Abstract
The utility model discloses a core of a temperature-controlled valve, which comprises a valve rod and a piston fixed at the lower part of the valve rod. The utility model is characterized in that a circle of lug boss is arranged in the middle of the valve rod; a conical rubber film is fixed below the lug boss; a conical roof of the conical rubber film extends downward to form a rubber sleeve which is vulcanized with the valve rod together; a conical bottom of the conical rubber film extends to the periphery to form a circular flat pad matched with the lug boss in the valve body. When the utility model is arranged on a valve body, a valve cover is just tightly pressed on a plane at the periphery of the rubber film, which can prevent liquid from permeating and leaking outward. Thus, the utility model can solve the problem of seal between the valve rod and the valve cover. In the process of use, the core of a temperature-controlled valve does not need to be frequently replaced and repaired. Thus, the utility model can be welcomed by users, and is favorable for the popularization and the application of automatic temperature-controlled valves.
Description
Technical field
The utility model relates to a kind of valve fittings, relates in particular to a kind of spool that is applicable to automatic temperature control valve, high resistant valve and stop valve etc.
Background technique
The spool of existing automatic temperature control valve, high resistant valve and stop valve all is made up of valve rod and the piston that is fixed on stem lower portion, the unlatching of valve and by all being to realize by moving up and down of spool, along with variation of temperature, spool need often move up and down the size of adjusting fluid flow in the valve body, will make between valve rod and the valve gap like this and produce the slit, outwards seepage liquid.So in use just need often change and keep in repair the spool that has automatic temperature control valve now, to the heating unit with causing inconvenience per family, so that be unfavorable for the promotion and application of automatic temperature control valve.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned shortcoming, thereby provides a kind of sealing problem that can solve between valve rod and the valve gap to prevent the thermostat valve spool of outside seepage liquid.
For reaching above-mentioned purpose, the utility model adopts following solution: comprise valve rod and the piston that is fixed on stem lower portion, it is characterized in that: a circle boss is set at the middle part of valve rod, at the fixing rubber membrane of taper of the bottom of boss, the vertex of a cone of rubber membrane extends to form a rubber case downwards and valve rod sulfides, and extends to the periphery at the bottom of the awl of rubber membrane to form the plain cushion that the circular boss with valve inner is complementary.
Using process of the present utility model is: spool is installed on the valve body, tightens valve gap then, this moment, valve gap tightly suppressed on the plane of the rubber membrane periphery that sulfides with valve rod, can play seal action like this, prevented outside seepage liquid.When valve rod was not subjected to external force, rubber membrane was in free state, and valve is opened automatically; When valve rod was stressed, rubber membrane moved down with valve rod, promoted piston and made valve closing.
Compared with prior art, the utlity model has following advantage:
Because the utility model is provided with rubber membrane at the middle part of valve rod, in the time of on being installed to valve body, valve gap just in time tightly suppresses on the plane of rubber membrane periphery, can prevent that liquid from leaking to exosmosis, so the utility model can solve the sealing problem between valve rod and the valve gap, the trouble of often replacing and maintenance in use just can not occur, thereby can be subjected to user's welcome, help applying of automatic temperature control valve.

Embodiment
As shown in Figure 1, the utility model comprises valve rod 7, at the bottom of valve rod 7 fixed piston 2, on piston 2, be with piston pad 1, one circle boss 6 is set at the middle part of valve rod 7, at the fixing rubber membrane 5 of taper of the bottom of boss 6, the vertex of a cone of rubber membrane 5 extends to form a rubber case 3 downwards and sulfides with valve rod 7, extends to the periphery at the bottom of the awl of rubber membrane 5 to form the plain cushion 4 that the circular boss with valve inner is complementary.
As shown in Figure 2, the utility model is installed in it on valve body 10 earlier in use, tightens valve gap 8 then, and this moment, the plain cushion 4 of rubber membrane 5 just in time was shelved on the boss in the valve body 10, valve gap 8 is pressed on the rubber membrane 5, is provided with pad 9 between the plain cushion 4 of valve gap 8 and rubber membrane 5.Therefore the utility model can play seal action, prevents the outside seepage of liquid.When valve rod 7 was not subjected to external force, rubber membrane 5 was in free state, and valve is opened (as shown in Figure 2) automatically; When valve rod 7 was stressed, rubber membrane 5 moved down with valve rod 7, promoted piston 2 and made valve closing.
