Description
Technical Field
The utility model relates to the technical field of high-pressure cleaning machines, in particular to a low-pressure-maintaining overflow system.
Background
The overflow system is an important component of the high pressure washer. The applicant applied for a chinese patent of patent No. cn201811181877.X, which mainly includes a valve seat, a valve rod disposed in the valve seat, and a valve core sleeved on the valve rod, wherein the front end of the valve rod is matched with the passage opening of the valve seat, so that the front end of the valve rod is made into an inclined plane matched with the passage opening of the valve seat in the prior art, but the precision required for doing so is higher, thus resulting in higher defective rate and higher cost.
Disclosure of Invention
The technical scheme to be solved by the utility model is as follows: the low pressure maintaining overflow system is low in defective rate and low in cost.
The technical scheme adopted by the utility model is as follows: the low pressure maintaining overflow system comprises a valve seat, a valve rod arranged in the valve seat, a valve core sleeved on the valve rod and a spring for propping against the valve core, wherein a passage opening is formed in the valve seat, and the valve rod comprises a rod body and a sealing ball arranged at the front end of the rod body and used for opening and closing the passage opening.
Preferably, the valve core is sleeved on the rod body to form a containing groove, and the sealing ball is arranged in the containing groove.
Preferably, the sealing ball is a steel ball.
Preferably, the steel ball is in interference fit in the accommodating groove.
Preferably, the width of the passage opening is larger than the radius of the steel ball and smaller than the diameter of the steel ball.
Preferably, the depth of the accommodating groove is larger than the radius of the steel ball and smaller than two thirds of the diameter of the steel ball.
Compared with the prior art, the utility model has the following advantages: the sealing ball is used for opening and closing the passage opening on the valve seat, so that the reliability is higher, the valve seat can be purchased directly, the high precision is not needed, and the cost can be reduced.
A containing groove is formed by the valve core and the valve rod, and then the sealing ball is arranged in the containing groove, so that the installation is convenient.
The sealing ball adopts the steel ball, and the steel ball is a product which is more conventional in the prior art, so the sealing ball can be directly purchased, has lower cost, is not easy to squeeze and deform, and has higher reliability.
The steel ball is in interference fit in the accommodating groove, so that the installation is convenient, and the steel ball cannot be separated from the accommodating groove.
The steel ball and the passage opening adopt the dimensions, so that the steel ball can well seal the passage opening, and the reliability is higher.
The steel ball and the accommodating groove adopt the size, so that the steel ball can be well in interference fit in the accommodating groove, and a part of the steel ball can extend out of the accommodating groove to seal the passage opening.

Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
Embodiment one:
the utility model provides a low pressurize overflow system, includes disk seat 1, valve rod, case 2 and spring 3, wherein:
a valve seat 1 provided with a passage opening 4, and in this embodiment, the width of the passage opening 4 is larger than the radius of the steel ball and smaller than the diameter of the steel ball;
the valve rod comprises a rod body 5 and a sealing ball 6, wherein the sealing ball 6 adopts a steel ball, the steel ball is in interference fit in the accommodating groove 7, and the passage port 4 on the valve seat 1 can be opened and closed through the steel ball;
the valve core 2 is provided with a through hole for the rod body 5 to pass through, the valve core 2 can be sleeved at the front end of the rod body 5, a containing groove 7 is formed at the front part of the valve core 2 after the valve core 2 is mounted at the front end of the rod body 5 for containing the steel ball, the rear part of the steel ball is arranged in the containing groove 7 and extends out of the containing groove 7, the part is used for being matched with the channel port 4, and in the embodiment, the depth of the containing groove 7 is larger than the radius of the steel ball and smaller than two thirds of the diameter of the steel ball;
the spring 3 is against the valve core 2 and is used for providing pressure;
when in a normal state, the valve core 2 can bear the steel ball against the passage opening 4 under the action of the spring 3, and the passage opening 4 is sealed by the steel ball; when the pressure of the passage opening 4 is enough to jack the steel ball, the steel ball drives the valve core 2 to squeeze the spring 3, which is equivalent to opening the passage opening 4.
While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
