Abstract
The utility model relates to a screwing pressure limiting valve which consists of a, a cylinder screwing compressing spring 2 and a six-horn-head spring support 3, with the opening of the plunger valve sleeve 1 provided with a circular rim 11 which turns outwardly, the opening of the six-horn-head spring support 3 provided with a circular rim 31 which turns inwardly, and the plunger valve sleeve 1 moving freely and linearly in the six-horn-head spring support 3. Thanks to the integrated structure design, compared with the prior art, the utility model has the advantages of good condition in integration, simple and novel structure, convenient package and carrying, uneasiness in losing, etc. and does not lose any components during the arrangement and the starting, which is helpful for the measurement of the limiting valve starting pressure; the utility model is convenient to be installed and regulated during the pressure regulation and measurement and is easy to find whether the instability of the starting pressure of the pressure limiting valve is resulted from the valve or the limiting hole of the motor. The plunger valve sleeve 1of the utility model adopts the technique of moulding through the steel board cooling extrusion, which saves a large amount of steel, improves the working efficiency and reduces the production cost.
Description
Technical field
The utility model relates to a kind of a kind of pressure limiting parts that limit oil pump pressure, particularly a kind of whole sheath buckle type pressure-limit valve.
Background technique
In the main oil gallery system of existing TA1 type oil pump, be used to limit oil pump pressure pressure-limit valve structure as shown in Figure 1, it comprises 3 three of plunger valve pocket 1, cylindroid helicalcoil compression spring 2 and hexagon head latch brackets part independently separately, these three separately independently part can't be assembled into an integral body, after only attaching it in the pressure-limit valve bottom outlet, could form the parts of a cover pressure-limit valve function.Its deficiency is: part is lost easily, and this part transportation in bulk is inconvenient, is difficult to after the assembling adjust, and is very big to the stability influence of cracking pressure, is not suitable for and produces in enormous quantities and provision in set.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of good integrity, novelty simple in structure are provided, are convenient to the sheath buckle type pressure-limit valve packing, conveniently transport, be not easy to lose.
The technical solution of the utility model is: the sheath buckle type pressure-limit valve is made up of plunger valve pocket, cylindroid helicalcoil compression spring and three parts of hexagon head latch bracket; The oral area of plunger valve pocket has together to the round edge that turns up; The oral area of hexagon head latch bracket has the round edge that inwardly turns over together, and plunger valve puts the round edge that inwardly turns over and cooperates on the round edge that turns up and hexagon head latch bracket, make the plunger valve pocket can be in the hexagon head latch bracket line activities freely.
The further technological scheme of the utility model is: the oral area of plunger valve pocket is the right angle round edge to the round edge that turns up.
The utility model further technological scheme is: the round edge that the oral area of hexagon head latch bracket inwardly turns over is the right angle round edge.
The further again technological scheme of the utility model is: the plunger valve pocket adopts the steel plate cold-extrusion shaping.
The further again technological scheme of the utility model is: adopt cold-extrusion shaping when the round edge that the oral area of hexagon head latch bracket inwardly turns over assembles.
The utility model is owing to adopt the monolithic construction design, compared with prior art, advantage such as have good integrity, novelty simple in structure, be convenient to pack, conveniently transport, be not easy to lose, be installed to when starting, can not lack part, mensuration (the components type structural design in the past that helps pressure limiting valve opening pressure, after the part transposing of test back, the cracking pressure instability), be convenient to install, when pressure regulation is tested, be easy to regulate, when pressure limiting valve opening pressure is unstable, be easy to find reason (being the reason in valve or motor limit hole); The utility model plunger valve pocket adopts the steel plate cold extrusion technology, can save great deal of steel, improves work efficiency, reduces production costs.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Accompanying drawing 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, the sheath buckle type pressure-limit valve is made up of plunger valve pocket 1, cylindroid helicalcoil compression spring 2 and 3 three parts of hexagon head latch bracket; The oral area of plunger valve pocket 1 has one right angle to the round edge 11 that turns up, and it can disposablely shape, and also can adopt the steel plate cold-extrusion technology to shape; The round edge 31 that the oral area of hexagon head latch bracket 3 has one right angle inwardly to turn over adopts cold-extrusion shaping during these round edge 31 assemblings; The round edge 31 that the oral area of hexagon head latch bracket 3 inwardly turns over cooperates to the round edge 11 that turns up with the oral area of plunger valve pocket 1, make plunger valve pocket 1 can be in hexagon head latch bracket 3 line activities freely.
During assembling, the oral area of hexagon head latch bracket 3 leaves the surplus on inside squeeze buckle limit, and after plunger valve pocket 1 and spring 2 covers were buckled in the hexagon head latch bracket 3, the inside cold-extruded of the oral area of hexagon head latch bracket 3 was pressed into the round edge 31 that one right angle inwardly turns over and gets final product.
Claims (5)
1. sheath buckle type pressure-limit valve, it is made up of plunger valve pocket, cylindroid helicalcoil compression spring and three parts of hexagon head latch bracket; The oral area that it is characterized in that the plunger valve pocket has together to the round edge that turns up; The oral area of hexagon head latch bracket has the round edge that inwardly turns over together.
