Abstract

The utility model relates to the lubrication of a machine or a device, particularly a distributor with a distribution sliding valve conducting reciprocating movement. A new Grease distributor is composed of a valve body, a valve seat, an O-shaped ring, a pipe joint, a piston, a piston spring, a connector, a piston rod, an oil absorption spring and an indicating rod. The valve body is divided into two parts of a valve body for oil injection and a valve body for oil absorption threaded together or connected together by other methods. The utility model has the advantages of high sensitivity, no oil leakage, good reliability, long service life, etc.

Description

Novel drier oil distributor

The utility model relates to the lubricated of machine or equipment, especially has the dispensing device of to-and-fro motion distributing slide valve.

The existing dispensing device that has the to-and-fro motion distributing slide valve, the drier oil distributor of the Three way type valve body of present domestic use for example, ubiquity shortcomings such as operation acts is more dull, sensitivity is lower, leakage of oil is serious, reliability is relatively poor, working life is short.

The purpose of the utility model is to provide the novel drier oil distributor that a kind of working sensitivity is higher, reliability better, working life is long.

Novel drier oil distributor is by valve body and be contained in valve seat, zero shape circle and the pipe joint in valve body left side, be contained in the valve body right side piston body, be contained in piston spring and piston in the piston body, be contained in the outer coupling of piston body, be contained in the piston rod of valve body upside, oil suction spring and the indicating arm that is contained in the piston rod formed.Valve body is divided into oiling valve body and oil suction valve body two-part,, perhaps is linked together with additive method with scyewed joint together.

Below in conjunction with embodiment shown in the drawings, the utility model will be further described.

Accompanying drawing 1 is the utility model plan view, and accompanying drawing 2 is oil suction valve body plan views, and accompanying drawing 3 is oiling valve body plan views.

Shown in accompanying drawing 1 to 3, novel drier oil distributor is by valve body and be contained in valve seat 2, zero type circle 10 and the pipe joint 1 in valve body left side; Be contained in the piston body 14 on valve body right side, be contained in piston spring 13 and piston 11 in the piston body 14, be contained in the coupling 12 outside the piston body 14; Be contained in the piston rod 8 of valve body upside, the oil suction spring 7 and the indicating arm 6 that are contained in the piston rod 8 are formed.

Valve body is divided into oiling valve body 3 and oil suction valve body 5 two-part, with scyewed joint together, for preventing thread looseness, scribbles adhesive on the connection screw thread.Perhaps be linked together, for example welding, crimping or the like with additive method.Adjusting nut 4 and stop nut 9 also are equipped with in the outside of oil suction valve body 5.

Novel drier oil distributor is applied to grease lubricating system, and drier oil is distributed to each lubricating point.With pneumatic plunger dry oil pump and pneumatic and automatically controlled being used in combination, can realize multiple spot self oiling at regular time and quantity.Its working principle is summarized as follows: the drier oil by the pneumatic plunger dry oil pump is sent here, enter piston body 14 by coupling 12, and at this moment the pressure of drier oil can reach 10～17.5Mpa.Drier oil is pushed forward piston 11, is stored in drier oil in the distributor chamber and zero shape on the valve seat 2 circle 10 is pushed open and is entered pipe joint 1, by pipeline drier oil is transported to lubricating point then.When piston 11 reached the limit of the position, the drier oil of being brought by joiner 12 up pushed up piston rod 8, and indicating arm 6 exposes.And when in piston body 14 chambeies during release, piston spring 13 promotes pistons 11 and resets, oil suction spring 7 with piston rod 8 toward pressing down indicating arm 6 withdrawals.Simultaneously, the drier oil loop is stopped up in the also withdrawal of zero shape circle 10 on the valve seat 2, realizes an oiling.When dry oil pump moved once more, distributor repeated above-mentioned action again.

The valve body of existing drier oil distributor is that integral body processes.Because valve body is very asymmetric, thereby bores, expand, after the fraising, when the horizontal hole at fine finishing valve body center and upright opening, all lean on manual the grinding, often produce tapering, especially the bottom of upright opening usually grind less than, cause zero shape circle by sliding breaking and leakage of oil.The product that this hand lapping is come out is a main cause sensitive lower, that leakage of oil is serious, reliability is relatively poor, working life is short.And after the utility model is divided into two valve body, can on grinding machine, finish grind, guarantee the form and position tolerance and the machining accuracy of valve body inner bore, above-mentioned disadvantage has not completely had, thereby sensitivity is also high, and is oil-proof, reliability might as well, working life is also long.The update product of the drier oil distributor of the Three way type valve body that novel drier oil distributor is present domestic use.

In the embodiment shown in the figures, piston 11 is 5mm, and the boundary dimension of distributor is for long by 88.8, and is high by 36.This distributor can several be used in combination.
