Abstract
The present invention relates to 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; the passage of water flowing is provided with in described depression bar; this passage arranges upper shed at the depression bar wall on the top of piston cylinder, and the depression bar wall between the bottom and piston assembly of piston cylinder arranges under shed, and described under shed is provided with protective film.The water flowing passage that this patent is arranged by depression bar and depression bar top arrange with the extraordinary protective cap of sealing effect; can the hydraulic pressure overflowed around the depression bar of valve body top be back in valve body; thus reduce the reaction force of actuator and extend working life of seal ring, solve seepy question better.
Description
Technical field
This patent belongs to flow control valve, is specifically related to a kind of thermostat valve.
Background technique
In recent years along with the process that heat changes, 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 descending, drives the piston assembly of bottom to coordinate 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, the application number of Quan Longhao application on the 11st November in 2009 be 200910237130.6 " a kind of leakproof thermostatic valve of adjustable KV value " adopt seal ring leakproof, this structure is conducive to preventing 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 problem that this patent will solve 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; can the hydraulic pressure overflowed around the depression bar of valve body top be back in valve body; reduce the reaction force to actuator, improve sealing effect and the life-span of seal ring, solve seepy question.
For achieving the above object, this patent 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; the passage of water flowing is provided with in described depression bar; this passage arranges upper shed at the depression bar wall on the top of piston cylinder, and the depression bar wall between the bottom and piston assembly of piston cylinder arranges under shed, 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 being provided with hole; The sheathed seal ring of 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, all coordinate with supporting post upper and lower surface and axis, under the pressure of water, seal ring is closely on the support columns sheathed, good sealing effect.
Preferably, the corresponding under shed of described protective film is set on depression bar.
This patent compared with prior art has the following advantages:
1) depression bar of this patent arranges the passage of hollow, and when depression bar runs downwards, the hydraulic pressure that seal ring in piston cylinder top and protective cap seals can be entered passage and flow into valve inner by pressure reduction; When depression bar upwards runs, the protective film because of under shed stops water backflow, thus, to reduce in seal ring water to the reaction force of actuator, also not easily allows sealed ring deformation thus extend working life of seal ring.
2) inside of this patent protective cap arranges dismountable supporting post, and sheathed with its three close-fitting seal rings on supporting post, good sealing effect, prevents from leaking.
Accompanying drawing explanation
Fig. 1 is the structural representation of this patent;
Fig. 2 is the structural representation of seal ring.
Embodiment
Below in conjunction with accompanying drawing, this patent 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; the passage 6 of water flowing is provided with in described depression bar 2; this passage 6 arranges upper shed 7 at the depression bar wall on the top of piston cylinder; depression bar wall between the bottom of piston cylinder 3 and piston assembly 4 arranges under shed 8 respectively, and described under shed 8 is provided with protective film 9.
Described depression bar 2 top is provided with the protective cap 10 of seal ring, and protective cap 10 inside is provided with the supporting post 11 for sheathed seal ring, and this supporting post 11 axial cross section is I-shaped, and top coordinates with the end face of the protective cap 10 being 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; working surface 14, lower working surface 15 surface engagement respectively and between the I-shaped upper and lower surface of supporting post 11 on it; under the pressure of water; seal ring 12 closely sheathed on the support columns 11, frustoconic shape shirt rim 16 is supportted inside protective cap 10, good sealing effect.
During use, described depression bar 2 promotes to run downwards by drive unit, and the water of piston cylinder 3 top namely in protective cap 10 can be pressed into passage 6 through upper shed 7 by pressure reduction, flows into valve body 1 inner, thus avoids top to leak; When depression bar 2 upwards runs, because the protective film 9 outside under shed 8 stops water to reflux, if water overflows to top by the gap between piston cylinder 3 and depression bar 2, can be sent back to valve inner through said process, thus, depression bar place, valve body top leakiness water problem is solved.
This patent above-described embodiment is only the good mode of execution of this patent, the structure that all employing the technical program describes, feature and the change in its spiritual principle, modifies the protection domain all belonging to this patent.
