Abstract
The present invention relates to a kind of novel back pressure type back leakage connections, including valve body, steel ball, compressed spring, it is characterized in that the compressed spring is to become helix angle conical spring, the asphalt channel of valve body is stepped ramp type variable diameter passage, the diameter of steel ball is between heavy caliber channel diameter and small-bore channel diameter, and it is placed in heavy caliber channel, annular slot is provided at the passway inner edge in heavy caliber channel, microcephaly one end of compressed spring is withstood on steel ball, the steel ball other side is forced to withstand on the stepped locations of variable diameter asphalt channel, major part one end of compressed spring is caught in annular slot.In this way, former return filter connector is improved to steel ball and cone section spring composition counterbalance valve, increase oil return line back pressure, blowback hydraulic fluid port is kept to have a constant pressure, eliminate because in oil pocket oil return it is too fast due to lead to the problem of abnormal sound, more convenient people use, while in turn simplifying structure, cost is controlled, installation is facilitated.
Description
(1) technical field
The present invention relates to pressure-control valve fields, and in particular to a kind of novel back pressure type back leakage connection.
(2) background technique
Currently, being mostly ordinary couplings with the connector on variable pump and oil return line, vehicle is during fast running
When quick-release pedal, variable pump generates abnormal sound because oil return speed is too fast.Therefore, for solution dependent variable blowback speed oil is too fast and produces
The problem of raw abnormal sound, improves product quality, and inventing a kind of novel back pressure type back leakage connection has been urgent need.
(3) summary of the invention
The object of the invention is that providing a kind of novel back pressure type back leakage connection, other solutions, the apparatus structure are compared
Simply, at low cost, it is more convenient to install, just for producing manufacture in enormous quantities.
Technical solution of the present invention: novel back pressure type back leakage connection, including valve body, steel ball, compressed spring, it is characterised in that
The compressed spring is to become helix angle conical spring, and the asphalt channel of valve body is stepped ramp type variable diameter passage, steel ball
Diameter is placed in heavy caliber channel between heavy caliber channel diameter and small-bore channel diameter, in heavy caliber channel
Annular slot is provided at the inner edge of passway, microcephaly one end of compressed spring is withstood on steel ball, and the steel ball other side is forced to withstand on change
Major part one end of the stepped locations of diameter asphalt channel, compressed spring is caught in annular slot.In this way, by former return filter connector
It is improved to steel ball and cone section spring composition counterbalance valve, increases oil return line back pressure, keeps blowback hydraulic fluid port to have a constant pressure, disappear
Abnormal sound is led to the problem of except dependent variable blowback oil is too fast, more convenient people use, while in turn simplifying structure, control into
This, facilitates installation, and compressed spring is designed to change helix angle conical spring, can be at the maximum diameter of this conical coil spring
Play the role of circlip for hole, circlip for hole can be saved, saved cost, and facilitate installation, just for large quantities of
Amount is manufactured.The device not only can solve the abnormal sound problem of variable pump, while also may be mounted at hydraulic pump outlet, play
The effect for preventing system pressure from increasing suddenly and damaging hydraulic pump and preventing system oil liquid from flowing backwards.
The passway of the invention for being further characterized in that the heavy caliber channel is provided with the cone for being easily installed compressed spring
Shape flaring.Since flare is arranged in the passway in heavy caliber channel, be convenient for when installing in this way steel ball and compressed spring into
Enter into heavy caliber channel.
The overall diameter of major part one end of the invention for being further characterized in that the change helix angle conical spring is equal to
Or the diameter slightly larger than annular slot.Becoming helix angle conical spring in this way can preferably match with annular slot.
Back pressure in the asphalt channel of the invention for being further characterized in that the valve body is 0.2MPa.
The initial compression force of the invention for being further characterized in that the compressed spring is 10N.
A kind of fast-assembling method of novel back pressure type back leakage connection, it is characterised in that institute in the good claim 1 to 5 of pre-production
Valve body, the steel ball, compressed spring stated, are then assembled according to following steps: valve body being first provided with heavy caliber asphalt channel
One end place upward；Then steel ball is put into heavy caliber asphalt channel；Then positioning and guiding set is navigated on valve body；It connects
Compressed spring microcephaly one end is put into from positioning and guiding set into heavy caliber asphalt channel；Finally gently one pressed using compression bar,
It can complete to assemble.
Novel back pressure type back leakage connection is mounted on fuel tank, back pressure is generated, controls variable pump oil return speed, is solved because returning
The variable pump abnormal sound problem that oil pocket oil return is too fast and generates, it is simple that the utility model back pressure type back leakage connection reaches structure, easy for installation,
Effect at low cost.
(4) Detailed description of the invention
Fig. 1 is the perspective structure schematic diagram of novel back pressure type back leakage connection.
Fig. 2 is the schematic diagram of the section structure of novel back pressure type back leakage connection.
(5) specific embodiment
Below with reference to attached drawing and specific implementation, invention is further described in detail: in following attached drawing, number phase
With, illustrate it is identical, wherein 1 be valve body, 2 be steel ball, 3 be compressed spring, 4 be annular slot, 5 be taper be flared.
As shown in Figure 1, including valve body 1, steel ball 2, compressed spring 3, the compressed spring 3 is to become helix angle truncated cone spiral shell
Revolve spring, the asphalt channel of valve body 1 is stepped ramp type variable diameter passage, and the diameter of steel ball 2 is between heavy caliber channel diameter and small-bore
It between channel diameter, and is placed in heavy caliber channel, annular slot 4 is provided at the passway inner edge in heavy caliber channel, press
Microcephaly one end of contracting spring is withstood on steel ball 2, and 2 other side of steel ball is forced to withstand on the stepped locations of variable diameter asphalt channel, compresses bullet
Major part one end of spring is caught in annular slot 4, and the passway in the heavy caliber channel, which is provided with, is easily installed compressed spring 3
