Summary of the invention

The object of the invention is to defect and deficiency for prior art, a kind of novel cage type single seat regulating valve simple in structure, reasonable in design, easy to use is provided.

For achieving the above object, the technical solution used in the present invention is:

The novel cage type single seat regulating valve of one of the present invention, comprise valve gap, valve body, valve rod and spool, valve gap is fixedly connected by bolt and valve body, valve rod stretches into body cavity after valve gap and spool is fixedly connected, it also comprises sleeve, valve bonnet seal pad and valve base sealing pad, and sleeve is closely nested in the inner chamber of valve body, and spool is closely nested in the inner chamber of sleeve and valve body, described valve rod is provided with the lower directional post matching mutually with barrel bore, lower directional post be arranged on spool directly over; On the sidewall of described sleeve, be evenly provided with multiple throttle orifices, valve bonnet seal pad is arranged between the bottom end of valve gap and the top end of sleeve, and valve base sealing pad is arranged between the internal chamber wall of valve body and the bottom end of sleeve.

Further, the quantity of described throttle orifice is four.

Further, described valve bonnet seal pad and valve base sealing pad are O-ring seal.

Further, the inner chamber of described sleeve is divided into inner chamber, middle inner chamber and lower inner cavity from top to bottom successively, and the madial wall of middle inner chamber is provided with angle, and the number of degrees of described angle are 60 degree; The bottom of lower directional post is provided with the sealing surface matching mutually with middle intracavity sidewall.

Adopt after said structure, beneficial effect of the present invention is: the novel cage type single seat regulating valve of one of the present invention, comprise valve gap, valve body, valve rod and spool, valve gap is fixedly connected by bolt and valve body, valve rod stretches into body cavity after valve gap and spool is fixedly connected, it also comprises sleeve, valve bonnet seal pad and valve base sealing pad, sleeve is closely nested in the inner chamber of valve body, spool is closely nested in the inner chamber of sleeve and valve body, described valve rod is provided with the lower directional post matching mutually with barrel bore, lower directional post be arranged on spool directly over; On the sidewall of described sleeve, be evenly provided with multiple throttle orifices, valve bonnet seal pad is arranged between the bottom end of valve gap and the top end of sleeve, and valve base sealing pad is arranged between the internal chamber wall of valve body and the bottom end of sleeve.

In the time that use is of the present invention, substitute upper and lower sleeve and valve seat by sleeve, greatly simplify the internal structure of modulating valve, also reduce the connection of inner piece, so not only reduced by two moulds, saved cost of production, and reduced by a sealing gasket, guarantee the sealability of valve body; By lower directional post is set, guarantee the coaxality of spool and sleeve, make sealing more reliable.The advantages such as the present invention has simple in structure, arranges rationally, and fabricating cost is low.

Embodiment

Below in conjunction with accompanying drawing, the present invention is further illustrated.

As shown in Figure 1-2, the novel cage type single seat regulating valve of one of the present invention, comprise valve gap 1, valve body 2, valve rod 3 and spool 4, valve gap 1 is fixedly connected by bolt and valve body 2, valve rod 3 stretches into valve body 2 inner chambers after valve gap 1 and spool 4 is fixedly connected, it also comprises sleeve 6, valve bonnet seal pad 7 and valve base sealing pad 8, sleeve 6 is closely nested in the inner chamber of valve body 2, spool 4 is closely nested in the inner chamber of sleeve 6 and valve body 2, described valve rod 3 is provided with the lower directional post 5 matching mutually with sleeve 6 inner chambers, lower directional post 5 be arranged on spool 4 directly over; On the sidewall of described sleeve 6, be evenly provided with multiple throttle orifice 6-1, valve bonnet seal pad 7 is arranged between the bottom end of valve gap 1 and the top end of sleeve 6, and valve base sealing pad 8 is arranged between the internal chamber wall of valve body 2 and the bottom end of sleeve 6.
