Abstract
The utility model relates to a regulating valve which comprises a valve body, a valve seat and a valve core. The valve seat is arranged in the valve body, the valve core is arranged in the valve base, a first step and a second step are arranged on the valve body and the valve seat respectively, the first step is matched with the second step, a gasket is arranged between the first step and the second step, a pressing barrel used for pressing the second step to the first step tightly is arranged on the valve seat, an annular groove matched with the pressing barrel is formed in the top of the valve seat, the pressing barrel is arranged in the annular groove, the annular groove butts against the wall of the first step, and the thickness of the pressing barrel is identical with the width of the first step. According to the regulating valve, leakage is avoided, when the regulating valve is maintained, the valve body and the valve seat can be detached only by taking down the pressing barrel, maintenance is convenient, and maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of modulating valve, relates in particular to a kind ofly for controlling the modulating valve of fluid flow, belongs to valve technology field.
Background technique
Along with scientific and technical progress, be used for controlling the modulating valve of fluid flow in the production automation generally for industry-by-industry.And, for heating power, chemical industry control system, as the modulating valve of the every quality of final control procedure medium and safety index, at aspects such as steady production, optimization control, maintenance and cost of overhaul controls, play an important role.The regulating valve structure of prior art as described in Figure 1, comprises valve body 1, valve seat 2 and spool 3, in described valve body 1, is provided with valve seat 2, in described valve seat 2, is provided with spool 3, and valve body 1 is connected by screw thread with valve seat 2.There are 2 points the leak point of the modulating valve of this structure, and the first leak point 4 and the second leak point 5, as not high as the precision of screw thread processing, just be easy to cause medium to reveal from the second leak point, also easily make spool and valve seat decentraction, i.e. the first place, leak point contact is bad, causes revealing simultaneously; Need modulating valve is keeped in repair after revealing, modulating valve need to be dismantled during maintenance, because valve body is connected by screw thread with valve seat, use for a long time the phenomenon that forms " killing ", dismounting inconvenience, maintenance difficulty is large, and maintenance cost is high.
The model utility content
The utility model purpose is in order to overcome the deficiencies in the prior art, to provide a kind of difficult generation to leak and modulating valve easy to maintenance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of modulating valve, comprise valve body, valve seat and spool, be provided with valve seat in described valve body, be provided with spool in described valve seat, be respectively equipped with the first step and the second step that cooperatively interact on described valve body and valve seat, between described first step and second step, be provided with packing ring; Described valve seat is provided with for second step being pressed on to the pressure cylinder on first step.
Preferably, described valve seat top has the circular groove be complementary with pressure cylinder; Described pressure cylinder is arranged in circular groove.
Preferably, described circular groove is near the wall of first step.
Preferably, the width of the thickness of described pressure cylinder and first step is identical.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Modulating valve of the present utility model, be provided with packing ring between the second step due to the first step of valve body and valve seat, and two original leak points are reduced to one, as long as course of working is controlled, obtains, and reveals and just can avoid; And valve seat is pressed on by pressure cylinder on the first step of valve body, during maintenance, as long as take off pressure cylinder, just valve body and valve seat can be split, easy to maintenance, reduced maintenance cost.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation of the modulating valve that accompanying drawing 1 is prior art;
The structural representation that accompanying drawing 2 is modulating valve of the present utility model;
Wherein: 1, valve body; 2, valve seat; 3, spool; 4, the first leak point; 5, the second leak point; 6, first step; 7, second step; 8, packing ring; 9, pressure cylinder; 10, circular groove.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of modulating valve as shown in Figure 2, comprise valve body 1, valve seat 2 and spool 3, be provided with valve seat 2 in described valve body 1, be provided with spool 3 in described valve seat 2, be respectively equipped with the first step 6 and the second step 7 that cooperatively interact on described valve body 2 and valve seat 3, between described first step 6 and second step, 7 are provided with packing ring 8; Described valve seat 2 is provided with for second step 7 being pressed on to the pressure cylinder 9 on first step 6; The thickness of described pressure cylinder 9 is identical with the width of first step 6; Described valve seat 2 tops have the circular groove 10 be complementary with pressure cylinder 9; Described pressure cylinder 9 is arranged in circular groove 10; Described circular groove 10 is near the wall of first step 6.
Modulating valve of the present utility model, be provided with packing ring between the second step due to the first step of valve body and valve seat, and two original leak points are reduced to one, as long as course of working is controlled, obtains, and reveals and just can avoid; And valve seat is pressed on by pressure cylinder on the first step of valve body, during maintenance, as long as take off pressure cylinder, just valve body and valve seat can be split, easy to maintenance, reduced maintenance cost.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
