Abstract
The utility model relates to a kind of Novel ultralow-temperature safety valve, comprise valve body, valve rod, flap, flap seat, adjusting nut and spring, valve rod is arranged on body cavity, flap is arranged on the liquid entering hole place of body cavity, flap is fixedly connected with valve rod, flap can control liquid entering hole and open or close, flap cover for seat is located at outside valve rod, flap seat is fixedly connected with flap, flap seat can slide along valve interior wall, adjusting nut is set in flap seat one end, and adjusting nut is threaded with valve interior wall, is connected between adjusting nut with flap seat by spring.Spring and ultralow temperature medium can be isolated by this Novel ultralow-temperature safety valve; because water loading to cause the problem of spring failure in spring surface condensation when can prevent medium injection from causing spring to enter ultra low temperature state; and ensure that spring is coaxial with the potted line center of circle all the time in movement process; protect the phenomenon that spring will cause spring stuck because of foreign matter, substantially increase working life.
Description
Technical field
The utility model relates to valve field, especially a kind of Novel ultralow-temperature safety valve.
Background technique
Along with the fast development of national LNG relevant industries in recent years, many companies have all carried out the design and development of Cryogenic valve for this market, and its product type contains safety valve, gate valve, stop valve, safety check, ball valve, Emergeny Cutoff Valves etc.Generally all spring is provided with in existing ultralow temperature safety valve, in safety valve opening process, ultralow temperature medium injects directly on safety valve, or safety valve open before and open terminate before medium produce cross-ventilation can cause spring surface freeze, when medium injection causes spring to enter ultra low temperature state, because water loading condenses at spring surface, can spring failure be caused, thus reduce the working life of safety valve.
Model utility content
The technical problems to be solved in the utility model is: can prevent to provide a kind of the Novel ultralow-temperature safety valve that spring is stuck or lost efficacy, improve working life.
The utility model solves the technological scheme that its technical problem adopts: a kind of Novel ultralow-temperature safety valve, comprise valve body, valve rod, flap, flap seat, adjusting nut and spring, described valve rod is arranged on body cavity, described flap is arranged on the liquid entering hole place of body cavity, flap is fixedly connected with valve rod, flap can control liquid entering hole and open or close, described flap cover for seat is located at outside valve rod, flap seat is fixedly connected with flap, flap seat can slide along valve interior wall, described adjusting nut is set in flap seat one end, adjusting nut is threaded with valve interior wall, be connected by spring between adjusting nut with flap seat.
Described flap seat one end offers the first circular groove, adjusting nut one end offers the second circular groove, described both ends of the spring is set in the first circular groove, the second circular groove respectively, and spring can be limited in groove by this structure, prevents spring from skew occurring and causes stuck.
Described flap seat and flap one-body molded, processing is simple, installs more for convenience with valve rod.
The beneficial effects of the utility model are: spring and ultralow temperature medium can be isolated by this Novel ultralow-temperature safety valve; because water loading to cause the problem of spring failure in spring surface condensation when can prevent medium injection from causing spring to enter ultra low temperature state; and ensure that spring is coaxial with the potted line center of circle all the time in movement process; protect the phenomenon that spring will cause spring stuck because of foreign matter, substantially increase working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of Novel ultralow-temperature safety valve of the present utility model;
In figure: 1. valve body, 2. adjusting nut, 3. spring, 4. flap seat, 5. flap, 6. valve rod.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of Novel ultralow-temperature safety valve, comprise valve body 1, valve rod 6, flap 5, flap seat 4, adjusting nut 2 and spring 3, described valve rod 6 is arranged on valve body 1 inner chamber, described flap 5 is arranged on the liquid entering hole place of valve body 1 inner chamber, flap 5 is fixedly connected with valve rod 6, flap 5 can control liquid entering hole and open or close, described flap seat 4 is set in outside valve rod 6, flap seat 4 is fixedly connected with flap 5, flap seat 4 can slide along valve body 1 inwall, described adjusting nut 2 is set in flap seat 4 one end, adjusting nut 2 is connected with valve body 1 inner thread, be connected by spring 3 elasticity between adjusting nut 2 with flap seat 4.
Form an independently cavity between flap seat 4 and adjusting nut 2, spring 3 is arranged in cavity, thus spring 3 and ultralow temperature medium can be made to isolate.The size of this cavity and the degree of tightness of spring 3 can be regulated by rotating adjusting nut 2.Described flap seat 4 one end offers the first circular groove, adjusting nut 2 one end offers the second circular groove, described spring 3 two ends are set in the first circular groove, the second circular groove respectively, and spring 3 can be limited in groove by this structure, prevent spring 3 from skew occurring and causes stuck.
Described flap seat 4 is one-body molded with flap 5, and processing is simple, installs more for convenience with valve rod 6.
When flap 5 is opened, ultralow temperature medium enters valve body 1 inner chamber, and due to the buffer action of flap seat 4, ultralow temperature medium can not contact spring 3, flows out in valve rod 6.
Compared with prior art; spring 3 and ultralow temperature medium can be isolated by this Novel ultralow-temperature safety valve; due to problem that water loading causes spring 3 to lose efficacy in spring 3 surface condensation when can prevent medium injection from causing spring 3 to enter ultra low temperature state; and ensure that spring 3 is coaxial with the potted line center of circle all the time in movement process; protect the phenomenon that spring 3 will cause spring 3 stuck because of foreign matter, substantially increase working life.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
