Abstract
The utility model discloses a pressure regulating valve which comprises a valve rod and a valve seat, wherein the valve rod penetrates into a central round hole of the valve seat and is connected with a steel ball in a matching way, the valve rod can reciprocate relative to the valve seat, the other side of the steel ball, opposite to the valve rod, supports against one end of a spring, the other end of the spring is fixedly connected with a steel ball seat, four axially extending ribs are uniformly arranged on the inner wall of the steel ball seat, the distance between every two opposite ribs is equal to the diameter of the steel ball, and the outer diameter of the spring is smaller than or equal to the diameter of the steel ball. The pressure regulating ball enables the steel ball and the spring to be positioned accurately when in reciprocation, and has a good sealing effect and high efficiency; and simultaneously, the service life of the pressure regulating valve is prolonged.
Description
Technical field
The utility model relates to a kind of steel ball type pressure regulator valve, relates in particular to the improvement of the steel ball seat structure of this pressure regulator valve.
Background technique
Along with the attention of people to environment and object housekeeping, the application of pressured fluid implement is more and more general.At present typical jetting machine mainly is made of spray gun and pressure water pump two-part, wherein pressure regulator valve is the key components of pressure water pump, it directly has influence on the working life of pump, is significant concerning pressure water pump so improve the performance of pressure regulator valve.Traditional pressure regulator valve sealing effect is not good, as accompanying drawing 1, seal by steel ball 3 and being connected of valve seat 4 in the pressure regulator valve, one end butt of steel ball 3 belows and spring 2, the other end of spring 2 is fixedly connected on the plug 1, and this structural design only can be located spring 2, and can not play positioning action for steel ball 3, the position is inaccurate when causing sealing after steel ball 3 to-and-fro motion again, the life-span of having reduced pressure regulator valve.
The model utility content
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of novel pressure regulator valve, sealability and the working life that can improve pressure regulator valve.
The purpose of this utility model will be achieved by the following technical programs:
A kind of pressure regulator valve, comprise valve rod and valve seat, described valve rod penetrates in the center hole of valve seat and connects with a steel ball, described valve rod valve seat relatively moves back and forth, described steel ball with respect to the opposite side of valve rod and an end butt of spring, the other end of described spring is fixedlyed connected with steel ball seat, be provided with 4 axially extended rib on the inwall of described steel ball seat equably, distance between 2 relative ribs equals the diameter of described steel ball, and the external diameter of described spring is less than or equal to the diameter of described steel ball.
Further, above-mentioned a kind of pressure regulator valve, wherein: described steel ball seat is provided with step, and described spring is fixedly connected on the step.
Outstanding effect of the present utility model is: the accurate positioning when to-and-fro motion of steel ball and spring, good sealing effect, efficient height, the life-span of improving pressure regulator valve.
Following constipation closes embodiment's accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.

Embodiment
A kind of pressure regulator valve of the present utility model, as Fig. 2～4, comprise valve rod 10 and valve seat 9, described valve rod 10 penetrates in the center hole of valve seat 9 and connects with steel ball 8, described valve rod 10 valve seat 9 relatively moves back and forth, described steel ball 8 with respect to the opposite side of valve rod and an end butt of spring 7, the other end of described spring 7 is fixedly connected in the step of steel ball seat 6, be provided with 4 axially extended ribs 11 on the inwall of described steel ball seat 6 equably, distance between 2 relative ribs equals or is slightly larger than the diameter of described steel ball 8, the external diameter of described spring 7 is less than or equal to the diameter of described steel ball 8, and described steel ball 8 and spring 7 can to-and-fro motion in the stop zone of rib 11.During the utility model work, valve rod 10 moves downward, penetrate in the valve seat 9, propping up steel ball 8 and spring 7 moves downward along the spacing cavity of rib 11 together, steel ball 8 relative valve seats 9 are subjected to displacement, original steel ball 8 and the sealing configuration that valve seat 9 forms are disappeared, and water inlet enters all the other hollow out positions in the steel ball seat 6 by valve seat 9; Opposite, valve rod 10 moves upward, because the restoring force of spring 7, steel ball 8 and spring 7 move up to along the spacing cavity of rib 11 together and prop up valve seat 9, return to the state of sealing again.Have good positioning when steel ball 8 of the present utility model moves up and down, the position that reseals after at every turn moving up and down is accurate, thereby has improved the life-span of pressure regulator valve.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technological schemes of forming all drop within the protection domain of the present utility model.
Claims (2)
1. pressure regulator valve, comprise valve rod and valve seat, described valve rod penetrates in the center hole of valve seat and connects with a steel ball, described valve rod valve seat relatively moves back and forth, it is characterized in that: described steel ball with respect to the opposite side of valve rod and an end butt of spring, the other end of described spring is fixedlyed connected with steel ball seat, be provided with 4 axially extended rib on the inwall of described steel ball seat equably, distance between 2 relative ribs equals the diameter of described steel ball, and the external diameter of described spring is less than or equal to the diameter of described steel ball.
