Description
Technical Field
The utility model relates to an one-way disk seat for diesel engine returns oil pipe.
Background
The one-way valve on the oil return pipe of the diesel engine is mainly used for keeping a high-pressure oil pump, a suction inlet can maintain certain oil pressure, the suction inlet of the oil injection pump is not vaporized and cavitated due to too low oil pressure, and the continuity of oil supply of the high-pressure oil pump is ensured due to cavitation prevention, so that the diesel engine works stably.
Disclosure of Invention
The utility model aims at providing an one-way disk seat can guarantee the continuity of high-pressure oil pump fuel feeding, makes diesel engine job stabilization.
According to the technical scheme of the utility model, the one-way valve seat comprises a valve seat body, wherein the valve seat body comprises a water inlet section, a bent pipe section and a straight pipe section which are communicated with each other; the end surface of the water inlet section is divided into three water inlets, and a plurality of first connecting holes are formed in the periphery of each water inlet; and a water outlet is formed at the end part of the straight pipe section and is provided with a connecting flange, and a second connecting hole is formed in the connecting flange.
Furthermore, the three water inlets are arranged in a shape like a Chinese character 'pin'.
Furthermore, the diameter of the elbow section is gradually increased from the straight section to the water inlet section.
Further, a sensor mounting hole is formed in the straight pipe section.
Furthermore, the plane of the water outlet is vertical to the plane of the water inlet.
Furthermore, the water outlet extends out of the connecting flange.
The beneficial effects of the utility model reside in that: simple structure is reliable, can detect this internal fluid condition of disk seat, stabilizes the oil pressure to guarantee the continuity of high-pressure oil pump fuel feeding, make diesel engine job stabilization.

Description of reference numerals: 1-water inlet section, 2-bend section, 3-straight section, 4-water inlet, 5-first connecting hole, 6-water outlet, 7-connecting flange, 8-second connecting hole and 9-sensor mounting hole.
Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in the figure: one-way valve seat, including the valve seat body, the valve seat body includes inside communicating section of intaking 1, bend section of pipe 2 and straight tube section 3. Wherein, the outer end face of the water inlet section 1 is rectangular, and a connecting port of the water inlet section 1 and the bent pipe section 2 is arranged on one side of the rectangle. The outer end face of the water inlet section 1 is divided into three water inlets 4, and when the water inlet device is used, the water inlets 4 are arranged according to one-way valves. The periphery of edge water inlet 4 is rectangular periphery and is opened has a plurality of first connecting holes 5, and first connecting hole 5 can be the screw hole for connect the inlet tube. A water outlet 6 is formed at the outer end part of the straight pipe section 3, a connecting flange 7 is arranged at the water outlet 6, a second connecting hole 8 is formed in the connecting flange 7, and the second connecting hole 8 can be a threaded hole and is used for connecting a water outlet pipe.
Specifically, three water inlets 4 are arranged in a delta shape, and two water inlets 4 arranged side by side are arranged on one side of a connecting port of the water inlet section 1 and the bent pipe section 2. The diameter of the elbow section 2 is gradually increased from the straight pipe section 3 to the water inlet section 1. The straight pipe section 3 is provided with a sensor mounting hole 9 for mounting a sensor, so that the fluid condition in the valve seat body can be conveniently detected. The plane of the water outlet 6 is vertical to the plane of the water inlet 4. The water outlet 6 extends out of the connecting flange 7, so that the sealing installation is convenient.
