Abstract
The utility model relates to a motorized valve body assembly, in central air-conditioning equipment engaging with the driver and the thermoregulator as valve on-off to accomplish temperature regulating, which comprises a shell, a valve bonnet seal connected with the shell, the valve bonnet is provided with a valve core to start and stop the valve, the valve core comprises a valve rod capable of up-and-down sliding and a flap synchronously moving with the valve rod, an insert constructing the soft and hard plane sealed valve and an offsetting spring resetting the valve close are arranged on the joint of the valve bonnet and the flap. The utility model compares with the prior art, canceling the valve seat part, simplifying the structure, the plane soft and hard seal measure enhances the seal performance, which has characters of simple structure, excellent sealed performance, not leakage, compact on-off, elongation of the service life and the like.
Description
Technical field
The utility model relates to the auxiliary products of central air conditioning equipment---mortor operated valve valve body part, be and drive mouthful, the supporting mortor operated valve valve body assembly parts of realizing the temperature regulating and controlling as valve opening and closing that makes of temp controller.
Background technique
Mortor operated valve valve body assembly parts is that central air-conditioner is realized thermoregulator auxiliary products as valve opening and closing, and its medium that is suitable for is chilled water, hot water or low pressure steam, requires this product to have higher intensity and excellent sealing performance.Existing mortor operated valve valve body adopts piston cylinder operator, be provided with valve seat in the valve body, the spool of opening/shutting valve is sealed by " O " RunddichtringO, and " O " RunddichtringO is located in the dovetail groove between valve seat and the valve gap, not only structurally increased the valve seat part, make complex structure, fluvial processes is easily stopped up by impurity, makes valve opening very heavy; " O " RunddichtringO that is located at simultaneously in the dovetail groove is easily jumped out in groove when loine pressure increases, make sealing malfunctioning and cause leaking, this is an one, next is the sealing problem of spool and housing inner chamber, and owing to spool is connected with housing by valve seat, so the sealing of spool and valve seat is to consider, the seal groove of " O " RunddichtringO of its sealing is opened in valve seat, both increased difficulty of processing, increased slip resistance again, thereby reduced seal degree and working life.
Summary of the invention
Technical problem to be solved in the utility model proposes a kind of simplified structure, improves the sealability and the mortor operated valve valve body assembly parts in working life all in the defective that overcomes on the existing mortor operated valve valve body structure.
Technical problem of the present utility model realizes by following technical proposal: mortor operated valve valve body assembly parts, it comprises the housing that has into and out of the water hole, be provided with the valve gap that is tightly connected in the housing, be provided with the spool of the opening/shutting valve that is tightly connected with it in the valve gap, this spool comprise can upper and lower slip valve rod and with the valve rod synchronization motion constitute the flap of valve with the valve gap junction plane, and the Returnning spring of throttle down, it is characterized in that described valve gap and flap junction are provided with the inserts that constitutes soft or hard plane sealing valve.
The junction plane of described flap and housing inner chamber axis hole is provided with " O " RunddichtringO.
Described Returnning spring be arranged at spiral-lock on valve rod spring washer and valve gap between the shoulder, and with the back-up ring axial limiting.
Compared with prior art, the utility model at first simplifies the structure, cancelled the valve seat part, avoided the foreign material blockage problem of flowing water link, the valve place that valve gap combines with spool has adopted plane soft and hard seal measure, has improved sealability greatly, and the sealing of spool bottom and housing inner chamber has alleviated slip resistance, therefore this case have simple in structure, favorable sealing property is water-tight, switch opens and closes lightly, characteristics such as increase the service life.
Description of drawings
Fig. 1 has provided the utility model structural representation (valve closing state).
Embodiment
By above-mentioned accompanying drawing embodiment, the utility model remakes following detailed description.
Referring to Fig. 1, housing 1 both sides of mortor operated valve valve body assembly parts be on the same shaft axis into and out of the water hole, middle part inner chamber axis hole is coaxial with top boss axis hole and with vertical into and out of the water hole shaft axis, valve gap 3 is threaded with housing 1 top boss axis hole, seals with " O " RunddichtringO 2 on the junction plane at the bottom of the hole.Be provided with the valve core structure in the form of piston of opening/shutting valve in the valve gap 3, this spool comprises and is located in the valve gap concentric circle with 9 sealings of " O " RunddichtringO and valve rod 8 that can upper and lower slip and is located at the fixing flap 10 of valve rod lower end riveted, the upper and lower slip of valve rod drives the flap synchronization lifting and makes valve opening and closing, the junction plane of it and valve gap adopts with valve gap and pushes down one and gluing rubber inserts 4, constitutes the valve of soft or hard plane sealing combination.
On the junction plane of flap 10 and housing 1 inner chamber axis hole, be provided with " O " RunddichtringO 11 that is inlaid in the flap annular groove, prevent to cause when valve from not opening that housing leaks.
The drive motor of this mortor operated valve valve body assembly parts and central air conditioning equipment, the supporting use of temperature detect switch (TDS).According to the needs of seasonal variations room temperature, earlier by the temp controller setting temperature.When summer, when room temperature is higher than the temperature that temp controller sets, driver is started working, motor is depressed valve rod 8 drive flaps 10 and is separated with inserts 4, valve open, this moment, Returnning spring 7 was compressed, and cold water, is entered fan coil unit again and produces refrigeration through the flow direction valve osculum by housing 1 water inlet.When room temperature reached setting temperature, driver was worked again, cancelled the pressure to valve rod 8, and valve rod rises under the effect of Returnning spring 8, drove flap 10 risings and contacted with inserts 4, realized valve closing.
The working principle that heats winter is identical with process of refrigerastion, and medium changes hot water into, when room temperature is lower than the temp controller setting temperature, driver is started working, and opens valve, and hot water enters the fan coil unit generation and heats, until indoor temp controller setting temperature, the valve closing of reaching.
