Abstract
The utility model relates to a thermostat valve which comprises a valve body, a pressing rod, a piston cylinder and a piston assembly. A water outlet is formed in the lower portion of the valve body and matched with the piston assembly. The pressing rod penetrates through the piston cylinder. The lower portion of the pressing rod is connected with the piston assembly. A water-passing channel is formed in the pressing rod. An upper opening is formed in the pressing rod wall of the upper portion of the piston cylinder of the channel. A lower opening is formed in the pressing rod wall between the lower portion of the piston cylinder and the piston assembly. The lower opening is provided with a protection film. According to the thermostat valve, water overflowing out of the periphery of the pressing rod of the upper portion of the valve body is pressed back into the valve body through the water-passing channel arranged in the pressing rod and a protection cap which is good in sealing effect and arranged on the upper portion of the pressing rod and thus, reactive force on an executing mechanism is reduced, the service life of a sealing ring is prolonged and the problem of water leaking is solved.
Description
Technical field
The utility model belongs to flow control valve, is specifically related to a kind of thermostat valve.
Background technique
The process changed along with heat in recent years, thermostat valve is widely used.Old thermostat valve and electric heating valve, depression bar, through the piston cylinder on valve body top, utilizes actuator, as thermometer bulb expands with heat and contract with cold or stepper motor, controls descendingly, and the piston assembly that drives bottom coordinates with water outlet, valve body.
Because there is space the cooperation place of piston cylinder and depression bar, water in valve body easily overflows from here, thermostat valve is leaked, " a kind of leakproof thermostatic valve of adjustable KV value " that the application number of Quan Longhao application on the 11st November in 2009 is 200910237130.6 adopts the seal ring leakproof, this structure is conducive to prevent from leaking, but when quick closedown, water in seal ring can not push back valve body fast from the space of piston cylinder and depression bar, easily cause sealed ring deformation and leak, simultaneously also larger to the reaction force of actuator.
Summary of the invention
The technical problems to be solved in the utility model is; a kind of thermostat valve is provided; the depression bar of this valve body arranges the passage of water flowing; depression bar top is provided with the extraordinary protective cap of sealing effect; the hydraulic pressure overflowed around the depression bar of valve body top can be back in valve body; the reaction force of minimizing to actuator, sealing effect and the life-span of improving seal ring, solve seepy question.
For achieving the above object, the utility model is by the following technical solutions:
A kind of thermostat valve; comprise valve body, depression bar, piston cylinder and piston assembly; described valve body lower portion is provided with water outlet; water outlet in described valve body coordinates with piston assembly, and described depression bar is through piston cylinder, and bottom is connected with piston assembly; be provided with the passage of water flowing in described depression bar; this passage arranges upper shed at the depression bar wall on the top of piston cylinder, in the bottom of piston cylinder and the depression bar wall between piston assembly, under shed is set, and described under shed is provided with protective film.
Preferentially, described depression bar top is provided with the protective cap of seal ring, and protective cap inside is provided with the supporting post for sheathed seal ring, and this supporting post axial cross section is I-shaped, and top coordinates with the protective cap end face that is provided with hole; The sheathed seal ring of the axis of described supporting post.
Preferably, described seal ring comprises upper ring surface and frustoconic shape shirt rim, and centered by the axial cross section of described upper ring surface, axle is hollow I-shaped, with supporting post upper and lower surface and axis, all coordinate, under the pressure of water, seal ring closely is set on supporting post, good sealing effect.
Preferably, the corresponding under shed of described protective film is set on depression bar.
The utility model compared with prior art has the following advantages:
1) depression bar of the present utility model arranges the passage of hollow, and when depression bar moves downwards, pressure reduction can be that the hydraulic pressure that in protective cap, seal ring seals enters passage inflow valve inner by piston cylinder top; When depression bar upwards moves, the protective film prevention water backflow because of under shed, thus, reduced the reaction force of water to actuator in the seal ring, thereby also be difficult for allowing sealed ring deformation extend the working life of seal ring.
2) inside of the utility model protective cap arranges dismountable supporting post, sheathed and its three close-fitting seal rings on supporting post, and good sealing effect, prevent from leaking.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is seal ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment 1
As shown in Figure 1; the present embodiment comprises valve body 1, depression bar 2, piston cylinder 3 and piston assembly 4; described valve body 1 bottom is provided with water outlet 5; water outlet 5 in described valve body coordinates with piston assembly 4; described depression bar 2 is through piston cylinder 3; bottom is connected with piston assembly 4; be provided with the passage 6 of water flowing in described depression bar 2; this passage 6 arranges upper shed 7 at the depression bar wall on the top of piston cylinder; in the bottom of piston cylinder 3 and the depression bar wall between piston assembly 4, under shed 8 is set respectively, described under shed 8 is provided with protective film 9.
Described depression bar 2 tops are provided with the protective cap 10 of seal ring, and protective cap 10 inside are provided with the supporting post 11 for sheathed seal ring, and these supporting post 11 axial cross sections are I-shaped, and top coordinates with the end face of the protective cap 10 that is provided with hole, the sheathed seal ring 12 of axis.
As shown in Figure 2; described seal ring 12 comprises upper ring surface 13 and frustoconic shape shirt rim 16; centered by the axial cross section of described upper ring surface, axle is hollow I-shaped; on it, working surface 14, lower working surface 15 are respectively and the surface engagement between the I-shaped upper and lower surface of supporting post 11; under the pressure of water; seal ring 12 closely is set on supporting post 11, and 16 supports of frustoconic shape shirt rim are at protective cap 10 inboards, good sealing effect.
During use, described depression bar 2 is subject to drive unit to promote operation downwards, pressure reduction can by piston cylinder 3 tops the water in protective cap 10 be pressed into passage 6 through upper shed 7, flow into valve body 1 inside, thereby avoid top to leak; When depression bar 2 upwards moves, the protective film 9 outer because of under shed 8 stops water to reflux, if water by the Yi Dao top, gap of 2 of piston cylinder 3 and depression bars, meeting be sent back to valve inner through said process, thus, the problem that depression bar place, valve body top easily leaks is solved.
The utility model above-described embodiment is only this patent mode of execution preferably, and the structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection domain of this patent.
