are provided with O-shaped rings.
To sum up, the beneficial effects of the utility model are that: the utility model provides a novel two H valves, the upper cover on it, adopt the threaded connection cover to connect between lower cover and the valve body, and the upper cover, be equipped with the sealing washer between lower cover and the valve body, the outside of sealing washer is equipped with the sealed piece that a plurality of intervals set up, sealed piece all is equipped with the adjusting bolt who corresponds with it, promote sealed piece extrusion sealing washer through adjusting bolt, increase the pressure of the contact surface between sealing washer and upper cover and the valve body and between sealing washer and lower cover and the valve body, prevent that gas from leaking from the contact surface department between sealing washer and upper cover and the valve body and between sealing washer and lower cover and the valve body.
