Abstract
The utility model relates to a disc-type trap valve which comprises a valve body, a valve seat, a valve plate, a valve cover, a filter mesh and a plug; the valve body is provided with a water inlet and a water outlet; the valve seat is arranged in the valve body; the valve plate is arranged above the valve seat; the valve cover is arranged above the valve plate, and is fixedly connected with the valve body through a thread; the plug seals the filter mesh in the valve body; the bottom surface of the valve seat is provided with a circular groove; and the circular groove is communicated with the drainage hole of the valve body. Compared with the prior art, the disc-type trap valve has the advantages of large displacement; and because the bottom of the valve seat is provided with the circular groove, the valve seat does not need to be fixed any more, thereby greatly simplifying the manufacturing process and the assembly speed, shortening the product manufacturing time, and reducing the manufacturing cost.
Description
Technical field
The utility model relates to drain valve, relates in particular to Shemostatic team trap.
Background technique
Existing Shemostatic team trap mainly is made up of valve body, valve seat, valve block, valve gap, filter screen, plug etc., when steam and water of condensation during by drain valve, because the variation of dynamic pressure and static pressure, impels valve block to rise or descends, and plays the effect of block steam and drain water.When the drain valve inlet pressure raises, by the water inlet valve block is lifted, water of condensation is discharged from osculum, water of condensation is discharged the control room that back steam enters the valve block rear portion, because the air pressure in control room raises, valve block rear portion pressure closes valve block greater than water inlet pressure.After the static pressure in control room descended, valve block was lifted again, and interruption is discharged water of condensation periodically like this.But the relative position of the valve seat of prior art and valve body need be fixed, and the weep hole of the valve seat of prior art only has one, also needs to tilt to be communicated with the weep hole of valve body, and part is difficult to processing, scrappage height.This makes water displacement can't increase substantially always.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of Shemostatic team trap simple in structure to be provided.
The purpose of this utility model can be achieved through the following technical solutions: Shemostatic team trap, comprise valve body, valve seat, valve block, valve gap, filter screen, plug, described valve body is provided with water intake, water outlet, described valve seat is located in the valve body, described valve block is located at the valve seat top, described valve gap is located at the valve block top, it is fixing to be threaded with valve body, described plug is sealed in filter screen in the valve body, it is characterized in that, the bottom surface of described valve seat is provided with annular groove, and this annular groove is communicated with the valve body weep hole.
Described valve seat is provided with at least one valve seat osculum.
Described valve seat is provided with three valve seat osculums, is evenly distributed on the annular groove.
Compared with prior art, the utility model has the advantages that discharge capacity is big and be provided with annular groove bottom valve seat, thereby make valve seat no longer need to fix, simplified manufacturing process and assembling speed greatly, shortened the time that product is made, reduced manufacture cost.

Fig. 3 is the worm's eye view of the valve seat of the utility model Shemostatic team trap.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
As Fig. 1～shown in Figure 3, the utility model Shemostatic team trap, comprise valve body 2, valve seat 8, valve block 7, valve gap 1, filter screen 4, plug 3, valve body is provided with water intake 5, water outlet 6, valve seat 8 is located in the valve body 2, and valve block 7 is located at valve seat 8 tops, and valve gap 1 is located at valve block 7 tops, it is fixing to be threaded with valve body 2, and plug 3 is sealed in filter screen 4 in the valve body 2.Between valve seat 8 and the valve body 2, be equipped with gasket seal 9 between valve gap 1 and the valve seat 8.
Described valve seat 8 is provided with valve seat water inlet 82.The bottom surface of valve seat 8 is provided with annular groove 81, this annular groove 81 and valve body weep hole UNICOM.Valve seat 8 also is provided with three valve seat osculums 83 and is evenly distributed on the annular groove 81.When drain valve work, when valve block lifted, water of condensation entered from valve seat water inlet 82, was expelled in the annular groove 81 from three valve seat osculums 83, discharged from valve body weep hole 10 again.Like this, carry out draining, just significantly increased the discharge capacity of drain valve by three valve seat osculums 83; And, the annular groove 81 of valve seat bottom can make three valve seat osculums 83 be communicated with valve body weep hole 10 in 360 ° of scopes, thereby the relative position that does not need fixed valve base and valve body, manufacturing process and product and assembling speed have so just been simplified, shorten the time that product is made, reduced manufacture cost.
