Abstract
The invention relates to a temperature control valve comprising a valve body, a pressure rod, a piston cylinder and a piston component. The lower portion of the valve body is provided with a water outlet. The water outlet in the valve body is fitted with the piston component. The pressure rod passes through the piston cylinder, while the lower portion of the pressure rod is connected with the piston component. A water passage formed in the pressure rod is provided with an upper opening on the pressure rod wall on the upper portion of the piston cylinder and a lower opening on the pressure rod wall between the lower portion of the piston cylinder and the piston component. The lower opening is provided with a protective film. Through the water passage of the pressure rod and an effectively hermetic protective cap on the upper portion of the pressure rod, overflowing water around the pressure rod on the upper portion of the valve body can be pressed back into the valve body, so that reacting force upon an actuator is reduced, the service life of a seal ring is prolonged and the problem of water leakage is better solved.
Description
Technical field
This patent belongs to flow control valve, is specifically related to a kind of thermostat valve.
Background technique
The process that changes along with heat in recent years, thermostat valve is widely used.The piston cylinder that old thermostat valve and electric heating valve, depression bar are passed valve body top utilizes actuator, expands with heat and contract with cold or stepper motor as thermometer bulb, controls descendingly, and the piston assembly that drives the bottom cooperates valve body with water outlet.
Because there is the space cooperation place of piston cylinder and depression bar, water in the valve body easily overflows from here, thermostat valve is leaked, the application number of Quan Longhao application on the 11st November in 2009 is " a kind of leakproof thermostatic valve of adjustable KV value " employing seal ring leakproof of 200910237130.6, this structure is conducive to prevent from leaking, but when quick closedown, water in the seal ring can not push back valve body fast from the space of piston cylinder and depression bar, easily cause seal ring distortion and leak, the reaction force to actuator is also bigger simultaneously.
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; the hydraulic pressure that overflows around the depression bar of valve body top can be back in the valve body; minimizing improves sealing effect and the life-span of seal ring to the reaction force of actuator, solves 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 the described valve body cooperates with piston assembly, and described depression bar passes piston cylinder, and the bottom is connected with piston assembly; be provided with the passage of water flowing in the 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 the 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 the top cooperates with the protective cap end face that is provided with the 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 axle is hollow I-shaped centered by the axial cross section of described upper ring surface, all cooperate with supporting post upper and lower surface and axis, under the pressure of water, seal ring closely is set on the supporting post, good sealing effect.
Preferably, the corresponding under shed of described protective film is set on the 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 moved downwards, pressure reduction can be that the hydraulic pressure that seal ring seals in the protective cap is gone into passage inflow valve inner with piston cylinder top; When depression bar upwards moves, reflux because the protective film of under shed stops water, thus, reduced in the seal ring water to the reaction force of actuator, thereby also be difficult for allowing the seal ring distortion prolong the working life of seal ring.
2) inside of this patent protective cap arranges dismountable supporting post, sheathed and its three close-fitting seal rings on the supporting post, and good sealing effect prevents from leaking.
Description of drawings
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; 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 the described valve body cooperates with piston assembly 4; described depression bar 2 passes piston cylinder 3; the bottom is connected with piston assembly 4; be provided with the passage 6 of water flowing in the 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 the 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 the top cooperates with the end face of the protective cap 10 that is provided with the 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; axle is hollow I-shaped centered by the axial cross section of described upper ring surface; working surface 14 on it, working surface 15 is respectively and the surface engagement between the supporting post 11 I-shaped upper and lower surfaces down; under the pressure of water; seal ring 12 closely is set on the 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 subjected to drive unit to promote operation downwards, pressure reduction can with piston cylinder 3 tops namely 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 moved, the protective films 9 outer because of under shed 8 stoped water to reflux, if water overflows to top by the slit of 2 of piston cylinder 3 and depression bars, meeting be sent back to valve inner through said process, and thus, the problem that depression bar place, valve body top easily leaks is solved.
This patent above-described embodiment only is 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.
