Abstract
The utility model discloses a valve switch for an underwater cleaning device, which includes a valve body, a valve core, an operating handle and a connecting piece, wherein the valve core is arranged in a cavity at the water inlet end of the valve body; the end part of the operating handle is fixedly connected with the valve core; the valve body is connected with a water manifold through the connecting piece; external threads are arranged at the water outlet end of the valve body; the connecting piece consists of a connecting threaded sleeve, a gland and a nut; the upper end part of the connecting threaded sleeve is in threaded connection with the water manifold; the end part of the water manifold penetrates the connecting threaded sleeve and the gland and is fixed by the nut; the lower end part of the connecting threaded sleeve is in threaded connection with the water outlet end of the valve body; the gland is covered in the water outlet of the valve body; and seal rings are arranged between the gland and the valve body as well as between the gland and the water manifold respectively. As the valve body is in threaded connection with the water manifold through the connecting piece, the valve switch for the underwater cleaning device facilitates the installation, greatly improves the sealing performance, and avoids the outer leakage of high-pressure liquid.
Description
Technical field
The utility model relates to a kind of threshold switch, specifically is a kind of threshold switch of washing unit under water.
Background technique
The threshold switch of the washing unit under water that tradition is used when being connected with aqueduct, need connect for a long time, and the phenomenon that high pressure liquid leaks can occur unavoidably, thus not only be not easy to install, but also influenced normal operation.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of threshold switch of washing unit under water of easy for installation, good seal performance.
To achieve these goals, the technological scheme of the utility model employing is:
The threshold switch of washing unit under water; Include valve body, spool, operating grip and link, spool is located in the cavity of inlet end of valve body, and the end of operating grip is fixedly connected with spool; Valve body is connected with aqueduct through link, and the water outlet end of said valve body is provided with outside thread; Said link is to constitute by connecting swivel nut, gland and nut; The upper end portion of said connection swivel nut is threaded with aqueduct; The end of aqueduct is passed and is connected swivel nut and gland and fix with nut; The underpart of said connection swivel nut is threaded with the water outlet end of valve body, and gland is buckled in the water outlet of valve body.
Be respectively equipped with seal ring between said gland and the valve body and between gland and the aqueduct.
The beneficial effect of the utility model: because valve body adopts the form that is threaded through link with aqueduct, not only made things convenient for installation, and improved sealability greatly, can effectively prevent leaking of high pressure liquid.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, valve body; 2, spool; 3, operating grip; 4, aqueduct; 5, connect swivel nut; 6, gland; 7, nut; 8, seal ring.
Embodiment
As shown in Figure 1; The threshold switch of washing unit under water; Include valve body 1, spool 2, operating grip 3 and link, spool 2 is located in the cavity of inlet end of valve body 1, and the end of operating grip 3 is fixedly connected with spool 2; Valve body 1 is connected with aqueduct 4 through link, and the water outlet end of valve body 1 is provided with outside thread; Said link is to constitute by connecting swivel nut 5, gland 6 and nut 7; The upper end portion that connects swivel nut 5 is threaded with aqueduct 4; The end of aqueduct 4 is passed and is connected swivel nut 5 and gland 6 and fixing with nut 7; The underpart that connects swivel nut 5 is threaded with the water outlet end of valve body 1, and gland 6 is buckled in the water outlet of valve body 1.Be respectively equipped with seal ring 8 between gland 6 and the valve body 1 and between gland 6 and the aqueduct 4.
Working principle: during work, valve body 1 is through link and after aqueduct is connected, and rotating operation handle 3 makes and can carry out conducting and close valve body.
The above is the preferred implementation of the utility model, can not limit the interest field of the utility model certainly with this.Should be pointed out that for those skilled in the art, the technological scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection domain of the utility model.
