Abstract
The utility model relates to a valve body of a pneumatic control valve. The valve body of the pneumatic control valve comprises a main valve body (1), wherein a valve core hole (2) is formed in the middle of the main valve body (1). The valve body of the pneumatic control valve is characterized in that a cylinder circular bead (3) is arranged on one end portion of the main valve body (1), and an O-shaped ring is arranged on the cylinder circular bead (3). The valve body of the pneumatic control valve is integrally formed in an injection molding mode. The sealing surface and the inner wall surface of the valve core hole (2) are smooth and flat. Compared with a prior valve body, the sealing effect of the valve body of the pneumatic control valve is obviously improved in practical usage.
Description
Technical field
The utility model relates to a kind of valve body of Pneumatic valve, is mainly used on the pressure rod flow direction of control gas.
Background technique
The Pneumatic valve valve body that in the past was applied on the pressure rod generally adopts aluminum material to make, its structure as shown in Figure 1, have a plurality of O shape rings at aluminium matter valve body, be used for placing the O shape circle of sealing usefulness, these O shape rings generally all are to form by the polishing mode, the wall of unavoidable O shape ring can produce burr in bruting process, this sealing impact for Pneumatic valve is very large, the O shape ring smooth degree that forms by polishing in addition is not high, and also there is a shortcoming in this sealing configuration, because O shape ring is a plurality of independent settings, just can load onto after when O shape circle is installed, need to stretching, greatly reduce like this working life of O shape circle.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of integrated Pneumatic valve valve body is provided, and its sealing surface is not only smooth smooth, and sealing effect is higher.
The purpose of this utility model is achieved in that a kind of valve body of Pneumatic valve, comprise the valve body body, middle part at described valve body body has spool bore, is provided with the cylinder circular bead surface in an end of described valve body body, is provided with O shape circle at described cylinder circular bead surface.
The valve body body adopts plastic cement material.
Compared with prior art, the beneficial effects of the utility model are:
The valve body of a kind of Pneumatic valve of the utility model is one-body molded by the injection moulding mode, and its sealing surface and spool bore internal face are not only smooth smooth, and the actual sealing effect valve body more in the past that uses is significantly improved.
Description of drawings
Fig. 1 is the structural representation of Pneumatic valve valve body in the past.
Fig. 2 is structural representation of the present utility model.
Wherein:
Spool bore 2
Cylinder circular bead surface 3
O shape ring 4.
Embodiment
Referring to Fig. 2, the utility model relates to a kind of valve body of Pneumatic valve, comprise valve body body 1, have spool bore 2 at the middle part of described valve body body 1, end at described valve body body 1 is provided with cylinder circular bead surface 3, is provided with O shape ring 4 in the other end, and described spool bore 2 and cylinder circular bead surface 3 form by the injection moulding mode, can O shape be set at cylinder circular bead surface 3 and O shape ring 4 and enclose to realize sealing, the material selection plastic cement material of described valve body body 1.
Claims (2)
1. the valve body of a Pneumatic valve, comprise valve body body (1), have spool bore (2) at the middle part of described valve body body (1), it is characterized in that being provided with cylinder circular bead surface (3) in an end of described valve body body (1), be provided with O shape circle at described cylinder circular bead surface (3).
2. the valve body of a kind of Pneumatic valve according to claim 1 is characterized in that described valve body body (1) adopts plastic cement material.
