Abstract
The utility mode discloses a vacuum angle valve which comprises a sealing seat, a sealing ring and a dovetail groove. The vacuum angle valve is characterized in that the sealing seat is a splitting type sealing seat which is formed by a sealing seat A and a sealing seat B; the sealing seat A and the sealing seat B are provided with half cone grooves which are corresponding with each other; and the half cone grooves are combined into the dovetail groove after the sealing seat A and the sealing seat B are formed into the splitting type sealing seat. According to the technical scheme, the vacuum angle valve has the advantages of being convenient to perform installation on the sealing ring, causing no damage to the sealing ring in the installation process and being convenient to perform replacement on the sealing ring due to the facts that the sealing seat is designed into a splitting type and the dovetail groove is formed by combination of the half cone grooves of the splitting type sealing seat which is formed by combination.
Description
Technical field
The utility model relates to valve field, particularly a kind of vacuum corner valve.
Background technique
The vacuum corner valve basic structure of generally using at present as shown in Figure 1, it mainly comprises: the structures such as outlet, sealing seat, dovetail groove, valve pocket, spool, drive unit, seal ring, import.The vacuum corner valve of this kind structure, dovetail groove integral body is machined on sealing seat, due to the special construction of dovetail groove, makes seal ring be difficult for installing and changing, and easily damage seal ring in assembly process.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of seal ring easy for installation, and installation process can not cause to seal ring the vacuum corner valve of any damage.
For achieving the above object, the technological scheme that the utility model proposes is: a kind of vacuum corner valve comprises sealing seat, seal ring, dovetail groove; It is characterized in that: described sealing seat is split type sealing seat, described split type sealing seat is comprised of sealing seat A and sealing seat B, described sealing seat A, sealing seat B are provided with half-cone groove in correspondence with each other, after described sealing seat A and sealing seat B formed split type sealing seat, described half-cone groove was combined into dovetail groove.
Adopt technique scheme, vacuum corner valve described in the utility model, by sealing seat being designed to the split formula, and dovetail groove has the half-cone groove of the split type sealing seat that combines to combine, and the beneficial effect that has is:
1) seal ring is easy for installation, and installation process can not cause any damage to seal ring;
2) change seal ring conveniently.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Fig. 2-4, a kind of vacuum corner valve, formed by outlet 11, split type sealing seat, dovetail groove 13, valve pocket 14, spool 15, device for driving valve body 16, seal ring 17, import 18, split type sealing seat is comprised of sealing seat A12a and sealing seat B12b, described sealing seat A, described sealing seat A12a is provided with half-cone groove a121, sealing seat B12b and is provided with half-cone groove b122, after described sealing seat A and sealing seat B formed split type sealing seat, described half-cone groove a121, half-cone groove b122 were combined into dovetail groove 13.
During concrete the use, adopt the utility model design, the installation method of seal ring is: first seal ring is enclosed within on the half-cone groove a121 of sealing seat A12a, then with in sealing seat A12a threading sealing seat B12b, forms a complete oat tail groove structure; The advantage that whole vacuum corner valve has is: seal ring is easy for installation, and it is convenient that installation process can not cause any damage to change sealing to seal ring.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
