Abstract
The utility model relates to a check valve of an excavator tensioning apparatus which comprises a valve rod, a valve head and a nut. The utility model is characterized in that: the valve rod is internally provided with a groove for placing a steel ball, and a spring; the valve head is screwed down by the nut; and an elastic cylindrical pin is used for locking between the valve rod and the valve head. Compared with the prior art, the check valve of an excavator tensioning apparatus has the following advantages: simple and reliable structure, maintenance misoperation overcoming, high oil discharging speed, etc.
Description
Technical field:
The utility model belongs to the excavator accessory, especially a kind of excavator tension device one-way valve.
Background technique:
At present, the structure of 90 ° of one-way valves of domestic and international general excavator tension device is double nuts structures.Its structure is comparatively complicated, and number of spare parts is many, and in use the maintenance man easily carries out misoperation, as twist wrong hexagon nut when draining the oil maintenance, can cause inner body to eject to cause and scrap.
Summary of the invention:
The purpose of this utility model be to provide a kind of simple and reliable for structure, overcome maintenance misoperation, the fireballing excavator tension device one-way valve of draining the oil.
Technical solution of the present utility model is such, a kind of excavator tension device one-way valve, comprise valve rod, valve head, nut, feature is to be provided with groove in the described valve rod to place steel ball, spring, valve head nut screwing clamping, blocks with elastic cylindrical pin between described valve rod and the valve head; Described valve stem end is equipped with grease nipple; Described valve head seal with O ring.
The utility model compared with prior art has simple and reliable for structurely, overcomes the maintenance misoperation, advantage such as the speed of draining the oil is fast.
Description of drawings:
Accompanying drawing is an overall structure sectional view of the present utility model.
In the accompanying drawing, valve rod (1), grease nipple (2), steel ball (3), spring (4), valve head (5), O shape circle (6), elastic cylindrical pin (7), nut (8).
Embodiment:
Most preferred embodiment of the present utility model is such, shown in accompanying drawing, a kind of excavator tension device one-way valve, comprise valve rod, valve head, nut, wherein, be provided with groove in the described valve rod 1 and place steel ball 3, spring 4, valve head 5 usefulness nuts 8 and tighten, block with elastic cylindrical pin 7 between described valve rod 1 and the valve head 5; Described valve rod 1 end is equipped with grease nipple 2; Described valve head 5 usefulness O shapes circle 6 sealings.
During use, need to regulate grease nipple 2 directions and turn on nut 8 and get final product, mix up fastening nut 8 after the direction, grease nipple 2 directions are fixed the while everywhere can be from motive sealing.Do not exist and regulate and seal the situation of using double nut.
