Description
[technical field]
The present invention relates to a kind of drain valve, especially relate to a kind ofly be installed on the water circuit system, the self-draining drain valve of low temperature.
[background technique]
In the winter of northern China, the temperature in overwhelming majority area is in one long period, all be in below 0 ℃, some use the utensil (as gas water-heater etc.) of water circuit systems, its water pipe can not get insulation because of a variety of causes, make wherein water pipe because of freezing bursting by freezing, cause damage for user's family's property; Though on the utensil of some use water circuit systems Decompression valves is installed, but Decompression valves mainly backs down valve by hydraulic pressure, and the adjusting of Decompression valves is very inaccurate, usually in the needs draining, do not drive valve, cause the bursting by freezing of water circuit system water pipe, make troubles and lose to user life, also bring loss to manufacturer.Antifreezing measure in this respect generally adopt the electrical heating antifreezing system at present, promptly electric heating tube is installed at some position of water pipe in gas water-heater, and this measure can be played antifreezing effect, but its cost height, power consumption is many, and just can not bring into play its antifreeze function when taking place to have a power failure.
[summary of the invention]
The present invention has overcome the deficiencies in the prior art, and a kind of simple in structure, easy to implement, cost is low, resistance to frost is good low warm water discharge drain valve is provided.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposal:
A kind of have a self-draining drain valve of low temperature, comprise valve body, water supply connector, water output connector, it is characterized in that being provided with in the described body cavity slidably sliding assembly, water shutoff step, make sliding assembly flow channel can be cut off when on the water shutoff step, sliding; The heat sensitive material staving is housed between water supply connector and sliding assembly, and the heat sensitive material staving is connected with sliding assembly; Fill heat sensitive material in the heat sensitive material staving, the opening of heat sensitive material staving is provided with diaphragm, and diaphragm is withstood by push rod one end, and the other end of push rod is connected with water output connector; Between water supply connector and heat sensitive material staving, be provided with spring;
Aforesaid sliding assembly comprises sliding seat, sealing seat, seal ring, and the heat sensitive material staving is connected with sliding seat, and sliding seat and sealing seat are by being threaded, and sealing seat is provided with seal ring, and seal ring cooperates with the water shutoff step;
The other end of aforesaid push rod is connected with water output connector by regulating plug screw; Regulate plug screw and water output connector by being threaded;
Be provided with transverse holes, vertical hole in the aforesaid adjusting plug screw, transverse holes, vertically hole conducting, transverse holes is connected with body cavity, and vertically the hole is connected with the external world;
Be provided with round platform hole and pilot hole in the aforesaid sliding seat; Push rod is inserted in the pilot hole.
The present invention compared with prior art has following advantage:
This functional structure is uncomplicated, implements also very convenient; The experiment proved that be applicable to existing most gas water-heater or other need with pipeline that water circuit system is connected in, be used for pressure release, draining, safety protection aspect such as antifreeze, applied range, cost is low, prospect is better.
[description of drawings]
Fig. 1 is the generalized section that this drain valve is in closed condition;
Fig. 2 is the generalized section that this drain valve is in open mode.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
See Fig. 1,2, a kind of have a self-draining drain valve of low temperature, comprise valve body 1, water supply connector 2, water output connector 3, it is characterized in that being provided with in the body cavity slidably sliding assembly 4, water shutoff step 5, make sliding assembly flow channel can be cut off when on the water shutoff step, sliding; Heat sensitive material staving 6 is housed between water supply connector and sliding assembly, and the heat sensitive material staving is connected with sliding assembly; Fill heat sensitive material 7 in the heat sensitive material staving, the opening of heat sensitive material staving is provided with diaphragm 8, and diaphragm is withstood by push rod 9 one ends, and the other end of push rod is connected with water output connector; Between water supply connector and heat sensitive material staving, be provided with spring 10.
When heat sensitive material expands when setting temperature is above, stretch to the diaphragm direction, because push rod maintains static, therefore heat sensitive material staving drive heat sensitive material, sliding seat, sealing seat, seal ring move to the water supply connector direction, spring is shortened, seal ring contacts with the water shutoff step of valve interior wall, and current are closed sealing (as shown in Figure 1);
When heat sensitive material shrinks when setting temperature is following, because push rod maintains static, promoting the heat sensitive material staving under the effect of spring moves to the push rod direction, heat sensitive material staving drive heat sensitive material, sliding seat, sealing seat, seal ring move to the water output connector direction, seal ring separates with the water shutoff step of valve interior wall, and current are opened (as shown in Figure 2).
Described drain valve is a kind of low temperature pressure releasing and antifreezing device that connects with inipple in the bypass of water circuit system, and when the water temperature of water circuit system was higher than setting temperature, drain valve was in closed condition; When the water temperature of water circuit system is lower than setting temperature and during near 0 ℃; drain valve is in the water flowing state; make the water in the water circuit system be in flowing state; utilize the water temperature in the water temperature heating water circuit system of tap water; before water circuit system freezes, can play the draining pressure release, make water circuit system avoid spalling; play the effect of anti-frost protection water pipe, promptly water circuit system is had draining, pressure release, antifreeze effect.
The other end of push rod is connected with water output connector by regulating plug screw 11; Regulate plug screw and water output connector by being threaded, regulate plug screw 11 and can pass through threaded adjusting, make push rod and spring degree of tightness moderate, accurately regulate the mobile of sliding seat, sealing seat, seal ring, with controlled water flow close and open-minded.Regulate and be provided with transverse holes 111, vertical hole 112 in the plug screw 11, transverse holes, vertically hole conducting, transverse holes is connected with body cavity, and vertically the hole is connected with the external world, regulates plug screw and is in normal open state.
Be provided with round platform hole 411 and pilot hole 412 in the sliding seat 41, the round platform hole communicates with pilot hole; The round platform hole provides the space of distortion when be out of shape by the heat sensitive material expansion for diaphragm; Push rod is inserted in the pilot hole, thereby sliding seat can slide along push rod, and push rod plays the effect of guiding.
Heat sensitive material has identical expansion and contracted length in range of set temperature.
