Abstract
The utility model relates to a valve, in particular to a single-seat regulating valve of a sleeve. The technical scheme is that the single-seat regulating valve of the sleeve comprises a valve body, a valve core and a valve rod. The valve rod drives the valve core to move vertically so as to open or close the valve, an upper sealing device and a lower sealing device which can be in sealing fit with a valve seat of the valve are arranged on the valve core, and the lower sealing device is in plane sealing mode. The single-seat regulating valve of the sleeve is characterized in that the upper sealing device comprises a sealing member with a U-shaped cross section and a compensating spring arranged in a U-shaped cavity of the sealing member, two side faces of the U-shaped cavity of the sealing member are the same as the sealing face of the sealing member in the direction, and the compensating spring abuts against the two side faces of the U-shaped cavity of the sealing member. By the adoption of the technical scheme, the single-seat regulating valve of the sleeve overcomes defects of the prior art, and is a novel regulating valve which has rational structure, flexible opening and closing, good sealing effect and long service life.
Description
Technical field
The utility model relates to a kind of valve, particularly fingerstall tube single-seat adjusting valve.
Background technique
At present, our valve industry has obtained development fast, but the existing modulating valve identical with the utility model effect is because there are following problems in unreasonable structure: 1, sealing effect is bad, and modulating valve is easy to leak; 2, working life not long, seal ring just is being worn after using after a while, valve just leaks; 3, unreasonable structure, assembling is inconvenient.
Summary of the invention
The utility model overcomes the prior art defective, provide a kind of rational in infrastructure, open and close flexibly, the novel modulating valve of good sealing effect, long service life.
In order to realize above purpose, the utility model is by the following technical solutions: a kind of sleeve single-seat adjusting valve, include valve body, spool and valve rod, described valve rod drives spool and moves up and down opening or closing of realization valve, described spool be provided with valve seat with valve body can constitute be sealed and matched on, lower sealing device, described lower sealing device is a plane sealing, it is characterized in that: described upper sealing device includes the Sealing and the compensating spring that is arranged in the Sealing U-shaped chamber that cross section is a U-shaped, the bi-side in described Sealing U-shaped chamber are identical with the direction of the sealing surface of Sealing, and described compensating spring compresses with the bi-side formation in the U-shaped chamber of Sealing and cooperates.
By adopting such scheme, make the abrasion that has reduced Sealing between spool and the valve seat, Sealing is opened U-shaped cavity configuration and built-in compensating spring in adopting.Make sealing mechanism reach real dynamic seal (packing) by system media pressure.Built-in compensating spring is the abrasion of compensation sealing part effectively, makes that Sealing has elasticity in the switching process, can reduce friction greatly, improves sensitivity, makes whole modulating valve have good cut-out performance and durability.
Further setting of the present utility model is: described Sealing is arranged on the spool by fixed block, and fixed block is arranged on the spool by screw; Described valve body is provided with valve gap, and valve gap is provided with stuffing box, is provided with Gland, seal ring and packing ring between stuffing box and the valve rod.
The scheme of the utility model by further being provided with makes this modulating valve sealing effect better, more reasonable structure, and assembling is also more convenient, and Sealing is installed in addition also can be very convenient.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of sleeve single-seat adjusting valve, include valve body 1, spool 2 and valve rod 3, described valve rod 3 drives spool 2 and moves up and down opening or closing of realization valve, described spool 2 be provided with valve seat 11 with valve body 1 can constitute be sealed and matched on, lower sealing device, described lower sealing device is a plane sealing, in the utility model embodiment, described upper sealing device includes the Sealing 5 and the compensating spring 4 that is arranged in the Sealing U-shaped chamber 51 that cross section is a U-shaped, the bi-side 52 in described Sealing U-shaped chamber 51 are identical with the direction of the sealing surface 53 of Sealing 5, here said direction is identical do not need in full accord, as long as the power of 4 pairs of sides of compensating spring is forwarded on the sealing surface 53,53 pairs of valve seats of sealing surface are adjacent to get final product, described compensating spring 4 compresses with bi-side 52 formations in the U-shaped chamber 51 of Sealing 5 and cooperates.Adopt such scheme, make the abrasion that has reduced Sealing 5 between spool 2 and the valve seat 11, open U-shaped cavity configuration and built-in compensating spring 4 in Sealing 5 adopts.Make sealing mechanism reach real dynamic seal (packing) by system media pressure.The effectively abrasion of compensation sealing part 5 of built-in compensating spring 4 makes that Sealing has elasticity in the switching process, can reduce friction greatly, improves sensitivity, makes whole modulating valve have good cut-out performance and durability.
In the utility model embodiment, described Sealing 5 is arranged on the spool 2 by fixed block 6, and fixed block 6 is arranged on the spool 2 by screw, Sealing is installed is so just easily installed; Described valve body 1 is provided with valve gap 7, and valve gap 7 is provided with stuffing box 8, is provided with Gland, seal ring and packing ring between stuffing box 8 and the valve rod 3.
Valve of the present utility model only illustrates some preferred embodiments in this manual, is not to its restriction.This professional and technical personnel can structurally make various variations or modification according to the present utility model design and spirit, so these must belong to protection domain of the present utility model.
