A four-way valve using the piston component is further disclosed. The four-way valve using the piston component comprises a valve body with a valve cavity and a guide frame which is arranged in the valve body and can move horizontally relative to the valve body, the guide frame is connected with the piston disk, and the outer circumference of the sealing ring is matched with the inner wall of the valve cavity in sealing mode. The piston component and the four-way valve using the piston component are simple in structure and reduce production cost, the sealing ring is not easy to deform under the supporting of the circular groove of the piston disk, excircle size of the piston component is easy to control, the sealing ring is matched with the inner wall of the valve cavity of the four-way valve tightly, and sealing performance is enhanced.
Description
Technical field
The utility model relates to valve member, particularly a kind of piston element and use the four-way valve of this piston element.
Background technique
Four-way valve is mainly used in the air-conditioning system, is used for switching the flow direction of refrigerant, thereby realizes air-conditioning system refrigeration and the switching that heats.As shown in Figure 1; The four-way valve of producing in the market generally adopts internal baffle 01, exterior siding 02, profile of tooth spring 03, piston cup 04,05 5 part assemblings of piston rivet riveted way to produce with piston element; Piston element is connected with screw with the interior leading truck of four-way valve; Internal baffle is pressed in piston cup and profile of tooth spring on the exterior siding through the piston rivet, and the profile of tooth spring radially struts piston cup piston cup is cooperated with four-way valve valve pocket inner wall sealing.The shortcoming that such structure exists is: 1, there is stress man-hour in the structure of profile of tooth spring and piston cup adding in the piston element, and release that can stress after long-time the placement produces distortion, makes the piston cup excircle dimension be difficult to control.Because the valve pocket of piston cup and four-way valve is sealed and matched, the piston cup excircle dimension low pressure commutation ability that can influence four-way valve bigger than normal, and the meeting less than normal of piston cup excircle dimension causes the four-way valve internal leakage; 2, component are too much, and production and assembly technology is loaded down with trivial details, has strengthened working strength of workers, increase cost of production virtually.
The model utility content
The utility model problem to be solved just provides a kind of piston element, and is simple in structure, easy to make, and the excircle dimension of piston element is controlled easily, and long-term use is not yielding yet.The low pressure commutation ability and the interior sealing of valve of four-way valve have been guaranteed.
In order to solve the problems of the technologies described above; The utility model adopts following technological scheme: a kind of piston element is characterized in that: comprise piston plate, the outer circumference face of said piston plate is provided with at least one annular groove; Be provided with seal ring in the annular groove, the external diameter of seal ring is greater than the external diameter of piston plate.
Further, said seal ring is the rectangular seal of band gap.
Further, said seal ring is solid O-ring seals.
Further, the card of said piston plate is provided with groove.Alleviate the weight of piston plate, save the Manufacturing material of piston plate, reduce production costs.
The utility model also provides a kind of four-way valve that uses above-mentioned piston element in addition; Comprise the valve body that is provided with valve pocket and be located in the valve body leading truck of valve body move left and right relatively; It is characterized in that: said leading truck is connected with piston plate, and the outer circumference face of seal ring cooperates with the inner wall sealing of valve pocket.
Further, said piston plate is connected on the leading truck through piston blot, and piston plate is provided with the through hole that installs piston blot, and leading truck is provided with the tapped hole that cooperates with piston blot.Production, easy for installation.
After adopting technique scheme; The utlity model has following advantage: simple in structure; Reduce production costs, seal ring is difficult for deforming under the support of piston plate annular groove, and the excircle dimension of piston element is controlled easily; It is tightr to make that seal ring cooperates with four-way valve valve pocket inwall, and sealing is strengthened.
