Abstract
The utility model relates to an adjusting valve steel casting, in particular to a high and middle pressure main steam adjusting valve steel casting. The technical scheme is that: the high and middle pressure main steam adjusting valve steel casting comprises a valve body and a valve core; an executing piece is arranged at the upper end of the valve body; the executing piece controls the valve core to move through a valve rod so as to open and close the valve; the high and middle pressure main steam adjusting valve steel casting is characterized in that: the executing piece is arranged on the valve body through a bracket; a guide seat of the valve rod is arranged at a hinging position between the bracket and the valve body; an elastic sleeve is arranged between the guide seat and the valve core; and a sealing ring is arranged between the guide seat and the elastic sleeve. By adoption of the scheme, the high and middle pressure main steam adjusting valve steel casting which aims at the shortcoming in the prior art and has good sealing effect and long service life is provided.
Description
Technical field
The utility model relates to a kind of modulating valve Cast Steel, particularly a kind of high pressure main steam control valve Cast Steel.
Background technique
Be used for the used main steam control valve Cast Steel of pharmacy, biology, cosmetics and grocery trade production and mainly include valve body, spool and actuator, be provided with valve rod between actuator and the spool with the spool interlock; When valve rod is subjected to the actuator axial slip its axially operation need to keep stable, not then can cause seal spool incessantly to occur revealing, for this reason, the guide holder that plugs for valve rod is not installed on valve body usually, reach valve rod with this and move axially stable purpose.In order to guarantee the sealing between guide holder and the valve body, the hard sealing block of ring-type is set between valve body and guide holder usually, though hard sealing block can use the sealing that guarantees valve body and guide holder in the early stage, and valve rod is inserted on the guide holder to move and also can causes certain pressure to guide holder, can produce friction between guide holder and the hard sealing block, friction then can cause the wearing and tearing of hard Sealing and guide holder for a long time, and its sealing is inevitable also can be affected.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of good airproof performance, the novel high pressure main steam control valve Cast Steel of long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of high pressure main steam control valve Cast Steel, include valve body and spool, described valve body upper end is provided with actuator, actuator moves by valve rod control spool, thereby realize opening and closing of valve, it is characterized in that: described actuator is arranged on the valve body by support, the joining place of described support and valve body is provided with the guide holder of valve rod, be provided with elastic sleeve between guide holder and the spool, be provided with seal ring between described guide holder and the elastic sleeve.
By adopting such scheme, the problem that the utility model can well the customer service prior art exists provides a kind of good sealing effect, the stop valve of long service life, be provided with seal ring between guide holder and the elastic sleeve in addition, being provided with of seal ring can guarantee its sealing.
Further setting of the present utility model is: described guide holder lower end is stepped, and the end of elastic sleeve one end is fastened on the stepped portion of guide holder, and the stepped portion of guide holder offers short slot, and described seal ring places in this short slot; The side face that described guide holder is connected with valve body is provided with the shoulder rank, and the corresponding part on valve body and these shoulder rank is provided with adaptive and constitute the spacing limited step of guide holder with these shoulder rank.
By adopting such scheme, the guide holder lower end is that stair-stepping purpose is to place seal ring for convenience to reach fixedly elastic sleeve, an end of elastic sleeve is pressed be located between guide holder and the valve body, and rational in infrastructure, processing and installation are all comparatively convenient.
Below in conjunction with accompanying drawing the utility model is further described.
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 high pressure main steam control valve Cast Steel, include valve body 1 and spool 2, described valve body 1 upper end is provided with actuator 3, actuator 3 moves by valve rod 4 control spools 2, thereby realize opening and closing of valve, in the utility model embodiment, described actuator 3 is arranged on the valve body 1 by support 5, the joining place of described support 5 and valve body 1 is provided with the guide holder 6 of valve rod 4, be provided with elastic sleeve 7 between guide holder 6 and the spool 2, be provided with seal ring 8 between described guide holder 6 and the elastic sleeve 7.Adopt such scheme, the problem that the utility model can well the customer service prior art exists provides a kind of good sealing effect, the stop valve of long service life, be provided with seal ring 8 between guide holder 6 and the elastic sleeve 7 in addition, being provided with of seal ring 8 can guarantee its sealing.
In the utility model embodiment, described guide holder 6 lower ends are stepped, and the end of elastic sleeve 7 one ends is fastened on the stepped portion of guide holder 6, and the stepped portion of guide holder 6 offers short slot, and described seal ring 8 places in this short slot; The side face that described guide holder 6 is connected with valve body 1 is provided with shoulder rank 61, the corresponding part on valve body 1 and these shoulder rank 61 is provided with adaptive and constitute the spacing limited step 11 of guide holder 6 with this shoulder rank 61, adopt such scheme, guide holder 6 lower ends are that stair-stepping purpose is to place seal ring 8 for convenience to reach fixedly elastic sleeve 7, the one end pressure of elastic sleeve 7 is located between guide holder 6 and the valve body 1, rational in infrastructure, processing and installation are all comparatively convenient.
